Description

Technical Field

[0001] This utility model relates to the field of plastic mold processing technology, and in particular to a multi-station processing equipment for plastic molds. Background Technology

[0002] Plastic molds are tools used to make shaped items. Mold processing refers to the processing of blank-making tools, and also includes die-cutting molds and mold polishing. Mold polishing increases the smoothness and makes the mold easier to demold. Mold polishing usually requires manual use of oilstones, sandpaper, wool wheels, etc. to grind the surface of the mold, which is a lot of work. Mold polishing is a very important step in the mold processing process.

[0003] A search revealed that prior art CN209648442U discloses a multi-station processing equipment for plastic molds, including an operating table. The operating table has a pre-drilled limit hole on its upper interior. The rear side of a first limit block is tightly fitted to the plastic mold body. A first gear is fixedly connected to the front side of a polishing cloth wheel, and a connecting belt is meshed with the outer side of the first gear. A second connecting rod is movably connected to the lower interior of the first connecting rod, and the first connecting rod is movably connected to the interior of a fixed rod. A bracket is fixedly connected to the upper left side of the limit plate, and a second gear is fixedly connected to the rear side of the second motor. This multi-station processing equipment for plastic molds can polish and grind multiple sets of molds simultaneously, improving work efficiency and reducing labor pressure. It can be adjusted according to the size of molds and bases of the same batch at different heights, making it widely applicable, improving the utilization rate of the polishing cloth wheel, and reducing costs.

[0004] However, when using the above-mentioned equipment, the applicant found that multiple polishing cloth wheels are driven by a synchronous belt structure. However, since the synchronous belt is elastic, there will still be errors in the transmission process, and the accurate transmission ratio cannot be guaranteed. As a result, it is difficult to keep the precision of multiple molds consistent after polishing. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station processing equipment for plastic molds, which solves the problem that the precision of multiple molds cannot be kept consistent after polishing when using existing mold polishing equipment.

[0006] To achieve the above objectives, this utility model provides a multi-station processing equipment for plastic molds, including a frame, a cam divider installed at the bottom of the frame, and an auxiliary mechanism;

[0007] The auxiliary mechanism includes a fixed plate, a mounting plate, a positioning plate, a mounting platform, an insert plate, a limiting plate, a drive motor, a polishing wheel, and a mounting device. The fixed plate is connected to the output end of the cam divider. The mounting plate is mounted on the top of the fixed plate. The positioning plate is mounted on both sides of the mounting plate and is symmetrically arranged. The mounting platform is detachably connected to the positioning plate. A mold fixing clamp can be installed on the top. The insert plate is integrally formed with the mounting platform. The limiting plate is slidably connected to the insert plate and detachably connected to the mounting plate. The drive motor is mounted on a moving plate. The polishing wheel is fixedly connected to the output shaft of the drive motor. The mounting device is located on the rear side of the frame.

[0008] The mounting device includes a bracket, a movable plate, and a guide assembly. The bracket is mounted on the rear side of the frame and has a servo cylinder mounted on its top. The movable plate is connected to the output end of the servo cylinder. The guide assembly is located on the side of the movable plate near the bracket.

[0009] The guide assembly includes a linear bearing and a guide rod. The linear bearing is mounted on the bracket and arranged symmetrically. The guide rod is integrally formed with the movable plate and slides in cooperation with the linear bearing.

[0010] The installation device further includes a cable assembly, which includes a first cable tube and a second cable tube. The first cable tube is welded to the left side of the bracket, and the second cable tube is installed on the right side of the movable plate and has an L-shaped structure.

[0011] The multi-station processing equipment for plastic molds also includes a stabilizing mechanism, which includes an insert rod and a sliding sleeve. The insert rod is integrally formed with the mounting platform and passes through the positioning plate. The sliding sleeve is detachably connected to the positioning plate and slidably connected to the insert rod.

[0012] This utility model discloses a multi-station processing equipment for plastic molds. By setting up a cam divider, a fixed plate, a mounting plate, a positioning plate, and a mounting platform, a dual-station structure for mold fixing can be formed. Thus, during mold processing, one station can perform polishing while the other station performs precision inspection, part removal, and part loading operations. In addition, the polishing wheel and the drive motor are directly connected. During polishing, the drive motor directly drives the polishing wheel to rotate for polishing. After processing multiple molds, it is beneficial to ensure the same precision dimensions, thereby solving the problem that the precision of multiple molds cannot be kept consistent after polishing in existing mold polishing equipment.
