DETAILED DESCRIPTION

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figures 1-5 The technical solution shown is a casting machine equipped with an automatic demolding mechanism. To solve the problem of inconvenient demolding, it discloses: a frame 1 and a base 2 set at the lower end of the frame 1. A movable upper mold 3 is installed at the upper end of the frame 1 via a hydraulic rod, and the upper end of the movable upper mold 3 is connected to a casting device 4. A fixed lower mold 5 is installed inside the frame 1, and an automatic demolding mechanism is set on the outer side of the fixed lower mold 5. The automatic demolding mechanism is equipped with a toothed plate 10, and the upper end of the toothed plate 10 is fixedly installed at the lower end of the movable upper mold 3. A toothed rod 11 is correspondingly meshed at the lower end of the toothed plate 10, and the front and rear ends of the toothed rod 11 are rotatably installed at the upper end of the frame 1. A release plate 6 is provided inside the product groove at the upper end of the fixed mold 5, and the lower end of the release plate 6 passes through the fixed mold 5. A lifting plate 7 is fixedly installed at the lower end of the release plate 6, and the left and right ends of the lifting plate 7 pass through the fixed mold 5. A return spring 8 is provided between the lower end of the lifting plate 7 and the inner wall of the fixed mold 5. A damper 9 is installed on the left and right sides of the fixed mold 5, and the lower ends of the dampers 9 are fixedly installed on the left and right sides of the lifting plate 7. A traction rope 12 is wound around the surface of the gear 11, and the middle end of the traction rope 12 is attached to the surface of the guide wheel. The traction rope 12 passes through the frame 1 and the fixed mold 5 and is fixedly connected to the lower end of the lifting plate 7.

[0034] When using this casting machine, after the support is installed in a specific position via the base 2, the hydraulic rod on the support drives the movable upper mold 3 to move, causing the movable upper mold 3 to descend and align with the fixed lower mold 5. Then, by activating the casting device 4, material is added to the product groove between the movable upper mold 3 and the fixed lower mold 5, thereby achieving casting. Figure 5 As shown, as the upper mold 3 descends, the toothed plate 10 descends to align with the toothed rod 11. The descent of the toothed plate 10 drives the toothed rod 11 to rotate. The rotation of the toothed rod 11 pulls the traction rope 12, which wraps around its surface. The retraction of the traction rope 12, under the action of the guide wheel, pulls the lifting plate 7 and the demolding plate 6 downwards. This allows the demolding mechanism to automatically retract as the casting machine progresses. Figure 4As shown, with the completion of the pouring of the tooth plate 10 is lifted with the tooth bar 11 reverse loose traction rope 12, at this time the lifting plate 7 in the reset spring 8 elastic force and the cooperation of the damper 9, lifting plate 7 is lifted with the demoulding plate 6, so that the demoulding plate 6 in the reset spring 8 elastic force and the reset force of the damper 9, drive the product in the product slot of the fixed lower mold 5 is ejected, can automatically demoulding.

At this time, the air inhaled by the driving fan 15 from the gas guide channel 17 blows upward in the inside of the fixed lower mold 5, the wind force passes through the holes on the surface of the lifting plate 7 and enters the product slot through the communication hole 19. In this way, during demoulding, air can be blown in to assist demoulding, and the product can be taken out with a gap between the product and the product slot.
