Description

Rail vehicle fibre glass product manufacture Silicon moulds pipeline jointing construction

Technical field

A kind of composite product forming die structure is the utility model is related to, more particularly, to a kind of rail vehicle glass Product made from steel Silicon moulds pipeline jointing construction.

Background technology

Trolley coach fibre glass product manufacture forms a variety of technology modes, is had at present using more process：Hand is pasted Shaping, RTM shapings, SMC compression moldings, vacuum bag technological forming, Silicon moulds technological forming.Wherein in Silicon moulds forming process most It is the attachment structure into glue point and bleed off passage for key aspect, because being influenceed by the physical characteristic and chemical characteristic of mould silica gel, silicon Intoxicating phenomenon be present with most industrial goods in glue（Do not solidify）, and can not merge with metal material Nian Jie.Therefore, glue is entered Point and the connecting portion structure design of bleed off passage will be relatively difficult, it is difficult to ensure that a complete silica gel bag film have it is one longer Service life.

At present, it is domestic to enter glue point with bleed off passage majority using metal joint using silica gel bag film, use silica type Bonding agent it is Nian Jie with silica gel bag film, then brushing silica gel, and being strengthened with non-woven fabrics, be to connect the advantages of such a structure The standard component of quick connector so that during production, operator is convenient to use.But its shortcoming is also than more prominent：1. because Using the connecting plate of metal structure, metalwork corner and periphery can have corner angle, and this corner angle can produce certain to silica gel mould surface Injury, if rolling and folding during storage Silicon moulds, the time, which has been grown to exist, punctures the risk of silica gel mould surface；2. this The connecting plate and quick connector that kind structure uses, and special silica-gel bonding agent only have the use stabilization of import, but price at present Costliness, delivery cycle length, has considerable influence to the cost and delivery cycle of trolley coach project.

Utility model content

The purpose of this utility model is to provide a kind of Silicon moulds pipe for being adapted to silica gel bag film and entering glue point and pumping port configurations Road attachment structure, the risk for avoiding Silicon moulds storage from causing surface to puncture, while reduce the expensive expense of import partses.

To achieve the above object, the utility model provides a kind of rail vehicle fibre glass product manufacture Silicon moulds pipeline connection knot Structure, including silica gel bag film back of the body mould, glue inlet tube, it is characterised in that：Silica gel connector is integrally formed above silica gel bag film back of the body mould, enters glue In the cylindrical hole of pipe insertion silica gel connector, silica gel connector outer surface is clamped by hose clamp.

The utility model is simple and convenient during silica gel bag film use, can will directly enter the pipeline of glue or pumping Be inserted directly into prefabricated silica gel cylindrical cavity, using the hose clamp purchased on the market clamp can to reach the requirement of sealing, Cost substantially reduces.And roll and fold all without the risk for causing to puncture silica gel mould surface, this practicality during storage Silicon moulds New with silica gel bag film be same material, has evaded the phenomenon of silica gel poisoning, and it is more preferable to be bonded fusion degree, more durable, can be with With the silica gel bag film same life-span.

Brief description of the drawings

Fig. 2 is the utility model silica gel bag membrane tube road connection diagram；

Fig. 3 is the forming die structure figure of the prefabricated connector of the utility model.

Embodiment

Referring to Fig. 1, the current domestic glue inlet tube 1 for using silica gel bag film（Or exhaust tube）It is most using metal joint 3, It is be bonded with silica gel bag film notacoria 4 using the bonding agent of silica type, then brushing silica gel, and strengthened with non-woven fabrics, such a structure The advantages of be that can connect standard component quick connector 2 so that during production, operator is convenient to use.But because of metalwork Corner and periphery can have corner angle, and this corner angle can produce certain injury to silica gel mould surface, if rolled during storage Silicon moulds And folding, the time, which has been grown, will have the risk for puncturing silica gel mould surface.

Referring to Fig. 2, silica gel bag film back of the body mould 4 is integrally formed silica gel connector 5 above, and glue inlet tube 1 inserts silica gel connector 5 In cylindrical hole, the outer surface of silica gel connector upper orifice is clamped by hose clamp 6.In production, silica gel bag film notacoria is completed Afterwards, the glue inlet tube of process stipulation is inserted in the cylindrical hole of prefabricated connector, clamps hose clamp, can be to use.Because of prefabricated company The material of fitting 5 is silica gel, and no corner angle will not produce damage to silica gel mould surface, is easy to roll and fold when depositing Silicon moulds, This prefabricated connector instead of the metal connecting piece and special gelatin of import simultaneously, greatly reduces material cost, simplifies work Skill process.

Referring to Fig. 3, nonstandard assembling die 7,8, using silica gel spraying equipment, the silica gel that will be mixed are made with Q235 materials Be expressed among mould, silica gel less than when, cut 100 × 100MM sizes technology strengthen cloth（Cut circular hole in centre）, fill in mould Have in forming cavity, continue to irrigate silica gel, until the full mold cavity of silica gel perfusion；Solidification can be stripped after 24 hours, prefabricated connector 5 Just it is made.

Claims (1)

1. a kind of rail vehicle fibre glass product manufacture Silicon moulds pipeline jointing construction, including silica gel bag film back of the body mould, glue inlet tube, its feature It is：Silica gel connector is integrally formed above silica gel bag film back of the body mould, glue inlet tube is inserted in the cylindrical hole of silica gel connector, and silica gel connects Fitting outer surface is clamped by hose clamp.
