The injection molding mold device consists of a device body and a molding structure. The molding structure is connected to the device body, and the molding structure is used to mold the product.

[0003] In the prior art, the traditional molding structure includes an upper mold base and a lower mold base. The upper mold base and the lower mold base are detachably connected. The lower mold base is provided with an injection channel and a molding groove. The injection channel is connected to the molding groove. The injection channel is used to introduce the glue into the molding groove so that the molding groove can be used to shape and solidify the glue for molding products, such as the Chinese patent No. CN201721915594.4.

[0004] However, since the molding groove is used to shape and solidify the glue liquid for molding products, the product is respectively abutted against the inner wall of the molding groove and the upper mold base, so that the upper mold base and the inner wall of the molding groove work together to fix the product. During the disassembly and separation of the upper mold base and the lower mold base, the product is separated from the upper mold base, so that the upper mold base can no longer fix the product. At this time, the product is located in the molding groove, and the product is abutted and fixed against the inner wall of the molding groove, that is, the product is only fixed by the inner wall of the molding groove, and the restraining performance of the inner wall of the molding groove alone to fix the product is poor, so that the product is subjected to a smaller fixed restraining force when the mold is opened (that is, the upper mold base and the lower mold base are disassembled and separated), so that the product is more likely to shake in the molding groove when the mold is opened, thereby making the position stability of the product poor when the mold is opened.

[0034] As Figures 1 to 7As shown, the product fixing and forming structure 10 of an embodiment includes an upper die base 100 and a lower die base 200. The upper die base 100 and the lower die base 200 are detachably connected. The upper die base 100 is provided with an upper die cavity 110, and the lower die base 200 is provided with a lower die cavity 210. The upper die cavity 110 and the lower die cavity 210 are communicated with each other to jointly form a forming cavity for forming the product 20.

[0035] Further, the product fixing and forming structure 10 further includes a liquid injection assembly 300, a first forming and pulling assembly 400, and a second forming and pulling assembly 500. The liquid injection assembly 300 is connected to the upper die base 100. The liquid injection assembly 300 is provided with a liquid injection port 310, and the liquid injection port 310 is communicated with the forming cavity. The first forming and pulling assembly 400 is detachably connected to the upper die base 100 and is connected to the lower die base 200. The first forming and pulling assembly 400 is used to fix one end of the product 20. The second forming and pulling assembly 500 is detachably connected to the upper die base 100 and is connected to the lower die base 200. The second forming and pulling assembly 500 is used to fix the other end of the product 20.

[0036] In this embodiment, the first positioning and forming end of the first forming and pulling assembly 400 extends into the forming cavity, and the first positioning and forming end of the first forming and pulling assembly 400 can perform telescopic movement relative to the forming cavity. The second positioning and forming end of the second forming and pulling assembly 500 extends into the forming cavity, and the second positioning and forming end of the second forming and pulling assembly 500 can perform telescopic movement relative to the forming cavity.

[0037] The liquid injection port 310 is used for injecting glue. The liquid injection port 310 is communicated with the forming cavity so that the liquid injection port 310 can inject the glue into the forming cavity. The upper die cavity 110 and the lower die cavity 210 are communicated with each other to jointly form the forming cavity, so that the product 20 abuts against the inner walls of the upper die cavity 110 and the lower die cavity 210 respectively, that is, the product 20 abuts against the inner walls of the upper die base 100 and the lower die cavity 210 respectively.

