Description

A kind of plastic bowl mould

Technical field

The utility model relates to a kind of plastic bowl mould, belongs to mould of plastics field, is mainly the structural design of mould.

Background technology

Common plastic bowl in life, its mould structure generally adopts that core is inserted, die plate insert, although insert, be to be placed on separately in template, but what core was inserted, die plate insert is basic still whole, work in-process, finds that mould complicated processing cost is high, in use procedure, occur that whole core is inserted or die plate insert damage replacement cost is high, and change inconvenient.For a multi-cavity mold and complicated mould, the processing charges of mould is higher especially, damages and causes the whole replacement cost of inserting of mould higher.

Summary of the invention

In order to overcome, whole core is inserted, the processed complex of die plate insert and cost high, damage replacing inconvenient high with cost, the utility model provides a kind of plastic bowl mould, and the core of this mould, die cavity adopt the combined type of edge spelling, one mould two cavity configurations, adopt the two somatotypes of spring somatotype pull bar spacing.

The technical solution of the utility model is: described plastic bowl mould comprises moving, cover half two parts, cover half is by sprue bush, top clamping plate, limit pull rod, Compress Spring one, solid plate, cavity block one, packing ring, nut, cavity block two, guide pin bushing, the formations such as screw, sprue bush and top clamping plate pass through screw attachment, limit pull rod band head end is placed in top clamping plate, guide pin bushing and solid plate interference fit, cavity block one and cavity block two interference fit and solid plate be interference fit again, Compress Spring one is placed between top clamping plate and solid plate, solid plate is porose locates for spring, limit pull rod is through spring and solid plate, its other end is processed with screw thread and connects use with nut for placing packing ring, dynamic model is by moving platen, push piece plate, core, plastic bowl, 10 millimeters of screws of diameter, push rod, core fixing plate, cushion block, Bottom clamp plate, Compress Spring two, release link, long spiro nail, push pedal, ejector pin retaining plate, guide pillar, the formations such as push pedal guide pillar, push rod, release link is placed in locating hole on ejector pin retaining plate, push pedal and ejector pin retaining plate screw attachment, push pedal guide pillar and Bottom clamp plate screw attachment, Compress Spring two is placed in release link the locating hole with moving platen, core is placed in core fixing plate locating hole, core fixing plate and moving platen screw attachment, push rod small end is processed with screwed hole, with 10 millimeters of screw attachment push piece plates of diameter and push rod, guide pillar interference is placed in moving platen, moving platen, cushion block connects with long spiro nail with Bottom clamp plate, push pedal and ejector pin retaining plate can move along push pedal guide pillar.

Plastic bowl mould structure described in the utility model is simple, is easy to manufacture, and is easy to change core, cavity block, adopts the two somatotypes of spring somatotype pull bar spacing more convenient than drawplate type spacing somatotype, swinging hook type spacing somatotype.

Accompanying drawing explanation

Fig. 1 is the utility model plastic bowl mode host visual pattern, and Fig. 2 is left view, and Fig. 3 is top view.

The specific embodiment

Plastic bowl mould by moving, cover half two parts form, cover half consists of sprue bush 24, top clamping plate 1, limit pull rod 2, Compress Spring 1, solid plate 4, cavity block 1, packing ring 7, nut 8, cavity block 2 22, guide pin bushing 23 etc., and dynamic model consists of moving platen 25, push piece plate 20, core 19, plastic bowl 21,10 millimeters of screws 6 of diameter, push rod 9, core fixing plate 18, cushion block 10, Bottom clamp plate 12, Compress Spring 2 13, release link 14, long spiro nail 15, push pedal 11, ejector pin retaining plate 16, guide pillar 17, push pedal guide pillar 26 etc.

Described plastics welding bell cover half part, sprue bush 24 passes through screw attachment with top clamping plate 1, limit pull rod 2 band head ends are placed in top clamping plate 1, guide pin bushing 23 and solid plate 4 interference fit, cavity block 1 and cavity block 2 22 interference fit and solid plate 4 be interference fit again, Compress Spring 1 is placed between top clamping plate 1 and solid plate 4, solid plate 4 is porose for spring 3 location, limit pull rod 2 is through spring 3 and solid plate 4, and its other end is processed with screw thread and connects use for placing packing ring 7 with nut 8.

Described plastics welding bell dynamic model part, push rod 9, release link 14 is placed in locating hole on ejector pin retaining plate 16, push pedal 11 and ejector pin retaining plate 16 use screw attachment, push pedal guide pillar 26 and Bottom clamp plate 12 use screw attachment, Compress Spring 2 13 is placed in release link 14 locating hole with moving platen 25, core 21 is placed in core fixing plate 18 locating holes, core fixing plate 18 and moving platen 25 use screw attachment, push rod 9 small ends are processed with screwed hole, with 10 millimeters of screws of diameter 6, connect push piece plate 20 and push rod 9, guide pillar 17 interference are placed in moving platen 25, moving platen 25, cushion block 10 connects with Bottom clamp plate 12 use long spiro nails 15, push pedal 11 and ejector pin retaining plate 16 can move along push pedal guide pillar 26.

Described orifice ring mould, moving, during cover half two parts matched moulds, first the guide pillar 17 of dynamic model contacts cooperation with the guide pin bushing 23 of cover half, after complete matched moulds, molten plastic enters runner and die cavity by sprue bush 24, treat that plastics are condensed into plastic bowl 21, after, dynamic model starts to retreat under injector drives, 21 armfuls of plastic bowls move with dynamic model one side on core 19, cover half one side Compress Spring 1 recovers solid plate 4 and top clamping plate 1 automatically to separate and start somatotype for the first time automatically, sprue is extracted with dynamic model and is moved from sprue bush 24 with the condensing part of runner, stop motion when solid plate 4 moves to packing ring 7, now the condensing part of sprue and runner and plastic bowl 21 are broken, start twice parting, can manually take out condensing part, dynamic model is the stop motion of slow astern segment distance again, and the push rod of injector promotes push pedal 11, ejector pin retaining plate 16 and push rod 9 and travels forward, and push rod 9 drives push piece plate 20 that plastic bowl 21 is fallen down from core 19.During the push rod rollback of injector, release link 14 automatic traction ejector pin retaining plate 16, push rod 9 under Compress Spring 2 13 effects are got back to original position with push pedal 11 and are started next injection process.
