Auxiliary assembly device based on installation of small injection mold

Abstract

The invention discloses an auxiliary assembly device based on installation of a small injection mold and relates to the technical field of auxiliary assembly devices. The problem that a punching needle plate is easy to damage due to low precision because most of existing punching needles are manually operated during assembly is solved. The auxiliary assembly device based on installation of the small injection mold comprises a kinetic energy block. The kinetic energy block is connected to a rod body at the top of a hammering rod in an inserted manner. The device is high in automation degree, the hammering rod can be controlled to hammer the punching needles only by pressing a pressing rod in a reciprocating manner, under the positioning effect of a positioning plate and a positioning hammer, the punching needles are hammered accurately, the punching needles can be assembled on a punching needle plate accurately, the positioning plate and the positioning hammer have various matching combinations, the device can meet the installation requirements of different punching needles, the adaptability is high, and the practicability and the adaptability of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary assembly devices, and more specifically relates to an auxiliary assembly device for installation based on a small injection mold. Background technique [0002] Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". Wherein, the assembly of the punching pin and the punching pin fixing plate is generally a zero-fit assembly or an interference fit assembly. [0003] For example, in the patent with the application number: CN201410...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides an auxiliary assembly device based on the installation of small injection molds to solve the problem that the existing punching pins are mostly manually operated when assembling. Knocking the needle into the fixing hole of the punching needle fixing plate to fix it, the labor intensity is high, the precision is low, and the hammering direction is likely to be deflected, so when the punching needle is knocked into the fixing hole of the punching needle fixing plate, it is easy to break the punching needle and the The edge of the fixing hole in the punching needle fixing plate is roughened, and the fixing hole in the guide column punching needle fixing plate becomes larger. Seriously, the phenomenon of scrapping the punching needle fixing plate will occur, and the practicability is not high.
