Description

Technical Field

[0001] The invention relates to the technical field of lead-tin alloy product forming, in particular to a semicircular lead-tin anode extrusion forming die. Background Art

[0002] Lead-tin anode plate is an important material used in the electrochemical industry, usually used for anodes in electrolytic cells. Semicircular lead-tin anodes are widely used in electrolytic cells and reaction vessels because of their high conductivity, good corrosion resistance, stable structure and wide adaptability. Similarly, semicircular lead-tin anodes are easier to process and produce than other complex shapes, which can improve production efficiency and reduce costs. In the process of producing lead-tin anodes for electrolytic cells, the number of lead-tin anodes is relatively large. Generally, the lead-tin alloy raw material is heated, and a part is cut by a cutting machine and placed at the inlet of the mold, and then the metal raw material is extruded by an extruder. After the extrusion is completed, the residual metal raw material in the mold is taken out, and then the above steps are repeated to produce the next lead-tin anode. Therefore, the residual metal in the mold is It is particularly important to perform quick cleaning. After the extrusion of the lead-tin alloy raw materials is completed, there will inevitably be residual raw materials in the mold. The existing cleaning methods are relatively simple. Most of them use manual operation to place the mold in an iron trough, soak it in a mold washing solution, make it react chemically with the metal material, and then take out the residual raw materials in the mold. However, the method of soaking in a mold washing solution has a long reaction time and low work efficiency. There are related solutions in the prior art to solve the above problems, such as a casting tube mold cleaning device with patent number CN112025509B, which places the tube mold in the placement tank, and the second servo motor provides power to drive the clamping claw module to move down to clamp the material. The stubborn attachments on the mold after soaking or the mold that is not suitable for soaking and cleaning are cleaned by a grinding module.

[0003] The prior art solves the problem of long chemical reaction time and low work efficiency when cleaning the residual raw materials in the mold with mold cleaning solution. The second servo motor provides power, and the first servo motor drives the rotating base to rotate, so that the clamping claw module moves into the soaking cylinder to move, thereby accelerating the cleaning of the mold with the mold cleaning solution. The stubborn attachments on the mold after soaking or the mold that is not suitable for soaking and cleaning are cleaned by the polishing module. Although the prior art accelerates the cleaning efficiency of the residual raw materials in the mold with the mold cleaning solution, the chemical reaction demolding is carried out by soaking the solution with the alloy raw material. After multiple soaking and polishing, the end face of the forming groove inside the mold is easily corroded by the solution, so that the surface of the finished product processed by the mold is not smooth, especially in the processing of semi-circular lead-tin anode plates with high requirements on surface roughness. The surface smoothness of the finished product will directly affect the uniformity of its conductivity during use, and the surface of the lead-tin alloy removed by soaking in the solution has undergone a chemical reaction and cannot be processed and used again, which is easy to cause waste of materials.

[0004] Therefore, a semicircular lead-tin anode extrusion forming die is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a semicircular lead-tin anode extrusion forming die.

[0015] In the above scheme, when the molding die moves to the left and drives the rising block to move to the left, the rising block can move upward along the rising guide groove. When the rising block moves upward, the rising block drives the unlocking block to move upward. While the unlocking block squeezes the unlocking spring, it drives the unlocking chamfer to be pulled out of the fixed groove. At this time, the end flat cover is separated from the molding die.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. After the existing mold is produced, it is often demoulded by soaking in liquid medicine. The demoulding time is long, and the frequent soaking in liquid medicine corrodes the film surface, so that the quality of the finished product cannot be guaranteed. The present invention arranges an inner locking component and a pushing component in the fixed mold. After the raw material is processed, the fixed mold and the feed mold are first fixed by the inner locking component, and the operator controls the outer locking ring to cooperate with the pushing component to directly push out the raw material remaining in the mold, which to a certain extent avoids the surface damage of the shaping groove when the raw material is taken out. After the remaining raw material is pushed out a certain distance, the fixed mold and the feed mold are automatically unlocked in cooperation with the inner locking component, which makes it more convenient to take out the residual raw material in the mold and improves work efficiency.

