[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 to 6As shown, a fixing structure for a die-casting mold comprises: a fixing plate 1, four fixing rods 2, four containing rings 3 and four positioning blocks 4, wherein the fixing rods 2 and the positioning blocks 4 are fixed on one side of the fixing plate 1, and the other side of the fixing plate 1 is connected to the die-casting machine, a limiting ring 13 is fixedly arranged on the side of the positioning block 4 away from the fixing plate 1, a sleeve rod 5 is fixedly arranged on one side of the limiting ring 13, a second cone 9 is movably sleeved on the sleeve rod 5, a first cone 8 is fixedly arranged on one side of the sleeve rod 5, a first spring 10 is sleeved on the sleeve rod 5, one end of the first spring 10 is fixed to the first cone 8, and the other end of the first spring 10 is fixed to the second cone 9, and the containing ring 3 is arranged At the corresponding position of the first cone 8, two limit rods 11 arranged opposite to each other are arranged inside the accommodating ring 3, a through hole for accommodating the limit rod 11 is opened inside the accommodating ring 3, a guide block 7 is arranged on one side of the limit rod 11, a second spring 12 is sleeved on the limit rod 11, one end of the second spring 12 is fixedly connected to the guide block 7, the other end of the second spring 12 is connected to the inner wall of the accommodating ring 3, a limit block 18 is arranged on the other end of the limit rod 11 away from the guide block 7, a through groove for accommodating the limit rod 11 is opened inside the accommodating ring 3, and a hole with the same diameter value as the limit rod 11 is opened at the through groove located on the outer wall of the accommodating ring 3, and the diameter value of the second spring 12 is The guide block 7 is larger than the above-mentioned hole position, and a threaded rod 6 is fixedly connected to the other side of the accommodating ring 3. The guide block 7 moves toward the first cone 8 when in use, and moves to both sides after being guided by the slope. After passing through the first cone 8, the guide block 7 is clamped into the gap position between the first cone 8 and the second cone 9 under the action of the second spring 12. When the mold needs to be taken out, it is only necessary to move the guide block 7 toward the second cone 9. At this time, the guide block 7 is guided in the opposite direction through the second cone 9. The guide block 7 will press the second cone 9 to approach the first cone 8. After the two overlap, due to the fixed setting of the first cone 8, the guide block 7 will pass through the slope of the second cone 9 and directly detach from the first cone. 8 and the second cone 9, so that the two are separated, the structure can be more convenient and quick to disassemble and assemble, thereby better improving the practicality of the device. At the same time, when the mold is installed, the operating lever 17 rotates and moves backward in the spiral groove 16, and the lever 17 will drive the extrusion block 15 to compress the expansion sleeve 14, causing the expansion sleeve 14 to expand and deform, thereby further fixing the mold. The cooperation between the lever 17, the extrusion block 15 and the expansion sleeve 14 allows the structure to further fix the die-casting mold after it is installed, making the die-casting mold more stable during operation and the production process safer, further improving the practicality of the structure.

[0028] Further, such as Figure 4As shown, an expansion sleeve 14 is provided on one side of the fixed rod 2, and an extrusion block 15 is provided on one side of the expansion sleeve 14. A spiral groove 16 is provided on the side wall of the fixed rod 2 away from the extrusion block 15, and a lever 17 is provided inside the spiral groove 16. The structure drives the extrusion block 15 by controlling the lever 17, thereby pressing the expansion sleeve 14 to expand, so as to produce the effect of fixing the mold, thereby improving the practicability and safety of the device.

[0029] Further, such as Figure 2 As shown, the threaded pattern arranged on the threaded rod 6 is consistent with the thread of the positioning hole reserved on the die-casting mold. The consistent pattern can better install the positioning and limiting components on the die-casting mold, thereby eliminating the need to make major changes to the die-casting mold itself, thereby improving the scope of application of the structure and improving the practicability of the structure.

[0030] Further, such as Figure 4 As shown, the extrusion block 15 is located inside the fixed rod 2 and is a threaded structure. The lever 17 passes through the inner wall of the fixed rod 2 and is fixedly connected to the extrusion block 15 inside the fixed rod 2. The fixed connection relationship between the lever 17 and the extrusion block 15 can more easily trigger the fixing effect of the structure, making the structure easier to use and improving the practicality of the structure.

[0031] Further, such as Figure 2 As shown, the first cone 8 and the second cone 9 are conical structures with one end larger than the other end. The first cone 8 is fixedly arranged on the sleeve rod 5, and the second cone 9 is movably sleeved on the sleeve rod 5. The large ends of the first cone 8 and the second cone 9 are arranged corresponding to each other. The special shape of the cone can achieve the effect of quick disassembly, and the disassembly can be achieved with a simpler structure, thereby improving the practical value of the structure.

[0032] Further, such as Figure 3 As shown, the lower side of the guide block 7 is sloped, and the slope of the guide block 7 is consistent with the slope of the upper part of the first cone 8. The consistent slope structure can make the two better cooperate with each other, thereby achieving the effect of quick disassembly.

[0033] Further, such as Figure 2 As shown, the diameter of the hole opened below the accommodating ring 3 is consistent with the maximum diameter of the first cone 8 below. By setting consistent sizes, the structure can be more tightly matched during use, and the use effect of the structure itself will not be affected by problems such as position or size.

[0034] Further, such as Figure 6As shown, there are also two movable blocks 19, each of which has two arc grooves, and the arc groove is clamped between the first cone 8 and the second cone 9. The movable block 19 is an external accessory, which is used in conjunction with the structural body to ensure better and more stable operation of the structure.

[0035] Working principle:

[0036] During use, the die-casting mold is first moved to the inside of the structure. At this time, the threaded rod 6 is installed into the positioning hole of the die-casting mold, and then the first cone 8 is inserted into the receiving ring 3 at the corresponding position. At this time, the movable block 19 is placed between the first cone 8 and the second cone 9 to ensure that the guide block 7 does not reach the bottom of the second cone 9. At the same time, the fixed rod 2 is inserted into the fixed hole position of the mold, and the lever 17 is moved to make it reach the bottom of the spiral groove 16, driving the extrusion block 15 to move into the fixed rod 2, thereby pressing the expansion sleeve 14 to make It expands and fixes the die-casting mold. At this time, die-casting work can be carried out. When the die-casting work requires disassembly of the mold, the movable clamping block 19 is taken out from the inside of the structure, and then the lever 17 is operated to make it reach the top of the spiral through groove 16, and the pressure of the extrusion block 15 on the expansion sleeve 14 is released, and then the mold is moved closer to the inside of the structure. Under the cooperation of the inclined surface of the guide block 7 and the second spring 12, the guide block 7 will move to both sides, so that the guide block 7 reaches the bottom of the second cone 9. At this time, force is applied in the opposite direction to directly take out the die-casting mold.
