[0027] When the upper mold 1 and the lower mold 2 are closed, an external force pushes the upper mold 1 to drive the bottom plate 3 to move toward the lower mold 2 until the upper mold 1 and the lower mold 2 are axially symmetrically arranged on the bottom plate 3 along the vertical direction, so that the bottom plate insert 4 is accommodated in the first accommodating groove 11 and the second accommodating groove 21, and the iron core 5 is accommodated in the iron core accommodating groove 6. After the upper mold 1 and the lower mold 2 are closed, a wax injection hole 7 is formed on the side, and the wax injection hole 7 is connected to the first cavity 12 and the second cavity 22 respectively.

[0028] A first wax injection hole is provided on the upper side of the upper mold 1, and a second wax injection hole is provided on the upper side of the lower mold 2. The first wax injection hole and the second wax injection hole are axially symmetrically arranged.

When the bottom plate insert 4 is accommodated in the first accommodating groove 11 and the second accommodating groove 21, the iron core 5 is accommodated in the iron core accommodating groove 6. After the mold is closed, wax is injected into the wax injection hole 7 to allow the wax raw material to enter the first cavity 12 and the second cavity 22. After the wax injection is completed, the equipment controls the upper mold 1 and the lower mold 2 to separate, and the manipulator takes out the wax mold and the iron core 5 together. Since the upper mold 1 and the lower mold 2 are placed vertically, the wax injection equipment has enough space to accommodate the manipulator to participate in the wax injection process. There is no need to manually place the iron core 5 and take out the wax mold, which improves the work efficiency of the wax injection.

[0031] Optionally, the shapes and sizes of the positioning block 42 and the positioning block accommodating groove 32 are adapted to each other, the positions, shapes and sizes of the positioning hole 44 and the fixing hole 33 are adapted to each other, the positioning hole 44 and the fixing hole 33 can be circular or square, and the number of the positioning holes 44 and the fixing holes 33 is at least 2, and can also be set to 3, 4 or more according to actual needs.

[0032] When the bottom plate insert 4 is installed on the bottom plate 3, the positioning block 42 is first placed in the positioning block receiving groove 32, so that the bottom plate 3 cannot be easily moved on the horizontal plane. At this time, the positioning hole 44 and the fixing hole 33 are aligned in the vertical direction. At this time, the fixing piece is inserted into the positioning hole 44 and the fixing hole 33 in sequence to fix the bottom plate insert 4 on the bottom plate 3. When the bottom plate insert 4 needs to be removed from the bottom plate 3, the fixing piece can be taken out from the positioning hole 44 and the fixing hole 33 in sequence, and the disassembly is completed quickly.

[0033] In one embodiment, notches 311 are axially symmetrically provided at both ends of the base 31, so that a convex block 312 is formed in the middle of the base 31; grooves 23 matching the convex block 312 are provided at the bottom of the upper mold 1 and the lower mold 2.
