The mold 1 has a solid, heated mold half 5 and a movable mold half 6 on. The mold halves 5 . 6 are a opposite and by the mobility of the movable mold half 6 relative to each other according to the direction indicated by the arrow A movement direction of the movable mold 6 movable. The movement of the movable mold half 6 relative to the solid mold half 5 that is, the opening and closing movement of the mold halves 5 . 6 , is typical of one of the mold 1 shot or production cycle in which a molding is made. A relative movement of the mold halves 5 . 6 but he can also follow each other without a molding is made. For example, relative movements of the mold halves 5 . 6 during maintenance or removal of at least one of the mold halves 5 . 6 from the mold 1 respectively.

In normal operation of the mold 1 can be calculated from the number of movements of the movable mold half 6 relative to the solid mold half 5 the number of production cycles and thus the number of molds 1 Shots carried out by a detail described below, on the solid mold half 5 the mold 1 provided cycle counter 11 be determined.

The solid mold half 5 the mold 1 has a mounting plate 2 on, with which an attachment of the solid mold half 5 on a machine plate is possible. Adjacent to the mounting plate 2 has the solid mold half 5 a distributor plate 3 on. In the distributor plate 3 is a heatable distributor 16 provided by which, for example, plastic heated and over, for example, in 2 schematically represented channels 17 in valves 8th can be directed.

Adjacent to the distributor plate 3 has the solid mold half 5 a cavity plate 4 with cavities 7 on. The cavities 7 act with opposite cavities 7 in the movable mold half 6 together so that after completion of closing between the fixed and the movable mold half 5 . 6 a closed cavity between the mold halves 5 . 6 is formed, in which a molding can be produced.

The cavity 7 in the cavity plate 4 the solid mold half 5 is over the valve 8th with the distributor 16 the distributor plate 3 in connection. It is especially at the transition of the valve 8th into the cavity 7 at least one seal 10 intended. Through the seal 10 will be a gap between the valve 8th and the cavity plate 4 closed, by which otherwise plastic in the distributor 16 could penetrate and put this uaßer function. In addition, between the valve 8th and the distributor plate 3 an additional seal 9 be provided.

At the distributor plate 3 is the cycle counter 11 attached, which through the cavity plate 4 leads and at the movable mold half 6 opposite front 24 the cavity plate 4 with his front side 19 about completes.

The cycle counter 11 has a housing 12 on, in which at the movable mold half 6 opposite end face 19 a magnet 14 and a reed contact 13 are provided. In other, not shown embodiments of the present invention, the magnet 14 and the reed contact 13 also at another suitable position within the housing 12 of the cycle counter 11 be arranged. It is only necessary that the reed contact 13 within range of the magnetic field of the magnet 14 located and that the magnetic field of the magnet 14 by a movement of the movable mold half 6 can be influenced.

In the in 1 shown embodiment of the present invention is the magnet 14 a permanent magnet. In other, not shown embodiments of the invention, instead of the permanent magnet and an electromagnet can be used.

The reed contact 13 becomes during a movement of the movable mold half 6 in the direction of the solid mold half 5 connected. Thus, any relative movement of the mold halves 5 . 6 through the donor-receiver pair 14 . 13 be recorded. If through a bleed the mold 1 a shot into the mold 1 is introduced and then the mold halves 5 . 6 Close, is due to the closing movement of the movable mold half 6 the shot or production cycle recorded.

The cycle counter 11 further comprises a semi-automatic formed signal acquisition and storage unit 25 that in the example of 1 inside the case 12 of the cycle counter 11 is provided. The signal acquisition and storage unit 25 can then be powered by this power supply when the caster is connected to a power supply. in the simplest case, it is also possible that the signal acquisition and storage unit 25 via a USB port 30 is powered. Will the cycle counter 11 removed, the signal acquisition and storage unit 25 be powered by a battery.

The signal acquisition and storage unit 25 has an electronic time tracking 26 in the form of an electronic clock. The electronic time recording 26 works continuously and is triggered by one in the signal acquisition and storage unit 25 provided battery 27 powered. The battery 27 is in the in 1 shown execution for example, a lithium-thyonyl primary cell. The battery 27 can be used in the signal acquisition and storage unit 25 contained hardware and software components, such as a microcontroller of the signal acquisition and storage unit 25 to power for about two years. It is therefore not necessary for the signal acquisition and storage unit 25 is powered from the outside. As a result, the monitoring device according to the invention for monitoring the mold 1 with the signal acquisition and storage unit 25 work largely independently.

