Embodiment 1

[0035] This embodiment provides a multi-directional core-pulling injection mold for spherical skeleton parts, which is mainly designed with a two-plate mold, wherein the mold base adopts the Long Kee Dashuikou mold base standard; the core and the cavity insert adopt a self-designed polyhedron shape; The core-pulling structure adopts the hydraulic cylinder side core-pulling method; the core cavity and the formwork are connected and fixed by bolts, and both of them adopt the positioning form of the boss groove; the pouring system design adopts the latent gate; the ejection scheme adopts the The cylinder is ejected; the cooling method is water cooling, and the drilling and processing of the water channel is used in the movable and fixed mold inserts for mold cooling; the mold exhaust system adopts the form of mold clearance and side core-pulling clearance exhaust.

[0036] The movable and fixed model cavity is divided by the broken line parting surface, and the cavity insert and t...

Abstract

The invention discloses a multidirectional core-pulling injection mold for spherical framework parts. The multidirectional core-pulling injection mold comprises a fixed mold plate, a movable mold plate and a sprue bush, a fixed mold mounting plate is arranged on the upper portion of the fixed mold plate, a fixed mold main core is mounted in the fixed mold plate and connected with a fixed mold sidecore-pulling structure, the movable mold plate is arranged on the lower portion of the fixed mold plate, and a movable mold main core is mounted in the movable mold plate and connected with a movablemold side core-pulling structure. Multi-angle, multi-directional and different-sequence side core-pulling movement is achieved on the premise of use of universal plastic molds and formworks, so thata hollow framework product is molded and formed once.

Description

technical field [0001] The invention relates to an injection molding mold structure, in particular to a multi-directional core-pulling injection mold for spherical skeleton parts. Background technique [0002] Plastic is a new type of material invented at the beginning of the last century. After a long period of development, it has become one of the indispensable materials in human daily life. The development of plastic processing technology has also started since then. At present, the main plastic processing technologies include injection molding, extrusion, calendering and so on. Among them, the injection molding process is widely used in processing various parts. [0003] At present, the vast majority of plastic mold structures are mainly three-plate molds and two-plate molds. In these two mold structures, due to the difference in cavity structure, some structures may be inconsistent with the mold opening direction, or even interfere with mold opening. Therefore, the la...
