Description

Mold separation device {SEPARATING APPARATUS OF MOLD}

The present invention relates to a mold separating device, and more particularly, to a mold separating device for automatically and easily separating molds stuck to each other after an aluminum extrusion operation.

In general, two molds are used in the aluminum extrusion operation, and after use, the aluminum extrudates remaining in the mold are hardened and the molds are stuck to each other. Therefore, in order to reuse the mold, the molds must be separated from each other and the aluminum extrudate inserted in the separated mold must be removed.

To this end, the mold must first be removed, but to date, a wedge such as a chisel has been inserted into the gap between the mold, and it is proceeding by hand with a hammer (hammer). This caused a problem of reduced work efficiency along with a lot of work time and labor consumption.

In order to solve this, a device for separating the mold using a mold frame and then separating it using a lifting wedge was developed, but this also still requires a blow with a hammer to separate the workforce, thus raising the problem of labor and raising work efficiency. There are many cases where it is still carried out manually as in the past.

Therefore, there is a need for a more economical, safe, and efficient mold separation device for automatically separating molds.

1 is a perspective view according to an embodiment of a mold separation device according to the present invention, and FIG. 2 is a front view of FIG. 1.

With reference to Figures 1 and 2 will be described the overall structure of the mold separation device of the present invention.

The present invention relates to a mold (1) separation device for separating the mold (1) attached to each other after the aluminum extrusion operation.

The mold 1 applied to the present invention is formed in a disk shape having a predetermined width, and a hole (not shown) corresponding to the extrusion shape is formed. After the extrusion operation, between the mold 1 and the mold 1, the extrudates harden and mutually adhere to each other. That is, in the case of the aluminum extrudate, the aluminum is hardened and the mold 1 is in a state in which it is mutually bound.

The present invention is a device for separating the molds 1 from each other by pressing the gaps of the molds 1 to which they are stuck together.

To this end, the present invention, the mold 1 separation device comprises a body 10, a lifting means 20, a pressure separator 30, a first rotating roller 40 and a second rotating roller 60.

The body 10 is a part forming the overall appearance of the mold 1 separation device, and is preferably composed mainly of a metal material. The front surface of the body 10 is open, and the rear surface of the body 10 may also be configured in an open form to secure a work space, reduce weight, and reduce material costs. A hole (not shown) is formed on the upper part of the body 10, and the lifting means 20 are coupled to the upper part of the hole, so that the lower part of the lifting means 20 is located inside the hole to be elevated inside the body 10. It has a structure. Since the upper surface of the body 10 is supported by both sides of the body 10, considering the pressing force of the pressure separator 30 separating the mold 1, the material and thickness of both sides of the body 10 are determined. It is preferred.

On the other hand, in front of the front of the body 10, a rolling plate (not shown) or a conveying roller (not shown) formed in an inclined direction may be configured to more easily perform the movement of the working or working mold 1.

The lifting means 20 includes a hydraulic cylinder 21, a hydraulic pump 22 and an oil tank 23.

The hydraulic cylinder 21 is coupled to the lower portion of the hole (not shown) formed on the upper surface of the body 10, and the lifting cylinder lower portion of the hydraulic cylinder 21 through the hole is inside the body 10. It is located and has a structure that is elevated within the body 10. The structure, shape, and functions of the hydraulic pump 22 and the oil tank 23 for driving the hydraulic cylinder 21 are well-known technologies, so detailed descriptions thereof will be omitted. However, in the present invention, when using a mold 1 having a diameter of 230 to 300 mm, it is proposed to use a hydraulic cylinder 21 of 30 ton class. On the other hand, the hydraulic cylinder 21, the hydraulic pump 22 and the oil tank 23, the structure of the transfer pipe and the on-off valve connected to each other is omitted for convenience.

The pressure separator 30 is a circular metal material having a thin thickness that is inserted into a gap formed between the outer circumferential parts of the mold 1, and is widened toward the inner center. A hole (not shown) is formed in the pressure separator 30 and is rotatably coupled to the lower portion of the lifting cylinder located inside the body 10 through the hole. That is, the central axis is rotatably coupled to the lower portion of the elevating means 20 in a vertical direction from a fixed position, and when the descent is lowered, the attachment portion between the molds 1 positioned at the lower portion is pressed vertically downward. At this time, the structure in which the pressure separator 30 is rotatably coupled rather than fixed is important. When pressing the mold (1) rotating at a low speed while being coupled to the lower portion of the lifting cylinder in a fixed form without rotating the pressure separator (30), the mold is formed by the rotational force of the mold (1) and the pressing force applied vertically downward. (1) is out of the settled position or is bounced out. Therefore, the above-described problem can be solved only by rotatably coupling the pressure separator 30.

