Preparation technology of detachable welding type mold insert (core)

Abstract

The invention relates to a preparation technology of a detachable welding type mold insert (core). Steels after being quenched are adopted steels of moulds of an A flitch and a B flitch of a processing mold insert, and water ways are accurately processed and distributed according to a product structure and a mould structure so as to rapidly cool a product, thereby increasing the efficiency; the A flitch and the B flitch can also adopt steels of different material quality, wherein the A flitch adopts a material with high stability and thermal conductivity, and the B flitch adopts a material with good processability; the A flitch and the B flitch after processing are specially welded so as to enable the A part and the B part to reach an integral state. The invention eliminates the deficiencies of the prior art, increases the processing efficiency, reduces the processing difficulty and increases the qualification rate of a finished product.

Description

technical field [0001] The invention belongs to the field of mold manufacturing, in particular to a preparation process of a split welding mold kernel (core). Background technique [0002] At present, the molds used in the fields of automobiles and precision machinery equipment are mainly precision plastic molds. This kind of mold is a complex and compact mold, which has high requirements for materials, precision and cooling temperature. The preparation process of the mold core (core) of the existing precision plastic mold is blanking→watering→heat treatment (quenching)→finishing. The disadvantages are: 1. The mold core (core) is made of a whole mold material, and its All the cooling waterways are processed before heat treatment (quenching) of the raw materials. Due to the independence of the cooling waterways, they cannot interfere with other parts of the mold core. They are all processed before heat treatment, and the distance between the waterway and the waterway or other...

Problems solved by technology

The preparation process of the mold core (core) of the existing precision plastic mold is blanking→watering→heat treatment (quenching)→finishing. The disadvantages are: 1. The mold core (core) is made of a whole mold material, and its All the cooling waterways are processed before heat treatment (quenching) of the raw materials. Due to the independence of the cooling waterways, they cannot interfere with other parts of the mold core. They are all processed before heat treatment, and the distance between the waterway and the waterway or other surface parts is very small. It is processed by a drilling machine. , so it can only be processed into straight-line holes. For straight-line holes with three-dimensional intersections, it is easy to break the position with a drilling machine. At the same time, the requirements for processing equipment and tools are relatively high; The cooling time of the parts is different, which makes the opening and closing time longer and the efficiency is low; 3. The processing and production of the existing mold kernel (core) is relatively difficult, the processing cycle is long, and the scrap rate is high
