Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a plastic toy injection mold. Background Art

[0002] Plastic toys are toys mainly made of plastic. According to the plastic molding process, they are divided into injection-molded toys, blow-molded toys, rotomolded toys, slush-molded toys, inflatable toys, etc. Among them, injection-molded toys are formed by injecting the raw materials heated into a liquid state by an injection molding machine into a mold and then cooling. Therefore, injection molds can be used to make plastic toys.

[0003] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) The existing utility model plastic toy injection mold lacks holes for injection and exhaust that can be opened synchronously. In order to exhaust air, the sealing performance of the mold becomes poor. During injection molding, air runs out from the joint at the edge of the mold, resulting in the injection raw material also flowing into these gaps. After the plastic toy is formed, there will be a large amount of excess plastic at the edge of the toy, increasing the workload of subsequent edge grinding of the plastic toy and also increasing the waste of raw materials.

[0006] (2) The existing utility model plastic toy injection mold lacks an ejection mechanism. When demolding the plastic toy, it is necessary to manually pick out the plastic toy from the mold base, which easily causes deformation and damage to the plastic toy and has low work efficiency. Summary of the Utility Model

[0007] The technical problem to be solved by the present utility model is to overcome the above technical defects and provide a plastic toy injection mold with strong sealing performance, convenient for exhaust during injection molding, and capable of quickly ejecting the plastic toy for complete demolding.
