Description

Technical Field

[0001] The invention relates to the technical field of demoulding, in particular to a precision casting demoulding device. Background Art

[0002] During the production process of castings, the upper mold and the lower mold need to be combined, and molten metal is injected into the inner cavity formed by the mold. After that, the temperature of the molten metal decreases and it can be cooled according to the inner cavity of the mold to form a casting. During this process, in order to prevent the upper mold and the lower mold from being unable to be separated from the casting, a release agent needs to be sprayed on the inner wall of the inner cavity of the mold to assist in the demolding of the casting.

[0003] In the currently available demoulding technology, an ejection mechanism is usually used to eject the casting. The impact force during ejection is large, which can easily cause the casting to be dislocated and cause the casting surface to be bumped. The impact force during ejection is small, resulting in slower demoulding. On the other hand, during the demoulding process, once the ejection process occurs, the ejection mechanism is damaged, causing the casting to lose its supporting force, resulting in collision problems between the casting and the mold.

[0011] As a preferred technical solution of the present invention: the impact piston is slidably sleeved on the inner wall of the circular tube, the conduit 2 is connected to the pressurized hole through the mounting plate 1, the outer wall of the frame 2 is fixedly equipped with a drive motor, and the output end of the drive motor is fixedly equipped with a rotating wheel.

[0012] As a preferred technical solution of the present invention: the impact seat includes a mounting block, the inner wall of the mounting block is fixedly equipped with a rubber sealing rod, and the inner cavity of the rubber sealing rod is inlaid with a impact rod.

[0013] The present invention has the following beneficial effects: The precision casting demoulding device uses a sealing ring to isolate the mold and the demoulding frame, so that the inner cavity of the mold and the demoulding frame are sealed by the sealing ring, so that the rotating wheel drives the impact piston in the inner cavity of the round tube through the push rod to achieve reciprocating movement, so that the air in the inner cavity of the round tube is transmitted to the inner cavity of the casting groove through the second one-way valve and the second conduit, the first mounting plate and the pressurizing hole, and then the casting body is exerted with an upward force through the air, thereby assisting the separation of the casting body and the casting groove; On the other hand, during the separation process of the casting body and the casting tank, there is a problem of impurities being separated from the casting body or the casting tank. By discharging air into the casting tank, the impurities can be blown out into the casting tank, thereby increasing the cleanliness of the casting tank and reducing the problem of surface scratches on the casting body. At the same time, the impact piston is used to impact the end of the rubber sealing rod, so that the rubber sealing rod drives the impact rod to impact the surface of the mounting plate 1, so that the demoulding frame drives the mold to shake at a high frequency, so that the bonding between the casting body and the casting groove is separated by high-frequency shaking; The magnet is adsorbed on the outer wall of the casting body by magnetic force, so that the rubber ball located in the inner cavity of the placement bin can be transmitted to the gap between the casting body and the casting groove through the conduit 1 and enter the inside of the casting groove, and is deposited at the bottom of the casting groove through the rubber ball, so that the mold is lifted by the rubber ball in a state of continuous shaking. In this process, the bottom of the casting groove is filled with rubber balls, so that the casting body can be continuously supported by the rubber balls, thereby solving the problem that the ejection mechanism is damaged in the traditional ejection process, causing the casting to lose its supporting force and causing collision between the casting and the mold; On the other hand, a rubber ball is used to enter the inside of the casting groove through the gap between the casting body and the casting groove, so that the casting body and the casting groove are buffered by the rubber ball, thereby avoiding the problem that the rubber sealing rod drives the impact rod to hit the surface of the mounting plate 1, causing direct collision between the casting body and the casting groove and causing damage; After the casting body is obviously lifted to a certain height by the rubber ball, that is, when there is no obvious bonding relationship between the casting body and the casting tank, the casting body can be directly taken out using traditional lifting equipment.
