Description

Technical Field

[0001] The present application relates to the technical field of anti-corrosion equipment production equipment, and in particular to a rotational molding device for anti-corrosion equipment and an anti-corrosion equipment production process. Background Art

[0002] Roto-molding device is a device used to manufacture various plastic products. It uses molds and rotation to heat and soften the plastic raw materials and evenly attach them to the inner wall of the mold, and then cool and solidify to obtain the plastic products of the desired shape. The working principle of the roto-molding device is relatively simple. It mainly relies on the rotation of the mold and the heating and softening of the plastic raw materials to achieve the molding of the products. In the roto-molding process, the plastic raw materials are first placed in the mold, and then the mold begins to rotate. As the mold rotates, the plastic raw materials are gradually evenly distributed on the inner wall of the mold and softened by heat. When the plastic reaches a certain degree of softening, the mold continues to rotate and cool, so that the plastic gradually solidifies and takes shape. Finally, the mold is opened and the product is taken out. In the process of producing workpieces, the current roto-molding device has the problem that the finished workpieces are not easy to take out of the production mold. Summary of the invention

[0003] In order to improve the problem that the workpiece is not easy to remove from the roto-molding mold, the present application provides a roto-molding device for anti-corrosion equipment, comprising a base, a roto-molding table rotatably connected to the base, and a motor 1 for driving the roto-molding table to rotate horizontally, wherein the roto-molding table is provided with a support mechanism, a roto-molding mold and a motor 2;

[0005] The second motor is used to drive the rotational molding mold to rotate;

[0006] The rotational molding table is also provided with a driving mechanism for driving the two frames to move closer to or away from each other.

[0007] By adopting the above scheme, during the production of the workpiece, the screw is driven to rotate by motor 3 to open the two mold bodies, and the raw materials are placed in the mold body.

Then, motor 1 and motor 2 are started, and motor 1 drives the rotomolding mold to rotate vertically, and motor 2 drives the rotomolding mold to rotate horizontally to form the desired workpiece. After that, motor 1, motor 2 and the heating layer are turned off and cooled for a period of time, and then motor 3 is started to separate the two mold bodies. During the separation of the two workpiece bodies, the workpiece will fall down or stay in a mold body. When the workpiece stays in a mold body of the workpiece, it can be easily removed due to the large amount of workpiece leakage, thereby improving the production efficiency of the workpiece. Furthermore, a clamping mechanism is also provided on the roto-molding table, and the clamping mechanism includes two clamping claws symmetrically arranged on both sides of the roto-molding mold, and a slideway is provided on the corresponding roto-molding table.

[0011] Furthermore, a plurality of rubber pads are sleeved on the roller.

[0012] By adopting the above solution, after the roller abuts against the workpiece, the rubber pad is used to increase the friction with the workpiece, so that the clamping claw can fix the workpiece more firmly.

[0015] Furthermore, an elastic member is fixedly connected between the sliding seat and the platform.

[0016] By adopting the above solution, after the staff removes the workpiece between the two clamping claws, the staff releases the restriction on the sliding seat, and the sliding seat automatically resets under the action of the elastic member.

[0018] By adopting the above solution, when the staff needs to remove the workpiece between the two clamping claws, the two clamping claws can be moved in opposite directions by stepping on the pedal ring, thereby facilitating the removal of the workpiece between the two clamping claws.

[0019] Furthermore, a connecting piece is fixedly connected in the sliding channel along the length direction of the sliding channel, the cross-section of the connecting piece is circular, a connecting hole adapted to the connecting piece is provided on the sliding seat, the connecting piece is slidably connected to the connecting hole, a limiting piece is fixed on the connecting piece, a limiting groove adapted to the limiting piece is provided on the inner wall of the connecting hole, one end of the limiting groove extends to an end surface of the sliding seat, and the limiting piece is slidably connected to the limiting groove.

