When the upper mold 100 and the lower mold 200 are molded together, the convex column 510, the first core shaft 310 and the second core shaft 410 are respectively inserted into the molding groove 610 to jointly form an injection mold cavity of the product.

[0033] Specifically, in the present embodiment, when the handle body is injection molded, the second core shaft 410 is first inserted into the molding groove 610 of the lower mold core 600 by the second core pulling unit 400, and then the upper mold 100 and the lower mold 200 are molded together. During the mold closing process, the protrusion 510 of the upper mold core 500 will be inserted into the molding groove 610 of the lower mold core 600. At the same time, during the movement of the upper mold 100, the first core shaft 310 of the first core pulling unit 300 will also be driven to be inserted into the molding groove 610 of the lower mold core 600. The second core shaft 410, the protrusion 510 and the first core shaft 310 are respectively placed in the molding groove 610, thereby forming an injection mold cavity for molding the handle body, and then injecting molten material into the injection mold cavity to realize injection molding of the handle body. Finally, the two components of the handle body can be integrally injection molded through this production mold, and there is no need to subsequently splice the two components, thereby simplifying the molding process of the handle body and improving the molding efficiency of the handle body.

[0034] In addition, in order to simultaneously perform injection molding on the two components of the handle body, the molding groove 610 in this embodiment includes an upper molding groove 611 and two side molding grooves 612 communicated with the upper molding groove 611, wherein the upper molding groove 611 cooperates with the convex column 510 of the upper mold core 500, one of the side molding grooves 612 cooperates with the first core shaft 310 of the first core pulling unit 300, and the other side molding groove 612 cooperates with the second core shaft 410 of the second core pulling unit 400. Through the upper molding groove 611, the two side molding grooves 612, the convex column 510, the first core shaft 310 and the second core shaft 410, the molding cavity of the handle body is realized, thereby realizing the integrated injection molding of the two components of the handle body.

[0035] Of course, in order to inject molten material into the injection mold cavity, a glue feeding system 120 is provided on the upper mold 100, and the glue feeding system 120 is connected to the injection mold cavity. Glue is injected into the injection mold cavity through the glue feeding system 120, thereby ensuring the injection molding of the handle body. At the same time, in this embodiment, a top plate 210 is provided on the lower mold 200, and a plurality of ejector pins 211 inserted into the injection mold cavity are arranged on the top plate 210. After the handle body is injection molded, the upper mold 100 and the lower mold 200 are opened, and the handle body in the injection mold cavity is ejected by the ejector pin 211, so as to facilitate the demolding of the handle body.

[0036] See also Figure 2 and Figure 3 In order to realize the injection molding of the handle body, the first core pulling unit 300 in this embodiment also includes a driving block 320 and a driving rod 330. The driving block 320 is connected to the upper mold 100, and the driving rod 330 is obliquely arranged on the driving block 320. An inclined driving hole 340 is opened on the first core shaft 310, and the driving hole 340 corresponds to the driving rod 330. The first core shaft 310 is movably arranged on the lower mold 200 and is located on one side of the lower mold core 600.

[0037] When the upper mold 100 and the lower mold 200 are being molded, the upper mold 100 will move with the driving block 320. When the driving block 320 moves, the driving rod 330 will be inserted into the driving hole 340 of the first core shaft 310 and move along the driving hole 340. During the movement of the driving rod 330, the first core shaft 310 will be driven to move, so that the first core shaft 310 is inserted into one of the side molding grooves 612, so as to facilitate the subsequent injection molding of the handle body. Molding; After the handle is injection molded, the upper mold 100 and the lower mold 200 are opened, and the upper mold 100 is reset, and the driving block 320 is reset with it. The driving block 320 then causes the driving rod 330 to be pulled outward from the driving hole 340 of the first core shaft 310. During the process of the driving rod 330 being pulled outward, it also drives the first core shaft 310 to move and pulls the first core shaft 310 out from the side molding groove 612, so as to facilitate the subsequent demolding of the molded handle body.

[0038] See also Figure 3 and Figure 5 Similarly, in order to drive the second mandrel 410 to be inserted into the side molding groove 612 of the lower mold core 600, the second core pulling unit 400 in this embodiment also includes a fixed seat 420 and a driving member 430, the fixed seat 420 is connected to one side of the lower mold 200, and the driving member 430 and the second mandrel 410 are respectively arranged on the fixed seat 420, and the driving member 430 is connected to the second mandrel 410, wherein the driving member 430 can be a cylinder, of course, not limited to the cylinder, but also It can be other driving devices; when the handle body needs to be injection molded, the driving member 430 drives the second core shaft 410 to move, and inserts the second core shaft 410 into the side molding groove 612 of the lower mold core 600, thereby forming an injection mold cavity. After the handle body in the injection mold cavity is injection molded, the driving member 430 drives the second core shaft 410 to be withdrawn from the side molding groove 612 of the lower mold core 600, so as to facilitate the subsequent demolding of the molded handle body and enable the mold to operate reasonably.

[0039] Of course, in order to ensure that the second core shaft 410 can be more stable after being inserted into the side molding groove 612 of the lower mold core 600, in this embodiment, a positioning block 110 is provided on the upper mold 100, and at the same time, a positioning groove 440 is opened on the second core shaft 410. When the handle body is injection molded, the driving member 430 drives the second core shaft 410 to be inserted into the side molding groove 612 of the lower mold core 600, and then the upper mold 100 and the lower mold 200 are molded together. When the upper mold 100 moves to close the mold, it will drive the end of the positioning block 110 to be inserted into the positioning groove 440 of the second core shaft 410, thereby realizing the positioning of the second core shaft 410, thereby avoiding the second core shaft 410 from shaking during injection molding, and improving the injection molding quality of the handle body during injection molding.

[0040] In addition, in the present embodiment, in order to ensure that the second core shaft 410 is accurately positioned when inserted into the side molding groove 612 of the lower mold core 600, a detection switch 450 is provided on the fixed seat 420, and a detection rod 460 is provided on the second core shaft 410. When the driving member 430 drives the second core shaft 410 to be inserted into the side molding groove 612 and reaches the set position, the detection rod 460 will touch the detection switch 450, causing the detection switch 450 to send a signal. Through this signal, it can be ensured that the second core shaft 410 has been inserted into place, thereby making the position of the second core shaft 410 accurate and ensuring the quality of the handle body during injection molding.
