Description

Multi-direction inward-drawing sliding block die

Technical Field

The utility model relates to an injection mold especially relates to a multidirectional interior slider mould of taking out.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic products, as shown in fig. 1 and 2, since there are four fasteners 101 inside some plastic products 10, it is necessary to design an injection mold that can be detached from the fasteners 101 at the same time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, the reliable and stable slider mould is taken out to multidirectional inwards.

In order to achieve the above object, the technical solution of the present invention is:

the utility model relates to a multi-direction inward-drawing slide block die, which comprises a fixed die plate, a movable die bottom plate, a guide block spring and a plurality of small slide blocks; the fixed die plate and the movable die plate are connected together in an abutting mode, the movable die plate and the movable die bottom plate are fixed together, the guide block is movably sleeved in the movable die plate and the movable die bottom plate, the inner ends of the small slide blocks are connected to the upper portion of the guide block in a sliding mode in a groove block matching mode, the outer ends of the small slide blocks extend into the die cavity, and a guide block spring is arranged between the bottom surface of the guide block and the movable die bottom plate.

The lower part of the guide block is movably sleeved in a stepped hole in the movable mould bottom plate, a hanging table at the lower end of the guide block can be abutted against the stepped surface of the stepped hole in the movable mould bottom plate, and a gap is formed between the hanging table at the lower end of the guide block and the stepped surface of the stepped hole in the movable mould bottom plate and is a stroke for moving the guide block.

The small sliding blocks are provided with four blocks which are in sliding connection with the upper parts of the guide blocks from four directions.

After the scheme is adopted, because the utility model discloses a fixed die plate, movable mould board, movable mould bottom plate, guide block spring, a plurality of little sliders, roof, thimble, the inner of a plurality of little sliders slips on the upper portion of guide block with channel block complex mode cunning, during the die sinking, the guide block jack-up under the effect of spring, little slider is drawn to the shrink of mold core centre of a circle by the spout of guide block, the slider breaks away from the inside wall buckle of product, has simple structure, the reliable and stable advantage of action.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 3, the utility model relates to a multidirectional interior slider mould of taking out, including fixed die plate 1, movable mould board 2, movable mould bottom plate 3, guide block 4, guide block spring 5, four little sliders 6, roof 7, thimble 8.

The fixed die plate 1 is connected with the movable die plate 2 in an abutting mode, the movable die plate 2 is fixed with the movable die bottom plate 3, the guide block 4 is movably sleeved in the movable die plate 2 and the movable die bottom plate 3, the four small sliding blocks 6 are connected with the upper portions of the guide blocks 4 in a sliding mode from four directions, the small sliding blocks 6 are matched with the guide blocks 4 in a groove block matching mode, namely, a sliding groove 61 on each small sliding block 6 is connected with a T-shaped sliding block 41 (shown in figure 6) on the upper portion of each guide block 4 in a sliding mode, the outer ends of the four small sliding blocks 6 extend into a cavity, and a guide block spring 5 is arranged between the bottom surface of each guide block 4 and the movable die bottom plate 3.

In this embodiment, the lower portion of the guide block 4 is movably sleeved in the stepped hole 31 of the movable mold base plate 3, the hanging platform 42 at the lower end of the guide block 4 can abut against the stepped surface of the stepped hole 31 of the movable mold base plate 3, and a gap is formed between the hanging platform 42 at the lower end of the guide block 4 and the stepped surface of the stepped hole 31 of the movable mold base plate 3, wherein the gap is a moving stroke of the guide block 4.

The utility model discloses a theory of operation:

1. mold closing state: as shown in fig. 3, the fixed mold 1 and the movable mold 2 are assembled, the guide block 4 is pressed into the fixed mold core 11 fixed to the fixed mold 1, and the small slide 6 is pulled by the slide groove guided by the guide block 4 to expand outside the fixed mold core 11.

2. Opening the mold: as shown in figure 4, the movable mold 2 is opened, the guide block 4 is jacked upwards under the action of the guide block spring 5, the small slide block 6 is drawn by the slide groove of the guide block 4 to the circle center of the fixed mold core 11 to be contracted, and the small slide block 6 is separated from the inner side wall of the product 10.

3. And (3) ejection state: as shown in fig. 5, the top plate 7 drives the ejector pin 8 to eject the product 10.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