[0020] By adopting the above scheme, when the workpiece needs to be removed from between the two clamping claws, the staff first pulls the sliding seat to one side through the operating part to make the workpiece disengage from between the two mold bodies, and at the same time makes the limiting part disengage from the limiting groove, and then steps on the pedal ring to release the two clamping parts from clamping the workpiece, and then rotates the sliding seat to one side to make the clamping claws tilted, and the workpiece slides between the two clamping claws by itself.

[0021] Furthermore, an arrangement groove is provided on one side of the limit groove in the connecting hole along the length direction of the limit groove, a sliding groove is provided in the arrangement groove along the length direction of the connecting hole, a sliding member is slidably connected in the sliding groove, a return torsion spring is sleeved on the connecting member, the return torsion spring is located in the arrangement groove and sleeved on the connecting member, one end of the return torsion spring is fixedly connected to the sliding member, and the other end of the return torsion spring is fixedly connected to the connecting member.

[0022] By adopting the above solution, after the workpiece is separated from the two clamping claws, the torsion spring can provide an auxiliary force when the staff rotates and resets the sliding seat, so that the staff can reset the sliding seat more easily and conveniently.

[0024] 1. By setting the rotational molding mold into two symmetrical mold bodies, the workpiece will fall down or stay in one mold body during the separation of the two workpiece bodies.

[0040] A rotational molding mold 3 and a supporting mechanism 4 for supporting the rotational molding mold 3 are arranged on the rotational molding table 2. Specifically, the rotational molding mold 3 is arranged horizontally.

[0041] Reference Figure 3 and Figure 4 The rotational molding mold 3 consists of two symmetrically arranged mold bodies 31, and a heating layer 34 is provided on the outer periphery of the mold bodies 31. A protrusion 32 is provided on one of the mold bodies 31, and a groove 33 is provided on the other mold body 31. When the two mold bodies 31 are spliced ​​together to form the rotational molding mold 3, the protrusion 32 extends into the groove 33.

[0042] The corresponding supporting mechanism 4 includes two symmetrically arranged frames 41, and the two frames 41 correspond to the two mold bodies 31 one by one. The mold body 31 is rotatably connected to the frames 41, and a second motor 42 is fixedly installed on one of the frames 41, and the second motor 42 is used to drive the rotational molding mold 3 to rotate.

[0043] Reference Figure 5A track 21 is also provided on the roto-molding table 2. The track 21 can be a groove body opened on the roto-molding table 2, or a channel steel fixedly installed on the roto-molding table 2. In this case, in order to save cost and space, the track 21 is configured as a groove body opened on the roto-molding table 2, and a slider 411 adapted to the track 21 is fixedly connected to the bottom of the frame 41, and the slider 411 is slidably connected to the track 21.

[0044] The roto-molding table 2 is provided with a driving mechanism 5 for driving the two frames 41 to move closer to or away from each other. The roto-molding mold 3 can be opened and closed under the action of the driving mechanism 5 .

[0045] Specifically, the driving mechanism 5 uses a screw 51 and a motor 3 52. The screw 51 is set in the track 21, and the screw 51 passes through two sliders 411. Two sections of reverse threads are set on the screw 51. The two sliders 411 correspond to the two sliders 411 respectively. The sliders 411 are threadedly connected with the screw 51. The motor 3 52 is used to drive the screw 51 to rotate. The two frames 41 can be moved closer or farther away from each other by driving the screw 51 to rotate forward or reversely through the motor 3 52.

[0046] In the process of workpiece production, the screw 51 is driven to rotate by the motor 3 52 to open the two mold bodies 31, and the raw materials are placed in the mold body 31. Then, the two mold bodies 31 are closed together by the motor 3 52, and then the heating layer 34 on the surface of the mold body 31 is started to heat the mold body 31 so that the material in the rotational mold 3 is gradually melted, and then the motor 1 111 and the motor 2 42 are started. The motor 1 111 drives the rotational mold 3 to rotate vertically, and the motor 2 42 drives the rotational mold 3 to rotate horizontally to form the desired workpiece. After that, the motor 1 111, the motor 2 42 and the heating layer 34 are turned off and cooled for a period of time, and then the motor 3 52 is started to separate the two mold bodies 31. In the process of separating the two workpiece bodies, the workpiece will fall down or stay in a mold body 31. When the workpiece stays in a mold body 31 of the workpiece, it can be easily removed due to the large amount of workpiece leakage.

