Description

Technical Field

[0001] The invention belongs to the technical field of nonferrous metal casting, in particular to a straight hole die for copper wire production. Background Art

[0002] Copper wire is drawn directly from hot-rolled copper rod without annealing and can be used for weaving mesh, making cables, and making copper brush filters. It comes in three varieties: brass, red copper, and phosphor copper. Due to its high electrical and thermal conductivity, it is widely used in the manufacture of electrical equipment and heat exchangers. It requires a straight-hole die to form it during production.

[0003] A patent with publication number CN220837861U discloses an injection mold, comprising a lower support, a bottom plate fixed above the lower support, a hydraulic cylinder fixed above the bottom plate, a hydraulic rod installed above the hydraulic cylinder, a top block fixed above the hydraulic rod, fixed columns fixed on both sides above the lower support, a mold base fixed above the fixed columns, a cooling mechanism provided inside the mold base, a straight hole tube installed above the mold base, and positioning columns fixed on both sides above the mold base; this is a straight hole mold for producing copper wire, which is used in conjunction with the hydraulic cylinder, hydraulic rod, top block and straight hole tube. After the copper wire in the straight hole tube is formed, the switch of the hydraulic cylinder is turned on to drive the hydraulic rod to extend and retract. Under the action of the hydraulic rod, the top block is pushed upward so that the formed copper wire can be directly ejected from the straight hole tube.

[0004] However, during the use of the existing straight hole mold for copper wire production, after the copper wire is ejected from the mold under the action of the hydraulic cylinder driving the top block, since the copper wire is cast from copper raw material, the copper raw material is prone to adhesion after contact with the metal top block. Even if the top block is coated with a release agent before production, in actual production, individual copper wires will still occasionally stick to the top block. Once the copper wire is stuck, staff need to manually demould it, which not only greatly increases the labor intensity of the staff, forcing them to always pay attention to the mold status and frequently perform demoulding operations, distracting their energy that could be used for other key production links, but also manual demoulding is inefficient, which will slow down the pace of the entire copper wire production and lead to an extension of the production cycle. In addition, during the manual demoulding process, if the operation is improper, it is easy to cause scratches, wear and other damages to the surface of the copper wire, reducing the product quality of the copper wire and increasing the scrap rate.

[0005] To this end, the present invention provides a straight hole die for copper wire production. Summary of the Invention

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example 1: Figures 1 to 6 As shown, a straight hole die for copper wire production described in an embodiment of the present invention includes a bottom plate, a support frame is fixedly connected to the upper surface of the bottom plate, a top plate is fixedly connected to the top of the support frame, a plurality of mold holes are opened on the upper surface of the top plate, a middle partition is fixedly connected to the middle of the support frame, a fixed tube is fixedly connected to the upper surface of the middle partition, a plurality of hydraulic cylinders are fixedly connected to the position of the bottom plate corresponding to the fixed tube, a cooling tube is arranged inside the middle partition, demoulding components are arranged on both sides of the top plate, the demoulding components include fixed frames fixedly connected to both sides of the machine body, a rotating plate is rotatably connected to the middle of the fixed frame, a limit plate is fixedly connected to one side of the fixed frame, and the limit plate One end of the rotating plate is fixedly connected to a connecting plate, one side of the connecting plate is fixedly connected to a reciprocating screw, the circumferential surface of the reciprocating screw is slidably connected to a slider, one side of the slider is fixedly connected to an inserting plate, and one end of the inserting plate is fixedly connected to a cutter; a fixed groove is opened inside the rotating plate, and a gear is rotatably connected inside the fixed groove. The middle of the gear is fixedly connected to a connecting shaft, and one end of the connecting shaft is fixedly connected to a rectangular rod, which is driven by a built-in electric push rod arranged inside the connecting shaft. The rectangular rod can be plugged into a rectangular hole opened at one end of the reciprocating screw, and the gear is meshed with a rack plate, one end of the rack plate is fixedly connected to a cross bar, and one end of the cross bar is rotatably connected to an auxiliary disk.

