Precision injection mold

Abstract

The invention discloses a precision injection mold, which comprises an upper mold, a lower mold, a heating rod, a bolt hole, a positioning hole, a telescopic column, a baffle, a buffer layer, a damping spring, an asbestos layer, perforations, a lower mold cavity, and an upper mold Cavities, limit posts, coil springs, fastening bolts, connecting plates, top plates, bottom plates and mounting holes. The beneficial effects of the present invention are: by connecting the baffles on both sides of the upper mold and the lower mold, and filling the elastic buffer material between the two mold bodies and the baffles, and installing shock-absorbing springs and telescopic columns, the working baffles The two phantoms can be protected from damage. During transportation or handling, when the mold collides or is squeezed, the two mold bodies and the mold cavity inside are not easily damaged and deformed, ensuring that the mold can work safely and efficiently without easily affecting its precision. The injection mold is convenient and quick to install, saves energy, and has high work safety performance and precision performance.

Description

technical field [0001] The invention relates to an injection mold, in particular to a precision injection mold, which belongs to the application field of injection molds. 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. Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. In order to make the product size more accurate, precision injection molds are often used to make products. [0003] However, existing precision injection molds still have some deficiencies in use. The existing precision injection mold has complex internal structure, simple external structure, poor heat insulation abilit...

Problems solved by technology

[0003] However, the existing precision injection molds still have some deficiencies in use

Existing precision injection molds have complex internal structures, simple external structures, poor heat insulation, internal heat is easily lost, wasting energy, and staff are easily injured when working

The protection ability of the mold itself is poor, and it is easy to be damaged by impact, extrusion, etc. during transportation, and it is easy to deteriorate the precision of internal parts
