Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a polishing equipment for plastic mold steel. Background Technology

[0002] In the plastic mold manufacturing process, the surface quality of mold steel has a significant impact on the molding quality, demolding performance, and service life of plastic products. A good surface polishing effect of mold steel can reduce the friction between plastic and mold surface, making plastic products easier to demold, while reducing surface defects and improving the appearance quality of plastic products.

[0003] The existing patent document CN210879144U discloses a polishing equipment for plastic mold steel. This utility model uses a transmission device to transport the plastic mold steel sheet to be polished and an auxiliary fixing device to fix the plastic mold steel sheet. At the same time, it can move the polishing wheel to a designated position to polish the plastic mold steel sheet. During the operation of this device, the scraper can scrape off the dust and debris on the conveyor belt of the transmission device and let it fall into the recycling tank.

[0004] However, existing plastic mold steel polishing equipment is not convenient for simultaneous double-sided polishing of the processed plastic mold steel. Most traditional equipment is only equipped with a single polishing mechanism, which can only polish one side of the mold steel sequentially. To complete double-sided polishing, a second clamping and positioning operation is required, which is not only time-consuming and labor-intensive, but also prone to positioning errors during the second clamping process, affecting the polishing accuracy and the dimensional consistency of the mold steel. This greatly limits the processing efficiency and quality stability of double-sided polishing of plastic mold steel, making it difficult to meet the urgent needs of modern manufacturing industry for high-precision and high-efficiency mold processing. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a polishing equipment for plastic mold steel, so as to solve the problem mentioned in the background art that the existing polishing equipment for plastic mold steel is not convenient for simultaneous polishing of both sides of the processed plastic mold steel.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a plastic mold steel polishing equipment, including a workbench, a support frame fixedly installed above the workbench, an installation groove fixedly installed on one side of the upper surface of the support frame, an adjusting motor fixedly installed on one side inside the installation groove, and a double-sided threaded rod fixedly connected to the transmission end of the adjusting motor.

[0009] The end of the double-sided threaded rod away from the adjusting motor is connected to the mounting groove via a bearing. An internal thread adjusting block is threadedly connected to the outer surface of the double-sided threaded rod. An adjusting plate is fixedly connected to one side of the internal thread adjusting block. A polishing motor is installed on the outer side of the two sets of adjusting plates. A polishing wheel is fixedly connected to the transmission end of the polishing motor through the adjusting plate.

[0010] Furthermore, a support mesh plate is fixedly installed on the upper surface of the workbench, a fixed seat is fixedly installed in the middle of the upper surface of the support mesh plate, and a connecting frame is fixedly connected to one side of the fixed seat.

[0011] Furthermore, an electric push rod is installed on the upper surface of the connecting frame, and a push rod is fixedly connected to the transmission end of the bottom of the electric push rod through the connecting frame.

[0012] Furthermore, a pressure block is fixedly connected to the end of the push rod away from the electric push rod, and the pressure block corresponds to the fixed base.

[0013] Furthermore, a support block is fixedly connected to the side of the adjusting plate away from the internal thread adjusting block, and a support groove is fixedly provided on the side of the upper surface of the support frame away from the mounting groove, and the support block is slidably connected to the support groove.

[0014] Furthermore, the workbench is equipped with a water storage chamber inside, and a negative pressure fan is fixedly installed on one side of the workbench.

[0015] Furthermore, a filter shell is provided on one side of the water storage chamber, the filter shell is corresponding to the negative pressure fan, and a sealing plate is provided on the outer surface of the workbench.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This plastic mold steel polishing equipment uses an adjustable motor to drive a double-sided threaded rod to rotate. Utilizing the reverse thread characteristics at both ends, the internal thread adjustment blocks on both sides move synchronously towards or away from each other, thereby driving the adjustment plate, polishing motor, and polishing wheels to adjust their spacing. This design can polish both sides of the plastic mold steel simultaneously, doubling the processing efficiency compared to the traditional single-end polishing method. Furthermore, the position of the double polishing wheels can be precisely adjusted according to the width of the mold steel, ensuring that the polishing wheels are in close contact with the surface of the mold steel, achieving efficient and uniform polishing operations, and effectively avoiding the problem of mold steel deformation caused by uneven force during single-sided polishing.