[0047] Reference Figure 6 Furthermore, a clamping mechanism 6 is also provided on the rotational molding table 2. When the rotational molding process of the workpiece is completed and the two mold bodies 31 are separated, the clamping mechanism 6 is used to fix the workpiece so that the workpiece can be separated from the rotational molding mold 3 during the separation of the two mold bodies 31.

[0048] Specifically, the clamping mechanism 6 includes two symmetrically arranged clamping claws 61 , and the two clamping claws 61 are respectively arranged on two sides of the rotational molding mold 3 .

[0049] Reference Figure 7.At the same time, a slideway 24 is provided on the roto-molding table 2, and a slider 411 is fixedly connected to the bottom of the clamping claw 61, and the slider 411 is slidably connected to the slideway 24, and an elastic member 611 is fixedly connected between the clamping claw 61 and the roto-molding table 2. The elastic member 611 is generally a spring. Under the action of the elastic member 611, the two clamping claws 61 are pressed against the roto-molding mold 3. After the workpiece in the roto-molding mold 3 is formed, during the separation of the two mold bodies 31, the two clamping claws 61 hold the workpiece tightly under the action of the elastic member 611, and the workpiece can be separated from the roto-molding mold 3 more smoothly. At the same time, during the process of disassembling the workpiece, since there is still residual temperature on the workpiece, the clamping mechanism 6 can play a role of transition buffer to improve the disassembly efficiency.

[0050] Furthermore, in order to enable the clamping claw 61 to grip the workpiece as soon as the two mold bodies 31 are separated, the clamping claw 61 is pressed against the gap between the two mold bodies 31 under the action of the elastic member 611 .

[0051] Reference Figure 4 In order to reduce the wear of the clamping claws 61 during the rotation of the rotational molding mold 3 , an annular abutment area 35 is provided on the rotational molding mold 3 , and the abutment area 35 covers the connection position of the two mold bodies 31 on the rotational molding mold 3 .

[0052] Reference Figure 8 and Fig. 9 At the same time, a plurality of rollers 612 are rotatably connected to the inner side of the clamping claw 61, and the rotation axis of the rollers 612 is parallel to the rotation axis of the rotational molding mold 3. During the rotation of the rotational molding mold 3, the rollers 612 can roll on the abutment area 35 on the rotational molding mold 3 to reduce the wear of the clamping claw 61 and the rotational molding mold 3.

[0053] The roller 612 is a cylindrical roller 612 , and a plurality of rubber pads 6121 are wound around the outer circumference of the roller 612 . After the roller 612 abuts against the workpiece, the rubber pads 6121 are used to increase the friction with the workpiece, so that the clamping claw 61 can fix the workpiece more firmly.

[0054] Reference Figure 5 Furthermore, the rotational molding table 2 includes a table body 22 and a sliding seat 23 . A sliding channel 221 is opened on the table body 22 , and the sliding seat 23 is slidably connected to the sliding channel 221 .

[0055] Reference Figure 6 An elastic member 231 is fixedly connected between the sliding seat 23 and the platform 22, and the elastic member 231 is generally a spring.

[0056] Reference Figure 7The slideway 24 is opened on the sliding seat 23, and the elastic member 611 is fixed between the clamping claw 61 and the sliding seat 23. After the workpiece is separated from the rotational molding mold 3 and clamped and fixed by the two clamping claws 61, the staff pulls the sliding seat 23 to one side to make the workpiece separate from between the two mold bodies 31, which is convenient for disassembly of the workpiece. After the staff removes the workpiece between the two clamping claws 61, the staff releases the restriction on the sliding seat 23, and the sliding seat 23 automatically resets under the action of the elastic member 231.

[0057] Reference Figure 6 The operating member 7 is fixedly connected to the sliding seat 23, so that the staff can slide the sliding seat 23. The operating member 7 includes a vertical portion 71 and a horizontal portion 72 which are integrally arranged. The bottom of the vertical portion 71 is fixedly connected to the sliding seat 23, and a pedal ring 8 is arranged on one side of the vertical portion 71.

