[0024] As shown in Figure 1 , Figure 2 A vertical parting molding machine according to the present application comprises a frame, a mold cavity assembly 3 for manufacturing a sand mold is arranged on the frame, a molding mechanism for extrusion molding of the sand mold is arranged on both sides of the mold cavity assembly 3, and a sand blasting cylinder 4 for sand blasting is arranged above the mold cavity assembly 3. The sand blasting cylinder 4 adopts an existing structure.

[0025] The frame includes a base 1 and a top plate 2. The top plate 2 is located above the base 1 and is connected to the base 1 by several support columns. The cavity assembly 3 is located on the base 1. The top plate 2 is provided with a lifting opening for the lifting of the molding mechanism and a sandblasting passage for the lifting of the sandblasting cylinder 4.

[0026] The shaping mechanism includes a central pressure plate 7, which is connected to a lifting plate 9 via a uniform pressure application structure. The central pressure plate 7 is surrounded by a pressure plate size adjustment structure, and the lifting plate 9 is connected to the frame via a lifting structure.

Gears 22 are symmetrically arranged at both ends of the outer side of the frame 20, perpendicular to gears 17. Gears 22 are housed within an adjusting seat 23, which contains a rack, and gears 22 mesh with the rack inside the adjusting seat 23. A threaded rod 24 is provided on the adjusting seat 23, and a threaded hole is provided on the adjusting seat 23. One end of the threaded rod 24 is rotatably connected to the frame 25, and the other end of the threaded rod 24 passes through the threaded hole on the adjusting seat 23 and is connected to the output shaft of the front and rear adjusting motor 26.

[0032] The vertical parting line shaping method of the present invention includes the following steps: Step 1: The central pressure plate 7 and the adjusting base plate 13 are raised by the lifting structure to place the required cavity assembly 3 on the fixed position of the base 1 and fix it. Step two: The lifting mechanism lowers the sandblasting cylinder 4, and the sandblasting cylinder 4 performs sandblasting. Step 3: During the sandblasting process, the front and rear adjustment motor 26 drives the adjustment seat 18 to move back and forth, thereby driving the gear 17 inside the adjustment seat 18 to rotate along the rack inside the adjustment seat 18. The rotation of the gear 17 drives the sandblasting cylinder 4 to deflect in the left and right directions. The left and right adjustment motor 21 drives the adjustment seat 23 to move back and forth, thereby driving the gear 22 inside the adjustment seat 23 to rotate along the rack inside the adjustment seat 23. The rotation of the gear 22 drives the frame 20 to rotate, thereby driving the sandblasting cylinder 4 to deflect in the front and back direction to achieve uniform sandblasting. Step 4: Determine the dimensions of cavity assembly 3. The multi-free robotic arm drives the adjustment plate 13 to move parallel to the central pressure plate 7, and cooperates with the positioning hydraulic cylinder 11 to drive the adjustment plate 13 to align with the central pressure plate 7, and assemble them into an extrusion plate. Step 5: The lifting structure 1 lowers the central pressure plate 7 and the adjusting base plate 13 to the target position. The pressing hydraulic cylinder 1 6 and the pressing hydraulic cylinder 2 12 simultaneously drive the extrusion plates located on both sides of the cavity assembly 3 to extrude and shape the sand mold in the cavity assembly 3.

[0033] All mechanisms in this invention are implemented using existing control systems, and will not be described in detail here.

[0034] Therefore, the present invention employs the above-mentioned vertical parting molding machine and its molding method, which can solve the problem that the existing vertical parting molding machine cannot adjust the size of the positive pressure plate and the negative pressure plate according to the cavity components 3 of different sizes, thereby realizing the molding of sand molds of different sizes.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
