[0002] With the continuous development of the social economy and the constant progress of science and technology, my country's manufacturing industry has entered a stage of high-quality development. Especially in the precision manufacturing fields such as auto parts, electronic components, and medical devices, more stringent requirements have been placed on the precision and efficiency of mold processing. In the precision mold processing flow, positioning and clamping fixtures, as core supporting equipment, directly determine the dimensional accuracy, surface quality, and production cycle of the finished mold, and are a key link to ensure the stable implementation of precision manufacturing processes.

[0003] Currently, when using precision mold positioning and clamping fixtures for clamping and positioning, operators need to accurately align the mold with the positioning reference and then fix it through the positioning and clamping device. During this process, the mold is prone to collision with the fixture parts, and the position needs to be adjusted repeatedly. This not only increases the difficulty of operation, but also greatly reduces the speed of mold positioning and clamping, making it difficult to meet the high-efficiency production needs of the precision manufacturing field.

The clamping component includes two connecting rods 21. The outer walls of the two connecting rods 21 pass through opposite sides of the two fixed seats 12 respectively, and a spring 22 is sleeved on one end of the outer wall of each connecting rod 21. A reference seat 23 is fixed on the opposite end of each of the two connecting rods 21. Two rod seats 24 are fixed on the opposite side of each of the two reference seats 23. Two hydraulic rods 25 are provided on the inner walls of the four rod seats 24. A connecting seat 26 is fixed on the telescopic end of each of the two hydraulic rods 25. A clamping plate 27 is fixed on the opposite side of each of the two connecting seats 26. The connecting rod 21 is slidably engaged with the fixed seat 12. The tops of the two reference seats 23 are set at an angle on one side adjacent to each other. The rod seat 24 is fixedly connected to the hydraulic rod 25. The hydraulic rod 25 is connected and supported by the rod seat 24, thereby improving the overall stability of the hydraulic rod 25. The hydraulic rod 25 adopts the DYTP1000-500 model, which is used to provide the driving force required for the movement and clamping of the clamping plate 27. Rubber pads are glued to the opposite side of the two clamping plates 27.

[0019] The clamping component also includes two limiting blocks 28, with the opposite sides of the two limiting blocks 28 respectively fixedly disposed at opposite ends of the two connecting rods 21; The limiting block 28 is used to limit the movement of the connecting rod 21.

[0020] The opposite ends of the two springs 22 are fixedly connected to the opposite sides of the two reference seats 23, and the opposite ends of the two springs 22 are fixedly connected to the opposite sides of the two fixed seats 12.

[0021] The bottom ends of the two clamping plates 27 are slidably provided with movable seats 210, and the opposite sides of the two movable seats 210 are slidably provided with crossbars 211, and the two ends of the crossbars 211 are respectively fixedly connected to the two sides of the fixed groove 111. The movable seat 210, in conjunction with the crossbar 211, is used to assist in the movement and guidance of the clamping plate 27. The top of the outer wall of the crossbar 211 is lower than the top of the fixed groove 111.

[0022] The bottom ends of the two reference seats 23 are each fixedly provided with a first slider 29, and the outer walls of the two first sliders 29 are slidably connected to the two sides of the top of the clamping table 11 respectively. The first slider 29 is used to guide the auxiliary movement of the reference base 23.

[0024] Working principle: The precision mold is placed between two reference seats 23 and moved downwards. The mold moves downwards along the inclined surfaces of the two reference seats 23, causing the two reference seats 23 to move in opposite directions. The movement of the reference seats 23 compresses the spring 22 until the mold contacts the top of the clamping table 11. At this time, under the elastic action of the spring 22, the two reference seats 23 are pressed tightly against the two sides of the mold. Then, the hydraulic rod 25 is opened. The hydraulic rod 25 works through the two connecting seats 26 to drive the two clamping plates 27 to move towards each other until the clamping plates 27 are respectively in contact with the other two sides of the mold. In this way, the mold can be quickly positioned and clamped without repeated adjustments. This not only reduces the difficulty of operation, but also greatly improves the speed of mold positioning and clamping, thus adapting to the high-efficiency production needs of the precision manufacturing field.

[0025] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment. Several connecting grooves 31 are provided on the opposite side of the two reference seats 23, and rollers 32 are rotatably provided on the inner wall of the several connecting grooves 31. Several connecting slots are equidistantly designed.

[0026] The distance between two opposing rollers 32 is matched with the distance between two opposing connecting grooves 31.

[0027] Working principle: After the mold is positioned by the two reference seats 23, when the mold is clamped and moved by the clamping plate 27, the sliding friction between the mold and the reference seat 23 is changed to rolling friction under the action of the roller 32, thereby reducing the wear on the mold.
