DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , 2 As shown in Figures 3, 4 and 5, the utility model provides a technical solution: a die-casting mold that is easy to disassemble, comprising: a bottom template 1 with a plurality of limit grooves 7 symmetrically opened on the top; a movable slider 14 is slidably installed inside the limit groove 7, and a top pressure plate 15 is fixedly connected to the top of the movable slider 14; a die core 10 is placed on the top of the bottom template 1, a head circular plate is welded to the bottom of the die core 10, and the top pressure plate 15 presses the circular plate to fix the die core 10, and a worm wheel ring 8 is rotatably connected to the outer side of the die core 10, and the worm wheel ring 8 slides on the top of the bottom template 1, and a worm 13 is meshedly connected to the outer side of the worm wheel ring 8, and an extrusion inclined plate 9 is equidistantly welded on the inner side of the worm wheel ring 8, and when the worm wheel ring 8 rotates, the inclined surface of the extrusion inclined plate 9 extrudes the movable slider 14, which is used for rotating and extruding the movable slider 14 to move; a top template 3 is placed above the bottom template 1, and a convex core 5 cooperating with the die core 10 is installed on the bottom of the top template 3 by bolts.

[0026] It should be noted that when the utility model needs to replace the die core 10, the ratchet wrench drives the worm 13 to rotate, and the worm 13 drives the worm wheel ring 8 to rotate, so that the extrusion inclined plate 9 is separated from the movable slider 14, and the movable slider 14 is slid to one end of the limiting groove 7. When the top pressure plate 15 is in contact with the bottom of the die core 10, the die core 10 is removed, and the new die core 10 is placed on the top of the bottom template 1. The worm gear ring 8 is driven by the worm 13 to rotate, and the worm wheel ring 8 drives the extrusion inclined plate 9 to squeeze the movable slider 14, so that the movable slider 14 drives the top pressure plate 15 to buckle on the bottom of the die core 10, so as to fix the die core 10, and the driving The worm 13 can realize the rapid disassembly of the die core 10. By using the rotating mechanism of the worm and the worm wheel, the extrusion inclined plate and the movable slider can be quickly separated, so that the die core can be easily removed and replaced; the die core is pressed tightly by the top pressure plate, combined with the limiting and positioning of the positioning column 11, the die core can be firmly fixed; since the replacement and fixation of the die core mainly rely on the transmission of the worm wheel and the sliding of the movable slider, the pressure can be effectively dispersed, the direct mechanical wear is reduced, and the service life of the mold is extended; the entire disassembly and fixing process only needs to drive the worm to complete, without the need for frequent rotation of the bolts, so that the operator can quickly complete the disassembly.

[0027] See also Figure 5 As shown, the limiting groove 7 is a concave structure, the bottom of the movable slider 14 is a convex structure matched with the limiting groove 7, and the top pressure plate 15 is an isosceles trapezoidal structure, and the inclined surface of the isosceles trapezoidal structure is vertically arranged.

[0028] It should be noted that the concave limiting groove 7 and the convex moving slider 14 of the utility model: the limiting groove 7 of the concave structure cooperates with the moving slider 14 of the convex structure, so that it can better guide the position of the moving slider 14 and ensure its accurate movement during the movement of the moving slider 14. When the die core 10 needs to be replaced, the accurate structural matching can make the replacement work faster and safer, and prevent the moving slider 14 from detaching when the top pressure plate 15 is squeezed. The top pressure plate 15 adopts a waist trapezoidal structure, and its inclined surfaces are vertically arranged so that the inclined surfaces are respectively located at the top and the bottom, which can more effectively disperse the pressure on the die core 10. The waist trapezoidal structure presses the die core 10 through its inclined surfaces. The more the top pressure plate 15 moves toward the die core 10, the greater the pressure it causes, so that the top pressure plate 15 can fix the die core 10 more firmly, and it is also convenient to adjust the clamping force as needed to adapt to different pressure requirements.

[0029] See also Figure 3 , 4 As shown, a limit block 12 of an inverted L-shaped structure is fixedly connected to the top of the bottom template 1, the worm wheel ring 8 is slidably installed inside the limit block 12, the worm 13 is rotatably installed inside one of the limit blocks 12, a plurality of positioning columns 11 are fixedly connected to the top of the bottom template 1, and a positioning hole cooperating with the positioning column 11 is provided at the bottom of the die core 10.

[0030] It should be noted that the positioning column 11 and the limiting block 12 of the utility model are all equidistantly fixedly installed with the center of the circle of the die core 10 as the center. The four limiting blocks 12 restrict the worm wheel 8 so that the worm wheel 8 can only rotate around the center of the die core 10, and the limiting groove 7 is also symmetrically arranged with the center of the circle of the die core 10 as the center, so that when the worm wheel 8 rotates, the extrusion inclined plate 9 and the movable slider 14 can be correspondingly extruded and matched, so that the movable slider 14 can move toward the middle at the same time to quickly complete the extrusion and fixation. The positioning of the die core 10 by the positioning column 11 makes the center of the die core 10 of different specifications remain unchanged, so that the centers of the die core 10, the bottom template 1, and the worm wheel 8 are concentric, which facilitates the cooperation of the extrusion inclined plate 9 and the movable slider 14 to achieve fixation.

[0031] See also Figure 1 , 2As shown, the four corners of the top of the bottom template 1 are fixedly connected with guide columns 2, the top template 3 is slidably connected to the outside of the guide column 2, the top of the guide column 2 is fixedly connected with a top plate 4, the top of the top plate 4 is fixedly connected with a hydraulic cylinder 18, the output end of the hydraulic cylinder 18 is fixedly connected to the top template 3, the outside of the top template 3 is slidably connected with a transparent cover 6, a limiting slide groove 17 is provided on the side of the transparent cover 6, the middle part of the limiting slide groove 17 is slidably connected with a limiting rod 16, and the limiting rod 16 is fixedly connected to the top template 3.

[0032] It should be noted that the transparent cover 6 of the utility model is made of transparent plastic, the four corners of the top of the template are fixedly connected with guide columns 2, and the top template 3 is slidably connected to the outside of the guide columns 2. This design ensures the linear movement of the top template 3 during the process of opening and closing the mold, and ensures the precise alignment of the top template 3 with the bottom template 1, thereby improving the molding accuracy and quality of the product. The hydraulic cylinder 18 directly drives the top template 3 to move up and down to achieve mold closing and opening. The outside of the top template 3 is slidably connected with a transparent cover 6, which protects the operator from the harm of high-temperature metal sputtering and allows the operator to intuitively observe the working state of the mold. Through the cooperation of the limit rod 16 and the limit slide 17, the transparent cover 6 first contacts the bottom bottom template 1 to form a closed processing space, and the top template 3 can continue to complete the corresponding mold closing work.