The first rotating roller 40 rotates at a low speed by the driving means 50 and rotates the mold 1 which is in contact with the upper part. The mold 1 is not coupled to a separate rotating means and is rotated by receiving the rotational force of the first rotating roller 40 to the surface. Therefore, it is preferable to form the friction projection 41 on the surface of the first rotary roller 40 to improve the contact supporting force with the outer peripheral surface of the mold 1.

The driving means 50 is coupled to one end of the first rotary roller 40 and is located outside the side of the body 10. Of course, it may be located inside the body 10, but it is preferable to place it outside the body 10 to improve workability and prevent damage during operation. The driving means 50 may use a hydraulic motor, and can be operated by being connected to the hydraulic pump 22 when using the hydraulic motor. In addition, a reduction gear is coupled to the driving means 50 to rotate the first rotating roller 40 at a low speed. That is, during high-speed rotation, the mold 1 is disengaged or deviated from the fixed position by the vertical pressing force of the pressure separator 30 and the high-speed rotation of the first rotating roller 40. Therefore, it is preferable to rotate at a low speed, and for example, it is preferable to rotate the rotational speed of the first rotation roller 40 at a low speed so that the mold 1 rotates 2 times per minute. The rotation speed can be set differently depending on the working method.

The second rotating roller 60 is positioned horizontally spaced from the first rotating roller 40 and supports the mold 1 along with the first rotating roller 40. That is, since only the first rotating roller 40 alone cannot support the mold 1, the at least one second rotating roller 60 is configured to support the mold 1 at the same time, and the rotational force of the mold 1 It is a structure that is rotated so as not to interfere with. However, the second rotary roller 60 does not rotate in combination with a separate driving means 50, but is rotated together by the rotational force of the mold 1 rotating according to the rotation of the first rotary roller 40. It is preferable to configure the friction protrusions 61 to improve the contact supporting force with the mold 1 on the surface of the second rotating roller 60, and the friction protrusions 41 and 61 are illustrated in the form of a net in the drawing.

The present invention having the above-described structure, the mold (1) separating device is a pressure separator (30), the first rotary roller (40) and the second rotary roller (60) seated on the mold (1) pressurized separator (30) ), The first rotating roller 40 is pushed downward by the mold 1 and the rotational force is reduced to rotate at a lower speed than the original rotational speed. . Through this structure, when the mold 1 is separated, the operator can automatically rotate the mold 1 without rotating the mold 1 by hand. That is, as an example, in order to separate the mold 1, the two parts of the mold 1 must be pressed and separated with the pressure separator 30, and the mold 1 when the mold 1 is pressed once with the pressure separator 30 Assuming that one part (half) of is separated, basically, if the first rotating roller 40 does not automatically rotate, the operator has the trouble of rotating the mold 1 by hand and rotating it one by one. Accordingly, when the first part of the mold 1 is pressed through the pressure separator 30, the first rotation roller 40 is pressed while the mold 1 is pressed downward by the pressing force, thereby reducing the rotational force of the driving means 50. do. As described above, when the rotational force of the driving means 50 is reduced, the vertical lower pressing force and the rotational force by the pressure separator 30 may collide, thereby preventing the mold 1 from being out of position or the mold 1 being thrown out. . In addition, when the pressing force by the pressure separator 30 is released, the first rotating roller 40 is rotated by operating normally again to rotate the mold 1. The operator can easily separate the mold 1 by viewing the rotational state of the mold 1 and pressing the remaining second part of the mold 1. Of course, it is also possible to configure the driving means 50 to stop when the mold 1 is pressed with the pressure separator 30 to stop it, and to operate the driving means 50 again when the pressure on the mold 1 is released. Since a separate control unit has to be configured, it is preferable to configure as described above for cost reduction.

On the other hand, when the pressure separator 30 is used while being lifted while being coupled only to the lower portion of the hydraulic cylinder 21, the horizontal axis or the vertical axis may be displaced by frequent pressing operations. That is, since the pressure separator 30 must be positioned and lifted in an exactly vertical state, it is precisely positioned in a gap between the molds 1, so it is important to keep these axes from twisting.

