Abstract
The utility model provides a special simple efficient mechanical protection device for an injection moulding machine. A safety rod of the device is articulated with a movable mould plate through a safety rod fixing shaft; meanwhile, through the support of a safety rod limiting shaft, the safety rod is suspended below a flashboard and is separated from any other parts of the machine, so that the frictional abrasion of a safety ruler is eliminated in the daily movement; due to the adoption of the ratchet wheel and pawl principles, the opening/closing direction of the flashboard and the moving direction of a mechanical lock rod are on the same plane; a rotating shaft serves as both a flashboard rotating shaft and a bearing shaft and does not carry lateral pulling force; and the flashboard is mainly pressed. The safety coefficient of a mechanism is improved, so that the requirements of the special simple efficient mechanical protection device for simplicity and efficiency of a mechanical safety device can be achieved by changing the design of a mechanical structure.
Description
Affiliated technical field
The utility model relates to the special-purpose simple and efficient Machine guarding of a kind of injection machine.
Background technology
Traditional injection machine Machine guarding generally is to adopt two kinds of structures: first kind is that safety axle one end is fixed on two plates through screw device, and the other end cooperates with flashboard on being fixed on tailgate or frame through the tailgate via hole, through the keying of gate driving flashboard; Second kind is that safety axle one end is hinged on two plates through pin shaft device, and the flashboard on the other end receives independent seat supports and is fixed on independent bearing or frame cooperates, and drives flashboard through gate and opens and closes;
There is following problem in aforementioned first kind of structure: 1) assembling and use, because the fluctuation of the processing of safety axle, transportation, storage condition usually causes assembling back safety axle and tailgate via hole interference friction, reduce and guarantee device safety coefficient and service life; 2) at the distortion of complete machine useful life Nei Changyin screw thread, rust extremely, cause the safety axle to be difficult to safeguard.
There is following problem in structure in aforementioned second: the safety axle is hinged with two plates, because gravity, there is serious sliding friction in the safety axle with independent bearing,, expensive wear-resistant device need be set or often change wear parts in the time limit at machine life.
Summary of the invention
The utility model technical problem to be solved: provide a kind of injection machine special-purpose simple and efficient Machine guarding; The safety pole of this device is hinged through safety pole fixed axis and moving platen; Simultaneously; Safety pole passes through the support of safety pole limit shaft, is suspended at below the flashboard and with other any parts of machine to break away from, and has eliminated the fretting wear of safe chi in daily exercise; Adopt the click principle, make the direction of motion that flashboard opens and closes direction and mechanical locking bar on same plane, rotating shaft be the flashboard rotating shaft be again reach, and do not bear side direction and pull power, the main pressurized of flashboard.Improved mechanism's safety coefficient, thereby realized making it reach the requirement of mechanical safety device simple and efficient through the design that changes frame for movement.
The utility model solves the technical scheme that its technical problem adopts: a kind of Machine guarding of injection machine, and it comprises independent bearing, rotating shaft, flashboard, flashboard gripper shoe, bearing, screw, safety pole, safety pole fixed axis, safety pole limit shaft; Install the DU sleeve bearing additional between described independent bearing and the rotating shaft; Described independent bearing, rotating shaft, flashboard, flashboard gripper shoe, bearing, screw assembling back form the mechanical position limitation part; Described safety pole, safety pole fixed axis, safety pole limit shaft assembling back form the matched moulds double-action part, and safety pole is hinged through safety pole fixed axis, safety pole limit shaft and moving platen, is suspended at the flashboard below.
The beneficial effect of the utility model:
1. the device of utility model adopts the click principle, the keying direction that makes flashboard and the direction of motion of mechanical locking bar on same plane, rotating shaft at this moment be the rotating shaft of flashboard be again reach, and the power that side direction is pullled is no longer born in rotating shaft; When playing safeguard protection, this device does the time spent, the rapid and mechanical engages of the flashboard assembly of this design ability under deadweight, and protective reaction is fast; Because of the main pressurized of flashboard, deflection is little again, and security performance is higher.
2. safety pole is suspended in by the independent bearing under the safety limit shaft supports, and does not contact with bearing and other parts contact of machine; Eliminate mechanism's fretting wear in use; Improve mechanism's safety coefficient, prolong mechanism service life, thereby effectively prolong complete machine service life.
3. all load bearing components all use a part in the device, reduce to produce materials, also make produce, install, safeguard convenient.

The specific embodiment
As shown in Figure 1; The special-purpose simple and efficient Machine guarding of a kind of injection machine, it comprises independent bearing (1), rotating shaft (2), flashboard (3), flashboard gripper shoe (4), bearing (5), screw (6), safety pole (7), safety pole fixed axis (8), safety pole limit shaft (9).Install the DU sleeve bearing additional between described independent bearing (1) and the rotating shaft (2), rotating shaft (2) two ends are provided with the mechanical position limitation structure; Described independent bearing (1), rotating shaft (2), flashboard (3), flashboard gripper shoe (4), bearing (5), screw (6) assembling back form the mechanical position limitation part; Described safety pole (7) is hinged with moving platen through safety pole fixed axis (8), safety pole limit shaft (9), is suspended at the below of flashboard (3); Described safety pole (7), safety pole fixed axis (8), safety pole limit shaft (9) assembling back form the matched moulds double-action part; Described safety pole fixed axis (8) arranged outside mechanical stop limiter.
Operation principle:
This contrive equipment adopts click principle: when gate is closed to design attitude, gate hits plate and lifts bearing (5) and drive flashboard (3) and lift, and safety pole (7) drives down and can below flashboard (3), move freely at moving platen; When gate leaves the design safety position, gate hits plate and bearing (5) is thrown off, flashboard (3) under the self gravitation effect, around the shaft (2) rotate with safety pole (7) on the step interlock locked, thereby stop the motion of moving platen matched moulds to play the safeguard protection effect.
Claims (1)
1. the special-purpose simple and efficient Machine guarding of an injection machine, it is characterized in that: it comprises independent bearing (1), rotating shaft (2), flashboard (3), flashboard gripper shoe (4), bearing (5), screw (6), safety pole (7), safety pole fixed axis (8), safety pole limit shaft (9); Install the DU sleeve bearing additional between described independent bearing (1) and the rotating shaft (2); Described independent bearing (1), rotating shaft (2), flashboard (3), flashboard gripper shoe (4), bearing (5), screw (6) assembling back form the mechanical position limitation part; Described safety pole (7), safety pole fixed axis (8), safety pole limit shaft (9) assembling back form the matched moulds double-action part, and safety pole (7) is hinged with moving platen through safety pole fixed axis (8), safety pole limit shaft (9), is suspended at flashboard (3) below.
