Description

Technical Field

[0001] This invention relates to the field of auxiliary slip ring injection molding, specifically to an auxiliary slip ring injection molding production carrier. Background Technology

[0002] Slip rings, also known as conductor rings, current collectors, or collector rings, are used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. Slip rings improve system performance, simplify system structure, and prevent wires from twisting during rotation.

[0003] Depend on Figure 1 It can be seen that after the copper ring 11 and the insert 12 are welded together, they form a slip ring. Figure 2 It can be seen that the lower part of the collector ring is injection molded and wrapped with plastic, ultimately forming the finished collector ring 13, while the upper copper ring 11 is not covered with plastic. For the production of this type of product, due to the limitations of its product structure, a mold is usually made. In the mold, the copper rings 11 are generally arranged with the head of the copper ring facing down, four in a row or eight in a row, and then injection molded into the finished collector ring 13. This inverted placement method:

[0004] Firstly, the operators need to use their hands to pick up and place the parts into the mold cavity for assembly, which is not easy. The operating temperature of the mold cavity is generally around 120 degrees Celsius, which makes it very easy to burn the operator's fingers, resulting in very low production efficiency.

[0005] Secondly, it is difficult to accurately position the device by hand. If it is tilted, it is difficult to straighten it. It needs to be removed and reinstalled, which is time-consuming and laborious, and can easily damage the slip ring.

[0006] Therefore, it is necessary to invent an auxiliary current collector ring for injection molding of carrier disks.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art. Summary of the Invention

[0008] The purpose of this invention is to provide an auxiliary carrier for injection molding of current collector rings, in order to solve the problems in the prior art where operators directly contact the mold cavity for assembly, which is not easy to place, easily burns fingers, and is difficult to accurately position by hand, and is difficult to reshape after being misaligned.

[0009] To achieve the above objectives, the specific technical solution of the present invention for the injection molding production of carrier disks using an auxiliary current collector ring is as follows:

[0010] A carrier plate for injection molding of auxiliary slip rings includes a base plate with an opening in the middle. Support plates are vertically arranged on both sides of the upper part of the base plate. A panel is installed on the upper part of the support plates. Several positioning devices are provided on the upper surface of the panel. Two positioning pins are fixedly arranged on both sides of the positioning devices. An elastic device is movably arranged between the base plate and the panel. An ejection structure is fixed on the elastic device to push out the workpiece to be processed in the positioning device.

[0011] Furthermore, the positioning device includes a positioning block, which is fixedly disposed on the upper surface of the panel. The positioning block has a positioning socket in the middle and positioning ports symmetrically arranged on both sides. Spring positioning pins are symmetrically arranged between the positioning ports and the positioning sockets.

[0012] Furthermore, the elastic device includes a push plate, and linear bearings are installed near the four corners of the push plate. Each linear bearing is fitted with a connecting rod, which is vertically arranged between the base plate and the panel. Springs are fitted on the connecting rods between the push plate and the panel.

[0013] Furthermore, the ejection structure includes a top block base plate, which is fixed to the upper surface of the push plate. A first top block and a second top block are fixedly provided on the top block base plate. Both the first top block and the second top block pass through the panel and are respectively inserted into the positioning port and the positioning socket.

[0014] Furthermore, four positioning devices are provided on the upper surface of the panel, arranged in a straight line, and support columns are provided near the four corners of the upper surface of the panel.

[0015] Furthermore, a cross groove is cut from the top of the spring positioning pin to the bottom.

[0016] Furthermore, the upper part of the positioning socket is symmetrically provided with movable ball-head plungers.

[0017] Furthermore, the lower surface of the push plate is provided with an auxiliary pressing plate that is adapted to the opening.

[0018] Furthermore, handles I are fixedly provided on both sides of the support plate, and handles II are vertically provided on both sides of the opening at the bottom of the base plate.

[0019] Furthermore, the base plate, the front panel, and the support plate are detachably fixed together by bolts.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention utilizes an elastic device to push the ejector structure to push out the collector ring inside the positioning device, avoiding the risk of burns caused by direct contact between human hands and the mold cavity, thus improving production efficiency. Furthermore, through the auxiliary cooperation between the positioning pin and the positioning hole on the mold, precise positioning is achieved, avoiding the low accuracy of human hand placement, which can easily lead to skewness and make it difficult to shape. This improves the injection molding quality of the product, reduces the product scrap rate, and saves costs.

[0022] 2. The slip ring is further secured by spring positioning pins and ball-head plungers, making it less likely to fall off during flipping and improving reliability; the support column ensures that the panel plane and the mold surface are relatively flush, maintaining a safe ejection distance.

