Push plate ejection demoulding and device

Push plate demoulding mechanism does not need the return rod reset. The push plate shall be oriented and positioned by the guide mechanism of the die to prevent excessive wear and offset between the push plate hole and the core.

Structure of push plate

The structure of push plate is a typical release mechanism of push plate. The push plate is driven forward by four push rods of the die, and the plastic parts are removed from the core. Push plate demoulding mechanism does not need another reset rod. Push plate is pressed back to its original position when clamping, and the push rod and push plate are reset accordingly. When pusher plate moves forward, it needs reliable support. Generally, there are four guide holes on pusher plate to cooperate with four guide pillars of the die and slide on the guide pillar. The pushing distance should be considered when designing the length of the guide pillar. The front end of the push rod can be flat and not connected with the push plate. It can also be processed into threads at the front end or connected with the push plate by means of screw, etc. In this way, it can prevent the sliding from the guide pillar due to the inertia of motion when pushing the part, or when the empty die is opened and closed, it will adhere to the fixed die edge and fall. When the push rod and the push plate are connected by threads, they can be guided by the support of the push rod itself, rather than by the guide pillar of the die.

For thin containers, shells and products whose surface is not allowed to have ejection marks, it is necessary to use a push plate to form an ejection ejection ejection mechanism. The main characteristics of the ejector demoulding mechanism are that the ejector demoulding force is large and uniform, the movement is balanced and stable, and no reset device is needed.

Generally, the pushing plate and the pushing rod can be omitted in proper time to save the pushing space of the die, so that the height of the die will be greatly reduced and the structure will be simplified. At the same time, because the moving die pad can directly contact with the moving template of the injection machine, the bending deformation of the pad will not occur, and the thickness of the pad can be significantly reduced.

When calculating the thickness of push plate, it will cause deflection due to insufficient stiffness of push plate, which will affect the dimensional accuracy of plastic parts. Therefore, the thickness of push plate should be calculated according to the stiffness condition.

Push plate for cylindrical plastic parts.

The pushing plate is usually driven by several pushing rods with concentric circumference distribution. The force acting on the pushing plate during demoulding can be regarded as the mechanical model of the annular plate under concentrated load, and the maximum deflection occurs in the center of the plate.

Push board for rectangular plastic parts.

When ejecting, the force acting on the pushing plate can be regarded as a simply supported beam model under concentrated load, and the maximum deflection occurs in the center of the plate.
