Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and more specifically, to a burr-resistant plastic mold. Background Technology

[0002] In the mold industry, molds are various molds and tools used to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. Molds are tools used to make shaped items. These tools are composed of various parts, and different molds are composed of different parts. After the plastic molds are produced and processed, there will be many burrs on the surface. Burrs not only affect the surface quality of the product, but may also have adverse effects on subsequent assembly and use. In severe cases, they may prick or scratch the user's hand, causing injury to the user's hand.

[0003] Among them, the mold for anti-burr plastic products disclosed in application number CN202223570459.4 is also an increasingly mature technology. The mold uses a bidirectional threaded rod to rotate and drive two clamping plates to clamp and limit the two sides of the plastic product. Then, the rotating shaft is driven to rotate by a worm gear. The rotation of the rotating shaft drives the limiting plate to rotate at an angle. In turn, the rotation of the rotating shaft drives the plastic product inside the limiting plate to adjust the angle. Then, the deburring plate is driven to move horizontally by the first threaded rod. The first electric telescopic rod adjusts the vertical position of the deburring plate, which facilitates the mechanical removal of burrs on the surface of the plastic product.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] This type of mold generates a large amount of waste chips and dust during grinding. The waste chips easily fall from the deburring plate into the inside of the rectangular groove, making them inconvenient to clean. The dust can pollute the environment around the mold and endanger the personal safety of the workers. Utility Model Content

[0006] The purpose of this invention is to provide a burr-resistant plastic mold to solve the problem of waste chips and dust generated during polishing mentioned in the background art.

[0007] This utility model provides a burr-resistant plastic mold, including a moving device, a dust removal device, and a clamping device;

[0008] The mobile device includes a fixed frame at the top of the workbench, a Y-axis threaded rod and a Y-axis guide rod on the back of the fixed frame, the back of the Y-axis threaded rod extending out of the frame and connecting to the output end of the first micro motor, Y-axis moving blocks movably mounted on the outside of both the Y-axis threaded rod and the Y-axis guide rod, long strip plates connected to the symmetrical ends of the Y-axis moving blocks, an X-axis threaded rod and an X-axis guide rod respectively mounted between the long strip plates, one end of the X-axis threaded rod extending out of the long strip plate and connecting to the output end of the second micro motor, X-axis moving blocks mounted on the outside of both the X-axis threaded rod and the X-axis guide rod, and a square plate mounted on the top of each set of X-axis moving blocks;

[0009] The dust removal device includes a dust collection box located on the outer left side of the frame. An activated carbon plate is located inside the dust collection box near the top. A sliding groove is provided at the bottom of one side of the dust collection box, and a dust collection drawer is slidably installed therein. The outlet end of a negative pressure machine is provided through the top of the dust collection box, and the inlet end of the negative pressure machine is provided through one side of the frame.

[0010] In this embodiment, a first micro motor drives the Y-axis threaded rod to rotate, causing the Y-axis moving block to move linearly along the Y-axis threaded rod and the Y-axis guide rod. As the Y-axis moving block moves synchronously with the long plate, a second micro motor drives the X-axis threaded rod to rotate, causing the X-axis moving block to move linearly along the X-axis threaded rod and the X-axis guide rod. This, in turn, causes the X-axis moving block to move the square plate at the top, thus enabling the square plate to move in both the X and Y axes. The negative pressure machine draws in air from the dust collection box, creating a negative pressure state inside the dust collection box. This draws in the dust generated in the frame, and the activated carbon plate adsorbs odors from the air. As the air flows, the dust eventually accumulates inside the dust collection drawer.

[0011] In one embodiment of this utility model, the clamping device includes a mounting plate fixedly connected to the middle of both sides of the top of a square plate. An electric telescopic rod is provided through the symmetrical ends of the mounting plate. The telescopic ends of the electric telescopic rod are connected to the clamping plate through a convex disc. A square groove is opened on the front of the square plate and a burr drawer is slidably provided thereon. A filter plate is provided at the top of the burr drawer on the square plate.

[0012] In this solution, the electric telescopic rod is activated to move the clamping plates at the telescopic end closer or further apart, thereby facilitating the clamping or releasing of the mold. The telescopic end of the electric telescopic rod has a self-locking property after it stops. The burr drawer facilitates the collection of grinding debris, and the filter plate can block larger burrs, thus facilitating the cleaning of debris inside the burr drawer and burrs on the filter plate.

[0013] In one embodiment of this utility model, a frame is provided at the top of the workbench, and an electric motor is vertically installed through the middle of the top of the frame. The output end of the electric motor is connected to a cylinder, and a grinding disc is provided at the piston end of the cylinder.

[0014] In this solution, the cylinder is rotated synchronously by the electric motor, and the cylinder drives the grinding disc to move up and down synchronously. The piston end of the cylinder has a self-locking property after it stops. Through the cooperation of the electric motor and the cylinder, the grinding disc can achieve efficient grinding of the mold surface.

[0015] In one embodiment of this utility model, the front sides of the frame are hinged with doors, each door has an observation window in the middle, a magnetic strip is provided between the top and bottom of the frame, and a door groove is provided near the middle of the front of each door.

