Description

Technical Field

[0001] The invention belongs to the technical field of rubber and plastic product processing, and particularly relates to a forming mold for rubber and plastic products. Background Art

[0002] Injection molding is an important manufacturing process widely used in the production of rubber and plastic products. This process involves injecting molten plastic into a mold cavity under high pressure, cooling and solidifying it to produce the desired shape. Injection molding has the advantages of high production efficiency, low cost, and high product precision, and is therefore widely used in the automotive, electronics, and home appliance industries.

[0003] In the traditional process of injection molding rubber and plastic products, demoulding is undoubtedly the key to the entire production process. In order to ensure that the rubber and plastic products can be smoothly demoulded after injection molding, the current common practice is to rely on manual operation to spray the mold with a release agent before injection molding.

A second horizontal plate 92 is inserted into the horizontal slot 91 opened on one side of the rectangular box 1.

The interior of the rectangular box 1 is fixedly connected to a hard connecting tube 95, one end of the hard connecting tube 95 is inserted into the surface of the built-in box 93, and the hard connecting tube 95 is connected to the interior of the built-in box 93.

[0059] Working principle: When the rubber and plastic products need to be injection molded, the electric hydraulic push rod 66 is connected to the external power supply, and the operation of the electric hydraulic push rod 66 is controlled by the controller. When the telescopic rod of the electric hydraulic push rod 66 drives the first horizontal plate 618 to move upward, when the two ends of the first horizontal plate 618 respectively fit with the top of the groove wall of the right chute 73 and the left chute 724, as the first horizontal plate 618 moves upward, the right rectangular sleeve 68 and the left rectangular sleeve 67 are synchronously moved upward, so that the right rectangular sleeve 68 slides on the surface of the right support rod 65, and the right rectangular sleeve 67 is moved upward. The movement of 8 drives the first U-shaped block 69 to move, and then drives the first connecting plate 610 to rotate inside the first U-shaped block 69. The movement of the first connecting plate 610 drives the second connecting plate 612 to rotate inside the second U-shaped block 614, so that the insertion shaft 616 slides inside the hollow groove 613, and then pushes the U-shaped connecting plate 615 to slide inside the first slot 617. The movement of the U-shaped connecting plate 615 drives the right mold 3 to move toward the direction close to the left mold 2 until the surfaces of the right mold 3 and the left mold 2 are tightly fitted to each other. At this time, the injection molding process can be carried out;

[0060] Since the right mold 3 has an injection hole 5 inside, and an injection tube 4 is inserted into the injection hole 5, the other end of the injection tube 4 is connected to the container storing the rubber and plastic raw material solution through a delivery pump, and according to the injection molding process requirements, the flow rate, pressure and other parameters of the delivery pump are set to ensure that the raw material solution can be delivered to the right mold 3 at a suitable flow rate and pressure. The injection tube 4 can be deformed under the action of external force and will not hinder the movement of the right mold 3. After the left mold 2 and the right mold 3 are closed, the delivery pump is started to inject the rubber and plastic raw material solution in the storage container into the injection hole 5 of the right mold 3 through the injection tube 4 under high pressure, thereby filling the entire mold cavity;

[0061] After the mold is formed, the electric hydraulic push rod 66 is started again, so that its telescopic rod drives the first horizontal plate 618 to move downward. In the process of the first horizontal plate 618 moving downward, the right rectangular sleeve 68 and the left rectangular sleeve 67 are moved downward synchronously under the action of the two U-shaped counterweight rods 619. According to the above principle of moving the right mold 3 toward the left mold 2, the first U-shaped block 69, the first connecting plate 610, the rotating optical axis 611, the second connecting plate 612, the plug shaft 616 and the U-shaped connecting plate 615 are used to move the right mold 3 toward the left mold 2. 618 moves downward so that the right rectangular sleeve 68 moves downward, which can cause the right mold 3 to move in the direction away from the left mold 2, until the right rectangular sleeve 68 moves to fit the upper surface of the right clamping plate 62, and then the right rectangular sleeve 68 cannot move, thereby preventing the right mold 3 from moving further. At this time, the injection-molded rubber and plastic product can be removed from the surface of the left mold 2. It is beneficial to control the operation of the electric hydraulic push rod 66 to move the right mold 3 in the direction close to or away from the left mold 2, thereby conveniently realizing the injection molding process of the rubber and plastic product.

