[0001] The application relates to the technical field of mold separators, in particular to a multi-row wire mold separator. BACKGROUND

[0002] At present, in the technical field of cable processing, the disassembly and replacement of a multi-row wire mold is an indispensable link in the production process.

[0003] In the production process of the insulating core of a cross-linked polyethylene insulated power cable and a rubber insulated power cable, a mold needs to be installed on an extrusion head, the mold comprises a mold core and a mold sleeve, the mold sleeve is connected with the extrusion head, the mold core is usually in the shape of a sharp cone, the conical surface of the mold core is embedded in the mold sleeve, and reference can be made to the patent with the announcement number CN222168045U. In actual production, the end of the mold core away from the mold sleeve is protruded from the mold sleeve, that is, located outside the mold sleeve, and the two are only embedded.

[0004] In the process of replacing the mold sleeve, manual operation is often relied on, tools need to be used to take out the mold core with force, and physical damage to the mold core also needs to be reduced, and there is the defect that the replacement of the mold core is inconvenient. CONTENT OF THE UTILITY MODEL

[0005] In order to reduce the dependence on manual operation, improve the convenience of replacing the mold core and reduce the physical damage to the mold core, the application provides a multi-row wire mold separator.

[0006] The multi-row wire mold separator provided by the application adopts the following technical scheme:

[0007] The multi-row wire mold separator comprises a base fixed beside a mold sleeve, a carrier plate is slidably arranged on the base and slides along the direction of approaching or moving away from the mold sleeve; a left clamping plate and a right clamping plate are slidably arranged on the carrier plate and slide along the direction of approaching or moving away from each other; a first screw rod is rotatably arranged on the carrier plate, the first screw rod penetrates through the left clamping plate and the right clamping plate and is threadedly connected with the two, the first screw rod has opposite screw rotation directions on the two sides of the midpoint of the first screw rod as a boundary line, a first sliding groove is formed on the carrier plate along the direction of the line connecting the left clamping plate and the right clamping plate, and the left clamping plate and the right clamping plate are inserted and slidably arranged in the first sliding groove at the end close to the carrier plate; rubber pads are fixed on the mutually opposite side walls of the left clamping plate and the right clamping plate; and a power assembly for driving the carrier plate to move is arranged on the base.

[0008] By adopting the technical scheme, when the mold core of the multi-row wire mold is replaced, the power assembly is started, the motor is operated to drive the gear to rotate, and since the gear is engaged with the rack, the carrier plate will slide on the base in the direction close to the mold sleeve. After the carrier plate moves to the appropriate position, the first screw is rotated, since the thread rotation directions of the screw on both sides of the midpoint are opposite, the left clamping plate and the right clamping plate will slide in the first sliding groove in the direction close to each other, so that the left clamping plate and the right clamping plate clamp the part of the mold core protruding from the mold sleeve, and the rubber pad can increase the friction and protect the surface of the mold core from being clamped. Then the power assembly is started again, and the carrier plate drives the clamped mold core to slide away from the mold sleeve, so that the mold core is easily pulled out of the mold sleeve, the whole process reduces the dependence on manual operation, improves the convenience of mold core replacement, and effectively reduces the physical damage to the mold core.

[0009] Optionally, two first suction cups are slidably arranged on the side wall of the left clamping plate opposite to the right clamping plate, and the two first suction cups slide in the vertical direction in the direction close to or away from each other; a second suction cup is arranged on the side wall of the right clamping plate opposite to the left clamping plate, and the second suction cup is located at the center of the right clamping plate.

[0010] By adopting the technical scheme, before the left clamping plate and the right clamping plate clamp the mold core, the positions of the two first suction cups in the vertical direction can be adjusted according to the shape and size of the mold core, so that the first suction cup and the second suction cup can better fit the surface of the mold core. The suction cup adsorbs the mold core, further increases the fixing effect of the mold core, prevents the mold core from shaking or falling during the pulling out process, improves the stability and safety of the operation, and helps to more stably separate the mold core from the mold sleeve.

