Multi-stage sectional type automatic ejection mold for producing IPM power module

Abstract

The invention belongs to the technical field of power electronic power module production, and provides a multi-stage sectional type automatic ejection mold for producing an IPM power module. The mold comprises an upper mold plate provided with an upper mold cavity, a lower mold plate provided with a lower mold cavity, a mold cavity, a first demolding mechanism and a second demolding mechanism, a mold insert is arranged in the lower mold cavity, and a lower mold base is arranged below the lower mold plate. The mold cavity is formed by splicing the mold insert, the upper mold cavity and the lower mold cavity, and the mold cavity is used for injection molding of the IPM power module. The first demolding mechanism is arranged between the lower mold base and the lower mold plate and is used for demolding the IPM power module formed by injection molding out of the multi-stage sectional type automatic ejection mold. The second demolding mechanism is arranged between the first demolding mechanism and the lower mold plate, and the second demolding mechanism is used for demolding the mold insert out of the multi-stage sectional type automatic ejection mold. Compared with the prior art, the mold has the advantages that the production procedures of products are reduced, the automation degree and the production efficiency of production are improved, and the production quality of the IPM power module is improved.

Description

technical field [0001] The invention belongs to the technical field of power electronic power module production, and in particular relates to a multi-stage segmented automatic ejection mold for producing IPM power modules. Background technique [0002] Power electronics technology occupies a very important position in today's fast-growing industrial field. As a representative of power electronics technology, power electronics power modules have been widely used in electric vehicles, photovoltaic power generation, wind power generation, industrial frequency conversion and other industries. With the rise of my country's industry, power electronics power modules have a broader market prospect. At present, power electronic power modules are gradually developing in the direction of integration and intelligence, and IPM modules emerge as the times require. Compared with the standard power module, the IPM module adds an additional control and evaluation logic unit, which is integr...

Problems solved by technology

[0004] Among them, using tools to separate the IPM power module from the mold insert may cause damage to the plastic body of the casing and crush the plastic body of the casing, resulting in a low production yield, and the generated debris will remain on the casing, making it difficult to clean , which seriously affects the binding wire, and even causes expensive parts to be scrapped, and the production process of the entire IPM power module is complicated, the production efficiency is low, and the automation level of production is reduced
