Description

Technical Field

[0001] The invention belongs to the technical field of taking out parts from injection molds, and in particular relates to a device for taking out parts of air conditioner plastic parts after injection molding. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. When the injection molding machine is working, in order to improve the efficiency and safety of taking out parts, a robot is often used instead of manual taking out. The robot can automatically take out the product very accurately, thereby increasing production capacity, reducing the defective rate of product costs, and saving manpower and material resources.

[0003] A Chinese patent with the authorization publication number CN220180058U discloses a pickup device for an injection molding machine, comprising a support frame, wherein the inner wall of the support frame is respectively fixedly connected with a vertical guide rod and a horizontal guide rod, the surface of the vertical guide rod is slidably connected with a mounting column, a suction cup is fixedly installed at the bottom end of the mounting column, a clamping mechanism is provided on the horizontal guide rod, a driving shaft is slidably connected with the inner wall of the mounting column, and a conversion mechanism is provided on the driving shaft. The pickup device for the injection molding machine has the functions of clamping and adsorbing the pickup by providing a clamping mechanism and a suction cup, and the driving shaft can be matched with the clamping mechanism or the mounting column by providing a conversion mechanism, so that different pickup methods can be flexibly selected according to the type of injection molded product, thereby improving the scope of application of the device, and different pickup methods can also be realized through the same power source, thereby reducing costs and further improving the applicability of the device.

[0004] Existing removal devices usually use a vacuum system to generate suction to firmly fix the injection molded part on the suction cup, and then pull the suction cup to make the injection molded part as a whole detach from the mold. Some equipment will also add an ejection mechanism to push the injection molded part down from the mold, and then use the vacuum system to generate suction to remove the part. However, some injection molding materials themselves have high adhesion, or are easy to adhere to the mold under specific process conditions. At the same time, if the mold temperature is too high or the cooling is uneven, the injection molded part may form excessive adhesion on the mold surface. All of these will make it difficult for the injection molded part to detach from the mold and cause damage when the existing equipment is removing the part. Summary of the invention

[0005] The purpose of the present invention is to provide a device for removing air conditioner plastic parts after injection molding, aiming to solve the problem in the prior art that injection molded parts are easily adhered to the mold, resulting in difficulty in removing the injection molded parts from the mold and causing damage.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for removing parts after injection molding of air-conditioning plastic parts, comprising an injection molding device, a driving mechanism arranged on the injection molding device, and a removal mechanism arranged in the air above the injection molding device, wherein the driving mechanism controls the removal mechanism to remove parts.

[0007] The taking-out mechanism includes two symmetrical mounting frames, an adjusting plate and a plurality of suction cup mechanisms, a plurality of connecting plates are connected between the two mounting frames, and the plurality of suction cup mechanisms are respectively slidably sleeved on the plurality of connecting plates vertically, and the outer wall of the suction cup mechanism is slidably sleeved with a clamping plate located above the connecting plate, and elastic buffer members sleeved on the outer wall of the suction cup mechanism are provided above the clamping plate and below the connecting plate, a groove is provided on the top of the connecting plate, and cams for lifting the clamping plate are provided on both sides of the inner wall of the groove, and a gear is fixedly installed after the rotating shaft of the cam rotates and passes through the connecting plate, and adjusting rods are provided on the plurality of connecting plates, and racks for meshing with the gears are provided on the side walls of the adjusting rods, and the height of the racks on the adjusting rods gradually increases with approaching the center of the mounting frame, and the adjusting plate is arranged above the connecting plate and fixedly connected to the top end of the adjusting rod, and push rods are symmetrically provided at both ends of the adjusting plate for pushing against the mold when taking out the parts.

[0008] The effect is that the suction cup mechanism can be controlled to first drive the injection molded part to gradually separate from the mold in the order from the edge to the center, thereby avoiding the situation in which the injection molded part is directly separated from the mold as a whole and thus being damaged when the injection molded part is removed.

[0009] A plurality of U-shaped plates evenly distributed along the length direction of the mounting frames are installed between the tops of the two mounting frames, the openings of the U-shaped plates face downward, and an elastic reset member is fixedly connected between the top of the adjustment plate and the U-shaped plate, and the elastic reset member is a spring.

[0010] The effect is that the adjustment plate can be fixed so that the movement of the adjustment plate and the adjustment rod is not affected, and both can move synchronously with the mounting frame, thereby ensuring the normal operation of the pickup device.

