It includes a processing table, with a gantry frame fixedly connected to the top outer wall of the processing table by screws. A cylinder is fixedly connected to the top outer wall of the gantry frame by screws.

The working principle is that before the device operates, the wax feeding pipe 24 is connected with an external wax injection machine through the pipe joint 23, and parameters such as the lifting stroke of the air cylinder 3, the wax injection time of the wax injection machine and the like are preset through the PLC 35. When the device is started, an operator presses a start-stop button 36, a PLC (programmable logic controller) 35 sends out an instruction to control a piston rod of a cylinder 3 to extend downwards so as to push a top die 4 to synchronously move downwards;
When the top die 4 moves downwards, the lifting rod 5 on one side drives the pull plate 6 to synchronously move downwards along the rectangular groove 29, and as the first spring 9 is connected between the pull plate 6 and the mounting plate 8 and the pull plate 6 is limited by the limiting bar 30 to transversely move, the mounting plate 8 is pulled by the first spring 9 to move downwards along the third guide rod 32 and the first guide rod 7 in the downward moving process of the pull plate 6, at the moment, the rack 11 on one side of the mounting plate 8 moves downwards along with the mounting plate 8, the half gear 12 meshed with the rack 11 starts to rotate, the half gear 12 drives the first bevel gear 14 to synchronously rotate through the gear shaft 13, the first bevel gear 14 drives the meshed second bevel gear 15 to rotate, finally, the swinging column 16 on the top of the second bevel gear 15 drives the die carrier 17 and the bottom die 18 to rotate, when the half gear 12 rotates 180 degrees, the mounting plate 8 is just abutted to the top of the bottom baffle 10, the mounting plate 8 is limited to continue to move downwards, the half gear 12 stops rotating, and the bottom die 18 is accurately transferred to the right below the top die 4, and automatic feeding is completed;

At this time, the PLC 35 controls the wax injection machine to start, the wax liquid enters the wax injection pipe 22 through the wax inlet pipe 24 and the pipe joint 23, and is uniformly injected into the cavity of the bottom die 18 through the nozzle 25 at the bottom of the top die 4, and after the wax injection time reaches a preset value, the wax injection machine stops working, and the wax liquid is shaped into a casting head wax die in the bottom die 18;
After the casting head wax pattern is formed, the PLC 35 controls the piston rod of the cylinder 3 to shrink upwards, the top pattern 4 is pulled to move upwards, the top pattern 4 is gradually separated from the bottom pattern 18, after the positioning column 21 is completely pulled out of the positioning hole of the bottom pattern 18, the first spring 9 starts to shrink, the mounting plate 8 is pulled to reset upwards, the rack 11 moves upwards along with the mounting plate 8, the half gear 12 is driven to rotate reversely by 180 degrees, and the swinging column 16 is controlled to drive the bottom pattern 18 to reset reversely. In the resetting process, the traction head 193 of the wax mould ejection assembly 19 at the bottom of the bottom mould 18 slides along the top outer wall of the semicircular oblique sliding table 20 (the height of the semicircular oblique sliding table 20 away from the side of the top mould 4 is higher), the traction head 193 gradually lifts upwards along with the movement of the bottom mould 18, the connection plate 192 is pushed to compress the second spring 191, the connection plate 192 drives the two ejector rods 194 to synchronously move upwards, and the ejector rods 194 push the ejector rods 195 to jack up the casting head wax mould in the bottom mould 18 upwards, so that the casting head wax mould is separated from the inner wall of the bottom mould 18, and automatic demoulding is realized.
