Description

Technical Field

[0001] This utility model relates to the technical field of automated injection molding equipment, and in particular to an automatic material handling device for injection molding machines. Background Technology

[0002] Injection molding equipment is the core equipment in the field of plastics processing. It is mainly used to inject thermoplastic or thermosetting plastics into the mold cavity through heating and pressurization, and finally form various plastic products.

[0003] In an automated injection molding machine in the industry, a typical work cycle can be divided into the following steps: feeding and melting, injection and holding pressure, cooling and shaping, mold opening and ejection, and material handling and turnover. Specifically, plastic granules are fed into the heating cylinder through the hopper and melted by the rotation of the screw or the advancement of the plunger; the molten plastic is injected into the mold cavity at high speed under high pressure, and then pressure is held to compensate for shrinkage; the mold cools to solidify the plastic, and the time depends on the material and the thickness of the product; the mold is separated, the ejection system pushes out the finished product, and the worker takes out the plastic part for turnover before entering the next injection molding process cycle.

[0004] Based on this, Chinese patent CN103465435B discloses an injection molding machine, which includes an injection system, a hydraulic transmission system, an electrical control system, and a heating and cooling system. The injection system has two or more pressure-holding stations around the injection station. Each pressure-holding station includes a press, an upper pressure plate, a mold, a lower pressure plate, a guide rod, and a hydraulic cylinder. The press is located above the pressure-holding station and applies pressure to the top surface of the mold through the upper pressure plate. The bottom surface of the mold is fixed to the guide rod, which is equipped with pulleys or sliding plates that can slide on the lower pressure plate. The hydraulic cylinder is located below the lower pressure plate and applies pressure to the bottom surface of the mold through the lower pressure plate. By pushing and pulling the guide rod, the mold is pushed into or pulled out of the injection station. This injection molding machine disclosed in this patent does not affect the injection pressure during pressure holding and cooling, achieving continuous injection pressure and pressure holding / cooling, thus improving production efficiency.

[0005] However, the aforementioned injection molding equipment still suffers from poor material handling efficiency. Specifically, in automated injection molding processes, after the front and rear molds separate and the molded part is ejected by the injection molding machine's ejection system, manual material handling and placement into a turnover box are typically required. The usual procedure is as follows: the hydraulic / pneumatic ejection mechanism in the injection molding machine advances the ejector plate forward, and the ejector pins eject the molded part at a speed of 0.5-2 m / s; the operator wears high-temperature resistant gloves and uses non-metallic tweezers to grasp the edges of the workpiece to avoid scratching its surface; afterwards, a quick visual inspection is performed to check for residual burrs at the ejector pin location, and if necessary, an air gun is used to remove debris. Current methods of handling molded parts are time-consuming and labor-intensive, and the direct contact between operators and high-temperature molds or moving mechanical parts increases the risk of workplace injuries.

[0027] Please refer to the following: Figures 1 to 3 This utility model discloses an automatic material handling device for injection molding machines, comprising: a support frame 1, a vertical frame 2, a horizontal drive module 3, a vertical drive module 4, an adsorption and material handling module 5, a CCD camera module 6, and a material guiding and turnover module 7. The vertical frame 2 is mounted on the support frame 1, the horizontal drive module 3 is mounted on the side of the vertical frame 2, and the vertical drive module 4 is mounted on the side of the horizontal drive module 3. The horizontal drive module 3 and the vertical drive module 4 are drivenly connected. The adsorption and material handling module 5 is mounted below the vertical drive module 4, and the vertical drive module 4 is drivenly connected to the adsorption and material handling module 5. The CCD camera module 6 is mounted adjacent to the horizontal drive module 3 on the vertical frame 2, and the material guiding and turnover module 7 is mounted below the vertical frame 2 on the support frame 1.

