Description

Technical Field

[0001] The utility model relates to the technical field of injection molding processing, in particular to a discharge and conveying device for special-shaped injection molding parts. Background Art

[0002] Injection molding is a method for producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding, compression molding and die casting. The injection molding machine is the main molding equipment that heats thermoplastic plastics or thermosetting plastics and injects them into the melt to make plastic products of various shapes according to the shape of the mold. Injection molding is achieved through the injection molding machine and the mold. After the injection molded parts are completed, they are mostly clamped by grippers to remove the processed injection molded parts from the injection molding machine. However, some injection molded parts are designed to have smooth surfaces and different shapes due to the needs of later use, such as curved injection molded parts. At this time, it is difficult for the grippers to effectively clamp the special-shaped injection molded parts, which can easily cause the injection molded parts to fall during the clamping process, causing the produced injection molded parts to be broken and affecting the subsequent normal use. In view of this, we propose a discharge and conveying device for special-shaped injection molded parts. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figures 1-6As shown, one of the purposes of this embodiment is to provide a discharge and conveying device for special-shaped injection molded parts, including a cylinder 1, a tooth plate 11 is fixedly provided at the piston end of the cylinder 1, and the working cylinder 1 drives the tooth plate 11 to move vertically up and down through the piston end, and a mounting bracket 3 is provided on the lower side of the cylinder 1, and the cylinder 1 and the mounting bracket 3 are connected by a mounting mechanism 2, and the mounting mechanism 2 is used to install the mounting bracket 3, and the mounting mechanism 2 includes a mounting shell 21 fixedly provided at the bottom of the cylinder 1, and the mounting shell 21 is sleeved on the outer side of the tooth plate 11, and a rotating block 22 is rotatably connected to the bottom of the mounting shell 21, and the mounting bracket 3 is fixedly provided at one end of the rotating block 22 away from the mounting shell 21, and a plurality of teeth are coaxially fixed on the top side wall of the rotating block 22, and the tooth plate 11 is meshed with the teeth, and the moving tooth plate 11 drives the rotating block 22 to rotate, and the maximum rotation angle of the rotating block 22 is 90 degrees. The mounting bracket 3 is installed at the bottom of the cylinder 1 through the mounting mechanism 2, When it is necessary to use the unloading device to remove the injection molded part, the cylinder 1 works by driving the gear plate 11 downward through the piston end. During the movement, the gear plate 11 drives the rotating block 22 engaged with the gear plate 11 to rotate. During the rotation of the rotating block 22, the rotating block 22 drives the mounting bracket 3 to rotate so that the mounting bracket 3 is parallel to the injection molded part. After the rotation is completed, the mounting bracket 3 collides with the mounting shell 21. In order to reduce the impact force between the mounting bracket 3 and the mounting shell 21, several buffer blocks corresponding to the positions are fixedly provided on the bottom and side walls of the mounting shell 21 and the surface of the mounting bracket 3. The buffer blocks are used to buffer the impact force between the rotation of the mounting bracket 3 and the mounting shell 21. When the mounting bracket 3 rotates close to the mounting shell 21, the mounting bracket 3 contacts the buffer blocks on the mounting shell 21, and the impact force between the mounting bracket 3 and the mounting shell 21 is buffered by the buffer blocks, thereby avoiding damage caused by the large impact force between the mounting bracket 3 and the mounting shell 21.

[0026] Since the surface of some injection molded parts is relatively smooth and there are injection molded parts with relatively strange shapes, it is easy to fall when the special-shaped injection molded parts are clamped by the clamping claws. In order to improve the stability of the injection molded parts during the removal process, a number of suction nozzles are provided on the lower side of the mounting frame 3. Each suction nozzle is installed on the mounting frame 3 through an adjusting mechanism 4. The adjusting mechanism 4 is used to install and adjust the suction nozzle. The adjusting mechanism 4 includes an adjusting block 42 arranged inside the mounting frame 3. An air pipe 45 is fixedly provided on the adjusting block 42. The suction nozzle is fixedly provided at one end of the air pipe 45. The movable adjusting block 42 is used to adjust the position of the suction nozzle. The air pipe 45 passes through the mounting block 41 at one end away from the suction nozzle and is fixedly provided with a connector. The joint connects the air pipe 45 to the external air pump. When the injection molded part needs to be removed, the mounting bracket 3 drives the suction nozzle to move so that the suction nozzle is tightly attached to the surface of the injection molded part. The air pump draws out the air inside the suction nozzle through the air pipe 45 to form a negative pressure, so that the injection molded part is tightly attached to the suction nozzle, and the surface of the injection molded part is smooth and not prone to air leakage, thereby effectively improving the stability of the injection molded part during the removal process. In order to facilitate the removal of the processed injection molded part, a connecting bracket is installed on the top of the cylinder 1, and the cylinder 1 is installed on the moving assembly through the connecting bracket. After the suction nozzle absorbs the injection molded part, the cylinder 1 and the injection molded part are driven to move through the moving assembly, thereby facilitating the removal of the injection molded part from the injection molding machine.

