A groove is formed at the center of the lower mold, and the first limiting mold is placed within the groove. A square slot is formed at the lower end of the first limiting mold, and a pad is placed at the upper end of the slot. The upper end of the pad is fixed to the second spring block by screws. The upper end of the second spring block passes through the lower end of the first spring block and is placed inside the lower end of the first spring block. The upper end of the second spring block and the lower end of the first spring block are connected by a spring. The lower mold and the first limiting mold are provided with two second limiting holes at corresponding positions on both sides, and a first limiting rod is installed inside the second limiting hole. The lower mold is provided with positioning holes at the four corners of the upper end, and the positioning holes are of the same depth. The upper mold is provided with a groove at the center position, and a second limiting mold is installed in the groove. The upper mold and the second limiting mold are provided with two first limiting holes at corresponding positions on both sides, and a second limiting rod is installed inside the first limiting hole. The lower end of the upper mold is fixed with four positioning pins, and the positioning pins are at the same height as the positioning holes.

[0008] Preferably, the upper mold has handles fixed vertically on both sides of its upper end, and anti-slip sleeves are installed on the upper side of the handles.

[0010] Preferably, the second limiting mold forms a detachable structure with the upper mold through the second limiting rod and the first limiting hole, and the second limiting mold is fixed to the upper mold through the second limiting rod.

[0011] Preferably, the upper mold and the lower mold form a detachable structure through positioning holes and positioning pins. The upper mold can be kept at the same horizontal line as the lower mold by inserting the positioning pin into the positioning hole.

[0012] Preferably, the first rebound block and the second rebound block form an elastic structure through a spring, and the first rebound block, the spring and the second rebound block together constitute a rebound device.

[0013] Preferably, rubber protective sleeves are installed on the upper end of the lower mold and the lower end of the upper mold.

[0014] Preferably, the internal gap between the first limiting mold and the second limiting mold is the surface shape of the limiting object, and when the pressure at the upper end of the first rebound block decreases, the upper surface of the first rebound block should be higher than the lower end of the internal gap of the first limiting mold.

[0015] The working principle and beneficial effects of this utility model are as follows: A groove is provided at the center of the lower mold, and a first limiting mold is placed in the groove. A square groove is provided at the lower end of the first limiting mold, and a pad is placed at the upper end of the groove. A second spring block is fixed to the upper end of the pad by screws. The upper end of the second spring block passes through the lower end of the first spring block and is placed inside the lower end of the first spring block. The upper end of the second spring block and the lower end of the first spring block are connected by a spring. Two second limiting holes are provided at corresponding positions on both sides of the lower mold and the first limiting mold. A first limiting rod is installed inside the hole. Positioning holes of the same depth are formed at the four corners of the upper end of the lower mold. A groove is formed at the center of the upper mold, and a second limiting mold is placed within the groove. Two first limiting holes are formed on corresponding positions on both sides of the upper mold and the second limiting mold, and second limiting rods are installed inside the first limiting holes. Four positioning pins are fixed to the lower end of the upper mold, and the positioning pins are at the same height as the positioning holes.

The upper end of the lower mold is connected to the upper mold. A rubber protective sleeve is installed on the lower surface. The internal gap of the first and second limiting molds is the surface shape of the limiting object. When the pressure on the upper end of the first rebound block decreases, the upper surface of the first rebound block should be higher than the lower end of the internal gap of the first limiting mold. The upper mold and the second limiting mold can be separated from the lower mold and the first limiting mold by the handle. The rubber protective sleeve between the two can prevent friction between the molds and reduce the wear of the device. When the mold is closed, the positioning hole and positioning pin can align the upper mold and the lower mold for easy operation. The limiting mold is fixed to the mold by the limiting rod. By removing the limiting rod and replacing the limiting mold with a different shape, the device can be used in different fields. This solves the problem that the device can only store specific molds, and the storage structure is fixed, so the device can only be used in a single field. A rebound device is placed at the lower end of the first limiting mold. When the device opens the mold, the pressure on the rebound device decreases, and the spring will push the first rebound block to open the mold placed above, making it easier to pick up the mold. This solves the problem that the device is difficult to pick up the mold and is extremely inconvenient to use. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4As shown, this example proposes a limiting mold with holes, including a lower mold 1, a first limiting mold 3, an upper mold 6, a second limiting mold 8, a first spring block 13, and a second spring block 14. A groove is formed at the center of the lower mold 1, and the first limiting mold 3 is placed within the groove. Two second limiting holes 12 are formed at corresponding positions on both sides of the lower mold 1 and the first limiting mold 3, and a first limiting rod 2 is placed inside the second limiting holes 12. The first limiting mold 3 forms a detachable structure with the lower mold 1 through the second limiting holes 12 and the first limiting rod 2. The first limiting mold 3 can be fixed to the lower mold 1 by the first limiting rod 2. A square groove is formed at the lower end of the first limiting mold 3, and a pad 16 is placed at the upper end of the groove. The upper end of the pad 16 is fixed by screws. A second rebound block 14 is provided, with its upper end penetrating the lower end of the first rebound block 13 and placed inside the lower end of the first rebound block 13. The upper end of the second rebound block 14 is connected to the lower end of the first rebound block 13 via a spring 15. The first rebound block 13 and the second rebound block 14 together form an elastic structure. The first rebound block 13, the spring 15, and the second rebound block 14 together constitute a rebound device. When the pressure on the upper end of the first rebound block 13 decreases, the upper surface of the first rebound block 13 should be higher than the lower end of the internal gap of the first limiting mold 3. Handles 9 are vertically fixed on both sides of the upper end of the upper mold 6, and anti-slip sleeves 10 are installed on the upper side of the handles 9. A groove is opened at the center of the upper mold 6, and a second limiting mold 8 is placed in the groove. The upper mold 6 and the second limiting mold 8 are connected. Two first limiting holes 11 are provided at corresponding positions on both sides, and a second limiting rod 7 is installed inside the first limiting hole 11. The second limiting mold 8 forms a detachable structure with the upper mold 6 through the second limiting rod 7 and the first limiting hole 11. The second limiting mold 8 is fixed to the upper mold 6 through the second limiting rod 7. The lower mold 1 has positioning holes 4 at the four corners of its upper end, and the positioning holes 4 are of the same depth. Four positioning pins 5 are fixed at the lower end of the upper mold 6, and the positioning pins 5 are at the same height as the positioning holes 4. The upper mold 6 forms a detachable structure with the lower mold 1 through the positioning holes 4 and the positioning pins 5. The upper mold 6 can be kept at the same horizontal line as the lower mold 1 by inserting the positioning pins 5 into the positioning holes 4. Rubber protective sleeves are installed on the upper end of the lower mold 1 and the lower end of the upper mold 6. The internal gaps of mold 3 and the second limiting mold 8 are shaped to the surface of the limiting object. The upper mold 6 and the second limiting mold 8 can be separated from the lower mold 1 and the first limiting mold 2 via handle 9. Rubber protective sleeves between the two molds prevent friction and reduce wear. When the molds are closed, positioning holes 4 and positioning pins 5 align the upper mold 6 and the lower mold 1 for easy operation. The limiting molds are fixed to the molds by limiting rods. Removing the limiting rods and replacing them with different shaped limiting molds allows the device to be used in different fields, solving the problem that the device can only store specific molds, has a fixed structure, and can only be used in a single field. A springback device is placed at the lower end of the first limiting mold 3; when the device opens the mold, the pressure on the springback device decreases.The spring pushes up the first rebound block, opening the mold placed above, making it easier to remove. This solves the problem of the device being difficult to use and extremely inconvenient.
