An injection mold for processing products with oblique holes

Abstract

The invention provides an injection mold for processing a product with an oblique hole, and belongs to the technical field of molds. The injection mold comprises a fixed mold middle plate, a movable mold middle plate and a movable mold seat plate, wherein an injection molding cavity for forming a product with an oblique hole is formed by buckling the fixed mold middle plate and the movable mold middle plate; a pushing assembly is movably mounted between the movable mold middle plate and the movable mold seat plate; a straight ejection block connected with the pushing assembly is embedded into the movable mold middle plate; a mounting slot is formed in the straight ejection block, and an inclined core pulling needle is mounted in the mounting slot; a resetting piece sleeving the core pulling needle is also mounted in the mounting slot; during mold assembling, one end of the core pulling needle penetrates through the straight ejection block and is inserted into the oblique hole of the product, and the other end of the core pulling needle is pressed against the movable mold middle plate; during mold opening, the pushing assembly upwards ejects the product and simultaneously drives the straight ejection block to move upwards; at the moment, the resetting piece works and drives the core pulling needle to be separated from the oblique hole of the product. The injection mold has the advantages of simple structure, high working efficiency and convenience in maintenance.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a mould, in particular to an injection mold used for processing products with oblique holes. Background technique [0002] Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and melted materials into a mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. At present, my country's economy is still in the stage of rapid development, and the international trend of economic globalization is becoming more and more obvious, which provides good conditions and opportunities for the rapid development of my country's mold industry. On the one hand, the domestic mold market will continue to develop at a high speed. On the other hand, mold manufacturing is gradually shifting to my country and the trend of multinational groups purchasing molds in my coun...

Problems solved by technology

The design of the above-mentioned cylinder-type core-pulling mold is unreasonable, and has the following defects: first, the structural layout is relatively complicated and difficult to process, and installation and disassembly are relatively cumbersome; 3. When the mold is produced, the oil cylinder and push block must be pulled out first to realize the mold opening work and eject the product. After the mold is closed, it is necessary to control the oil cylinder again to push the push block into the core-pulling gap, and then close the mold The core can be reset only after the core of the oil cylinder is pulled, so as to prevent the core-pulling pin of the oil cylinder from hitting the cavity surface, which will bring certain risks to the mold production operation, and the working process is relatively cumbersome, which reduces the work efficiency
