The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
This specific embodiment mainly comprises upper die component, last knock-outs will, upward heating member, lower cavity die, bottom knockout part, following heating member, heat preservation member and temperature control system are formed.
As shown in Figure 1, upper die component comprises cope match-plate pattern 1, goes up punch 2 and guide 13, is used for fixing shape in mould and the moulded products, and guide 13 is used to guarantee that punch 2, lower cavity die 6 are coaxial, controls the products thickness dimensional discrepancy; Last knock-outs will 4 is used to take off the goods that are bonded on the punch, also can increase heating tube on knock-outs will, and glass fiber reinforced plastics product is assisted heating; Last heating member 5 is used for goods top and inside are heated in the epirelief die cavity; Lower cavity die 6 is used for fixing mould and moulded products profile; Form product molding space 12 between last punch 2 and the lower cavity die 6.
Bottom knockout part 7 is used to take off the goods that are bonded in the lower cavity die 6, smooth no step is answered in transition between bottom knockout part 7 and the lower cavity die 6, bottom knockout part 7 has the ventilation effect, and 6 of outer surface and lower cavity dies form vacuum when avoiding the pressed glass steel part, influence the quality of item and the demoulding; Following heating member 8 mainly heats lower cavity die 6 parts, is main heater block; Be to solve being heated evenly property of cone barrel part upper and lower surface, adopted in cope match-plate pattern 1, the lower bolster 10 inner heating tube modes that increase, heating tube can annular or layout radially in the template; Heat-insulation layer 9 is arranged on cope match-plate pattern 1, lower bolster 10 and following heating member 8 outer surfaces for improving the thermal efficiency; The temperature sensor 11 of temperature control system is distributed in and gathers the temperature of heating in the upper die component, lower cavity die 6 in real time, and temperature control system reaches and regulates the mould heating rate by the upper and lower heating member of grouping control, and control mold temperature value scope be no more than ± 5 °.
Certain cone barrel article construction is seen Fig. 2, and for high silica fiber strengthens the phenoplasts compression molding, this product size is bigger, wall is thin, the even transmission of heat when this shape very is unfavorable for heating, and it is a penetrant structure, the material flow difficulties is unfavorable for direct compression molding.
Go up defective for overcoming Fig. 2 taper article construction compression molding processing, the dome structure of the awl tube end face of Zhou Peihe for being communicated with in punch 2 peripheries and the lower cavity die 6 in Fig. 1, thereby the flowability of prepreg when improving mold pressing, goods after its direct compression molding as shown in Figure 3, that is, at the goods small end circular arc bottom surface is arranged, large end face has more the high surplus of 1mm～2mm than the design goods, remove big small end face with the machining mode then, just obtain the cone barrel goods that adhere to specification.
The mould primary structure is pressed structure shown in this patent fully, comprise upper die component 1, go up knock-outs will 2, go up heating member 3, membrane module 4, bottom knockout part 5, heating member 6, auxiliary heating member 7, heat preservation member 8 and temperature control system 9 down down, by control that heating member is divided into groups, guarantee mold temperature value scope be no more than ± 5 °, guarantee that mold pressing goes out qualified part.
This mould structure belongs to the vertical-parting structure, can guarantee that briquetting pressure puts on the part effectively, thereby makes goods obtain the excellent surface quality, and has enough gaps that air is overflowed again; The mold flashing gap is selected rationally, and big goods then should increase in the flash gap, and the flash gap is too small, air is overflowed difficult, and excessive then can the growth encourage flowing of this direction causes the fiber orientation, produces ripple, weaken product strength, the gap of its flash gap and vertical-parting structure is within same scope; The size in reinforced chamber is calculated according to extrudate density and reinforced number of times and is determined, should be principle to reduce reinforced number of times as far as possible, in order to avoid increase the layers of material probability; For guaranteeing the goods precision, punch and die need be considered amount of contraction, and the product diameter has tendencies toward shrinkage behind the type mould molding, and elongation trend is highly arranged.Adopt said structure to solve the key technology of cone barrel composite material parts moulding, can realize the product one-shot forming, effectively guaranteed product quality.
In addition; above-mentioned embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can carry out the change of some unsubstantialities to it; so long as do not exceed the spiritual essence of this patent; all be considered as the replacement that is equal to, therefore all within the protection domain of this patent to this patent.
