The die comprises a cavity plate, a core plate with a thermal pouring channel, a lower fixing plate fixedly connected with the core plate, an ejection plate arranged in a sliding way on the lower fixing plate, two pairs of pressure plates, two elastic blocks, two pull rods and a return pin, wherein, two ends of each pressure plate are respectively locked on two side surfaces of the core plate and the two side surfaces of lower fixing plate through screw parts, a groove is formed on the side surface of each pressure plate, which faces to the core plate, and the groove is provided with an inner inclined surface formed on the pressure plate in a position close to the cavity plate; the two elastic blocks are internally arranged on two sides of the ejection plate respectively, and the top end of each elastic block, which protrudes out of the corresponding groove, comprises an outer inclined surface; one end of each pull rod is fixed to the side surface of the cavity plate, and the other end of each pull rod is arranged between two pressure plates; and one end of the return pin is fixed to the ejection plate through an elastic element, and the other end of the return pin penetrates through the ejection plate and the core plate and is propped against to the lower part of the cavity plate. The die provided by the utility model has a simple structure, dispenses with an additional power source, shortens the forming cycle and enhances the stability of die movement.
Description
Technical field
The utility model relates to a kind of injection mold, specifically a kind of have pour in down a chimney the into mould of plastic structure.
Background technology
Have the mould that pours in down a chimney the hot runner structure liftout plate all is set on solid plate usually, liftout plate ejects from solid plate near hot runner and with product during die sinking, and liftout plate is realized return early away from hot runner during matched moulds.Existing liftout plate adopts Driven by Hydraulic Cylinder to eject and return morning with realization more, adopts comparatively heaviness of Driven by Hydraulic Cylinder liftout plate one side hydraulic structure self, needs to be provided with the comparatively inconvenience of extra power source on the other hand.
The utility model content
Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, provides a kind of folding mould action that directly utilizes mould just can realize ejecting the mould with revert action morning of liftout plate automatically.
The utility model discloses a kind of have pour in down a chimney the into mould of plastic structure, comprise caster; Be provided with the male model plate of hot runner; The bottom plate that is fixedly connected with described male model plate; Be slidingly arranged in the liftout plate on the described bottom plate; Two pairs of pressing plates, two ends are locked in the two sides of described male model plate and bottom plate respectively by screw piece, this hold-down plate surface is provided with groove to the side of described male model plate, and this groove is provided with an interior inclined-plane in this pressing plate near described caster place; Two bullet pieces are located at the both sides of described liftout plate in respectively, and the top that this bullet piece protrudes described groove comprises an outer inclined-plane; Two pull bars, the side of the fixing described caster of an end, the other end is arranged between two pressing plates; Return pin, an end is fixed on the described liftout plate by elastic component, and the other end passes described liftout plate and described male model plate withstands on described caster below.
More excellent, described bullet piece is arranged in the described liftout plate by spring.
More excellent, described elastic component is excellent power glue or spring.
Compared with prior art, the utility model utilizes the folding of caster just can realize ejecting and return early of liftout plate, and is simple in structure, do not need extra power source, accelerated the stability that molding cycle and mould move.

The specific embodiment
For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
Please consult Fig. 1 and Fig. 2 simultaneously, a kind of have pour in down a chimney the into mould of plastic structure, comprise caster 11; Be provided with the hot runner male model plate 12 of (figure does not show); The bottom plate 14 that is fixedly connected with described male model plate 12; Be slidingly arranged in the liftout plate 13 on the described bottom plate 14; Two pairs of pressing plates 2, two ends are locked in the two sides of described male model plate 12 and bottom plate 14 respectively by screw piece, this pressing plate 2 is provided with groove 21 in the face of the side of described male model plate 12, and this groove 21 is provided with an interior inclined-plane 211 in this pressing plate 2 near described caster 11 places; Two bullet pieces 131, by being located at the both sides of described liftout plate 13 in the spring 3, the top that this bullet piece 131 protrudes described groove 21 comprises an outer inclined-plane 1311 respectively; The side of two fixing described casters 11 of pull bar 111, one ends, the other end is arranged between two pressing plates 2; Return pin 132, one ends are fixed on the described liftout plate 13 by excellent power glue 133, and the other end passes described liftout plate 13 and described male model plate 12 withstands on described caster 11 belows.
See also Fig. 3, be die opening state of the present utility model structural representation for the moment.Described caster 11 drives on the described pull bar 111 and draws, and described pull bar 111 negotiates with described bullet piece 131, thereby makes described caster 11 separate with described male model plate 12; Fit until the outer inclined-plane 1311 of described bullet piece 131 and the interior inclined-plane 211 of described groove 21.
Please continue to consult Fig. 4, be the structural representation of complete die opening state of the present utility model.Described caster 11 drives in described pull bar 111 continuation and draws, the interior inclined-plane 211 of described groove 21 will give outer inclined-plane 1311 pressure of described bullet piece 131, make when described bullet piece 131 is depressed into the parallel sided of its free end and described liftout plate 13, described pull bar 111 is separated with described bullet piece 131, thereby finishes the complete die sinking of this mould.
During matched moulds, described caster 11 can be suppressed described return pin 132, makes the revert action of described liftout plate 13, thereby finishes the matched moulds of this mould.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by claim of the present utility model.
