Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a linkage demoulding structure of a four-way pipe mold. Background Technique

[0002] In the processing of injection molds, plastics are first added into the molds and then cooled and shaped. At present, some plastic shell parts are produced and processed through injection molds. These plastic shells have some complex structures, resulting in very difficult demoulding.

[0003] In the application with the patent publication number of CN215969816U, a linkage demoulding structure of a four-way pipe mold is disclosed, including a moving die core. The fixed template is located above the moving die core. The fixed template is provided with a first guide rail, a second guide rail and a third guide rail. A driving inclined groove is opened on the right slider of the inclined thin pipe. The right slider of the bent pipe is connected to the second guide rail and can move towards the molding part. A driving block is fixedly arranged on the left slider of the bent pipe. In this way, there is no need to set corresponding lifters or inclined guide posts, thus saving the space of the fixed mold.

[0004] However, since the four-way pipe is cross-shaped and is located in the molding part on the moving die core after injection molding of the four-way pipe, the first guide rail and the second guide rail can move the bent pipe part, so that the left and right sides of the four-way pipe can be demoulded. However, the through pipes on the left and right sides will be stuck in the molding part and are not easy to be completely demoulded. At the same time, due to the integral injection molding of the four-way pipe, the positioning of the moving die core with the bent pipe and the inclined thin pipe is inconvenient, resulting in poor injection molding quality and poor injection effect.

[0005] Therefore, we propose a linkage demoulding structure of a four-way pipe mold. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a linkage demoulding structure of a four-way pipe mold, which solves the problems of inconvenient demoulding and inconvenient positioning of the existing device.

On the left side of the right mold, four groups of inserting rods with matching specifications are fixedly installed. On the right side of the left mold core, a cross-shaped positioning block A is fixedly installed. On the left side of the right mold core, a positioning block B with a matching specification is fixedly installed. On the bottom surface of the upper mold core, a positioning hole B matching the specifications of the positioning block A and the positioning block B is opened.

On the bottom surfaces of the left mold and the right mold, sliding blocks A matching the specifications of the chute A are respectively and fixedly installed, which can improve the sliding stability of the left mold and the right mold.
