Description

Technical Field

[0001] The utility model relates to the field of equiaxed crystal vacuum precision casting, in particular to an equiaxed crystal mold shell positioning casting tool. Background Art

[0002] In the current field of equiaxed vacuum precision casting, after the mold shell is baked to the required temperature, the mold shell must be quickly and accurately positioned and placed on the pouring platform to complete the pouring process. This link is crucial to ensure the quality of castings and reduce the defective rate.

[0003] For some small and light molds, the industry generally uses a suspended hanger to position them. This method is simple, effective and easy to operate. However, when faced with large and heavy molds, the traditional suspended hanger method is inadequate. Due to the impact force of the alloy liquid and its own gravity during the pouring process, coupled with the limited structural strength of the pouring cup, the stability of the mold after pouring is often greatly reduced. In actual operation, the mold often falls off or topples from the hanger, which not only seriously affects the accuracy of pouring and the quality of castings, but may also cause production safety accidents.

[0004] At present, in order to solve the problem of positioning pouring of large-volume molds, a new type of positioning pouring tooling is urgently needed, which can stably support and position the large-volume molds to ensure the smooth progress of the pouring process and ultimately improve the quality and yield rate of castings. Utility Model Content

[0005] Based on the problems existing in the above-mentioned prior art, the utility model aims to effectively solve the challenges faced by large-volume molds during positioning and pouring by combining an innovative positioner with a base. In this way, not only can the mold be firmly positioned, but it can also effectively prevent the mold from falling or dropping during the pouring process, thereby greatly improving production efficiency and product quality.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is to design an equiaxed crystal mold shell positioning casting tool, including a base and a positioner, the base is used to place the mold shell to be processed, and the positioner is used to determine the casting position.

[0007] Furthermore, the base includes a bottom plate, which is used to place the mold shell. A circle of fence is arranged on the bottom plate, and an opening is left on one side of the fence to facilitate the movement of the mold shell.

[0008] Furthermore, the bottom plate is provided with a thermal insulation cotton belt surrounded by a plate material, and thermal insulation cotton is arranged in the middle of the thermal insulation cotton belt.

[0009] Preferably, the thermal insulation cotton belt is folded from a thin plate with a thickness of 1.5 mm.

[0010] Furthermore, a plurality of supporting legs are provided at the lower part of the base plate.

[0011] Preferably, the supporting legs are made of mesh tube material.

[0012] Furthermore, the positioner includes a positioning ring, a positioning rod and a holding rod. The holding rod is arranged at the rear end of the positioning ring. The positioning rods are respectively arranged around the positioning ring. The connecting ends of the positioning rod and the positioning ring are hollow round rods, and an adjusting rod is sleeved inside. The adjusting rod extends and retracts in the positioning rod to realize the relative positioning of the positioning ring.

[0013] Preferably, the size of the positioning ring is consistent with the size of the mold shell pouring cup.

[0014] Furthermore, there are three positioning rods, which are respectively arranged around the positioning ring at an angle of 90°.

[0015] Furthermore, a fixing bolt is provided on the positioning rod, and the fixing bolt controls the extension length of the adjusting rod through threaded tightening.

[0016] Preferably, the gripping rod is a cylinder with a wall thickness of 2 mm and a diameter of 30 mm.

[0017] Preferably, the positioning rod is a hollow cylinder with a wall thickness of 1 mm and a diameter of 10 mm, and the adjusting rod is a solid cylinder with a diameter of 6 mm.

[0018] The advantages and beneficial effects of the utility model are as follows: through the combined use of the base and the positioner, the mold shell no longer needs to be suspended, thereby completely eliminating the risk of the mold shell falling or falling after pouring, and significantly improving the safety of the production process. The positioner is exquisitely designed and simple to operate, and can quickly and accurately determine the pouring position, thereby improving work efficiency. At the same time, the mold shell is placed directly on the base, making the operation more convenient. Once the initial positioning is completed, the positioner can be directly used for verification for subsequent pouring of similar mold shells. When the position is not suitable, the pouring position can be easily adjusted by moving the base, which greatly enhances the flexibility and repeatability of the operation.

[0036] Specific steps:

[0037] Before pouring, first place the cold mold on the base 1, and raise it to the pouring position of the smelting chamber through the large shaft for adjustment. After the induction coil is flipped from the vertical state to the horizontal position, the operator visually ensures that the position of the mold on the base is accurate. Subsequently, the mold is lowered to the ingot mold chamber, and the positioning ring 21 of the positioner 2 is used to tightly cover the outer diameter of the pouring cup of the mold. Find three fixed positioning points on the inner wall of the ingot mold chamber, and then tighten the three adjustment rods 24 to complete the positioning setting. When the hot mold that has been baked into place is placed on the base 1, the operator can use the pre-adjusted positioner 2 to verify whether the position of the mold is consistent with the previous setting. If a deviation in the position is found, the base 1 can be moved to make corresponding adjustments to ensure the accuracy of the pouring and the quality of the casting.
