[0001] The utility model relates to the technical field of mold processing, in particular to a deformation prevention control device for a resin investment mold with a regular shape. Background Art

[0002] In the prior art, resin investment molds are printed separately or arranged in the same direction. There is no restriction for the resin investment mold printed separately, and it is extremely easy to deform; for two resin investment molds arranged in the same direction, although there is a simple thin pull rod between them, because they are arranged in the same direction, the forces generated by the deformation of each resin investment mold are all in the same direction, and there is no restraining force, so the deformation problem cannot be effectively controlled. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and provide a deformation prevention control device for a resin investment mold with a regular shape, including:

[0004] Two resin investment molds arranged non - coaxially and a fixing rod connecting the two resin investment molds;

[0005] Wherein, the fixing rod includes a load - bearing section and support sections arranged at both ends of the load - bearing section, and the non - connected ends of the two support sections are respectively connected to the two resin investment molds.

[0006] Further, both the load - bearing section and the support sections are cylindrical; the load - bearing section and the support sections are coaxially arranged; the outer diameter of the load - bearing section is larger than the outer diameter of the support sections.

[0007] Further, the outer diameter of the support section is 1 - 5 mm less than the wall thickness of the resin investment mold.

[0008] Further, a single resin investment mold has an arched structure, the two resin investment molds are arranged back - to - back, and the two ends of the fixing rod are respectively connected to the outer walls of the two resin investment molds.

[0009] Further, the two resin investment molds are arranged facing each other, and the two ends of the fixing rod are respectively connected to the inner walls of the two resin investment molds.

[0010] Further, the fixing rod is designed as an integral structure.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. For the deformation prevention control device of a resin investment mold with a regular shape of the utility model, the two resin investment molds are arranged facing each other or back - to - back, and there is a fixing rod between them. The fixing rod exerts a pulling force or a pushing force on the two non - coaxially arranged resin investment molds during deformation, which can greatly prevent the resin investment mold from deforming.

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figure 1-2 , the technical solution of an anti-deformation control device for a resin investment casting with a regular shape provided in this embodiment is as follows: including:

[0026] Two resin investment castings 1 arranged non-parallel and a fixed rod 2 connecting the two resin investment castings 1;

[0027] Wherein, the fixed rod 2 includes a load-bearing section 21 and support sections 22 provided at both ends of the load-bearing section 21, and the ends of the two support sections 22 that are not connected to the load-bearing section 21 are respectively connected to the two resin investment castings 1.

[0028] Preferably, the circular column has no corners. Therefore, when subjected to pressure or tension, the stress distribution is more uniform, avoiding stress concentration caused by corners. This uniform stress distribution makes the circular column more efficient in utilizing material strength. Therefore, both the load-bearing section 21 and the support section 22 are set to be columnar. In order to evenly transfer the force to the entire fixing rod 2, the load-bearing section 21 and the support section 22 are coaxially arranged. The existing pull rod between two adjacent resin investment molds 1 is a whole cylindrical rod with the same diameter, and the strength of this structure of the pull rod is insufficient. In order to ensure the strength of the fixing rod 2, the outer diameter of the load-bearing section 21 is set to be larger than the outer diameter of the support section 22.

[0029] Specifically, in order to prevent the fixing rod 2 itself from having excessive shrinkage due to its large size, which may cause deformation of the resin investment mold 1, only the outer diameter of the support section 22 is made 1 - 5 mm smaller than the wall thickness of the resin investment mold 1, so that the shrinkage force of the fixing rod 2 is almost equal to the deformation force of the resin investment mold 1.

[0030] In one embodiment, a single piece of the resin investment mold 1 has an arched structure, and two pieces of the resin investment mold 1 are arranged back to back. The two ends of the fixing rod 2 are respectively connected to the outer walls 11 of the two pieces of the resin investment mold 1. The fixing rod 2 is provided with at least two groups, and each group contains at least two fixing rods 2. In order to avoid deformation to the greatest extent, the two groups of fixing rods 2 are respectively arranged at the edges of the gap between the two pieces of the resin investment mold 1 arranged back to back, that is, the two groups of fixing rods 2 are respectively connected to the edges of the outer walls 11 of the two pieces of the resin investment mold 1. The two fixing rods 2 in a single group are respectively connected to the upper and lower ends of the edge of the outer wall 11 of the resin investment mold 1. When the two ends of the arched resin investment mold 1 deform and shrink towards the center of its own circle, the fixing rod 2 generates a tensile force on the two ends of the resin investment mold 1 to prevent deformation.

[0031] In one embodiment, a single piece of the resin investment mold 1 has an arched structure, and two pieces of the resin investment mold 1 are arranged facing each other. The two ends of the fixing rod 2 are respectively connected to the inner walls 12 of the two pieces of the resin investment mold 1. Similarly, the fixing rod 2 is provided with at least two groups, and each group contains at least two fixing rods 2. In order to avoid deformation to the greatest extent, the two groups of fixing rods 2 are respectively arranged at the edges of the gap between the two pieces of the resin investment mold 1 arranged facing each other, that is, the two groups of fixing rods 2 are respectively connected to the edges of the inner walls 12 of the two pieces of the resin investment mold 1. The two fixing rods 2 in a single group are respectively connected to the upper and lower ends of the edge of the inner wall 12 of the resin investment mold 1. When the two ends of the arched resin investment mold 1 deform and shrink towards the center of its own circle, the fixing rod 2 generates an outward thrust on the two ends of the resin investment mold 1 to prevent deformation.

[0032] In one embodiment, the resin investment mold 1 can also be mass-produced in batches. Here, for the sake of easier understanding, taking the orientation of the inner wall 12 of the resin investment mold 1 as an example, a row of resin investment molds 1 can be arranged in the pattern of left-facing - right-facing - left-facing - right-facing in sequence, so as to ensure that any two adjacent resin investment molds 1 are arranged face to face or back to back. Only in this arrangement can the fixing rod 2 generate a supporting force or a pulling force when the two adjacent resin investment molds 1 deform, preventing deformation.

[0033] Specifically, the fixing rod 2 is designed with an integrated structure.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
