Description
Technical field
The utility model is related to a kind of experiment mould, and more particularly to a kind of experiment for resin transfer molding is filled
Put.
Background technology
The engine room cover product of manufacture wind-driven generator can use resin transfer molding technique (Resin Transfer
Moulding, abbreviation RTM), RTM is a kind of closed molding processes, is to inject resin into infiltrate reinforcing material in Guan Bi mould
And the process solidified.This technology can be effectively reduced equipment cost, shaping cost, the work without prepreg, autoclave
The product surface of skill production is smooth, and product is attractive in appearance, is relatively advanced production technology in fibre glass product manufacture industry.
But it is due to that RTM techniques are that above mould and lower mould are the moulding process of core, therefore can not be observed during technological operation
The flowing of resin and Infiltrating, the defect for product are not easily controlled.RTM shaping in, if having process change or some
New material substitutes, and the result for product is more difficult to control, once huge loss will be caused by deviation occur.
, can be to process change or new material more accordingly, it would be desirable to a kind of experimental provision for resin transfer molding
RTM techniques after replacing carry out experimental simulation, formed product mistake of the product result situation made by experiment mould to large-scale RTM
Journey is estimated, so that the generation of defect is reduced or avoided, reduces cost.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of experimental provision for resin transfer molding,
RTM techniques after can substituting process change or new material carry out experimental simulation, the product result made by experiment mould
Situation is estimated to large-scale RTM formed product process, so that the generation of defect is reduced or avoided, reduces cost.
Experimental provision of the present utility model for resin transfer molding, including upper die and lower die, the upper mould and
Form the die cavity area for injection molding between lower mould, in addition to for determine die cavity area pressure pressure sensor and for pair
The vacuum pumping hole that die cavity area is vacuumized.
Further, the first poly tetrafluoroethylene of ventilative resin-proof, the upper mould and the first polytetrafluoroethylene (PTFE) are included
The space of the sensing element for accommodating the pressure sensor is formed between film.
Further, the vacuum pumping hole passes through the upper mould, is pasted in vacuum pumping hole close to the one end in the die cavity area
Upper mould is provided with the second poly tetrafluoroethylene.
Further, it is provided with cover plate to be opened/closed on the vacuum pumping hole.
Further, it is provided with caulking gum between the cover plate and the vacuum pumping hole.
Further, the junction of the upper die and lower die is provided with caulking gum.
The beneficial effects of the utility model：Experimental provision of the present utility model for resin transfer molding, can be with
RTM techniques after substituting process change or new material carry out experimental simulation, the product result situation made by experiment mould
Formed product process to large-scale RTM is estimated, so that the generation of defect is reduced or avoided, reduces cost.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
