DETAILED DESCRIPTION

[0018] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0019] Please refer to Figs. 1-3 The mechanical arm structure for taking injection molded parts in the embodiment comprises a connecting plate 1 fixed with a mobile end of an external gantry truss, a right side of the connecting plate 1 is hingedly connected with a pushing cylinder 4, a piston rod of the pushing cylinder 4 is hingedly connected with a hinge plate 6, a bottom of the connecting plate 1 is provided with a lower hinge block 5, an inner side of the lower hinge block 5 is hingedly connected with a support plate fixed with the hinge plate 6, a bottom of the hinge plate 6 is fixed with a sleeve block 7, an inside of the sleeve block 7 is provided with a support profile 8, two oppositely distributed lower profiles 9 are arranged on a top of the support profile 8, a profile rack 12 is arranged on a tail end back surface of the support profile 8, a bottom of the profile rack 12 and bottoms of the two lower profiles 9 are provided with a pair of pushing cylinders 14, a piston rod of the pushing cylinder 14 is fixed with a push plate 19, and a demolding agent 13 is arranged on an inner side of the profile rack 12.

[0020] In the above structure, the connecting plate can be moved by the external gantry truss, so that the mechanical arm is moved into the injection molding machine to complete the operation. In the initial state, the pushing cylinder drives the hinge plate to be ejected, pushes the support profile to be on the same axis as the connecting plate, and then enters the injection molding machine to make the mold be ejected. The injection molded part is clamped and fixed by the push plate driven by the two pushing cylinders on the lower profile, and then the moving part on the connecting plate is moved to make the demolding agent opposite to one side of the mold. The demolding agent is pressed by the push plate driven by the pushing cylinder on the profile rack to complete the spraying of the mold. Until the connecting plate returns to the top point, the pushing cylinder is retracted, so that the connecting plate and the support profile are in L shape. The product can be placed on the external conveying table by cooperating with the gantry truss. Therefore, manual taking and spraying of the demolding agent can be avoided, and the safety of the workers can be improved.

[0021] In the above structure, the connecting plate 1 is provided with a slot 2 on the right side, and the slot 2 is fixed with an upper hinge block 3 hingedly connected with the pushing cylinder 4. One end of the upper hinge block 3 extends out of the slot 2. The hinge plate 6 is in L shape, and a top opening is arranged on the top. The slot and the upper hinge block can leave a certain gap between one side of the pushing cylinder and the connecting plate. At the same time, the top opening on the hinge plate can provide a side movement range of the piston rod of the pushing cylinder during the pushing process.

[0022] In addition, the support profile 8 is slidingly connected with the sleeve block 7, and the support profile 8 is locked by the screw penetrating through the sleeve block 7. Therefore, the length of the support profile can be adjusted according to the requirements.

[0023] As Fig. 2The positioning plates 10 are slidably connected between the front and rear sides of the support profile 8 and the top of the two lower profiles 9, the number of the positioning plates 10 is four, and the four positioning plates 10 are fixed through the bolts 11. Therefore, the positions of the two lower profiles and the two pushing cylinders can be adjusted by sliding the positioning plates on the support profile, and the positions of the two lower profiles and the two pushing cylinders can be adjusted by sliding the lower profiles on the positioning plates.

[0024] The pushing cylinders 14 on the lower profiles 9 are oppositely distributed, and the rubber blocks are fixed on the opposite sides of the two push plates 19. When the push plates are clamped to hold the injection molded part by the pushing cylinders, the rubber blocks can prevent damage to the outside of the injection molded part.

[0025] As shown in the drawings, Fig. 3 The profile frame 12 is fixed by three profiles and the positioning plates 10, the release agent 13 on the profile frame 12 is fixed by the belt 15, and the opposite sides of the two profiles at the tail end of the profile frame 12 are fixed by the support blocks 21 through screws. The support blocks serve to limit the release agent, prevent the release agent from being pressed to move, and fix the release agent by the belt, which is convenient for replacement.

[0026] The piston rod of the pushing cylinder 4 on the profile frame 12 is fixed with the limiting plate 14, the limiting plate 14 is in the shape of a concave letter, and the protruding plate surface can also have two sliding grooves. The inner side surface of the limiting plate 14 is sleeved with two guide columns 20, the outer side of the guide column 20 is sleeved with a spring 18, and the push plate 19 located at the pushing cylinder 4 is fixed with the two guide columns 20 and slides in the two sliding grooves. When the limiting plate is pushed forward by the pushing cylinder, the push plate is pressed on the release agent, and the guide column can be pushed to move backward by one end, and the spring is extruded at the same time. Under the action of the spring, the buffer effect can be achieved. When the pushing cylinder retreats, the limiting plate can always be attached to the nozzle end of the release agent, avoiding the nozzle from deviating or separating, and the sliding groove can also limit the push plate.

[0027] The working principle of the above embodiment is as follows:

[0028] First, in the initial state, the connecting plate and the support profile are vertically downward, and the injection molding machine is driven by the moving end of the external gantry truss until the two pushing cylinders on the lower profile are opposite to the injection molded part. After the injection molded part is ejected, the injection molded part is clamped and fixed by the push plate driven by the pushing cylinder, and then the moving end of the gantry truss moves upward by a certain distance, so that the release agent is opposite to the mold. At this time, the push plate on the profile frame is pressed downward by the pushing cylinder, and the release agent is sprayed on the mold. The gantry truss is moved to the top, and the hinge plate is reset by the pushing cylinder retreating, so that the connecting plate and the support profile are in the shape of L. By moving the gantry truss, the injection molded part can be placed on the external conveying table.

[0029] In summary, automatic picking and spraying can be realized, thereby improving the safety of workers and the efficiency of production.
