Description

Technical Field

[0001] The invention relates to the technical field of cable production, and in particular to a hole-shaped die with adjustable aperture for cable production. Background Art

[0002] At present, in the production of cables, most of the molds used are fixed-aperture one-piece molds or split molds, each of which has its own advantages and disadvantages. One-piece mold: has higher precision and surface quality. However, the replacement steps are complicated, and even the cables in the production line need to be cut to complete the replacement. It is often used in places with strict aperture requirements and need to be in direct contact with the cable. Split mold: easy to replace. However, it needs to be spliced ​​and assembled, and there are fluctuations at the splicing point, and the surface quality is poorer than that of the one-piece mold. It is often used in places with low precision requirements and no direct contact with the cable surface. Both one-piece molds and split molds require mold replacement and mold management.

[0003] In the current industry environment, actual production is mainly based on small batch orders, which directly leads to the need for front-line workers to frequently change molds with different apertures to produce cable products of different models and specifications to meet customer needs. However, the operation of changing molds is time-consuming and labor-intensive, which greatly reduces production efficiency and increases labor costs. At the same time, the existence of molds of multiple sizes and specifications makes mold management, warehousing and storage particularly troublesome, which invisibly increases labor costs and unnecessary non-value-added production time.

[0004] However, if the aperture adjustable mold is used, it not only gets rid of the storage problem of numerous molds, but also avoids the production time wasted due to mold replacement, greatly improves production efficiency and reduces labor costs. It can be seen that the development and improvement of the aperture adjustable mold has great practical significance.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See attached Figures 1 to 5 As shown, a hole-type mold with adjustable aperture for cable production of the present application comprises a screw-connected screw cap 1 and a base 4, wherein a first through hole 11 and a second through hole 41 which pass through the screw cap 1 and the base 4 are respectively provided in the middle positions thereof, a plurality of mold cores 3 and a mold core rotation control member 2 are installed between the screw cap 1 and the base 4, each mold core 3 is a triangular plate with a certain thickness, a third through hole 21 which passes through the screw cap 1 and the base 4 is provided on the mold core rotation control member 2, each mold core 3 is circumferentially arranged around the third through hole 21, each mold core 3 is spliced ​​into a first polygon at the third through hole 21 and covers the third through hole 21, one side of the mold core rotation control member 2 is connected to the screw cap 1, and the other side is slidably connected to each mold core 3 through a first sliding structure, and one side of each mold core 3 which is away from the mold core rotation control member 2 is slidably connected to the base 4 through a second sliding structure, when the mold core rotation control member 2 rotates, each mold core 3 is driven to move away from the third through hole 21 through the first sliding structure and the second sliding structure, and when each mold core 3 moves to a different position, the aperture of the third through hole 21 changes.

[0033] The above structure is further explained below:

[0034] See attached Figures 1 to 5As shown, the screw cap 1 is in the shape of a bottle cap, and a first through hole 11 is provided in the middle of the top cover of the screw cap 1, and an internal thread 12 is provided on the screw wall of the screw cap ring of the screw cap 1. A plurality of screw cap synapses 13 are provided on the side of the top cover of the screw cap 1 facing the base 4, and each screw cap synapse 13 is arranged in sequence around the first through hole 11. The mold core rotation control member 2 includes a rotating sleeve 22 and a rotating disc 23, and a third through hole 21 is provided in the middle of the rotating disc 23. One end of the rotating sleeve 22 is fixed at the third through hole 21 and communicates with the third through hole 21, and the other end passes through the first through hole 11 and then extends out from the screw cap 1, and the rotating disc 23 is driven to rotate by rotating the rotating sleeve 22. In addition, the plurality of screw cap synapses 13 provided on the side of the top cover of the screw cap 1 facing the base 4 can reduce the contact friction between the screw cap 1 and the rotating disc 23, so that the rotating disc 23 rotates more smoothly. As an practicable manner, a bearing that matches the rotating disc 23 may be provided on the side of the top cover of the rotary cover 1 facing the base 4 to further reduce friction.

