Abstract
A kind of subway ceiling mould structure, including square unitary mould body, product stepped locations one loose piece of connection is corresponded on the inside of die ontology riser, loose piece is stripped together in company with product when product opens mould, it ensure that whole mould is air tight, and can ensures that product is smoothly stripped.By the improvement of the utility model mould structure, it both can guarantee that product was air tight in forming process, and reduced the scrappage of product, moreover it is possible to reduced the molding time of product（Mould is carried out to fill out atomized ash before shaping, and carries out the processes such as pasted with high temperature-resistant indigo plant film of polishing）, production efficiency is drastically increased, saves time cost, shortens the formed product cycle, reference and sample are provided for follow-up Mold Making.
Description
Technical field
The utility model belongs to rail vehicle subway ceiling mould structure, is answered more particularly, to one kind suitable for profile
The anti-gas-leak unitary mould for the product that miscellaneous, unitary mould can not be stripped.
Background technology
In recent years, as the development of China railways cause, various new vehicles continue to bring out, increasing material is wide
General to apply in rolling stock, wherein composite has obtained increasing popularization, as outstanding in composite
Person --- prepreg, the arrangement of resin content, reinforcing material content and reinforcing material, resin are accurately controlled in forming process
Outflow is few, can obtain mechanical property and the very high product of appearance and size precision, complete, internal gas is impregnated additionally, due to prepreg
Bubble is few, product surface excellent effect, and quality level is high, has obtained good application in the composite.Prepreg passes through vacuum
Pressure bag method high-temperature molding, there are strict requirements to the sealing of mould, once product gas leakage may result in forming process
Whole product rejection.For complex contour, product that unitary mould can not be stripped, its mould is made up of two Split molds, and two
The surface of split and across groove is provided with die joint, before production, fills up in groove and tamps atomized ash, handling polishing makes
Surfacing it is smooth, and at atomized ash and die surface pasted with high temperature-resistant sealing indigo plant film, but during due to the formed product
Hot setting is needed, expansion occurs when atomized ash is by high temperature, crack locally occurs, often occurs that seam crossing gas leakage etc. is existing
As, once the whole product of gas leakage will be scrapped.
Utility model content
The purpose of this utility model is to provide a kind of adaptation complex contour, the subway ceiling production of easy mold release is used
, it is necessary to divide installation mold loose piece at mould, companion product carries out opening mould together unitary mould, ensures that mold body is air tight.
To achieve the above object, the utility model provides a kind of subway ceiling mould structure, including square entirety mould
Have body, product stepped locations are corresponded on the inside of die ontology riser and connect a loose piece, loose piece is in company with production when product opens mould
Product are stripped together, that is, ensure that whole mould is air tight, and and can ensures that product is smoothly stripped.
Described activity is by screw with being connected on the inside of die ontology riser.
By the improvement of the utility model mould structure, it both can guarantee that product was air tight in forming process, and reduced production
The scrappage of product, moreover it is possible to reduce the molding time of product（Mould is carried out to fill out atomized ash before shaping, and carries out polishing and pastes resistance to height
The processes such as the blue film of temperature）, production efficiency is drastically increased, saves time cost, shortens the formed product cycle, is follow-up mould
Tool making provides reference and sample.
Brief description of the drawings
Fig. 1 is using the die cut view for dividing modular form；
Fig. 2 divides the mould partial enlarged drawing of modular form；
The sectional view of Fig. 3 the utility model moulds；
The partial enlarged drawing of Fig. 4 the utility model moulds.
Embodiment
Reference picture 1, Fig. 2, flat-top panel products 1 are the thick prepregs of 8mm and paper honeycomb composite molding, during the formed product,
Using vacuum flexible bag moulding technique, vacuum bag mould is pasted onto at die flanging and vacuumized so that between the bag film of mould
Negative pressure is formed, compacting prepreg ensures compact dimensions.
Mould is made up of two Split molds 2 and 3, is provided with groove at the surface of two splits and leap die joint, is passed through spiral shell
Bolt 4 and nut 5 are attached, and before production, are filled up in groove and are tamped atomized ash 6, and processing polishing is allowed to surfacing light
It is sliding, and at atomized ash and die surface pasted with high temperature-resistant sealing indigo plant film, but due to needing hot setting during the formed product,
Expansion occurs when atomized ash is by high temperature, crack locally occurs, phenomena such as seam crossing gas leakage often occurs, once gas leakage is whole
Individual product will be scrapped.
Reference picture 3, Fig. 4, mould 7 are integrated mould, and 8 be mould part, and 9 be screw, and mould 7 is made of one, product and
Mold releasability is easy, and mould part 8 is fixed on integration mold 7 by product before operation, using screw 9, after formed product
Screw 9 in mould part 8 is backed out, mould part 8 is taken off together with product from integration mold 7, has reached easily de-
The purpose of mould.
By the improvement of the utility model mould structure, it both can guarantee that product was air tight in forming process, and reduced production
The scrappage of product, moreover it is possible to really reduce the molding time of product（Mould is carried out to fill out atomized ash before shaping, and it is resistance to carry out polishing stickup
The processes such as high temperature indigo plant film）, production efficiency is drastically increased, saves time cost, shortens the formed product cycle, is follow-up
Mold Making provides reference and sample.