[0025] 2. The present invention sets a connecting component between the fixed mold and the feeding mold, making it more convenient and quick to disassemble and assemble the fixed mold and the feeding mold. A feeding groove is set in the feeding mold and a filling groove is set in the fixed mold, so that the raw material entering the shaping mold from the feeding mold is smoother and more stable.

[0026] 3. The present invention arranges an end flat component in the fixed mold so that the raw material entering the shaping mold contacts the end flat cover, and after the shaping groove is filled, the shaping mold is driven to move leftward until the shaping mold moves to the left end of the slide groove, and the end flat cover is automatically opened by the cover-removing unit. At the same time, the fixing between the fixed mold and the feeding mold is changed from being fixed by the connecting component to being fixed by the internal locking component, so that the outlet end face of the extruded lead-tin anode can be directly used without cutting or grinding, thereby reducing material waste.

[0043] See also Figure 4Specifically, the cover removal unit 74 includes an unlocking groove 741, an unlocking spring 742, an unlocking block 743, an unlocking chamfer 744, a rising guide groove 745 and a rising block 746.

The rising block 746 Set at the upper right end of the unlocking block 743, the rising block 746 cooperates with the rising guide groove 745. The cooperation here means that when the molding die 6 moves to the left and drives the rising block 746 to move to the left, the rising block 746 can move upward along the rising guide groove 745, and the unlocking chamfer 744 cooperates with the fixed groove 731. The cooperation here means that when the rising block 746 moves upward, the rising block 746 drives the unlocking block 743 to move upward. While the unlocking block 743 squeezes the unlocking spring 742, it drives the unlocking chamfer 744 to be pulled out from the fixed groove 731. At this time, the end flat cover 73 is separated from the molding die 6.

[0044] Working principle: When processing the lead-tin anode, the operator first fixes the feed die 3 and the fixed die 1 with the connecting component 2, and then places the connected feed die 3 and the fixed die 1 on the right side of the extruder. After the raw material is extruded into the shaping die 6, it is sealed and leveled by the end leveling component 7, and then the end leveling cover 73 is unlocked by the cover removal unit 74, so that the left end of the lead-tin anode after extrusion is flat and smooth, without cutting off the uneven part, reducing material waste.

[0045] Specifically, when the lead-tin anode is extruded, the operator first sleeves the feed die 3 on the right end of the fixed die 1, and then moves the outer locking ring 21, so that the outer locking ring 21 drives the outer locking block 24 to move to the left. When the outer locking block 24 moves to the left to the second outer locking groove 32, it is inserted into the inner locking groove 12 under the action of the outer locking spring 23, so that the fixed die 1, the feed die 3 and the outer locking ring 21 are fixed. After the fixed die 1 and the feed die 3 are fixed, the left side of the contraction section 312 of the feed trough 31 fits with the filling groove, and then the operator controls the extruder to extrude the lead-tin alloy in the fixed die 1. The lead-tin alloy is extruded from the feeding section 311 of the feed trough 31 into the contraction section 312, so that the metal alloy is initially contracted after being contracted by the contraction section 312, and then the metal alloy continues to move to the left, and is squeezed into the shaping groove 72 along the inlet groove 721 from the contraction section 312. The extruder continues to extrude the metal alloy until the metal The alloy fills the shaping groove 72 and is leveled by the end flat cover 73 and the inside of the shaping die 6. Then the metal alloy drives the end flat cover 73 and the shaping die 6 to move to the left. The shaping die 6 moves to the left, drives the reset ring 61 to extrude the end flat spring 71, and drives the unlocking block 743 to move to the left, and finally makes the left end of the reset ring 61 fit with the inner wall of the fixed die 1. During the fitting process, the rising block 746 at the upper end of the unlocking block 743 fits with the rising guide groove 745, and the rising block 746 moves upward along the rising guide groove 745. The rising block 746 moves upward and drives the unlocking block 743 to move upward. While the unlocking block 743 moves upward to extrude the unlocking spring 742, it drives the unlocking chamfer 744 to be pulled out of the fixed groove 731. At this time, the end flat cover 73 is separated from the shaping die 6, and the metal alloy in the shaping groove 72 is squeezed out from the left end, so that the left end of the lead-tin anode after extrusion is flat and smooth, and there is no need to cut off the uneven part, thereby reducing material waste.

