Detailed Description

Known from the background art, the adoption of manual hanging and demoulding has potential safety hazards and low demoulding efficiency.

The analysis is carried out by combining a manual hanging and demoulding mode: when demoulding operation is carried out, the high-purity graphite mould is bound and lifted by a travelling crane, and then is turned over manually and shaken, so that the high-purity metal cast ingot naturally slides down under the action of self gravity.

The manual hanging and demoulding process has potential safety hazards and is low in demoulding efficiency. The reason for this analysis is: the weight of the high-purity metal cast ingot is 50 kg-500 kg, on one hand, operators are easily injured by crashing in the sliding process of the high-purity metal cast ingot; on the other hand, manually turning the high-purity graphite mold needs a plurality of operators to complete matching, and the time consumption is long. In addition, in case the slippage of the rope binding the high-purity graphite mold leads to the high-purity graphite mold to drop, the operator is easily injured by crashing, and the high-purity graphite mold is easily damaged, so that the production cost is improved.

To this end, the present invention provides a stripper comprising: a housing enclosing a cavity adapted to receive a mold, the housing having an opening in a top surface; the rotating shafts are fixedly arranged on two sides of the shell; the turnover supports are positioned at two sides of the shell and used for supporting the rotating shaft to suspend the shell; the motor comprises a motor shaft, and the motor shaft rotates to drive the rotating shaft to rotate so that the shell can turn over relative to the turning support.

In this embodiment, the switch 630 is disposed on the control device 600. When the shell 110 is turned to a certain angle relative to the turning support 140, the switch 630 controls the motor 200 to be turned off, so that the shell 110 stops turning, the relative positions of the shell 110 and the turning support 140 are fixed, the falling position of the metal ingot after sliding out of the mold is determined, and a protective pad can be placed at the preset falling position of the metal ingot to prevent the metal ingot from being collided.

The side wall of the housing 110 has a viewing port 180, and the viewing port 180 is communicated with the cavity 120 and the outside of the housing 110.

In one aspect, the viewing port 180 can be used to view whether the mold is properly positioned during placement of the mold into the cavity 120 by the crane; on the other hand, in the process of using the fixing member 300 to abut the mold against the inner wall of the cavity 120, it can be observed whether the mold is tightly attached to the inner wall of the cavity 120.

The stripper 100 further comprises: the base 700, the turning bracket 140 and the control device 600 are placed on the base 700.

In summary, the motor shaft rotates to drive the rotating shaft 130 to rotate, so that the housing 110 is turned over relative to the turning bracket 140, and thus the mold in the cavity 120 is turned over, and at a certain turning position, the metal ingot in the mold slides out of the mold according to the self-gravity effect, thereby completing the demolding operation. On one hand, the stripper 100 replaces manual demoulding operation, so that an operator does not need to contact with a mould and a metal cast ingot, and the safety of demoulding operation is improved. On the other hand, the stripper 100 can reduce the number of operators required for the stripping work, and the stripping work takes a short time, thereby improving the stripping efficiency.