[0018] 2. This plastic mold steel polishing equipment uses an electric push rod on the connecting frame to drive the push rod and pressure block downwards. Together with the fixed base, they firmly clamp the plastic mold steel onto the support mesh plate. The electric push rod can precisely control the downward pressure of the pressure block, ensuring that the mold steel does not shift during polishing and preventing damage to the mold steel surface due to excessive pressure. For mold steel of different thicknesses and shapes, simply adjusting the extension length of the electric push rod achieves fast and stable clamping. Compared to traditional manual clamping methods, clamping efficiency is significantly improved, while providing a stable foundation for high-quality polishing.

[0019] 3. This plastic mold steel polishing equipment utilizes a water storage chamber, filter shell, and negative pressure fan working in tandem within the worktable. During polishing, the negative pressure fan generates suction, drawing the polishing dust into the water storage chamber. As the dust passes through the filter shell, the intercepted dust particles are adsorbed and settled by the water in the storage chamber under gravity, achieving efficient dust removal. The sealing plate prevents dust leakage, ensuring a clean working environment and effectively reducing the health hazards of dust to operators. It also prevents dust accumulation from affecting equipment operation and extends equipment lifespan. Compared to equipment lacking dust treatment, it better meets environmental protection and safe production requirements. Attached Figure Description

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a plastic mold steel polishing equipment, including a workbench 1, a support frame 2 fixedly installed above the workbench 1, an installation groove 3 fixedly installed on one side of the upper surface of the support frame 2, an adjustment motor 4 fixedly installed on one side inside the installation groove 3, and a double-sided threaded rod 5 fixedly connected to the transmission end of the adjustment motor 4.

[0027] The end of the double-threaded rod 5 away from the adjusting motor 4 is connected to the mounting groove 3 through a bearing. The outer surface of the double-threaded rod 5 is connected to the internal thread adjusting block 6 by a thread. An adjusting plate 7 is fixedly connected to one side of the internal thread adjusting block 6. A polishing motor 8 is installed on the outer side of the two sets of adjusting plates 7. A polishing wheel 9 is fixedly connected to the transmission end of the polishing motor 8 through the adjusting plate 7.

[0028] Start the adjusting motor 4 in the mounting slot 3. The adjusting motor 4 drives the double-sided threaded rod 5 to rotate. Since the threads at both ends of the double-sided threaded rod 5 turn in opposite directions, the internal thread adjusting blocks 6 on both sides will move towards or away from each other along the threaded rod, thereby driving the adjusting plate 7, polishing motor 8 and polishing wheel 9 to move. According to the width of the mold steel, the adjusting motor 4 can precisely control the distance between the two sets of polishing wheels 9, so that the polishing wheels 9 fit against the two sides of the mold steel. Then start the polishing motor 8. The polishing motor 8 drives the polishing wheel 9 to rotate at high speed, polishing the two sides of the mold steel at the same time. When it is necessary to polish mold steel of different widths, start the adjusting motor 4 again, adjust the rotation of the double-sided threaded rod 5, and adjust the spacing of the polishing wheels 9.

A connecting frame 12 is fixedly connected to one side of the fixed seat 11. An electric push rod 13 is installed on the upper surface of the connecting frame 12. A push rod 14 is fixedly connected to the transmission end of the electric push rod 13 through the connecting frame 12. A pressure block 15 is fixedly connected to the end of the push rod 14 away from the electric push rod 13. The pressure block 15 corresponds to the fixed seat 11. A support block 16 is fixedly connected to the side of the adjusting plate 7 away from the internal thread adjusting block 6. A support groove 17 is fixedly installed on the side of the upper surface of the support frame 2 away from the mounting groove 3. The support block 16 is slidably connected to the support groove 17. A water storage chamber 18 is provided inside the workbench 1. A negative pressure fan 19 is fixedly installed on one side of the workbench 1. A filter shell 20 is provided on one side inside the water storage chamber 18. The filter shell 20 corresponds to the negative pressure fan 19. A sealing plate 21 is provided on the outer surface of the workbench 1.

