Detailed description of the invention
Refer to Fig. 1 to Fig. 5, foam mold, including the mine dam 92 of upper baffle plate 10, upper framed 20, core rod 30, lower mould bottom plate 40, core rod set 50, steam erosion control allotter 91, annular.
Baffle plate 10 on this, upper framed 20, core rod 30, lower mould bottom plate 40 are sequentially arranged up and down.On this, baffle plate 10 and upper framed 20 can be solidly installed in mounting or dismounting, and this core rod 30 and lower mould bottom plate 40 can be solidly installed in mounting or dismounting.On this, baffle plate 10 surrounds steam room 71 with upper framed 20, separately sets the upper steam inlet hole 72 that can turn on extraneous and upper steam room 71 and upper steam portals 73；This core rod 30 and lower mould bottom plate 40 surround lower steam room 74, separately set the lower steam inlet hole 75 that can turn on extraneous and lower steam room 74 and lower steam portals 76.This steam erosion control allotter 91, annular mine dam 92 be located at baffle plate and upper framed between.Their structure and connection can refer to background technology.
This core rod 30 includes base 31, be installed on base 31 core part 32 and be fixed in the base plate 33 under base 31, this base plate 33 periphery stretches out outside base 31.On this, framed 20 include the perisporium 22 of roof 21 and the upper peripheral edge affixed roof 21 of sealing.This perisporium 22 adaptation from top to down is socketed in outside base 31 and cover direct type core 32, and this base 31, core part 32 and upper framed 20 cooperatively form die cavity 60.Separately setting can from the extraneous feeder channel 61 connecting die cavity 60；This core rod 30 is provided with the steam flow channel of can communicate extraneous and die cavity 60, this steam flow channel includes at least one steam inlet and some steam (vapor) outlets, this steam (vapor) outlet communicates with die cavity 60, and this steam flow channel and the isolation of lower steam room 74 are arranged, as steam inlet is arranged on base 31 side.
The inwall of this perisporium 22 is arranged with the air discharge duct 23 passing to perisporium 22 bottom face, the air discharge duct 23 of the perisporium 22 of this socket base 31 and base 31 outer wall coordinate the part constituting the exhaust passage that can turn on die cavity 60 and the external world, upper framed and when core rod is in matched moulds state: air discharge duct 23 upper end of the perisporium of this socket base 31 is slightly below base 31 upper surface, and those skilled in the art can be poor according to foamed product Decision Height.In order to improve finished product rate, this core part 32 has a core part part and and is fixed in the middle base under core part part, and this middle base is fixed on base, and this base periphery stretches out outside middle base, to form ring-shaped step.In foam-formed process, the base of upper framed perisporium socket core rod, and the two incomplete matched moulds, now air discharge duct upper end is slightly above base, going up interval between framed and core rod set, by feeder channel to injection material in die cavity, the air of die cavity discharges through air discharge duct, interval.After foam injects, upper framed and core rod relative motion again is to realize complete matched moulds, and now air discharge duct top is positioned under base end face.
This core rod set 50 is socketed base 31 and is supported by base plate 33, and on this, framed 20 perisporium 22 bottom faces are supported by and overlap on 50 at core rod.Above-mentioned air discharge duct is vertically arranged and height overlaps the spacing of end face less than base top end face and core rod.
It is additionally provided with at least one through hole 81 that can run through baffle plate 10 and the upper roof of framed 20 21, this each through hole 81 all arranges push rod 82, among the present embodiment, feeder channel 61 is arranged at baffle plate 10 center and upper framed 20 centers, this through hole 81 is provided with four, four four corners being arranged in the rectangle being centrally located at feeder channel.This push rod 82 lower end evagination is set as convex shoulder 83；This through hole 81 lower port is set as the reaming 84 of adaptive convex shoulder 83.In concrete structure, this through hole 81 includes being located at the second hole section that the first hole section and of baffle plate 10 is located at the roof 21 of framed 20, this first hole section and the second hole section alignment (centrage alignment), and this reaming 84 is located at bottom the second hole section；Fixed sliding sleeve 85 in this second hole section, this sliding sleeve 85 top end face and the second hole section top end face flush, and this sliding sleeve 85 bottom face and reaming top end face flush, and this sliding sleeve 85 internal diameter and the first hole section internal diameter are equal, sliding sleeve inwall and the first hole section aligning inner；This push rod 82 can pierce into sliding sleeve 85 from bottom to top and the second hole section is positioned at reaming to convex shoulder 83 adaptation, and now: push rod 82 upper end is stretched out on baffle plate 10, convex shoulder bottom surface and roof bottom surface flush to ensure foamed molded product external form.Preferably, framed 20 top projection protuberances 24 on this, this second hole section is through protuberance 24, and on this, baffle plate 10 bottom surface and protuberance 24 end face are abutted against；Second hole section upper port sets annular breach, this annular breach surrounds sliding sleeve and makes annular breach constitute cannelure, arranges sealing ring 86 in this cannelure, and sealing ring 86 seals and surrounds outside sliding sleeve, sealing ring 86 seals upper baffle plate 10 bottom surface and protuberance 24 end face, to seal off upper steam room and die cavity.
The part on baffle plate of stretching out of this push rod sets stopper 87, and the another spring 88 that arranges is socketed the part stretched out of push rod and contact between stopper and upper baffle plate.Another arranging one restraint portion, this relative board in restraint portion is fixed, and detent just going up in push rod top.
In knockout course: cylinder drive upper baffle plate with upper framed together with upwards movable, now restraint portion also do not touched by push rod, and therefore push rod is upwards movable together；Upwards movable to push rod end touching restraint portion, now push rod is restricted cannot continue up activity, but upper baffle plate with upper framed still together with upwards movable, spring starts pressurized accumulation of energy, push rod and upper baffle plate, upper framed beginning with relative motion, this relative motion makes push rod can eject foamed product.After they reset, this spring can drive push rod to reset.
The above, be only this utility model preferred embodiment, therefore can not limit the scope that this utility model is implemented according to this, and the equivalence namely made according to this utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that this utility model is contained.
