[0021] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0024] Thermoplastic carbon fiber (CCF) is a carbon fiber composite material with comprehensive properties such as high strength, high modulus, heat resistance, wear resistance, corrosion resistance, and chemical resistance. It is a composite material composed of a thermoplastic resin matrix and carbon fiber-reinforced thermoplastic resin. Currently, CCF is widely used in precision instrument components, electronics, automobiles, machinery, aerospace, and other fields, and is increasingly being adopted by more and more industries and products. In practical applications, thermoplastic carbon fiber is typically processed using a hot-pressing process to obtain the final product.

[0025] However, in the traditional hot pressing process using molding dies, the product is usually placed into the mold. After hot pressing is completed, the mold needs to be opened, the fixing screws need to be removed, and then the male mold core needs to be removed using an auxiliary fixture. The male mold core is then placed into a material handling fixture, the molding insert descends, and the product is removed. The operation steps are complicated, resulting in low production efficiency.

[0026] Therefore, in order to solve the above-mentioned technical problems, the embodiments of this application provide a molding die. By using a plurality of first elastic elements to connect the support plate and the second connecting part, and by using a plurality of second elastic elements to connect the moving component and the bottom of the cavity, when the mold is opened, the elastic force of the first elastic elements can lift the support plate carrying the thermoformed product, and the elastic force of the second elastic elements can lift the moving component and the molding insert. The thermoformed product can be taken out without the aid of tools. The operation steps are simple and the production efficiency is improved.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please see Figures 1 to 3As shown. One embodiment of this application provides a molding die 100. The molding die 100 includes a male mold core 20 and a female mold core 10 that can be engaged with the male mold core 20. The male mold core 20 has a cavity 21. The molding die 100 also includes a base 30, a support plate 40, a moving component 60, and a molding insert 80. The base 30 is housed within the cavity 21. The base 30 includes a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is connected to the bottom of the cavity 21, and a mounting cavity 310 is provided on the side of the first connecting portion 31 near the bottom of the cavity 21. The support plate 40 is housed within the cavity 21, and the support plate 40 is connected to the second connecting portion 32 by a plurality of first elastic members 50. A receiving groove 41 is provided on the side of the support plate 40 away from the second connecting portion 32. The receiving groove 41 is used to hold the product. The movable component 60 is installed in the mounting cavity 310, and the movable component 60 is connected to the bottom of the cavity 21 through a plurality of second elastic elements 70. The molding insert 80 is disposed on the base 30, and one end of the molding insert 80 is movably inserted through the support plate 40, and the other end of the molding insert 80 is connected to the movable component 60. When the mold is opened, the female mold core 10 moves away from the male mold core 20, and the first elastic element 50 and the second elastic element 70 automatically return to their original positions. The elastic force of the first elastic element 50 lifts the support plate 40, so that there is a first gap between the support plate 40 and the second connecting part 32, and the elastic force of the second elastic element 70 lifts the movable component 60 and the molding insert 80, so that there is a second gap between the movable component 60 and the bottom of the cavity 21, wherein the first gap is larger than the second gap.

[0029] In some embodiments of this application, the molding die 100 uses a plurality of first elastic elements 50 to connect the support plate 40 and the second connecting part 32, and a plurality of second elastic elements 70 to connect the moving component 60 and the bottom of the cavity 21. When the mold is opened, the elastic force of the first elastic elements 50 can lift the support plate 40 carrying the thermoformed product, and the elastic force of the second elastic elements 70 can lift the moving component 60 and the molding insert 80. The thermoformed product can be taken out without the aid of tools, the operation steps are simple, and the production efficiency is improved.

[0030] Understandably, when the molding die 100 is closed, the first elastic member 50 is compressed by the support plate 40 to make the support plate 40 and the second connecting part 32 abut against each other, and the second elastic member 70 is compressed by the moving component 60 driven by the molding insert 80 to make the moving component 60 abut against the bottom of the cavity 21. This can ensure the flatness of the product after hot pressing and improve the product yield.

[0031] Understandably, during mold opening, the elastic force of the second elastic member 70 can lift the moving component 60 and the molding insert 80 by a second gap distance, and the elastic force of the first elastic member 50 can lift the support plate 40 by a first gap distance. If the product is ejected from the support plate 40, the first gap distance of the support plate 40 needs to include the second gap distance, the thickness of the product, and a preset material removal stroke. Therefore, the first gap is greater than the second gap. By setting the first gap to be greater than the second gap, it can be ensured that the support plate 40 carrying the product is ejected to a position that facilitates product removal, thereby improving product production efficiency.

[0032] In some embodiments of this application, the cross-section of the first connecting portion 31 gradually decreases along the direction extending from the first connecting portion 31 away from the second connecting portion 32, which facilitates the smooth installation of the base 30 into the cavity 21 of the male mold core 20 and improves the assembly and disassembly efficiency of the base 30 and the male mold core 20.

[0033] Understandably, the inner side of the cavity 21 of the male mold core 20 includes a contact surface that contacts the first connecting portion 31, and the shape of the contact surface is adapted to the shape of the outer side of the first connecting portion 31.

[0034] In some embodiments of this application, the sides of the first connecting part 31 are rounded. By setting the outer side of the first connecting part 31 as a rounded surface and adapting it to the inner side of the cavity 21 of the male mold core 20, the base 30 can be installed more smoothly in the cavity 21 of the male mold core 20, which further improves the assembly and disassembly efficiency of the base 30 and the male mold core 20.

[0035] In some embodiments of this application, the bottom of the receiving groove 41 is provided with a hollow portion 410 that is consistent with the shape of the product, which is beneficial for placing the product before molding and ensuring the stability of the shape of the product after molding.

