DETAILED DESCRIPTION
[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0013] like Figure 1-3 As shown, a push block upward inclined top core pulling device includes a mold bracket 1, a mold embedding groove 2, support legs 3, an inclined top core pulling device 4, and a cylinder pushing device 5. The mold bracket 1 has a mold embedding groove 2 on its surface, and two groups of support legs 3 fixed with bolts are installed at the bottom end of the mold bracket 1. The inner side of the mold embedding groove 2 is installed with an inclined top core pulling device 4 connected by plugging, and the rear end bottom of the inclined top core pulling device 4 is installed with a cylinder pushing device 5 connected by magnetic attraction.
[0014] The inclined top core pulling device 4 includes an inclined top 6, a push block 7, an inclined top insert 8, a counterweight splint 9, an inclined top fixing block 10, a bolt 11, an inclined top fixing seat 12, a fixing block guide groove 13, and a bolt guide inclined groove 14. The push block 7 is installed on the inner side of the mold embedding groove 2 and the rear side of the top of the inclined top 6. The inclined top 6 and the push block 7 are installed above the inclined top insert 8 on the inner side of the mold embedding groove 2. The counterweight splint 9 fixed with screws is nested on the surface of the inclined top 6. The inclined top fixing block 10 is installed on the bottom of the inclined top 6. It is fixed by bolts 11, and the inclined top fixing block 10 is nested inside the inclined top fixing seat 12 and can slide horizontally inside the fixing block guide groove 13. The inclined top fixing block 10 and the fixing block guide groove 13 are in friction contact with each other in the left and right horizontal directions while leaving a gap in height to achieve the inclined top rising. A bolt guide inclined groove 14 is opened in the middle of the bottom end of the inclined top fixing seat 12, and the bolt 11 at the bottom end of the inclined top fixing block 10 is plugged into the bolt guide inclined groove 14 and can slide horizontally.
[0015] The cylinder pushing device 5 includes a cylinder mounting frame 15, a cylinder mounting groove 16, a cylinder 17, a push rod connecting plate 18, a magnetic block 19, a solenoid valve 20, a diverter 21, and a micro air compressor 22. The cylinder mounting frame 15 is provided with cylinder mounting grooves 16 on all sides. The cylinder 17 fixed with screws is installed on the inner side of the cylinder mounting groove 16. The middle part of the right end of the cylinder 17 is provided with a push rod connecting plate 18 fixed with screws. The middle part of the right end of the push rod connecting plate 18 is provided with a magnetic block 19 fixed by bonding. The magnetic block 19 is magnetically connected to the inclined top 6 made of metal. The left end of the cylinder 17 is provided with a solenoid valve 20 connected by a hose. The solenoid valve 20 is connected to the diverter 21 above the cylinder mounting frame 15 through a hose. The diverter 21 is connected to the micro air compressor 22 at the bottom of the right end through a hose.
[0016] The working principle of the present invention is: first, start the air compressor to provide a power source for the movement of the cylinder, and then the high-pressure air discharged from the air compressor enters the diverter and flows to different solenoid valves, and then the extension and reset of the cylinder piston rod are controlled by controlling the solenoid valve, and then the push rod connecting plate and the magnetic block are driven by the cylinder piston rod to contact the inclined top, and then the inclined top is driven by the cylinder piston rod to make horizontal movements in the front and back directions. At the same time, the bolts at the bottom of the inclined top fixing block also move horizontally on the inside of the bolt guide inclined groove and because the bolt guide inclined groove is an inclined angle, the inclined top fixing block can drive the inclined top to synchronously perform vertical lifting movements while moving horizontally, and then the inclined top moves horizontally while driving the push block to be pushed upward together, and then the two movements perform a compound movement at the same time to make the inclined top finally move along the product tripping direction, thereby realizing the upward movement of the push block and the inclined top core pulling.
[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
