Description

Material receiving and deburring device for injection molding part Technical Field The utility model belongs to the technical field of injection molding processing automation equipment, and particularly relates to a receiving and deburring device for injection molding parts. Background In the production process of BMC (Bulk Molding Compound) injection molding parts, the injection molding parts are taken out from the mold and then are subjected to material receiving and burr treatment so as to ensure the dimensional accuracy and the surface quality of the products. However, the prior art has the following significant problems in this link: 1. The damage to the injection molding part caused by unreasonable unloading height is that the traditional manipulator usually directly unloads the injection molding part at a higher position to the conveyor belt after taking the injection molding part out of the mold cavity. If the unloading height is too high, the injection molding part is easy to collide with the conveyor belt or other parts due to free falling body movement, so that the injection molding part is defective, and if the unloading height is too low, the distance between the manipulator and the conveyor belt is insufficient, the injection molding part can be crushed. This contradiction results in a decrease in yield of injection molded parts, while frequent adjustments of equipment parameters are required to reduce production efficiency. 2. The burr overflow trough is not automatically treated, and the parting surface of the BMC injection molding part is easy to generate the burr overflow trough in the molding process. In the prior art, the manipulator does not integrate the burr cutting function after taking out the injection molding, and the burrs are removed by depending on a subsequent sand blasting process. Untreated burrs, however, may fall out during the blasting process, blocking the blaster grit recovery line. This problem forces the production line to additionally arrange manual posts for burr manual cleaning, not only increases the labor cost, but also causes productivity loss due to shutdown blocking. Although some schemes attempt to alleviate the problems by optimizing the path of the manipulator or adding an independent burr treatment station, there are still limitations in that the independent burr cutting equipment needs to position the injection molding for the second time, the takt time is increased, the requirement of high-efficiency continuous production is difficult to meet, the adjustment of the unloading height of the manipulator depends on a complex sensor feedback system, the cost is high, the stability is not enough, and the lack of integrated design leads to large occupied area of the equipment and poor synergy. Disclosure of utility model The utility model provides a receiving and deburring device for injection molding parts, which aims to solve the technical problems in the prior art. The utility model provides a receiving and deburring device for an injection molding piece, which comprises an injection molding piece clamping mechanism, a displacement mechanism and a burr cutting mechanism, wherein the displacement mechanism is connected with the injection molding piece clamping mechanism to drive the injection molding piece clamping mechanism to switch between an initial receiving position and a discharging position, the height of the initial receiving position is higher than that of the discharging position, and the burr cutting mechanism comprises a liftable cutting assembly arranged below the injection molding piece clamping mechanism.
