[0036] The following is a further detailed description with reference to the accompanying drawings:

[0037] As attached Figure 1 As shown, an efficient plug injection production mold includes an upper mold 1, a lower mold 2 and an auxiliary positioning mechanism 3.

[0038] As attached Figure 2 As shown, the lower mold 2 is provided with a semi-finished product cavity 21 and a positioning groove 22 , and the lower mold 2 further includes a limiting column 23 .

[0039] There are multiple semi-finished product cavities 21 , which are recorded as 6 in this example. The semi-finished product cavities 21 are distributed side by side on the surface of the lower mold 2 , and one side of the semi-finished product cavities 21 is connected to the positioning groove 22 .

[0040] The positioning groove 22 is in a columnar shape, with both ends passing through the lower mold 2 , and the arrangement direction of the semi-finished product cavity 21 is parallel to the slotting direction of the positioning groove 22 .

[0041] As attached Figure 3 As shown, the auxiliary positioning mechanism 3 includes a tooling die 31 , a handle 32 and an external plate 33 .

[0042] As attached Figure 4 As shown, the tooling mold 31 includes a base 311 and a tooling strip 312. Two threaded posts 3112 are fixed to the ends of the base 311. A groove 3113 for mounting the tooling strip 312 is formed on one side of the base 311. This side is referred to as the mounting side, and the opposite back side is referred to as the base limiting side. A limiting groove 3111 is also formed on the mounting side.

[0043] The tooling strip 312 fits into the groove 3113 of the base 311, and there are four holes at the four corners of the tooling strip 312, which are connected and fixed to the base 311 by hexagon socket bolts. At the same time, the tooling strip 312 has evenly distributed sockets 3121 on the side facing away from the base.

[0044] As attached Figure 5 and attached Figure 6 As shown, when the tooling mold 31 fits into the positioning groove 22, the groove wall of the positioning groove 22 fits with the base limiting side of the tooling mold 31, and the limiting column 23 is plugged into the limiting groove 3111 to fix the position of the base 3111 to prevent it from moving.

[0045] As attached Figure 4 As shown, a fixing threaded hole 321 is opened at one end of the handle 32, and the fixing threaded hole 321 is threadedly connected to the threaded columns 3112 at both ends of the base 311. At the same time, the material of the handle 32 is heat-resistant material for isolating high temperature, which is rubber here.

[0046] As attached Figure 7As shown, there are two external plates 33, one fixed to each side of the lower mold 2. A placement slot 332 is defined on the upper edge of each external plate 33. The placement slot 332 intersects both ends of the positioning slot 22. The upper edge of the placement slot 332 is provided with an inclined sidewall. When the tooling 31 is inserted into the positioning slot 22, the lower end of the tooling 31 first contacts the inclined sidewall of the placement slot 332. The inclined sidewall acts as a guide, allowing the tooling 31 to fit more easily into the positioning slot 22.

[0047] At the same time, one side of the external plate 33 extends away from the lower mold 2 to form a placement rack 331 , and a placement groove 3311 is formed on the upper edge of the placement rack 331 . The bottoms of the placement grooves 3311 of the external plates 33 on both sides are flush.

[0048] After the injection molding process is completed, the tooling mold 31 can be temporarily placed in the placement groove 3311 to facilitate the cooling of the tooling mold 31 and the workers to remove the finished plug and put a new semi-finished plug.

[0049] The usage process of this embodiment:

[0050] Before the injection molding process, the tooling mold 31 is removed from the lower mold 2, and the semi-finished plug is plugged into the socket 3121 on the side of the tooling strip 312. After the plugging is completed, hold the handles 32 at both ends of the tooling mold 31, and make the lower end of the tooling mold 31 contact the inclined side wall of the placement groove 332, and gradually lower it so that the tooling mold 31 fits and fits into the positioning groove 22. The inclined side wall plays a guiding role, so that the tooling mold 31 can fit and fit into the positioning groove 22 more easily. At the same time, the limit column 23 is plugged into the limit groove 3111 to prevent the tooling mold 31 from moving. The semi-finished plugs plugged into the tooling strip 312 are placed one by one into the semi-finished cavity 21 opened on the surface of the lower mold 2.

[0051] Start the injection molding machine, close the upper mold 1 and the lower mold 2, and start injection molding.

[0052] After the injection molding process is complete, the handles 32 at each end of the tooling mold 31 are held, and the lower end of the tooling mold 31 is brought into contact with the inclined sidewalls of the placement slot 3311. The tooling mold 31 is then gradually lowered so that it fits snugly into the placement slot 3311. This facilitates cooling of the tooling mold 31, allowing workers to remove finished plugs and replace them with new semi-finished plugs. Simultaneously, another batch of tooling molds 31, after having been inserted into the semi-finished plugs, are fitted into the positioning slots 22 on the surface of the lower mold 2. This allows multiple semi-finished plugs to be injection molded at once, improving the efficiency of the plug injection molding process.

[0053] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of protection required by this application, they are protected by patent law.