[0032] Specifically, in the use of the existing straight hole mold for copper wire production, when the copper wire is ejected from the mold under the action of the hydraulic cylinder driving the ejector block, since the copper wire is cast from copper raw material, the copper raw material is prone to adhesion after contact with the metal ejector block. Even if the ejector block is coated with a release agent before production, in actual production, individual copper wires may still occasionally stick to the ejector block. Once the copper wire sticks, a worker needs to manually demould it, which not only greatly increases the labor intensity of the workers, but also forces them to pay attention to the mold status at all times and perform demoulding operations frequently, distracting their energy that could be used for other key production links. In addition, the manual demoulding is inefficient, which slows down the pace of the entire copper wire production and prolongs the production cycle. In addition, during the manual demoulding process, if the operation is improper, it is easy to cause scratches, wear and other damages to the surface of the copper wire, thereby reducing the product quality of the copper wire and increasing the scrap rate.

[0033] Therefore, the present invention sets the above structure to solve the above problem. First, the copper raw material is injected into the mold hole on the upper surface of the top plate. Then, after cooling through the cooling tube, the motor is started to drive the rotating plate to cover the mold hole on the upper surface of the top plate.

[0034] The hydraulic cylinder is started again to drive the cooled copper wire to be jacked up. During the jacking process, the copper wire is jacked up row by row. When the last row of copper wires pushes the auxiliary plate to move upward, the upward movement of the auxiliary plate drives the rack plate to move upward, and the rack plate drives the gear to rotate. The rotation of the gear drives the rectangular rod indirectly fixed to it to rotate, and the rotation of the rectangular rod drives the reciprocating screw plugged with it to rotate. The rotation of the reciprocating screw drives the plug plate sliding on its circumferential surface, and the plug plate will slide along the reciprocating screw and be inserted into the auxiliary groove opened on the lower surface of the rotating plate. The cutter at the end of the plug plate will separate the copper wire and the top of the hydraulic cylinder, separating the copper wire row by row, thereby completing demoulding. During the separation process, since the cutter is inclined, it will also lift the copper wire a short distance, thereby performing longitudinal demoulding work, solving the problem of the copper wire sticking to the top block of the hydraulic cylinder, improving demoulding efficiency, thereby increasing production volume, and avoiding the risks brought by manual demoulding.

[0035] like Figure 4 As shown, in this embodiment, one end of the crossbar is fixedly connected to two fixed blocks, a fixed shaft is fixedly connected between the two fixed blocks, a torsion spring is sleeved on the circumferential surface of the fixed shaft, and the auxiliary disk is fixedly connected to the torsion spring.

[0036] Specifically, the copper wire is pushed, and in the process of lifting the auxiliary plate to drive the rack plate to move, the pushing force cannot cause the torsion spring to twist and rotate. When the rotating plate rotates to both sides of the top plate to unload the material, the weight of the copper wire itself will cause the torsion spring to twist, and then the auxiliary plate will rotate, causing the copper wire to fall off automatically.

[0037] When the copper wire lifts the auxiliary disk to drive the rack plate to move, the thrust will not cause the torsion spring to rotate, ensuring the stability of the structure and the accuracy of the movement at this stage. When unloading, the copper wire's own gravity can cause the torsion spring to twist, driving the auxiliary disk to rotate and allowing the copper wire to fall off automatically. No additional power source is required, realizing automatic unloading, improving production efficiency, reducing manual intervention costs, and enhancing the reliability and practicality of the overall device.

[0038] like Figure 3 As shown, a fixed cavity is opened inside the rotating plate of this embodiment, a fixed plate is fixedly connected to the middle of the fixed cavity, positioning push rods are fixedly connected on both sides of the inner wall of the fixed cavity, the positioning push rods are electric rods, one end of the positioning push rods is fixedly connected to a limiting clamp, and limiting clamps are also provided on both sides of the fixed plate.

[0039] Specifically, when the copper wires are fully lifted up, each positioning push rod is started to drive the limit clamp at one end thereof to clamp the copper wire. During the rotation of the rotating plate, the copper wire is clamped, and when it is perpendicular to the ground, the limit clamp is retracted to complete the unloading work. By starting the positioning push rod after the copper wires are fully lifted up and using the limit clamp to accurately clamp the copper wires, the position of the copper wires can be ensured to be stable when the rotating plate rotates, avoiding shaking, displacement or even falling off, thereby ensuring the safety of operation.

