Embedded type pulling core used by automobile door lock sleeve die-casting die

Abstract

The invention discloses an embedded type pulling core used by an automobile door lock sleeve die-casting die. The embedded type pulling core comprises a main sliding way, wherein an embedded slide groove with a certain angle is formed in one side of the main sliding way, an embedded pulling core slide block is connected into the embedded slide groove, and a bottom hole core is fixedly connected toone side of the embedded pulling core sliding block; and a pit pulling core sliding block is arranged on one side of the embedding sliding groove, close to the bottom hole core, of the pit pulling core sliding block, and a pit pulling core 1 is arranged on one side, close to the bottom hole core, of the pit pulling core sliding block, an auxiliary guide rod is arranged on one side, close to the embedded pulling core sliding block, of the pit pulling core sliding block, an included angle of 35 degrees is formed between the auxiliary guide rod and the sliding direction of the pit pulling core sliding block, and a guide rod hole matched with the auxiliary guide rod is formed in the embedded pulling core sliding block. By means of the embedded pulling core design, the structure of the part issimplified, the consistency of design, process and product assembly is guaranteed, and large-scale batch production is facilitated.

Description

technical field [0001] The invention relates to a die-casting mold for an automobile door lock cover, in particular to an embedded core-pulling used in the die-casting die for an automobile door lock cover. Background technique [0002] In the structural design of die-casting molds, there are many structures such as dynamic and fixed mold cavities, slider core-pulling, embedded inserts / inserts, etc., and the specific application of embedded core-pulling has not yet been seen. [0003] The door lock sleeve described in this patent is a zinc alloy die-casting, and its structure is as follows: Figure 1-3 As shown, the enlarged picture of point I is shown in Figure 4 shown. Depend on Figure 1-4 It can be seen from the structure diagram of the part that there is a 5°±30’ installation different-plane datum on the part, and at the same time in the direction of 55°±30’, the part has a bottom of φ4.5+0.15+0.07 (depth 10) hole, and at its upper end there is a pit with a height o...

Problems solved by technology

[0004] However, the bad consequences of the technical adjustment of the pit core-pulling direction are that the part structure is more complicated, the consistency of design, process and product assembly is not good, and the product differentiation expands, which is not conducive to large-scale mass production.
