Description
Technical field：
The invention belongs to the technical field that composite is manufactured, and in particular to a kind of electric heating is from heating mould and utilizes its progress
Glass fibre ties up the forming method of reinforced plastics.
Background technology：
Since 21 century, global composite markets rapid growth, composite industry auto industry, railway projects,
Big Aircraft Project etc. achieves increasingly consequence, composite material parts manufacturing industry it is also proposed inexpensive, short
Cycle etc. requires and challenge.In the prior art, the temperature control intelligent of large-scale composite material mould product comes by large-scale curing oven
Complete, production equipment demand and energy resource consumption have a drawback, and application scenarios are dumb.
Can be inconsistent due to non-uniform temperature, the cooling rate of the mould of self-heating in manufacturing process additionally, due to some composites
Defect is caused to product etc. reason, such as the defects of variable thickness causes, material surface ftractures or inside is full of minute fissure, influenceed
The quality of product.
The content of the invention：
To solve the problems, such as that prior art is present, the present invention proposes that a kind of temperature-controllable is high, will can be molded and elevated cure is whole
Close to the electric heating that a step is completed from the mould that heats up, adopt the following technical scheme that：
A kind of electric heating is provided with soft electrical heating pipeline from heating up mould, including die matrix and controller in die matrix,
Semiconductor chilling plate is provided with the die matrix below soft electrical heating pipeline, TEMP is additionally provided with die matrix
Device, soft electrical heating pipeline, semiconductor chilling plate and the temperature sensor are connected to controller.
The soft electrical heating pipeline is set in a ring in the horizontal direction with semiconductor chilling plate, wherein soft electrical heating pipeline is set
Put and be arranged on inner ring in outer shroud, semiconductor chilling plate.
The controller is connected with soft electrical heating pipeline, semiconductor chilling plate and temperature sensor by quick plug.
A kind of forming method of fiberglass reinforced plastics, is characterized in, glass fibre is carried out from the mould that heats up using foregoing electric heating
The shaping of reinforced plastics, and comprise the following steps：
Step 1：The paving glass fibre raw material on die matrix；
Step 2：By soft electrical heating pipeline be die matrix heat, and by temperature maintain 130~150 DEG C between keep 3~5
Hour；
Step 3：Reduce the supply current of soft electrical heating pipeline with 5~8%/min speed, while with 3~4%/min speed
Rate increases the refrigeration work consumption of semiconductor chilling plate, until the fiberglass reinforced plastics temperature in die matrix and die matrix reduces
To 30 DEG C；
Step 4：The fiberglass reinforced plastics after shaping is removed out of die matrix.
Beneficial effects of the present invention：The present invention's can improve Forming Quality of the composite in forming process from heating mould,
Due to having used semiconductor chilling plate, common mould is better than to the temperature control capability of die matrix, controls uniform cooling speed
Rate, improve surface thickness uniformity.
Brief description of the drawings：
Fig. 1 is the structural representation of one embodiment of the present of invention；
Fig. 2 is the top view of Fig. 1 die matrix；
Wherein：1- controllers, 2- quick plugs, 3- temperature sensors, the soft electrical heating pipelines of 4-, 5- die matrix, 6- are partly led
Body cooling piece.
Embodiment：
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the present invention, as shown in Fig. 1~Fig. 2, of the invention reality
Example is applied, a kind of electric heating is provided with soft electricity in die matrix 5 and added from heat up mould, including die matrix 5 and controller 1
Hot pipeline 4, semiconductor chilling plate 6 is provided with the die matrix 5 below soft electrical heating pipeline 4, in die matrix 5
Temperature sensor 3 is additionally provided with, soft electrical heating pipeline 4, semiconductor chilling plate 6 and the temperature sensor 3 are connected to control
Device 1 processed.The soft electrical heating pipeline 4 is set in a ring in the horizontal direction with semiconductor chilling plate 6, wherein soft electricity adds
Hot pipeline 4 is arranged on outer shroud, and semiconductor chilling plate 6 is arranged on inner ring.
The controller 1 passes through quick plug 2 with soft electrical heating pipeline 4, semiconductor chilling plate 6 and temperature sensor 3
It is connected.By quick plug 2 controller can be made to control multigroup die matrix 5 and its internal unit, spirit can be realized
Production management living.
Due to fiberglass reinforced plastics, generally outside cooling velocity is fast in forming process, and internal cooling speed is slow, therefore easily goes out
The now fault in material because caused by cooling velocity is inconsistent.It can be effectively reduced and be molded from the mould that heats up by the electric heating of the present invention
Fault in material in journey, specifically, using following steps：
Step 1：The paving fiberglass reinforced plastics into die matrix 5；
Step 2：By soft electrical heating pipeline 4 be die matrix 5 heat, and by temperature maintain 130~150 DEG C between protect
Hold 3~5 hours；
Step 3：Reduce the supply current of soft electrical heating pipeline 4 with 5~8%/min speed, while with 3~4%/min's
Speed increases the refrigeration work consumption of semiconductor chilling plate 6, until the fiberglass reinforced plastics in die matrix 5 and die matrix 5
Temperature is below 30 DEG C；
Step 4：The fiberglass reinforced plastics after shaping is removed out of die matrix 5.
