Description

Technical Field

[0001] The utility model relates to the technical field of plastic part molding, in particular to a waterproof molding structure of a plastic part. Background Art

[0002] Plastic raw materials are defined as synthetic or natural high molecular polymers that can be arbitrarily molded into various shapes and can finally maintain the same shape. Therefore, they will be widely used in waterproof plastic parts. In the process of plastic part injection molding, a waterproof molding structure of plastic parts is needed to make the production of the plastic parts more convenient and quick.

[0003] In the prior art, when it is used, the staff is required to clamp and fix the mold and confirm whether the mold is in a sealed state before injection molding production can be carried out, which makes the work efficiency low. After the injection molding is completed, the staff is required to manually separate the mold after the plastic parts are formed, which makes it time-saving and labor-saving to take the plastic parts, but it is more time-consuming and labor-intensive for the staff. In addition, the device has poor stability during the injection molding process. If shaking occurs, defective products are likely to appear when the plastic parts are molded. Therefore, we propose a waterproof molding structure for plastic parts. Utility Model Content
