Processing method of car lamp mold base

Abstract

A machining method of an automobile lamp mold frame is characterized by comprising the steps of workpiece sawing, six-face rough milling, punching of a cooling water tube, punching of an ejecting rod hole, punching of other station holes, detecting of holes, large shape milling, splicing of a fixing plate, and finish milling. A plate material is milled first and then the hole drilling process of the cooling water tube is directly conducted. The structure of the plate material is simple, the six faces of the plate material are flat and smooth, the hole drilling process of the cooling water tube is convenient and fast to conduct, and the phenomenon that a wall face is damaged or abraded during hole punching due to the fact that the distance between the wall faces of staggered and rugged wall-shaped structures obtained by milling a large shape first and holes to be punched is avoided. More importantly, the cooling water tube and other holes are punched first, then the machining processes of large shape milling and finish milling are conducted. The plate material is milled first, the material is regular in structure, even multiple holes are machined in the material, the small deformation performance of the whole section material can be still guaranteed, the standard size of a formwork can be effectively guaranteed, and over deformation is prevented.

Description

technical field [0001] The invention relates to the technical field of mold base processing, in particular to a processing method for a vehicle lamp mold base. Background technique [0002] The mold base is a semi-finished product of the mold. It is composed of various steel plates and matching parts. It can be said that it is the skeleton of the whole set of molds. be valued. With the continuous growth of the automobile market, the shape and performance requirements of automobile lights are becoming more and more abundant and strict. However, most of the automobile lights are plastic products, and the main processing technology used is injection molding. Therefore, a good formwork structure design It is the prerequisite for the manufacture of a qualified injection molding product. The mold base structure and product structure need to be analyzed in all aspects, such as including: mold release slope, product surface miniature, gating system design, exhaust system design, co...

Problems solved by technology

[0003] The cooling system needs to be equipped with a large number of cooling water pipes, in addition to installation holes, positioning holes and ejector holes, etc. A complete set of car lamp molds is assembled from four mold bases, and each assembled mold base Both require multiple hole mechanisms inside. The traditional processing method is to first mill out the original shape of the raw material with a milling cutter, and then use electric spark or electric cutting to punch out the cooling water pipe; however, due to the complex structure of the car lamp, its mold base The structure of the formwork is also very complicated. For example, due to the complexity of the structure on the formwork board, the initial shape is milled first, and then when drilling, some holes will be very close to the wall, which is not easy to punch out, and will damage the wall. In addition, because the initial shape is milled first, and then drilled, the number of holes is large, which can easily lead to thermal deformation of the mold base, thus affecting the accuracy of the overall mold base