[0028] Specifically, when the automatic material handling device for an injection molding machine is in operation, the external injection molding machine is adjacent to the side of the support frame 1. When one injection molding process is completed, the external injection mold opens. At this time, the CCD camera module 6 marks the position of the injection molded part in the injection mold and takes pictures of the appearance of the injection molded part, which are then uploaded. The external industrial control computer judges the appearance of the injection molded part and confirms that the appearance of the injection molded part is qualified. Then, the horizontal drive module 3 drives the vertical drive module 4 to carry the adsorption material handling module 5 to the top of the opened injection mold. After that, the vertical drive module 4... The direct drive module 4 drives the adsorption and material-grabbing module 5 downward to a preset height so that the adsorption and material-grabbing module 5 can abut against and pick up the injection part from the injection mold. Then, the vertical drive module 4 drives the adsorption and material-grabbing module 5 upward to reset, and then the horizontal drive module 3 drives the vertical drive module 4 to carry the adsorption and material-grabbing module 5 to the material-guiding and turnover module 7. Finally, the vertical drive module 4 drives the adsorption and material-grabbing module 5 downward to a preset height, and the adsorption and material-grabbing module 5 releases the injection part into the material-guiding and turnover module 7. Thus, one automatic material-grabbing and turnover process is completed. It can be seen that the automatic material-grabbing device for injection molding machines of this utility model can replace the manual process of picking up materials from the injection mold in the traditional injection molding process. Through the automated material-grabbing and turnover module design, the material-grabbing and turnover efficiency of the injection molding machine can be improved.

[0029] Furthermore, the lateral drive module 3 includes a rodless cylinder bracket 301, a rodless cylinder 302, a rodless cylinder guide rail 303, and a piston slider 304; the rodless cylinder bracket 301 is disposed on the side of the upright 2, and the rodless cylinder 302 is disposed within the rodless cylinder bracket 301; the rodless cylinder guide rail 303 is disposed adjacent to the rodless cylinder 302 within the rodless cylinder bracket 301; the piston slider 304 is movably disposed on the rodless cylinder guide rail 303, and the rodless cylinder 302 is drivenly connected to the piston slider 304.

[0030] Furthermore, the vertical drive module 4 includes an L-shaped connecting block 401, a vertical drive cylinder 402, a vertical telescopic piston rod 403, a vertical guide rod 404, and a vertical connecting block 405. The L-shaped connecting block 401 is connected to the side of the piston slider 304, the vertical drive cylinder 402 is disposed within the L-shaped connecting block 401, and the vertical drive cylinder 402 is drivenly connected to the vertical telescopic piston rod 403. The two vertical guide rods 404 are movably disposed on both sides of the vertical drive cylinder 402 on the L-shaped connecting block 401. The vertical connecting block 405 is connected to the end of the vertical telescopic piston rod 403, and each vertical guide rod 404 is connected to the vertical connecting block 405.

[0031] Furthermore, the adsorption and material handling module 5 has an adsorption frame 501 and a plurality of suction cup structures 502; the adsorption frame 501 is connected to the vertical connecting block 405 below, and the plurality of suction cup structures 502 are evenly distributed in the adsorption frame 501.

[0032] Specifically, in a single process of adsorbing or releasing a workpiece, after the rodless cylinder 302 is activated, it can drive the piston slider 304 to move back and forth along the limit of the rodless cylinder guide rail 303; then, the piston slider 304 drives the L-shaped connecting block 401 so that the vertical drive module 4 and the adsorption and material handling module 5 located on the side of the L-shaped connecting block 401 are positioned above the material to be picked up; then, the vertical drive cylinder 402 drives the vertical telescopic piston rod 403 to extend or shorten so that the vertical connecting block 405 can move down or up to a preset height position, and the vertical guide rod 404 can make the movement of the vertical connecting block 405 more stable when it moves down or up; thereafter, the suction cup structure 502 provided in the adsorption frame 501 located below the vertical connecting block 405 can adsorb or release the workpiece.

[0033] Furthermore, the CCD camera module 6 includes a hanger 601, an industrial camera 602, and a light source 603; the hanger 601 is disposed adjacent to the horizontal drive module 3 on the stand 2, the industrial camera 602 is connected to the two hangers 601, and the light source 603 is disposed below the industrial camera 602.

[0035] Specifically, the turnover box 702 has a box body 702a, a handle 702b, and a wedge-shaped groove 702c; each of the two sides of the box body 702a is provided with a handle 702b, and the wedge-shaped groove 702c is disposed on the box body 702a, and the wedge-shaped groove 702c is movably engaged with the end of the sliding chute 701.

[0036] Specifically, when the horizontal drive module 3 drives the vertical drive module 4 to bring the material-carrying adsorption module 5 above the sliding chute 701, the vertical drive module 4 drives the adsorption module 5 downward to a preset height. Then, the suction cup structure 502 in the adsorption module 5 releases the workpiece material, causing the workpiece to fall onto the sliding chute 701 and down along the sliding chute 701 into the box body 702a in the turnover box 702. The wedge-shaped slot 702c provided in the turnover box 702 allows the box body 702a to be movably embedded in the lower end of the sliding chute 701; the user can quickly rotate the turnover box 702 containing the workpiece by dragging the handle 702b.
