Description

Technical Field

[0001] The utility model relates to the field of plastic mold sliders, in particular to a tunnel slider. Background Art

[0002] In injection molding production, the demoulding mechanism is an important component of the plastic mold. Whether it can successfully eject the plastic part from the mold is directly related to the production efficiency of the mold and the yield rate of the plastic part.

[0020] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0021] Example 1

[0022] According to a tunnel slider provided by the utility model, Figure 1 As shown, it includes a tunnel small slider seat 1, a tunnel small slider oblique guide block 2, a tunnel small slider insert fixing block 3 and a tunnel small slider insert 5. The tunnel small slider insert 5 is connected to the tunnel small slider seat 1 through the tunnel small slider insert fixing block 3, and the tunnel small slider seat 1 is provided with a tunnel small slider oblique guide block 2.

[0023] The tunnel small slider oblique guide block 2 includes a first oblique block and a second oblique block, the first oblique block is connected to the second oblique block, the connection angle between the first oblique block and the second oblique block is an obtuse angle, and the second oblique block is provided with a center hole. The first oblique block is adapted to be connected in the groove on the tunnel small slider seat 1, and the second oblique block extends out of the tunnel small slider seat 1. The tunnel small slider insert fixing block 3 is provided with a connecting groove and a plurality of fixing holes, and the connecting groove is adapted to be connected with the connecting block on the other end of the tunnel small slider insert 5. The tunnel small slider insert 5 includes a first tunnel small slider insert and a second tunnel small slider insert, the first tunnel small slider insert is connected to the second tunnel small slider insert, and the length of the second tunnel small slider insert is greater than that of the first tunnel small slider insert. A first inclined surface is provided at one end of the first tunnel small slider insert, and the first inclined surface is adapted to be connected with the second inclined surface on the second tunnel small slider insert.

[0024] Example 2

[0025] The utility model also provides a trolley case handle, such as Figure 2 As shown, a tunnel slider is used.

[0026] More specifically, the tunnel slider is connected to the large slider seat 6, the tunnel small slider oblique guide block 2 extends out of the large slider seat 6, a large slider insert 7 is provided on the side of the large slider seat 6, and the tunnel small slider insert 5 extends out of the large slider insert 7, the large slider insert 7 abuts the product, and the large slider seat 6 is connected to the oil cylinder through the oil cylinder link T-head. When opening the mold, the tunnel small slider oblique guide block 2 fixed to the front mold drives the tunnel small slider seat 1, so that it can be pulled loose on the inclined surface of the tunnel small slider seat 1, so that the tunnel small slider insert 5 loosens the product. In the process of pulling the core of the tunnel small slider seat 1, the large slider insert 7 does not move and pushes the side of the product to prevent the tunnel small slider insert 5 from having too much tightening force in the product and deforming the product. After opening the mold, the oil cylinder pulls the large slider seat 6 again, so the core is pulled twice to ensure the reliability of the product core pulling structure and eliminate the risk of the product being damaged by the slider.