[0011] The suction cup mechanism includes a connecting tube that is vertically slidably sleeved on the connecting plate, and a vacuum suction cup is fixedly connected to the bottom end of the connecting tube. There are multiple connecting tubes and they are evenly distributed along the length direction of the connecting plate. A vacuum suction pipe is connected between the tops of the multiple connecting tubes. There are multiple adjusting rods on the connecting plate. As the height of the rack on the adjusting rod gradually increases toward the center of the connecting plate, limiting parts are fixedly installed on the top and bottom of the outer wall of the connecting tube for connecting an elastic buffer, which is a spring.

[0012] There are two symmetrical cams installed on one side of the inner wall of the groove, and the number of adjustment rods is the same as the cams. The two adjustment rods are located on the sides of the two gears that are away from each other, and are used to drive the two gears to rotate synchronously in opposite directions.

[0013] The effect is that the device can be demoulded from the four corners of the injection molded part first when gradually leaving the mold in the order from the edge to the center, thereby avoiding damage to the middle part of the edge of the injection molded part when demoulding at the edge.

[0014] The removal mechanism also includes a lifting plate that is slid up and down on the driving mechanism. Extensions are provided at both ends of the bottom of the lifting plate. Protrusions are provided in the top ends of the two mounting frames. The top ends of the two protrusions are hinged to the two extensions of the bottom of the lifting plate through rotating shafts. A driving device is provided on one side of the extension for driving the mounting frame and its protrusion to rotate with the rotating shaft as the axis.

[0015] The effect is that the picking-up mechanism can be controlled to descend and rotate from a horizontal state to a vertical state at the same time, so that the vacuum suction cup on the picking-up mechanism can face the injection molded part, thereby completing the picking-up work after the injection molded part is formed.

[0016] The driving mechanism includes a support frame, a slider and a support plate. The support frame is an L-shaped rod and is installed on one side of the injection molding device. Its cross bar is located above the injection molding device. The slider is slidably sleeved on the cross bar of the support frame. The support plate is perpendicular to the support frame in the horizontal direction and is slidably sleeved on the top of the slider. The lifting plate is vertically arranged at one end of the support plate. Both sides of the lifting plate are provided with telescopic parts fixedly installed at one end of the support plate, and the telescopic tube of the telescopic part is fixedly connected to the top of the lifting plate.

[0017] The crossbar and slider of the support frame are both equipped with driving parts for driving the slider and the support plate to move, wherein the slider moves along the crossbar direction of the support frame, and the support plate moves on the slider along the length direction of the support plate.

[0018] The effect is that it can automatically control the descent, picking up, rising and transfer processes of the picking mechanism, so that the device can smoothly complete the demoulding, picking up and unloading of injection molded parts, ensuring the normal progress of the picking work and improving work efficiency.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The suction cup mechanism can be controlled to first separate from the mold at the four corners of the injection molded part. As the adjusting plate and the adjusting rod continue to move toward the mounting frame, the racks on the remaining adjusting rods mesh with the gears in turn, and the suction cup mechanism is controlled to drive the injection molded part to gradually separate from the mold in the order from the edge to the center, thereby avoiding the situation in which the injection molded part is directly separated from the mold as a whole at the same time, causing damage to the injection molded part when it is removed.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 The present invention provides the following technical solutions: a device for taking out plastic parts of an air conditioner after injection molding, comprising an injection molding device 1, a taking-out mechanism 2, a driving mechanism 3 and a receiving box 4, wherein the taking-out mechanism 2 and the driving mechanism 3 are arranged above the injection molding device 1, and the receiving box 4 is arranged on one side of the injection molding device 1, and the driving mechanism 3 drives the taking-out mechanism 2 to take out the plastic parts after injection molding from the mold and put them into the receiving box 4.

