[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides an injection molding production equipment, including an injection molding machine 1, a drive assembly 3 is provided on the rear side of the injection molding machine 1, the drive assembly 3 includes a mounting frame 33, and an air extraction assembly 4 is fixedly installed on the front end of the mounting frame 33. The air extraction assembly 4 includes an air pump 41. A connecting pipe 42 is fixedly connected to the output end of the air pump 41. A diverter pipe 43 is fixedly installed at the left end of the connecting pipe 42. A horizontal pipe 45 is fixedly installed at the bottom end of the diverter pipe 43. Nozzles 46 are fixedly installed at both the front and rear ends of the horizontal pipe 45. An air intake assembly 5 is movably connected to the bottom of the mounting bracket 33. The air intake assembly 5 includes a connector 55. A connecting frame 56 is fixedly installed on the outer wall of the connector 55. A movable shaft 44 is fixedly installed on the top of the connecting frame 56. A suction cup assembly 6 is provided below the connector 55.

[0020] By setting up the air pump 41, after the suction cup assembly 6 adsorbs the chip, the chip is taken upwards out of the injection cavity on the lower mold 14. At this time, the air pump 41 will draw air from the pressure valve assembly 8 and send the air into the connecting pipe 42. After the moving shaft 44 set in the connecting pipe 42 is pushed down, the connecting pipe 42 and the diversion pipe 43 are connected. At this time, the material residue in the injection cavity is blown out of the injection cavity, realizing automatic cleaning of the injection cavity. The operation is simple and convenient.

[0021] The injection molding machine 1 includes a worktable 11. A cylinder 12 is fixedly installed at the right end of the worktable 11. A slide plate 13 is fixedly sleeved at the output end of the cylinder 12. The slide plate 13 is slidably connected to the worktable 11. Two lower molds 14 are fixedly installed at the top of the slide plate 13. A mold closing injection structure 15 is provided above the lower molds 14.

[0022] There are two lower molds 14. After one lower mold 14 enters the lower part of the mold closing injection structure 15, the other lower mold 14 can be used for loading and unloading materials, thereby improving production efficiency. The cylinder 12 can drive the slide plate 13 to slide left and right, thereby driving the lower mold 14.

[0023] There are two injection molding machines 1, and a platform 2 is provided between the two injection molding machines 1.

[0024] The injection molding machine 1, the placement platform 2, and the drive assembly 3 are all fixedly installed on the ground. Both injection molding machines 1 are located in front of the drive assembly 3. The placement platform 2 is used to place the injection-molded chips.

[0025] The drive assembly 3 also includes a slide rail 31, which is located at the rear of the injection molding machine 1. The top of the slide rail 31 is connected to a drive component 32, and the mounting bracket 33 is connected to the front end of the drive component 32.

[0026] See Figure 2The mounting bracket 33 can move in three axes on the slide rail 31 by setting the driving component 32. This is existing technology and will not be described in detail here.

[0027] Among them, the connecting pipe 42 is fixed on the mounting bracket 33, and the diversion pipe 43 is located below the top of the moving shaft 44.

[0028] By making the connecting pipe 42 a rigid pipe, it can be ensured that the connecting pipe 42 will not fall off and will remain relatively fixed in position with the mounting bracket 33. After the air pump 41 supplies air into the connecting pipe 42, the gas can only enter the diversion pipe 43 after pushing the moving shaft 44 down, thereby ensuring that the moving shaft 44 is pushed down to connect the air intake assembly 5 and the suction cup assembly 6.

[0029] The air intake assembly 5 also includes a second connecting pipe 51, which is fixedly sleeved on the input end of the air pump 41. A three-way pipe 52 is fixedly installed at the bottom end of the second connecting pipe 51, a flexible hose 53 is fixedly installed at the bottom end of the three-way pipe 52, a fixed pipe 54 is fixedly installed at the bottom end of the flexible hose 53, a connector 55 is fixedly installed at the bottom end of the fixed pipe 54, and positioning shafts 57 are slidably connected to the left and right sides of the connecting bracket 56. The positioning shafts 57 are fixedly installed on the bottom end of the mounting bracket 33.

[0030] When the moving shaft 44 is pushed down, it can drive the connecting frame 56 down, thereby driving all the connectors 55 down, so that the connectors 55 are fitted onto the top of the suction cup body 63. At this time, the sealing ring 66 at the bottom of the limiting ring 65 and the sealing ring 66 at the top of the suction cup body 63 come into contact with each other, sealing the connectors 55 and the suction cup body 63. The positioning shaft 57 positions and guides the movement of the connecting frame 56. At this time, the connectors 55 and the suction cup body 63 are connected, and air is introduced through the suction cup body 63. Since the chips are attached to the bottom of the suction cup body 63, the chips can be attracted.

[0031] The mounting bracket 33 has a connection hole 61 at its bottom end. A swing ring 62 is rotatably connected to the inner cavity of the connection hole 61. A suction cup body 63 is placed in the inner cavity of the swing ring 62. A support ring 64 is fixedly installed on the outer wall of the suction cup body 63. The support ring 64 is located above the swing ring 62. A limit ring 65 is fixedly installed in the inner cavity of the connector 55. A sealing ring 66 is fixedly installed at the bottom end of the limit ring 65 and the top end of the suction cup body 63.

