Description

Technical Field

[0001] The present application relates to the technical field of cable production, and in particular to a molding device for preventing abnormal movement of a vacuum mold. Background Art

[0002] In recent years, with the improvement of living standards, the construction industry has gradually increased its requirements for product quality and safety. The requirements for wire and cable products have also increased. During the construction and laying process, the tensile strength of the cables has increased. The specific reason is that during the cable manufacturing process, the cables are wrapped on the outside of the cables through a compression mold, and the conductor passes through the compression mold, which increases the tensile strength of the cables.

[0003] At present, when the compression mold originally used for cables is replaced with a non-compression mold, the tensile strength of the cables can be reduced. However, when a non-compression mold is used, the distance between the base plastic and the conductor surface is easily increased. In view of the above-mentioned existing technical problems, the non-compression mold is combined with the vacuum equipment at the head position, so that the product production effect can achieve the characteristics of the compression mold, and can ensure that the product does not destroy the close adhesion of fire-resistant wires and cables, and finally achieve an increase in the tensile strength of the product. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a molding device that prevents abnormal movement of a vacuum mold, and has the advantages of reducing the increase in product tensile strength.

[0006] The connection structure comprises a hook member arranged outside the flow divider and a bending plate fixedly mounted on one end of the vacuum box facing the extruder.

[0007] Furthermore, the extrusion die comprises a porous plate fixed to the extrusion end of the extruder through a flange frame, a flow divider threadedly assembled on the porous plate, and a die threadedly assembled on the outside of the flow divider.

[0008] Furthermore, a core rod is integrally extended from the middle of the flow divider to facilitate the conductor to pass through, and a cone is installed on the external thread of the core rod, and the cone is conical.

[0009] Furthermore, the hook member includes a bending rod with an L-shaped end and a threaded rod threadedly connected to the bending rod, and one end of the bending rod extends to the inner side of the bending plate and is interlocked with the bending plate.

[0010] Furthermore, a nut is fixedly mounted on the outside of the threaded rod.

[0011] Furthermore, there are two bending plates in total, and the two bending plates are arranged in opposite directions. A joint pipe is slidably installed between the two bending plates, and a groove corresponding to the thickness of the bending plate is opened on the outer wall of the joint pipe.

[0012] Furthermore, a slide groove for the joint pipe to move up and down is provided on a side surface of the vacuum box facing the extruder, and one end of the joint pipe passes through the slide groove and extends to the interior of the vacuum box.

[0013] Furthermore, a sealing plate is fixedly mounted on one end of the joint pipe extending into the vacuum box and is attached to the inner wall of the vacuum box, and the size of the sealing plate is larger than the width of the slide groove.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The molding device for preventing the abnormal movement of the vacuum mold replaces the original pressing mold with a non-pressing mold and adopts a vacuum box vacuum connection method to eliminate the gap between the conductor and the cable caused by the non-pressing mold, thereby avoiding the phenomenon of increased tensile strength of the cable caused by the original mold.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-4 A molding device for preventing abnormal movement of a vacuum mold in this embodiment includes an extruder 1 for extrusion molding and an extrusion mold connected to the extrusion end of the extruder 1, and a vacuum box 8 for vacuuming is connected to one end of the extrusion mold.

[0023] In the present application, by sending the plastic and the conductor extruded by the extruder 1 into the vacuum box 8 for vacuum treatment, the fit between the cable produced by the non-pressing mold and the conductor can be improved, and the tensile strength of the cable can be reduced.

[0024] In this embodiment, the extrusion die includes a porous plate 3 fixed to the extrusion end of the extruder 1 through a flange frame 2, a flow divider 4 threadedly assembled on the porous plate 3, and a die 7 threadedly assembled on the outside of the flow divider 4;

[0025] Furthermore, a core rod 5 is integrally extended from the middle of the flow divider 4 to facilitate the passage of the conductor, and a cone 6 is installed on the external thread of the core rod 5. The cone 6 is conical in shape, so that the extruded plastic can fit the outside of the conductor along the conical surface outside the cone 6 and complete the extrusion coating through the opening at the end of the die 7.

[0026] It should be noted that a connection structure for connecting the die 7 and the vacuum box 8 is provided outside the flow divider 4, and the connection structure includes a hook member provided outside the flow divider 4 and a bending plate 9 fixedly installed on one end of the vacuum box 8 facing the extruder 1.

[0027] The hook member in this embodiment includes a bending rod 13 with an L-shaped end and a threaded rod 12 threadedly connected to the bending rod 13 . One end of the bending rod 13 extends to the inner side of the bending plate 9 and is interlocked with the bending plate 9 .

[0028] Through the connection of the bending rod 13 , the bending plate 9 and the vacuum box 8 can be brought close to the extruder 1 for docking by pulling the bending rod 13 .

[0029] In this embodiment, a nut 14 is fixedly mounted on the outside of the threaded rod 12 , and the nut 14 can be used to conveniently use a tool to pull the threaded rod 12 for rotation.

[0030] In the present application, four bending rods 13 are provided to connect the vacuum box 8 and the die 7 to each other, thereby reducing the abnormal movement of the vacuum die, that is, the vacuum box 8 connected to the extruder.

[0031] It should be noted that there are two bending plates 9, and the two bending plates 9 are arranged in opposite directions. A joint pipe 10 is slidably installed between the two bending plates 9, and a groove corresponding to the thickness of the bending plate 9 is opened on the outer wall of the joint pipe 10 to facilitate the joint pipe 10 to slide up and down relative to the bending plate 9 to change its position.

[0032] In this embodiment, a chute is provided on one side of the vacuum box 8 facing the extruder 1 for the joint pipe 10 to move up and down, and one end of the joint pipe 10 passes through the chute and extends to the inside of the vacuum box 8;

[0033] Furthermore, a sealing plate 11 is fixedly installed on one end of the joint pipe 10 extending into the vacuum box 8 and is in contact with the inner wall of the vacuum box 8. The size of the sealing plate 11 is larger than the width of the slide groove, so that when the joint pipe 10 slides up and down relative to the vacuum box 8, the sealing plate 11 can be tightly attached to the inner wall of the vacuum box 8, so that the vacuum box 8 is completely closed.

[0034] It should be noted that the sealing plate 11 is attached to one side of the vacuum box 8 and sealing material can be added to improve the sealing effect of the vacuum box 8. The top of the vacuum box 8 is fastened with a box cover to facilitate timely opening of the vacuum box 8 to observe the cable production status.

[0035] The working principle of the above embodiment is:

[0036] By sliding the joint tube 10 to a suitable position height relative to the bending plate 9, the bending rod 13 separated from the threaded rod 12 and the bending part of the bending plate 9 are snapped and slid in correspondence, and then the vacuum box 8 is moved close to the extrusion end of the extruder 1, and the bending rod 13 and the threaded rod 12 are aligned. At the same time, a tool is used to rotate the nut 14 on one end of the threaded rod 12, thereby pulling the threaded rod 12 to rotate. The threaded rod 12 rotates so that the bending plate 9 and the vacuum box 8 gradually move closer to the extruder 1. At this time, the joint tube 10 and the ports of the die 7 that are close to each other are finely adjusted in position again, and the joint is connected to each other, so that the cable layer that is extruded and coated on the outside of the conductor can enter the vacuum box to complete the bonding process.