[0035] The mold core 3 is a triangular plate with a certain thickness. This embodiment uses six isosceles triangular plates, each of which has the same shape, size and thickness. The six isosceles triangular plates can be spliced ​​and combined into a hexagonal plate, that is, six mold cores 3 are combined into a hexagonal mold core, and the hexagonal mold core can completely cover the third through hole 21. As an implementable method, the shape of the mold core 3 is not limited to a triangle. According to the different aperture sizes of the third through hole 21, mold cores 3 of different shapes and numbers can be selected to combine into different polygons. In this embodiment, one side of the mold core 3 constituting the hexagon is slidably matched with the rotating disk 23 through the first sliding structure, and the other side is slidably matched with the base 4 through the second sliding structure.

[0036] The first sliding structure includes a plurality of first slider synapses 5 and a plurality of first slide rails 6, one of which is disposed on the rotating disk 23 and the other on the mold core 3, and the first slider synapses 5 slide on the first slide rails 6 to achieve sliding fit between the rotating disk 23 and the mold core 3. The second sliding structure includes a plurality of second slider synapses 7 and a plurality of second slide rails 8, one of which is disposed on the mold core 3 and the other on the base 4, and the second slider synapses 7 slide on the second slide rails 8 to achieve sliding fit between the mold core 3 and the base 4. In this embodiment, each first slider synapse 5 is disposed on one side of each mold core 3, and each first slide rail 6 is sequentially disposed on the rotating disk 23 along the circumference of the third through hole 21, one end of each first slide rail 6 faces the third through hole 23, and the other end faces the outer edge of the rotating disk 23, and each first slide rail 6 corresponds to each first slider synapse 5 one by one. Since the first slider synapse 5 is connected to the first slide rail 6, when the rotating sleeve 22 is rotated, the first slide rail 6 on the rotating disk 23 is driven to rotate, so that each mold core 3 rotates with the rotation of the first slide rail 6. Each second slide rail 8 is respectively arranged on the side of each mold core 3 away from the rotating disk 23, and each second slide rail 8 and each mold core 3 form the same direction of each side of the first polygon, so that each second slide rail 8 forms a second polygon, and the second slider synapse 7 is arranged on the base 4, and each second slide rail 8 corresponds to the second slider synapse 7 one by one, and each second slide rail 8 can fix the moving track of each second slider synapse 7. Figure 5 It can be seen that the second slider synapse 7 matched with the second slide rail 8 on one of the mold cores 3 includes five synapses, which are arranged in sequence, and there is a certain distance between one synapse and the other four synapses. A base stopper 42 is provided at the synapse far away from the four synapses, and the base stopper 42 can limit the sliding position of the corresponding synapse to prevent the second slider synapse 7 from detaching from the second slide rail 8.

[0037] During installation, the present application first places the six mold cores 3 on the second slider synapse 7 on the base 4, so that the second slider synapse 7 enters the second slide rail 8, and the second slide rail 8 is within the limit at both ends, and then the first slider synapse 5 is installed in the first slide rail 6, and finally the screw cover 1 is covered and tightened. By rotating the rotating sleeve 22, as the rotating sleeve 22 rotates, the first slide rail 6 on the rotating disc 23 pushes the first slider synapse 5, and because the second slide rail 8 and the second slider synapse 7 on the base 4 generate a collinear constraint, the six mold cores 3 are reciprocated along the collinear direction, thereby realizing the adjustment of the aperture size of the third through hole 21 by the hexagon composed of the six mold cores 3. The present application realizes the scaling of the inner hole of the mold by rotating the rotating sleeve 22 to control the mold core 3 to move back and forth along the first track 6, reducing the production time wasted due to the replacement of molds with different apertures, avoiding the labor cost and space cost caused by the storage and warehousing of a large number of molds, and greatly reducing the possibility of mold loss.

[0038] For better, see the attached Figure 1 and attached Figure 2 As shown, in this embodiment, an external thread 43 is installed on the outer wall of the base 4, and the external thread 43 on the base 4 cooperates with the internal thread 12 on the screw cap 1 to achieve a threaded connection. As an practicable manner, the connection between the screw cap 1 and the base 4 can also be bolted, doweled, etc.

[0039] For better, see the attached Figure 2 and attached Figure 4 As shown, a base sleeve 44 is installed on the side of the base 4 away from the rotating disc 23 in this embodiment. The base sleeve 44 can be used in conjunction with a production device to fix the mold on the production device.

[0040] As an implementable method, scales may be added to the surface of the rotating sleeve 22 and a scale calibration method may be provided to achieve precise control.

[0041] As a feasible method, the transmission methods such as cylinders, hydraulic cylinders or linear motors are used to realize PLC control and finally realize automatic adjustment.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