[0032] When the connector 55 is separated from the suction cup body 63, the suction cup body 63 can be tilted in the vertical direction by rotating it. At this time, the top of the suction cup body 63 is away from the bottom of the connector 55, and the suction cup body 63 can be directly tilted to remove the swing ring 62, so that the suction cup body 63 can be quickly replaced and maintained. The operation is simple and convenient.

[0033] Magnets 9 are fixedly installed on both the bottom of the limiting ring 65 and the top of the suction cup body 63, with the magnetic poles of two adjacent magnets 9 being opposite.

[0034] See Figure 8 The bottom of the magnet 9 on the left side of the bottom of the limiting ring 65 is the N pole, and the bottom of the magnet 9 on the right side of the bottom of the limiting ring 65 is the S pole. The top of the magnet 9 on the left side of the top of the suction cup body 63 is the S pole, and the top of the magnet 9 on the right side of the top of the suction cup body 63 is the N pole. By setting the magnet 9, when the limiting ring 65 is separated from the suction cup body 63, the suction cup body 63 can be kept below the limiting ring 65 by the influence of magnetic force. And when the connector 55 moves down and fits onto the suction cup body 63, it can be ensured that the suction cup body 63 is aligned with the connector 55.

[0035] Among them, a spring 7 is fixedly installed at the top of the mounting bracket 33, and the top of the spring 7 is fixedly installed at the bottom of the connecting bracket 56.

[0036] By setting spring 7, after the connecting frame 56 loses its downward pressure, the elasticity of spring 7 can push the connecting frame 56 back to its original position.

[0037] The three-way pipe 52 is equipped with a pressure valve assembly 8, which includes a fixing plate 81. The fixing plate 81 is fixedly installed on the left end of the three-way pipe 52. A telescopic rod 82 and a second spring 83 are fixedly installed on the left end of the fixing plate 81. A sealing ring 84 is fixedly installed on the left end of the telescopic rod 82 and the second spring 83. A sealing plate 85 is provided on the left side of the sealing ring 84. The sealing plate 85 is fixedly installed on the inner wall of the left end of the three-way pipe 52.

[0038] The elasticity of spring 83 provides a force to the left for the closing ring 84, thereby closing the left end of the three-way tube 52. Therefore, air will preferentially enter from the bottom end of the three-way tube 52, that is, from the suction cup body 63. After the suction cup body 63 is closed, the suction force generated by the air pump 41 pulls the closing ring 84 to the right, thereby opening the left end of the three-way tube 52 for air intake. Working principle and usage process of this invention: A feeding machine is also provided on the right side of the device, which places the circular metal sheet on the right side of the injection molding machine 1; In the first injection, the right-side drive component 32 drives the mounting bracket 33 to move to the right and grabs the circular metal piece through the suction cup assembly 6. Then, the circular metal piece is transported to the left and placed into one of the lower molds 14 in the right-side injection molding machine 1. Subsequently, the mold closing injection structure 15 drives the mold closing to perform injection molding to form a semi-finished product. Subsequently, the cylinder 12 on the right injection molding machine 1 pushes the lower mold 14 away from below the mold closing injection structure 15, so that the other lower mold 14 is located below the mold closing injection structure 15, and the robot on the right continues to perform the loading operation. In the second injection, the drive unit 32 on the left side drives the semi-finished product to be taken out from the lower mold 14 on the right side and then placed on one of the lower molds 14 on the left side of the injection molding machine 1. Then the mold closing injection structure 15 on the left side performs mold closing injection to form chips. Subsequently, the cylinder 12 on the left pushes the lower mold 14 to send out the mold closing injection structure 15, and the drive component 32 on the left drives the suction cup assembly 6 to take the chips out of the lower mold 14 and place them on the placement platform 2. When the suction cup assembly 6 picks up chips and semi-finished products, the drive unit 32 first sends the suction cup body 63 above the chips or semi-finished products and into contact with them. At this time, the connector 55 is separated from the suction cup body 63. The air pump 41 is started, and the air pump 41 draws outside air through the connector 55 into the hose 53, the three-way pipe 52 and the second connecting pipe 51. Then, the air pump 41 delivers the air to the first connecting pipe 42 and pushes down the moving shaft 44 to connect the diversion pipe 43 with the first connecting pipe 42. During this process, the moving shaft 44 drives the connecting frame 56 and the connecting... The connector 55 and the fixing tube 54 move down together, so that the connector 55 is inserted into the suction cup body 63, connecting the connector 55 and the suction cup body 63. At this time, the air pump 41 will pick up the chips or semi-finished products, and then drive the chips or semi-finished products to move up and away from the injection cavity a short distance. At this time, since the bottom end of the three-way pipe 52 is closed, the suction force generated by the air pump 41 will open the pressure valve assembly 8, and then open the left side of the three-way pipe 52. At this time, air enters from the left end of the three-way pipe 52. After the gas enters the diversion pipe 43, it is sprayed into the injection cavity through the horizontal pipe 45 and the nozzle 46 to clean the residue. When the air pump 41 is not started, the entire device does not take in air. At this time, the spring 7 loses pressure and pushes the connecting bracket 56 back to its original position under the action of elasticity, thereby causing the connector 55 to leave the suction cup body 63. If it is necessary to replace or maintain the suction cup body 63, simply tilt the suction cup body 63 and remove it from the swing ring 62.
