DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-7 , the present invention provides a technical solution: a metal mold that is convenient for quick installation, including a lower mold 1. An upper mold 2 is inserted into the top of the lower mold 1. Through grooves 3 are formed on the surface of the lower mold 1. There are four groups of through grooves 3, and the four groups of through grooves 3 are equally spaced in a circumferential array with the center of the circular cross-section of the lower mold 1 as the array center. A positioning component 4 is arranged inside the lower mold 1, and a clamping component 5 is arranged on the surface of the lower mold 1.

[0028] In an embodiment of the present invention, the positioning component 4 includes a cross cam 41. The cross cam 41 is rotatably connected to the wall of the lower mold 1. The cross cam 41 is located at the center of the lower mold 1, so that the cross cam 41 will not contact the inner wall of the lower mold 1 during rotation, thereby damaging the cross cam 41 and the lower mold 1. A gear 42 is fixed to the bottom of the cross cam 41. The surface of the gear 42 meshes with one side of the rack 43 close to the gear 42. The gear 42 and the cross cam 41 are rotated by the pushing and pulling of the rack 43. An electric push rod 44 is fixed to the bottom of the rack 43. The electric push rod 44 can control the movement of the rack 43, and further control the rotation of the cross cam 41. The top of the cross cam 41 is hinged to one end of a hinge rod 45. The other end of the hinge rod 45 is hinged to the bottom of an L-shaped clamp 46. When the cross cam 41 rotates, it will drive the L-shaped clamp 46 to move through the hinge rod 45. A long slider 47 is fixed to the surface of the L-shaped clamp 46. A slide rail 48 is fixed to the inner wall of the lower mold 1. The surface of the long slider 47 is slidably connected to the inner wall of the slide rail 48, so that the L-shaped clamp 46 will move through the arranged through groove 3 during movement, and the sliding between the long slider 47 and the slide rail 48 will move, and will not contact the lower mold 1, thereby damaging the L-shaped clamp 46 and the lower mold 1. Further, the upper mold 2 and the lower mold 1 are positioned. There are four groups of hinge rods 45, L-shaped clamps 46, long sliders 47 and slide rails 48, and the four groups of hinge rods 45, L-shaped clamps 46, long sliders 47 and slide rails 48 are equally spaced in a circumferential array with the center of the circular cross-section of the cross cam 41 as the array center, so that the upper mold 2 is more accurately positioned during positioning and does not require manual positioning.

[0029] In an embodiment of the present utility model, the clamping component 5 includes a support spring 51. One end of the support spring 51 is fixed to the inner wall of the upper die 2, and a rectangular clamping block 52 is fixed to the other end of the support spring 51. The rectangular clamping block 52 can slide on the inner wall of the upper die 2 through the contraction of the support spring 51. A rectangular clamping groove 53 is formed at the end of the rectangular clamping block 52 away from the support spring 51. A sliding groove 54 is formed at the top of the lower die 1. The surface of the rectangular clamping block 52 is inserted into the inner wall of the sliding groove 54. When the upper die 2 is not positioned, the rectangular clamping block 52 abuts against the top of the lower die 1, causing the rectangular clamping block 52 to slide upward, and the support spring 51 will contract. When the positioning is completed, the support spring 51 will be released. Through the sliding of the rectangular clamping block 52 and the sliding groove 54, a fixing block 55 is fixed to the side of the lower die 1. A sliding column 56 is slidably connected inside the fixing block 55. The sliding column 56 can slide inside the fixing block 55. One end of the sliding column 56 close to the sliding groove 54 is fixed with a baffle 57. The surface of the baffle 57 is slidably connected to the inner wall of the fixing block 55. One end of the baffle 57 is fixed with an inclined block 58. When the rectangular clamping block 52 slides into the lower die 1, it will abut against the inclined block 58, causing the inclined block 58 to slide outward through the baffle 57, and at the same time driving the sliding column 56 to slide. One end of a compression spring 59 is fixed to the other end of the baffle 57, and the other end of the compression spring 59 is fixed to the inner wall of the fixing block 55. The compression spring 59 will contract during the sliding. When the rectangular clamping block 52 abuts against the sliding groove 54, the sliding column 56, the baffle 57, the inclined block 58 and the compression spring 59 will return to their original positions. At the same time, the inclined block 58 will position the upper die 2 and the lower die 1 through the rectangular clamping groove 53, making the clamping of the upper die 2 and the lower die 1 more stable. One end of the sliding column 56 away from the fixing block 55 is fixed with a pull rod 510. Pulling the pull rod 510 can release the positioning of the upper die 2. A circular clamping block 511 is fixed to the surface of the sliding column 56. The surface of the circular clamping block 511 abuts against the side of the fixing block 55 away from the lower die 1. When the pull rod 510 is released, the pull rod 510 will not enter the fixing block 55 under the action of the circular clamping block 511. Two sets of clamping components 5 are provided, which can make the clamping of the lower die 1 and the upper die 2 more stable.

[0030] Working principle: First, fix the lower die 1, and then place the upper die 2 on the top of the lower die 1. When the upper die 2 is not positioned, the rectangular clamping block 52 abuts against the top of the lower die 1, causing the rectangular clamping block 52 to slide upward, and the support spring 51 will contract. When it is necessary to position the upper die 2, start the electric push rod 44, so that the rack 43 is pushed inward, and the gear 42 will rotate, and at the same time drive the cross cam 41 to rotate. While the cross cam 41 is rotating, it will drive the articulated rod 45 to move, so that the L-shaped clamping block 46 will move inward between the long slider 47 and the slide rail 48, and at the same time position the upper die 2. After the upper die 2 is positioned, the support spring 51 will be released, and it will slide through the rectangular clamping block 52 and the chute 54. When the rectangular clamping block 52 slides inward, it will abut against the inclined block 58, causing the inclined block 58 to slide outward through the baffle 57, and at the same time drive the slide post 56 to slide, and at the same time the compression spring 59 will contract. When the rectangular clamping block 52 abuts against the chute 54, the slide post 56, the baffle 57, the inclined block 58 and the compression spring 59 will be restored. At the same time, the inclined block 58 will position the upper die 2 and the lower die 1 through the rectangular card slot 53, making the clamping of the upper die 2 and the lower die 1 more stable. When it is necessary to remove the upper die 2, it is necessary to start the electric push rod 44 to contract it outward. At the same time, the rack 43 will drive the gear 42 to rotate, so that the cross cam 41 is reset, and the L-shaped clamping block 46 will move outward, releasing the positioning of the upper die 2. Then pull the pull rod 510 to move the inclined block 58 outward, releasing the limit on the upper die 2. At this time, the removal is completed. Then release the pull rod 510, and under the action of the circular clamping block 511, the pull rod 510 will not enter the fixed block 55.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
