Description

Movable needle inserting mechanism of injection mold

Technical Field

The utility model belongs to the technical field of injection molds, and particularly relates to a movable needle inserting mechanism of an injection mold.

Background

The insert pin is a product formed by fine grinding, has a series of excellent performances such as high hardness, wear resistance, better strength and toughness, heat resistance, corrosion resistance and the like, and particularly has high hardness and wear resistance, and is generally arranged on a die for blanking, so that materials are separated or plastically deformed, and the required part is obtained.

Currently, the publication number is: CN211492717U, discloses an insert needle for injection mold. The utility model provides a mold insert for injection mold, includes mold insert body and cooling tube, the inside first cavity that extends along mold insert body axial that is provided with of mold insert body, in the top of cooling tube stretched into first cavity, clearance setting between cooling tube and the first cavity, the top face of cooling tube with the interior top surface contact of first cavity, the top of cooling tube is provided with the cell body of intercommunication cooling tube inside and first cavity, cooling tube and inlet channel intercommunication, first cavity and outlet channel intercommunication. Solves the problems that the structure of the insert pin in the prior art is not well combined with a cooling water channel and the cooling range is small.

The existing injection mold needs to put copper parts into the mold before closing the mold, and then injection molding is carried out, because the cavity opening of the placement area on the mold is smaller, hands are not easy to stretch into the mold, so that the copper parts are difficult to place, the situation that the placement is not in place is easy to occur, the copper parts fall into the mold groove, and then pick up and put again, and the production efficiency is low.

Disclosure of Invention

The utility model aims to provide a movable insert pin mechanism of an injection mold, which has the advantages that copper parts are conveniently placed on an insert pin, and the insert pin and the copper parts are pressed back to the original positions together through die assembly.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a movable needle mechanism of inserting of injection mold, includes the template, the mould benevolence is installed at the top of template, the inside of template and mould benevolence is all sliding connection has movable needle of inserting, movable needle's internally mounted has the spring with template fixed connection, copper part is installed at movable needle's top.

By adopting the technical scheme, the movable insert pin is pushed out by the elastic force of the spring and is higher than the top of the die core, then the copper part is placed on the movable insert pin, the movable insert pin and the copper part are pressed back to the original position through the die assembly, and then injection molding is carried out, so that the copper part is placed on the insert pin conveniently, the insert pin and the copper part are pressed back to the original position through the die assembly conveniently, the copper part is placed conveniently, the situations that the copper part is not placed in place and the copper part falls into the die groove are reduced, and the use is convenient.

The utility model is further provided with: the top of the template is provided with a fixed guide needle which is in sliding connection with the movable insert needle, the spring is sleeved on the surface of the bottom end of the fixed guide needle, and the movable insert needle is sleeved on the surfaces of the fixed guide needle and the spring.

By adopting the technical scheme, the ejection stroke of the movable insert pin can be positioned by installing the fixed guide pin, so that the stability of the movable insert pin when the movable insert pin is slid is improved.

In summary, the utility model has the following beneficial effects:

the movable insert pin is pushed out by the elastic force of the spring and is higher than the top of the die core, then the copper part is placed on the movable insert pin, and the movable insert pin and the copper part are pressed back to the original position through the die assembly, so that the copper part is placed on the insert pin conveniently, the insert pin and the copper part are pressed back to the original position through the die assembly conveniently, the copper part is placed conveniently, the situations that the copper part is placed in place and the copper part falls into the die groove are reduced, and the use is convenient.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Example 1:

referring to fig. 1 and 2, a movable insert pin mechanism of an injection mold comprises a template 1, wherein a mold core 2 is arranged at the top of the template 1, movable insert pins 3 are slidably connected inside the template 1 and the mold core 2, a spring 5 fixedly connected with the template 1 is arranged inside the movable insert pins 3, and copper parts 6 are arranged at the top of the movable insert pins 3; the movable insert 3 is ejected by the elastic force of the spring 5 and is higher than the top of the die core 2, then the copper part 6 is placed on the movable insert 3, and the movable insert 3 and the copper part 6 are pressed back to the original position through the die assembly, so that the copper part is placed on the insert conveniently, the insert and the copper part are pressed back to the original position through the die assembly conveniently, the copper part is placed conveniently, the situation that the copper part is not placed in place and the copper part falls into a die groove is reduced, and the die is convenient to use.
