Abstract
The invention relates to the technical field of automobile parts making, in particular to a method for molding a twin-bridge auto balance suspension leaf-spring seat through vacuum negative pressure. Compared with the prior art, in the method of the invention, based on the principle of vacuum negative pressure, a feeder head is arranged on a middle boss processing side so as to conveniently exhaust, uniformly feed and increase the density of casting; a 0.15mm EVA casting film can ensure the good integrity of a laminating film cavity; and the mixed composition, which is formed by mixing alcohol, glue and 280 meshes quartz sand, can form a coating layer after being dried, so as to efficiently prevent the sand burning phenomenon on the casting surface, ensure the good surface finish quality of the casting, reduce the processing processes, simplify the operation and greatly lower the manufacturing cost.
Description
Technical field
The present invention relates to auto parts manufacturing technology field, particularly a kind of doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method.
Background technology
Doube bridge automobile balance suspension sand mold spring block is after moulding in the prior art, and the cast(ing) surface outward appearance is coarse, needs further processing, adopts this foundry engieering to exist a lot of defectives, as increasing processing technology, increases manufacturing cost, shortcomings such as poor product quality.
Summary of the invention
For solving existing defective of automobile balance suspension plate spring abutment moulding and problem in the prior art, provide a kind of doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method.
The technical scheme that the present invention is adopted for its technical problem of solution is: doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method of the present invention comprises the whole mold of a spring block, the whole mold of spring block divides the upper and lower mould casting, in the endoporus of the whole mold of spring block is the disjunctor core, the whole mold boss of spring block is provided with one and begins to crop up, cover one deck EVA casting film to the whole mold outer surface of spring block, spray one deck again by alcohol, glue, the compo that 280 order quartz sands mix, after the vacuo-forming, take out the whole mold of spring block from die joint, form cavity, core is put into and is positioned die cavity, the thickness of EVA casting film is 0.15mm, by alcohol, glue, the thickness of the compo that 280 order quartz sands mix is 0.2 ∽ 0.3mm.
The invention has the beneficial effects as follows: compared with prior art, doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method of the present invention adopts the principle of negative pressure of vacuum, rising head is arranged on the middle boss machined surface, be convenient to exhaust, feeding is even, can improve the density of foundry goods, adopt the EVA casting film of 0.15mm, the integrality of having guaranteed the overlay film die cavity is good, by alcohol, glue, the dope layer that forms after the compo drying that 280 order quartz sands mix can prevent effectively that cast(ing) surface from producing scab phenomenon, make cast(ing) surface fineness good, reduced processing technology, simple to operate, reduced manufacturing cost greatly.
Description of drawings
Fig. 1 is the structural representation of the whole mold of spring block of doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method of the present invention.
The specific embodiment
As shown in Figure 1, doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method of the present invention comprises the whole mold 1 of a spring block, and the whole mold 1 of spring block is divided into the upper and lower mould casting, and its die joint is an A-A direction face.In the endoporus of the whole mold 1 of spring block is disjunctor core 2, and the whole mold boss of spring block is provided with one and begins to crop up 3.
As shown in Figure 1, in actual forming process, at first cover the thick EVA casting film of one deck 0.15mm to whole mold 1 outer surface of spring block, spray the compo that one deck is mixed by alcohol, glue, 280 order quartz sands again, form the dope layer that a kind of thickness is 0.2 ∽ 0.3mm, carry out vacuo-forming then, finish after the vacuo-forming and take out the whole mold 1 of spring block from die joint A-A direction face, form a cavity, die cavity is put into and be positioned to disjunctor core 2.Doube bridge automobile balance suspension plate spring abutment negative pressure of vacuum forming method of the present invention adopts the principle of negative pressure of vacuum, rising head is arranged on the middle boss machined surface, be convenient to exhaust, feeding is even, can improve the density of foundry goods, the EVA casting film that adopts, the integrality of having guaranteed the overlay film die cavity is good, the dope layer that forms after the compo drying that mixes by alcohol, glue, 280 order quartz sands, can prevent effectively that cast(ing) surface from producing scab phenomenon, make cast(ing) surface fineness good, reduce processing technology, simple to operate, reduced manufacturing cost greatly.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
