Description

Elastic insert structure of injection mold

Technical Field

The utility model relates to an injection mold technical field, concretely relates to injection mold's elasticity mold insert structure.

Background

The slider is a structure commonly used in injection molds for forming the reverse buckle, and after injection molding is completed and before a product is ejected, the slider needs to be taken off the reverse buckle to remove ejection interference of the product. When the existing sliding block is used for taking off the reverse buckle, the insert can be matched for use at most, the collision surface of the mold core of the existing insert is small, the insert is easy to damage, and when the insert is driven by the sliding block to be separated from the mold core, forward thrust is not generated, so that burrs are easy to appear during injection molding.

Disclosure of Invention

To the defect of above-mentioned prior art, the utility model provides an injection mold's elasticity mold insert structure, simple structure, convenient operation can effectually avoid bumping the face less hour, and the mold insert suffers the damage, and can prevent that the injection molding from producing the burr.

In order to achieve the above object, the utility model adopts the following technical scheme:

injection mold's elasticity mold insert structure, including back mould benevolence, shovel machine and slider, the slider passes through the mold insert subassembly and sets up in one side of back mould benevolence, and can drive the mold insert subassembly and remove towards back mould benevolence direction, be equipped with oblique guide pillar on the shovel machine, be equipped with the position of going with oblique guide pillar adaptation on the slider, cooperation through oblique guide pillar and position of going, make the slider can break away from back mould benevolence, the mold insert subassembly includes first mold insert, second mold insert and third mold insert, first mold insert is connected with the slider, second mold insert all is connected with first mold insert with the third mold insert, and the lateral wall of second mold insert towards first mold insert is equipped with the mounting groove, be equipped with the spring in the mounting groove, the one end of spring supports in the mounting groove, the other end of spring supports in the lateral wall of first mold insert, when oblique guide pillar inserts the position of going, the spring is in compression state.

In the above description, as a preferred option, a clamping groove is formed in the slider, a buckle adapted to the clamping groove is formed in the first insert, and the first insert is connected to the slider through the cooperation between the buckle and the clamping groove.

In the above description, the second insert is preferably connected to the first insert by a setscrew.

The utility model discloses produced beneficial effect is: the insert assembly comprises a first insert, a second insert and a third insert, and the range of the collision surface is enlarged by arranging the three inserts, so that the damage of the inserts is prevented; the second mold insert is equipped with the mounting groove towards the lateral wall of first mold insert, is equipped with the spring in the mounting groove, and the one end of spring supports in the mounting groove, and the other end of spring supports in the lateral wall of first mold insert, and when oblique guide pillar inserted the position of going, the spring was in compression state, and when the slider drove first mold insert and outwards removed, the spring of compression recovered to produce thrust, push second mold insert and third mold insert to back mould benevolence, produce the burr when preventing to mould plastics.

Drawings

FIG. 1: is a schematic cross-sectional structure diagram of an embodiment of the present invention;

the attached drawings indicate the following: 10-rear die core, 11-shovel machine, 12-slide block, 13-inclined guide post, 14-slide block, 15-first insert, 16-second insert, 17-third insert, 18-stop screw and 19-spring.

Detailed Description

To more clearly illustrate the structural features and technical means of the present invention and the specific objects and functions achieved thereby, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:

in this embodiment: as shown in fig. 1, an elastic insert structure of an injection mold comprises a back mold core 10, a shoveling machine 11 and a slide block 12, wherein the slide block 12 is arranged at one side of the back mold core 10 through an insert assembly and can drive the insert assembly to move towards the back mold core 10, the shoveling machine 11 is provided with an inclined guide post 13, the slide block 12 is provided with a slide position 14 matched with the inclined guide post 13, the slide block 12 can be separated from the back mold core 10 through the matching of the inclined guide post 13 and the slide position 14, the insert assembly comprises a first insert 15, a second insert 16 and a third insert 17, the slide block 12 is provided with a clamping groove, the first insert 15 is provided with a buckle matched with the clamping groove, the first insert 15 is connected with the slide block 12 through the matching of the buckle and the clamping groove, the second insert 16 and the third insert 17 are both connected with the first insert 15, the second insert 16 is connected with the first insert 15 through a filling screw 18, and the second insert 16 is provided with a mounting groove facing the side wall of the first insert 15, a spring 19 is arranged in the mounting groove, one end of the spring 19 abuts against the mounting groove, the other end of the spring 19 abuts against the side wall of the first insert 15, and when the inclined guide post 13 is inserted into the slide 14, the spring 19 is in a compressed state.

When the injection molding machine is used, the slide block 12 drives the first insert 15 to move outwards through the matching of the inclined guide post 13 and the slide 14, the compressed spring 19 recovers and generates thrust to push the second insert 16 and the third insert 17 to the rear mold core 10, so that burrs are prevented from being generated during injection molding, and then the product is completely separated from the injection molding machine.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, so any modifications, equivalent replacements, improvements, etc. made to the above embodiments by the technology of the present invention are all within the scope of the technical solution of the present invention.
