Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a bearing injection molding production line. Background Technology

[0002] Injection-molded bearings refer to bearings with a plastic structural component encapsulated on their surface, facilitating connections between bearing structures and simplifying assembly. Injection-molded bearings utilize injection molding technology. Conventional single-piece injection molding leaves an injection terminal on the product blank, requiring manual cleaning. To improve processing efficiency, injection molds typically have multiple molding stations interconnected by guide grooves, allowing multiple bearing parts to be produced in a single injection. However, the molded workpiece contains a connecting rod structure. Due to the relatively wear-resistant and hard plastic terminals used in bearings, manually cleaning this connecting rod structure is laborious, leading to low production efficiency and a higher likelihood of defective products. Therefore, current technology requires further improvement and development. Utility Model Content

[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-4As shown, the bearing injection molding production line of this utility model includes an injection molding machine 1, a feeding assembly, and a cutting mechanism. The injection molding machine 1 is equipped with a loading die head 11 and a unloading die head 12, which are paired to form several cavities. The injection molding machine 1 is equipped with a traveling platform 2, which is equipped with two traveling drivers 21 that can move along it. One traveling driver 21 is equipped with a feeding robot 22, and the other traveling driver 21 is equipped with an unloading robot 23. The feeding robot 22 can move between the feeding assembly and the loading die head 11, and can pick up several bearings from the feeding assembly and transfer them to the loading die head 11. The unloading robot 23 can move between the unloading die head 12 and the cutting mechanism, and can transfer the finished sheet shape on the unloading die head 12 to the cutting mechanism. The injection molding machine 1 is existing technology. Its loading die head 11 and unloading die head 12 are paired to form a cavity for injection molding. The loading robot 22 can transfer bearings in batches from the loading assembly to the loading die head 11. The unloading robot 22 can pick up finished products from the unloading die head 12 and transfer them to the cutting assembly for slitting. After the unloading die head 12 is paired with the loading die head 11, injection molding is performed. After mold opening, the unloading die head 12 moves away from the loading die head 11. The loading and unloading robots 22 move synchronously along the traveling platform 2, performing loading and unloading operations respectively. Then, the unloading die head 12 is paired with the loading die head 11 again. Simultaneously, the loading robot 22 moves to the loading assembly to pick up bearings, while the unloading robot 23 moves the finished sheet material to the cutting mechanism. The above process is repeated continuously, resulting in high production efficiency and a high degree of automation, effectively improving production benefits.

[0023] The unloading robot 23 is connected to the travel driver 21 via a reversing driver 24. The processing surface of the unloading die 12 is vertical, and the finished plate is vertically mounted on the unloading die 12. The processing surface of the cutting assembly is horizontal. After the unloading robot 23 picks up the finished plate from the unloading die 12, it rotates 90° via the reversing driver 24 and then places the finished plate on the cutting assembly.

[0024] Specifically, the cutting mechanism includes a base 3, with a processing table 31 at its upper end. The processing table 31 has a transfer track 32 and a support 33. The transfer track 32 has a movable receiving plate 34, along which a clamping assembly is mounted. A material distribution hopper 35 is located below the processing table 31. The support 33 is located at one end of the transfer track 32 and has a cutting assembly mounted on it. The transfer track 32 has two loading stations and a cutting station. The receiving plate 34 can reciprocate between the loading and cutting stations via the transfer track 32. The unloading robot 23 places the finished sheet material onto the receiving plate 34 at the loading station. The support 33 is located at the cutting station, and the cutting assembly is mounted on the support 33. After the receiving plate 34 moves to the cutting station, the cutting assembly cuts the finished sheet material, and the finished product falls into the finished product box via the material distribution hopper 35. Excess waste material falls into the waste box via the material distribution hopper 35.

[0025] The cutting assembly includes a base plate 4, a pressure cylinder 41, and an actuating plate 42. The base plate 4 is fixed to the upper end of the support 33, and the pressure cylinder 41 is fixed to the base plate 4. The actuating plate 42 is movably disposed between the base plate 4 and the transfer track 32. The base plate 4 is provided with several bearing seats 43, and the bearing seats 43 are provided with guide rods 44. The guide rods 44 are movably inserted through the bearing seats 43, and the lower end of the guide rods 44 is fixedly connected to the actuating plate 42. The actuating plate 42 is provided with several cutting blades 45, and the output shaft of the pressure cylinder 41 is fixedly connected to the actuating plate 42. It can be understood that the support plate 34 is provided with a fixing groove to position the finished plate, and the clamping assembly fixes the finished plate on the support plate 34 before cutting. The pressure cylinder 41 drives the actuating plate 42 to move downward, driving the cutting blades 45 to cut off the excess injection-molded terminals on the finished product. The bearing seats 43 and the guide rods 44 are used to control the movement trajectory of the actuating plate 42 and the cutting blades 45.

[0026] The support plate 34 can be replaced according to the product type. Furthermore, the actuating plate 42 is provided with several fixing holes, and the cutting blade 45 is mounted on the corresponding fixing holes through the adapter plate 46. The cutting blade 45 can also be replaced and adjusted through the adapter plate 46.

[0027] The receiving plate 34 is mounted on the transfer track 32 via a slider, and a stroke driver 36 is provided on the processing table 31; the receiving plate 34 is provided with a linkage part 37, and the stroke driver 36 is connected to the linkage part 37 to drive the receiving plate 34 to reciprocate on the transfer track 32; both ends of the transfer track 32 are provided with limit switches 38, and the base 3 is provided with an electrical control box 39, which is connected to the limit switches 38, the stroke driver 36 and the booster cylinder 41 via wiring.

[0028] It can be understood that the stroke driver 36 can use a cylinder or a motor. Taking the motor as an example, the stroke driver 36 includes a lead screw and a slider. The lead screw drives the slider through a thread to make it perform a linear motion. Of course, the linkage part 37 is connected to the slider on the lead screw, and the motor rotates forward / backward to drive the lead screw to rotate, so that the receiving plate 34 reciprocates between the loading station and the cutting station.

[0029] Furthermore, the cutting knife 45 of the present utility model is a linear tool. The position accuracy of the receiving plate 34 between the loading station and the cutting station does not need to be very precise, and the travel switch 38 is only used as a trigger for circuit control. Of course, the travel switch 38 can also be replaced with a microswitch or other trigger elements to achieve precise position control.

[0030] The loading component includes a vibrating disk 5 and an arranging template 51. The vibrating disk 5 sequentially conveys a plurality of bearings to the arranging template 51, and the loading manipulator 22 can grasp a plurality of bearings on the arranging template 51 and transfer them to the loading die head 11. The vibrating disk 5 is a conventional existing technology. The vibrating disk 5 is used to sort and convey the bearings to the arranging template 51, so that the loading manipulator 22 can grasp the bearings in batches.

[0031] The injection molding machine 1, the loading component and the cutting mechanism are arranged in a "pin" shape; the walking platform 2 includes an X-axis track 25 and two Y-axis tracks 26. There is one Y-axis track 26 between the injection molding machine 1 and the loading component, and there is another Y-axis track 26 between the injection molding machine 1 and the cutting mechanism; the X-axis track 25 is erected between the two Y-axis tracks 26, and the X-axis track 25 can be horizontally translated along the Y-axis track 26; the walking driver 21 is movably arranged on the X-axis track 25.
