[0002] A plastic mold is a tool that is matched with a plastic molding machine in the plastic processing industry and gives plastic products a complete configuration and precise dimensions. Due to the variety of plastic varieties and processing methods, and the complexity of the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse. When producing plastic molds, after the holes of the plastic molds are opened, the inner walls of the holes need to be ground to eliminate the bumps or burrs on the inner walls of the holes, so as to ensure the smoothness of the inner walls of the holes after the plastic molds are opened.

[0003] During the grinding process of the inner walls of the holes of the plastic molds, the waste chips generated by the grinding of the inner walls of the holes are easily attached to the inner walls.

[0015] The present invention further includes a grinding method for a hole wall grinding device for plastic mold processing, including the following steps:

[0016] S01: First, place the plastic mold with holes on the clamping assembly, and then fix the plastic mold through the clamping assembly.

[0017] S02: Then, start the water pump, pump the coolant inside the collection box into the annular tube through the water pump, and then evenly spray the coolant on the holes of the plastic mold through the spray head. Then start the electric push rod and the second motor, so that the grinding head drills into the holes of the plastic mold, thereby completing the grinding of the holes.

[0018] S03: Drive the first cross plate to move downward through the electric push rod, and then drive the wiping assembly to move downward through the mounting plate, so that the wiping cloth wheel in the wiping assembly moves into the cleaning assembly to complete the cleaning of the wiping cloth wheel. Then, through the wiping assembly, the wiped cloth wheel after cleaning is flipped 180°, so that the cleaned wiping cloth wheel faces the holes of the plastic mold. Then, control the grinding head to move upward through the electric push rod, and then drive the wiping cloth wheel in the wiping assembly to move upward to the holes of the plastic mold, thereby completing the cleaning of the debris adhering to the hole wall.

[0019] The present invention has the following beneficial effects: 1. During the grinding process of the holes in the plastic mold, after synchronously rotating and cleaning the wiping cloth wheel, the inner wall of the hole is cleaned, avoiding the labor intensity of manual cleaning, effectively improving the efficiency of grinding the holes in the plastic mold and the cleanliness of the inner wall of the hole, thereby improving the quality of the plastic mold.

[0020] 2. The installation plate drives the wiping cloth wheel and the first toothed plate to move upward, causing the first toothed plate to drive the spur gear to rotate in the reverse direction, and then driving the lead screw to rotate in the reverse direction, so that the two lead screws drive the two moving plates to move towards each other, and then drive the two scrubbing arc plates to move towards each other through the two moving rods, reducing the distance between the two scrubbing arc plates, thus having an extrusion effect on the water-containing wiping cloth wheel, squeezing out the water in the wiping cloth wheel, reducing the water content of the wiping cloth wheel, making the wiping cloth wheel dry, and making the subsequent cleaning effect of the holes in the plastic mold better.

[0021] 3. By energizing the first solenoid valve and the second solenoid valve, the L-shaped adapter pipe and the intake pipe are closed. Then, the installation plate moves downward, and the installation plate drives the piston plate to move downward through the L-shaped push rod, causing the piston plate to squeeze the air inside the compression pipe, so that the air below the piston plate in the compression pipe is compressed, thereby increasing the air pressure in the compression pipe. Then, the first solenoid valve is opened, and the pressurized air in the compression pipe flows into the sleeve through the L-shaped adapter pipe, thereby pushing the push plate to move away from the water storage box, and then driving the power toothed plate to move away from the water storage box through the L-shaped power rod, causing the power toothed plate to engage and drive the power gear to rotate, driving the power gear to drive the second rotating rod and the disc to rotate, and then driving the two scrubbing arc plates to rotate reciprocally, providing power for the rotation of the scrubbing arc plates.

