CN202781693U - Injection mold with jacking slide block - Google Patents

Abstract

The utility model discloses an injection mold with a jacking slide block, comprising a fixed mold plate and a moving mold plate, wherein an oblique guide pole is arranged on the fixed mold plate; a moving mold core is arranged on the moving mold plate; a slide block is inserted and arranged in the side face of the moving mold plate; the oblique guide pole is inserted and arranged in the middle of the slide block; a limit block is fixedly arranged on the moving mold plate; the side of the limited block is provided with a bulge block obliquely arranged; a through sliding chute is obliquely formed in the side face of the slide block; and the bulge block on the limited block is inserted into the through sliding chute. By utilizing the design of using an oblique guide pole core-pulling mechanism, the triggering of the oblique guide pole to the slide block is used as a power source of core pulling through mold splitting and simultaneously the limited block is arranged according to irregular back-off position so that the slide block slides obliquely along a certain direction and finally a plastic part can be demolded successfully. According to the scheme, the injection mold is simple in structure, reliable in structural motion, and convenient and quick to manufacture and process.

Description

A kind of injection mold with jacking slider

technical field

The utility model relates to the technical field of injection molds, in particular to an injection mold with a jacking slider. the

Background technique

In the known technical field, injection molds are one of the important means to obtain plastic products in industrial production. Usually, when faced with some special-shaped undercuts, the core-pulling direction of the core-pulling mechanism of the mold cannot be the same as that of ordinary core-pulling mechanisms. , moving along the parting surface, if the core-pulling mechanism is not well designed at this time, it will cause scratches and scratches on the plastic parts, which will affect the product quality of the plastic parts. the

Utility model content

The technical problem to be solved by the utility model is to provide an injection mold that can adapt to the core-pulling position of the special-shaped undercut. the

The technical scheme adopted by the utility model to solve the technical problem is: an injection mold with a jacking slider, including a fixed template and a movable template, an inclined guide column is installed on the fixed template, and A movable mold core is installed on the template, a slider is embedded and installed on the side of the movable mold core, and the inclined guide post is inserted and installed in the middle of the slider, and a limit block is fixedly installed on the movable template , and the side of the limiting block has a protruding block arranged obliquely, the side of the sliding block is obliquely provided with a through chute, and the protruding block on the limiting block is inserted into the through chute. the

The beneficial effects of the utility model are: the utility model adopts the design of the inclined guide column core-pulling mechanism for reference, through the mold parting, the action of the inclined guide column to the slider is used as the power source of the core-pulling, and at the same time, according to the position of the special-shaped undercut The limit block is set, so that the slider slides obliquely in a certain direction, and finally the plastic part can be demolded smoothly. This scheme has a simple structure, reliable structural movement, and convenient and fast manufacturing and processing. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Fig. 1 is the structural representation of the utility model. the

FIG. 2 is a schematic diagram of a partially enlarged structure of FIG. 1 . the

Fig. 3 is a schematic cross-sectional structure diagram of the utility model. the

FIG. 4 is a partial cross-sectional structural schematic diagram of FIG. 3 . the

In the figure: 1. Moving mold core, 2. Slide block, 2-1. Through chute, 3. Inclined guide post, 4. Limiting block. the

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model. the

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of injection mold of the utility model with jacking slide block comprises a fixed template and a movable template, and an inclined guide column 3 is installed on the fixed template, A movable mold core 1 is installed on the movable template, and a slide block 2 is embedded in the side of the movable mold core 1, and the inclined guide post 3 is inserted and installed in the middle of the slide block 2, and on the side of the movable mold core 1 The limit block 4 is fixedly installed on the moving template, and the side of the limit block 4 has a raised block arranged obliquely, and the side of the slide block 2 is obliquely provided with a through chute 2-1, so The protruding block on the above-mentioned limiting block 4 is inserted into the through slide groove 2-1. the

When the mold is parted, the movable template is separated from the fixed template. At this time, the inclined guide column 3 fixed on the fixed template moves the slider 2 backward, but due to the existence of the limit block 4, the slider can only move along the through chute. 2-1 rises, and finally makes the slider 2 break out of the special-shaped undercut position, so that the plastic part can be demolded smoothly. the

Taking the above-mentioned ideal embodiment according to the present utility model as inspiration, through the above-mentioned explanation content, relevant staff can carry out various changes and modifications within the scope of not departing from the technical thought of this utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims. the
