Abstract
The invention discloses a high-efficiency lost foam casting production line. Sand boxes are arranged on a sand box circulation loop system in a stepping circulation mode, a casting machine casts the sand boxes which are stepped to casting section rails of the sand box circulation loop system, stop section rails are parallel to the casting section rails of the sand box circulation system, and the middle parts of the casting section rails and the stop section rails are connected through ferry trolleys; the sand boxes are subjected to handover operation on the casting section rails and the stop section rails; and the movable casting machine is arranged on a casting machine rail parallel to the casting section rails and performs movable casting back and forth, so that two sections of sand boxes are alternately cast by one movable casting machine on one straight rail. Molding and casting cannot influence each other on the production line.
Description
Technical field
The present invention relates to a kind of casting system, especially a kind of efficient lost foam casting production line.
Background technology
At present, in the lost foam casting industry, generally use crane allocation and transportation pouring ladle pouring cast part.But the lost foam casting production line that each bar is advanced is equipped with the technological increasing of a portable casting machine cast.Because the lost foam casting sandbox generally will be poured into a mould under negative pressure state, just need extract the air in the inner sand grains of the sandbox gap out a part, make the sandbox internal pressure be lower than external air pressure; Promptly form negative pressure, be called as vacuum-assist pouring, generally fix on the ground owing to take out the pipeline of negative pressure; And the joint that docks with sandbox can move a very little distance; Be adjacent to sealed butt joint with the negative pressure interface of taking out on the sandbox, take out vacuum-assist pouring after the butt joint, sandbox can not move.This is the current techique of lost foam casting.Use the production line of portable casting machine that following several kinds of situation are arranged: first kind of lost foam casting production line, the sandbox circulation has only " mouth " font loop, and this is modal a kind of lost foam casting production line.This production line is poured into a mould taking out under the situation of negative pressure, and in time a few minutes before the casting solidification, the sandbox that has just been poured can not move during cast or behind the casting complete.Therefore, all sandboxes all can not move in stepping.Moulding must hocket with cast.Can only realize being interrupted moulding.Second kind of lost foam casting production line; The sandbox cyclic design has become " day " font, has two closed circuits, and cast can be carried out at two row sandboxes arranged side by side; Though can realize moulding and cast does not influence; But each portable casting machine can only be accomplished the cast of a row sandbox, and another row sandbox also will dispose a casting machine or pour into a mould with the crane for hoisting pouring ladle.The third lost foam casting production line, having designed a kind of negative pressure device of taking out can be when the sandbox stepping and the same moved further of sandbox, and casting machine is followed the tracks of sandbox and is accomplished cast.Though can realize the uninterrupted moulding of production line like this,, this specification requirement is taken out the pipe joint and the sandbox of negative pressure and is wanted same moved further, and casting machine and sandbox are also wanted same moved further.This is just higher to the requirement of equipment, makes equipment more complicated, and because sandbox and casting machine are followed the tracks of multiple reasons such as bad synchronously, often causes cast to be interrupted, and brings influence to casting quality, even scraps.Therefore, be difficult to obtain implement.
Summary of the invention
The technical problem that the present invention will solve has provided a kind of efficient lost foam casting production line of continuously-running; Two sandbox closed circuits have been adopted; Two sections cast section tracks are located along the same line; Only adopt a packaged type casting machine on the straight line track, to move, just can accomplish whole cast.Realize that moulding, cast, mould turnover are independent of each other.
For solving the problems of the technologies described above; The technical scheme that the present invention taked is: its step cycle in sandbox closed circuit system has sandbox; Casting machine is poured into a mould the sandbox on the cast section track that steps to sandbox closed circuit system; It is characterized in that: the cast section track of the said sandbox circulatory system is set side by side with stops the section track, and cast section track is realized being connected through the ferry-boat dolly with the middle part of stopping the section track; Described sandbox is at cast section track and stop handing-over operation on the section track; Described casting machine moves forward and backward cast along the casting machine track.
After adopting above-mentioned structure, sandbox just has two running routes at a cast section track and a stop section track: 1, cast section track leading portion-ferry-boat dolly-stop section track back segment; 2, stop section track leading portion-ferry-boat dolly-cast section track back segment.When casting machine is poured into a mould the sandbox on cast section track leading portion or the back segment like this (sandbox of being poured into a mould remains static), the stepping that can not influence another running route cope is moved.
The sandbox circulatory system of the present invention is enclosed by moulding section track 4, cast section track 8,13 and stop section track 20,16, the first ferry-boat dolly 14, cooling section track 19 and the second ferry-boat dolly 23 and forms; Described moulding section track 4 is the single channel structure; Cast section track (8,13) with stop a section track (20,16) and form two line structures, moulding section track 4 and cast section track (8,13) join through the 3rd ferry-boat dolly 7 and the 4th dolly 11 of ferrying joins with stopping between the section track (20,16).
On the casting machine track 12 that casting machine 9 section of being arranged on and pouring into a mould tracks 8,13 of the present invention laterally arrange.
Cooling section track 19 of the present invention is the single channel structure.
Sandbox closed circuit of the present invention system realizes that by pushing away case apparatus 1,6,10,15,18,22 steppings of sandbox in sandbox closed circuit system move.
A cast section track 8,13 of the present invention and a stop section track 20,16 all can be arranged 10～30 sandboxes are set.
Adopt the beneficial effect that technique scheme produced to be: the present invention can realize that the moulding of whole lost foam casting production line, cast do not pin down mutually.Only use a portable casting machine to go up two sections sandboxes are replaced cast respectively at straight line track (casting machine track).When the sandbox section of being poured into a mould remains static, and another closed circuit sandbox can be realized mould turnover, the stepping of moulding pusher case, realizes block sequences.Realized that mould turnover, moulding, cast are independent of each other.Only improve one times nearly than present with the efficient of the lost foam casting production line of a portable casting machine cast.
