Description

In the power supply system, it plays the role of connecting the main switch in the electrical cabinet with the switches in each branch circuit. The existing busbar is generally composed of a conductive plate and an insulating layer arranged on the outside of the conductive plate. If the material of the insulating layer is insulating plastic, during the production process of the copper busbar, it is generally necessary to use an injection mold to perform integrated injection molding of the insulating layer on the outside of the conductive plate. During production, the mold is divided into a lower mold and an upper mold. After the conductive plate is placed inside the lower mold, the upper mold is installed to form an injection cavity inside the lower mold and the upper mold. The injection molding material is introduced into the injection molding cavity from the injection molding tube at the top of the upper mold to fill the entire injection molding cavity.

The operation is convenient and simple, and the work efficiency is improved.

[0026] Working principle: During operation, the conductive plate 301 is first placed inside the lower mold 201 so that the bottom wall of the conductive plate 301 contacts the bottom wall of the end groove 203 on the lower mold 201. Then, the upper mold 202 is installed on the lower mold 201 to form an integral mold part. The two end grooves 203 at the same end of the lower mold 201 and the upper mold 202 form a mounting groove. The outer wall of the conductive plate 301 is in close contact with the inner wall of the mounting groove. The lower mold 201 is provided with a positioning groove, and the upper mold 202 is provided with a positioning column. During installation, the positioning column is inserted into the positioning groove. Then, the drive motor 404 is turned on to drive the double-headed screw 403 to rotate. Since the two sliding vertical plates 402 are respectively threadedly connected to the two thread grooves on the double-headed screw 403 with opposite directions, the two sliding vertical plates 402 are driven to move closer to each other until the two latching rods 4078 on the first plate 4071 are inserted into the latching grooves 20710 on the upper and lower connecting plates 2079 at corresponding positions. Then, the cylinder 4122 is turned on to push the transverse plate 4121 upward, producing the following effects: When the first plate 407 is pressed against the second end of the workpiece 2064, the first plate 407 is pressed against the first end of the workpiece 2064, and the second plate 407 is pressed against the first end of the workpiece 2064. Secondly, when the first plate 4071 moves along the fixed tooth plate 405, the first gear 4074 meshes with the fixed tooth plate 405, thereby driving the second gear 4075 to rotate, and the two sides of the second gear 4075 are respectively meshed with the two movable tooth plates 4076. After the second gear 4075 rotates, it drives the two clamping rods 4078 to move closer to each other, thereby pulling the upper and lower connecting plates 2079 closer to each other. When the connecting plates 2079 move to the extreme position, the lower mold 201 and the upper mold 202 are pressed tightly, ensuring the stability of the injection molding process and facilitating the pressing and fixing of the lower mold 201 and the upper mold 202. Finally, the transverse plate 4121 moves upward, causing the support plate 4125 to contact the bottom wall of the bottom plate 2054, and pushing the support block 2052 to move upward until the top wall of the support block 2052 contacts the bottom wall of the conductive plate 301, so that the support block 2052 supports the conductive plate 301 during the injection molding process, preventing the conductive plate 301 from being bent and deformed due to the feeding, thereby improving the stability of the injection molding process; Then, the injection molding process is carried out, the injection molding pipe is connected to the feed pipe 204, and the injection molding raw material is passed into the lower mold 201 and the upper mold 202. After most of the material is fed into the mold cavity, the electromagnet 4127 is energized to generate attraction to the magnetic block 4126, thereby driving the support plate 4125 to enter the side groove 4124, so that the supporting force of the support plate 4125 on the bottom plate 2054 disappears. At this time, the support block 2052 moves back downward under the elastic force of the first spring 2055 until the top wall of the support block 2052 is flush with the inner bottom wall of the lower mold 201. After the support block 2052 moves downward, the internal space of the lower mold 201 is increased, thereby generating negative pressure suction, which increases the force of the injection molding raw material to flow toward the bottom of the conductive plate 301, making it convenient for complete filling under the conductive plate 301 and facilitating the injection molding process; After the processing is completed, the injection molding material forms an insulating layer 302 on the outside of the conductive plate 301, thereby forming the busbar component 3, and then the various devices are returned to their positions, the upper mold 202 is removed, and the material is unloaded.