[0046] Example 2

[0047] See also Figures 5 to 7, a semicircular lead-tin anode extrusion forming die is provided, including an inner locking component 5, the inner locking component 5 includes an inner locking block 51, an inner locking chamfer 52, an inner locking baffle 53 and an inner locking spring 54, a locking groove 7462 is arranged on the upper end of the rising block 746, the inner locking block 51 is slidably connected in the inner locking groove 12, the inner locking baffle 53 is fixed to the side of the inner locking block 51, the two ends of the inner locking spring 54 are respectively abutted against the upper end of the inner locking baffle 53 and the inner wall of the fixed mold 1, the inner locking chamfer 52 cooperates with the rising block 746, and the cooperation here means that when the rising block 746 moves upward along the rising guide groove 745, the inner locking block 51 can move along the rising block 746 to When the inner locking block 51 moves upward, the upper end of the inner locking block 51 cooperates with the outer locking block 24. The cooperation here means that when the inner locking block 51 moves upward, the inner locking block 51 can lift the outer locking block 24 upward, so that the lower end of the outer locking block 24 moves out of the second outer locking groove 32. The upper end of the inner locking block 51 cooperates with the second outer locking groove 32. The cooperation here means that after the inner locking block 51 pushes the outer locking block 24 out of the second outer locking groove 32, the inner locking block 51 is inserted into the second outer locking groove 32, and the lower end of the inner locking block 51 cooperates with the locking groove 7462. The cooperation here means that when the rising block 746 continues to move to the left after rising, the lower end of the inner locking block 51 can move into the locking groove 7462.

[0048] See also Figure 7 Specifically, a rising chamfer 7461 is provided at the upper left end of the rising block 746. The angle of the rising chamfer 7461 is greater than 45 degrees and less than 90 degrees, so that when the shaping mold 6 moves to the left, the rising block 746 is subjected to a greater force to unlock the end flat cover 73. The rising chamfer 7461 cooperates with the inner locking chamfer 52. The cooperation here means that when the rising block 746 drives the rising chamfer 7461 to move to the upper left along the rising guide groove 745, the rising chamfer 7461 is fitted with the inner locking chamfer 52, pushing the inner locking block 51 upward along the rising chamfer 7461 and squeezing the inner locking spring 54.

[0049] The rest of the structure is the same as that of Example 1.

[0050] Working principle: when the shaping mold 6 moves to the left and the end flat cover 73 is opened, the rising block 746 moves upward along the rising guide groove 745. When it moves to a certain distance, the rising chamfer 7461 fits with the inner locking chamfer 52. Since the angle of the rising chamfer 7461 is relatively steep, the resistance to the rising block 746 to the left becomes greater, which is conducive to the metal alloy being further compressed and flattened in the shaping groove 72. After the shaping mold 6 and the end flat cover 73 are subjected to a certain thrust, the shaping mold 6 drives the rising block 746 to continue to move to the left. At this time, the inner locking block 51 moves upward along the rising chamfer 7461. While the inner locking block 51 moves upward to squeeze the inner locking spring 54, the upper end of the inner locking block 51 pushes the outer locking block 24 upward, so that the outer locking block 24 squeezes the outer locking spring 23 and retracts into the first outer locking groove 22, until the lower end of the inner locking block 51 moves to the upper end of the rising block 746 The locking groove 7462, at this time, the end flat cover 73 is unlocked, the outer locking block 24 moves out of the second outer locking groove 32, and the upper end of the inner locking block 51 is inserted into the second outer locking groove 32, the fixed mold 1 and the feeding mold 3 are fixedly connected by the inner locking block 51, and the outer locking ring 21 is now released from the lock between the fixed mold 1 and the feeding mold 3, and the outer locking ring 21 can slide left and right on the feeding mold 3. After the extrusion is completed, the outer locking ring 21 can cooperate with the pushing component 4 to push out the residual material in the mold. The feeding mold 3 and the fixed mold 1 are quickly connected and fixed by the outer locking ring 21 when they are prepared for use. After use, they are fixed by the inner locking block 51, so that the feeding mold 3 cannot be unlocked during the extrusion process to prevent the fixed mold 1 and the feeding mold 3 from falling off during the extrusion process. The outer locking ring 21 cooperates with the pushing component 4 to demold the residual metal alloy in the mold, thereby achieving the stability of the mold use and having the effect of convenient demolding of the residual metal.

