Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a plastic mold for a decorative cover which is convenient for cooling and molding. Background Art

[0002] A decorative cover is a cover used to decorate and protect specific items. It is usually made of metal, plastic or other materials and has multiple uses and functions. There are many types of decorative covers, and water pipe decorative covers are an important component. They are used to decorate wall water pipe outlets and are mostly made of plastic injection molding. Therefore, a decorative cover plastic mold that is easy to cool and mold is used during production.

[0003] Traditional decorative cover plastic molds generally use air cooling and water cooling to cool the injection mold. However, air cooling speeds up the air flow rate outside the injection mold, causing the mold to gradually cool down from the outside to the inside, resulting in low heat dissipation efficiency. Water cooling is achieved by fixing a ring or other shaped water pipe inside the lower mold base. When the cooling water flows through the water pipe, it absorbs the heat inside the mold. However, the water flow rate will cause the cooling water to not fully absorb the heat and will be discharged. In addition, scale is easily accumulated on the inner wall of the water pipe. The contact area between the cooling water and the mold is only the inner wall of the water pipe. Therefore, there will also be problems with heat dissipation efficiency. At the same time, scale that is difficult to clean will further reduce the heat dissipation efficiency. Utility Model Content

[0004] The utility model aims to provide a decorative cover plastic mold which is easy to cool and mold, so as to solve the defects of the existing decorative cover plastic molds, such as low heat dissipation efficiency and difficulty in cleaning scale.

[0005] In order to solve the above technical problems, the present utility model provides the following technical solutions: a plastic mold for a decorative cover that is convenient for cooling and forming, comprising a base;

The first fixing seat is installed on the outer walls on both sides of the top of the lower mold seat by bolts, and the second fixing seat is installed on the outer walls on both sides of the bottom of the upper mold seat by bolts. A clamping seat is evenly provided on one side of the second fixing seat, and a connecting seat is fixed at one end of the clamping seat. A fixing pin is passed through the inside of the connecting seat, and a compression spring is sleeved on the outside of the fixing pin at the top of the connecting seat, and a fixing block is fixed on both sides of the clamping seat away from one end of the connecting seat.
