Aforesaid a kind of plastic mould that pours in down a chimney, it is characterized in that: described interlinked mechanism comprises the lower wedge block that is connected with the male model side, the upper voussoir that is connected with the master mold side, the movable plate that is connected with interior deckle board, in movable plate, be provided with fluting, being provided with in fluting can be along the slide block of fluting slip, described slide block one end is connected with spring, the other end of described slide block is provided with outer inclined-plane, described outer inclined-plane is relative with the lower wedge block inclined-plane that passes movable plate, be provided with opening at the slide block middle part, described opening is relative with the upper voussoir cheicers that passes movable plate and slide block opening near the end face of spring one side.
Aforesaid a kind of plastic mould that pours in down a chimney, it is characterized in that: the top at lower wedge block is provided with the inclined-plane.
Aforesaid a kind of plastic mould that pours in down a chimney, it is characterized in that: the bottom at upper voussoir is provided with cheicers.
Aforesaid a kind of plastic mould that pours in down a chimney is characterized in that: described opening is interior inclined-plane near the opening surface of spring one side,
Aforesaid a kind of plastic mould that pours in down a chimney is characterized in that: described lower wedge block is connected with the male model side by screw, and described upper voussoir is connected with the master mold side by screw, and described movable plate is connected with interior deckle board by screw.
The beneficial effects of the utility model are: the utility model pours in down a chimney plastic mould ejector retainner plate is not set, and simple in structure, weight is lighter, and cost of manufacture is also less, because simple in structure, the whole mould required time of clamping is also less simultaneously, and clamping is easy.In the utility model mould, be not provided with oil hydraulic cylinder, further provide cost savings, and avoid the generation of leakage of oil situation, pollution-free.Ejecting product during the utility model die sinking has been saved molding time in addition, has improved working (machining) efficiency.
Description of drawings
Fig. 1 is that the utility model pours in down a chimney the plastic mould front view.
Fig. 2 is that the utility model pours in down a chimney the plastic mould top view.
Fig. 3 is that Fig. 2 is along the generalized section of A-A line.
Fig. 4 is that Fig. 2 is along the generalized section of B-B line.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-4, a kind of plastic mould that pours in down a chimney, comprise male model 1 and master mold, it is characterized in that: also comprise interlinked mechanism, interior deckle board and jacking block 4, be provided with die 2 in male model 1, form product 3 at die 2 and be provided with the jacking block 4 that a circle separates with die 2 in die 2 bottoms, a described circle jacking block 4 is connected with the interior deckle board that is arranged on its outside, be provided with interlinked mechanism between male model 1 and master mold lateral wall, described interlinked mechanism is connected with interior deckle board by screw.
Described interlinked mechanism comprises the lower wedge block 5 that is connected with male model 1 side, the upper voussoir 6 that is connected with the master mold side, the movable plate 7 that is connected with interior deckle board, lower wedge block 5 can be connected with male model 1 side by two screws 15 during design, upper voussoir 6 can be connected with the master mold side by two screws 15, and described movable plate 7 is connected with interior deckle board by four screws 15.
In movable plate 7, be provided with fluting 8, being provided with in fluting 8 can be along the slide block 9 of fluting 8 slips, one end of described slide block 9 is connected with an end of spring 10, the other end of spring 10 is connected on the movable plate 7, and the other end of slide block 9 is provided with outer inclined-plane 11, is provided with inclined-plane 12 on the top of lower wedge block 5.Described outer inclined-plane 11 is relative with lower wedge block 5 inclined-planes 12 that pass movable plate 7, is provided with opening at slide block 9 middle parts, and described opening is interior inclined-plane 13 near the opening surface of spring 10 1 sides, is provided with cheicers 14 in the bottom of upper voussoir 6.Interior inclined-plane 13 is relative with upper voussoir 6 cheicers 14 that pass movable plate 7 and slide block 9 openings.
When the utility model pours in down a chimney the plastic mould die sinking, master mold moves up, male model 1 separates with master mold, the upper voussoir 6 that is connected to like this master mold side also moves up thereupon, and the lower wedge block 5 that is connected with male model 1 side maintains static, when the cheicers 14 of upper voussoir 6 caught on the interior inclined-plane 13 of slide block 9, slide block 9 and movable plate 7 integral body moved up.Movable plate 7 links to each other with some jacking blocks 4 by interior deckle board again, and by connecting move control, jacking block 4 can eject product die 2 easily like this.
Eject finish after, the outer inclined-plane 11 of slide block 9 contacts with the inclined-plane 12 that the top of lower wedge block 5 arranges, by being slidingly matched, so that slide block 9 is mobile to the extruding of spring 10 directions, when the oblique slip of slide block 9 and lower wedge block 5 finishes, the interior inclined-plane 13 of slide block 9 just in time gets out of the way the cheicers 14 of voussoir 6, and upper voussoir 6 separates with male model 1, and master mold can continue to move up and realizes the die sinking purpose like this.
In sum, the utility model pours in down a chimney plastic mould ejector retainner plate is not set, and simple in structure, weight is lighter, and cost of manufacture is also less, because simple in structure, the whole mould required time of clamping is also less simultaneously, and clamping is easy.In the utility model mould, be not provided with oil hydraulic cylinder, further provide cost savings, and avoid the generation of leakage of oil situation, pollution-free.Ejecting product during the utility model die sinking has been saved molding time in addition, has improved working (machining) efficiency.
Above demonstration and stated basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
