[0029] Refer to Figures 1-3 As shown, an injection molding die part picking and placing manipulator of the present utility model includes: a base 1 connected to an ABB robot through a locking fixing plate 100; a support frame 2 vertically arranged on the base 1; a part loading mechanism 3 which is arranged at the middle position of the support frame 2 through a support plate 4 and is used for clamping parts on a loading table and placing them inside an injection molding die; the part loading mechanism 3 includes a support seat 31, a first slide cylinder 32, a second slide cylinder 33, a first clamping mechanism 34 and a second clamping mechanism 35, the support seat 31 is vertically arranged on the support plate 4, the first slide cylinder 32 and the second slide cylinder 33 are respectively arranged on both sides of the support seat 31; the first slide cylinder 32 is connected to the first clamping mechanism 34 through a first fixing seat 36, and the second slide cylinder 33 is connected to the second clamping mechanism 35 through a second fixing seat 37; the first slide cylinder 32 and the second slide cylinder 33 respectively control the first clamping mechanism 34 and the second clamping mechanism 35 to move in opposite directions.

[0030] Such as Figure 5 And 6As shown, it further includes an injection molding finished product taking-out mechanism 5. The injection molding finished product taking-out mechanism 5 is arranged at the end of the support frame 2 and is used to take out the finished products molded in the injection mold. The injection molding finished product taking-out mechanism 5 includes a third slide table cylinder 51, a third fixed seat 52, a first finger cylinder 53 and a first clamping jaw 54 that cooperates with the first finger cylinder 53. The third slide table cylinder 51 is fixed on the support frame 2 through a mounting seat 55, and the first finger cylinder 53 is connected to the third slide table cylinder 51. In this embodiment, there are four injection molding finished product taking-out mechanisms 5, which can simultaneously take out four injection molding finished products in the injection mold, and the taking-out efficiency is high.

[0031] By setting the injection molding finished product taking-out mechanism 5, the third slide table cylinder 51 is used to control the first finger cylinder 53 to approach the injection molded product, and then the first clamping jaw 54 is used to take out the already molded injection molded product, effectively solving the problem that the injection molded product cannot be taken out manually due to its high temperature when taking out the injection molded product, and greatly improving the taking-out efficiency of the product.

[0032] As Figure 3 shown, the first clamping mechanism 34 includes a second finger cylinder 341 and a second clamping jaw 342 that cooperates with the second finger cylinder 341. As Figure 4 shown, the first slide table cylinder 32 is connected to the second finger cylinder 341 through a first fixed seat 36; the second clamping mechanism 35 includes a third finger cylinder 351 and a third clamping jaw 352 that cooperates with the third finger cylinder 351; the second slide table cylinder 33 is connected to the third finger cylinder 351 through a second fixed seat 37. In this embodiment, there are four first clamping mechanisms 34 and four second clamping mechanisms 35, which are symmetrically arranged on both sides of the support plate 4 and can simultaneously clamp and load multiple different types of metal parts, greatly improving the working efficiency.

[0033] In this embodiment, a number of positioning columns 38 are provided on one side of the support plate 4 facing the second clamping mechanism 35. The positioning columns 38 are used for the positioning of the support plate 4 and the injection mold, thereby realizing the preliminary positioning of the entire part loading mechanism 3 and the injection mold, which is convenient for improving the rapid loading of metal parts.

[0034] A gasket 310 is provided between the second fixed seat 37 and the third finger cylinder 351. The design of the gasket 310 can adjust the position of the third finger cylinder 351 according to the actual application process to meet the loading requirements of different metal parts, so that the metal parts clamped by the third clamping jaw 352 can be accurately sent to the designated position of the injection mold under the drive of the second slide table cylinder 33 at a set telescopic distance.

[0035] Further, a positioning pin 39 is provided on one side of the second fixing base 37 where the third finger cylinder 351 is located. The positioning pin 39 is used to position the second fixing base 37 and the injection mold, improving the rapid feeding of metal parts.

[0036] Preferably, the support plate 4 and the support frame 2 are connected by fasteners. During installation, first, all structures of the part feeding mechanism 3 are installed on the support plate 4, and then the support plate 4 is installed on the support frame 2 through fasteners.

[0037] In this embodiment, a set of limit fixing seats 11 for fixing the support frame 2 are provided on the base 1, and both sides of the support frame 2 are locked and fixed to the limit fixing seats 11 through fasteners.

[0038] As shown in FIG. 7, a plurality of wire passing holes 110 are provided on the limit fixing seat 11. Inclined surfaces 12 are provided on both sides of the base 1, and the inclined surfaces 12 are adapted to the locking latches 101 on the locking fixing plate 100 of the ABB robot. An adjusting handle is provided on the locking latch 101. By rotating the adjusting handle, the locking latch 101 can be controlled to move away from or close to the inclined surface 12. When the locking latch 101 approaches the inclined surface 12 under the control of the adjusting handle, the base 1 can be firmly fixed on the locking fixing plate 100, thereby realizing the installation of the manipulator and the ABB robot.

[0039] Based on the injection mold part picking and placing manipulator in the above embodiment, its specific working process is as follows:

[0040] (1) The ABB robot controls the manipulator to approach the feeding table. The first clamping mechanism 34 is extended by the first sliding table cylinder 32, and the second clamping mechanism 35 is extended by the second sliding table cylinder 33. The first clamping mechanism 34 and the second clamping mechanism 35 are used to automatically pick metal parts respectively.

[0041] (2) After picking up the parts, the ABB robot controls the manipulator to automatically align with the mold position. The injection molded product is taken out from the injection mold by the injection molded product taking out mechanism 5 and sent to the designated position.

[0042] (3) After taking away the injection molded product, the manipulator is shifted to move the first clamping mechanism 34 and the second clamping mechanism 35 to the designated position inside the injection mold.

[0043] (4) The first sliding table cylinder 32 controls the first clamping mechanism 34 to drive the metal part close to one inner wall of the injection mold, and the second sliding table cylinder 33 controls the second clamping mechanism 35 to drive the metal part close to the other inner wall of the injection mold. Finally, the first clamping mechanism 34 and the second clamping mechanism 35 automatically place the metal parts in the injection mold.

[0044] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the utility model.