The reed contact 13 does not need to be supplied with power itself, since the reed contact 13 is a passive component. The switching state of the reed contact 13 is passed through the microcontroller of the signal acquisition and storage unit 25 supervised.

By means of electronic time recording 26 anyone can do it through the reed contact 13 measured value assigned to a time value.

The signal acquisition and storage unit 25 also has a control software 28 for controlling hardware components of the signal acquisition and storage unit 25 and a memory 29 for logging and archiving measured values of the cycle counter 11 on.

At the signal acquisition and storage unit 25 is a USB interface 30 for a connection of a computer, a visual display unit or a printer.

In addition, inside the case 12 of the cycle counter 11 another reed contact 15 within range of the magnetic field of the magnet 14 of the cycle counter 11 intended. In the embodiment shown, the further reed contact 15 on a side wall 20 of the housing 12 attached, but in other, not shown embodiments of the present invention, also at another suitable position within range of the magnetic field of the magnet 14 are located.

Will the cavity plate 4 from the distributor plate 3 removed, the reed contact 15 switched and thus the movement of the cavity plate 4 relative to the distributor plate 3 detected.

The switching state of the reed contact 15 can through the signal acquisition and storage unit 25 with recorded, evaluated, stored and / or via the USB interface 30 be transferred to an external recipient.

By the reed contact 15 every movement of the cavity plate 4 from the distributor plate 3 detected by the signal acquisition and storage unit 25 the number of processes in which the cavity plate 4 from the distributor plate 3 was separated. If a predetermined number is detected, can by the signal acquisition and storage unit 25 a signal is generated to the user of the mold 1 indicates that, for example, an exchange of a seal, such as the seal 10 between the valve 8th and the cavity 7 , required or recommended.

In addition, by the reed contact 15 detects a situation in which the cycle counter 11 from the mold 1 is expanded.

Based on the sequence of the reed contact 13 of the cycle counter 11 and the reed contact 15 assumed switching states can also be differentiated, whether the cavity plate 4 from the distributor plate 3 has been pulled away or whether in addition also the cycle counter 11 from the distributor plate 3 was removed. If the cavity plate 4 from the distributor plate 3 is pulled away, this movement process is first by the reed contact 13 of the cycle counter 11 detected during a relative movement of the cavity plate 4 to the movable mold half 6 on. Only later is by the other reed contact 15 the interruption of a connection of the cavity plate 4 to the distributor plate 3 detected.

When the cycle counter 11 is removed, the reed switch 13 of the cycle counter 11 and the reed contact 15 immediately after or at the same time, as in this case both reed contacts 13 . 15 the separation of the cycle counter 11 from the distributor plate 3 detect.

In addition to the another reed contact 15 You can add one or more additional reed contacts 15 within range of the magnetic field of the magnet 14 at the mold 1 be provided. The additional additional reed contacts 15 can the counting function of the reed contact 13 and / or the monitoring function for the cavity plate 4 redundant to the reed contacts 13 . 15 exercise. This increases the interference immunity of the monitoring device according to the invention.

In addition, at least on another removable part of the mold 1 , such as the distributor plate 3 and / or the mounting or mounting plate 2 another reed contact and / or a further reed contact and a further magnet may be provided. In principle, all parts of the casting mold can be used 1 of which it may be important to know if and when they are being developed.

2 schematically shows a plan view a distributor plate 3 a mold 1 with a further embodiment of the monitoring device according to the invention.

The distributor plate 3 has a heatable distributor 16 on which on the surface of the distributor plate 3 distributed valves 8th via appropriate channels 17 fed with liquid plastic. At the distributor 16 is a temperature sensor 21 provided with the temperature of the distributor 16 can be detected. The temperature sensor 21 is with a cycle counter 11 coupled, the same or similar as in 1 is constructed described.