[0032] refer to Figure 3-Figure 7 As shown, the removal mechanism 2 includes two mounting frames 22 which are arranged above the mold of the injection molding device 1 and are symmetrical to each other, an adjustment plate 25, a plurality of suction cup mechanisms and an elastic buffer 29. A plurality of connecting plates 221 for installing the suction cup mechanisms are connected between the two mounting frames 22. A groove 222 is provided on the top of the connecting plate 221. The plurality of suction cup mechanisms are respectively vertically slidably penetrated and installed on the plurality of connecting plates 221. A clamping plate 281 which is slidably sleeved on the outer wall of the suction cup mechanism is provided above the groove 222. The elastic buffer 29 is provided above the clamping plate 281 and below the connecting plate 221 and sleeved on the outer wall of the suction cup mechanism. Cams 223 for lifting the clamping plate 281 are rotatably installed on both sides of the inner wall of the groove 222. The cam 223 is provided with a plurality of After the rotating shaft rotates and passes through the connecting plate 221, a gear 224 is fixedly installed thereon. Adjusting rods 26 are provided on the side walls of the multiple connecting plates 221. A rack 261 for meshing with the gear 224 is provided on the side walls of the adjusting rods 26. As the adjusting rods 26 approach the center of the mounting frame 22, the height of the rack 261 on the adjusting rods 26 gradually increases. The adjusting plate 25 is arranged in the air above the connecting plate 221. The top of the adjusting rod 26 is fixedly connected to the adjusting plate 25. Push rods 251 are symmetrically arranged at both ends of the adjusting plate 25 for supporting the mold when taking out the parts. A U-shaped plate 24 with an opening facing downward is installed between the tops of the two mounting frames 22. An elastic reset member 252 is connected between the top of the adjusting plate 25 and the U-shaped plate 24. The elastic reset member 252 is a spring.

[0033] When the injection molded part is taken out, the mounting frame 22 moves toward the injection molded part, so that the ejector rod 251 installed on the adjusting plate 25 is pressed against the mold. As the mounting frame 22 continues to move, the U-shaped plate 24 and the adjusting plate 25 begin to approach each other and compress the elastic reset member 252, and the vacuum suction cup 282 contacts the injection molded part. The vacuum suction cup 282 is adsorbed on the injection molded part. At this time, the support plate 33 drives the mounting frame 22 to move away from the injection molded part. The mounting frame 22 drives the suction cup mechanism to rise through the elastic buffer 29, which generates a pulling force on the injection molded part, causing it to have a tendency to break away from the injection mold. The elastic reset member 252 begins to reset and release the compression force as the mounting frame 22 drives the U-shaped plate 24 to move. At this time, the adjusting plate 25 and the adjusting rod 26 are in the elastic The reset member 252 is moved closer to the mounting frame 22 by the elastic force of the reset member 252. Since the height of the rack 261 on the adjusting rod 26 gradually increases as it approaches the center of the mounting frame 22 and the center of the connecting plate 221, as the adjusting rod 26 moves toward the mounting frame 22, the racks 261 on the adjusting rod 26 located at both ends of the mounting frame 22 and the connecting plate 221 first mesh with the gear 224 and drive the gear 224 to rotate. At this time, the cam 223 rotates synchronously with the gear 224 and lifts up the card plate 281. At this time, the card plate 281 exerts pressure on the elastic buffer 29 again, so that the force of the elastic buffer 29 on the suction cup mechanism is further increased, thereby driving the four corners of the injection molded part to begin to separate from the mold through the suction cup mechanism.

[0034] The suction cup mechanism includes a connecting tube 28 vertically slidably sleeved on the connecting plate 221, with a vacuum suction cup 282 fixedly connected to the bottom end thereof. There are multiple connecting tubes 28 and they are evenly distributed along the length direction of the connecting plate 221. A vacuum suction pipe 27 is connected between the tops of the multiple connecting tubes 28. There are multiple adjusting rods 26 on the connecting plate 221. As the height of the rack 261 on the adjusting rod 26 gradually increases as it approaches the center of the connecting plate 221.

[0035] The taking-out mechanism 2 also includes a lifting plate 21 which is slidably arranged up and down on the driving mechanism 3. Both ends of the bottom of the lifting plate 21 are provided with extensions. The top ends of the two mounting frames 22 are provided with protrusions 225. The top ends of the two protrusions 225 are respectively hinged to the two extensions of the bottom of the lifting plate 21 through rotating shafts. One side of the extension is provided with a driving device 23 for driving the mounting frame 22 and its protrusion 225 to rotate around the rotating shaft. The driving device 23 is a servo motor.

[0036] refer to Figure 6 As shown, there are two cams 223 and gears 224 installed on one side of the inner wall of the groove 222. The number of the adjusting rods 26 is the same as the cams 223, and they are located between the two gears 224 or on the side where the two gears 224 are away from each other, so as to drive the two gears 224 to rotate synchronously in opposite directions.

