[0029] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0030] like Figures 1 to 3 As shown, a wax mold forming mold 10 that is easy to demold, includes a snap-fit ​​assembly 100 and a closed mold assembly 200, the snap-fit ​​assembly 100 includes two templates 110, one side of the template 110 is provided with a material trough 111, a plurality of slide grooves 112 and a plurality of spaced-apart grooves 113, each groove 113 is connected to the material trough 111, each slide groove 112 is respectively connected to each groove 113, and each slide groove 112 extends to the outer side wall of the template 110 in a direction away from the material trough 111, the closed mold assembly 200 includes an inclined push rod 210, a side slide seat 220 and a plurality of side slide members, the inclined push rod 210 is arranged on one of the templates 110, and the side sliding seat 220 is slidably arranged on the other template 110. The side sliding seat 220 is provided with an inclined hole 221. Each side sliding member is arranged on the side sliding seat 220, and a partial structure of each side sliding member is respectively accommodated in the slide groove 112. When the two templates 110 are buckled with each other, the two material troughs 111 together form a material cavity, the two molding grooves 113 together form a molding cavity, and the two sliding grooves 112 together form a slideway, and the inclined push rod 210 pushes the inner side wall of the inclined hole 221, so that the side sliding seat 220 drives each side sliding member to extend into each molding cavity respectively.

[0031] It should be noted that when the two templates 110 are buckled together, the cavity formed by the mold groove 113 is used to mold the wax part 20. As the two templates 110 are buckled together, the side slide seat 220 is pushed up by the inclined push rod 210 to approach the mold groove 113, that is, the side slide seat 220 drives each side slide member to slide into the mold groove 113. When the two templates 110 are separated from each other, the side slide seat 220 is pushed up by the inclined push rod 210 in the opposite direction to move away from the mold groove 113, so that each side slide member is pulled out from the lateral hole position 21 of the molded wax part 20. In this way, compared with the existing method of manually pulling the side slide seat 220 for core pulling, the speed of the side slide member approaching or moving away from the mold groove 113 in the present application is directly determined by the opening and closing speeds of the two templates 110, which effectively avoids the instability of manual core pulling, thereby ensuring the molding quality of the lateral hole position 21 and improving the molding efficiency.

[0032] like Figure 2 As shown, in one embodiment, the material tank 111 includes a main tank 1111 and sub-tanks 1112, each sub-tank 1112 is connected to the main tank 1111, and each sub-tank 1112 is respectively connected to each mold groove 113. In this way, the wax material enters the template 110 from the main tank 1111, and then flows into each mold groove 113 through each sub-tank 1112.

[0033] In one embodiment, two inclined push rods 210 are provided, two inclined holes 221 are provided, and the two inclined push rods 210 are respectively inserted into the two inclined holes 221. In this way, it is ensured that the side sliding seat 220 can stably slide relative to the template 110, thereby driving each side sliding member to extend into the groove 113, or slide out of the groove 113.

[0034] In one embodiment, two mold closing assemblies 200 are provided, and the two mold closing assemblies 200 are respectively located on opposite sides of the template 110. It should be noted that in order to further improve the molding efficiency of the wax piece 20, a mold closing assembly 200 is respectively provided on the opposite sides of the template 110, and correspondingly, a plurality of molding grooves 113 are provided on the opposite sides of the material trough 111, so that a plurality of wax pieces 20 can be molded at the same time to improve production efficiency.

[0035] like Figure 2 As shown, in one embodiment, the side slide member includes two side pull cores 230 , and the two side pull cores 230 are disposed on a side wall of the side slide seat 220 at intervals.

[0036] It should be noted that each cavity (enclosed by the grooves 113 of the two templates 110 ) forms a wax piece 20 , and the wax piece 20 has two lateral holes 21 , so each cavity is provided with two side core pulls 230 .

[0037] like Figure 4As shown, in one embodiment, the side core pull 230 includes a core column 231, a spring 232 and an insert column 233. One end of the core column 231 is set on the side sliding seat 220, and the other end of the core column 231 is passed through and clamped on the insert column 233. The spring 232 is sleeved on the outer wall of the core column 231, and the spring 232 is respectively in contact with the core column 231 and the insert column 233. The side sliding seat 220 is used to slide close to the groove 113 so that the core column 231 pushes the insert column 233 to extend into the groove 113 together.