[0036] In some embodiments of this application, the female mold core 10 is provided with a contact portion 11. The contact portion 11 includes a first contact surface 110 and a second contact surface 111. When the mold is closed, the first contact surface 110 contacts the side of the support plate 40 near the base 30, and the second contact surface 111 contacts the bottom of the receiving groove 41.

[0037] In some embodiments of this application, during mold closing, the second contact surface 111 first contacts the bottom of the receiving groove 41, and then the first contact surface 110 contacts the side of the bearing plate 40 near the base 30. By setting a height difference between the first contact surface 110 and the second contact surface 111, a stepped structure can be formed. On the one hand, reverse installation or misalignment can be avoided during the engagement of the male mold core and the female mold core. On the other hand, during the pressing of the product, the stepped structure can disperse the stress concentration area to ensure the flatness of the molded product, improve the yield of the processed product, and thus improve production efficiency.

[0038] In some embodiments of this application, the molding die 100 further includes an annular seal 92. The contact portion 11 is provided with an annular sealing groove 112. The annular seal 92 surrounds the annular sealing groove 112. The annular seal 92 is used to seal the third gap between the male mold core 20 and the female mold core 10.

[0039] In some embodiments of this application, sealing the third gap between the male mold core 20 and the female mold core 10 facilitates the following: In some embodiments of this application, the molding insert 80 includes a plurality of first molding inserts 81 and a plurality of second molding inserts 82. The moving assembly 60 includes a moving plate 61 and a fixed plate 62. The fixed plate 62 is mounted on the side of the moving plate 61 away from the bottom of the cavity 21. The first molding inserts 81 movably pass through the fixed plate 62 and are connected to the moving plate 61. The second molding inserts 82 movably pass through the fixed plate 62 and are connected to the fixed plate 62.

[0040] In some embodiments of this application, the first molding insert 81 may be the same as or different from the second molding insert 82. This embodiment does not impose any restrictions. For example, the first molding insert 81 and the second molding insert 82 may be set according to the shape of the product.

[0041] In some embodiments of this application, the fixed plate 62 is provided with a sliding groove for the first molding insert 81 and the second molding insert 82 to slide. By splitting the entire molding insert 80 into the first molding insert 81 and the second molding insert 82, and by connecting the first molding insert 81 to the moving plate 61 through the sliding groove, and the second molding insert 82 to the fixed plate 62 through the sliding groove, the local stress of the molding insert 80 is effectively dispersed, ensuring the flatness of the product after hot pressing.

[0042] Understandably, each first molding insert 81 and each second molding insert 82 is an independent molding insert 80. On the one hand, this facilitates the replacement and disassembly of the molding insert 80, reduces maintenance costs, and extends the service life of the molding die 100. On the other hand, because the manufacturing and installation of each molding insert 80 are precisely controlled, product defects caused by assembly errors can be reduced, and the yield of the molded product can be improved.

[0043] In some embodiments of this application, the fixing plate 62 has a plurality of first engaging portions 620 around its perimeter near the moving plate 61. The second molding insert 82 has second engaging portions 820 corresponding to the plurality of first engaging portions 620. The second engaging portions 820 can abut against the first engaging portions 620.

[0044] In some embodiments of this application, the second molding insert 82 extends into the sliding groove from the side of the fixed plate 62 near the moving plate 61 until the second locking part 820 can abut against the first locking part 620. The abutment between the second locking part 820 and the first locking part 620 helps to fix the second molding insert 82 on the fixed plate 62 and ensures the stability of the position of the second molding insert 82.

[0045] In some embodiments of this application, the first molding insert 81 passes sequentially through the base 30 and the fixed plate 62 from the side of the base 30 away from the moving plate 61 until it abuts against the moving plate 61. This can fix the moving plate 61 to the first molding insert 81, which helps to ensure the stability of the position of the first molding insert 81.

[0046] In some embodiments of this application, by fixing the second molding insert 82 and the first molding insert 81 to the fixed plate 62 and the moving plate 61 respectively, the local stress of the first molding insert 81 and the second molding insert 82 is effectively dispersed, ensuring the flatness of the product after hot pressing. This improves the yield of the molded product.

[0047] In some embodiments of this application, the molding die 100 further includes a plurality of locking members 90. The locking members 90 are used to lock and fix the support plate 40 and the base 30.

[0048] In some embodiments of this application, before the male mold core 20 and the female mold core 10 are engaged, the bearing plate 40 and the base 30 are locked by the locking member 90, so that several first elastic members 50 are in a compressed state, avoiding the problem of inaccurate hot pressing due to the male mold core 20 and the female mold core 10 not being tightly engaged, thus ensuring the yield of the product after hot pressing; after hot pressing is completed, the male mold core 20 and the female mold core 10 are opened, and the elastic force of the second elastic member 70 lifts the molding insert 80, the moving plate 61 and the fixed plate 62, and the locking member 90 is further removed. The bearing plate 40 carrying the product is lifted by the elastic force of the first elastic member 50, and the product can be directly taken out. The product after hot pressing can be taken out without the aid of tools, the operation steps are simple, and the production efficiency is improved.

[0049] In some embodiments of this application, the molding die 100 further includes a limiting rod 91. The support plate 40 has a plurality of first holes 42 around its perimeter. The second connecting portion 32 has a plurality of second holes 320 around its perimeter, each corresponding to one of the first holes 42. One end of the limiting rod 91 extends through the first hole 42 to the second hole 320. The limiting rod 91 is used to limit the distance the support plate 40 is ejected, which helps prevent the support plate 40 from being ejected from the male mold core 20 by the first elastic element 50, causing the product to fall off the support plate 40 and be damaged, thus improving the product yield and production efficiency.

[0050] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
