Anti-overflow injection mold closing equipment with return guide function

Abstract

The invention discloses anti-overflow injection mold closing equipment with a return guide function. The equipment structurally comprises a heating hopper, a supporting block, a base and an extrusion pipe, the supporting block is fixedly embedded in the upper surface of the base, the extrusion pipe is connected with the front end of the supporting block, and the heating hopper is installed at the upper end of the supporting block; when molten plastic reversely extruded by the extrusion pipe generates thrust on a blocking mechanism, an external connection ring on the blocking mechanism can rotate clockwise along a connecting rod, so that a movement stopping block can be clamped on the side face of the connecting rod, and the external connection ring can be forced to stop rotating; and the situation that the molten plastic reversely extruded by the extrusion pipe can enter the heating hopper again is effectively avoided, a stress plate can rotate along a middle rod through reverse thrust generated by solidified plastic on the stress plate, and therefore an outer swing plate can be unfolded along the stress plate, and the solidified plastic can be smashed through the outer swing plate.

Description

technical field [0001] The invention relates to the field of equipment for injection mold clamping, in particular to an injection mold clamping equipment with a return function to prevent overflow. Background technique [0002] The anti-overflow injection mold clamping machine is mainly used for injection mold clamping of plastic raw materials. The plastic raw materials can be heated through the heating bucket, and then the molten plastic raw materials can be squeezed into the mold through the extrusion tube, and The overflowing molten plastic can be guided back inward through the extrusion tube. Based on the above description, the inventors have found that the existing injection mold clamping equipment with a return function to prevent overflow mainly has the following deficiencies, for example: [0003] Since the retrograde anti-overflow type injection molding machine returns the molten plastic through the extrusion tube, if there is a lot of molten plastic overflowing fro...

AI Technical Summary

Problems solved by technology

[0003] Since the retrograde anti-overflow type injection molding machine returns the molten plastic through the extrusion tube, if there is a lot of molten plastic overflowing from the mold, the molten plastic that is prone to return will squeeze the molten plastic inside the extrusion tube into the heated When the heating bucket heats the new plastic raw material again, the molten plastic extruded by the extrusion tube will be scorched by the heating bucket