[0051] Example 3

[0052] See also Figures 8 to 9 , a semicircular lead-tin anode extrusion forming die is provided, including an ejection component 4, the ejection component 4 includes a limit groove 41, a limit block 42, an ejection ring 43 and a separation groove 44, the limit groove 41 is arranged on the outside of the feed die 3, the limit block 42 is arranged on the right end of the outer locking ring 21, the separation groove 44 is arranged on the right end of the limit groove 41, the ejection ring 43 is slidably connected in the separation groove 44, the ejection ring 43 is fixedly connected to the right end of the limit block 42, the right end of the separation groove 44 is connected to the feeding section 311, and the ejection ring 43 cooperates with the feeding section 311. The cooperation here means that when the outer locking ring 21 moves to the right and drives the ejection ring 43 to move to the right, the ejection ring 43 can extend into the feeding section 311.

[0053] The rest of the structure is the same as that of Example 2.

[0054] Working principle: After the extruder finishes extruding the metal raw material, the left end of the extruder is still some distance away from the right end of the contraction end, and the extruder retracts from the feeding section 311. The operator cuts the formed lead-tin anode at the left end of the shaping die 6, and waits for the residual metal in the shaping groove 72, the filling groove and the feeding groove 31 to cool and harden. The operator pushes the outer locking ring 21 to move the outer locking ring 21 to the right. The outer locking ring 21 moves to the right and drives the limit block 42 to move to the right along the limit groove 41. The block 42 moves rightward to drive the ejection ring 43 out of the separation groove 44, and the ejection ring 43 pushes the metal raw material in the feeding section 311 to move rightward, so that the ejection ring 43 cleans the residual metal in the mold. In the process of the outer locking ring 21 moving rightward, the lower end of the outer locking ring 21 first abuts against the upper end of the inner locking block 51, so that when the outer locking ring 21 drives the ejection ring 43 to just start to push the residual metal to the right, when the left end of the residual metal filled in the groove is just separated from the right end of the shaping mold 6, The upper end of the inner locking block 51 is still in contact with the lower end of the outer locking ring 21, and the inner locking block 51 cannot move upward along the locking groove 7462. The shaping mold 6 is still locked at the left end of the fixed mold 1, so that during the demoulding process, the inlet groove 721 at the right end of the shaping mold 6 does not contact the residual metal until the outer locking ring 21 drives the residual metal to move to the right to a certain distance, the residual metal is completely loosened, the upper end of the inner locking block 51 is out of contact with the lower end of the outer locking ring 21, and the inner locking block 51 can move upward along the locking groove 7462. Move, the end flat spring 71 resets and drives the shaping mold 6 to move to the right. After moving to a certain distance, the lower end of the inner locking block 51 is separated from the contact with the rising block 746, and the inner locking block 51 is reset under the action of the inner locking spring 54. The inner locking block 51 is separated from the cooperation with the second outer locking groove 32, and the fixed mold 1 and the feeding mold 3 are unlocked, which is convenient for subsequent maintenance and next use, and realizes rapid demoulding. At the same time, it reduces the contact between the shaping mold 6 and the residual metal to a certain extent, thereby increasing the service life of the mold.
