[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] like Figures 1-4 As shown, the utility model provides a workpiece casting demolding mechanism, including: a base 4, the top of the base 4 is fixedly connected to a mounting bin 3, the top of the mounting bin 3 is fixedly connected to a lower mold 1, the inner bottom of the lower mold 1 is movably penetrated by multiple sliding rods 5, the tops of multiple sliding rods 5 are fixedly connected to push plates 2, the inner surfaces of multiple sliding rods 5 are rotatably connected to rollers 6, the inner surface of the mounting bin 3 is symmetrically fixedly connected to a guide rod 8, the outer surfaces of the two guide rods 8 are slidably connected to a step plate 7, the inner surface of one side of the mounting bin 3 is fixedly connected to a motor 11, the output end of the motor 11 is fixedly connected to a screw rod 12, the outer surface of the screw rod 12 is threadedly connected to an adjusting plate 9, the outer surfaces of both sides of the adjusting plate 9 are respectively fixedly connected to the outer surfaces of the two step plates 7, the positions of the two step plates 7 are respectively matched with the positions of the two rollers 6, the rear end face of the screw rod 12 is rotatably connected to the inner wall of the other side of the mounting bin 3, and the outer surface of the push plate 2 is fitted to the inner surface of the lower mold 1.

[0024] When the tool is demoulded, the motor 11 is started in the reverse direction, so that the adjusting plate 9 and the step plate 7 are moved forward and reset, so that the roller 6 will roll along the inclined surface of the step plate 7, driving the sliding rod 5 and the push plate 2 to reset, which is convenient for subsequent casting work.

[0025] Example 2

[0026] like Figures 1-4As shown, a connecting frame 10 is fixedly connected between the outer surfaces of multiple sliding rods 5 near the bottom, a support rod 13 is movably passed through the bottom center position of the connecting frame 10, the top of the support rod 13 is fixedly connected to the bottom of the lower mold 1, and the bottom of the support rod 13 is fixedly connected to a fixed block 15. A spring 14 is sleeved on the outer surface of the support rod 13, one end of the spring 14 is fixedly connected to the bottom of the connecting frame 10, and the other end of the spring 14 is fixedly connected to the top of the fixed block 15.

[0027] The effect achieved by the entire embodiment 2 is: when demolding is performed by the push plate 2, the sliding rod 5 will move upward, thereby driving the connecting frame 10 to move upward along the support rod 13 and stretching the spring 14. Therefore, after the demolding is completed, the motor 11 drives the step plate 7 to reset, and the restoring force of the spring 14 when it rebounds will drive the connecting frame 10 to move downward, so that the sliding rod 5 and the push plate 2 are quickly reset.

[0028] Working principle: The mounting chamber 3 not only plays the role of structural support, but also protects the internal working parts. The upper mold and the lower mold 1 of the base 4 are used together to cast the workpiece. When the casting is completed and the mold needs to be demoulded, the motor 11 is started to drive the screw 12 to rotate, so that the adjustment plate 9 moves horizontally along the two guide rods 8, thereby synchronously driving the two step plates 7 to move to the rear side. When the step plate 7 is in motion, the guide rod 8 ensures the linearity and stability of the step plate 7 during the movement, so the roller 6 will roll along the inclined surface of the step plate 7, so that the sliding rod 5 is on the step plate 7. During the movement, it moves upward, and drives the connecting frame 10 to move upward along the support rod 13, and stretches the spring 14, driving the push plate 2 to move upward along the inner wall of the lower mold 1, and ejecting the tool formed inside the lower mold 1. The demolding efficiency is high and the operation is convenient. When the tool is demolded, the motor 11 is started in reverse, so that the adjustment plate 9 and the step plate 7 move forward and reset, so that the roller 6 will roll downward along the inclined surface of the step plate 7, and the restoring force when the spring 14 rebounds will drive the connecting frame 10 to move downward, so that the sliding rod 5 and the push plate 2 are quickly reset, which is convenient for subsequent casting work.

[0029] The wiring diagram of the motor 11 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 11 are not explained in detail.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
