Description

Technical Field

[0001] The utility model relates to the technical field of investment casting pouring cups, and particularly relates to an assembly device for the middle column rod of a pouring cup. Background Art

[0002] In the pouring process of the investment casting field, a pouring cup is required to pour molten metal. In the shell-making stage of the mold assembly, the pouring cup and the middle column rod need to be assembled in advance. After the middle column rod vertically penetrates through the pouring cup, the pouring cup and the middle column rod are bonded together with hot wax. This is convenient for the lower end of the middle column rod to be inserted into the hole on the mold for positioning during the subsequent assembly of the pouring cup, ensuring the coaxiality of the pouring cup. After assembly, the wax is melted in the dewaxing area, and the middle column rod is pulled out upwards. It can be seen that the coaxiality of the assembly of the pouring cup and the middle column rod directly affects the quality of the mold assembly. At present, when assembling the pouring cup and the middle column rod, it is necessary to visually inspect and continuously fine-tune manually after pouring the wax, so as to adjust the coaxiality of the pouring cup and the middle column rod. Affected by different personnel or different states of personnel, the coaxiality is difficult to guarantee, and the error lacks consistency and regularity. In addition, during the transfer after assembly, the pouring cup is located on the long middle column rod and is prone to bumping against external entities, resulting in damage. Summary of the Utility Model

A plurality of first positioning holes 4 are formed in the first positioning plate 2, and a plurality of second positioning holes 5 are formed in the second positioning plate 3. Each second positioning hole 5 corresponds to and is coaxial with a first positioning hole 4. The size of the first positioning hole 4 matches the small end of the sprue cup 20, and the size of the second positioning hole 5 matches the diameter of the middle column rod 21.

[0035] Principle:

[0036] When assembling the sprue cup 20 and the middle column rod 21, first insert the small end of the sprue cup 20 downward into the first positioning hole 4 of the first positioning plate 2 to keep the sprue cup 20 vertical. Then insert the middle column rod 21 into the sprue cup 20, and insert the lower end of the middle column rod 21 into the second positioning hole 5 of the second positioning plate 3. Use the second positioning hole 5 and the sprue cup 20 to jointly limit the position, so that the middle column rod 21 remains vertical. After that, pour hot wax into the sprue cup 20. After the hot wax cools, the middle column tube and the sprue cup 20 can be bonded together, that is, the assembly is completed. After the assembly is completed, the whole box can be carried by the box body 1 to the next process and taken out directly for assembly during the module assembly, avoiding the collision and damage of the sprue cup 20 during transportation.

[0037] Note: Matching means that the diameter of the hole is the same as the small end of the sprue cup 20 or the diameter of the middle column rod 21. The sprue cup 20 or the middle column rod 21 can just be inserted into the hole and contact with the inner wall of the hole to form coaxial limit.