[0011] Optionally, the second suction cup is ball-jointed with the right clamping plate.

[0012] By adopting the technical scheme, the second suction cup can rotate flexibly in all directions, no matter how irregular the surface shape of the mold core is, the second suction cup can automatically adjust the angle to realize close fitting with the surface of the mold core, thereby enhancing the adsorption force, ensuring the reliability of the fixation of the mold core, further improving the stability during the separation process of the mold core, and reducing the risk of shaking or falling of the mold core due to poor fitting of the suction cup with the mold core.

[0013] Optionally, a second sliding groove is formed in the vertical direction on the side wall of the left clamping plate opposite to the right clamping plate, both ends of the two first suction cups are inserted and slidably arranged in the second sliding groove, and the first suction cup slides along the length direction of the second sliding groove; a second screw is rotatably arranged on the left clamping plate, the second screw penetrates through the two first suction cups and is threadedly connected with the first suction cups, and the thread rotation directions of the second screw on both sides of the midpoint are opposite.

[0014] By adopting the technical scheme, when the second screw is rotated, the two first suction cups are driven to move closer to or away from each other in the vertical direction in the second sliding groove due to the opposite screw thread directions on the two sides of the second screw. The operator can accurately adjust the position of the first suction cup according to the actual size of the mold core, so that the contact between the suction cup and the mold core is more fitted, the operation is simple and convenient, the adjustment accuracy is high, the adaptability of the device to mold cores of different specifications is greatly improved, and the mold core can be stably fixed in various cases, facilitating subsequent separation operation.

[0015] Optionally, the carrier plate is provided with an air pump and an air suction pipe. The air pump is fixed on the carrier plate. One end of the air suction pipe is communicated with the air pump, and the other end penetrates through the left clamping plate and extends into the second sliding groove and penetrates into the first suction cup. An air suction passage is formed in the first suction cup, and the opening end of the air suction passage is arranged to face the right clamping plate. Two air suction pipes are arranged corresponding to the number of the first suction cups.

[0016] By adopting the technical scheme, after the air pump is started, the air pump draws air in the first suction cup through the air suction pipe, so that a negative pressure is formed in the first suction cup, and the first suction cup is tightly adsorbed on the surface of the mold core. Compared with simply relying on mechanical clamping, the suction cup adsorption increases the way of fixing the mold core, further improves the fixing effect of the mold core, effectively prevents the displacement or loosening of the mold core in the separation process, ensures the smooth separation of the mold core from the mold sleeve, and reduces the possibility of damage to the mold core caused by excessive mechanical clamping force.

[0017] Optionally, a threading pipe is fixed on the left clamping plate. One end of the threading pipe is communicated with the outside, and the other end penetrates into the second sliding groove. The two air suction pipes pass through the threading pipe. Wire clamps are fixed on the two air suction pipes, and the wire clamps are located on the side of the left clamping plate away from the right clamping plate.

[0018] By adopting the technical scheme, the threading pipe plays a protective and guiding role on the air suction pipe, preventing the air suction pipe from being damaged by external force pulling or extrusion during the operation of the device, and ensuring that the air connection between the air pump and the first suction cup is stable and reliable.

[0019] Optionally, a distance exists between the wire clamp and the air suction pipe. A spring is arranged between the wire clamp and the air suction pipe. One end of the spring is fixedly connected with the end of the air suction pipe, and the other end is abutted with the wire clamp.

[0020] By adopting the technical scheme, when the two first suction cups move towards each other, the air suction pipes in the second sliding groove may be stacked. At this time, the spring pushes the wire clamp to move away from the threading pipe, and the wire clamp drives the air suction pipe to separate from the second sliding groove, avoiding the stacking of the air suction pipes in the second sliding groove, and ensuring the smooth use of the air suction pipes.

