Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a polishing device for injection molds. Background Technology

[0002] Injection molds play a crucial role in the production of plastic products, and their surface quality directly affects the appearance and performance of these products. Polishing is an important process in injection mold manufacturing, designed to remove surface defects and scratches, improve surface smoothness, and thus ensure the high precision and quality of the plastic products.

[0003] Traditional injection mold polishing methods have many limitations. Some manual polishing methods rely on workers' experience and skills, which are labor-intensive and difficult to guarantee consistent polishing quality. They are also inefficient and cannot meet the needs of large-scale production. Existing polishing equipment has limited functions and low automation. During the polishing process, parameters cannot be flexibly adjusted to adapt to the complex shapes and material requirements of different molds. Utility Model Content

[0004] This invention proposes a polishing device for injection molds that automatically adjusts the height according to changes in the surface height of the injection mold, enabling more flexible and efficient polishing of injection molds.

[0005] A polishing device for injection molds includes a base frame, a mounting frame on the top of the base frame, a slide rail inside the mounting frame, a slider slidably mounted on the slide rail, a support plate fixedly connected to the slider, a driving mechanism fixedly connected to the support plate, a connecting plate fixedly connected to the end of the driving mechanism away from the support plate, a polishing mechanism driven by the driving mechanism, the polishing mechanism being fixed to the connecting plate, and a moving mechanism on the mounting frame.

[0006] The moving mechanism includes a lead screw motor fixed on the mounting frame, the lead screw motor driving a threaded rod, an L-shaped connecting block threaded onto the threaded rod, the L-shaped connecting block being fixedly connected to the support plate, and a sensor for detecting the position of the injection mold located below the threaded rod in the mounting frame.

[0007] With the above structure, the sensor can detect changes in the height of the injection mold surface. The moving mechanism moves the position of the support plate according to the changes in the height of the injection mold surface, which in turn drives the position of the polishing mechanism to move according to the changes in the height of the injection mold surface. The injection mold polishing device can automatically adjust the height according to the changes in the height of the injection mold surface to achieve a more flexible and efficient polishing effect.

[0008] Preferably, the driving mechanism includes a drive motor fixed on the support plate, one end of the drive motor away from the support plate is fixedly connected to the connecting plate, and the output end of the drive motor is driven to be connected to a main synchronous pulley;

[0009] The polishing mechanism includes a reducer fixed on the connecting plate. The input end of the reducer is provided with a driven synchronous pulley. The main synchronous pulley and the driven synchronous pulley are covered with a synchronous belt. The output end of the reducer is driven and connected to a polishing wheel.

[0010] To provide space for the injection mold, two bearings are installed on the base frame, and rollers are fixedly installed on the inner circumferential surface of each bearing. The two rollers are located directly below the polishing wheel.

[0011] To ensure a more stable connection between the support plate and the connecting plate, a connecting rod is fixedly connected between the support plate and the connecting plate, and the connecting rod is located between the drive motor and the reducer.

[0012] In order to detect changes in the surface height of the injection mold without contacting the injection mold, the sensor is a non-contact distance sensor.

[0013] Preferably, the mounting frame is provided with a mounting groove, and the slide rail is fixedly installed in the mounting groove.

[0014] Preferably, a counting disk is provided on the side of the main synchronous pulley away from the drive motor, and a protective cover is provided on the counting disk, the secondary synchronous pulley and the synchronous belt, and a counter sensor is provided on the protective cover above the counting disk.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] This invention includes a moving mechanism and a sensor. The sensor can detect changes in the height of the injection mold surface. The moving mechanism moves the position of the support plate according to the changes in the height of the injection mold surface, which in turn drives the position of the polishing mechanism to move according to the changes in the height of the injection mold surface. The injection mold polishing device provided by this invention can automatically adjust the height according to the changes in the height of the injection mold surface to achieve a more flexible and efficient polishing effect.

They only represent relative positional relationships and do not represent absolute positional relationships.

[0025] like Figure 1-5 As shown, a polishing device for injection molds includes a base frame 1, a mounting frame 2 on the top of the base frame 1, a slide rail 22 inside the mounting frame 2, a slider 71 slidably mounted on the slide rail 22, a support plate 7 fixedly connected to the slider 71, a drive mechanism 3 fixedly connected to the support plate 7, a connecting plate 8 fixedly connected to the end of the drive mechanism 3 away from the support plate 7, a polishing mechanism 4 driven by the drive mechanism 3, the polishing mechanism 4 fixed to the connecting plate 8, and a moving mechanism 5 on the mounting frame 2. The moving mechanism 5 includes a lead screw motor 51 fixed to the mounting frame 2, a threaded rod 52 driven by the lead screw motor 51, an L-shaped connecting block 53 threadedly connected to the threaded rod 52, the L-shaped connecting block 53 fixedly connected to the support plate 7, and a sensor 6 for detecting the position of the injection mold located below the threaded rod 52 on the mounting frame 2. Specifically, the sensor 6 is a non-contact distance sensor, which can detect changes in the surface height of the injection mold without contacting the injection mold.

[0026] Sensor 6 can detect changes in the height of the injection mold surface. The moving mechanism 5 moves the position of the support plate 7 according to the changes in the height of the injection mold surface, which in turn drives the position of the polishing mechanism 4 to move according to the changes in the height of the injection mold surface. The injection mold polishing device can automatically adjust the height according to the changes in the height of the injection mold surface to achieve a more flexible and efficient polishing effect.

[0027] The drive mechanism 3 includes a drive motor 31 fixed on the support plate 7. One end of the drive motor 31, away from the support plate 7, is fixedly connected to a connecting plate 8.

The output end of the reducer 42 is driven and connected to a polishing wheel 43. A protective cover 9 is provided around the main synchronous pulley 32, the driven synchronous pulley 41, and the synchronous belt 33. When the drive motor 31 starts, it drives the main synchronous pulley 32 to rotate. This rotation is then transmitted through the synchronous belt 33, causing the driven synchronous pulley 41 to rotate. The rotation of the driven synchronous pulley 41 is then reduced in speed by the reducer 42, driving the polishing wheel 43 to rotate.

[0028] Two bearings 11 are installed on the base frame 1. Rollers 12 are fixedly installed on the inner circumference of the bearings 11. The two rollers 12 are located directly below the polishing wheel 43. The space between the two rollers 12 is used to place the injection mold.

[0029] A connecting rod is fixedly connected between the support plate 7 and the connecting plate 8. The connecting rod is located between the drive motor 31 and the reducer 42, and the connecting rod makes the connection between the support plate 7 and the connecting plate 8 more stable.

[0030] The mounting frame 2 is provided with a mounting groove 21, and a slide rail 22 is fixedly installed in the mounting groove 21, so that the drive mechanism 3 and the polishing mechanism 4 can move along the direction of the slide rail.

[0031] A counting disk 34 is provided on the side of the main synchronous pulley 32 away from the drive motor 31. A protective cover 9 is provided on the counting disk 34, the synchronous pulley 41 and the synchronous belt 33. A counter sensor 81 fixed on the connecting plate 8 is provided on the protective cover 9 above the counting disk 34 to count the number of polishing times and to polish the surface of the injection mold more accurately.