[0027] The moving component can be an electric telescopic rod, a hydraulic cylinder, etc., and the cylinder 1 can be driven to move by the moving component.

[0028] Since the surface heights of some injection molded parts are different, and the suction nozzles are on the same horizontal plane, it is difficult for the suction nozzle to effectively adsorb the injection molded parts. In order to further improve the adsorption stability of the suction nozzle on the injection molded parts, the adjustment mechanism 4 also includes a mounting block 41 fixedly arranged on the mounting frame 3. The surface of the mounting block 41 is rotatably connected to an adjusting nut 44. The adjusting block 42 is fixedly provided with an adjusting screw 43 on the side close to the mounting block 41. The adjusting screw 43 passes through the mounting block 41 at one end away from the adjusting block 42. The adjusting nut 44 is threadedly connected to the adjusting screw 43. The rotating adjusting nut 44 drives the adjusting screw 43 to move vertically up and down. When the surface height of the injection molded part that the suction nozzle needs to adsorb is different, the adjusting nut 44 is rotated by a tool. The adjusting nut 44 drives the adjusting screw 43 up and down through the thread during the rotation process, thereby driving the adjusting block 42 to move toward or away from the mounting block 41, and adjusting the position of each suction nozzle so that the suction nozzle can better fit the surface of the injection molded part, further improving the adsorption effect of the suction nozzle on the injection molded part.

[0029] Since the air pipe 45 is relatively soft, when the distance between the adjusting block 42 and the mounting block 41 is reduced, the air pipe 45 is prone to bend, which causes the adjusting block 42 and the mounting block 41 to squeeze the air pipe 45 and cause blockage. In order to avoid poor ventilation caused by the bending of the air pipe 45, a tension spring 46 is provided on the outside of the air pipe 45. The two ends of the tension spring 46 are respectively in contact with the side walls between the mounting block 41 and the adjusting block 42. When the adjusting block 42 moves toward the direction close to the mounting block 41, the tension spring 46 in the stretched state recovers and contracts, limiting the position of the air pipe 45 inside the tension spring 46, thereby avoiding the adjustment block 42 and the mounting block 41 from being close to each other and causing the air pipe 45 to be bent, which affects the normal use of the air pipe 45. 3 needs to move with the rotation of the adjusting nut 44. In order to prevent the adjusting block 42 and the adjusting screw 43 from rotating with the rotation of the adjusting nut 44, a through limiting hole is opened on the surface of the mounting block 41. A limiting rod is fixedly provided on the adjusting block 42 near the surface of the mounting block 41. The limiting rod slides through the limiting hole on the mounting block 41 at one end away from the adjusting block 42. The limiting rod cooperates with the adjusting screw 43 to ensure that the adjusting block 42 is always parallel to the mounting block 41, preventing the adjusting block 42 from rotating when the adjusting screw 43 is driven up and down by the adjusting nut 44. The adjusting block 42 blocks the adjusting screw 43 from rotating together with the adjusting nut 44, ensuring that the position of the adjusting block 42 will not be offset, thereby improving the stability of the adjusting block 42 during movement and use.

[0030] In summary, the working principle of this solution is as follows: first, the suction nozzle is installed at one end of the air pipe 45, and then the suction nozzle is installed on the mounting bracket 3 through the adjusting mechanism 4, and the adjusting nut 44 is turned by the wrench to make the adjusting screw 43 drive the adjusting block 42 and the suction nozzle to move, and by adjusting several adjusting mechanisms 4, the suction nozzles on several adjusting mechanisms 4 are made to have the same height as the side wall of the special-shaped injection molded part that needs to be adsorbed, so that the suction nozzle can fit the surface of the injection molded part more effectively. During the movement of the adjusting block 42, the position of the air pipe 45 is limited inside the tension spring 46 to avoid the air pipe 45 from bending and causing blockage. The mounting bracket 3 is installed on the bottom of the cylinder 1 through the mounting mechanism 2, and finally the air pipe 45 is connected to the air pump through the connector. When needed When taking out the completed injection molded part, the cylinder 1 works to drive the gear plate 11 to move through the piston end. During the movement, the gear plate 11 drives the rotating block 22 engaged with the gear plate 11 to rotate, thereby driving the mounting frame 3 to rotate, so that the mounting frame 3 is parallel to the injection molded part, and the mounting frame 3 is driven by the moving component to move toward the direction close to the injection molded part, so that the suction nozzle is tightly attached to the surface of the injection molded part. Subsequently, the air pump works to extract the air inside the suction nozzle through the air pipe 45 to form a negative pressure, so that the injection molded part is stably attached to the suction nozzle to prevent the injection molded part from falling during the movement. After the suction nozzle absorbs the injection molded part, the moving component works to drive the mounting frame 3 and the injection molded part to move, and the processed injection molded part is removed from the injection molding machine, thereby facilitating the subsequent use of the injection molding machine.
