Description

Novel two-way sequence extrusion mechanism mould
Technical field
The present invention relates to a kind of novel two-way sequence extrusion mechanism mould, belong to mould of plastics field, be mainly used in ejecting of plastic.
Background technology
Injection moulding is a kind of mode of production that automaticity and production efficiency are higher, rational Design of Dies should be that plastic departs from cover half when die sinking, pack tightly on dynamic model, and follow dynamic model and return together, by the push rod on the ejecting mechanism of dynamic model side, plastic is ejected from dynamic model.Therefore to take into full account the position of die joint during Design of Dies, or design dynamic model, cover half die cavity different pattern drafts, or change the position of core, or first draw by push rod the aggregate measures such as the miscellaneous function on rear top to stay dynamic model side to realize plastic.But for the plastic of some shape, even if adopt above aggregate measures also cannot realize plastic stay dynamic model side, at this moment at cover half partial design ejecting mechanism, the thrust of ejecting mechanism will be relied on, pressure forces plastic to be separated with cover half, stays dynamic model side and follows dynamic model and return together and be ejected.But do the complexity increasing cover half part like this, and want extra power.Except arranging except ejecting mechanism in cover half part, the two-way sequence extrusion mechanism of fixed and moving mould can also be adopted, namely a die joint is increased in cover half part, guarantee when die sinking this die joint first spacing open, allow plastic first from the demoulding fixed mold, then, when main parting line somatotype, plastic can reliably stay dynamic model part, finally by dynamic model ejecting mechanism, plastic is released the demoulding.Mainly adopt the two-way sequence extrusion mechanism of three types both at home and abroad at present, i.e. spring, swinging hook type, the two-way sequence extrusion mechanism of slide block type, wherein spring two-way sequence extrusion mechanism generally normal employing spring eject and ensure that plastic stays dynamic model side with stop screw spacing, swinging hook type, slide block type two-way sequence extrusion mechanism Mould design and manufacturing is complicated, cost is high.The present invention is based on the two-way sequence extrusion mechanism of above-mentioned three types, creates a kind of novel two-way sequence extrusion mechanism mould in practice.
Summary of the invention
For swinging hook type, slide block type two-way sequence extrusion mechanism Mould design and manufacturing is complicated, cost is high problem, the invention provides the novel two-way sequence extrusion mechanism mould that a kind of structure is simple, design and manufaction cost is low.
Technical scheme of the present invention is: described novel two-way sequence extrusion mechanism mould comprises dynamic, cover half two parts, cover half is by top clamping plate, rubber, core, sprue bush, guide pillar, solid plate, screw, cover half push piece plate, spacer pin, puller plate is formed, sprue bush and top clamping plate and solid plate interference fit, core and solid plate interference fit, rubber is placed in the hole of solid plate and cover half push piece plate, guide pillar and solid plate interference fit through rubber, puller plate one end by screw fastening on solid plate side, top clamping plate and solid plate screw attachment, cover half push piece plate to be placed on guide pillar and movable, spacer pin is arranged on cover half push piece plate side, dynamic model is made up of moving platen, cushion block, push pedal, ejector sleeve, push rod, release link, ejector pin retaining plate, Bottom clamp plate, release link, push rod, ejector sleeve are placed in the hole of ejector pin retaining plate respectively, ejector pin retaining plate and push pedal screw attachment, release link, push rod, matched in clearance little between ejector sleeve and moving platen, moving platen, cushion block and Bottom clamp plate screw attachment.
Described rubber is cylindrical when not being stressed, in cydariform after being stressed, position, intermediate portion process a through hole for guide pillar with the use of; Ejector sleeve working end is processed with a hole, and the size in this hole and the working end size of core can form little matched in clearance.
Novel two-way sequence extrusion mechanism mould structure described in the present invention is simple, is easy to design and manufaction, can realizes the two-way sequence extrusion of plastic preferably.

Detailed description of the invention
Novel two-way sequence extrusion mechanism mould by moving, cover half two parts form, cover half is made up of top clamping plate 1, rubber 2, core 3, sprue bush 4, guide pillar 5, solid plate 6, screw 7, cover half push piece plate 17, spacer pin 8, puller plate 9, and dynamic model is made up of moving platen 16, cushion block 10, push pedal 12, ejector sleeve 13, push rod 18, release link 14, ejector pin retaining plate 15, Bottom clamp plate 11.
The cover half part of described mould, sprue bush 4 and top clamping plate 1 and solid plate 6 interference fit, core 3 and solid plate 6 interference fit, rubber 2 is placed in solid plate 6 with in the hole of cover half push piece plate 17, guide pillar 5 is with solid plate 6 interference fit and through rubber 2, puller plate 9 one end is fastened on solid plate 6 side by screw 7, top clamping plate 1 and solid plate 6 screw attachment, cover half push piece plate 17 to be placed on guide pillar 5 and movable, and spacer pin 8 is arranged on cover half push piece plate 17 side.
The dynamic model part of described mould, release link 14, push rod 18, ejector sleeve 13 are placed in the hole of ejector pin retaining plate 15 respectively, ejector pin retaining plate 15 and push pedal 12 screw attachment, release link 14, push rod 18, matched in clearance little between ejector sleeve 13 and moving platen 16, moving platen 16, cushion block 10 use screw attachment with Bottom clamp plate 11.
The rubber 2 of described mould is cylindrical when not being stressed, in cydariform after being stressed, position, intermediate portion process a through hole for guide pillar 5 with the use of.
Ejector sleeve 13 working end of described mould is processed with a hole, and the size in this hole and the working end size of core 3 can form little matched in clearance.
During dynamic, cover half two parts matched moulds of described mould, the guide pillar 5 of cover half side first contacts with the hole on moving platen 16 and coordinates, and rubber 2 is compressed, release link 14 drives push rod 18 and ejector sleeve 13 to reset, core 3 contacts with ejector sleeve 13 and coordinates simultaneously, treats that release link 14 resets completely, and closed die cavity is formed.The plastics of now melting are expelled in die cavity by nozzle of injector through sprue bush 4, after the plastics of melting are condensed into plastic, dynamic model side retreats under injector drives, the rubber of cover half side is replied promotion cover half push piece plate 17 and is released from core gradually by plastic owing to being elastically compressed, when spacer pin 8 move to collide with puller plate 9 time cover half push piece plate 17 stop motion, dynamic model continues the stop motion of motion one segment distance again, dynamic model side stayed by plastic now and condensation material, the push rod of injector promotes push pedal 12, ejector pin retaining plate 15, push rod 18, ejector sleeve 13 and release link 14 travel forward, plastic and condensation material eject by push rod 18 together with ejector sleeve 13 from die cavity.