Detailed implementation method:

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 3 to 6As shown, an auxiliary slip ring injection molding production carrier is designed, including a base plate 1. An opening 101 is provided in the middle of the base plate 1. The opening 101 can be square, rectangular, or circular. Support plates 2 are vertically mounted on both sides of the upper part of the base plate 1. A panel 3 is mounted on the upper end of the support plates 2. Several positioning devices 4 are provided on the upper surface of the panel 3. Two positioning pins 7 are staggered and fixed on both sides of the positioning devices 4. The positioning pins 7 cooperate with the positioning holes on the mold to achieve precise positioning. The ends of the two positioning pins 7 are rounded to facilitate insertion and avoid hard contact. The base plate 1 and the panel... An elastic device 5 is provided between the three parts. An ejector structure 6 is fixed on the elastic device 5 to push out the workpiece to be processed in the positioning device 4. By using the elastic device 5 to drive the ejector structure 6 to push out the slip ring to be processed in the positioning device 4, the risk of burns caused by direct contact between the human hand and the mold cavity is avoided, and the production efficiency is improved. Furthermore, the positioning pin 7 cooperates with the positioning hole on the mold to achieve precise positioning, avoiding the low accuracy of human hand placement, which is prone to skew and makes it difficult to shape. This improves the injection molding quality of the product, reduces the product scrap rate, and saves costs.

[0032] like Figures 3 to 6 As shown, the positioning device 4 includes a positioning block 41, which is fixed to the upper surface of the panel 3 by bolts for easy disassembly. The positioning block 41 has a positioning socket 42 in the middle and positioning ports 43 symmetrically arranged on both sides. The size of the positioning socket 42 and the two positioning ports 43 is adapted to the slip ring, and its function is to fix the slip ring. The preferred shape of the positioning block 41 is "convex", which is more suitable for fitting the shape of the slip ring and making its fixing effect better. Spring positioning pins 44 are symmetrically arranged between the positioning ports 43 and the positioning socket 42. The spring positioning pins 44 are made of 65MN spring steel, which is strong and not easy to break. The top of the spring positioning pin 44 is cut with a cross groove to the bottom to increase the elasticity and achieve the tensioning effect. The upper part of the positioning socket 42 is provided with two movable ball plungers 45, and the two ball plungers 45 are symmetrically arranged. The spring positioning pins 44 and the ball plungers 45 are used for auxiliary fixing of the slip ring, making it less likely to fall off when flipped, thus increasing reliability.

[0033] like Figures 3 to 6As shown, the elastic device 5 includes a push plate 51, which is smaller than the base plate 1 and the panel 3. The four corners of the push plate 51 are rounded to avoid rigid contact during disassembly and assembly. Linear bearings 52 are installed near the four corners of the push plate 51, and each linear bearing 52 is fitted with a connecting rod 53. The push plate 51 can move up and down through the sliding cooperation between the linear bearings 52 and the connecting rods 53. The connecting rods 53 are vertically set between the base plate 1 and the panel 3. The two ends of the connecting rods 53 can be detachably fixed to the base plate 1 and the panel 3 by bolts, which facilitates disassembly. Springs 55 are fitted on the connecting rods 53 between the push plate 51 and the panel 3. When pressed down, the spring force of the springs 55 can quickly reset the push plate 51. An auxiliary pressing plate 54 adapted to the opening 101 is provided on the lower surface of the push plate 51 to facilitate manual pressing and push-out action.

[0034] like Figures 3 to 6 As shown, the ejection structure 6 includes a top block base plate 61, which is fixed to the upper surface of the push plate 51 by welding. Welding provides better fixation. A first top block 62 and a second top block 63 are welded and fixed on the top block base plate 61. Both the first top block 62 and the second top block 63 pass through the panel 3 and are respectively inserted into the positioning port 43 and the positioning insertion port 42. When the push plate 51 is pushed by hand, the first top block 62 and the second top block 63 push out the slip ring installed in the positioning device 4 through their joint ejection action.

[0035] like Figures 3 to 6 As shown, four positioning devices 4 are arranged in a straight line on the upper surface of panel 3. The push plate 51 also has ejection structures 6 corresponding to the four positioning devices 4. The four positioning devices 4 can simultaneously eject several slip rings to be processed, improving production efficiency and saving time.

[0036] Support columns 8 are bolted to the upper surface of panel 3 near the four corners. The support columns 8 are used to support panel 3 on the kapok, so that the plane of panel 3 and the mold surface are relatively flush and can maintain a safe ejection distance. Handles I 9 are fixed on both sides of support plate 2 to help pick up the tray. Handles II 10 are vertically installed on both sides of the opening 101 at the bottom of the base plate 1 to assist in support and easy hand holding. The base plate 1, panel 3 and support plate 2 are detachably fixed with bolts, which can be easily assembled and disassembled.

[0037] Working principle and usage process: First, place the entire slip ring of the workpiece into the positioning block 41 for positioning. With the auxiliary fixing effect of the spring positioning pin 44 and the ball plunger 45, the slip ring will not fall out even if the carrier plate is flipped. After installation, the operator grabs the handles I9 on both sides, lifts the carrier plate, flips it 180 degrees and places it on the mold surface. The panel 3 is flush with the mold surface under the action of the support column 8. The positioning pin 7 and the positioning hole on the mold surface are positioned and engaged. Then, grab the lower handle II10 and press the auxiliary pressing plate 54 with your thumb. The linear bearing 52, spring 55 and push plate 51 are used to push the first top block 62 and the second top block 63 to push the slip ring in the positioning block 41, thus pushing the slip ring to be processed into the mold cavity. Then, remove the carrier plate, and the operation process is completed.