[0037] refer to Figure 1 and Figure 2 As shown, the driving mechanism 3 includes a support frame 31, a slider 32 and a support plate 33. The support frame 31 is an L-shaped rod and is installed on one side of the injection molding device 1, and its cross bar is located above the injection molding device 1. The slider 32 is slidably sleeved on the cross bar of the support frame 31, and the driving member drives the slider 32 to move along the cross bar of the support frame 31. The support plate 33 is perpendicular to the support frame 31 in the horizontal direction and is slidably sleeved on the top of the slider 32. The driving member drives the support plate 33 to slide on the slider 32 along the length direction of the support plate 33. The lifting plate 21 is vertically downwardly arranged at one end of the support plate 33. Both sides of the lifting plate 21 are provided with a telescopic member 34 fixedly installed at one end of the support plate 33. The telescopic tube of the telescopic member 34 is fixedly connected to the top of the lifting plate 21. The telescopic member 34 is an electric telescopic rod in this embodiment and a cylinder in other embodiments.

[0038] The driving member drives the slider 32 to move along the cross bar of the support frame 31, thereby driving the taking-out mechanism 2 to move left and right, and adjusting the position of the taking-out mechanism 2 in the left and right direction. The driving member drives the support plate 33 to slide on the slider 32 along the length direction of the support plate 33, thereby driving the taking-out mechanism 2 to move forward and backward, and adjusting the position of the taking-out mechanism 2 in the front and back directions. By adjusting the taking-out mechanism 2 in the front and back and left and right directions, it is located directly above the injection mold of the injection molded part, and thus the injection molded part can be smoothly taken out. After the taking-out is completed, the taking-out mechanism 2 is controlled by the driving member to move in the front and back and left and right directions, so that it moves to the top of the receiving box 4 to complete the unloading.

[0039] The implementation principle of the embodiment of the present invention is as follows: when the injection molded part is to be taken out, the telescopic member 34 is started to drive the lifting plate 21 and the mounting frame 22 to descend, and at the same time, the driving device 23 is started to drive the mounting frame 22 to rotate with the protruding portion 225 of the mounting frame 22 and the hinged shaft of the extension of the lifting plate 21 as the axis, so that the taking-out mechanism 2 is rotated from a horizontal state to a vertical state. When the lifting plate 21 drives the mounting frame 22 to descend to the same level as the injection molded part, the lifting plate 21 stops descending, and the driving member drives the support plate 33 to slide on the slider 32 along the length direction of the support plate 33, so that the mounting frame 22 moves toward the injection molded part, so that the ejector rod 251 installed on the adjustment plate 25 is pressed tightly against the mold. As the mounting frame 22 continues to move, the U-shaped plate 24 and the adjustment plate 25 begin to approach each other, the elastic reset member 252 between the U-shaped plate 24 and the adjustment plate 25 is compressed, the vacuum suction cup 282 contacts the injection molded part, and the suction cup mechanism is controlled to work so that the vacuum suction cup 282 is adsorbed on the injection molded part. The driving member drives the support plate 33 to drive the mounting frame 22 to move away from the injection molded part. At this time, the mounting frame 22 and the card plate 281 begin to compress the elastic buffer 29 installed on the card plate 281, and the mounting frame 22 begins to stretch the elastic buffer 29 installed on the mounting frame 22, and drives the suction cup mechanism to rise through the elastic buffer 29, so as to generate a pulling force on the injection molded part, so that it has a tendency to break away from the injection mold. As the elastic reset member 252 is in a compressed state, as the mounting frame 22 drives the U-shaped plate 24 to move, the elastic reset member 252 begins to reset and release the compression force. At this time, the adjusting plate 25 and the adjusting rod 26 are close to each other with the mounting frame 22 under the elastic force of the elastic reset member 252. As the height of the rack 261 on the adjusting rod 26 gradually increases as it approaches the center of the mounting frame 22 and the center of the connecting plate 221, as the adjusting rod 26 moves toward the mounting frame 22, the racks 261 on the adjusting rod 26 located at both ends of the mounting frame 22 and the connecting plate 221 first mesh with the gear 224 and drive the gear 224 to rotate. At this time, the cam 223 is synchronized with the gear 224. Rotate and lift the card plate 281. At this time, the card plate 281 generates pressure on the elastic buffer 29 again, so that the force of the elastic buffer 29 on the suction cup mechanism is further increased, thereby driving the four corners of the injection molded part to begin to separate from the mold through the suction cup mechanism. As the adjustment plate 25 and the adjustment rod 26 continue to move toward the mounting frame 22, the racks 261 on the remaining adjustment rods 26 are meshed with the gears 224 in turn, and control the suction cup mechanism to drive the injection molded part to gradually separate from the mold, so that the device can drive the injection molded part to gradually separate from the mold in the order from the edge to the center, avoiding the situation where the injection molded part is directly separated from the mold as a whole at the same time, causing the injection molded part to be damaged when it is removed.

[0040] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
