Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a hinge injection mold. Background Technology

[0002] Injection molds are specialized tools used in plastic injection molding processes. They mainly consist of high-precision molds and mold supports. By injecting heated and molten plastic into the mold cavity and then cooling and solidifying it, plastic products of the required shape and size are obtained. They are widely used in the manufacture of various fields such as automotive parts, electronic casings, home appliances, and toys.

[0003] In the current injection molding process, the mold needs to undergo the injection of high-temperature molten liquid and subsequent cooling and solidification. This drastic temperature change will cause thermal expansion and contraction of the mold material, resulting in internal stress in different parts. This can lead to damage such as micro-cracks on the surface of the mold cavity, which can easily cause inaccurate dimensions or rough surfaces after the hinge is injection molded, thus affecting the quality and performance of the product.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1-5 As shown, this application provides a hinge injection mold, which includes a mold body 1 and an injection mold area 2 disposed on the mold body 1;

[0026] Specifically, such as Figure 3 As shown, a fixing component 3 is provided on the top of the mold body 1. The mold body 1 is used to fix the injection mold area 2. The mold body 1 includes a fixing plate 302, which is rotatably connected to the top of the mold body 1 and snapped onto the top of the injection mold area 2. A clamping plate 303 is provided on the side wall of the fixing plate 302. By setting the movable injection mold area 2 inside the mold body 1 and setting the fixing component 3 on the top of the mold body 1, the injection mold area 2 can be disassembled and assembled by rotating the fixing plate 302 on the fixing component 3. This facilitates the replacement of the worn and rough injection mold area 2 and improves the molding quality of the mold.

[0027] The top of the adjusting rod 401 is fixedly connected to the shaft 301, and the fixing plate 302 is rotatably connected to the outer peripheral wall of the shaft 301.

[0028] Specifically, such as Figure 4As shown, the outer peripheral wall of the shaft 301 has multiple sets of slots 3061. The side wall of the clamping plate 303 is fixedly connected to the clamping rod 306. The clamping rod 306 is inserted into the slot 3061. By pressing the upper end of the clamping plate 303, the clamping plate 303 will rotate on the connector 304. At the same time, the clamping rod 306 at the lower end of the clamping plate 303 will slide out of the slot 3061. At this time, the fixing plate 302 can be rotated until the fixing plate 302 is engaged with the top of the injection molding area 2, thus fixing the injection molding area 2.

[0029] A connector 304 is fixedly connected to the side wall of the fixed plate 302. A clamping plate 303 passes through the side wall of the connector 304. A spring 305 is fixedly connected to the side wall of the shaft 301. The spring 305 is fixedly connected to the clamping plate 303. After the clamping plate 303 is released, the spring force of the spring 305 can reset the clamping plate 303. At the same time, the clamping rod 306 on the clamping plate 303 will be inserted into the clamping slot 3061 for fixation, thus preventing the fixed plate 302 from rotating at will.

[0030] Specifically, such as Figure 5 As shown, an adjustment component 4 is provided between the fixed component 3 and the mold body 1. The adjustment component 4 is used to move the fixed component 3. The adjustment component 4 includes an adjustment rod 401, which is movably inserted into the top of the mold body 1. A round rod 402 is slidably connected inside the adjustment rod 401 and is inserted into the inside of the mold body 1.

[0031] The shaft 301 and the adjusting rod 401 are internally threaded with a lead screw 403. The bottom of the shaft 301 is rotatably connected to a wedge 404. The wedge 404 slides up and down inside the adjusting rod 401. By rotating the lead screw 403 downward, the wedge 404 can be moved downward. At the same time, the four sets of round rods 402 slide on the side wall of the wedge 404 and retract inside the adjusting rod 401. At this time, the height of the adjusting rod 401 can be moved up and down, which is convenient for adjustment according to the height of different injection mold areas 2, thus increasing its applicability.

[0032] The round rod 402 is slidably connected to the side wall of the wedge-shaped part 404, and the round rod 402 passes through the side wall of the adjusting rod 401.

[0033] The top of the mold body 1 has multiple sets of adjustment grooves 4011. Adjustment rods 401 are slidably connected inside the adjustment grooves 4011. Multiple sets of circular grooves 4021 are opened on the inner wall of the adjustment grooves 4011. Circular rods 402 are inserted into the circular grooves 4021. By rotating the lead screw 403 upward, the wedge-shaped part 404 can be driven to move upward. At the same time, the four sets of circular rods 402 will slide on the side wall of the wedge-shaped part 404 and be inserted into the circular grooves 4021 for fixation.

[0034] The specific steps of this solution are as follows: First, the new injection mold area 2 is assembled on the top of the mold body 1. Then, by rotating the lead screw 403 downward, the wedge-shaped part 404 can be moved downward. At the same time, the four sets of round rods 402 will slide on the side wall of the wedge-shaped part 404 and retract inside the adjusting rod 401. At this time, the height of the adjusting rod 401 and the fixing plate 302 can be moved downward. Next, by pressing the upper end of the clamping plate 303, the clamping rod 306 at the lower end of the clamping plate 303 will slide out of the clamping groove 3061. Then, the fixing plate 302 is rotated until the fixing plate 302 is clamped on the top of the injection mold area 2 for fixation. Finally, the injection mold area 2 is filled with injection molding.
