AI Technical Summary
During the demolding process, the subway gate sheet is tightly wrapped on the mold due to inconsistent cooling speed, which leads to difficulty in demolding. Traditional manual operation is low and easy to cause product damage. The uneven stress of the existing demolding tool can easily cause cracks, edge drops and angle drops, resulting in low yield.
A semi-automatic mold release tool for subway gates is designed, including screw vibration motor, ball screw, ejection block, base, concave positioning block and stop. The ball screw rod is driven to move in a linear manner through the screw vibration motor, and the ejection block is driven to eject the subway gates from the mold to ensure uniform stress.
It realizes uniform stress and efficient mold release of the subway gate plate, effectively prevents product damage, improves yield, is simple to operate and high efficiency.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of subway brake pad production, and in particular to a semi-automatic demoulding tool for a subway brake pad. Background Art
[0002] Subway brake pads are synthetic products made of resin powder, rubber, filler, skeleton and other materials through compression molding. During the demoulding process, the cooling speed inside and outside is inconsistent, so the product is tightly wrapped in the mold, which makes demoulding difficult. As a key component of the subway braking system, the demoulding efficiency and quality of subway brake pads in the production process directly affect the subsequent usability and safety. Traditional subway brake pad demoulding mostly relies on manual operation. The force uniformity of subway brake pads during demoulding is low in efficiency and easy to cause product damage. Since subway brake pads are formed by hot processing, the mold temperature is high, and the mold and parts wrapped together have a certain weight, manual demoulding has high labor intensity. The existing demoulding tooling is prone to cracking, edge loss and corner loss of subway brake pads due to uneven force, resulting in serious damage to the subway brake pads and low yield rate.

DETAILED DESCRIPTION
[0011] like Figures 1 to 4 As shown, the semi-automatic demoulding tooling of the subway brake pad includes a screw vibration motor 1, a ball screw 2, an ejector block 3, a base 4, a concave positioning block 5 and a stopper 6. The screw vibration motor 1 is connected to the ball screw 2 by a thread. The screw vibration motor 1 drives the ball screw 2 to move linearly. The movement is uniform, the position is precise and it can withstand a high load. The end of the ball screw 2 away from the screw vibration motor 1 is provided with an ejector block 3. The screw vibration motor 1 is arranged on the base 4. The concave positioning block 5 is fixedly arranged on the base 4 and is located below the ejector block 3. The stopper 6 is installed on the base 4 and forms a positioning space between the concave positioning block 5 for placing the mold and subway brake pad to be demolded.
[0012] The ball screw is connected to the ejection block 3 by means of screws 7. The ball screw is provided with an annular groove, and the ejection block 3 is provided with a threaded hole corresponding to the position of the annular groove. The screw 7 extends into the annular groove through the threaded hole to fix the ejection block 3 on the ball screw 2, thereby ensuring the synchronous movement of the ejection block 3 and the ball screw; the concave positioning block 5 is in an "L" shape, and the ball screw 2 is connected to the plate thread in the vertical direction of the concave positioning block 5 to provide support for the ball screw 2 so that the ball screw remains horizontal; the ejection block 3 is provided with a groove corresponding to the shape of the subway gate piece, and the concave positioning block 5 is provided with a groove corresponding to the shape of the mold, and the mold is accurately positioned so that the ejection block 3 is evenly stressed when ejecting the subway gate piece and is not easily damaged; the stopper 6 is mounted on the base 4 by bolts, which facilitates the adjustment of the distance between the stopper 6 and the concave positioning block 5, and can be used for demolding molds of different sizes.
[0013] When in use, the mold to be demoulded and the subway brake piece are placed between the concave positioning block 5 and the stop block 6 to ensure that the mold is accurately positioned. At this time, one end of the subway brake piece is located in the groove of the ejection block 3, and the screw vibration motor 1 is started. The ball screw 2 rotates to push the ejection block 3 to eject the subway brake piece from the mold. During this process, the ball screw 2 moves at a uniform speed, which can ensure that the subway brake piece is evenly ejected by the ejection block 3, effectively preventing damage to the subway brake piece, improving the yield rate, and being simple to operate with high efficiency.
