[0035] In related technologies, when molds are used to form different products with different structures, it is often necessary to develop multiple sets of different molds for multiple different products, or to develop multiple sets of different mold cores for different products. This results in high development costs, long development cycles, and affects the production efficiency of the products.

[0036] In view of this, the present disclosure provides a mold core for molds. When molding different products with different structures, a set of the mold cores disclosed herein can reduce development costs and development cycles, and improve the production efficiency of multiple different products.

[0037] Figure 1 This is a schematic diagram of the structure of a mold core for a mold according to a first embodiment of the present disclosure. The mold core 100 for a mold of the present disclosure includes a plurality of mold core portions. The plurality of mold core portions are combined to form the mold core 100 to form the profile of the outer wall of the mold core 100 and / or the profile between the mold core portions. At least one of the mold core portions is detachably disposed to allow for disassembly / reassembly to change the local structure of the profile.

[0038] In some examples, multiple mold core portions include a retaining portion 111 and a replacement portion 112. The end of the replacement portion 112 is detachably connected to the retaining portion 111, and the outer peripheral surface of the replacement portion 112 forms the profile of the outer wall of the mold core 100, with a profile structure 1121 on the outer peripheral surface. In other words, the profile of the outer wall of the mold core 100 includes the outer peripheral surface of the replacement portion 112. The outer peripheral surface structure of the replacement portion 112 forms a partial structure of the profile of the outer wall of the mold core 100. Therefore, when the replacement portion 112 is removed and replaced with a different replacement portion 112 with a different outer peripheral surface structure, the partial structure of the entire profile of the mold core 100 also changes. Thus, by making the mold core 100 partially replaceable, the mold core 100 can be used to mold different products with different structures, with low development costs and short development cycles, which is beneficial for improving the production efficiency of multiple different products.

[0039] Optionally, the retained portion 111 and the replacement portion 112 are fixedly connected to form a one-sided mold core 11.

[0040] Thus, when the retained portion 111 is pulled laterally out of the product, for example, along... Figure 1When the molded product is pulled out to the right in the state shown, the replacement part 112 can move along with the lateral pulling motion of the retaining part 111, thereby detaching from the molded product and facilitating product demolding. Of course, it is understood that the retaining part 111 and the replacement part 112 can also form other types of mold cores 100, all of which are within the scope of protection of this application.

[0041] In other examples, multiple core portions are joined together to form a single core. For example, two or more core portions are joined together to form a single core. Thus, by removing or installing core portions—for example, removing or installing a single core portion located at the beginning or end—the number of core portions is changed, thereby altering the local structure of the core surface formed by the joining, resulting in various different cores.

[0042] Figure 2 This is a schematic cross-sectional view of the mold core 100 portion as disclosed herein. See also... Figure 2 The mold core 100 further includes a connecting shaft 113 and a fastening shaft 114. The connecting shaft 113 is connected to the retained portion 111 and the replacement portion 112 respectively, and the portion of the connecting shaft 113 located inside the retained portion 111 has a radially through connecting hole 1131. The fastening shaft 114 is detachably fastened to the retained portion 111 and passes through the connecting hole 1131. Thus, when the fastening shaft 114 is fastened to the retained portion 111 and passes through the connecting shaft 113, the retained portion 111 and the replacement portion 112 are connected together, thereby realizing the installation between the retained portion 111 and the replacement portion 112. When the fastening shaft 114 is disassembled from the retained portion 111 and disengaged from the connecting hole 1131 of the connecting shaft 113, the retained portion 111 and the replacement portion 112 are separated, thereby realizing the disassembly between the retained portion 111 and the replacement portion 112.

[0043] Optionally, the fastening shaft 114 is a fastening bolt for threaded fastening inside the retained portion 111. The connecting shaft 113 includes a connecting pin for fitting inside the retained portion 111 and the replacement portion 112. Thus, after the connecting pin is installed into the retained portion 111 and the replacement portion 112, the threaded installation / removal of the fastening bolt enables the installation and removal of the retained portion 111 and the replacement portion 112, and the installation and removal of the retained portion 111 and the replacement portion 112 are convenient.

[0044] Optionally, there may be multiple replacement portions 112, and the multiple replacement portions 112 may have different surface structures 1121. It is understood that the multiple replacement portions 112 may include two or more replacement portions 112.

[0045] Figure 3 This is a schematic diagram of the structure of a mold core for a mold according to the second embodiment of this disclosure. (See also...) Figure 3 The plurality of replacement portions 112 may include a first replacement portion 112a, a second replacement portion 112b, and a third replacement portion 112c. The outer peripheral surface of the first replacement portion 112a is provided with a first surface structure 1121a. The outer peripheral surface of the second replacement portion 112b is provided with a second surface structure 1121b. The outer peripheral surface of the third replacement portion 112c is provided with a third surface structure 1121c. Furthermore, the structures of the first surface structure 1121a, the second surface structure 1121b, and the third surface structure 1121c are different from each other.

