Description

Technical Field

[0001] The invention relates to the technical field of cathode plate edge sealing injection molding, in particular to an electrolytic cathode plate double edge sealing automatic injection molding device. Background Art

[0002] The quality of the electrolytic cathode plate plays a key role in the efficiency and product quality of electrolytic production. Among them, the edge sealing treatment of the cathode plate is an important link to ensure its stable performance. The traditional electrolytic cathode plate edge sealing process mostly adopts manual operation or semi-automatic injection molding. Manual edge sealing is not only inefficient and difficult to meet the needs of large-scale production, but also the edge sealing quality is greatly affected by the workers' technical level and working status, and is prone to problems such as uneven edge sealing and poor sealing.

[0003] The current cathode plate injection molding process for electrolysis has the following problems: in the cathode plate injection molding process, the semi-automatic injection molding method is to directly clamp the plate, embed it in the hot-melt plastic raw material, and then cool it to achieve edge-sealed injection molding. However, the thickness of the injection layer obtained in this way is different. Since the position of the cathode plate is difficult to standardize and fix, the life of the insulation layer of the subsequent cathode plate during use is also different, resulting in a faster loss of conductive efficiency. The current injection molding equipment cannot achieve standardized injection molding of the cathode plate and reduce the waste of raw materials. The existing technology is not easy to solve such problems.

[0036] When the present invention is used: the entire injection molding device includes three steps of feeding, injection molding and discharging during the process of injection molding of the cathode plate:

[0037] Feeding: The feeding process is the process of placing and clamping the cathode plate. The servo 16 controls the two top adjusting clamps 10 to rise. The operator places the cathode plate in the middle of the bottom fixed clamp 11. The servo 16 controls the top adjusting clamp 10 to descend and cover and clamp the cathode plate. The bottom of the first push rod 17 is clamped into the inside of the locking block 19. The top adjusting clamp 10 is clamped and tightened through the contraction process of the first push rod 17.

[0038] Injection molding: After the cathode plate is clamped and stabilized, it is moved to the middle position. The injection molding mechanisms on both sides begin to perform injection molding on both sides of the cathode plate to achieve insulation. The injection molding bases 5 on both sides are moved to place the cathode plate into the injection molding chamber 15. The distance between the top of the top adjusting clamping plate 10 and the bottom of the bottom fixing clamping plate 11 is the same as the height of the injection molding chamber 15. When moving and embedding, the internal sealing of the injection molding chamber 15 is ensured. The second push rods 6 at both ends are extended to move the adjusting inner blocks 13 at both ends to contact the ends of the top adjusting clamping plate 10 and the bottom fixing clamping plate 11 and achieve sealing. After sealing, injection molding begins. During the process, the corresponding feed control valve 9 is opened, and the feed motor rotates to drive the feed screw 26 to feed material, so as to realize quantitative feeding. After feeding, the third push rod 29 is extended, and the feed chamber 27 is sealed by the sealing slide plate 28. The injection molding mechanisms at both sides continue to move toward the middle, and the cathode plate is inserted into the internal injection molding chamber 15. The injection molding material is filled to wrap the cathode plate. During the injection molding process, the excess material enters the overflow discharge port 31 through the overflow feed port 30 to be discharged from the discharge device. The refrigeration end of the semiconductor refrigeration block 20 quickly shapes the position after injection molding, and the coolant circulates to quickly discharge the heat generated by the semiconductor refrigeration block 20.

[0039] Material discharging: The injection molding mechanisms at both sides are moved out, and the steering gear 16 controls the top adjusting clamping plate 10 to open and take out the cathode plate after injection molding, thus completing the material discharging work after the double-edge sealed cathode plate is injected.
