A kind of casting technique of PU triplets cushion mold

Technical field

The present invention relates to PU die castings field more particularly to a kind of casting techniques of PU triplets cushion mold.

Background technology

Consumption with market after Chinese automobile articles for use is persistently increased, and automobile seat cushion also becomes the main of car owners The consumer goods.It is particularly important according to a set of comfortable, the practical automobile seat cushion of Season select.PU automobile cushions have comfortable, soft Toughness, durability and not rapid wear, shape-designing is free, eliminates pressure spot, promotes blood in human body in no instance It can be oppressed.

Polyurethane material is the current best thermal insulation material of performance in the world.Main chain is containing-NHCOO-constitutional repeating unit A kind of polymer, english abbreviation PU.It is polymerized with hydroxy compounds by isocyanates (monomer).Due to containing highly polar ammonia Carbamate base does not dissolve in non-polar group, has good oil resistivity, toughness, wearability, resistance to ag(e)ing and adhesiveness.With The material for adapting to wide temperature range (- 50~150 DEG C), including elastomer, thermoplastic resin and thermosetting can be made in different material Property resin.Not hydrolysis under high temperature, also not alkali-proof medium.

Polyurethane foam plastics application range is very extensive, almost penetrates into each department of national economy, especially in furniture, bed The departments such as tool, transport, refrigeration, building, thermal insulation use very universal, it has also become one of indispensable material.As plastics Most wide one of the kind of middle application range.Soft polyurethane foam is mainly used in furniture, bed accessory and other household wares, such as sofa and seat Chair, backing cushion, mattress and pillow;Hard polyurethane foam is mainly used for adiabatic heat-insulation, refrigerating equipment and freezer, heat-insulating plate, Wall thermal insulating, pipe insulation, the thermal insulation of storage tank, monocomponent bubble pointing etc..

The global density template die using three pieces mode is needed in the casting technique of PU triplets cushion mold in the prior art The rapidoprint of type, density Slab is more, long processing time, and production cost is high.Accordingly, it is desirable to provide one kind can reduce production The casting technique of the PU triplet cushion molds of cost.

Invention content

In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a kind of PU triplets that can reduce production cost The casting technique of cushion mold.

In order to solve the technical problem in background technology, the present invention provides a kind of founders of PU triplets cushion mold Skill includes the following steps:

S1, a density Slab progress founding is obtained into three resin bonded sand moulds;

S2, by three resin bonded sand moulds, assembly forms resin bonded sand mould A side by side;

S3, a polyurethane models founding is obtained into polyurethane resin sand mold B;

S4, the resin bonded sand mould A and polyurethane resin sand mold B or more is fastened, forms resin bonded sand mould C;

S5, the aluminium that molten condition is poured into a mould in the cavity of resin bonded sand mould C, PU triplet cushion molds are obtained after cooling.

Preferably, the density Slab in the step S1 is single density board.

Preferably, the bottom edge of three resin bonded sand moulds is set on same straight line in the step S2.

Preferably, polyurethane models are assembled side by side by three modes in the step S3.

Preferably, the bottom edge of three modes is set on same straight line.

Preferably, the shape of the mode, size all same.

Preferably, the both ends polyurethane resin sand mold B have side wall.

Preferably, in the step S4, the polyurethane resin sand mold B back-offs are above the resin bonded sand mould A.

Preferably, in the step S4, the polyurethane resin sand mold B coat the top of the resin bonded sand mould A, left part and Right part.

Preferably, the resin bonded sand mould C is the hollow structure that surrounding is closed.

The beneficial effects of the invention are as follows:

(1) casting technique of PU triplet cushion molds of the invention, by the global density Slab of original three pieces mode Make single density Slab into, then founding obtains three pieces resin bonded sand mould, has saved material and the process time of density board, together When reduce the labor intensity of worker;

(2) casting technique of PU triplet cushion molds of the invention, prepares the polyurethane resin sand mold with side wall, Ensure the side wall of one circle when two panels resin bonded sand mould is closed instead of original sandbox;

(3) casting technique of PU triplet cushion molds of the invention, eliminates sandbox equipment, simplifies production technology, Production cost is saved.