Therefore, the lifting guide grooves 11 are formed on both inner surfaces of the body 10, the horizontal holding shaft 70 penetrates the rotational center shaft of the pressure separator 30, and both ends of the horizontal holding shaft 70 are elevated guides. Located in the groove 11 has a structure that is lifted together when the lifting means 20. In addition, it is preferable to combine the bearings 71 which smoothly move up and down, respectively, at both ends of the horizontal holding shaft 70. With the configuration of the horizontal holding shaft 70, the horizontal axis and the vertical axis of the pressure separator 30 can be prevented from being distorted, and the supporting force of the pressure separator 30 can be further improved.

One side of the body 10 may further include a lifting means 20, that is, an operation means 80 for controlling the lifting of the hydraulic cylinder 21. The operation means 80 is configured in the form of a lever that can be gripped by an operator by hand, and is configured to move to upper, middle, and lower positions. When positioned on the upper, the lifting means 20 rises, and when located on the lower, the lifting means 20 descends. Normally, it is located in the middle, and when it is in the middle, the lifting means 20 stops the lifting operation. The operator can more easily perform the separation operation of the mold 1 through the operation means 80. On the other hand, the operation means 80, although not shown, can also be implemented in the form of a scaffolding switch and can be implemented in other known forms for the convenience of the operator.

In addition, the support means 90 may be further provided on both sides of the body 10.

The support means 90 may include a support shaft 91, a rotating plate 92, a supporting plate 93 and a gripping member 94.

The support shaft 91 has a circular rod shape, and a thread is formed on the outer circumferential surface. The support shaft 91 is not shown in detail, but is coupled through holes formed on both sides of the body 10, and a thread corresponding to the thread is formed on the inner circumferential surface of the hole. The support plate 93 in the form of a disc is coupled to the end of the support shaft 91 located inside the body 10. The support plate 93 supports the mold 1, which is separated from both sides after the mold 1 is separated from the mold at a predetermined interval, so that the mold 1 does not completely collapse. Because the mold (1), which is mostly made of metal, is separated from the mold (1), the mold (1) may be damaged due to the impact of the weight of the mold (1) while the separated mold (1) collapses on both sides. It is preferable to support the mold 1 with the support plate 93 so that it does not completely collapse.

The rotating plate 92 is coupled to the end of the supporting shaft 91 located outside the body 10, and the operator rotates the rotating plate 92 forward and backward to move the supporting shaft 91 in the inner and outer directions of the body 10. Can be. The operator can adjust the interval of the support plate 93 from the mold 1 by rotating the rotating plate 92 forward and backward according to the width (thickness) of the mold 1.

By further comprising a gripping member 94, such as a handle that can be gripped by the operator's hand, on the rotating plate 92, the forward and reverse rotation of the support shaft 91 can be more easily performed.

The use state of the mold (1) separation device according to the present invention described above will be described with reference to FIGS. 3 to 5 as follows.

3 is a view showing a state in which the mold (1) is seated on the first rotating roller (40) and the second rotating roller (60), and FIG. 4 separates the mold (1) while elevating the pressure separator (30). 5 is a view showing a state in which the separated mold 1 is supported on the support plate 93.

First, the operator seats the mold 1 to be separated on the first rotating roller 40 and the second rotating roller 60. At this time, the forward and reverse rotation of the support shaft 91 through the gripping member 94 adjusts the separation distance between the mold 1 and the support plate 93.

Thereafter, the operation means 80 is lowered to lower the pressure separator 30. The descending pressure separator 30 presses the gaps between the molds 1 to separate the attached molds 1 from each other.

Again, the operation means 80 is raised to the upper portion, and the pressure separator 30 is elevated. After the pressure separator 30 is elevated, the rotation state of the mold 1 is viewed, and the operation means 80 is lowered again to lower the pressure separator 30. The descending pressure separator 30 separates the attached molds 1 from each other by pressing different gaps between the molds 1 that are not separated. This operation is repeated twice to several times to completely separate the mold 1 from each other.

After the mold 1 completely separated as shown in FIG. 5 is removed from the mold 1 separation device, and the mold 1 to be newly worked is supported on the first rotating roller 40 and the second rotating roller 60 again, The above-described operation is repeated.

According to the present invention as described above, it is possible to automatically and easily perform a mold 1, which is firmly attached to each other by an aluminum extrusion operation, etc. through the mold 1 separator device of the present invention, thereby reducing labor and working efficiency. Work safety can be improved with improvement.
