Quick combination device with external riser for shell mold casting process

Abstract

The invention relates to a riser external connection type rapid combination device for a shell mold casting process, which comprises an upper closing plate and a locking mechanism, the lower end wall of the upper closing plate is provided with a slideway, the top end of the middle part of the upper closing plate is provided with a lock cylinder mechanism, the locking mechanism is arranged on the top end side of the upper closing plate, and the lower end of the upper closing plate is provided with a lower closing plate; a position adjusting screw rod is arranged between the upper closing plate and the lower closing plate, a plate closing opening is formed in the middle of the lower closing plate, a plate group mechanism is installed at the inner side end of the plate closing opening, containing holes are formed in the left end wall and the right end wall of the upper closing plate, interlocking wires are arranged at the inner side ends of the containing holes, and temperature conducting pieces are fixed to the lower end walls of the interlocking wires. The riser external connection type rapid combination device for the shell mold casting process has the beneficial effects that the positions of the connecting strips are adjusted through movement between the assembly pieces and the connecting strips, then the cover pieces at the top ends of the connecting strips are linked to conduct position adjustment, extension and expansion are facilitated, the riser external connection type rapid combination device is better connected with a riser of the forging process in a matched mode, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of casting technology, in particular to a riser external fast coupling device for shell casting technology. Background technique [0002] When the shell mold casting process needs to use heating and heat preservation risers, the general design of riser positioning is always unsatisfactory, the mold parting is unreasonable, the riser neck is not easy to cut, and the work of artificially covering the leak-proof plate is increased, and the cost is correspondingly increased. When the riser is processed and assembled, it often needs to be positioned and locked, so a combined locking device is required to facilitate the processing and assembly of the riser. [0003] Due to the fact that the end of the existing riser joint device is not designed with a good movable docking structure, the end cannot be adjusted, and the distance between the various parts will be changed, resulting in poor adaptability during use.

Problems solved by technology

[0004] The object of the present invention is to provide a kind of riser external connection type fast coupling device for shell mold casting technology, to solve the existing riser coupling device proposed in the above-mentioned background technology because its end is not designed with a better movable butt joint structure, As a result, the end cannot be adjusted freely, and the distance between the various parts can be changed, resulting in poor adaptability when used. At the same time, the joint device cannot firmly snap and lock the riser, nor can it assemble the riser. part of the heating, it is difficult to improve its molding efficiency