[0022] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0044] Example 1, please refer to Figure 1-17, the present invention provides the following technical solution: A hole wall grinding device for plastic mold processing, including a grinding assembly 1; the grinding assembly 1 includes a collection box 101, a grinding head 102 is arranged on the top of the collection box 101, an annular pipe 103 is sleeved on the grinding head 102, and a plurality of spray nozzles 104 are communicated and arranged on the outer peripheral side of the annular pipe 103. A clamping assembly 2 adapted to the grinding head 102 is fixedly engaged on the grinding assembly 1; a wiping assembly 3 is fixedly engaged on the inner bottom of the collection box 101. The wiping assembly 3 includes a first L-shaped rod 301 fixedly connected to the inner bottom of the collection box 101. The end of the first L-shaped rod 301 is fixedly connected with a first motor 302. The output end of the first motor 302 is fixedly connected with a guide cylinder 303. A first chute 304 is opened on the inner peripheral side of the guide cylinder 303, and a through second chute 305 is opened on the outer peripheral side of the guide cylinder 303; a cylindrical rod 314 is slidably engaged on the inner peripheral side of the guide cylinder 303. Wiping cloth wheels 306 are symmetrically fixedly connected to the peripheral side of the cylindrical rod 314. A first sliding rod 307 slidably engaged with the first chute 304 is fixedly connected to the peripheral side of the cylindrical rod 314. A second sliding rod 308 slidably connected to the second chute 305 is fixedly connected to the peripheral side of the cylindrical rod 314; the end of the second sliding rod 308 is rotatably connected with a mounting plate 309. A connecting rod 310 is fixedly connected to the top of the mounting plate 309. The top end of the connecting rod 310 is fixedly connected with a first cross plate 311 fixedly engaged with the grinding assembly 1; special-shaped rods 312 are fixedly connected to the opposite side surfaces of the mounting plate 309. A first toothed plate 313 is fixedly connected to the end of the special-shaped rod 312; a cleaning assembly 4 is fixedly engaged on the inner bottom of the collection box 101.

[0045] The operation process of this embodiment is as follows: First, place the plastic mold with holes on the clamping assembly 2, and then fix the plastic mold through the clamping assembly 2 to ensure the stability during the hole grinding operation of the plastic mold; Next, control the coolant in the annular pipe 103 to pass through the spray nozzles 104, and evenly spray the coolant on the holes of the plastic mold to cool down during the hole grinding process, thereby effectively preventing the plastic mold from deforming, and thus improving the quality of the plastic mold. Subsequently, while controlling the rotation of the grinding head 102, control the grinding head 102 to move closer to the inside of the hole of the plastic mold, so that the grinding head 102 completes the grinding of the inner wall of the hole;

[0046] By controlling the grinding head 102 to move downward, the connecting rod 310 is driven downward through the first cross plate 311 synchronously, and then the cylindrical rod 314 is driven to move toward the direction close to the cleaning component 4 through the mounting plate 309, and then the wiping cloth wheel 306 below is driven to move toward the direction close to the cleaning component 4. After the grinding head 102 completes the grinding of the holes in the plastic mold (synchronously controlling the coolant to stop spraying), the wiping cloth wheel 306 below is now cleaned in the cleaning component 4, and then the grinding head 102 is controlled to move upward, synchronously driving the cylindrical rod 314 and the wiping cloth wheel 306 to move upward, so that the wiping cloth wheel 306 is located inside the guide cylinder 303, and then the first motor 302 is controlled to drive the guide cylinder 303 to rotate 180° (this The grinding head 102 is controlled to be stationary at the same time), so that the wiping cloth wheel 306 located below after cleaning rotates to be vertically upward and aligned with the hole, and then the grinding head 102 is continued to be controlled to move, thereby synchronously driving the cylindrical rod 314 and the wiping cloth wheel 306 to move upward, so that the wiping cloth wheel 306 moves toward the inside of the hole, thereby completing the cleaning of the debris and coolant sticking on the inner wall of the hole, thereby quickly completing the cleaning of the inner wall of the hole, and then repeating the above operation to achieve the grinding of the inner wall of the hole by the grinding head 102, and the cleaning of the inner wall of the hole by rotation of the wiping cloth wheel 306, thereby avoiding the labor of manual cleaning, effectively improving the efficiency of grinding the holes of the plastic mold, and the cleanliness of the inner wall of the hole, thereby improving the quality of the plastic mold.

An arc-shaped liquid shielding plate 113 is fixedly connected between the two fixing rods 112. A sealing plate 114 connected by a torsion spring is hinged to the top of the arc-shaped liquid shielding plate 113. A plurality of diversion grooves 115 are evenly formed on the inner peripheral side surface of the arc-shaped liquid shielding plate 113. A filter plate 116 is fixedly connected to the inner bottom of the collection box 101. A first guiding groove 117 is formed on the inner bottom of the collection box 101. A control box 118 is fixedly connected to an outer side surface of the U-shaped plate 106.

[0048] The clamping assembly 2 includes an operating table 201. A plurality of support columns 202 are symmetrically and fixedly connected to the top of the operating table 201. The plurality of support columns 202 are fixedly fitted with the U-shaped plate 106. The operating table 201 is fixedly fitted with the two second L-shaped rods 111.

