In Fig. 4, handle of Reference numeral 28 expression utilizes manual handle with air tight manner the cover cap 29 of heating container 22 to be carried out closure.In addition, Reference numeral 30 expression lift cylinders, this lift cylinders can realize the lifting of patrix 6 or with the clamping of predetermined clamping pressure to metal die 1.Reference numeral 31 expression positional cylinders, this positional cylinder is used to set up the predetermined location of battery cover cap 2 in the cavity 6 of the counterdie 5 of metal die 1.The direct driving mechanism of Reference numeral 32 expressions, this driving mechanism is used to control nozzle 23 and is connected with inlet 10 or separates with inlet 10.Specifically, directly driving mechanism 32 comprises a direct driving cylinder 33, a linear guide 34 and a slide block 35 that is used to install heating container 22.Reference numeral 36 expression is embedded in the temperature control of the heater 25 on the wall of heating container 22.
To be illustrated the metal die 1 of the preferred embodiments of the present invention and the working method of injection machine 21 below.
Directly direct driving cylinder 33 actions of driving mechanism 32 are moved slide block 35 backward, thereby make the nozzle 23 of heating container 22 leave the inlet 10 of metal die 1.Lift cylinders 30 action in addition promotes and separates with counterdie 5 patrix 6.
Then battery cover cap 2 and battery 3 are arranged in the cavity 9 of counterdie 5.Positional cylinder 31 actions then are that benchmark is set up predetermined location with the cover cap 2 in counterdie 5 cavitys 9.Therefore constitute cooling airflow path 14 by the dorsal part of battery cover cap 2 and the conduit 13 that on the bottom surface of counterdie 5 cavitys 9, forms.
After this, lift cylinders 30 counteragents are to the height of counterdie 5 directions reduction patrix 5.In case patrix 6 contacts with counterdie 5, guide finger 11 will be chimeric with pilot hole 18 respectively.Thereby will realize the interlocking of counterdie 5 and patrix, under predetermined fixing pressure, for example about 0.6 MPa realizes the fixing fully to metal die 1.
Under the fixing state of metal die 1, constitute cavity 19 by the cavity 9 of counterdie 5 and the cavity 20 of patrix 6.This cavity 19 is at battery cover cap 2, battery unit 3 and will fill between patrix 6 cavitys 20 of molten resin P and have predetermined space.In addition compressor 37 will cool off air present air-in 15 to the cooling.Be fed to the cooling air inflow of cooling air-in 15 and the cooling airflow path 14 of flowing through, constitute cooling air channels by the dorsal part of battery cover cap 2 and the conduit 13 that on the bottom surface of counterdie 15 cavitys 9, forms.The cooling air is taken away the heat on the battery cover cap 2 in the cooling air channels 14 of flowing through; Then cooling off air discharges by cooling air outlet 16.
In heating container 22, the resin of fusion is supercharged to a constant compression force by the work of booster 24.Under above-mentioned state, the valve of nozzle 23 26 is opened, thereby the resin P that makes the fusion that is pressurized 10 is injected in the cavity 19 of metal die 1 by entering the mouth.
Present embodiment adopts polyamide as resin material, and described polyamide is easy to realize at low temperatures fusion, and has low viscosity.The heater 27 of nozzle 23 is activated, thereby makes heating-up temperature be arranged on 200 ℃.Therefore the resin that is heated to the fusion of 200 ℃ of constant temperature can be fed in the cavity 19 of metal die 1.
The resin P that injects the fusion in metal die 1 cavity 19 will flow along the surface of battery cover cap 2, the dorsal part that is fixed on the battery cover cap in the cavity 9 of counterdie 5 carries out closure to the opening of conduit 13, so the resin P of fusion progressively is full of the space that is limited by battery cover cap 2, battery unit 3 and patrix 6 cavitys 20.In the space in molten resin progressively is full of the cavity 19 of metal die 1, the resin of fusion is progressively cooled off.After the resin P of fusion is full of the space of cavity 19 fully, begin sclerosis.
In filling the process of molten resin P, the certain zone that is positioned near the battery cover cap 2 the inlet 10 will be subjected to continuously flowing into by inlet 10 influence of resin P of fusion of the high temperature of cavitys 19 usually.This scope that is cover cap 2 will begin to finish to be heated for a long time to injection moulding from injection moulding.
Can avoid the 2 overheated and distortion of battery cover cap by the temperature that reduces molten resin P; The reduction of the Resin Flow that causes the fusion in metal die 1 cavity 19 but this names a person for a particular job.In contrast, present embodiment can be avoided the overheated of cover cap 2 and distortion, can not be reduced in the flowability of the resin P of the fusion in metal die 1 cavity 19 simultaneously again.Therefore, can avoid owing to molten resin P is not full of the molding flaw that the space of cavity 19 occurs fully.
