Description

Technical Field

[0001] This utility model belongs to the field of positioning equipment technology, and in particular to a positioning mechanism for automotive plastic parts molds. Background Technology

[0002] Automotive plastic parts are product parts made of plastic used in automobiles. These parts are widely used in automobiles. During the production of automotive plastic parts, molds are typically used for processing. Existing mold positioning mechanisms, in order to prevent gaps between two mold parts, use positioning pillars and guide seats to achieve positioning during processing, increasing the practicality of the device to a certain extent. However, while this increases practicality to some extent, when unloading automotive plastic parts from the mold, manual assistance with wearing gloves is required, which can easily lead to burns for workers, resulting in a low safety factor for the device.

[0003] A search revealed a Chinese patent document (authorization announcement number CN220297615U), which discloses a positioning mechanism for automotive plastic parts molds, relating to the field of automotive plastic parts technology. The mechanism includes two molds: a first mold and a second mold. A guiding component is provided at the connection between the first and second molds. A positioning component is mounted on the guiding component. The guiding component includes a guide seat fixedly mounted on the second mold and a mating block fixedly mounted on the first mold. Guide rods are symmetrically fixedly connected to the guide seat, and positioning grooves are provided on the guide rods. A positioning post is fixedly connected to the center of the guide seat. While this patent increases the practicality of the device to some extent, manually unloading automotive plastic parts from the mold requires workers to wear gloves, which can easily lead to burns and reduces the safety factor of the device.

A positioning component is mounted on the side of the mounting platform. A fixed end of a first linear motor is mounted on the side of the mounting platform, and a limit plate is fixedly connected to the driving end of the first linear motor. A fixed end of an electric push rod is connected to the vertical side of the limit plate, and a mounting box is connected to the driving end of the electric push rod through the limit plate. A first lead screw is rotatably connected to the inner side of the mounting box, and a drive motor that provides adjustment power to the first lead screw is mounted on the side of the mounting box. Two symmetrical movable blocks are threaded to the outer periphery of the first lead screw, and a movable rod is hinged to the bottom end of each movable block via a hinge. A linkage plate is hinged to the end of the movable rod away from the movable block. A fixed box is fixedly connected to the bottom end of the linkage plate, and a second lead screw is rotatably connected to the inner side of the fixed box. A stepper motor that provides adjustment power to the second lead screw is mounted on the side of the fixed box, and two fixed plates are threaded to the outer periphery of the second lead screw.

[0006] Preferably, the top of the mounting platform is provided with a cooling groove, and a water-cooled radiator communicating with the cooling groove is installed on the side of the mounting platform, and multiple fans are embedded in the side of the mounting platform.

[0007] Preferably, the side of the mounting platform is equipped with the fixed end of the second linear motor, and the drive end of the second linear motor is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a wire frame.

[0008] Preferably, the positioning assembly includes a mounting plate mounted on the side of the mounting platform, a fixed end of the mounting plate with a hydraulic rod mounted on its top, and an upper mold mounted on the drive end of the hydraulic rod.

[0009] Preferably, a screw is rotatably connected to the inner side of the mounting platform, and one end of the screw passes through the mounting platform and is connected to an adjusting wheel.

[0010] Preferably, the screw has two fixed symmetrical linkage blocks connected to its outer circumference by threads, and the top of the linkage block is fixedly connected to a positioning plate through a limiting groove provided on the top of the mounting platform.

[0011] Preferably, a detachable lower mold is installed between the two positioning plates.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This automotive plastic parts mold positioning mechanism, thanks to the design of the electric push rod and positioning components, allows the electric push rod to move the mounting box horizontally after the automotive plastic parts are processed, positioning it between the lower and upper molds. The drive motor then adjusts two movable blocks around the first lead screw, which in turn adjusts the linkage plate at the bottom of the movable rod. Simultaneously, a stepper motor moves the fixing plate around the second lead screw in opposite directions, fixing the molded automotive plastic mold. Once fixed, the drive motor adjusts the height, working in conjunction with the adjustment of the first linear motor to achieve automatic unloading. Compared to existing devices that rely on manual unloading, this automatic unloading effectively prevents burns to workers, significantly improving safety. Furthermore, the positioning components allow for quick positioning of the lower mold, making mold replacement more convenient.

[0014] This automotive plastic parts mold positioning mechanism can automatically unload materials, effectively preventing workers from being burned and making the device highly safe. Attached Figure Description

[0029] Working principle

[0030] The positioning mechanism for automotive plastic parts molds involves the following steps: After the mold is formed, the electric push rod 4 drives the mounting box 6 to move horizontally between the lower mold 34 and the upper mold 32. The drive motor 7 then adjusts the two movable blocks 14 around the first lead screw 13. The adjustment of the movable blocks 14 adjusts the linkage plate 16 at the bottom of the movable rod 15. Simultaneously, the stepper motor 17 moves the fixing plate 18 around the second lead screw 19 towards each other, fixing the formed automotive plastic mold. After fixing, the drive motor 7 is activated for high-speed... After adjusting the temperature, remove the finished product from the lower mold 34, start the first linear motor 2 to move the finished product horizontally (to the top of the cooling tank), and after adjustment, start the stepper motor 17 to move the two fixing plates 18 in the opposite direction (to release the fixing of the finished product). The finished product falls into the mesh frame 12 (the mesh frame 12 is below the liquid level), so that the finished product can enter the cooling tank for cooling. After cooling, start the second linear motor 11 to raise the mesh frame (to the installation position of the fan 9), and turn on the fan 9 for drying, which effectively prevents the phenomenon of artificial burns.