[0058] Reference Fig.10 The horizontal portion 72 is horizontally arranged along the length direction of the sliding seat 23 and is located directly above the two clamping claws 61. Two guide members 721 are arranged on the horizontal portion 72. The two clamping claws 61 are located between the two guide members 721, and the two guide members 721 correspond to the two clamping claws 61 one by one. The clamping claws 61 are fixedly connected with guide wires 81, which pass upward around the guide members 721 and are fixedly connected to the pedal ring 8. When the staff needs to remove the workpiece between the two clamping claws 61, the two clamping claws 61 can be moved in opposite directions by stepping on the pedal ring 8, so as to facilitate the removal of the workpiece between the two clamping claws 61.

[0059] In order to reduce the friction between the guide wire 81 and the guide member 721, the guide member 721 and the horizontal portion 72 are gradually configured to be rotationally connected.

The connecting piece 9 is slidably connected to the connecting hole 232. The outer peripheral surface of the connecting piece 9 is fixedly connected to a limiting piece 91. A limiting groove 2321 is arranged along the length direction of the connecting hole 232 on the inner wall of the corresponding connecting hole 232. One end of the limiting groove 2321 extends to one end surface of the sliding seat, and the limiting piece 91 is slidably connected to the limiting groove 2321. When the workpiece needs to be removed from between the two clamping claws 61, the staff first pulls the sliding seat 23 to one side through the operating member 7 to make the workpiece disengage from between the two mold bodies 31, and at the same time makes the limiting member 91 disengage from the limiting groove 2321, and then steps on the pedal ring 8 to release the clamping of the two clamping members on the workpiece, and then rotates the sliding seat 23 to one side to make the clamping claws 61 tilted, and the workpiece slides between the two clamping claws 61 by itself.

[0061] An annular arrangement groove 2322 is provided on one side of the limit groove 2321 in the connection hole 232 along the length direction of the limit groove 2321, a slide groove 2323 is provided in the arrangement groove 2322 along the length direction of the arrangement groove 2322, a sliding member 921 is slidably connected in the slide groove 2323, a return torsion spring 92 is provided on the outer sleeve of the connection member 9, the return torsion spring 92 is located in the arrangement groove 2322, one end of the return torsion spring 92 is fixedly connected to the connection member 9, and the other end of the return torsion spring 92 is fixedly connected to the sliding member 921. After the workpiece is separated from the two clamping claws 61, when the staff rotates and resets the sliding seat 23, the return torsion spring 92 can provide an auxiliary force, so that the staff can reset the sliding seat 23 more easily and conveniently.

[0062] The implementation principle of this case is: in the process of workpiece production, the screw 51 is driven to rotate by motor three 52 to open the two mold bodies 31, and the raw materials are placed in the mold body 31. Then, the two mold bodies 31 are closed together by motor three 52, and then the heating layer 34 on the surface of the mold body 31 is started to heat the mold body 31 so that the material in the rotational molding mold 3 is gradually melted, and then the motor one 111 and the motor two 42 are started. The motor one 111 drives the rotational molding mold 3 to rotate in the vertical direction, and the motor two 42 drives the rotational molding mold 3 to rotate in the horizontal direction to form the required workpiece. After that, turn off motor 1 111, motor 2 42 and heating layer 34 and cool for a while, start motor 3 52 to separate the two mold bodies 31. During the separation of the two workpiece bodies, the two clamping claws clamp the workpiece. After the two mold bodies 31 are completely separated from the workpiece, the staff pulls the sliding seat 23 to one side through the operating part 7 to make the workpiece separate from between the two mold bodies 31, and at the same time makes the limit member 91 separate from the limit groove 2321, and then steps on the pedal ring 8 to release the clamping of the workpiece by the two clamping members, and then rotates the sliding seat 23 to one side to make the clamping claw 61 tilted, and the workpiece slides between the two clamping claws 61 by itself.