The metal die 1 that adopts in the present embodiment injection machine 21 is made by aluminum with good heat-conducting or aluminum alloy materials.Therefore, the heat that is passed to battery cover cap 2 by molten resin P is passed through counterdie 5 by radiation, or the heat of molten resin P is by directly radiation or the diffusion of patrix 6 quilts.Thereby can avoid the overheated of battery cover cap 2 and battery unit 3.
Because the metal die 1 of present embodiment is made by aluminum or aluminum alloy materials.So the advantage of present embodiment is and can and makes metal die with very low cost processing.But, make the aluminum metal mould if only adopt to cut towards technology, then its shortcoming is, because the adhesive performance of metal die and resin is enhanced, thereby very difficult the good product of molding is carried out the demoulding.For overcoming this deficiency, the present embodiment suggestion is to the surface range of selecting at least of the metal die that directly contact with molten resin P during the injection moulding sandblast processing or chemical treatment.Be that the selected surface range (for example internal face of patrix 6 cavitys 20) of metal die 1 has and handles by sandblasting or that chemical treatment forms is small concavo-convex, the wherein small concavo-convex whole contact zone that will help to dwindle between resin and metal die 1 surface range, and can not impair ability to the layered product demoulding.
Owing to taked small concavo-convex measure is set, thereby resin and metal die 1 only be mutually adhered together the part, so can avoid power excessive when the demoulding to be added on the layered product.In addition, during the injection moulding with metal die 1 on the small concavo-convex resin surface that contacts on will form so-called wrinkle figure automatically.This names a person for a particular job and helps to improve the structural quality of resin.
As mentioned above, present embodiment is characterised in that to have the pressure-air cooling system that is used for the metal die 1 that is made of aluminum, and this names a person for a particular job and helps to improve heat radiation and thermal diffusion.In the front of metal die 1 inlet 10, heater 27 is arranged near the filled opening of nozzle 23 and by electrical control, and the resin P of fusion is heated to stationary temperature.Therefore the resin P of fusion can be presented to common metal die 1 under the uniform temp condition.This point is easy to make metal die to utilize cold wind to realize identical cooling work.Therefore can repeat and produce constantly battery with same quality.
After battery cover cap 2 and battery unit 3 were arranged in the metal die 1 fully, when counterdie 5 sent cold wind, the resin P that is heated to the fusion of steady temperature at preset time in the cycle was injected in the metal die 1 in compressor 37 work.Then, valve 26 closures of nozzle 23 stop to inject the resin P of fusion to metal die 1.After this, directly driving mechanism 32 is started working, and slide block 35 is moved backward, thereby make nozzle 23 leave the inlet 10 of metal die 1.In the case, send cold wind to counterdie 5 continuously, cold wind is flowed through incessantly and is cooled off airflow path 14.After the resin P of fusion hardened the required time cycle fully, compressor quit work, and stopped to send cold wind to the counterdie 5 of metal die 1.In addition, lift cylinders 30 startups promote patrix 6, make it to separate with counterdie 5.Then will make at the good battery 4 of cavity 9 inner mold of counterdie 5 utilizes above-mentioned pusher (not shown) to take out.
Owing to during the resin P of fusion injection metal die 1, battery 4 is effectively cooled off by the circulation of cold wind, therefore can't make battery overheated owing to the resin P of the fusion of high temperature, so can produce battery 4 reliably, and can not cause the distortion of battery cover cap 2.It is to be noted especially, be arranged on the inlet 10 near and in the specific scope of the battery cover cap 2 under the hot conditions effect during the injection moulding, can not occur substantially the distortion.Not only 2 of battery cover caps are cooled off during injection moulding effectively, and realize the cooling progressively of molten resin P by the middle battery cover cap 2 that inserts, so can't reduce its flowability.This point can guarantee that the resin of fusion is distributed in the angle and space that the internal face by battery cover cap 2, battery unit 3 and metal die 1 cavity 19 limits fully.So can produce the battery 4 that does not have the molding flaw.By taking in the predetermined surface scope of metal die 1, to form small concavo-convex measure, will improve the ability of the layered product or the resin demoulding according to present embodiment.When the demoulding, only need very little external force to be added on the battery 4.
In the present embodiment, adopt polyamide as resin material, described polyamide is easy to realize fusion at low temperatures and have low viscosity.The thermoplastic resin material that also can use other substitutes polyamide.Can also set corresponding shape, the degree of depth and the size of the conduit 13 of cooling air stream in addition.In addition, the position of conduit 13 needn't be limited to the position of above-mentioned neighboring entry 10.
Certainly, handle and chemical treatment also can be adopted any selected method small concavo-convex of formation on the inner surface section of metal die 1 except sandblasting.
The present invention can be widely used for adopting resin material to realize the integral body combination of housing and inner part thereof.Be battery cover cap 2 and battery unit 3 as housing and inner part thereof in the present embodiment.Certainly the present invention is not limited on the present embodiment; So can adopt other housing and inner part and resin-bonded to be integral realization the present invention.
