Description
Technical Field
The invention relates to a device for punching through a blind hole of a sand mold for casting, belonging to the field of industrial casting production.
Background
The sand mold produced in the casting industry needs to form vent holes for discharging gas generated in the molten iron pouring process, at present, blind holes are formed in the sand mold firstly, and the blind holes are punched in a hole pricking or hole drilling mode in the subsequent production process.
In the prior art, the following two modes are mostly adopted to open blind holes in a sand mold, one mode is to open the blind holes upwards from the back surface of the sand mold, the other mode is to open the blind holes downwards from the inside of the sand mold, the former technology is easy to butt joint and dislocate when opening the blind holes, and sand is easy to remain in air holes, when the latter technology is used to open the blind holes, the back surface of the sand mold can be cracked and collapsed by sand, the back surface of the air holes can be easily formed with the phenomena of inverted bell mouth, pit and the like, and molten iron can be easily poured into the air inlet holes from the place during pouring.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: to the not enough of prior art existence, provide a casting with device of getting through sand mould blind hole, can effectively get through a plurality of blind holes from the inside disposable of sand mould to avoid the sand mould back to prick out the horn mouth of falling and prevent pouring backward when the molten iron pouring, promoted work efficiency by a wide margin.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention provides a device for punching through a sand mold blind hole for casting, which comprises an oil cylinder, a gas eye needle fixing plate connected with the oil cylinder, a lower top plate and a lifting device, wherein the cleaning device is connected with the lower top plate; the oil cylinder pushes the gas eye needle fixing plate to move from top to bottom, and the lifting device lifts the upper top plate up and down; the air hole needle fixing plate is vertically fixed with an air hole needle, and the lower top plate is provided with a preformed hole corresponding to the air hole needle.
Specifically, the air hole needle fixing plate and the lower top plate are made of non-metal materials such as nylon and the like in a machining mode.
Specifically, cleaning device can remove about roof top down, and with roof contact down, clears up roof surface down, guarantees that roof can paste at the sand mould back accurately and smoothly down.
Specifically, the air hole needle corresponds to the position of the blind hole in the sand mold, and can be correspondingly adjusted according to the position and the number of the blind holes in the sand mold
Specifically, the air hole needle vertically fixed on the air hole needle fixing plate can be tightly attached to the reserved hole arranged on the lower top plate when the oil cylinder pushes.
Specifically, the lower top plate can be tightly attached to the back of the sand mold when the lifting device is lifted.
After the air hole is communicated, the air pricking needle returns to the original position, and the lower top plate also returns to the original position. Scattered sand on the lower top plate is cleaned by the side cleaning brush, so that the lower top plate can be accurately and flatly attached to the back of the sand mold.
Compared with the prior art, the invention has the beneficial effects that: optimize the process of getting through of sand mould blind hole, can prevent to leave the residual sand in the gas pocket and lead to the foundry goods waste product, can avoid the back to form the mouth of falling a horn again, can also prevent to flow backward when the molten iron pouring from influencing the pouring quality, the cleaning device who arranges simultaneously can clean the scattered sand of roof down after the work is accomplished, guarantees that roof can accurately paste smoothly at the sand mould back down.
