Two product positioning grooves 24 and a sprue discharge hole 25 located between the two product positioning grooves 24 are provided inside the product positioning mold 22. The product positioning mold 22 is embedded in the top of the jig body 21 and is locked by screws, which facilitates the later replacement of product positioning molds 22 of different specifications.

[0027] A cutting upper die 3 is provided at the output end of the cylinder 15, and the cutting upper die 3 includes a cutter head mounting plate 31. At least two cutting heads 32 are provided at the bottom of the cutter head mounting plate 31. The two cutting heads 32 correspond to the two product positioning grooves 24 respectively. When in use, the formed product is placed inside the product positioning groove 24 so that the product water outlet is located at the water outlet discharge hole 25. The cylinder 15 is started to drive the cutter head mounting plate 31 to descend. The cutter head mounting plate 31 drives the two cutting heads 32 to descend at the same time to cut the two ends of the product water outlet. After the cutting is completed, the detached product water outlet falls into the inside of the receiving box 41.

[0028] As a specific technical solution of this embodiment, at least two slide bars 23 are arranged on the top of the jig body 21, and the two slide bars 23 are symmetrically arranged. The output end of the cylinder 15 extends to the bottom of the top plate 12 and is provided with a driving plate 16. The top of the slide bar 23 is movably penetrated into the interior of the driving plate 16, and the cutter head mounting plate 31 is installed at the bottom of the driving plate 16. The top of the cutter head mounting plate 31 is embedded in the bottom of the driving plate 16 and is locked by screws, which facilitates the later replacement of cutting upper dies 3 of different specifications. The cylinder 15 is started to drive the driving plate 16 to descend, and the driving plate 16 is still on the slide bar 23. The setting of the two slide bars 23 ensures the stability of the lifting and lowering movement of the driving plate 16.

[0029] As a specific technical solution of this embodiment, the bottom of the cutter head mounting plate 31 is connected to a pressure plate 34 through a plurality of springs, and the bottom end of the cutting head 32 passes through the bottom of the pressure plate 34. A limiting rod 33 is provided at the bottom of the cutter head mounting plate 31 which is sleeved with the spring and the pressure plate 34. When the driving plate 16 drives the cutter head mounting plate 31 to descend, the pressure plate 34 first contacts the molded product and presses it, thereby avoiding shaking of the molded product when cutting the water outlet, ensuring the stability during the water outlet cutting operation, and making the water outlet smoother and free of burrs.

[0030] As a specific technical solution of this embodiment, a plurality of stabilizing rods 17 are movably provided inside the top plate 12, and the bottom end of the stabilizing rod 17 is fixedly connected to the top of the driving plate 16. When the driving plate 16 moves, the stabilizing rod 17 is driven synchronously, and the stabilizing rod 17 cooperates with the sliding rod 23 to further ensure the stability of the driving plate 16 and the cutting head 32 during the movement.

[0031] As a specific technical solution of this embodiment, a fixing block 18 for fixing the jig body 21 is provided on the top of the base 11, and the number of the fixing block 18 is not less than one. A movable hole 19 is opened inside the fixing plate 14, and a circle of rubber pads is sleeved inside the movable hole 19. The movable hole 19 is sleeved with the connecting rod 46 through the rubber pad, which effectively increases the resistance of the connecting rod 46 when sliding, and ensures the stability of the connecting rod 46 and the material receiving box 41.

[0032] As a specific technical solution of this embodiment, a fixed rod 13 opposite to the fixed plate 14 is also provided between the base 11 and the top plate 12, and two starting switches 111 and a temperature display 112, a time relay 113 and a stop switch 114 located between the two starting switches 111 are also provided on one side of the base 11. A heater and a temperature sensor are provided inside the cutting head 32. The temperature display 112 is electrically connected to the temperature sensor and the heater for displaying the heater temperature and the temperature detected by the temperature sensor. The time relay 113 is used to control the cylinder 15. The design of the two starting switches 111 avoids the situation where the hands of personnel are located between the positioning jig 2 and the cutting upper mold 3 during operation, which makes it safer to use.

[0033] As a specific technical solution of this embodiment, it also includes a material receiving component 4, which includes a material receiving box 41 movably arranged inside the fixture body 21, the water outlet discharge hole 25 is located just above the material receiving box 41, and mounting grooves 42 are provided on both sides of the material receiving box 41, and a dust suction fan 43 is arranged inside the mounting groove 42, and the dust suction fan 43 is arranged obliquely, and a filter screen 44 is arranged on one side of the dust suction fan 43, and a connecting seat 45 is provided on one side of the inner wall of the material receiving box 41, and a connecting rod 46 is movably arranged inside the connecting seat 45, and one end of the connecting rod 46 away from the connecting seat 45 is movably penetrated into the movable hole 19, and one end of the connecting rod 46 located inside the connecting seat 45 is connected to a spring buckle 48 through a spring, and the top of the spring buckle 48 The part passes through the top of the connecting seat 45, and a handle 47 is provided on one side of the material receiving box 41. The material receiving box 41 is pulled by the handle 47 to move to the inside of the fixture body 21, so that the material receiving box 41 is opposite to the sprue discharge hole 25. After the cutting head 32 cuts off the sprue of the molded product, the product sprue directly falls into the inside of the material receiving box 41 through the sprue discharge hole 25. During operation, the dust suction fan 43 is started, and the dust suction fan 43 continuously sucks the sprue discharge hole 25, which can adsorb the debris and dust generated during the sprue cutting operation on the filter screen 44, reducing the impact on the working environment, making the working environment free from dust interference, and making it more hygienic and safe to use. When the material receiving box 41 needs to be cleaned, the spring buckle 48 is pressed to retract into the inside of the connecting rod 46, and the connecting seat 45 and the connecting rod 46 can be separated through the material receiving box 41.

[0034] To sum up, this safe and efficient water nozzle cutting device, the starting cylinder 15 can drive the two cutting heads 32 to cut the two ends of the product water nozzle at the same time, which greatly improves the water nozzle cutting efficiency. The cooperation between the slide bar 23 and the stabilizing bar 17 ensures the stability of the movement process of the cutting head 32. The pressure plate 34 cooperates with the spring to ensure the stability of the molded product when cutting the water nozzle, making the water nozzle after cutting smoother and free of burrs. The water nozzle after cutting can be collected through the collecting box 41, making the working environment more tidy and meeting the user's use needs.
