Figure 2 is a schematic structural diagram of a transmission assembly of the first embodiment of the utility model, Figure 3 It is a structural schematic diagram of the fixing component of the first embodiment of the utility model. The utility model provides a mold positioning device, including a positioning platform 101, a transmission component and a fixing component. The transmission component includes a No. 1 screw rod 102, a No. 2 screw rod 103, a support seat 104, a transmission bevel gear 105, a double-sided bevel gear 106, a transmission shaft 107 and a motor 108. The fixing component includes a moving seat 109, a guide bar 110, a support plate 111, a buffer spring 112 and a buffer plate 113. The above-mentioned scheme solves the problem that the automobile mold positioning device can only position the two sides of the mold when in use, and cannot achieve a good centering effect on the mold, resulting in the mold being easily offset during processing. It can be understood that the above-mentioned scheme can be used in the scenario of mold positioning, and can also be used to solve different types of mold positioning problems.

[0021] According to this specific embodiment, the first screw rod 102 is rotatably connected to the positioning platform 101 and is located inside the positioning platform 101. The second screw rod 103 is rotatably connected to the positioning platform 101 and is located inside the positioning platform 101. The support seat 104 is rotatably connected to the positioning platform 101 and is located between the first screw rod 102 and the second screw rod 103. There are two transmission bevel gears 105, and the two transmission bevel gears 105 are fixedly connected to the first screw rod 102 and the second screw rod 103, respectively, and are located on the outside of the first screw rod 102 and the second screw rod 103, respectively. The double-sided bevel gear 106 is rotatably connected to the support seat 104 and is located The fixed component is connected to the positioning platform 101 between the two transmission bevel gears 105. The positioning platform 101 and the support seat 104 provide support for the equipment. The transmission shaft 107 and the first screw rod 102 are driven to rotate through the rotation of the motor 108. The power is transmitted to the second screw rod 103 through the cooperation of the two transmission bevel gears 105 and the double-sided bevel gear 106. Both the first screw rod 102 and the second screw rod 103 are bidirectional screw rods. Through the rotation of the first screw rod 102 and the second screw rod 103, the fixed component is driven to move toward the center of the positioning platform 101 respectively, so as to achieve the purpose of positioning the mold and make it easier for the mold to achieve the centering effect.

[0022] Among them, the transmission shaft 107 is fixedly connected to the No. 1 screw rod 102 and passes through the positioning platform 101. The motor 108 is connected to the transmission shaft 107 and is located on the outside of the positioning platform 101. The motor 108 provides power for the transmission assembly, and the transmission shaft 107 transmits the power provided by the motor 108 to the No. 1 screw rod 102.

The buffer springs 112 provide elastic force for the buffer plates 113. When the movable seat 109 moves toward the center, the buffer plates 113 contact the mold. The elastic force provided by the buffer springs 112 reduces the impact force of the buffer plates 113 on the mold, reduces damage to the mold, and extends the service life of the equipment.

[0025] A mold positioning device according to the present embodiment is used, wherein the positioning platform 101 and the support seat 104 provide support for the equipment, and the rotation of the motor 108 drives the transmission shaft 107 and the first screw rod 102 to rotate, and the four transmission bevel gears 105 and the double-sided bevel gears 106 cooperate with each other to transmit power to the second screw rod 103. The first screw rod 102 and the second screw rod 103 are both bidirectional screw rods, and the rotation of the first screw rod 102 and the second screw rod 103 respectively drives the fixing assembly to move toward the center of the positioning platform 101, so as to achieve the purpose of positioning the mold and make it easier for the mold to achieve a centering effect, thereby solving the problem that the automobile mold positioning device can only position the two sides of the mold when in use, and cannot achieve a good centering effect on the mold, resulting in the mold being easily offset during processing.