[0062] Before injection molding of the plastic product, the lower side plate 712 can be rotated first so that the spray release agent 78 is inserted into the inside of the sealing ring 79, and the force applied to the lower side plate 712 is released. Under the action of the gravity of the first counterweight block 713, the bottom stop shaft 714 can be rotated to the bottom of the spray release agent 78, and the button-type joint of the spray release agent 78 is close to the bottom stop shaft 714. At this time, the bottom end of the built-in sliding shaft 75 is in contact with the top of the spray release agent 78. In the process of the telescopic rod of the electric hydraulic push rod 66 driving the first horizontal plate 618 to move downward, when the right rectangular sleeve 68 and the right card When the upper surface of the plate 62 is in contact with each other, and the upper surface of the left rectangular sleeve 67 and the left card plate 61 are in contact with each other, the right rectangular sleeve 68 and the left rectangular sleeve 67 can no longer move. As the first cross plate 618 moves, the movement of the first cross plate 618 drives the built-in plug rod 720 to move synchronously. The movement of the built-in plug rod 720 drives the semi-cylindrical block 722 to slide out from the inside of the right-angled trapezoidal groove 721 and slide to the inside of the left slide groove 724. In this process, the built-in plug rod 720 drives the fourth U-shaped block 717 to slide inside the stepped groove 718 and squeeze the first spring 719, so that the fourth U-shaped block 717 moves to the left. In the process of moving in the direction of the first spring 719, the third U-shaped block 715 is pushed downward by the inclined connecting rod 716. The movement of the third U-shaped block 715 drives the built-in sliding shaft 75 to move downward inside the lower shaft sleeve 74, so that the built-in sliding shaft 75 squeezes the spray release agent 78, causing the spray release agent 78 to move downward. As the spray release agent 78 moves downward, the bottom stop shaft 714 presses the button-type joint of the spray release agent 78. At this time, the release agent inside the spray release agent 78 is sprayed from the nozzle on the button-type joint of the spray release agent 78 to the left mold 2, and the electric hydraulic The telescopic end of the push rod 66 drives the first transverse plate 618 to move to the extreme position, which is conducive to the left rectangular sleeve 67 and the upper surface of the left card plate 61 being in contact with each other. As the telescopic rod of the electric hydraulic push rod 66 continues to drive the first transverse plate 618 to move downward, the built-in sliding shaft 75 presses the spray release agent 78, thereby achieving the effect of pressing the button-type joint of the spray release agent 78 through the bottom stop shaft 714, and then realizing the release agent from the nozzle on the button-type joint of the spray release agent 78 to the left mold 2, so that the rubber and plastic product after injection molding is demolded from the left mold 2, thereby improving the molding efficiency of the rubber and plastic product;

[0063] During this process, the downward movement of the first horizontal plate 618 drives the inclined pressure plate 89 and the tooth plate 82 to move downward synchronously, and the movement of the tooth plate 82 drives the auxiliary optical axis 820 to slide inside the right-angle slide groove 819. When the right rectangular sleeve 68 does not move and the first horizontal plate 618 moves downward, the inclined pressure plate 89 moves in the direction away from the lower pressure plate 817, that is, the inclined pressure plate 89 and the lower pressure plate 817 are separated, so that the lower pressure plate 817 no longer applies a force to the inclined pressure plate 89, and under the action of the gravity of the second counterweight block 812, the bottom surface of the inclined pressure plate 89 and the tooth plate 82 are One end fits together and applies force to the tooth plate 82, and the auxiliary optical axis 820 is inserted into the inside of the right-angle slide groove 819, and the tooth plate 82 moves downward under the restriction of the shape of the right-angle slide groove 819. When the auxiliary optical axis 820 slides out from the inside of the right-angle slide groove 819, the inclined pressure plate 89 applies force to the tooth plate 82, which allows the tooth plate 82 to slide on the surface of the T-shaped slide bar 81 and continue to move a suitable distance until the first limit shaft 811 fits against the bottom surface of the inclined pressure plate 89, and the first horizontal plate 618 stops moving downward. At this time, the auxiliary optical axis 820 moves from the longitudinal direction to the longitudinal direction. When the guide plate 815 is moved out from below, and the telescopic rod of the electric hydraulic push rod 66 drives the first cross plate 618 to move upward, the inclined pressure plate 89 is fitted with the surface of the first limit shaft 811, which can limit the position of the inclined pressure plate 89, and the elastic potential energy of the second spring 86 is squeezed to limit the position of the tooth plate 82 after it moves. The movement of the tooth plate 82 drives the gear 84 meshed with it to rotate, and the rotation of the gear 84 drives the upper shaft 71 to rotate, and then drives the lower shaft sleeve 74 to rotate. Since the inclined pressure plate 89 rotates to the first limit shaft 811 When the surfaces of the lower sleeve 74 are in contact with each other, the tooth plate 82 moves a distance that is just enough to allow the lower sleeve 74 to rotate 180 degrees, so that the nozzle on the button-type joint of the spray-type mold release agent 78 can be sprayed toward the right mold 3. In addition, during the rotation of the lower sleeve 74, the third U-shaped block 715 can rotate inside the fan-shaped groove 76. The third U-shaped block 715 does not hinder the rotation of the lower sleeve 74. After the lower sleeve 74 rotates 180 degrees, as the first horizontal plate 618 moves upward, the nozzle on the button-type joint of the spray-type mold release agent 78 is sprayed toward the right mold 3, thereby facilitating the demolding of the rubber-plastic product from the right mold 3 after injection molding.

