Abstract
The utility model relates to a drawn needle type mould. A fixed mould core of the mould is fixed on a fixed mould rack; a movable mould core is fixed on a movable mould rack; the molding surface of the fixed mould core and the molding surface of the movable mould core are opposite and parallel; a balancing rack is arranged on the movable mould rack; one end of a guide rail is arranged on the movable mould rack; the other end of the guide rail is arranged on the balancing rack; a slide block is arranged on the guide rail; a drawn needle plate is connected with the slide block; a drawn needle on the drawn needle plate is parallel with the molding surfaces of the fixed mould core and the movable mould core; a thimble plate is arranged on the movable mould rack; a thimble on the top needle plate is vertical to the molding surfaces of the fixed mould core and the movable mould core; a push plate is arranged on the rear part of the thimble plate; one end of a slide rod is connected with the slide block; and the other end of the slide rod is connected with the push rod. When the drawn needle type mould is adopted, as the slide block does not move along the fixed mould rack, the needle drawing is not performed immediately in mould opening and can be performed after a product is cooled so as to avoid the swelling phenomenon of a needle hole and improve the qualification rate of the product; meanwhile, the slide block has large stroke; the drawn needle can be lengthened to increase the number of mold cavities of mould products and improve the yield; in addition, two ends of the guide rail are fixed and balanced and have even stress, so the service life of the mould can be prolonged.
Description
Affiliated technical field
The utility model relates to a kind of drawn needle formula mould, is mainly used in the injecting products of producing the band pin hole.
Background technology
Usually, utilize the plastic product of injection machine production band pin hole, need drawn needle formula mould, this mould mainly adopts the Angle Pin structure, and promptly the Angle Pin on the cover half frame links to each other with slide block on the guide rail that is arranged on the dynamic model frame, when die sinking, the cover half core separates with moving-mould-core, Angle Pin drives slide block, moves together with the drawn needle plate is parallel, drawn needle is extracted out from mold cavity and is separated with product.The mould of this structure because of drawn needle and Angle Pin, cover half frame move simultaneously, when die sinking, begins drawn needle immediately, and this moment, the product temperature inside was too high, and pin is extracted the back pin hole out and can be swollen, even stops up pin hole, more scrap occurs; Simultaneously, limit by the Angle Pin structure, the stroke of slide block is little, and output is not high.
Summary of the invention
The purpose of this utility model provides and can improve product yield, can improve a kind of drawn needle formula mould of product percent of pass again.
The technical scheme that the utility model is taked is: a kind of drawn needle formula mould comprises cover half frame and cover half core, dynamic model frame and moving-mould-core, guide rail and slide block, drawn needle plate, ejector retainner plate, push pedal; The cover half core is fixed on the cover half frame, and moving-mould-core is fixed on the dynamic model frame, and the cover half core is relative with the forming surface of moving-mould-core and parallel; Guide rail is located on the dynamic model frame, and slide block is located on the guide rail; The drawn needle plate is connected with slide block; Drawn needle on the drawn needle plate is parallel with the forming surface of cover half core, moving-mould-core; Ejector retainner plate is located on the dynamic model frame, and the thimble on the ejector retainner plate is vertical with the forming surface of cover half core, moving-mould-core; Push pedal is located at the rear portion of ejector retainner plate; It is characterized in that it includes slide bar, an end of slide bar links to each other with slide block, and the other end links to each other with push pedal.
Described a kind of drawn needle formula mould, it includes balancing stand, and balancing stand is fixed on the dynamic model frame, and an end of guide rail is located on the dynamic model frame, and the other end is located on the balancing stand.
Described a kind of drawn needle formula mould, an end of guide rail is fixed on the dynamic model frame, and the other end is fixed on the balancing stand, and slide block is movably arranged on the guide rail, and slide block can slide on guide rail.
Described a kind of drawn needle formula mould, slide block is fixed on the guide rail, and guide rail one end is actively installed on the dynamic model frame, and the other end is actively installed on the balancing stand, and guide rail can slide on dynamic model frame and balancing stand.
Adopt the utility model, because slide block is not along with the motion of cover half frame, drawn needle does not carry out immediately during die sinking, can wait until after the product cooling drawn needle again, just can not produce the pin hole phenomenon of swelling, improved the qualification rate of product, simultaneously, ram travel is big, and drawn needle can extend, increase mould product die cavity quantity, improve output; In addition, the guide rail two ends are fixed and balance, and are stressed even, can increase the service life of mould.
Description of drawings
Fig. 1 is a schematic top plan view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Comprise cover half frame 1 and cover half core 2, dynamic model frame 9 and moving-mould-core 3, guide rail 6 and slide block 5, balancing stand 7, drawn needle plate 4, slide bar 8, ejector retainner plate 11, push pedal 10 with reference to Fig. 1, this drawn needle formula mould; Cover half core 2 is fixed on the cover half frame 1, and moving-mould-core 3 is fixed on the dynamic model frame 8, and cover half core 2 is relative with the forming surface of moving-mould-core 3 and parallel; Balancing stand 7 is fixed on the dynamic model frame 9, and an end of guide rail 6 fixedly is located on two sides of dynamic model frame 9, and the other end of guide rail 6 is fixed on the balancing stand 7; Slide block 5 is actively installed on the guide rail 6 and can slides on guide rail 6; Drawn needle plate 4 is connected with slide block 5; Drawn needle on the drawn needle plate 4 is parallel with the forming surface of cover half core 2, moving-mould-core 3; Ejector retainner plate 11 is located on the dynamic model frame 9, and the thimble on the ejector retainner plate 11 is vertical with the forming surface of cover half core 2, moving-mould-core 3; Push pedal 10 is located at the rear portion of ejector retainner plate 11; One end of slide bar 8 links to each other with slide block 5, and the other end links to each other with push pedal 10.
During use, when the mould die sinking, cover half core 2 separates with moving-mould-core 3, Deng the cooling of the product in mold cavity certain hour, product is unlikely to after the expansion, promotes push pedal 10 by cylinder or oil cylinder again, slide bar 8 drives slide blocks 5 parallel sliding on guide rail 6, slide block 5 drives drawn needle plate 4 parallel in the lump moving, and drawn needle is drawn to from mold cavity with product separates fully; Afterwards, push pedal 10 promotes ejector retainner plate 11, and the thimble on the ejector retainner plate 11 expects that product and water product eject promptly to finish use from mold cavity.
In above-mentioned, also can adopt slide block 5 is fixed on the guide rail 6, one end of guide rail 6 is actively installed on the dynamic model frame 9, the other end of guide rail 6 is actively installed on the balancing stand 7, and the mode that guide rail 6 can slide on dynamic model frame 9, equally, it is parallel in the lump mobile also to drive drawn needle plate 4, realizes drawn needle is drawn to the purpose of separating fully with product from mold cavity.
In the utility model, slide bar 8 links to each other with push pedal 10, slide bar 8 is arranged on dynamic model frame 9 one sides, can increase the stroke of slide block 5 on guide rail 6, the drawn needle that can extend increases mould product die cavity quantity, improve output, and owing to have balancing stand 7, slide bar 8 makes slide block 5 stressed even on guide rail 6, the service life that can improve mould.
