Abstract
Description
Technical Field
[0001] This utility model relates to the field of sprue treatment technology, specifically a sprue cutting and leveling device. Background Technology
[0002] A sprue is the joint between the frame and the parts formed during the casting process in a factory. It is the inlet and outlet for the flow of hot liquid plastic. The molten plastic flows into the mold cavity through the sprue. To make a model, the parts need to be cut off from the frame. Simply cut the sprue that connects the parts to the frame to easily cut off the parts. After the sprue is cut off, there will still be sprue residue, which needs to be cleaned using a sprue cutter.
[0003] In existing sprue cutting equipment, the workpiece to be processed is placed on the bottom mold, then pressed by the positioning structure, and then the stamping blade is brought close to the bottom mold to cut off the sprue of the workpiece. The hard impact of the stamping may cause some damage to the cutting edge of the stamping blade, resulting in an uneven cut. It also requires time to replace it. Moreover, the multiple positioning steps before cutting also reduce the stamping speed and affect the processing efficiency of the equipment. Optimization and improvement are needed.

[0025] A drive adjustment component is provided at the top inner side of the support frame 1. The drive adjustment component includes a drive connecting plate 6. A buffer preload plate 11 is provided at the bottom of the drive connecting plate 6. A heating plate 12 is provided at the bottom of the buffer preload plate 11. A cutting mounting block 16 is provided at the bottom of the heating plate 12. The drive adjustment component is used for the cutting and positioning adjustment of the workpiece.
[0026] Specifically, such as Figure 1 As shown, the drive connecting plate 6 is fixedly connected to the bottom end of the gas-liquid booster cylinder 4, and the gas-liquid booster cylinder 4 controls the lifting and lowering adjustment of the drive connecting plate 6.
[0027] Specifically, such as Figure 3 As shown, the heating plate 12 is installed at the bottom of the buffer pre-pressure plate 11, and the bottom of the heating plate 12 is connected to the position adjustment plate 13. The buffer pre-pressure plate 11 is used for buffering and squeezing positioning during cutting. The temperature of the cutter 19 is controlled by the heating plate 12 to ensure that the sprue is cut more evenly and reduce burrs.
[0028] Specifically, such as Figure 4As shown, a connecting block 14 is provided at the bottom of the position adjustment plate 13, and a limiting block 15 is connected to the outside of the connecting block 14. The cutting installation block 16 is provided on the outside of the limiting block 15, and a sliding adjustment groove 17 is provided on the inside of the cutting installation block 16. The cutting installation block 16 slides on the outside of the connecting block 14 through the sliding adjustment groove 17 and is limited by the limiting block 15.
[0029] Specifically, such as Figure 4 As shown, the top of the slitting mounting block 16 is provided with an elastic connecting rod 18, and the bottom of the slitting mounting block 16 is connected with a cutter 19. During the up and down movement of the slitting mounting block 16, the elastic connecting rod 18 provides connection, buffering and protection, and the cutter 19 at the bottom cuts off the water outlet.
[0030] A buffer positioning component is provided at the bottom inner side of the support frame 1. The buffer positioning component includes a support block 5, a positioning plate 7 is provided at the top of the support block 5, and a cutting support bar 9 is provided on the inner side of the positioning plate 7. The buffer positioning component is used for buffering when the workpiece sprue is cut.
[0031] Specifically, such as Figure 2 As shown, the support block 5 is installed on the bottom inner side of the support frame 1, the top of the positioning plate 7 is connected to the buffer pad 8, and the inner side of the positioning plate 7 is provided with a positioning groove for installing and positioning the workpiece. The buffer pad 8 at the top is used to buffer and protect when it comes into contact with the top drive mechanism.
[0032] Specifically, such as Figure 2 As shown, both ends of the inner side of the positioning plate 7 are connected to elastic connecting rods 10. The cutting support bar 9 is set at the top of the elastic connecting rods 10. The vertical position of the cutting support bar 9 is aligned with the cutter 19, which provides a buffer gap when the cutter 19 cuts downwards, reducing the probability of the cutter 19 blade curling.
[0033] In this embodiment: During slitting, a buffer pre-pressure plate 11 is used for buffering and pre-positioning during cutting, and then a heating plate 12 is used to control the temperature of the cutter 19 to ensure a smoother cut of the sprue and reduce burrs. The bottom cutter 19 is equipped with buffer protection when cutting the workpiece. After the workpiece is positioned in the inner groove of the positioning plate 7, the downward pressing position of the cutter 19 is offset from the positioning position of the workpiece sprue to avoid direct collision between the positioning plate 7 and the cutter 19. Then, a buffer protection cutting support strip 9 is set at the downward pressing position of the cutter 19 to ensure the service life of the cutter 19 without affecting the cutting effect of the cutter 19.
[0034] The specific solution is as follows: When cutting off the sprue of the workpiece, the workpiece is first placed in the positioning groove inside the positioning plate 7. Then, according to the positioning position of the sprue, the position of the cutter 19 is adjusted on the inside of the position adjustment plate 13. Then, the connecting plate 6 is pressed down by the control of the air-hydraulic booster cylinder 4. At this time, the buffer pre-pressure plate 11 is used for buffer squeezing and positioning during cutting. Then, the splitting mounting block 16 is adjusted for buffer protection on the outside of the connecting block 14 to fix and squeeze the workpiece. The temperature of the cutter 19 is controlled by the heating plate 12 to facilitate the cutter 19 to effectively and flatly cut off the sprue. During the cutting process, the downward pressing position of the cutter 19 is staggered from the positioning position of the sprue of the workpiece to avoid direct collision between the positioning plate 7 and the cutter 19. Then, a buffer protection cutting support bar 9 is set at the downward pressing position of the cutter 19. The cutting support bar 9 is elastically supported by the elastic connecting rod 10. While cutting off the sprue, the protective performance of the downward pressing of the cutting support bar 9 is also ensured, reducing the wear of the equipment and improving the processing efficiency of the equipment.