[0016] In this design, the door slot facilitates the free opening and closing of the cabinet door, the observation window allows for real-time monitoring of the polishing effect, and the magnetic strip has an adsorption property with the iron cabinet door, which can attract the magnetic strip when the cabinet door is closed to increase the sealing performance.

[0017] In one embodiment of this utility model, the workbench is provided with legs at all four corners of its bottom end and with reinforcing ribs in the middle. The bottom of each leg is provided with casters with wheel brakes. The top of the inside of the frame is provided with a light.

[0018] In this solution, the height and stability of the workbench are increased by the support legs, the structural strength of the support legs is increased by the reinforcing ribs, the casters make it easy to move the equipment to the designated position and then fix it with wheel brakes, and the lights increase the brightness inside the frame.

[0019] In one embodiment of this utility model, the Y-axis threaded rod extending out of the frame and the X-axis threaded rod extending out of the long strip are both fitted with bearing sleeves. The top of the Y-axis moving block is provided with a triangular block. The dust collection drawer and the burr drawer are each provided with a pull handle in the middle of one side. The opposite ends of the clamping plate are each provided with a rubber pad.

[0020] In this design, bearing sleeves reduce friction and wear between components, triangular blocks increase the structural strength between the Y-axis moving block and the long plate, pull handles facilitate the pulling of drawers, and rubber pads increase the friction between the clamping plate and the mold.

[0021] In one embodiment of this utility model, a ramp is provided on the front of the top of the workbench, and a switch panel is provided at the top of the ramp. The top of the switch panel is provided with a first micro motor switch, a second micro motor switch, a negative pressure machine switch, an electric telescopic rod switch, an electric motor switch, a cylinder switch, and a lighting switch. The switch panel is electrically connected to an external power supply.

[0022] In this solution, power is supplied to the electrical equipment through a switch panel, and independent switches provide independent protection for the electrical equipment.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] (1) The starting of the electric telescopic rod drives the clamping plates at the telescopic end to move closer or further apart, thus facilitating clamping or releasing the mold. The telescopic end of the electric telescopic rod has self-locking properties after stopping. The burr drawer is convenient for collecting grinding debris. The filter plate can block larger burrs, thus facilitating the cleaning of debris inside the burr drawer and burrs on the filter plate.

[0025] (2) Air is drawn into the dust collection box through the inlet of the negative pressure machine, so that the inside of the dust collection box is in a negative pressure state, and then the dust generated in the frame is drawn into the dust collection box. The activated carbon plate adsorbs the odor in the air. With the air flow, the dust eventually accumulates inside the dust collection drawer. When the dust in the dust collection drawer accumulates to a certain amount, the dust collection drawer can be pulled to slide out, so as to facilitate the cleaning of dust.

[0037] Please refer to the details. Figure 2 The mobile device 100 includes a fixed frame 110 at the top of a workbench 400. A Y-axis threaded rod 111 and a Y-axis guide rod 112 are respectively provided on the back of the fixed frame 110. The back of the Y-axis threaded rod 111 extends out of the frame 410 and is connected to the output end of the first micro motor 113. Y-axis moving blocks 114 are movably provided on the outside of both the Y-axis threaded rod 111 and the Y-axis guide rod 112. The symmetrical ends of the Y-axis moving blocks 114 are connected to long strips 115. X-axis threaded rods 116 and X-axis guide rods 117 are respectively provided between the long strips 115. One end of the X-axis threaded rod 116 extends out of the long strips 115 and is connected to the output end of the second micro motor 118. X-axis moving blocks 119 are provided on the outside of both the X-axis threaded rod 116 and the X-axis guide rod 117.

The front of the square plate 120 has a square groove and a burr drawer 313 is slidably provided. A filter plate 314 is provided at the top of the square plate 120 at the burr drawer 313.

[0042] In one specific embodiment, please refer to Figure 2By activating the electric telescopic rod 311, the activation of the electric telescopic rod 311 causes the clamping plates 312 at the telescopic end to move closer or further apart, thereby facilitating the clamping or releasing of the mold. The telescopic end of the electric telescopic rod 311 has a self-locking property after it stops. The mounting plate 310 is used to connect and support the electric telescopic rod 311. The burr drawer 313 facilitates the collection of grinding debris. The filter plate 314 can block larger burrs, thereby facilitating the cleaning of debris inside the burr drawer 313 and burrs on the filter plate 314.

[0043] Please see Figure 3 The top of the workbench 400 is equipped with a frame 410, and a motor 411 is vertically installed through the middle of the top of the frame 410. The output end of the motor 411 is connected to a cylinder 412, and a grinding disc 413 is installed on the piston end of the cylinder 412.

[0044] In one specific embodiment, please refer to Figure 3 By starting the motor 411 and the cylinder 412, the output end 411 of the motor 411 drives the cylinder 412 to rotate synchronously. The piston end of the cylinder 412 drives the grinding disc 413 to move up and down in a linear motion synchronously. The piston end of the cylinder 412 has a self-locking property after stopping. Through the cooperation of the motor 411 and the cylinder 412, the grinding disc 413 can achieve efficient grinding of the mold surface, remove burrs and achieve the required smoothness.

