[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the surface processing of objects by changing the physical state of the molded material, and is known as the "mother of industry". Injection molds are tools for producing plastic products. Generally, injection molds are composed of an upper mold and a lower mold. During injection molding, the upper mold and the lower mold are closed to form a runner system and a mold cavity for plastic products. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the mold cavity and cooled and formed in the mold cavity. At the same time, the molten plastic is also cooled in the runner system to form a runner system condensate. After the plastic product is formed, the upper mold and the lower mold are separated, and the plastic product is ejected from the mold cavity through the ejection system and leaves the mold. Finally, the upper mold and the lower mold are closed again for the next injection molding. The entire injection molding process is carried out in a cycle.

[0003] At present, when the molding height of injection molded products is relatively high, it is necessary to accurately position the products during the molding process to ensure the molding quality.

[0023] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a mechanism for continuous positioning during the forming process of a stamping die is provided, comprising an upper die 10 and a lower die 20, wherein the upper die 10 comprises an upper die seat 100, an upper die forming block 101 is arranged below the upper die seat 100, the upper die 10 comprises a lower die seat 200, a lower die forming block 201 is arranged below the lower die seat 200, the upper die forming block 101 is buckled with the lower die forming block 201 to form a forming cavity, a groove 202 is provided on the lower die forming block 201, a slide groove 203 is provided in the groove 202, a slider 204 is clamped in the slide groove 203, and the slider 204 moves along the slide groove 203 moves, a slider fixing seat 205 is installed on the slider 204, one side of the slider fixing seat 205 is connected to a slider insert 206, and the slider insert 206 is connected to a positioning block 207 on the side away from the slider fixing seat 205, and the positioning block 207 is abutted against the molded product at one end away from the slider insert 206, and a driving block 102 is fixedly set at the lower right side of the upper mold forming block 101, and the driving block 102 is inserted into the slider insert 206 at one end away from the upper mold forming block 101, and a stop block 208 abutting against the slider insert 206 is also set on the lower mold forming block 201.

[0024] In this embodiment, a spring installation groove 209 is opened at the upper right corner of the lower mold forming block 201, and a helium spring 210 is installed in the spring installation groove 209. The axial end of the helium spring 210 is in contact with the slider fixing seat 205. The slider 204 moves to the right under the action of the driving block 102, so that the helium spring 210 is in a compressed state. When the upper mold 10 and the lower mold 20 are completed after the mold is closed, the helium spring 210 is released from compression to a natural state.

[0025] In this embodiment, the slider insert 206 is provided with a through slot 206a, the driving block 102 is provided with an inclined surface corresponding to the slider insert 206, and the driving block 102 is movably inserted into the through slot 206a of the slider insert 206 and fits with the inclined surface of the slider insert 206. Since the driving block 102 is movably inserted into the through slot 206a of the slider insert 206 and fits with the inclined surface of the slider insert 206, the upper mold 10 and the lower mold 20 can fit closely when the mold is closed, thereby ensuring the positioning of the product during the molding process, preventing the slider insert 206 from being deformed by the injection pressure during the injection molding process, and ensuring the production quality of the product.

[0026] In this embodiment, a pouring port 100 a is installed on the upper mold base 100 , and a pouring channel 101 a is formed in the lower mold forming block 201 , and the pouring channel 101 a is communicated with the forming cavity.

[0027] In this embodiment, the contact surface between the upper die base 100 and the upper die forming block 101 is locked and fixed by bolts, and the contact surface between the lower die base 200 and the lower die forming block 201 is locked and fixed by bolts.

[0028] The embodiment of the utility model provides a mechanism for continuous positioning during the stamping die forming process. In a natural state, the positioning block 207 can position the product. When the upper mold 10 and the lower mold 20 are molded together, during the downward movement of the upper mold 10, the driving block 102 first contacts the slider insert 206, and the slider 204 moves to the right under the action of the driving block 102, so that the nitrogen spring is compressed. At this time, the driving block 102 is stuck in the slider fixing seat 205 and the slider insert 206, and the upper mold forming block 101 is about to contact the product. The upper mold 10 continues to move downward, and the upper mold forming block 101 begins to contact the product and start the molding work. The product begins to shrink inward, and the upper mold 10 continues to move downward, thereby completing the molding action. In this process, the driving block 102 continues to move downward, and the inclined surface of the driving block 102 begins to contact the slider insert 206. At this time, the slider 204 begins to reset under the action of the nitrogen spring, so at this time, the positioning block 207 shrinks inward with the product and continues to accurately position the product, thereby completing the molding work. After the molding work is completed, the upper mold 10 starts to move upward, the driving block 102 starts to contact the inclined surface of the slider insert 206, driving the slider insert 206 and the slider 204 to move to the right, resetting the positioning block 207, and compressing the nitrogen spring. The upper mold 10 continues to move upward, the driving block 102 straightens and contacts the slider insert 206, and the slider 204 stops moving. Then the upper mold 10 moves upward to reach the highest point of the punch press, and a working process is completed.

[0029] The mechanism for continuous positioning during the molding process of the stamping die provided by the embodiment of the utility model adopts a simple slider 204 to ensure continuous positioning of the product during the molding process, ensure the molding quality, thereby saving mold costs, and can prevent the injection pressure during the injection molding process from deforming the slider insert 206, thereby ensuring the production quality of the product.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
