Apparatus for pulling core through ejecting block in small space

Abstract

The present invention belongs to the field of machinery manufacturing, and relates to an apparatus for pulling core through an ejecting block. The apparatus comprises a straight ejecting block, a fixed T-shaped block, a T-shaped core pulling block, an ejecting block linking rod, an ejecting plate, an ejecting plate fixation plate and the like so as to achieve the core pulling action in a small space. According to the present invention, the equipment investment is low, the mold achieves the core pulling in the small space, the structure is simple, the ejecting can be completed in the conventional mold ejecting structure, the operation is simple, the production cost is low, the reliability is high, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing and relates to a core-pulling device for jacking blocks in a narrow space. Background technique [0002] For a space of 15.2mm, it is almost impossible to use an inclined top block to achieve core pulling. The material of this product is ABS, and there is no appearance part. The reinforcement ribs cannot produce sink marks on the outer surface. The wall thickness of the product is 2.75mm, and the thickness of the reinforcement ribs It is 0.9mm, so that no sink marks will be produced, but the thickness of 0.9mm is not enough to have sufficient strength. Remove the connection with the main surface and increase the wall thickness of the reinforcement, thereby producing the undercut of the reinforcement, such as figure 2 The shown core-pulling structure is completed in a narrow space to pull the core. In actual production, the designed core-pulling structure is simple, low in cost, easy to oper...

Problems solved by technology

[0004] The core-pulling feature of the top block is that it is composed of a movable mold, a T-shaped fixed block, a T-shaped core-pulled block, a straight top block, bolts, a straight top block connecting rod, a top plate, a top plate fixed plate, etc., and the core-pulling space is only 15.2 In the case of mm, there are two problems in the design of the inclined top block: 1. The thickness of the inclined top block is very small, that is, the strength is not enough; 2. In the space of 15.2mm, there is insufficient space for the movement of the inclined top block. Designing this structure will solve this problem two questions