[0064] As the first transverse plate 618 continues to move upward, when the bottom end of the lower pressing plate 817 is in contact with the inclined pressing plate 89, and as the first transverse plate 618 continues to move, the inclined pressing plate 89 rotates around the second limiting shaft 814, so that the inclined pressing plate 89 no longer exerts a force on the toothed plate 82. Under the action of the elastic potential energy of the compressed second spring 86, the toothed plate 82 is pushed, so that the auxiliary optical axis 820 slides into the interior of the right-angled groove 819, thereby facilitating the injection molding of the plastic product again.

[0065] When the first horizontal plate 618 moves upward to a position where the semi-cylindrical block 722 slides into the right-angled trapezoidal groove 721, the semi-cylindrical block 722 slides into the right-angled trapezoidal groove 721 under the action of the first spring 719, thereby causing the built-in insertion rod 720 to drive the tilting link 716 to move, thereby pulling the built-in sliding shaft 75 to move upward. At this time, the built-in sliding shaft 75 no longer squeezes the spray release agent 78, so that the release agent no longer sprays out from the nozzle on the button-type connector of the spray release agent 78;

[0066] When the first cross plate 618 moves up or down, the position between the first cross plate 618 and the right rectangular sleeve 68 does not change, that is, under the action of the gravity of the U-shaped counterweight rod 619, when the first cross plate 618 moves up or down, the position between the first cross plate 618 and the right rectangular sleeve 68 does not change, until the right rectangular sleeve 68 and the surface of the right clamping plate 62 are in contact with each other, the first cross plate 618 moves down, and the first cross plate 618 can slide inside the right side slot 73 of the first cross plate 618 and the right rectangular sleeve 68. Under the action of the gravity of the U-shaped counterweight rod 619, the first cross plate 618 can slide inside the right side slot 73 without driving the right rectangular sleeve 68 to move. Until the first cross plate 618 and the inner wall of the top of the right slot 73 are in contact with each other, the first cross plate 618 moves up, and the right rectangular sleeve 68 can be driven up.

[0067] The mold release agent in the spray mold release agent 78 is automatically sprayed toward the left mold 2 during the downward movement of the first horizontal plate 618, and the mold release agent in the spray mold release agent 78 is rotated 180 degrees during the upward movement of the first horizontal plate 618, so that the mold release agent in the spray mold release agent 78 is sprayed toward the right mold 3. Moreover, after the spray mold release agent 78 moves to a suitable position, the mold release agent is automatically stopped from being sprayed from the spray mold release agent 78, thereby facilitating the demolding of the molded rubber and plastic product.

[0068] Cooling liquid is placed inside the rectangular box 1. When the right rectangular sleeve 68 moves upward, the right mold 3 moves toward the left mold 2, so that the rotating optical axis 611 moves toward the direction close to the right clamping plate 62. The movement of the rotating optical axis 611 drives the U-shaped plate 910 to move toward the rectangular box 1. The movement of the longitudinal slot 911 drives the second horizontal plate 92 to move synchronously, and then pulls the sealing piston 94 to move through the bottom connecting plate 913. When the sealing piston 94 moves to the position of the side liquid inlet groove 912, the coolant inside the rectangular box 1 flows along the inside of the side liquid inlet groove 912 into the inside of the built-in box 93. In this process, the external gas flows into the inside of the built-in box 93 along the inside of the hard connecting pipe 95. After the injection molding is completed, the first horizontal plate 618 moves downward to make the right rectangular sleeve 68 move downward, thereby making the rotating optical axis 6 11 drives the U-shaped plate 910 to move in the direction away from the rectangular box body 1. The movement of the U-shaped plate 910 drives the sealing piston 94 to slide toward the inside of the built-in box 93 through the bottom connecting plate 913 and the second cross plate 92. When the sealing piston 94 passes the position of the side liquid inlet groove 912, the continued movement of the sealing piston 94 increases the air pressure inside the built-in box 93, so that the liquid inside the built-in box 93 flows along the inside of the hard connecting tube 95 and is sprayed into the inside of the embedded groove 99 along the inside of the nozzle 97, thereby achieving the effect of quickly cooling the left mold 2. It is beneficial that after the rubber and plastic product is injection-molded, when the right mold 3 moves in the direction away from the left mold 2, the coolant is automatically sprayed from the inside of the nozzle 97 to the inside of the left mold 2, thereby achieving the effect of quickly cooling the left mold 2, thereby further facilitating the removal of the rubber and plastic product after injection molding;

[0069] The U-shaped cover 98 limits the range of the coolant spraying, and the sprayed coolant can flow into the interior of the rectangular box 1 along the interior of the upper connecting groove 96, thereby facilitating the circulation of the coolant.