[0021] Optionally, the power assembly comprises a motor, a gear and a rack, the rack is embedded and fixed on the top surface of the base, the length direction of the rack is arranged along the sliding direction of the carrier plate, the motor is fixed on the outer wall of the carrier plate, the output end of the motor is fixed with the center of the gear, and the gear is engaged with the rack.

[0022] By adopting the above technical scheme, the motor serves as a power source, and after being started, the output shaft of the motor drives the gear to rotate. Since the gear is engaged with the rack and the rack is fixed on the base, according to the transmission principle of the gear and the rack, the carrier plate will slide on the base along the length direction of the rack, that is, in the direction close to or away from the mold sleeve.

[0023] To sum up, the present application has at least one of the following beneficial technical effects:

[0024] 1.

[0032] The application discloses a multi-row wire mold separator.

[0033] Reference Figure 1 A multi-row wire mold separator comprises a base 1 which is firmly fixed at a suitable position close to a mold sleeve. The base 1 needs to have sufficient stability to bear various acting forces in subsequent operation processes. On the base 1, a carrier plate 2 which can slide towards or away from the mold sleeve is installed. On the carrier plate 2, oppositely arranged left and right clamping plates 21 and 22 are installed, which can slide towards or away from each other. A first sliding groove 24 is formed on the carrier plate 2 along the direction of the line connecting the left and right clamping plates 21 and 22. The left and right clamping plates 21 and 22 are inserted and slidably arranged in the first sliding groove 24 at one end close to the carrier plate 2, so that the sliding direction of the clamping plates can be accurately controlled. A first screw rod 23 is rotatably arranged on the carrier plate 2, penetrates through the left and right clamping plates 21 and 22 and is threadedly connected with the left and right clamping plates 21 and 22. The first screw rod 23 has opposite screw directions on the two sides of the midpoint thereof. When an operator rotates the first screw rod 23, the left and right clamping plates 21 and 22 will synchronously slide towards the middle or to the two sides in the first sliding groove 24. Rubber pads 3 are fixed on the side walls of the left and right clamping plates 21 and 22 which face each other. The rubber pads 3 are made of soft rubber material with high friction, such as nitrile rubber. The rubber pads 3 can increase the friction force to prevent the mold core from falling off and protect the surface of the mold core from being damaged when the mold core is clamped.

[0034] Reference Figure 1 And Figure 2 A power assembly 4 is arranged on the base 1. The power assembly 4 comprises a motor 41, a gear 42 and a rack 43. The rack 43 is fixedly embedded on the top surface of the base 1, and the length direction of the rack 43 is arranged along the sliding direction of the carrier plate 2, that is, the direction of approaching or moving away from the mold sleeve. The motor 41 is fixed on the vertical outer wall of the carrier plate 2, and the output end of the motor 41 is fixedly connected with the center of the gear 42. The gear 42 is engaged with the rack 43. The motor 41 is an alternating current motor which has stable rotating speed and sufficient torque. By reversing the motor 41, the gear 42 is driven to roll on the rack 43, so that the carrier plate 2 can stably approach or move away from the mold sleeve on the base 1.

[0035] Reference Figure 1 And Figure 2Two first suction cups 5 are slidingly arranged on the side wall of the left clamping plate 21 opposite to the right clamping plate 22, and slide in the direction of approaching or moving away from each other in the vertical direction. A second sliding groove 211 is formed in the vertical direction on the side wall of the left clamping plate 21 opposite to the right clamping plate 22, and the end of each of the two first suction cups 5 is inserted and slidingly arranged in the second sliding groove 211, and the first suction cup 5 slides along the length direction of the second sliding groove 211. A second screw 212 is rotatably arranged on the left clamping plate 21, and the second screw 212 is vertically arranged and penetrates through the two first suction cups 5 and is threadedly connected with the first suction cups 5, and the second screw 212 has opposite screw thread directions on both sides of the midpoint thereof. By rotating the second screw 212, the operator can accurately adjust the distance between the two first suction cups 5 in the vertical direction to adapt to the mold cores of different diameters.