[0030] When using this equipment for polishing plastic mold steel, the plastic mold steel to be polished is placed on the fixed seat 11 of the support mesh plate 10. Then, the electric push rod 13 on the connecting frame 12 is activated. The electric push rod 13 drives the push rod 14 and the pressure block 15 to move downwards until the pressure block 15 is in close contact with the upper surface of the mold steel. It cooperates with the fixed seat 11 to firmly clamp the mold steel. The pressure is precisely controlled by the electric push rod 13, which ensures that the mold steel will not shift during the polishing process. The support block 16 slides in the support groove 17, providing stable support and guidance for the adjusting plate 7, ensuring the stability and accuracy of the polishing wheel 9 during movement and polishing. During the polishing process, the negative pressure fan 1 is activated. 9. The negative pressure fan 19 creates a negative pressure environment in the water storage chamber 18 inside the workbench 1. Under the action of negative pressure, the dust generated during polishing is sucked into the water storage chamber 18 through the gaps in the support mesh plate 10. The filter shell 20 intercepts the dust and impurities, causing them to be adsorbed and settled by the water under the action of gravity. The filtered gas is discharged through the negative pressure fan 19. The sealing plate 21 on the outer surface of the workbench 1 ensures the airtightness of the equipment, prevents dust leakage, effectively purifies the working environment, and avoids dust from harming the health of operators. After the equipment is used, the sealing plate 21 can be opened to clean and replace the water in the water storage chamber 18 and the dust intercepted by the filter shell 20, ensuring the continuous and effective operation of the dust treatment system.

[0031] Working Principle: When using this equipment for polishing plastic mold steel, the plastic mold steel to be polished is placed on the fixed seat 11 of the support mesh plate 10. Then, the electric push rod 13 on the connecting frame 12 is started. The electric push rod 13 drives the push rod 14 and the pressure block 15 to move downwards until the pressure block 15 is in close contact with the upper surface of the mold steel. It cooperates with the fixed seat 11 to firmly clamp the mold steel. The pressure is precisely controlled by the electric push rod 13 to ensure that the mold steel does not shift during the polishing process. The adjusting motor 4 in the mounting slot 3 is started. The adjusting motor 4 drives the double-sided threaded rod 5 to rotate. Since the threads at both ends of the double-sided threaded rod 5 turn in opposite directions, the internal thread adjusting blocks 6 on both sides will move towards or away from each other along the threaded rod, thereby driving the adjusting plate 7, polishing motor 8 and polishing wheel 9 to move. According to the width of the mold steel, the adjusting motor 4 can precisely control the distance between the two sets of polishing wheels 9 so that the polishing wheels 9 are in contact with the two sides of the mold steel. Then, the polishing motor 8 is started. The polishing motor 8 drives the polishing wheel 9 to rotate at high speed, polishing the two sides of the mold steel at the same time. The support block 16 slides within the support groove 17, providing stable support and guidance for the adjusting plate 7, ensuring the stability and accuracy of the polishing wheel 9 during movement and polishing. During polishing, the negative pressure fan 19 is activated, creating a negative pressure environment within the water storage chamber 18 inside the workbench 1. Under the negative pressure, the dust generated during polishing is drawn into the water storage chamber 18 through the gaps in the support mesh plate 10. The filter shell 20 intercepts the dust and impurities, causing them to be adsorbed and settled by water under gravity. The filtered gas... The dust is discharged through the negative pressure fan 19. The sealing plate 21 on the outer surface of the workbench 1 ensures the airtightness of the equipment, prevents dust leakage, effectively purifies the working environment, and avoids dust from harming the health of operators. When polishing mold steel of different widths is required, the adjusting motor 4 is started again, the double-sided threaded rod 5 is adjusted to rotate, and the spacing of the polishing wheel 9 is adjusted. After the equipment is used, the sealing plate 21 is opened to clean and replace the water in the water storage chamber 18 and the dust intercepted by the filter shell 20, ensuring the continuous and effective operation of the dust treatment system.