[0050] By starting the water pump 109, the coolant inside the collection box 101 is pumped into the annular pipe 103 through the water pump 109, and then the coolant is evenly sprayed on the holes of the plastic mold through the nozzle 104. Through the provided filter plate 116, the filter plate 116 filters the waste chips in the coolant, thereby ensuring the cleanliness during the recycling of the coolant and avoiding secondary pollution caused by the waste chips mixed in the coolant during the grinding process of the holes of the plastic mold.

[0051] Through the use of the provided arc-shaped liquid shielding plate 113 and the sealing plate 114 (the sealing plate 114 is connected by a torsion spring, so that the sealing plate 114 can rotate forward and backward, thus not affecting the normal passing of the wiping cloth wheel 306 and the grinding head 102), the coolant flows into the collection box 101 along the outer surface of the arc-shaped liquid shielding plate 113, thereby shielding and protecting the wiping cloth wheel 306 and the cleaning assembly 4 and avoiding pollution caused by the cleaning liquid.

[0052] By controlling the electric push rod 107 to drive the first cross plate 311 and the second motor 108 to move up or down, and then driving the grinding head 102 to move up or down, synchronously controlling the second motor 108 to drive the grinding head 102 to rotate, thereby providing power for the movement and rotation of the grinding head 102 and the up and down movement of the first cross plate 311.

The cleaning assembly 4 includes a water storage box 401 fixedly fitted on the inner bottom of the collection box 101 (the water storage box 401 is filled with water). Symmetric second guiding grooves are opened at the inner top of the water storage box 401. A slider 402 is slidably connected inside the second guiding grooves. The top of the slider 402 is fixedly connected with an arc-shaped plate 403. An arc-shaped groove 404 is opened at the top of the arc-shaped plate 403. An arc-shaped block 405 is slidably connected inside the arc-shaped groove 404. The top of the arc-shaped block 405 is fixedly connected with a top rod 406. The top end of the top rod 406 is fixedly connected with a rubbing arc plate 407. An arc-shaped toothed plate 408 is fixedly connected to the outer peripheral side of the rubbing arc plate 407.

The adjacent lead screw 411 and the moving plate 410 are in threaded cooperation. A spur gear 412 is fixedly connected to the end of the lead screw 411. A drain pipe 413 communicating with the outside of the collection box 101 is arranged on one inner side surface of the water storage box 401. A valve is installed on the drain pipe 413.

[0054] The operation process of this embodiment is as follows: By moving the first cross plate 311 downward, the mounting plate 309 is driven to move downward, and then the first tooth plate 313 is driven to move downward through the special-shaped rod 312 (in the initial state, the first tooth plate 313 is located above the spur gear 412 and does not mesh with the spur gear 412). During the process of the grinding head 102 finishing the grinding of the holes of the plastic mold, the first tooth plate 313 is synchronously moved downward to mesh with the spur gear 412, so that the spur gear 412 drives the lead screw 411 to rotate, and the two lead screws 411 drive the two moving plates 410 to move away from each other. Then, the two scrubbing arc plates 407 are driven to move away from each other through the two moving rods 409 (the distance between the two scrubbing arc plates 407 is slightly larger than the diameter of the cylindrical rod 314 initially). The distance between the two scrubbing arc plates 407 is made to be between the diameter of the cylindrical rod 314 and the diameter of the wiping cloth wheel 306. Then, the two scrubbing arc plates 407 are controlled to rotate reciprocally, and the two scrubbing arc plates 407 clean the wiping cloth wheel 306, thus ensuring the cleanliness of the wiping cloth wheel 306;

[0055] After the cleaning is completed, the electric push rod 107 drives the grinding head 102 and the first cross plate 311 to move upward, so that the wiping cloth wheel 306 and the first tooth plate 313 are driven to move upward through the mounting plate 309. The first tooth plate 313 drives the spur gear 412 to rotate in the reverse direction, and then drives the lead screw 411 to rotate in the reverse direction. The two lead screws 411 drive the two moving plates 410 to move towards each other. Then, the two scrubbing arc plates 407 are driven to move towards each other through the two moving rods 409, and the distance between the two scrubbing arc plates 407 becomes smaller, so as to have an extrusion effect on the water-containing wiping cloth wheel 306, squeeze out the water in the wiping cloth wheel 306, reduce the water content of the wiping cloth wheel 306, make the wiping cloth wheel 306 dry, and make the subsequent cleaning effect of the holes of the plastic mold better.
