Above-mentioned die body inner core is a vinyl composite, and its outer surface is by mould gel coat and vinylite and glass cloth hand pasting forming.Above-mentioned loose piece inner core is an epoxy resin-base composite material, and its outer surface is by epoxy gel coat and epoxy resin and glass cloth hand pasting forming.
The utility model is owing to adopted technique scheme, its beneficial effect is as follows: 1. mould of the present utility model is used for moulding truck engine covering with the vacuum-assisted resin transfer moulding technology, realized the one-shot forming technique of large component, having changed for a long time, large component can only use the final manufacture method that forms of welding of a plurality of moulds, reduce labour intensity, improved operating efficiency.2. in order to solve the protruding difficulty that causes when the moulding caused matched moulds or the demoulding of the side of large component own; the utility model is provided with loose piece on the position of the demoulding; and bear down on one with the liquid parting of the corresponding setting of this loose piece, solved an above-mentioned difficult problem effectively, improved the demoulding efficiency of this product.3. vacuum port is between the double density strip of paper used for sealing, and sealing strip is flush-mounted in the former upper surface along peripheral direction or the vacuum port both sides offered at formpiston, promptly can guarantee the vacuum in the die cavity, also can effectively prevent overflowing of resin, has reduced the pollution to environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is beared down on one by former 1, formpiston 2, loose piece 3, sealing strip 41,42, former locating slot 5, formpiston reference column 6, gum-injecting port 7, vacuum hole 81,82,83, die cavity 9, liquid parting and 10 forms with heating tube 11.Wherein, former 1 and formpiston 2 are formed the die body of these moulds, and the inner core of die body is a vinyl composite, and its outer surface is by mould gel coat and vinylite and glass cloth hand pasting forming; Formpiston reference column 6 is positioned at the lower surface edges at two ends place of formpiston 2, former locating slot 5 is positioned at the upper surface edges at two ends place of former 1 and corresponding to the formpiston reference column 6 on the formpiston 2, when former 1 and formpiston 2 matched moulds, formpiston reference column 6 is combined closely with former locating slot 5, finishes the accurate location of former 1 and formpiston 2.
One end of former 1 is a convex, and die cavity 9 is positioned at the inner side edge of former 1 projection and the upper surface of former 1, liquid parting is installed on the side of projection bears down on one 10; One end of formpiston 2 is a recess-like, and its recessed inner side edge coincide mutually by loose piece 3 with the die cavity 9 of former 1 lug boss and is connected; The shape of the dual-side of loose piece 3 shape with the recessed inner side edge of die cavity 9 sides and formpiston 2 respectively is identical;
Gum-injecting port 7 vertically is opened on the die joint of formpiston 2, and the position of gum-injecting port 7 can specifically be determined with die cavity 9 and resin flows situation; Be provided with 3 vacuum holes 81,82,83 in the present embodiment in formpiston 2, vacuum hole 82 is positioned at the recessed inner side edge of this formpiston 2 and corresponding to the position of loose piece 3, is embedded with bar shaped sealing strip 41 respectively in vacuum hole 82 both sides; The vertical logical respectively both sides of being located at formpiston 2 of vacuum hole 81,83, the upper surface of former 1 along whole circumferential setting-in spacing be the paired annular seal bar 42 of 40mm, the lower end of vacuum hole 81,83 and the contact-making surface of die joint drop between the annular seal bar 42; By the vavuum pump of peripheral hardware by vacuum hole 81,82,83 with mold cavity 9 shape that is evacuated, vavuum pump stops to find time when the vacuum meter scale reaches-0.095. Sealing strip 41,42 can realize that the vacuums in the die cavity 9 remain unchanged, and under vacuum action, work fast 3 is combined closely with former 1 and formpiston 2, alleviates loose piece 3 pressure to preform under the deadweight effect simultaneously, thereby helps resin flow; In addition, sealing strip 41,42 can prevent overflowing of resin, reduces the pollution to environment.After vavuum pump stopped to find time, resin was injected in the die cavity 9 by gum-injecting port 7.
Heating tube can have dual mode, and a kind of mode is: heating tube is set to 1, and it is shaped as helical form, is positioned at 10～15mm place under the die cavity; The second way is: heating tube is set to some, installs and evenly distributes perpendicular to die cavity, heating tube 10～15mm place under the die cavity.Heating tube 11 is a copper pipe, and diameter is 10mm, and flowing in the pipe, recirculated water, its recirculated water are arranged is that water temperature is 50 ℃ a hot water.After the resin injection finished, heating tube 11 fed hot water, and the truck engine covering product by heating that die cavity 9 forms is solidified.Separate former 1 and formpiston 2 afterwards, utilize liquid parting to bear down on one and 10 this product ejected with loose piece 3, then loose piece 3 is taken off, so just finished the production of engine covering.
The foregoing description is an optimal way of the present utility model.Obviously, this area professional is according to the vacuum requirement, and vacuum hole also can be provided with several more, is positioned at the recessed inner side edge of this formpiston 2 and also can be provided with a plurality of corresponding to the vacuum hole of the position of loose piece 3.
