[0035] A mold is a tool or device used to manufacture an article, typically used to shape raw materials such as metal, plastic, rubber, etc. by pressing, casting, injection, etc. into specific shapes and sizes of parts or products. The main function of the mold is to replicate the shape and structure of the parts or products. Through the design and manufacture of the mold, the same parts can be mass-produced to ensure the accuracy, quality and appearance of the products. Molds are widely used in industrial production and are an indispensable part of the mass production process. Molds play a crucial role in modern industry, providing efficient and precise tools for mass production. After the molding process is completed, demolding is required. Mold demolding refers to the process of smoothly removing the molded product or part from the mold after the molding process is completed. The demolding process is crucial to ensure the long-term service life of the mold, the surface quality of the product and the production efficiency. Demolding operation requires special attention to avoid damaging the molded product or affecting its quality.

[0036] However, most current molds can only mold one product at a time, and even if they can mold multiple products, they are not convenient to demold and have low production efficiency.

[0037] Based on this, please refer to Figure 1 、 Figure 2 and Figure 3 The mold 1000 provided in the embodiments of the present application can effectively improve the above-mentioned technical problems. The mold 1000 can mold multiple products at a time, and is also convenient to demold, improving the production efficiency.

[0038] Figure 1 A first perspective view of the mold 1000 provided in the embodiments of the present application; Figure 2 A second perspective view of the mold 1000 provided in the embodiments of the present application; Figure 3 A schematic view of the A-A section provided in the embodiments of the present application.

[0039] As Figure 1 、 Figure 2 and Figure 3As shown, the mold 1000 in the embodiment includes a first mold plate 100, a second mold plate 200, a plurality of inner wall forming modules 300, and a plurality of outer wall forming modules 400. The first mold plate 100 is provided with a melt pool 110. The first mold plate 100 is provided with a main runner 120 and a plurality of branch runners 130. The melt pool 110 is in communication with the plurality of branch runners 130 through the main runner 120. The second mold plate 200 is connected with the first mold plate 100 and is stacked. The second mold plate 200 is provided with a plurality of mold cavities 210. Each mold cavity 210 is in communication with at least one branch runner 130. Each mold cavity 210 is provided with an inner wall forming module 300. Each mold cavity 210 is provided with an outer wall forming module 400. In each mold cavity 210, the outer wall forming module 400 is arranged in a spaced manner around the inner wall forming module 300. The inner wall forming module 300 and the outer wall forming module 400 jointly form a product forming cavity 500. For each inner wall forming module 300, the inner wall forming module 300 includes a first module 310 and a second module 320. The first module 310 and the second module 320 are arranged in contact and are separable. That is, when the mold 1000 is used to form a product, the first module 310 and the second module 320 are combined to form the inner wall forming module 300, which jointly forms the product forming cavity 500 with the outer wall forming module 400 to produce the product. After the product is formed, the first mold plate 100 is disconnected from the second mold plate 200, and then the first module 310 and the second module 320 are taken out, which facilitates rapid demolding. The first module 310 and the second module 320 in the embodiment can be disassembled along the Z direction to achieve rapid demolding.

[0040] By arranging a plurality of mold cavities 210 and a plurality of branch runners 130, and arranging a forming module in each mold cavity 210, the mold 1000 can simultaneously produce a plurality of products, thereby improving production efficiency. The main runner 120 and the branch runner 130 are arranged on the first mold plate 100, which also facilitates demolding. By arranging the inner wall forming module 300 as two separable modules, the first module 310 and the second module 320 are disassembled after the product is formed to achieve rapid demolding and improve production efficiency.

[0041] The above-mentioned "connection between the first mold plate 100 and the second mold plate 200" is specifically described with reference to Figure 1 and Figure 2The first template 100 and the second template 200 in the embodiment are connected by threads. The first template 100 can be conveniently disassembled by threads, so as to facilitate subsequent demolding. The first template 100 in the embodiment is provided with first screw holes 140, and the second template 200 is provided with second screw holes. The first screw holes 140 and the second screw holes are correspondingly arranged, and the first screw holes 140 and the second screw holes are used for mounting threaded fasteners to connect the first template 100 and the second template 200. The threaded fasteners herein can be bolts, screws and the like, which are not limited herein. In order to ensure the stability of the connection between the first template 100 and the second template 200, the number of the first screw holes 140 and the second screw holes in the embodiment is multiple. The multiple first screw holes 140 and the multiple second screw holes are correspondingly arranged, and the multiple first screw holes 140 are arranged at intervals. Specifically, the number of the first screw holes 140 and the second screw holes in the embodiment is two. Two first screw holes 140 are respectively located on the two sides of the first template 100. Correspondingly, two second screw holes are respectively located on the two sides of the second template 200. The number of the first screw holes 140 and the second screw holes can also be three, four, five or the like, which is not limited herein. Of course, the first template 100 and the second template 200 can also be connected by welding, clamping or other connection methods, which are determined according to the actual processing conditions and are not limited herein.

[0042] In order to facilitate the removal of the first module 310 and the second module 320 during demolding, please refer to Figure 3 The first module 310 in the embodiment has a first inclined surface, and the second module 320 has a second inclined surface. The first inclined surface and the second inclined surface are arranged in contact. The contact surfaces of the first module 310 and the second module 320 are arranged to be inclined. When the first module 310 or the second module 320 is taken out, it can be taken out along the inclined surface. The design of the inclined surface helps to reduce the demolding force and ensure that the molded part can be smoothly taken out from the mold 1000. By proper inclination, the contact area between the module and the molded part during removal can be reduced, the demolding resistance can be reduced, and the demolding force can be reduced. Damage to the molded part caused by excessive demolding force can be avoided. In addition, the inclined surface can help to uniformly distribute the pressure and temperature in the mold 1000, thereby reducing the product deformation or stress concentration phenomenon caused by uneven pressure during the molding process. The included angle between the first inclined surface and the second inclined surface and the axis in the mold 1000 is an acute angle.

