Description

A kind of casting with plus sand system

Technical field

The utility model relates to Casting Equipment technical fields, use more specifically to a kind of casting and add sand system.

Background technique

Casting is that the mankind grasp than a kind of metal heat processing technique earlier, has history in about 6000.China about exists Enter the heyday of bronze casting between B.C. 1700~1000 years, has reached quite high level in technique.Casting is Liquid metals is cast in the casting cavity being adapted with part shape, after its cooled and solidified, to obtain part or blank Method.It was mostly originally solid-state but the metal (example: copper, iron, aluminium, tin, lead etc.) for being heated to liquid by casting material matter, and the material of mold Material can be sand, metal even ceramics.Cast blank can reach the mesh for exempting to be machined or process on a small quantity because of almost forming , processing cost is greatly reduced, and reduce Production Time to a certain extent.Currently, casting has become modem devices system Make one of the fundamental technology of industry.

Sand casting refers to using the dry sand of binder free as Modeling Material, and the casting side of casting is produced in sand mold Method, steel, iron and most of non-ferrous alloy castings can all be obtained with sand mould casting method.The Modeling Material as used in sand casting Cheap and easy to get, Casting mold manufacturing is easy, to the single-piece production of casting, produces by batch and mass production adapts to, for a long time, one It is directly the basic technology in Foundry Production.Wherein, sand storage is indispensable mating sand feeding equipment, existing sand in die cast technique Library is usually directly to be arranged valve thereunder, and control valve is opened when work, so that molding sand be made to flow into sandbox.But in use State existing sand storage directly carry out plus sand processing when sand mold sand using amount number can not be controlled, to influence the quality of sand mold.

Through retrieving, has related patents about the sand storage device for carrying out quantitative control to sand feeding amount and disclose, e.g., Chinese patent Application No. is 201220080570.2 application cases to disclose a kind of quick plus sand proportioning device, and this application includes pedestal, master Rack, mainframe are connect by the rocker arm on pedestal with base runner, and cylinder is set between pedestal and mainframe, is set on mainframe Guide rail sets idler wheel on guide rail, and back-and-forth motion cylinder is set on mainframe, and being moved forward and backward cylinder piston boom end and being connected with one can stretch Entering sand storage can be on guide rail through the baffle of idler wheel movement.This application provided with what can be moved on mainframe due to that can stretch The baffle for entering sand storage, in the moulding machine course of work, after molding sand used in sand mold is quickly once filled up, extra sand is by under sand storage Side baffle quickly cut off, with this complete moulding machine quantitatively plus sand program, but using this application device to sand feeding amount It is relatively low to control precision.

For another example, the application case that China Patent No. is 201720875177.5 discloses a kind of casting sanding device, this application Case includes frame body, and the upper end of frame body is fixed with storage sand warehouse, and the lower section for storing up sand warehouse is equipped at least two plus sand bucket, and respectively plus sand bucket is solid It is scheduled on frame body, respectively plus the feed inlet of sand bucket passes through the discharge port that sand warehouse is stored up in its corresponding feeding-passage connection, and each charging is logical Inlet valve is equipped on road, respectively plus sand bucket is transparent material, respectively plus in the outer webs of sand bucket is equipped with graduation mark, respectively plus sand bucket Bottom be equipped with plus sand mouth, respectively plus on sand mouth be equipped with outlet valve, respectively plus the bottom of sand mouth is respectively connected with plus sandpipe.This application Case on adding sand bucket by being arranged graduation mark, to accurately control pre- sand feeding amount, prevents dry sand and fills out more or fill out less and shadow Casting quality is rung, but can only realize the control of sand feeding amount when sand is expected up at the scale for adding sand bucket.
