Description

Technical Field

[0001] The utility model relates to an injection mold, in particular to a split type combined slide block mold. Background Art

[0002] Plastic injection molds are tools for producing plastic products and are widely used. In plastic injection molds, many products have multi-directional demoulding structures on the side walls. Figure 5 As shown, the side wall 101 of the product 100 is inconsistent with the opening direction of the mold, and the product is difficult to demold. Traditional slider mechanisms generally have problems such as difficult processing, complex structure, and high cost. Utility Model Content

[0003] The utility model aims to provide a split combined slider mold which meets the requirements of undercut demoulding in different directions.

[0004] To achieve the above purpose, the technical solution of the utility model is:

[0005] The utility model is a split type combined slider mold, including a fixed template, a movable template, an inclined guide column, a main slider, a limit block, a small slider seat, a small slider, a small slider insert and a stop block;

[0006] The fixed template is connected to the movable template, the upper end of the inclined guide column is fixed on the fixed template, the lower part of the inclined guide column is movably inserted in the guide column hole of the main slider, the main slider is slidably connected to the movable template, the inclined top surface of the small slider is connected to the inclined bottom surface inside the main slider, the outer end of the small slider is against the limit block, the upper end of the limit block is fixed on the main slider, the lower part of the small slider is slidably connected to the guide groove of the small slider seat, the lower end of the small slider seat is fixed on the movable template, the outer end of the small slider insert is fixed to the inner end of the small slider, the inner end of the small slider insert extends into the cavity, the upper part of the stop block is gapped through the give way hole of the main slider, the lower part of the stop block is gapped through the vertical groove of the small slider, and the lower end surface of the stop block is slidably connected to the guide groove of the small slider seat.

[0007] The utility model also includes a panel, a hot runner plate, a square iron, a bottom plate and a top plate; the panel, the hot runner plate and the fixed mold plate are fixed together in sequence, the movable mold plate is connected to the bottom plate through the square iron, and the top plate is arranged between the movable mold plate and the bottom plate.

[0008] After adopting the above scheme, since the utility model includes a fixed template, a movable template, an inclined guide column, a main slider, a limit block, a small slider seat, a small slider, a small slider insert and a stop block, when the mold is opened, the fixed template and the movable template are separated, the main slider is separated from the shovel base on the fixed template, the inclined guide column drives the main slider to move outward, and the small slider seat drives the small slider to move downward and outward, so that the small slider is separated from the inclined surface of the product, and at the same time, the small slider insert fixed on the small slider is separated from the undercut hole of the product. The utility model adds small sliders with different undercut directions in the large slider, and the main slider and the small slider are synchronously moved. The main slider and the small slider are demolded from their respective demolding directions, which meets the demolding requirements of undercuts in different directions of the product, and are separated from the set sliding clamp stroke position. When the mold is closed, they move to the designated position from their respective directions to cooperate with each other to avoid mutual interference, which greatly simplifies the mold structure, improves the overall quality and service life of the mold, reduces costs, reduces maintenance, and improves production efficiency.

[0009] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1-Figure 5 As shown, the utility model is a split combined slider mold, including a panel 1, a hot runner plate 2, a fixed mold plate 3, a movable mold plate 4, a square iron 5, a bottom plate 6, a top plate 7, an inclined guide column 8, a main slider 9, a limit block 10, a small slider seat 20, a small slider 30, a small slider insert 40 and a stop block 50.

[0016] The panel 1, the hot runner plate 2, and the fixed mold plate 3 are fixed together in sequence, the fixed mold plate 3 and the movable mold plate 4 are abutted together, the movable mold plate 4 is connected to the bottom plate 6 through the square iron 5, and the top plate 7 is arranged between the movable mold plate 4 and the bottom plate 6. The upper end of the inclined guide column 8 is fixed on the fixed template 3, and the lower part of the inclined guide column 8 is movably inserted into the guide column hole 91 of the main slider 9. The main slider 9 is slidably connected to the movable template 4. The inclined top surface of the small slider 30 is abutted against the inclined bottom surface inside the main slider 9. The outer end of the small slider 30 abuts against the limit block 10. The upper end of the limit block 10 is fixed on the main slider. The lower part of the small slider 30 is slidably connected to the guide groove 201 of the small slider seat 20. The lower end of the small slider seat 29 is fixed on the movable template 4. The outer end of the small slider insert 40 is fixed to the inner end of the small slider 30. The inner end of the small slider insert 40 extends into the cavity. The upper part of the stop block 50 is gap-through in the make-away hole 92 of the main slider 9, and the lower part of the stop block 50 is gap-through in the vertical groove 301 of the small slider 30. The lower end surface of the stop block 50 is slidably connected to the guide groove 201 of the small slider seat 20.

[0017] The working principle of this utility model:

[0018] When the mold is opened, the fixed template 3 and the movable template 4 are separated, the main slider 9 is separated from the shovel base on the fixed template 3, the inclined guide column 8 drives the main slider 9 to move outward, and the small slider seat 20 drives the small slider 30 to move downward and outward, so that the small slider 30 is separated from the inclined surface 101 of the product 100, and at the same time, the small slider insert 40 fixed on the small slider 30 is separated from the undercut hole 102 of the product 100, and the main slider 9 and the small slider 30 are demolded from their respective demolding directions through the synchronous action of the main slider 9 and the small slider 30.

[0019] When the mold is opened, the fixed template 3 is separated from the movable template 4. At this time, the main slider is separated from the shovel base on the fixed template due to the opening of the movable template. The inclined guide column drives the main slider to move outward so that the main slider is separated from the small slider. At the same time, the small slider seat drives the small slider to move downward and outward, so that the small slider is separated from the inclined surface of the product, and the small slider insert fixed on the small slider is separated from the undercut hole of the product. The utility model uses the main slider to synchronously separate from each demoulding direction to the set sliding clamp stroke position, and when closing the mold, it moves from each direction to the specified position to cooperate with each other without interference.

[0020] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope covered by the patent of the present invention.
