Description
Technical field
It the utility model is related to the anti-striker ejection technique field of automobile using, more particularly to a kind of EA mold glues moulding/demoulding
Device.
Background technology
Hard polyurethane foam be using isocyanates and polyethers as primary raw material, it is more in foaming agent, catalyst, fire retardant etc.
In the presence of kind auxiliary agent, mixed by special equipment, the high molecular polymer formed through high pressure painting foam-in-place.Polyurethane foam
There are soft two kinds of bubble and hard bubble.Soft bubble is open-celled structure, and hard bubble is hole-closing structure.The major function of soft polyurethane foam is buffering.It is poly-
Urethane hard bubble body is a kind of novel synthetic material with insulation and water-proof function, and its thermal conductivity factor is low, equivalent to extruded sheet
Half, it is that thermal conductivity factor is minimum in current all insulation materials.RPUF is mainly used in outside building
Wall is incubated, and waterproofing and thermal insulation of roofing is integrated, heat preservation of refrigeration storage is heat-insulated, pipe insulation material, building board, refrigerator car and freezer are heat-insulated
Material etc..
At present, the domestic formula and production technology for having grasped polyurethane foam glue completely, generally use and do not destroy ozone
The floride-free foaming agent of layer, and have developed the polyurethane foam glue of preceding foaming.Except part producer still uses imported valve accessory
Outside, other supporting raw material have domesticized.Use result for many years shows that preceding polyurathamc foamed glue has preceding foaming, receipts
The good characteristics such as diminution, highly expanded, elasticity is good, in Shanghai World Expo Japan shop, New Zealand shop, Olympic Village, construction of Guangzhou Asian Games stadiums village
Good effect is achieved in use etc. engineering.
In polyurethane moulded processing, releasing agent is used to obtain the product of any surface finish.Polyurethane and other materials
With excellent adhesive property.This property is unfavorable in foams molding.In molded polyurethane foam, cast polyurethane
In the production of product such as elastomer and the reaction injection molding that quickly grows in the world.In order to successfully be removed from the molds rapidly
Product, releasing agent must be used at present.Ideal releasing agent should have preferable heat endurance and chemical stability, be stale-proof
Mould is lost, in the not remaining analyte of die surface；Should be able to give product good outward appearance, do not influence the color and luster of product, cohesive,
By paint ability etc.；The mold cleaning time as few as possible should be required；Should be nontoxic, safety is easy to operation.Answer cost relatively low.Poly- ammonia
The cohesive force of ester and die surface is generally acknowledged that caused by both sides reason.First, the surface of mould would generally be by one layer very
The moisture film of thin even monolayer is covered, this layer of very thin moisture film and the cohesive that strength is produced after isocyanates reaction；
Secondly, bonding is reacted and caused chemical bond by the polar group of the polar group and polyurethane and poly- arteries and veins of mould endosexine
It is caused.
In reality production at present, the production of EA products in mould using releasing agent is sprayed, from mould after shaping to be foamed
EA products are taken out in tool.Because by releasing agent batch or model, and personnel, equipment each side condition limitation, operation
Personnel's product in stripping operation is not easy to take out, and adds operation intensity, influences operating efficiency, it is also possible to can cause product not
Situation that is good and scrapping.Meanwhile waste gas caused by spraying releasing agent also result in operating environment pollution, have a strong impact on operating personnel
Health.
