Description

Technical field

[0001] The invention relates to a slider positioning structure of a mold. [Background Technology]

[0002] Plastic products are increasingly appearing in our daily lives. With the rapid development of the plastics industry and the continuous improvement in strength and quality of general-purpose and engineering plastics, these products are often manufactured using injection molds. The mold release mechanism typically utilizes a slider, which is driven by a drive mechanism and then moves the core to release the mold. After injection molding, the slider must be retracted to its travel position and positioned for mold opening. However, existing slider positioning mechanisms are complex and costly.

[0003] The present invention aims to solve the technical problems of the existing slider positioning structure being complex and costly. [Summary of the invention]

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a slider positioning structure for a mold which has a simple structure, low cost, is applicable to various molds, and is easy to manufacture and equip.

[0005] The object of the present invention is achieved like this:

[0006] A slider positioning structure for a mold, wherein the slider of the mold can slide on a wear-resistant plate, and the wear-resistant plate is provided with a wear-resistant plate fixing hole fixed to the mold. It is characterized in that a positioning hole is provided at the bottom of the slider, and the positioning hole is a V-shaped groove; an elastic locator passes through the wear-resistant plate and can be stuck in the positioning hole, and the elastic locator includes an elastic part, and a positioning column is provided on the top of the elastic part, and the top of the positioning column is ∧-shaped, and a limiting step is also provided on the positioning column.

[0007] The slider positioning structure of the mold as described above is characterized in that the top end of the positioning column is arc-shaped.

[0008] The slider positioning structure of a mold as described above is characterized in that the wear-resistant plate is provided with a wear-resistant plate hole for the elastic locator to pass through.

[0009] The slider positioning structure of the mold as described above is characterized in that there is a pair of elastic positioners, which are arranged side by side; there is also a pair of positioning holes, which are arranged side by side and correspond to the pair of elastic positioners.

[0010] The slider positioning structure of the mold as described above is characterized in that the upper surface of the wear-resistant plate is provided with a wear-resistant layer, and the lower surface of the slider is also provided with a wear-resistant layer.

[0011] The beneficial effects of the present invention are:

[0012] The present invention features an elastic locator that passes through the wear-resistant plate. The locator comprises an elastic member with a positioning post at the top and a V-shaped positioning hole machined into the bottom of the slider. After injection molding is completed and the slider retracts to its travel position during mold opening, the elastic locator springs up under the action of the elastic member to engage the slider, stopping its movement and thus achieving positioning. This simple structure, low cost, is applicable to various molds, and is easy to manufacture and assemble.

[0018] The present invention will be further described below in conjunction with the accompanying drawings:

[0019] A slider positioning structure for a mold, wherein the slider 1 of the mold can slide on a wear-resistant plate 2, and the wear-resistant plate 2 is provided with a wear-resistant plate fixing hole 3 fixed to the mold, and a positioning hole 4 is provided at the bottom of the slider 1, and the positioning hole 4 is a V-shaped groove; an elastic locator 5 passes through the wear-resistant plate 2 and can be stuck into the positioning hole 4, and the elastic locator 5 includes an elastic member 6, and a positioning column 7 is provided on the top of the elastic member 6, and the top of the positioning column 7 is in a ∧ shape, and a limiting step 8 is also provided on the positioning column 7. The present invention is provided with an elastic locator 5 passing through the wear-resistant plate, and the elastic locator 5 includes an elastic member 6, and a positioning column 7 is provided on the top of the elastic member 6, and a positioning hole 4 with a V-shaped groove is processed at the bottom of the slider. After the injection molding is completed, when the mold is opened, the slider 1 retreats to the stroke position, and the elastic locator 5 pops up and clamps the slider 1 under the action of the elastic member 6, and the slider 1 stops moving, thereby realizing the positioning of the slider.

[0020] The top of the positioning post 7 of the present invention is an arc 71, which makes the positioning post 7 more smooth when it is inserted into the positioning hole 4 without getting stuck. The positioning hole 4 is also preferably provided with a smooth transition slope to facilitate the positioning post 7 to exit the positioning hole 4.

[0021] The wear-resistant plate 2 of the present invention is provided with a wear-resistant plate hole 9 for the elastic locator 5 to pass through. The upper portion of the positioning post 7 is rectangular, and the wear-resistant plate hole 9 is also rectangular. The lower portion of the positioning post 7 is cylindrical, and the elastic member 6 is a cylindrical spring. A stop step 8 is provided between the upper and lower portions of the positioning post 7. The stop step 8 functions to prevent the positioning post 7 from fully penetrating the wear-resistant plate 2 and to limit the upward travel of the positioning post 7.

[0022] The elastic positioners 5 of the present invention are a pair, and the pair of elastic positioners are arranged side by side; the positioning holes 4 are also a pair, and the pair of positioning holes are arranged side by side and correspond to the pair of elastic positioners.

[0023] The wear-resistant plate of the present invention has a wear-resistant layer on its upper surface and a wear-resistant layer on its lower surface. The thickness of these two wear-resistant layers ranges from 3 mm to 30 mm. The wear-resistant layers can be made of tool steel, cemented carbide, ceramic, steel, or graphite. Cemented carbide is most preferred. Cemented carbide is manufactured through powder metallurgy using refractory metal carbides such as tungsten carbide and titanium carbide and a metal binder such as cobalt or nickel. It exhibits extremely high hardness and wear resistance, can withstand high temperatures and high pressures, and is well-suited for use in manufacturing wear-resistant plates for injection molds.

[0024] The slider 1 of the present invention comprises a body 11, a connecting post 12 is provided on the rear side of the body 11, and a positioning protrusion 13 is provided on the rear side wall of the connecting post 12. The connecting post 12 and the positioning protrusion 13 are used to facilitate connection with the driving device.
