[0002] When producing plastic products, an injection molding machine is generally required, such as plastic products, safety helmets, household plastic handles, toilet brush handles, livestock feeding hoppers, etc. These plastic products need to be processed using an injection molding machine, and an injection molding machine manipulator is a machine specially equipped for injection molding production automation. It can imitate some functions of the upper limb of the human body and operate according to predetermined requirements. The manipulator can automatically unload the plastic products produced by the injection molding machine, greatly improving production efficiency.

[0003] Currently, the manipulator can usually move in any direction. For example, the manipulator for unloading an injection molding machine disclosed in the Chinese Patent Publication No. "CN220946519U" includes a main body mechanism and a driving mechanism. The driving mechanism is located above the main body mechanism. The main body mechanism includes a manipulator body, a grasping head, a positioning component, and rollers. The grasping head is movably installed above the manipulator body. The positioning component is located above the manipulator body. The rollers are fixedly installed at the lower end of the manipulator body.

[0004] Due to the large volume of the current manipulator, it occupies a very large space during transportation and movement, resulting in inconvenience during movement and transportation. The re-assembly after transportation brings many difficulties to users, and at the same time, it also wastes a lot of manpower and material resources. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art, such as large volume, occupying a very large space during transportation and movement, resulting in inconvenience during movement and transportation, and the re-assembly after transportation bringing many difficulties to users, etc., and to propose a manipulator for an injection molding machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a manipulator for an injection molding machine, including a base driven by a motor to rotate. At the top of the base, there is an inclined control arm. The bottom of the outer end of the control arm is hinged with a transverse driving unit. The bottom of the transverse driving unit is rotationally connected with a longitudinal driving unit through a connecting component. At the bottom of the longitudinal driving unit, there is a mechanical gripper. A clamping mechanism is arranged between the transverse driving unit and the control arm.

[0008] Further, the clamping mechanism includes a bump fixed to the top of the lateral driving unit. A through hole for fixation is provided on the surface of the bump. The top of the control arm is provided with an electric telescopic rod, and the telescopic part of the electric telescopic rod is inserted into the through hole.

[0009] Further, the connection assembly includes at least two vertical plates fixed to the bottom of the moving part of the lateral driving unit. A connecting seat is rotatably connected between the at least two vertical plates. The bottom of the connecting seat is fixedly connected to the longitudinal driving unit. A positioning mechanism is provided between the connecting seat and one of the vertical plates.

[0010] Further, the positioning mechanism includes a positioning ring fixed to the outer end of one of the vertical plates and at least two positioning holes spaced 90 degrees apart on the surface of the positioning ring. A sliding groove is provided on the surface of the connecting seat, and a moving block is slidably connected inside the sliding groove. A limiting column is fixed to the top of the moving block, and the limiting column is inserted into the positioning hole.

[0011] Further, a telescopic rod is provided between the moving block and the sliding groove, and a spring is sleeved on the surface of the telescopic rod. The two ends of the spring are respectively in contact with the sliding groove and the moving block. Guide blocks are fixed on both sides of the moving block, and positioning grooves are provided on both sides of the inner wall of the sliding groove. The guide blocks are slidably connected to the positioning grooves.

[0012] Further, a hook is hinged to the inner side of the control arm. A bump is fixed to the bottom of the lateral driving unit, and a hanging hole is provided on the surface of the bump. The hook is movably connected to the hanging hole.

[0013] The manipulator for an injection molding machine proposed by the present utility model has the beneficial effects that: through the electric telescopic rod, the entire lateral driving unit can be controlled to fold. After folding, it is connected to the control arm through the hook. The longitudinal driving unit can be folded through the limiting column. The combined action of the two can make the manipulator fold into a vertical state with a smaller occupied space, which is not only convenient for loading and transportation, but also does not require a large space when moving inside the factory building, and has good convenience.

At the top of the base 1, there is an inclined control arm 2, and at the bottom of the outer end of the control arm 2, a lateral drive unit 3 is hinged. The lateral drive unit 3 is driven by a drive motor to drive a screw to drive a moving part to reciprocate. The bottom of the lateral drive unit 3 is rotationally connected to a longitudinal drive unit 5 through a connection assembly 4. The longitudinal drive unit 5 drives the manipulator to move up and down through an electric telescopic member. At the bottom of the longitudinal drive unit 5, there is a mechanical gripper 6. A clamping mechanism 7 is provided between the lateral drive unit 3 and the control arm 2; the manipulator can be retracted through the electric telescopic rod 73 to control the entire lateral drive unit 3 to fold. After folding, it is connected to the control arm 2 through a hook 13. The longitudinal drive unit 5 can be folded through a limit post 85. The combined action of the two can make the manipulator fold into a vertical state with a smaller occupied space, which is not only convenient for loading and transportation, but also does not require a large space when moving inside the factory building, and has good convenience.

[0022] In this embodiment, the clamping mechanism 7 includes a convex block 71 fixed to the top of the lateral drive unit 3. On the surface of the convex block 71, there is a through hole 72 for fixing. At the top of the control arm 2, there is an electric telescopic rod 73, and the telescopic part of the electric telescopic rod 73 is inserted into the through hole 72. The entire lateral drive unit 3 can be controlled to fold by retracting the electric telescopic rod 73.

[0023] Furthermore, the connecting assembly 4 includes at least two vertical plates 41 fixed to the bottom of the moving part of the transverse driving unit 3, and a connecting seat 42 is rotatably connected between at least two of the vertical plates 41.

A positioning mechanism 8 is provided between the connecting seat 42 and a side vertical plate 41, and the longitudinal driving unit 5 at the bottom can be rotatably connected with the transverse driving unit 3 through the connecting seat 42 and the vertical plate 41.

[0024] Furthermore, the positioning mechanism 8 includes a positioning ring 81 fixed to the outer end of a vertical plate 41 on one side and at least two positioning holes 82 with an interval of ninety degrees are opened on the surface of the positioning ring 81. A sliding groove 83 is opened on the surface of the connecting seat 42, and a moving block 84 is slidably connected inside the sliding groove 83. A limiting column 85 is fixed on the top of the moving block 84, and the limiting column 85 is plugged into the positioning hole 82. The longitudinal drive unit 5 can be folded through the limiting column 85.
