Description

A kind of two-way sequence extrusion mechanism mould
Technical field
The utility model relates to a kind of two-way sequence extrusion mechanism mould, belongs to mould of plastics field, is 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 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 utility model provides the two-way sequence extrusion mechanism mould that a kind of structure is simple, design and manufaction cost is low.
The technical solution of the utility model is: described two-way sequence extrusion mechanism mould comprises dynamic, cover half two parts, cover half is by top clamping plate, sprue bush, guide pillar, stop screw, solid plate, push piece plate, India rubber, core, screw is formed, sprue bush and top clamping plate and solid plate interference fit, coordinate with push piece sheet separation, core and solid plate interference fit, rubber is placed in can be freely movable in cover half plate hole, guide pillar and top clamping plate and solid plate interference fit through push piece plate, stop screw is connected through solid plate with push piece plate, top clamping plate is connected with solid plate trip bolt, dynamic model is made up of moving platen, cushion block, sprue puller, Bottom clamp plate, ejector sleeve, ejector pin retaining plate, push pedal, release link, screw, ejector sleeve, sprue puller, release link are placed in ejector pin retaining plate and run through moving platen, ejector pin retaining plate is connected with push pedal trip bolt, ejector pin retaining plate, push pedal, on Bottom clamp plate, connect Bottom clamp plate, cushion block, moving platen successively with screw.
Described ejector sleeve working end is processed with a hole, and the size in this hole and the working end size of core can form matched in clearance.
Two-way sequence extrusion mechanism mould structure described in the utility model is simple, is easy to design and manufaction, can realizes the two-way sequence extrusion of plastic preferably.

Detailed description of the invention
Described two-way sequence extrusion mechanism mould comprises dynamic, cover half two parts, cover half is made up of top clamping plate 2, sprue bush 1, guide pillar 3, stop screw 4, solid plate 5, push piece plate 6, rubber 18, core 15, screw, and dynamic model is made up of moving platen 7, cushion block 8, sprue puller 14, Bottom clamp plate 9, ejector sleeve 13, ejector pin retaining plate 12, push pedal 11, release link 19, screw.
The cover half part of described mould, sprue bush 1 and top clamping plate 2 and solid plate 5 interference fit, with push piece plate 6 matched in clearance, core 15 and solid plate 5 interference fit, rubber 18 is placed in can be freely movable in solid plate 5 hole, guide pillar 3 is with top clamping plate 2 and solid plate 5 interference fit and through push piece plate 6, stop screw 4 is connected through solid plate 5 with push piece plate 6, and top clamping plate 2 is connected with trip bolt with solid plate 5.
The dynamic model part of described mould, ejector sleeve 13, sprue puller 14, release link 19 are placed in ejector pin retaining plate 12 and run through moving platen 7, ejector pin retaining plate 12 is connected with trip bolt with push pedal 11, ejector pin retaining plate 12, push pedal 11, on Bottom clamp plate 9, connect Bottom clamp plate 9, cushion block 8, moving platen 7 successively with screw.
Described ejector sleeve 13 working end is processed with a hole, and the size in this hole and the working end size of core 15 can form matched in clearance.
During dynamic, cover half two parts matched moulds of described mould, the guide pillar 3 of cover half side first contacts with the hole on moving platen 7 and coordinates, rubber 18 is compressed, release link 19 drives ejector sleeve 13 and sprue puller 14 to reset, core 15 contacts with ejector sleeve 13 and coordinates simultaneously, treat that release link 19 resets completely, closed die cavity is formed.The plastics of now melting are expelled in die cavity by nozzle of injector through sprue bush 1, 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 push piece plate 6 and is released from core 15 gradually by plastic owing to being elastically compressed, push piece plate 6 stop motion when limitting screw 4 to move to collide with solid plate 5, 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 11, ejector pin retaining plate 12, ejector sleeve 13, sprue puller 14 and release link 19 travel forward, plastic and condensation material eject by ejector sleeve 13 together with sprue puller 14 from die cavity, manual taking-up plastic and condensation material.
