Technical Field

[0001] This utility model relates to the field of injection molding part punching, and in particular to an automatic punching device for injection molding parts. Background Technology

[0002] Injection molded parts are plastic products manufactured through injection molding, and are widely used in industrial production and daily life. Injection molded parts are products with specific shapes and functions obtained by heating and melting plastic raw materials (such as granular polyethylene, polypropylene, polystyrene, etc.), injecting them into a pre-designed mold cavity under high pressure from an injection molding machine, and then cooling and solidifying them.

[0003] After injection molding, existing injection molded parts are usually removed from the injection molding machine by a robotic arm or manually, and then manually punched. However, this manual punching method has low efficiency, and the operator is prone to injury due to operational errors, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic punching device for injection molded parts. It has an ingenious structure and can achieve precise blanking and automated punching of injection molded parts, making it convenient and practical.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a transfer assembly installed on an injection molding machine and capable of transferring injection-molded parts, a frame, and multiple punching assemblies arranged parallel to the frame and capable of punching the injection-molded parts; the transfer assembly includes a first bracket that can be installed on the injection molding machine, a first drive motor mounted on the first bracket, a first linear module slidably mounted on the first bracket under the drive of the first drive motor, a second bracket slidably mounted on the first linear module under the drive of the first linear module, a lifting bracket mounted on the second bracket, a drive cylinder mounted on the lifting bracket, and a component rotatably mounted on the lifting bracket under the drive of the drive cylinder and capable of transferring injection-molded parts. The material handling assembly for removing injection molded parts from the injection molding machine has the first support and the second support moving perpendicularly to each other. The extension direction of the lifting support is perpendicular to both the first and second supports. The punching assembly includes a placement platform mounted on the frame for receiving and placing injection molded parts, a punching cylinder mounted on the frame, two opposing drive plates mounted on the punching cylinder, and cutters mounted on each mounting plate. The material handling assembly transfers the injection molded parts from the injection molding machine to the placement platform by driving the first linear module with the first drive motor, driving the second support with the first linear module, and driving the drive cylinder. Each cutter punches the injection molded parts by driving the mounting plate with the punching cylinder.

[0006] Furthermore, the aforementioned material handling assembly includes a right-angle rotating plate, a connecting plate fixed on the right-angle rotating plate, and multiple sets of pneumatic gripper assemblies mounted on the connecting plate. The right-angle rotating plate includes a first right-angle plate and a second right-angle plate that are perpendicular to each other. A first rotating seat is mounted on the first right-angle plate, and a second rotating seat is mounted on the second right-angle plate. The first and second rotating seats are integrally formed. The second rotating seat is rotatably connected to the lifting bracket. The extension end of the drive cylinder is rotatably connected to two opposing traction plates. The other end of each traction plate is rotatably connected to the first rotating seat. The pneumatic gripper assembly includes two opposing pneumatic grippers. Each pneumatic gripper has a material handling plate at its drive end. Each material handling plate on each opposing pneumatic gripper grips the injection molded part in the injection molding machine by driving the first rotating seat with the drive cylinder and by cooperating with the lifting bracket.

[0007] Furthermore, the telescopic end of the aforementioned punching cylinder is fixedly provided with a drive plate, and each mounting plate is arranged parallel to the drive plate. Each mounting plate has a clamping plate on its outer side that can clamp the injection molded part. The clamping plate is arranged parallel to the mounting plate, and each mounting plate is arranged between the clamping plates.

[0008] Furthermore, the aforementioned placement platform is provided with two placement bosses corresponding to each injection molded part. Each placement boss is provided with a positioning groove for positioning the injection molded part. Each positioning groove is provided with a positioning post for positioning the injection molded part. The positioning grooves are symmetrically arranged and the positioning posts in each positioning groove are symmetrically arranged.

[0009] Furthermore, the bottom of the frame is provided with a guide bin for discharging the cut waste. The guide bin includes a side bin plate fixed to the frame and an inclined guide plate fixed to the bottom of each side bin plate. The frame is provided with a through slot corresponding to each placement platform and communicating with the guide bin. The frame is provided with a baffle plate corresponding to each through slot and having a U-shaped cross section.

[0010] Furthermore, the aforementioned placement platform is provided with an inclined discharge ramp, which is located between each placement boss. The inlet diameter of the discharge ramp is smaller than the outlet diameter, and the inlet depth of the discharge ramp is smaller than the outlet depth.

[0011] This utility model has positive effects: (1) This utility model takes out the injection molded part from the injection molded part by setting a transfer component and transfers it to the punching component. The material taking component transfers the injection molded part in the injection molding machine to the placement platform by the first drive motor driving the first linear module, the first linear module driving the second bracket, and the drive cylinder driving. Each cutter punches the injection molded part by the punching cylinder driving the mounting plate. This effectively solves the problems of inefficiency and insecurity caused by manual punching in the prior art. By using automation, the injection molded part is automatically taken out and punched, which greatly improves the punching efficiency and punching quality of the injection molded part. The structure is ingenious, efficient and convenient.

[0012] (2) This utility model sets up a material picking component on the lifting bracket, and drives the first rotating seat to rotate by the drive cylinder. The second rotating seat and the lifting bracket are rotated in sync. At the same time, multiple pneumatic grippers are set up. During the process of each pneumatic gripper picking up the corresponding injection molded part and transferring it to the punching component, the injection molded part is reversed, thereby ensuring that each injection molded part can be stably positioned and placed on the placement platform. At the same time, the stability of the injection molded part in the circumferential process is also guaranteed, which is efficient and practical.

[0013] (3) By setting a clamping plate on the drive plate and setting the clamping plate and the cutter in parallel, the cooperation of each mounting plate and clamping plate during the punching process can ensure the overall stability of the injection molded part during the punching process, further ensuring the punching effect of the injection molded part in the later stage, which is stable and convenient.

[0014] (4) This utility model sets two opposite placement bosses, and sets positioning grooves on the placement bosses for positioning the injection molded parts. At the same time, positioning posts are set in each positioning groove. Through the cooperation between the positioning posts in each positioning groove and the injection molded parts, the stability of the injection molded parts in the positioning and punching process is further guaranteed, which is efficient and convenient.

[0015] (5) This utility model uses a guide bin at the bottom of the frame to discharge the punched waste material. During the discharge process, the U-shaped baffle plate can ensure that the punched waste material comes out of the guide bin during the discharge process, and can also guide the waste material into the guide bin, which is convenient and practical.

[0016] (6) By setting a feeding ramp on the placement platform and placing the feeding ramp between each placement boss, the waste material after the injection molding part is punched can automatically fall into the guide hopper through the guidance of the feeding ramp, avoiding the accumulation of waste material on the placement platform and affecting the overall punching effect in the later stage, which is efficient and convenient.
