Description

Technical Field

[0001] The utility model relates to the field of plastic molds, in particular to a sealing and isolating part mold. Background Technique

[0002] Under the guidance of the concept of social sustainable development, protecting resources and utilization, reducing the pressure on natural and social resources, reducing the damage to the natural ecological environment, and reducing the waste of human resources are the key issues of industrial production. Therefore, an optimized design of the structure of this isolation mold part is carried out.

[0003] In the existing technology, although injection molding of plastic products can be achieved during use, there are defects: the exhaust inserts of the existing sealing and isolating mold products are relatively thin and small, and it is not easy to fill the injection molding. Due to the air entrapment problem, the exhaust inserts are prone to small flash problems at the position of the U-shaped groove. In view of this, we propose a sealing and isolating part mold to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a sealing and isolating part mold for the problems existing in the background technique.

[0005] The technical solution of the utility model: a sealing and isolating part mold, including a lower mold body, an exhaust insert and an upper mold body. The upper mold body is fixed at the upper end of the lower mold body. On one side of the upper surface of the upper mold body, U-shaped grooves are arranged in a circular array, and exhaust inserts are installed on the surfaces of the U-shaped grooves;

[0006] When this device is in use, first fix the exhaust insert on the upper end of the U-shaped groove by means of a buckle, then press the injection molding device on the upper end of the upper mold body, and then carry out injection molding. After injection molding, move the injection molding device away, and then carry out demolding. Since this device improves the position of the U-shaped groove and enlarges the size of the exhaust insert so that it can cover the entire U-shaped tube, this can reduce the flash problem caused by exhaust and has high practicability.

[0007] Preferably, a forming groove is provided at the upper end of the upper mold body, and a baffle is fixed on the surface of the forming groove. The baffle can divide the surface of the forming groove into multiple regions. This is a special design of the mold shape and can be adapted to the company's exclusive plastic disc-shaped products.

[0008] Preferably, the baffle divides the forming groove into seven regions.

[0009] Preferably, a limiting column is fixed on one side of the U-shaped groove. The limiting column can assist in the position limitation during mold closing to prevent deviation problems.

[0010] Preferably, a buckle is fixed between the limiting post and the U-shaped groove. The exhaust insert can be fixed to the upper end of the U-shaped pipe by using the buckle to ensure the fixing effect of the position.

[0011] Preferably, a plurality of limiting blocks distributed in an annular array are fixed to the lower end of the lower die body. The limiting blocks can assist in fixing the lower die body on the surface of the injection molding device.

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] First, the present utility model enlarges the design size of the exhaust insert so that it can cover the entire U-shaped groove, which can reduce the fluidity of gas after mold closing and reduce the size of flash.

[0014] Second, based on the beneficial effect one, the position of the U-shaped groove of the original product has small flash, while the position of the U-shaped groove of the current product has no flash, and the production efficiency is further improved to meet the requirements of subsequent customers.

[0015] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS
