The specific embodiment:
Below in conjunction with accompanying drawing, specific embodiment of the invention scheme is elaborated:
With reference to accompanying drawing, a kind of breaker case injection moulding curing molding mould based on thermosets of the present invention, by cover half pull 3, cover half fixed head 4, cover half cavity plate 6, movable model central layer 8, mould pin 10, moving clamping plate 11, demoulding supporting plate 15, demoulding fixed head 16, guide pillar 20, guide pin bushing 21, cover half inserts 24, automatism isolation cutoff device and stripper apparatus form, at cover half, pull on 3, be provided with pressure injection-moulded runner 1, between cover half fixed head 4 and cover half cavity plate 6, be equipped with cover half thermal insulation board 5; Between movable model central layer 8 and mould pin 10, be equipped with dynamic model thermal insulation board 9.The heat that cover half thermal insulation board 5 can effectively intercept cover half cavity plate 6 conducts to cover half fixed head 4; Dynamic model thermal insulation board 9 can effectively prevent the forfeiture of heat on movable model central layer 8.To guarantee the needed heat cured temperature parameter of thermosets.
On cover half fixed head 4, be provided with cover half cooling water runner 2; Cover half cooling water runner 2 communicates with the cooling water runner on cover half inserts 24, form chilled(cooling) water return (CWR), make cover half fixed head 4 and cover half inserts 24 all the time in normal temperature state, to guarantee under the certain pressure of normal temperature, thermosets in injection molding channel 1 has good mobility, guarantees that thermosets is not heated in normal temperature occur to solidify.
On cover half cavity plate 6 and movable model central layer 8, be respectively arranged with cover half bottoming hole 7 and dynamic model bottoming hole 22.In injection moulding cure process, can pass through cover half bottoming hole 7 and dynamic model bottoming hole 22, cover half cavity plate 6 and movable model central layer 8 are heated, to guarantee injection moulding curing molding mould needed thermosetting temperature in thermosets forming process.
The automatism isolation cutoff device of injection moulding curing molding mould by automatic cutoff fixed head 12, automatic cutoff supporting plate 13, oil pressure push rod 14, automatism isolation blank bar 17, case push rod 18, draw material guide rod 19 form, draw material guide rod 19 to be fixed on moving clamping plate 11, draw the motion of 19 pairs of automatism isolation cutoff devices of material guide rod to play the guiding role; Automatism isolation blank bar 17 is fixed in automatic cutoff fixed head 12, and is combined into one by trip bolt with automatic cutoff supporting plate 13.Automatism isolation blank bar 17 can be along drawing material guide rod 19 upward slidings under the active force of oil pressure push rod 14, the passage between pressure injection-moulded runner 1 and cover half cavity plate 6 can be opened by automatism isolation in its top, cut off charging, make thermosets in pressure injection-moulded runner 1 and the material automatism isolation in cover half cavity plate 6, guarantee thermosets (150 ℃) curing molding when being heated in cover half cavity plate 6.
Stripper apparatus is consisted of demoulding supporting plate 15, demoulding fixed head 16 and case push rod 18, and case push rod 18 is fixed on demoulding fixed head 16, and by holding screw, forms one with demoulding supporting plate 15.Between the demoulding supporting plate 15 of automatic cutoff fixed head 12 and stripper apparatus, be provided with stripping stroke spacing L.Stripping stroke spacing L is generally 2～3 times of injection moulding solidified forming product wall thickness, so that product takes out after injection moulding solidified forming.
The course of work of the present invention is achieved like this:
Thermosets can adopt automatic stuff-conveying machine to pass through the pressure injection-moulded runner 1 on solid plate 3, and the runner on cover half inserts 24 carries out injection moulding in the mold cavity in cover half cavity plate 6.Due on cover half fixed head 4, be provided with cover half cooling water runner 2, cover half cooling water runner 2 communicates with the cooling water runner on cover half inserts 24, form chilled(cooling) water return (CWR), in addition between cover half fixed head 4 and cover half cavity plate 6, be equipped with cover half thermal insulation board 5, therefore can make cover half fixed head 4 and cover half inserts 24 all the time in normal temperature state, guaranteed that the thermosets in injection molding channel 1 has good mobility.
After injection moulding finishes, be fixed on automatism isolation blank bar 17 on automatic cutoff fixed head 12 under the active force of oil pressure push rod 14, along drawing material guide rod 19 to move up, its top keeps apart the passage between pressure injection-moulded runner 1 and cover half cavity plate 6, cuts off charging.Meanwhile, by cover half bottoming hole 7 and dynamic model bottoming hole 22, to cover half cavity plate 6 and 8 heating of movable model central layer, when the temperature of cover half cavity plate 6 and movable model central layer 8 is heated to thermosets curing molding temperature (150 ℃), the product in the mold cavity in cover half cavity plate 6 can produce solidified forming.After products solidifying in mold cavity in model cavity plate 6 undetermined is shaped, the thrust that can make progress by oil pressure push rod 14, automatic cutoff fixed head 12 promotes demoulding fixed head 16 and moves upward, and be fixed on the case push rod 18 on demoulding fixed head 16, can be along drawing material guide rod 19 to move up, mold cavity by the case after injection moulding solidified forming 23 in cover half cavity plate 6, eject, thereby completed the overall process of thermosets injection moulding solidified forming technique.