[0046] Therefore, when the mold core 100 having the first replacement portion 112a is used in a mold, the mold can form a first product having a first inner peripheral wall structure. When the first replacement portion 112a is removed from the retained portion 111 and replaced with the second replacement portion 112b, and the mold core 100 having the second replacement portion 112b is used in a mold, the mold can form a second product having a second inner peripheral wall structure. When the first replacement portion 112a is removed from the retained portion 111 and replaced with the third replacement portion 112c, and the mold core 100 having the third replacement portion 112c is used in a mold, the mold can form a third product having a third inner peripheral wall structure. Furthermore, since the structures of the first surface structure 1121a, the second surface structure 1121b, and the third surface structure 1121c are different from each other, the first inner peripheral wall structure, the second inner peripheral wall structure, and the third inner peripheral wall structure formed corresponding to the first surface structure 1121a, the second surface structure 1121b, and the third surface structure 1121c are also different from each other. Therefore, one set of mold core 100 can be used to form multiple different products with different structures, and the development cost and development cycle of the mold core 100 are low.

[0047] Optionally, the multiple surface structures 1121 differ in that they have the same shape but different dimensions. For example, the multiple surface structures 1121 include multiple forming grooves disposed on the outer peripheral surface of the multiple replacement portions 112. The multiple forming grooves have the same shape but different dimensions. Of course, it is understood that the multiple surface structures 1121 may also have different shapes and different dimensions, all of which are within the scope of protection of this application.

[0048] Optionally, the plurality of replacement portions 112 include a plurality of main body portions for correspondingly setting the plurality of surface structures 1121. The plurality of main body portions have the same structure. Thus, the plurality of replacement portions 112 differ only in the size of the surface structures 1121, with small differences in structural parameters, which facilitates the assembly of the mold core 100 having the replacement portions 112 into the mold.

[0049] Optionally, the mold core 100 further includes a second side mold core 12. The second side mold core 12 is spaced apart from and opposite to the replacement portion 112, and the end face of the second side mold core 12 facing the first side mold core 11 is formed as a profile between the mold core portions. Furthermore, the second side mold core 12 is movably positioned closer to / away from the replacement portion 112. Thus, the second side mold core 12 can be used to mold the end face of the product and can smoothly move away from the product after molding.

[0050] Figure 4 This is a schematic diagram of the structure of the mold according to an embodiment of the present disclosure. Figure 5 This is a cross-sectional view of a mold according to an embodiment of this disclosure. See also... Figure 4 and Figure 5 The mold provided in this disclosure includes a first mold base 81, a second mold base 82, and a mold core 100 as described in any of the above embodiments. The second mold base 82 is opposite to and spaced apart from the first mold base 81. The mold core 100 is disposed between the first mold base 81 and the second mold base 82, and is used to cooperate with the first mold base 81 and the second mold base 82 to form a molding cavity 83 for molding a product. With the mold of this disclosure, when the replacement portion 112 of the mold core 100 is replaced, one set of molds can be used to produce different products, which helps to reduce the development cost and development cycle of the mold when producing multiple different products.

[0051] Optionally, the first mold base 81 and the second mold base 82 are arranged vertically at intervals so that they can move closer to or further away from each other when at least one of the first mold base 81 and the second mold base 82 moves up and down.

[0052] Optionally, the first mold base 81 is fixedly disposed. The second mold base 82 is movable toward / away from the first mold base 81, used to cooperate with the mold core 100 to form the closed molding cavity 83 when the two are close to each other, and to expose the molded product when the first mold base 81 and the second mold base 82 are far apart, so as to facilitate the demolding of the product. However, it is understood that the second mold base 82 may also be fixedly disposed, and the first mold base 81 may be movable toward / away from the second mold base 82. Alternatively, both the second mold base 82 and the first mold base 81 may be movable.

[0053] Optionally, the mold further includes an ejector 84. The ejector 84 extends movably through the first mold base 81 into the region where the mold core 100 is located, for ejecting the product detached from the mold core 100. Thus, after the second mold base 82 moves away from the first mold base 81, and the first side mold core 11 and the second side mold core 12 move away from each other to be laterally extracted and detached from the molded product, the ejector 84 moves to eject the product and detach it from the fixed first mold base 81, thereby achieving smooth demolding of the product. For example, the ejector 84 includes one or more ejector rods. After the mold core 100 detaches from the product, one or more of the ejector rods eject the product from the first mold base 81, thereby achieving complete demolding of the product.

[0054] Optionally, the mold further includes a driving member 85 and a guide member 86. The driving member 85 is connected to the ejector 84 and is used to drive the ejector 84 to move. The guide member 86 passes through the driving member 85 and extends along the moving direction of the driving member 85, and is used to guide the movement of the driving member 85. Thus, when the driving member 85 drives the ejector 84 to move to eject the product, the guide member 86 can guide the movement of the driving member 85 and the ejector 84, thereby allowing the driving member 85 and the ejector 84 to move along the extending direction of the guide member 86. For example, the driving member 85 includes a driving plate. The guide member 86 includes a guide post. Thus, when the plate-shaped driving member 85 drives multiple ejector rods to move to eject the product, the driving member 85 and the multiple ejector rods can move along the extending direction of the guide post.

[0055] Optionally, the mold further includes a drive assembly 87. The drive assembly 87 includes a first drive member 871 (e.g., a first cylinder) and a second drive member 872 (a second cylinder). The first drive member 871 is connected to the retaining portion 111 and drives the retaining portion 111 to slide on the first mold base 81. The second drive member 872 is connected to the second side mold core 12 and drives the second side mold core 12 to slide on the first mold base 81, thereby allowing the first side mold core 11 and the second side mold core 12 to slide closer together or further apart.

[0056] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
