Abstract
The invention relates to a joint push-out mechanism plastic die and belongs to the field of plastic dies. The die comprises two parts, namely a movable die and a fixed die, wherein in the fixed die part, a die cavity is connected with a fixed template through a screw; a pouring gate sleeve is in interference fit with the die cavity and the fixed template; a guide sleeve is in interference fit with the fixed template; a fixed die seat plate is connected with the fixed template through a screw; a positioning ring is connected with the fixed die seat plate through a screw; in the movable die part, a push block is arranged in the die core in a connection manner through a screw push rod and can slide; the screw push rod, a resetting rod, a push rod, a push rod fixing plate and a push plate are connected through screws to form a push-out mechanism; the push-out mechanism can move between the die core and a movable template; a guide column is in the interference fit with the movable template; the die core is connected with the movable template through a screw; the movable template, a cushion block and a movable die seat plate are connected through screws; a limiting screw is fastened on the movable die seat plate. According to the technical scheme, the joint push-out mechanism plastic die is simple in structure, easy to manufacture and convenient to use and can well eject a plastic element which has a large appearance size and a thin wall so as to easily deform.
Description
Technical field
The present invention relates to a kind of associating ejecting mechanism Mold for Plastics, belong to mould of plastics field, be mainly used in that appearance and size is large and the thin yielding plastic of wall ejects.
Background technology
In life, the lid of common plastic lunch box and the appearance and size of box body is much larger than wall thickness dimension, for ejecting yielding plastic as this large and wall is thin, is to want attentional selection ejecting mechanism at Design of Dies, generally conventional push piece plate release.Because push piece plate is larger, after service time length or release often, push piece plate connects gap between the screw of use and the mould parts of dynamic model one side and occurs that wearing and tearing become large, there is energy imbalance at reseting procedure because wearing clearance becomes the reason such as large and inhomogeneous in push piece plate, cause itself and mold cores surface to have friction, there is scratch phenomenon in whose surfaces, affects the surface quality of moulding plastic.
Summary of the invention
Thin and the yielding plastic of wall for better moulding appearance and size is large, the invention provides a kind of simple in structure, be easy to manufacture, the associating ejecting mechanism Mold for Plastics of handiness.
Technical scheme of the present invention is: described associating ejecting mechanism Mold for Plastics comprises active and inactive mold two parts, cover half is made up of centring ring, top clamping plate, sprue bush, solid plate, die cavity, guide pin bushing, die cavity and solid plate screw attachment, interference fit between sprue bush and die cavity and solid plate, guide pin bushing and solid plate interference fit, top clamping plate and solid plate screw attachment, centring ring and top clamping plate screw attachment; Dynamic model is made up of core, moving platen, guide pillar, ejector pin retaining plate, release link, push rod, screw push rod, push pedal, pushing block, stop screw, cushion block, Bottom clamp plate, pushing block is connected and is placed in core and slidably by screw push rod, screw push rod, release link, push rod, ejector pin retaining plate and push pedal form ejecting mechanism by screw attachment, ejecting mechanism can move between core and moving platen, guide pillar and moving platen interference fit, core and moving platen screw attachment, moving platen, cushion block and Bottom clamp plate screw attachment, stop screw is anchored on Bottom clamp plate.
Associating ejecting mechanism Mold for Plastics described in the present invention is simple in structure, is easy to manufacture, easy to use, realizes preferably that appearance and size is large and the thin yielding plastic of wall ejects.
Accompanying drawing explanation
Figure is associating ejecting mechanism Mold for Plastics structural representation of the present invention.
The specific embodiment
Combining in the drawings ejecting mechanism Mold for Plastics is made up of active and inactive mold two parts, cover half is made up of centring ring 1, top clamping plate 3, sprue bush 2, solid plate 4, die cavity 16, guide pin bushing 19, and dynamic model is made up of core 15, moving platen 5, guide pillar 6, ejector pin retaining plate 7, release link 8, push rod 13, screw push rod 14, push pedal 12, pushing block 18, stop screw 11, cushion block 9, Bottom clamp plate 10.
Described associating ejecting mechanism Mold for Plastics cover half part, die cavity 16 and solid plate 4 use screw attachment, interference fit between sprue bush 2 and die cavity 16 and solid plate 4, guide pin bushing 19 and solid plate 4 interference fit, top clamping plate 3 and solid plate 4 use screw attachment, centring ring 1 and top clamping plate 3 screw attachment.
Described associating ejecting mechanism Mold for Plastics dynamic model part, pushing block 18 is connected and is placed in core 15 and slidably by screw push rod 14, screw push rod 14, release link 8, push rod 12, ejector pin retaining plate 7 form ejecting mechanism with push pedal 12 by screw attachment, ejecting mechanism can motion between core 15 and moving platen 5, guide pillar 6 and moving platen 5 interference fit, core 15 and moving platen 5 use screw attachment, moving platen 5, cushion block 9 and Bottom clamp plate 10 use screw attachment, stop screw 11 is anchored on Bottom clamp plate 10.
Described associating ejecting mechanism Mold for Plastics, when active and inactive mold two parts matched moulds, ejecting mechanism is reset to stop screw place 11, molten plastic is entered the die cavity being made up of die cavity 16 and core 15 by sprue bush 2, treat that plastics are condensed into plastic 17, motion certain distance after dynamic model one side direction, plastic 17 wraps on core 15, travel forward when injector push rod drives the ejecting mechanism of dynamic model, the pushing block 18 that plastic 17 drives at push rod 13 and screw push rod 14 ejects jointly; In the time that dynamic model carries out again matched moulds, solid plate 4 contacts with release link 8, and release link 8 drives ejecting mechanism rollback, ejecting mechanism stop motion in the time that solid plate 4 contacts with moving platen 5.
