Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a sliding block structure for stamping molds. Background Technology

[0002] In the design of metal stamping dies, situations often arise where a two-way motion slider mechanism with side slide forming, stripping, and floating is required. Traditional slider structures suffer from insufficient guiding accuracy, leading to slider jamming or misalignment, frequently resulting in inaccurate resetting, damage to products and parts, and difficulties in mass production. Therefore, there is an urgent need in this field for a novel slider structure that solves these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a sliding block structure for a stamping die to solve the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stamping die slider structure includes a lower template with a mounting hole, a slider rail within the mounting hole, a vertical rail on the slider rail, and a forming insert. A spring cover plate is provided on one side of the forming insert, and a spring is provided between the forming insert and the spring cover plate. Dovetail grooves that cooperate with each other are provided on the slider rail and the forming insert. An upper die pin that cooperates with each other is also provided on the upper side of the forming insert.

[0005] As a preferred technical solution, there are two vertical slide rails, located on the left and right sides of the slider slide rail respectively.

[0006] This utility model features a dovetail groove, especially a set of dovetails designed at the bottom and sides of the molding block. Figure 5 (8), and the slide rail dovetail ( Figure 6 (8) With the front and rear sliding mechanism in place, after the forming block is inserted into the slide rail, the entire assembly is then installed in the lower template slide rail groove. Figure 8 The slider slides up and down, and forward and backward as well as up and down within a precisely fitted dovetail groove or slide rail groove. This significantly improves the fit and stability. The dovetail and slide rail are preferably machined using wire cutting, a technique known in the art, to ensure a high-precision sliding fit. The preferred machining clearance for the dovetail and slide rail is a sliding clearance of +0.002mm on one side, which allows the slider to slide within the track in both directions, reducing jamming or misalignment and minimizing damage to the product and slider mechanism parts. This solves the problem of low guiding accuracy in existing floating sliders.

[0007] Compared with the prior art, the advantages of this utility model are as follows: the slider structure of this utility model can realize that the bidirectional (up and down and forward and backward) movement of the floating slider can be precisely reciprocated within the slide rail. The slider slides without obstruction, can be accurately reset, there is no risk of parts being damaged, no product damage, no defective products are generated, the stamping speed can be increased by more than 40%, the production efficiency can be increased by more than 30%, the mold maintenance cost can be reduced, and the cost of spare parts can be reduced by more than 50%.

[0009] The present invention will be further described below with reference to the embodiments.

[0010] Example 1:

[0011] See Figure 1A stamping die slider structure includes a lower template 1 with a mounting hole 11. A slider rail 2 is provided in the mounting hole 11, and a vertical rail 21 is provided on the slider rail 2. The structure also includes a forming insert block 3 with a spring cover plate 5 on one side. A spring 6 is provided between the forming insert block 3 and the spring cover plate 5. The slider rail 2 and the forming insert block 3 are provided with dovetail grooves 7 that cooperate with each other. The upper side of the forming insert block 3 is also provided with an upper die pin 4 that cooperates with each other.

[0012] In this embodiment, there are two vertical slide rails 21, located on the left and right sides of the slider slide rail 2 respectively; During assembly, such as Figure 2 , Figure 3 and Figure 4 As shown, a spring 6 is installed between the molding block 3 and the spring cover plate 5. The molding block 3, spring cover plate 5, and spring 6 are then installed into the slider rail 2. Finally, the assembled slider rail 2, molding block 3, spring cover plate 5, and spring 6 are installed into the mounting hole 11 of the lower template 1. Figure 4 As shown, when the mold is closed, the upper mold pin 4 pushes the forming block 3, which works in conjunction with the spring 6 to make the forming block 3 slide back and forth in the slider rail 2.

[0013] Due to product structure limitations, such as Figure 10 The shell-shaped product shown requires the molding block 3 to move in both vertical and horizontal directions. Traditional structures only install a floating top pin under the molding block 3, and it only slides back and forth within the template mounting hole, resulting in poor guidance. This invention, after improvement, adds a double-layer dovetail groove 7 to the slider rail 2 and the molding block 3 (e.g., Figure 5 , Figure 6 As shown), the dovetail groove 7 on the molding block 3 and the dovetail groove 7 on the slider rail 2 are precisely slidably engaged, and pushed by the upper mold pin 4 (as shown). Figure 3 As shown), this allows for precise sliding of the molding block 3 back and forth; two vertical slide rails 21 are added to each side of the slider slide rail 2, as shown. Figure 9 As shown, the material is ejected by the lower mold floating, and slides through the mounting hole 11 of the lower mold plate 1 in the slide rail groove 12 (as shown). Figure 9 Precision sliding fit (such as) Figure 7 , Figure 8 As shown in the figure, it can achieve precise up and down sliding, so that the up and down and forward and backward movements can all be precisely reciprocated within the slider rail 2.

[0014] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
