[0028] Example: Figures 1-8 As shown, a gate cutting machine includes a frame 100, a power component 200, a transmission component 300, a cutting component 400 and a jig transfer component 500. The jig transfer component 500 is installed on the frame 100. The jig transfer component 500 is used to place the product component 600, and the jig transfer component 500 can drive the product component 600 to move. A support frame 130 is installed on the frame 100, and the transmission component 300 is installed on the support frame 130.

[0029] like Figures 7-8As shown, the product assembly 600 includes a product 610 and a gate 620 fixedly connected to the product 610. In operation, the product assembly 600 is fixed in the jig transplanting assembly 500, the jig transplanting assembly 500 drives the product assembly 600 to the cutting station, the product assembly 600 is located between the upper cutting assembly 410 and the lower cutting assembly 420, the power assembly 200 drives the transmission assembly 300 to operate, the transmission assembly 300 drives the upper cutting assembly 410 and the lower cutting assembly 420 to operate towards the product assembly 600 at the same time, and cuts the gate 620 on the product assembly 600 at the same time, until the gate 620 is cut off, thereby completing the gate removal operation of the product.

[0030] As shown in Figure 2 The power assembly 200 includes a servo motor 210 and a shaft coupling, which is not shown in the figure. The servo motor 210 is connected to the transmission assembly 300 through the shaft coupling, and the servo motor 210 is installed on the support frame 130. The rotating shaft of the servo motor 210 is connected to the shaft coupling, and the shaft coupling is connected to the transmission assembly 300. The cutting assembly 400 is installed on the transmission assembly 300, so that the servo motor 210 can drive the cutting assembly 400 to operate synchronously when the servo motor 210 operates. Using the servo motor 210 as the power source of the cutting assembly 400 can improve the stability of the cutting assembly 400 during operation and ensure the quality of the product after cutting.

[0031] As shown in Figure 1 and Figure 6 The transmission assembly 300 includes a lead screw 310, an upper lead screw nut 320 and a lower lead screw nut 340. The lead screw 310 is connected to the power assembly 200, i.e. the lead screw 310 is connected to the servo motor 210 through the shaft coupling. The upper lead screw nut 320 and the lower lead screw nut 340 are both screwed to the lead screw 310. The upper lead screw nut 320 is fixedly installed with an upper sliding block 330, and the upper cutting assembly 410 is fixedly installed on the upper sliding block 330. The lower lead screw nut 340 is fixedly installed with a lower sliding block 350, and the lower cutting assembly 420 is fixedly installed on the lower sliding block 350. The lead screw 310 can drive the upper lead screw nut 320 and the lower lead screw nut 340 to operate at the same time, and the operating directions of the upper lead screw nut 320 and the lower lead screw nut 340 are opposite. The servo motor 210 drives the lead screw 310 to rotate, and the lead screw 310 drives the upper lead screw nut 320 and the lower lead screw nut 340 to operate in opposite directions at the same time, i.e. the upper cutting assembly 410 and the lower cutting assembly 420 operate in opposite directions. As shown in Figure 1 andFigure 3 As shown, the product assembly 600 to be cut is fixed in the jig transplanting assembly 500, the jig transplanting assembly 500 drives the product assembly 600 to the cutting station, at this time, the upper cutting assembly 410 is located above the product assembly 600, the lower cutting assembly 420 is located below the product assembly 600, the servo motor 210 drives the screw rod 310 to rotate, the screw rod 310 drives the upper cutting assembly 410 to run downward and the lower cutting assembly 420 to run upward, so as to cut off the gate by the upper cutting assembly 410 and the lower cutting assembly 420. After cutting, the servo motor 210 drives the screw rod 310 to rotate in the opposite direction, so that the upper cutting assembly 410 and the lower cutting assembly 420 move away from the product assembly 600.

[0032] Optionally, the outer side wall of the screw rod 310 is provided with an upper section outer thread and a lower section outer thread with opposite threads, for example, when the upper section outer thread is a positive thread, the lower section outer thread is a reverse thread; when the upper section outer thread is a reverse thread, the lower section outer thread is a positive thread. The upper screw rod nut 320 is screwed on the upper section outer thread, and the lower screw rod nut 340 is screwed on the lower section outer thread. Therefore, when the screw rod 310 rotates, the upper screw rod nut 320 and the lower screw rod nut 340 can run in opposite directions.

[0033] As shown in Figure 6 The support frame 130 is provided with a sliding rail 131, and the upper sliding block 330 and the lower sliding block 350 are slidingly installed on the sliding rail 131. In a possible implementation, the support frame 130 on both sides of the screw rod 310 is respectively provided with a sliding rail 131, so as to improve the stability of the upper sliding block 330 and the lower sliding block 350 when sliding.

[0034] As shown in Figure 2 and Figure 6As shown, the upper cutting assembly 410 includes an upper cutter fixing seat 411 and an upper cutter 412 installed on the upper cutter fixing seat 411, and the lower cutting assembly 420 includes a lower cutter fixing seat 421 and a lower cutter 422 installed on the lower cutter fixing seat 421. The upper cutter fixing seat 411 and the lower cutter fixing seat 421 are fixedly installed on the transmission assembly 300. Optionally, the upper cutter fixing seat 411 is fixedly installed on the upper sliding block 330, and the lower cutter fixing seat 421 is fixedly installed on the lower sliding block 350. Optionally, the upper cutter 412 and the lower cutter 422 are equal in structure, and the upper cutter 412 and the lower cutter 422 are provided with inclined cutting edges. If a conventional upper cutter with a cutting angle is used, and the lower cutter is a right angle structure, the upper and lower cutting edges must be staggered before the product can be cut off. This method can cause the product to have burrs on the lower cutter surface, and the longer the time, the larger the burrs. Moreover, the operator is easy to damage the upper and lower cutter edges during debugging. In the present application, the upper cutter 412 and the lower cutter 422 are provided with inclined cutting edges, and the cutting edges of the upper cutter 412 and the lower cutter 422 are arranged at a symmetrical angle with respect to the horizontal plane. Therefore, any edge position of the product can be cut off. The upper cutter 412 and the lower cutter 422 are driven to run in opposite directions by the servo motor 210. Therefore, the position of the cutter can be accurately controlled, the upper and lower cutting edge portions of the product are smooth and free of burrs, the operator is easy to debug, and the work efficiency and safety are greatly improved.

[0035] Optionally, the upper cutter 412 is screwed on the upper cutter fixing seat 411, and the lower cutter 422 is screwed on the lower cutter fixing seat 421. Therefore, the operator can rotate and adjust the cutting edge position of the upper cutter 412 and the lower cutter 422, to ensure accurate control of the cutting edge position.

[0036] As shown, Figure 2 The jig transplanting assembly 500 includes a linear motor module 510 and a product fixing jig 520 installed on the linear motor module 510. The linear motor module 510 can drive the product fixing jig 520 to run in the horizontal direction. The product fixing jig 520 is used to fix the product assembly 600. The linear motor module 510 is horizontally installed on the rack 100, so that it can drive the product fixing jig 520 to run in the horizontal direction. Figures 7-8 As shown, a set of molds has eight holes, that is, a set of molds can form eight products 610 at a time. Figure 5 As shown, the product fixing jig 520 is provided with eight installation cavities for placing the product assembly 600 coming out of a set of molds. After the injection mold takes out the product assembly 600, it can be positioned and clamped and fixed at one time. Different product fixing jigs 520 can be replaced according to different product assemblies 600, to realize the function of rapid clamping and positioning of products. The gate of different types of products can be quickly changed, to be suitable for products of various specifications, and to improve the utilization rate of the equipment.
