Description
Technical field
The utility model relates to a kind of casting sandbox, especially relates to a kind of batch small articles lost foam casting sandbox.
Background technology
At present, lost foam casting (also known as cavityless casting) is with foamed plastics (EPS, STMMA or EPMMA) macromolecular material make become and the design of part that casting will be produced, the duplicate full mold mould of size, (strengthening is played through dip-coating fireproof coating, bright and clean, permeation functions) and after drying, be embedded in drystone sand through three-dimensional vibrating moulding, casting molding flask pours into molten metal liquid under negative pressure state, make macromolecular material model by thermal evaporation extraction, and then the disposal molding New Casting Technique formed after being replaced cooled and solidified by liquid metals produces the novel casting method of foundry goods.
Lost pattern casting has features: 1, casting quality is good, and cost is low; 2, material is not limit, and size is all suitable; 3, high, any surface finish of precision, minimizing cleaning, saving machine add; 4, internal flaw greatly reduces, and cast structure is fine and close; 5, extensive, production in enormous quantities can be realized; 6, the production in enormous quantities casting of identical foundry goods is applicable to; 7, manual operation is applicable to and automatic assembly line production run controls; 8, the production status of production line meets the requirement of green technology parameter index; 9, greatly can improve working environment and the working condition of foundry production line, reduce labour intensity, reduce energy resource consumption.
Immediate documents application number: the 201320089678.2 a kind of dispellable mould casting sandboxes announced, and application number 201320138523.3 1 kinds of lost foam casting special shape mo(u)lding boxs, number of packages because of casting when above-mentioned sandbox structure is cast to the smallclothes of batch is many, the level of workpiece casting is more, then to the negative pressure pressure value vacuumized and find time to arrange strict requirement.These are all the not available of the vacuum-pumping pipeline of above-mentioned lost foam casting sandbox.Therefore the smallclothes casting of above-mentioned lost foam casting sandbox to batch is also weak.1. traditional sandbox is bleed in five faces, and five faces are double-layer plate and are welded into, and inner plate surface is processed into the mesh of sieve shape, one deck 80 order fine-structure mesh sand control is covered again, this sandbox complex structure on sieve plate, heavy, general all more than 2 tons, maximum shortcoming is that in sandbox, negative pressure is uneven when vacuumizing.
Utility model content
The purpose of this utility model is to provide a kind of batch small articles lost foam casting sandbox, solves traditional sandbox quality and weighs, takes out the uneven problem of negative pressure.
The utility model solves the technical scheme that its technical problem adopts: a kind of batch small articles lost foam casting sandbox, the vacuum-pumping pipeline comprising sandbox body and be arranged in sandbox body, described vacuum-pumping pipeline be connected with run through sandbox body vacuumize interface, it is characterized in that: described vacuum-pumping pipeline comprises horizontal vacuum-pumping tube, longitudinal vacuum-pumping tube, described horizontal vacuum-pumping tube, uniformly on longitudinal vacuum-pumping tube take out hole, described horizontal vacuum-pumping tube is set to 4, described longitudinal vacuum-pumping tube is set to 2, the described interface that vacuumizes is connected with the horizontal vacuum-pumping tube in left side, at all horizontal vacuum-pumping tubes, longitudinal vacuum-pumping tube wraps up one or more layers metal filter opening layer.Described vacuum-pumping tube is pressed matrix pattern distribution and is connected.
The concrete distribution of vacuum-pumping tube, described horizontal vacuum-pumping tube is horizontally set 4 in sandbox body, described longitudinal vacuum-pumping tube longitudinally arranges 4 in sandbox body, each longitudinal vacuum-pumping tube medial surface is connected with the lateral ends of each horizontal vacuum-pumping tube, each longitudinal vacuum-pumping tube and upper, lower horizontal to connecting bending tube head between vacuum-pumping tube, tube connector joint between the horizontal vacuum-pumping tube that each longitudinal vacuum-pumping tube and middle part are arranged.
The beneficial effects of the utility model: 1. this sandbox is individual layer steel plate, fill steel pipe connecting in bottom surrounding and are connected into matrix pattern type, increase negative pressure area.2. the hole number of taking out on the body of matrix pattern structure vacuum-pumping tube is determined by the area of bleeding point, and the area of bleeding of the total sectional area of vacuum-pumping tube is that bleeding point is bled 1.5 times of area.3. this sandbox quality is light, and negative pressure is even, and result is simple, and low cost is easy to maintenance.
Below with reference to drawings and Examples, the utility model is described in detail.