[0043] In order to facilitate demolding, the inner wall of the mold cavity 210 in the embodiment is provided with a draft angle. The draft angle in the embodiment is 3°. Of course, the draft angle can also be set to 0.5°, 1°, 1.5°, 2°, 2.5° or the like. The draft angle is determined according to the material of the mold 1000, which is not limited herein.

[0044] In order to facilitate quick demolding, the outer wall forming module 400 in the embodiment includes a third module 410 and a fourth module 420, which together enclose a hollow cylindrical shape, and the third module 410 and the fourth module 420 are arranged at intervals around the inner wall forming module 300. The first module 310, the second module 320, the third module 410, and the fourth module 420 together enclose a product forming cavity 500. By splitting the outer wall forming module 400 into two modules, the third module 410 and the fourth module 420 can be disassembled along the second direction X to achieve quick demolding. The cross-sectional shape formed by the first module 310 and the second module 320 in the embodiment is a "convex" shape. Of course, the third module 410 and the fourth module 420 can also be designed in other structural shapes, and the first module 310 and the second module 320 can also be designed in other structural shapes, which are determined by the shape of the product to be formed, and are not limited herein. In addition, the outer wall forming module 400 can also be a whole structure, which is not limited herein.

[0045] Please refer to Figure 3 In order to split the melt of the main runner 120 to each branch runner 130, the mold 1000 in the embodiment further includes a split cone 700, which is connected with the second mold plate 200. The split cone 700 is arranged at the end of the main runner 120 away from the melt pool 110, and is used to split the melt flowing into the main runner 120 to the plurality of branch runners 130. The split cone 700 in the embodiment is connected with the second mold plate 200 by a threaded fastener. Of course, the split cone 700 can also be connected with the second mold plate 200 by other means such as clamping and welding, which is not limited herein.

[0046] During the molding process of the mold 1000, gas (such as air or water vapor) may be generated. If the gas in the mold 1000 cannot be effectively discharged, it may form bubbles on the surface of the molded product or produce pores in the molded product, affecting the production quality of the molded product. By arranging the gas channel, the gas generated in the mold 1000 can be discharged from the mold 1000 in time to prevent the product in the mold 1000 from forming defects such as pores, bubbles, and cracks. Moreover, when molten metal mixes with gas, inclusions may be produced, which may adhere to the surface or inside of the casting. By arranging the gas channel, the gas can be effectively discharged to avoid the mixing of gas and molten metal to produce inclusions, thereby improving the overall quality of the molded product. When the gas cannot be discharged in time during the casting process, the expansion of the gas may cause the casting to deform, especially in complex-shaped or thin-walled castings. By arranging the gas channel, the risk of deformation of the molded product can be reduced to ensure the precision of the product.

[0047] Please continue to refer to Figure 3In order to reduce the product defects such as air holes, cracks and the like in the molding process of the mold 1000. The second mold plate 200 in the embodiment is provided with a plurality of first exhaust channels 220, and the plurality of first exhaust channels 220 are arranged one by one corresponding to the plurality of mold cavities 210. Each first exhaust channel 220 is used to communicate the mold cavity 210 and the outside, and is used to exhaust the gas in the mold cavity 210 out of the mold 1000. In addition, in order to realize vacuum suction casting, the mold 1000 in the embodiment further comprises a third mold plate 600, the third mold plate 600 is connected with the second mold plate 200, the third mold plate 600 and the second mold plate 200 are arranged in a stack, and the third mold plate 600 is located away from the first mold plate 100. The second mold plate 200 is provided with a plurality of first exhaust channels 220, and the third mold plate 600 is provided with a second exhaust channel 610. The plurality of first exhaust channels 220 are arranged one by one corresponding to the plurality of mold cavities 210, and each first exhaust channel 220 communicates the mold cavity 210 and the second exhaust channel 610. By connecting the vacuum pump at one end of the second exhaust channel 610 away from the first exhaust channel 220, the inside of the mold 1000 can be vacuumized to realize vacuum suction casting.

[0048] In addition, in order to create a low-pressure environment in the mold 1000, the third mold plate 600 in the embodiment is provided with a vacuum chamber 620, and the vacuum chamber 620 is located between the second exhaust channel 610 and the plurality of first exhaust channels 220. The vacuum chamber 620 can play an important role in the suction casting process. In addition, by providing the vacuum chamber 620 and the second exhaust channel 610, the suction force or viscosity between the molded part and the surface of the mold 1000 can be avoided by the auxiliary action of vacuum, so as to ensure that the part can be demolded more smoothly. Moreover, the vacuum chamber 620 can also more effectively exclude air and gas from the mold 1000, which is crucial for preventing bubbles, air holes or surface defects. By vacuum air exhaust, air is effectively exhausted during the molding process, reducing the influence caused by the gas accumulated in the mold 1000, thereby improving the molding quality.

[0049] The third template 600 is connected with the second template 200, and the third template 600 is connected with the second template 200 by a threaded fastener in the embodiment. Specifically, the third template 600 is provided with a third threaded hole corresponding to the second threaded hole, and the second threaded hole and the third threaded hole are used to install the threaded fastener to connect the second template 200 and the third template 600.