[0045] Please see Figure 3 The front sides of the frame 410 are hinged with doors 414. Each door 414 has an observation window 415 in the middle. A magnetic strip 416 is provided between the top and bottom of the frame 410. Door grooves are provided near the middle of the front of the doors 414.

[0046] In one specific embodiment, please refer to Figure 3 The door 414 can be opened and closed freely on the frame 410 through the door groove. The observation window 415 can observe the polishing effect in real time. The magnetic strip 416 has an adsorption property with the iron door 414 and can attract the magnetic strip 416 when the door 414 is closed to increase the sealing.

[0047] Please see Figure 3 The workbench 400 is equipped with support legs 417 at the four corners of its bottom and with reinforcing ribs in the middle. The bottom of each support leg 417 is equipped with casters 418 with wheel brakes. The top of the inside of the frame 410 is equipped with a light 419.

[0048] In one specific embodiment, please refer to Figure 3The height and stability of the workbench 400 are increased by the support legs 417, the structural strength of the support legs 417 is increased by the reinforcing ribs to prevent deformation of the support legs 417, the casters 418 make it easy to move the equipment to a designated position and then fix it with wheel brakes, and the lighting 419 increases the brightness inside the frame 410 to ensure that the real-time grinding effect can still be clearly seen when the cabinet door 414 is closed.

[0049] Please see Figure 2 Bearing sleeves are fitted on the Y-axis threaded rod 111 extending out of the frame 410 and the X-axis threaded rod 116 extending out of the long strip 115. A triangular block 121 is provided at the top of the Y-axis moving block 114. A pull handle is provided in the middle of one side of the dust collection drawer 212 and the burr drawer 313. Rubber pads are provided at the opposite ends of the clamping plate 312.

[0050] In one specific embodiment, please refer to Figure 2 The bearing sleeve reduces friction and wear between components, allowing the two threaded rods to rotate stably. The triangular block 121 increases the structural strength between the Y-axis moving block 114 and the long plate 115. The handle makes it easy to pull the drawer. The rubber pad increases the friction between the clamping plate 312 and the mold, preventing the mold from sliding.

[0051] Please see Figure 3 The top front of the workbench 400 has a ramp, and a switch panel 420 is set at the top of the ramp. The top of the switch panel 420 is respectively equipped with a first micro motor switch, a second micro motor switch, a negative pressure machine switch, an electric telescopic rod switch, an electric motor switch, a cylinder switch and a lighting switch. The switch panel 420 is electrically connected to an external power supply.

[0052] In one specific embodiment, please refer to Figure 3 The switch panel 420 provides power to the electrical equipment, and the independent switch provides independent protection for the electrical equipment.

[0053] This utility model provides a burr-resistant plastic mold, and its specific usage is as follows:

[0054] Before use: The staff will connect the external power supply, turn on the switch panel 420, and then turn on the first micro motor switch, the second micro motor switch, the negative pressure machine switch, the electric telescopic rod switch, the motor switch, the cylinder switch and the lighting switch in sequence. The lighting 419 increases the brightness inside the frame 410 to ensure that the real-time polishing effect can still be clearly seen when the box door 414 is closed.

[0055] In use: The activation of the electric telescopic rod 311 causes the clamping plates 312 at the telescopic end to move closer or further apart, thus facilitating the clamping or releasing of the mold. The telescopic end of the electric telescopic rod 311 has a self-locking property after stopping. The output end 411 of the motor 411 drives the cylinder 412 to rotate synchronously. The piston end of the cylinder 412 drives the grinding disc 413 to move up and down linearly synchronously. The piston end of the cylinder 412 has a self-locking property after stopping. Through the cooperation of the motor 411 and the cylinder 412, the grinding disc 413 can achieve efficient grinding of the mold surface, removing burrs to achieve the required smoothness. When adjusting the position of the mold to be ground, the first micro motor 113 drives the Y-axis threaded rod 111 to rotate, causing the external Y-axis moving block 114 to move linearly along the Y-axis threaded rod 111 and the Y-axis guide rod 112. As the Y-axis moving block 114 drives the long strip plate 115 to move synchronously, the long strip plate 115 moves synchronously. The long strip 115 is used as a fixing component to support the X-axis threaded rod 116 and the X-axis guide rod 117. The second micro motor 118 drives the rotation of the X-axis threaded rod 116, causing the external X-axis moving block 119 to move linearly along the X-axis along the X-axis threaded rod 116 and the X-axis guide rod 117. In turn, the X-axis moving block 119 drives the top square plate 120 to move, thereby realizing the movement of the square plate 120 in the X-axis and Y-axis directions. The inlet end of the negative pressure machine 213 draws in air from the dust collection box 210, making the inside of the dust collection box 210 a negative pressure state, thereby drawing the dust generated in the frame 410 into the dust collection box 210. The activated carbon plate 211 adsorbs odors in the air. With the airflow, the dust eventually accumulates inside the dust collection drawer 212. When the dust in the dust collection drawer 212 accumulates to a certain amount, the dust collection drawer 212 can be pulled out to facilitate dust cleaning.
