When the two templates 110 are engaged with each other, the cavity formed by the molding groove 113 is used for molding the wax member 20. When the two templates 110 are buckled, the side sliding seat 220 is pushed by the inclined pushing rod 210 to approach the groove 113, that is, the side sliding seat 220 drives each side sliding piece to slide and extend into the groove 113. When the two templates 110 are separated from each other, the side slide blocks 220 are pushed against the inclined push rods 210 to be away from the grooves 113, so that the side slides are pulled out from the side holes 21 of the molded wax piece 20. Thus, compared with the existing mode of pulling the slide seat 220 manually, the speed of the side sliding piece approaching or separating from the groove 113 is directly determined by the opening and closing speeds of the two templates 110, so that the instability of manual core pulling is effectively avoided, the molding quality of the lateral hole site 21 can be ensured, and the molding efficiency can be improved.
As shown in fig. 2, in one embodiment, the trough 111 includes a main trough 1111 and sub-troughs 1112, each sub-trough 1112 communicates with the main trough 1111, and each sub-trough 1112 communicates with each type of trough 113. Thus, the wax material enters the die plate 110 from the main groove 1111, and then flows into each of the grooves 113 through each of the sub grooves 1112.
In an embodiment, two inclined push rods 210 are provided, two inclined holes 221 are provided, and the two inclined push rods 210 are respectively arranged in the two inclined holes 221 in a penetrating manner. In this way, the side slider 220 is ensured to stably slide relative to the die plate 110, so that each side slider is driven to extend into the groove 113 or slide out of the groove 113.
In one embodiment, two mold closing assemblies 200 are provided, and the two mold closing assemblies 200 are respectively located on two opposite sides of the mold plate 110.

As shown in fig. 2, in one embodiment, the side sliding piece includes two side loose cores 230, and the two side loose cores 230 are disposed on a side wall of the side sliding seat 220 at intervals.
It should be noted that, each cavity (surrounded by the grooves 113 of the two templates 110) forms one wax piece 20, and the wax piece 20 has two lateral holes 21, so each cavity is provided with two side loose cores 230.
As shown in fig. 4, in one embodiment, the side core-pulling device 230 includes a core column 231, a spring 232 and an insert column 233, one end of the core column 231 is disposed on the side sliding seat 220, the other end of the core column 231 is inserted into and clamped to the insert column 233, the spring 232 is sleeved on the outer sidewall of the core column 231, and the spring 232 is respectively abutted with the core column 231 and the insert column 233, and the side sliding seat 220 is used for pushing the insert column 233 to jointly extend into the insert column 113 when being slid close to the insert slot 113.
The above-described structure is provided to avoid deformation of the lateral hole 21 when the side pin 230 is away from the lateral hole 21 of the wax member 20. Thus, when the side sliding seat 220 drives the stem 231 to approach the slot 113, the stem 231 pushes the compression spring 232, and finally the end of the insert 233 and the end of the stem 231 extend into the slot 113 together. After the wax element 20 is formed, the side sliding seat 220 drives the stem 231 to be far away from the mold groove 113, and the stem 233 can temporarily keep a state of unchanged relative position with the mold groove 113 due to the elastic thrust of the spring 232, that is, the stem 231 can slide out relative to the stem 233, so that the center of the stem 233 is kept away, the stem 233 is cooled, the side surface of the stem 233, which is in contact with the wax element 20, is separated from the wax element 20, and the stem 233 slides away from the mold groove 113 along with the stem 231 when the stem 231 slides and blocks the stem 233. Thus, the lateral hole 21 of the wax element 20 is ensured not to be deformed during demolding, and the molding quality is improved.