[0040] like Figure 4 As shown, one end of the rack plate of this embodiment is fixedly connected to the chassis, which is a counterweight plate. After the unloading work is completed and the next group of copper wires are cooled, the motor drives the rotating plate to rotate again through the rotating shaft fixed to its output end to cover the upper surface of the top plate. Under the action of gravity, the chassis drives the rack plate to move downward, and the rack plate can then drive the insert plate to disengage from the auxiliary groove opened on the rotating side, so as to carry out the next demolding work.

[0041] Specifically, after the unloading is completed and the next group of copper wires are cooled, the motor drives the rotating shaft connected to the output end, driving the rotating plate to rotate again and cover the upper surface of the top plate. At this time, the chassis at one end of the rack plate acts as a counterweight plate, which generates a downward pulling force under the action of gravity, driving the rack plate to move downward. During the movement of the rack plate, it will drive the associated plug plate to disengage the plug plate from the auxiliary groove opened on one side of the rotating plate, preparing for subsequent demoulding work;

[0042] The gravity of the chassis is used to automatically drive the rack plate and the insert plate, without the need for additional complex drive devices, which simplifies the structure and reduces costs. At the same time, the entire process is automatically connected, and when the rotating plate is reset, it can simultaneously create conditions for demoulding, thereby improving the continuity and automation of the production process, effectively improving production efficiency, and reducing manual operation and waiting time.

[0043] Example 2: Figures 1 to 6 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a storage box is fixedly connected to one side of the slider, and a plurality of annular grooves are opened on the lower surface of the insert plate. When the demoulding is completed, the rotating plate can be started again to cover the top plate, and the pressure pump in the storage box can be started to inject the release agent in the storage box along the annular groove. After the injection is completed, the rotation is started again to rotate to both sides to carry out the copper raw material filling work.

[0044] Specifically, a storage box is provided on one side of the slider, and a plurality of annular grooves are provided on the lower surface of the insert plate. After the demoulding is completed, the rotating plate is first allowed to cover the top plate, and then the pressure pump in the storage box is started. Under the action of pressure, the release agent in the storage box will be injected along the annular groove on the lower surface of the insert plate. After the injection of the release agent is completed, the rotating plate is started to rotate to both sides to make room, and then the copper raw material can be added to prepare for the next production; the injection of the release agent is accurately guided by the annular groove to ensure uniform coating and improve the demoulding effect. Injection when the rotating plate covers the top plate can effectively avoid splashing and waste of the release agent, and the whole process is coherent. Copper raw material can be added after injection, which improves production efficiency.

[0045] like Figure 5 As shown, the upper surface of the limiting plate of this embodiment is provided with a limiting groove, and the lower surface of the slider is fixed with an auxiliary block that slides along the limiting groove, thereby assisting the slider to slide and demould along the reciprocating screw.

[0046] Specifically, the upper surface of the limit plate is provided with a limit groove, into which the auxiliary block on the lower surface of the slider is embedded. When the reciprocating screw rotates, the auxiliary block is restricted by the limit groove and cannot rotate with the screw. It can only move linearly along the limit groove, thereby driving the slider to slide linearly along the reciprocating screw, achieving precise movement of the slider during the demolding process and completing the demolding work.

[0047] Working principle: First, copper raw material is injected into the mold hole on the upper surface of the top plate. Then, after cooling down in the cooling tube, the motor is started to drive the rotating plate to cover the mold hole on the upper surface of the top plate.

[0048] The hydraulic cylinder is started again to drive the cooled copper wire to be jacked up. During the jacking process, the copper wire is jacked up row by row. When the last row of copper wires pushes the auxiliary plate to move upward, the upward movement of the auxiliary plate drives the rack plate to move upward, and the rack plate drives the gear to rotate. The rotation of the gear drives the rectangular rod indirectly fixed to it to rotate, and the rotation of the rectangular rod drives the reciprocating screw plugged with it to rotate. The rotation of the reciprocating screw drives the insert plate set on its circumferential surface to slide along the reciprocating screw, thereby inserting into the auxiliary groove opened on the lower surface of the rotating plate, and the cutter at the end of the insert plate separates the copper wire and the top of the hydraulic cylinder, separating the copper wire row by row, thereby completing demoulding. During the separation process, since the cutter is inclined, it will also jack up the copper wire for a short distance, thereby performing longitudinal demoulding work, solving the problem of the copper wire sticking to the top block of the hydraulic cylinder, improving demoulding efficiency, thereby increasing production volume, and avoiding the risks brought by manual demoulding;

[0049] In addition, when the copper wire is pushed and the auxiliary plate is lifted to drive the rack plate to move, the pushing force cannot cause the torsion spring to twist and rotate. When the rotating plate rotates to both sides of the top plate to unload the material, the weight of the copper wire itself will cause the torsion spring to twist, thereby causing the auxiliary plate to rotate, causing the copper wire to fall off automatically.

