There is hole for injecting glue 1111 and gas vent 1112, for being poured when being made to Silicon moulds 30 in first shell 111
Gas in note and discharge casting mold 10.
In the present embodiment, core model 13 includes that mould portion 131 and plastotype portion 132, plastotype portion 132 is divided to be embedded at a point mould portion
131.Plastotype portion 132 is primarily used to form the inner cavity surface of Silicon moulds 30 so that inner cavity surface can be with composite material to be prepared mother
The outer profile of connector 200 is adapted to.Divide mould portion 131 to be used for after Silicon moulds 30 pour into a mould curing molding, Silicon moulds 30 are separated into
Multiple pieces of moulds 31, the present embodiment are three block moulds 31, therefore mould portion 131 is divided to be also to be arranged in correspondence with into three parts.
The Silicon moulds 30 of the present embodiment, the geomery of formpiston 50 are mainly as shown in Figure 10 to be answered according to what is manufactured
Condensation material female connector 200 and formulate, based on parameter index mainly have the wall thickness, internal diameter and length of connector, also connector
Mutual angle.If manufacturing other shapes feature connector similar with the composite material female connector 200 of the present embodiment, also may be used
Change corresponding construction feature so that the present embodiment is reference, to meet manufacture needs.
The principle of the present embodiment is:
Formpiston 50 and casting mold 10 are gone out according to the size design of product first, following operation is then pressed and carries out product system
It makes.
Liquid silica gel is injected to filling at hole for injecting glue 1111 after housing mould 11 is installed in place with core model 13, and cooling is fixed
It is demoulded after type, obtains Silicon moulds 30;
By the carbon fiber/epoxy resin base prepreg cut on formpiston 50 laying, until product thickness;
Silicon moulds 30 are sleeved on to the outside of prepreg, molding space is occupied by prepreg at this time;
Housing mould 11 is set in the outside of Silicon moulds 30, multiple pieces of moulds 31 are locked;
It is sent into baking oven, according to the curing cycle of 80 DEG C/1.0h+120 DEG C/2h, curing molding;
It is cooling;
Demoulding opens housing mould 11, and removes Silicon moulds 30.The second knock-outs 522 are screwed out using allen wrench,
So that the demoulding of the second molded part 502, then screws stripper bolt 5212 with die nut, sleeve is pushed by demoulding nut 5213
5211, sleeve 5211 pushes composite material female connector 200 so that composite material female connector 200 demoulds completely.
Wherein, prepreg can also be aramid fiber/cyanic acid other than using carbon fiber/epoxy resin base prepreg
Ester resin base prepreg or other types prepreg, to meet the making of different types of female connector.Solidification temperature is not with
With the difference of prepreg model and it is different, 80 DEG C/1.0h+120 DEG C of general glass fibre prepreg and carbon fiber prepreg/
2h, also part carbon fiber prepreg and aramid fiber prepreg are 80 DEG C/1.0h+150 DEG C/1.0h+180 DEG C/3h etc..
The prepreg of composite material female connector 200 is made in by curing process, silica gel expanded by heating gives solidification process
In prepreg press certain pressure, the coefficient of thermal expansion of silica gel is higher, therefore, can apply to prepreg in thermal histories
The pressing force of 0.3MPa-1.0MPa, interior porosity greatly reduces after higher pressing force makes prepreg cure, therefore, system
The good mechanical performance of the composite material female connector 200 obtained.
The critical size of composite material female connector 200 is internal diameter size, and internal diameter size is the formpiston made by metal
50 come what is controlled, and the precision of intermetallic composite coating can reach within 0.01mm, therefore, the internal diameter size of composite material female connector 200
± 0.01mm can be reached, dimensional accuracy is high.
Embodiment 2
Figure 11 is please referred to, the present embodiment also provides a kind of composite material female connector molding die, for manufacturing Figure 11 institutes
The composite material female connector 200a shown.
The present embodiment and the main distinction of embodiment 1 are:
The quantity of second molded part 502 and the second knock-outs 522 is two.
By two the second molded part 502 numbers at No. 1 part, No. 2 parts, the first molded part 501 is numbered into No. 3 parts, No. 1 part
With No. 2 parts symmetrically and at 60 ° of angles, No. 1 part and No. 3 parts are at 60 ° of angles.
In addition, such as other structures of the structure of core model 13, the structure of Silicon moulds 30, formpiston 50, are all correspondingly become
Change, to be adapted to the manufacture requirement of the composite material female connector 200a of the present embodiment.
Other structures can refer to embodiment 1.
The operation when manufacture of the composite material female connector 200a of the present embodiment is referred to embodiment 1, embodiment 1 and reality
The design basis for applying example 2 communicates.The prepreg that the present embodiment uses is aramid fiber/cyanate resin base prepreg, prepreg
Selection equally can also be the prepreg of other type, can refer to embodiment 1.
In conclusion the composite material female connector molding die binding silica gel coefficient of thermal expansion height and metal of the utility model
Die size advantage with high accuracy can make high dimensional accuracy and high performance composite material female connector.In addition, passing through this reality
With novel design concept, the difficulty of operation can be reduced, mould structure is simple and reliable.For different connector quantity and connect
Head angle different female connector each other, can also the corresponding casting mold 10 of respective production, Silicon moulds 30 and formpiston 50, base
This thinking and inconvenient, is conducive to make different types of female connector, extremely have use value.
