The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figure 1-4 As shown, the present application relates to a semi-automatic water-cutting device, which comprises: a frame 1, a mounting seat and a light curtain fixedly mounted on the inner wall of the frame 1, a punching module 2 for cutting the water-cutting of injection-molded products, and a positioning module 3 for positioning the water-cutting of injection-molded products;

[0032] By setting the punching module 2, the device can automatically punch the sprue of the injection molded product by mechanical means, without the need for manual cutting to complete the separation of the injection molded product and the sprue, thereby improving the cutting efficiency, reducing the labor cost, and solving the problem of uneven incision after shearing, which affects the product quality due to the influence of manual shearing technology. The injection molded product to be processed can be positioned by the positioning module 3. On the one hand, it can ensure that the injection molded product is located at the correct position. In the sprue punching process, it helps to improve the accuracy and consistency of sprue punching. On the other hand, it helps to improve the stability and efficiency of punching. By ensuring the stable position of the injection molded product, the deviation and error in the punching process can be reduced, thereby improving the production efficiency and product quality. Through the cooperation between the punching module 2 and the positioning module 3, the device can be convenient for positioning the injection molded product, ensuring the accuracy of punching the sprue, improving the quality of the injection molded product, and at the same time realizing the automatic punching of the sprue of the injection molded product by mechanical means, solving the problem of uneven incision after shearing, which is affected by manual shearing technology, and further improving the quality of the injection molded product.

[0033] By setting up the light curtain, it is possible to detect whether there are foreign objects or human bodies entering a specific area, thereby automatically stopping the operation of the device and avoiding possible dangerous situations, thereby protecting the safety of operators during the process of punching and cutting the water outlet.

[0034] The punching die set 2 includes: an upper die base 24 arranged in the inner cavity of the frame 1, a punching head 27 fixedly installed at the bottom center of the upper die base 24 and used to cut off the water outlet of the injection molded product, a guide column 25 and a limit column 26 fixedly installed at the bottom of the upper die base 24, a driving member 21 that drives the upper die base 24 to move up and down, and a limit assembly that limits the upper die base 24 when it moves up and down; a fixed plate is installed on the inner wall of the frame 1, and the driving member 21 is installed on the side wall of the fixed plate.

[0035] When the water outlet of the injection molded product is to be punched, the upper mold base 24 can be driven to move downward by starting the driving member 21, and the upper mold base 24 drives the punching head 27 to move downward. By moving the punching head 27 downward, the water outlet of the injection molded product to be processed can be cut off, so that the device can automatically punch the water outlet of the injection molded product by mechanical means, and there is no need for manual shearing to complete the separation of the injection molded product and the water outlet, thereby improving the shearing efficiency and reducing the labor cost, and solving the problem of uneven incision after shearing due to the influence of manual shearing technology, which affects the product quality. In this process, through the setting of the guide column 25 and the limit column 26, the moving direction of the punching head 27 can be positioned during the punching process, and the distance between the punching head 27 and the positioning module 3 is guaranteed, thereby effectively preventing the punching head 27 from descending too far and crushing the injection molded workpiece. After the water outlet is cut off, the driving member 21 drives the upper mold base 24 to reset upward, wherein the driving member 21 is preferably a cylinder.

[0036] The limit assembly includes: a guide sleeve 23 inserted on the upper die seat 24, a guide column 22 installed through the inner cavity of the guide sleeve 23, one end of the guide column 22 is fixedly installed at the bottom of the fixing plate, and the other end is fixedly installed at the top of the mounting seat.

[0037] During the punching process of the injection molded workpiece, the cooperation between the guide sleeve 23 and the upper die seat 24 can limit the upper die seat 24, thereby preventing the upper die seat 24 from deflecting during movement and ensuring the cutting accuracy of the water outlet.

[0038] Four sets of guide pins 22 and guide sleeves 23 are provided and distributed at the four corners of the upper die base 24 .

[0039] Since the guide pillar 22 and the guide sleeve 23 are located at the four corners of the upper die base 24, they can simultaneously play the same limiting role on the four corners of the upper die base 24, so that the upper die base 24 has higher stability during movement and ensures the cutting accuracy of the nozzle.

[0040] The positioning module 3 comprises: a lower mold base 31 fixedly mounted on the top of the mounting base, and a positioning fixture 32 fixedly mounted at the top center of the lower mold base 31 .

[0041] When the sprue of the injection molded product to be processed is cut, the injection molded product to be processed is manually placed on 31 and sleeved on the outer edge of the positioning fixture 32. Due to the setting of the positioning fixture 32, the injection molded product can be positioned. On the one hand, it can ensure that the injection molded product is located in the correct position. In the sprue punching process, it helps to improve the accuracy and consistency of the sprue punching. On the other hand, it helps to improve the stability and efficiency of the punching. By ensuring the stable position of the injection molded product, the deviation and error in the punching process can be reduced, thereby improving production efficiency and product quality. After the punching is completed, the product is taken out manually and the material head falls off.

[0042] A safety shield 4 is installed on the side wall of the frame 1, and the safety shield 4 is arranged in a concave shape around the outside of the frame 1. Through the setting of the safety shield 4, the manual feeding position and the material taking position are completely isolated from the material taking position by the safety shield 4, protecting the safety of the operator.

[0043] A control member 5 is installed on the upper side wall of the frame 1. The control member 5 is electrically connected to the driving member 21. The control member 5 includes: two start switches and an emergency stop switch. The two start switches are respectively located on both sides of the emergency stop switch. When punching the injection molded product to be processed, both hands press the two start switches at the same time. At this time, the device cuts off the water outlet of the injection molded product to be processed. Since the staff needs to press the two start switches at the same time with both hands, the staff can prevent their arms from reaching into the device during punching, thereby ensuring the safety of the operator. By pressing the emergency stop switch, the device can be stopped urgently, thereby facilitating the handling of emergency problems that occur during the operation of the device.

[0044] A support plate is fixedly installed at the bottom of the inner cavity of the frame 1, and a power box is installed on the top of the support plate. The power box is electrically connected to the control component 5 and the driving component 21. The power box can provide power to the control component 5 and the driving component 21.

[0045] A moving part is installed at the bottom of the frame 1. In the present application, the moving part includes four moving wheels and four fixed seats. The device can be easily moved through the four moving wheels, which improves the convenience of use. After moving to the required position, the device can be supported and fixed through the four fixed seats to prevent sliding during use, thereby improving the stability of use.

[0046] Working principle: When in use, first manually position the injection molded product to be processed on the lower mold base 31 through the positioning fixture 32, connect the power supply, and then press the start switch with both hands at the same time, and drive the punching head 27 to move downward through the driving part 21 to punch the water outlet. After the water outlet is cut, the punching head 27 is driven by the driving part 21 to reset upward, and the product is manually removed to complete the water outlet removal.

[0047] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
