Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold which is convenient for demoulding. Background Art

[0002] In the process of making auto parts, molds are needed. Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry".

[0003] The patent document with the prior art publication number CN103286314A provides a mold for easy demoulding, including a lower mold and an upper mold, wherein the lower mold has an opening, and a groove is provided at the central position of the bottom of the opening of the lower mold, and a spring is placed vertically in the groove, and a top plate is provided at the upper end of the spring, and the shape of the top plate matches the opening. When the mold of the present invention is used to produce products, the powder is poured into the lower mold for compaction and the upper mold is covered. At this time, the top plate is pressed down to overcome the elastic force of the spring and is limited by the step at the bottom of the opening. After the powder is sintered and shaped, the upper mold is opened, and then the side wall of the lower mold is knocked, and the spring lifts the top plate to eject the product from the lower mold to complete demoulding. It can be seen that the present invention has a simple structure and low manufacturing cost; using the mold of the present invention for production, demoulding is convenient, production efficiency is improved, and the finished product can be ensured.

[0004] However, during the use of the existing mold, plastic is injected into the mold by using an injection molding device, and then the plastic is cooled. After cooling, the molded mold can be demolded. However, during the demolding process, the mold cannot be demolded automatically, resulting in low demolding efficiency, thereby affecting the problem of low production efficiency. For this reason, we propose a mold that is easy to demold. Utility Model Content