[0036] Referring to Figure 2 A second suction cup 6 is arranged at the center of the side wall of the right clamping plate 22 opposite to the left clamping plate 21 by means of a ball hinge. The ball hinge can flexibly rotate in various directions, ensuring that the second suction cup 6 can adapt to the surface of the mold core of different shapes.

[0037] Referring to Figure 2 And Figure 3 A gas pump 25 is fixed on the carrier plate 2, and the gas pump 25 is selected to be a small-sized and high-negative-pressure vacuum pump to meet the requirement of quickly forming negative pressure in the suction cup. An air suction pipe 26 is arranged between the gas pump 25 and the first suction cup 5. One end of the air suction pipe 26 is in communication with the gas pump 25, and the other end penetrates through the left clamping plate 21 into the second sliding groove 211 and penetrates into the first suction cup 5. An air suction passage is formed in the first suction cup 5, and the opening end of the air suction passage is arranged to face the right clamping plate 22. Two air suction pipes 26 are arranged corresponding to the number of the first suction cups 5, to ensure that the two first suction cups 5 can independently and stably form negative pressure adsorption of the mold core.

[0038] Referring to Figure 2 And Figure 3The threading pipe 7 is fixed on the left clamping plate 21, one end of the threading pipe 7 is communicated with the outside, the other end penetrates into the second sliding groove 211, and the two air suction pipes 26 penetrate through the threading pipe 7.

The spring 9 is selected to be a compression spring with a proper elastic coefficient. When the two first suction cups 5 move in the direction of approaching each other, the air suction pipe 26 has a tendency to accumulate in the second sliding groove 211, at this time, the spring 9 pushes the wire clamp 8 to move away from the threading pipe 7 in the direction, the wire clamp 8 drives the air suction pipe 26 to separate from the second sliding groove 211, effectively avoiding the accumulation of the air suction pipe 26 in the second sliding groove 211, and ensuring the smooth use of the air suction pipe 26.

[0039] The implementation principle of the multi-wire mold separator in the embodiment of the present application is as follows: when the mold core of the multi-wire mold needs to be replaced, the motor 41 in the power assembly 4 is started, the motor 41 is rotated in the positive direction, the output shaft of the motor 41 drives the gear 42 to rotate, and since the gear 42 is engaged with the rack 43, the carrier plate 2 slides on the base 1 in the direction of approaching the mold sleeve. The operator closely observes the moving position of the carrier plate 2, and when the carrier plate 2 moves to the appropriate position, so that the left clamping plate 21 and the right clamping plate 22 can be aligned with the part of the mold core protruding from the mold sleeve, the operation of the motor 41 is stopped. The operator rotates the first screw 23, and the left clamping plate 21 and the right clamping plate 22 slide in the first sliding groove 24 in the direction of approaching each other, gradually clamping the part of the mold core protruding from the mold sleeve, and the air pump 25 is started. The air pump 25 sucks the air in the first suction cup 5 through the air suction pipe 26, so that the negative pressure is formed in the first suction cup 5, the first suction cup 5 is tightly adsorbed on the surface of the mold core, and the fixing effect on the mold core is further increased. The motor 41 is started again, the motor 41 is reversed, and the carrier plate 2 drives the clamped and tightly adsorbed mold core to slide away from the mold sleeve, so that the mold core is easily pulled out of the mold sleeve. During the whole process, the second suction cup 6 automatically adjusts the angle through the ball hinge, and is always closely combined with the surface of the mold core, so that the mold core does not shake or slip. The pulled-out mold core is placed in the designated position, and subsequent cleaning, maintenance or replacement operations are performed. If a new mold core needs to be installed, the new mold core is accurately installed into the mold sleeve according to the reverse operation steps.