[0038] The above-mentioned product fixing and forming structure 10. Since the liquid injection assembly 300 is provided with a liquid injection port 310 for injecting glue, the liquid injection port 310 is communicated with the forming cavity so that the liquid injection port 310 is used to inject the glue into the forming cavity, and the glue is shaped and solidified in the forming cavity to form the product 20. The upper mold cavity 110 is communicated with the lower mold cavity 210 to jointly form the forming cavity, so that the product 20 abuts against the inner walls of the upper mold cavity 110 and the lower mold cavity 210 respectively, that is, the product 20 abuts against the inner walls of the upper mold base 100 and the lower mold cavity 210 respectively. Thus, the inner walls of the upper mold base 100 and the lower mold cavity 210 act together to fix the product 20. The first forming and pulling assembly 400 is detachably connected to the upper mold base 100 and is connected to the lower mold base 200. The second forming and pulling assembly 500 is detachably connected to the upper mold base 100 and is connected to the lower mold base 200. During the process of disassembling and separating the upper mold base 100 and the lower mold base 200, the product 20, the first forming and pulling assembly 400 and the second forming and pulling assembly 500 are all separated from the upper mold base 100, so that the upper mold base 100 can no longer fix the product 20. At this time, the product 20 is located in the lower mold cavity 210, and the product 20 abuts against and is fixed by the inner wall of the lower mold cavity 210. The first positioning and forming end of the first forming and pulling assembly 400 extends into the forming cavity, and the first positioning and forming end of the first forming and pulling assembly 400 can move telescopically relative to the forming cavity to fix one end of the product 20. The second positioning and forming end of the second forming and pulling assembly 500 extends into the forming cavity, and the second positioning and forming end of the second forming and pulling assembly 500 can move telescopically relative to the forming cavity to fix the other end of the product 20. Thus, the inner wall of the lower mold cavity 210, the first forming and pulling assembly 400 and the second forming and pulling assembly 500 act together to fix the product 20, thereby solving the problem in the prior art that the product 20 is only fixed by the inner wall of the forming groove. The constraint performance of the inner wall of the lower mold cavity 210, the first forming and pulling assembly 400 and the second forming and pulling assembly 500 acting together to fix the product 20 is better, so that the fixing binding force on the product 20 is greater when the mold is opened (that is, the upper mold base 100 and the lower mold base 200 are disassembled and separated). Thus, it is more difficult for the product 20 to shake in the lower mold cavity 210 under the joint action of the inner wall of the lower mold cavity 210, the first forming and pulling assembly 400 and the second forming and pulling assembly 500 when the mold is opened, and the position stability of the product 20 is better when the mold is opened.

[0047] The present disclosure also provides an injection molding die device, including the product fixing and forming structure 10 of any of the above embodiments.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] Since the liquid injection assembly 300 is provided with a liquid injection port 310 for injecting glue, and the liquid injection port 310 is communicated with the molding cavity so that the liquid injection port 310 is used to inject the glue into the molding cavity, the glue is shaped and solidified in the molding cavity to form the product 20. The upper mold cavity 110 is communicated with the lower mold cavity 210 to jointly form the molding cavity, so that the product 20 abuts against the inner walls of the upper mold cavity 110 and the lower mold cavity 210 respectively, that is, the product 20 abuts against the inner walls of the upper mold base 100 and the lower mold cavity 210 respectively. Thus, the upper mold base 100 and the inner wall of the lower mold cavity 210 jointly act to fix the product 20. The first molding pulling assembly 400 is detachably connected to the upper mold base 100 and is connected to the lower mold base 200. The second molding pulling assembly 500 is detachably connected to the upper mold base 100 and is connected to the lower mold base 200. During the process of disassembling and separating the upper mold base 100 and the lower mold base 200, the product 20, the first molding pulling assembly 400 and the second molding pulling assembly 500 are all separated from the upper mold base 100, so that the upper mold base 100 can no longer fix the product 20. At this time, the product 20 is located in the lower mold cavity 210, and the product 20 abuts against and is fixed by the inner wall of the lower mold cavity 210. The first positioning and molding end of the first molding pulling assembly 400 extends into the molding cavity, and the first positioning and molding end of the first molding pulling assembly 400 can move telescopically relative to the molding cavity so as to fix one end of the product 20 by the first molding pulling assembly 400. The second positioning and molding end of the second molding pulling assembly 500 extends into the molding cavity, and the second positioning and molding end of the second molding pulling assembly 500 can move telescopically relative to the molding cavity so as to fix the other end of the product 20 by the second molding pulling assembly 500. Thus, the inner wall of the lower mold cavity 210, the first molding pulling assembly 400 and the second molding pulling assembly 500 jointly act to fix the product 20, thereby solving the problem in the prior art that the product 20 is only fixed by the inner wall of the molding groove. The inner wall of the lower mold cavity 210, the first molding pulling assembly 400 and the second molding pulling assembly 500 jointly act to fix the product 20 with better constraint performance, so that the product 20 is subjected to a greater fixing binding force when the mold is opened (that is, the upper mold base 100 and the lower mold base 200 are disassembled and separated). Thus, the product 20 is less likely to shake in the lower mold cavity 210 under the joint action of the inner wall of the lower mold cavity 210, the first molding pulling assembly 400 and the second molding pulling assembly 500 when the mold is opened, and the position stability of the product 20 is better when the mold is opened.

[0050] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several variations and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