[0038] It should be noted that the above structure is provided to prevent the lateral hole 21 from deforming when the side core pull 230 is away from the lateral hole 21 of the wax piece 20. Thus, when the side sliding seat 220 drives the stem 231 to approach the groove 113, the stem 231 pushes the compression spring 232, and finally the end of the insert 233 and the end of the stem 231 are extended into the groove 113 together. When the wax piece 20 is formed, the side sliding seat 220 drives the core column 231 away from the groove 113. Due to the elastic thrust of the spring 232, the inlay column 233 temporarily maintains a relative position unchanged with the groove 113, that is, the core column 231 slides out relative to the inlay column 233, so that the center of the inlay column 233 is vacant, the inlay column 233 cools, and the side of the inlay column 233 that contacts the wax piece 20 falls off from the wax piece 20. As the core column 231 slides and clamps the inlay column 233, the inlay column 233 follows the core column 231 to slide away from the groove 113. In this way, it is ensured that the lateral hole 21 of the wax piece 20 will not be deformed during demolding, thereby improving the molding quality.

[0039] like Figure 4 As shown, in one embodiment, a first step 2331 is provided on the inner wall of the insert column 233 , a second step 2311 is provided on the outer wall of the core column 231 at one end of the insert column 233 , and the first step 2331 is used to clamp the second step 2311 .

[0040] It should be noted that, in this way, when the core column 231 slides relative to the embedded column 233 so that the first step 2331 is engaged with the second step 2311 , the core column 231 will drive the embedded column 233 to slide out of the groove 113 to achieve demoulding.

[0041] like Figure 4 As shown, in one embodiment, an inner conical surface is provided on the inner side wall of the insert column 233, and an outer conical surface is provided on the outer side wall of the core column 231 located at one end of the insert column 233, and the outer conical surface is used to adaptively push the inner conical surface. In this way, when the outer conical surface adaptively pushes the inner conical surface, it means that the core column 231 and the insert column 233 are both extended into the mold groove 113 to complete the mold closing operation.

[0042] like Figure 5As shown, in one embodiment, the wax model forming mold 10 for easy demolding also includes a seat 310 and a vibrator 320. The template 110 close to the side sliding seat 220 is also provided with a plurality of inlay holes, each of which is respectively located on the bottom wall of each groove 113. A plurality of inlay blocks 330 are arranged on the seat 310. The seat 310 is arranged on a side surface of the template 110 away from the groove 113 so that each inlay block 330 can be respectively accommodated in each inlay hole. The vibrator 320 is arranged on a side surface of the seat 310 away from the template 110.

[0043] It should be noted that, in order to further improve the demoulding effect of the wax piece 20, an insert 330 is provided on the bottom wall of the groove 113, wherein the insert 330 is located on the seat 310. In one embodiment, the seat 310 and the insert 330 are an integrally formed structure. A vibrator 320 is fixedly installed on a side surface of the seat 310 away from the insert 330. In this way, when the two templates 110 are separated, the vibrator 320 vibrates, and the wax piece 20 can be quickly vibrated off from the inner side wall of the groove 113 to achieve demoulding. Among them, the vibrator 320 can be a vibrator on the market, as long as it can generate vibration.

[0044] like Figure 1 and Figure 5 As shown, in one embodiment, the wax mold forming mold 10 for easy demolding further includes a bottom plate 340 , which is disposed on a side surface of the template 110 close to the mounting seat 310 , so that the vibrator 320 is located between the bottom plate 340 and the template 110 .

[0045] It should be noted that the template 110 is fixedly mounted on the bottom plate 340 by bolts, and there is a gap between the bottom plate 340 and the template 110, and the vibrator 320 is located between the bottom plate 340 and the template 110. In one embodiment, a U-shaped hole is opened on the bottom plate 340, so that the bottom plate 340 can be fixed on the wax injection machine by bolts.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
