Description

Technical field

[0001] The invention relates to the technical field of hot pressing die mechanisms, in particular to a hot pressing forming die structure. [Background Technology]

[0002] Hot pressing molds are generally flat, so when encountering products with corners or large arcs, it is easy to cause products to be crushed or cracked. Figures 1-2 The product 20 shown needs to be hot-pressed, but the product 20 is provided with a corner 30, which is easy to cause the product 20 to be crushed or cracked when it is formed using a general hot-pressing mold, resulting in a low yield rate of the product 20.

[0003] In view of this, it is necessary to provide a hot pressing mold structure to solve the above problems. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is that, when a sheet material to be hot-pressed is formed, the sheet material's non-conforming structure after hot-pressing forms a corner, and conventional hot-pressing dies are prone to causing damage or cracking of the sheet material, resulting in a low sheet forming yield. Therefore, the present invention provides a hot-pressing die structure to address this problem.

[0005] The present invention solves the technical problem by providing a hot pressing mold structure comprising:

[0006] The mother mold core is provided with a buckle groove at a position corresponding to the corner or curvature of the formed sheet. The buckle groove includes a placement groove and a limit groove. The limit groove is provided on the side wall of the placement groove. A buffer is provided in the buckle groove. The buffer includes an assembly part and a limit part. The assembly part is provided with a glue surface. The assembly part cooperates with the placement groove of the buckle groove to support the buffer part. The limit part is used to cooperate with the limit groove of the buckle groove to fix the buffer part. The buffer part plays a buffering role when the sheet is hot-pressed;

[0007] The male mold core is shaped like the side away from the corner or arc of the plate, and the male mold core cooperates with the female mold core to form the plate.

[0008] Preferably, the buffer is made of an elastic material, including but not limited to silicone.

[0009] Preferably, the assembly part and the limiting part in the buffer part are integrally injection molded using an injection mold.

[0010] Preferably, the buffer component is bonded and fixed inside the buckle slot.

[0011] Preferably, the method of forming a sheet material using a hot pressing mold structure is:

[0012] Step 1: Cut buckle grooves on the mother mold at the corners or arc positions of the plate;

[0013] Step 2: Using an injection mold to mold a buffer of a desired shape, the deformation of the buffer is selected according to the required range of the plate size after molding. The higher the required accuracy of the plate size after molding, the smaller the deformation of the buffer;

[0014] Step 3: Glue is applied to the buckle slot, and the buffer is fixed to the buckle slot by gluing. The double fixation of the limiting structure and the glue makes the buffer more firmly fixed in the buckle slot;

[0015] Step 4: Hot-press the sheet material by combining the female mold core and the male mold core with the buffer parts assembled.

[0016] The beneficial effect of the present invention is that, through a hot pressing mold structure, the present invention adopts a buckle groove provided at the corresponding position of the corner or curvature of the sheet material formed by the mother mold core, and the buffer part is fixedly connected in the buckle groove, so that the sheet material can play a buffering role at its corner or curvature during hot pressing, thereby improving the yield of sheet material forming, and this structure is simple, easy to process and easy to install.

[0024] To further illustrate the technical means and effects of the present invention, the following is a detailed description in conjunction with the embodiments of the present invention and the accompanying drawings.

[0025] The present invention provides a hot pressing mold structure, comprising:

[0026] The female mold core 100 is provided with a buckle groove 101 at a position corresponding to the corner or curvature of the formed plate. In this embodiment, the buckle groove 101 is trapezoidal in shape. The buckle groove 101 includes a placement groove 103 and a limiting groove 104. The limiting groove 104 is provided on the side wall of the placement groove 103. A buffer 102 is provided in the buckle groove 101. The buffer 102 includes an assembly part 105 and a limiting part 106. The assembly part 105 is provided with a glue surface. The assembly part 105 cooperates with the placement groove 103 of the buckle groove 101 to support the buffer 102. The limiting part 106 is used to cooperate with the limiting groove 104 of the buckle groove 101 to fix the buffer 102. The buffer 102 plays a buffering role when the plate is hot-pressed;

[0027] The male mold core 200 is contoured to the side away from the corner or arc of the plate, and the male mold core 200 cooperates with the female mold core 100 to form the plate.

[0028] The buffer 102 is made of elastic material, including but not limited to silicone.

[0029] The assembly part 105 and the limiting part 106 in the buffer part 102 are integrally injection molded using an injection mold.

[0030] In this embodiment, the buffer member 102 is fixed inside the buckle slot 101 by gluing.

[0031] Among them, the method of forming a plate using a hot pressing mold structure is:

[0032] Step 1: Cut the buckle groove 101 at the corner or arc position of the plate on the mother mold core 100;

[0033] Step 2: The buffer member 102 is injection molded into the desired shape by the injection mold. The deformation of the buffer member 102 is selected according to the required range of the plate size after molding. The higher the required accuracy of the plate size after molding, the smaller the deformation of the buffer member 102.

[0034] Step 3: Glue is applied to the buckle slot 101, and the buffer 102 is fixed to the buckle slot 101 by gluing. The double fixation of the limiting structure and the glue allows the buffer 102 to be more firmly fixed to the buckle slot 101.

[0035] Step 4: The female mold core 100 assembled with the buffer member 102 is combined with the male mold core 200 to form the plate through hot pressing.

[0036] The beneficial effect of the present invention is that the present invention adopts a hot pressing mold structure, which adopts a buckle groove 101 corresponding to the corner or curvature of the forming plate of the mother mold core 100, and the buffer part 102 is fixedly connected in the buckle groove 101. In this way, the plate can play a buffering role at its corner or curvature during hot pressing, thereby improving the yield of plate forming, and this structure is simple, easy to process and easy to install.

[0037] It should be pointed out that the present invention is not limited to the above-mentioned implementation mode, and any simple modification, equivalent change and modification made to the above-mentioned embodiment based on the technical solution of the present invention by any technician familiar with the profession shall fall within the protection scope of the present invention.