If the mold 1 is in operation, the distributor points 16 a certain elevated temperature, which ensures that the plastic, with which the valves 8th be fed, is liquid. Like it out 1 is an expansion of the cycle counter 11 from the mold 1 only possible if the mold 1 not in operation. This is the result of the temperature sensor 21 at the distributor 16 temperature detected an indication of whether the mold 1 in operation or not.

By the cycle counter 11 with the temperature sensor 21 can be coupled through the cycle counter 11 Count values are assigned to a distributor temperature, so that ultimately can be decided whether the detected value during operation of the mold 1 or in a maintenance situation or the like has been detected. Only those counts correspond to wear-causing opening and closing cycles that occur during operation of the casting mold 1 have been recorded. Thus, by a corresponding adjustment of the values, incorrect counts of the cycle counter 11 be avoided.

In the 2 illustrated embodiment of the invention also has an outside of the mold 1 provided temperature sensor 22 on. The temperature sensor 22 measures a temperature outside of the mold 1 that differ from the temperature of the distributor 16 during operation of the mold 1 typically differs greatly, because the housing of the mold 1 is cooled during operation. Through the temperature sensor 22 can therefore be determined whether the cooling of the mold 1 is functional. In addition, at any point of the mold 1 , for example, with multiple distributors, outside of the mold 1 or close to the cavity of the mold 1 , further temperature sensors may be provided.

As in 1 is shown inside the case 12 of the cycle counter 11 an opening and closing cycle grouping and storing unit 23 intended. The opening and closing cycle grouping and storage unit 23 can be separate as well as within the signal acquisition and storage unit 25 of the cycle counter 11 be provided. In the opening and closing cycle grouping and storage unit 23 become the through the cycle counter 11 recorded count values in a basic time grid. The respective basic time can be set between one hour and one day depending on the respective casting mold. For each base time, the opening and closing cycle grouping and storage unit has 23 a separate counter. For each base time, there are six counters grouped by temperature. A first grouping takes place according to the location of the attachment of the temperature sensors 21 . 22 , Such is how it is in 2 is shown, for example, the temperature sensor 21 at the distributor 16 and the temperature sensor 22 outside on the mold 1 appropriate.

A second grouping of the counts takes place in temperature windows, the temperature windows one above, one below and below a temperature range lying between two limit temperatures include.

By providing a basic time grid and grouping the counts of the cycle counter 11 an information resolution takes place within the basic time grid. Thus, it can be determined, for example, how many shots there were in the respective basic time unit, for example in one hour, with normal, too low and too high temperature. This can save storage space.

In the case of conventional, in the operation of the mold 1 detected opening and closing cycles deviating events, such as a Kavitätsplattenzug, the counts of the cycle counter 11 specific times and exact temperatures are assigned and these are stored with the count.

By acting in the opening and closing cycle grouping and storage unit 23 is possible, that of the cycle counter 11 Registered values by grouping of values can be applied to the mold 1 executed actions and process steps are easily understood. For example, this makes it easier to clarify whether warranty claims against a manufacturer of the mold 1 exist or not.

By the outside of the mold 1 provided temperature sensor 22 can even if the mold 1 not in operation, the temperature of the mold 1 be recorded. This can, for example, during storage of the mold 1 be used, at which configurable times a temperature outside of the mold 1 detected and the respective measured value is stored in a memory. For example, when storing the mold 1 exceeded or exceeded a limit temperature, this can be done by the temperature sensor 22 conclusions can be drawn as to whether maintenance of the mold is necessary 1 , For example, an exchange of seals, is required.

The to the monitoring device according to the invention provided software can be designed in several stages. In The user receives a first, most comprehensive level Access to all data of the mold and this particular also delete and reset. According to a second Level of the software, all data of the mold are readable. In a third stage are only the production cycles of the mold readable, and in a fourth stage, the user can view the data Although read from the mold, but can not see. At this fourth Stage is only an encrypted record readable, which is then encrypted by other authorized persons. As a result, the manipulation security of the data set can be increased become.

Even though the above-mentioned monitoring device according to the invention with regard to molds, in particular injection molds described was, monitoring devices according to the invention, a counter in the form of a magnet and a reed contact as well as another reed contact, also for punching, Cutting and forming tools are used, which at least a tool part or a tool half, the on another tool part or another tool half is too mobile. It is also conceivable use of the monitoring device according to the invention in milling machining centers with movable tables.
