Injection molding mold assembly convenient to disassemble and assemble

Abstract

The invention relates to an injection molding mold assembly convenient to disassemble and assemble. The injection molding mold assembly includes a hot sprue, a front mold core and a rear mold core, the hot sprue is sleeved with the front mold core, the rear mold core is arranged on the lower side of the front mold core, a plurality of slide insert assemblies and a rear mold insert are arranged inthe rear mold core, the lower ends of the slide insert assemblies are provided with shovel bases and shovel base heel blocks, a mold product cavity is formed between the front mold core and the rear mold core, and the hot sprue allows molten plastic materials to be injected into an inlet inside the mold from a nozzle of an injection molding machine. The hot sprue is sleeved with the front mold core, so that the occupied space is reduced; the hot sprue is arranged in a three-section manner, meanwhile, fixed connection with the front mold core is achieved, and disassembly, assembly, maintenanceand repairing are facilitated. Meanwhile, the hot sprue is matched with a hot sprue hole through threads, so that quick disassembly and assembly are achieved, and the structure is compact. In cooperation with the shovel bases and the shovel base heel blocks, the bottom is more stable, all elements adopt a convenient-to-disassembly connecting manner, and washing and maintaining are facilitated.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold assembly that is easy to assemble and disassemble. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc...

AI Technical Summary

Problems solved by technology

[0006] Existing injection molding mold components have complex structures, many layers, and complex structures, which are inconvenient for long-term maintenance and repairs and regular cleaning, and the current injection molding mold components are difficult to demould due to unreasonable structural settings.
