The receiving plate has six sets of air grooves arranged in a ring. The main air seat has six sets of output ends and guide tube seats, and the bottom end of each set of guide tube seats is fixedly connected to the air grooves of the receiving plate. An adsorption tube communicating with the air grooves is fixedly connected to the bottom of the receiving plate, and a suction cup is fixedly installed at the bottom end of the adsorption tube. This material handling device for an injection molding machine, through the arrangement of the components on the receiving plate, can utilize the adsorption tubes and their bottom suction cups to adsorb onto different side walls of the workpiece. Then, according to requirements, the sub-air valves at the bottom ends of the guide tube seats on the top side of each adsorption tube can be opened, thereby achieving efficient adsorption and material handling of workpieces with different regular shapes as needed.

[0004] However, the above technical solution has the following shortcomings: when the device adsorbs the workpiece by means of suction cups, the distribution of the suction cups is relatively compact, resulting in poor stability when adsorbing the workpiece, which affects the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a material handling device for injection molding machines.

[0020] Example 1

[0021] like Figures 1-4 As shown in the figure, the material handling device for an injection molding machine proposed in this embodiment includes a base 1 and an adsorption device; a connecting seat 2 is provided above the base 1, a fixing column 3 is provided on the connecting seat 2, and a lifting plate 4 is provided on the fixing column 3.

[0022] The adsorption device includes six springs 5 ​​arranged in a ring array on the lifting plate 4, a mounting plate 6 located at the bottom of the springs 5, a main air seat 7 located on the mounting plate 6, a main frame 8 located on the mounting plate 6, five sub-supports 9 arranged in a ring array on the main frame 8, a first suction cup 10 located on the main frame 8, a second suction cup 11 located on the sub-supports 9, and multiple adsorption tubes 12 for connecting the main air seat 7 and the first suction cup 10 and the second suction cup 11 respectively.

[0023] In this embodiment, the structure design of a first suction cup 10 and five ring arrays distributed around the first suction cup 10 allows the first suction cup 10 and the second suction cup 11 to simultaneously adsorb the top center and five corner points of the workpiece's four sides during material handling. This not only ensures the gripping force on the workpiece but also improves the stability during the material handling process. When the first suction cup 10 and the second suction cup 11 are pressed and adhered to the surface of the workpiece, the main air seat 7 is activated, and the suction tube 12 causes the openings of the first suction cup 10 and the second suction cup 11 to generate suction force. Under the action of negative pressure, the workpiece is adsorbed, which fully ensures the stability of the injection molded workpiece handling process and has good practicality.

[0024] Example 2

[0025] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, a material handling device for an injection molding machine is proposed. Compared with the first embodiment, in this embodiment, a support seat 13 is provided on the base 1, a fixed frame 14 is provided on the support seat 13, a movable seat 17 is slidably connected to the fixed frame 14, a cylinder 18 is provided on the movable seat 17, the cylinder 18 and the connecting seat 2 are drivenly connected, a driving assembly is provided on the fixed frame 14, the driving assembly includes a motor 15 provided on the fixed frame 14 and a threaded rod 16 rotatably connected to the fixed frame 14, the movable seat 17 is threadedly connected to the threaded rod 16, a stabilizing slider 19 is provided on the connecting seat 2, and a groove is provided on the movable seat 17 for the stabilizing slider 19 to slide vertically.

[0026] The mounting plate 6 is provided with six guide rods 20 arranged in a ring array. The guide rods 20 pass through the lifting plate 4 and are slidably connected. Three limit blocks 21 are arranged in a ring array on the guide rods 20. The lifting plate 4 is provided with grooves for the limit blocks 21 to slide vertically. The connecting seat 2 is provided with two symmetrically distributed clearance grooves 22. The clearance grooves 22 are used to prevent the guide rods 20 from abutting against the connecting seat 2.

[0027] In this embodiment, when the adsorption device needs to be driven to pick up materials, the motor 15 is first started to drive the threaded rod 16 to rotate. The threaded rod 16 engages with the moving seat 17, causing the moving seat 17 to drive the cylinder 18 to move along the axial direction of the threaded rod 16 until the adsorption device is above the workpiece in the mold base. Then, the cylinder 18 is started to drive the connecting seat 2 to descend. The stabilizing slider 19 and the slide groove play a guiding and stabilizing role in the movement of the connecting seat 2. When the first suction cup 10 and the second suction cup 11 just come into contact with the workpiece, the mounting plate 6 will drive the main frame 8 and the sub-support 9 through the compression spring 5 to play a pressure buffering role, avoiding wear on the surface of the workpiece and ensuring the quality of material picking. In addition, the guide rod 20 can guide the extension and retraction of the spring 5 to prevent the spring 5 from bending or twisting. The limit block 21 can prevent the spring 5 from being in a stretched state when not picking up materials, thus extending the service life of the spring 5.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