[0050] When the copper wire lifts the auxiliary disk to drive the rack plate to move, the thrust will not cause the torsion spring to rotate, ensuring the stability of the structure and the accuracy of the action at this stage. When unloading, the copper wire's own gravity can twist the torsion spring, driving the auxiliary disk to rotate and let the copper wire fall off automatically. No additional power source is required, realizing automatic unloading, improving production efficiency, reducing manual intervention costs, and enhancing the reliability and practicality of the entire device.

[0051] And when the copper wires are fully lifted up, each positioning push rod is started to drive the limit clamp at one end thereof to clamp the copper wires. During the rotation of the rotating plate, the copper wires are clamped. When the copper wires are perpendicular to the ground, the limit clamps are retracted to complete the unloading work. By starting the positioning push rod after the copper wires are fully lifted up and using the limit clamps to accurately clamp the copper wires, the position of the copper wires can be ensured to be stable when the rotating plate rotates, avoiding shaking, displacement or even falling off, thereby ensuring the safety of the operation.

[0052] In addition, a storage box is provided on one side of the slider, and a number of annular grooves are provided on the lower surface of the insert plate. After demoulding is completed, the rotating plate is first allowed to cover the top plate, and then the pressure pump in the storage box is started. Under the action of pressure, the release agent in the storage box will be injected along the annular grooves on the lower surface of the insert plate. After the injection of the release agent is completed, the rotating plate is started to rotate to both sides to make room, and then the copper raw material can be added to prepare for the next production. The injection of the release agent is precisely guided by the annular grooves to ensure uniform application and improve the demoulding effect. Injection when the rotating plate covers the top plate can effectively avoid splashing and waste of release agent, and the entire process is coherent. Copper raw material can be added after injection, which improves production efficiency.

[0053] Finally, after the unloading is completed and the next group of copper wires have cooled, the motor drives the rotating shaft connected to the output end, driving the rotating plate to rotate again and cover the upper surface of the top plate. At this time, the chassis at one end of the rack plate acts as a counterweight plate, generating a downward pulling force under the action of gravity, driving the rack plate to move downward. During the movement of the rack plate, it will drive the associated plug plate to disengage the plug plate from the auxiliary groove opened on one side of the rotating plate, preparing for the subsequent demoulding work;

[0054] The gravity of the chassis is used to automatically drive the rack plate and the insert plate, without the need for additional complex drive devices, which simplifies the structure and reduces costs. At the same time, the entire process is automatically connected, and when the rotating plate is reset, it can simultaneously create conditions for demoulding, thereby improving the continuity and automation of the production process, effectively improving production efficiency, and reducing manual operation and waiting time.

After the unloading work is completed and the next group of copper wires are cooled, the motor (27) drives the rotating plate (21) to rotate again through the rotating shaft (28) fixedly connected to its output end to cover the upper surface of the top plate (13). The chassis (211) drives the rack plate (210) to move downward under the action of gravity, and the rack plate (210) can then drive the insert plate (3) to disengage from the auxiliary groove (22) opened on the rotating side, thereby performing the next demoulding work.

7. The straight hole die for copper wire production according to claim 1, characterized in that: A limiting groove (38) is provided on the upper surface of the limiting plate (31), and an auxiliary block (37) is fixedly connected to the lower surface of the slider (34) to slide along the limiting groove (38), thereby assisting the slider (34) to slide and demould along the reciprocating screw (33).

8. The straight hole die for copper wire production according to claim 1, characterized in that: A storage box (36) is fixedly connected to one side of the slider (34), and a plurality of annular grooves (39) are opened on the lower surface of the inserting plate (3). When the demoulding is completed, the rotating plate (21) can be started again to cover the top plate (13), and the pressure pump in the storage box (36) is started to inject the demoulding agent in the storage box (36) along the annular groove (39). After the injection is completed, the rotating plate (21) is started again to rotate to both sides to carry out the copper raw material filling work.
