Description
Technical field
A kind of injection mold base double-guide mechanism is the utility model is related to, belongs to injection-moulding device field.
Background technology
Traditional injection moulding mould is oriented to using cylindrical guides, guide pin bushing slide-and-guide, and due to there is certain interval, positioning precision is not
Height, in order to improve closing precision, precise locating mechanism is also designed, adds manufacture die cost.
Utility model content
The guider of mould bases is mainly made up of guide pillar, guide pin bushing part.Ensure dynamic model, cover half correct phase during mould matched moulds
To motion, die life is improved.It is that gap coordinates positioning precision low because traditional guide pillar, guide pin bushing coordinate, in order to improve
Positional precision when high accuracy, long-service die matched moulds, design a kind of guide-localization precision height, the low guide-localization machine of cost
Structure.
For above-mentioned technical problem, the purpose of the present invention is:Propose a kind of installation, convenient disassembly, can improve
The guide-localization mechanism of mould base of injection mould matched moulds positioning precision.
The injection mold base double-guide mechanism, including the first screw, Bottom clamp plate, guide pillar, the first guide pin bushing, dynamic model
Plate, ball retainer, elastic collar, ball, elastic collar, solid plate, the second guide pin bushing, top clamping plate, the second screw；First spiral shell
Nail fixes Bottom clamp plate and moving platen；Guide pillar back segment is cased with ball retainer, and ball retainer hole is embedded with ball, and ball is protected
Frame back segment outer cover is held in the first guide pin bushing, the first guide pin bushing is in dynamic model plate hole；Elastic collar is stuck in the first guide pin bushing outer surface card
In groove；Guide pillar face of cylinder leading portion is in the second dowel hole；Second guide pin bushing outer surface is in cover half plate hole；Second screw is by solid plate
It is connected with top clamping plate.
The guide pillar leading portion and the second guide pin bushing are combined with certain interval.
The guide pillar back segment and ball, the first guide pin bushing, solid plate hole between have 0.01~0.02 the magnitude of interference.
Conventional injection mould mould bases uses slide-and-guide, it is ensured that active and inactive mold matched moulds is oriented to and the effect of positioning, but positioning accurate
Degree is not high, and mould and die accuracy is affected.This mould mould bases uses dual-guiding structure, improves the positioning precision after mould bases matched moulds,
Improve mould and die accuracy.The needs of guiding and fine positioning when the utility model meets mould matched moulds, simplify mould structure, carry
High position precision, make mould production efficiency high, reduce production cost.
Brief description of the drawings
Accompanying drawing 1 is injection mould bases matched moulds status architecture schematic diagram of the invention；
Accompanying drawing 2 is injection mould bases die opening state structural representation of the invention；
Wherein 1, the first screw, 2, Bottom clamp plate, 3, guide pillar, the 4, first guide pin bushing, 5, moving platen, 6, ball retainer, 7,
Elastic collar, 8, ball, 9, elastic collar, 10, solid plate, the 11, second guide pin bushing, 12, top clamping plate, the 13, second screw.
Embodiment
Accompanying drawing 1 is injection molding mould bases double-guide mechanism described in the utility model, including the first screw 1, Bottom clamp plate
2nd, guide pillar 3, the first guide pin bushing 4, moving platen 5, ball retainer 6, elastic collar 7, ball 8, elastic collar 9, solid plate 10, second
Guide pin bushing 11, top clamping plate 12, the second screw 13；First screw 1 fixes Bottom clamp plate and moving platen 5；The back segment of guide pillar 3 is cased with rolling
Pearl retainer 6, the hole of ball retainer 6 are embedded with ball 8, and in the first guide pin bushing 4, first leads the back segment outer cover of ball retainer 6
Set 4 is in the hole of moving platen 5；Elastic collar 7 is stuck in the outer surface neck of guide pin bushing 4；The face of cylinder leading portion 3-1 of guide pillar 3 is in the second guide pin bushing
In 11 holes；The outer surface of second guide pin bushing 11 is in the hole of solid plate 10；Second screw 13 connects solid plate 10 and top clamping plate 12 solid
It is fixed.
Matched moulds process：As shown in Fig. 2 dynamic model part moves right, the leading portion 3-1 of guide pillar 3 first slips into the second guide pin bushing
In 11 holes, guiding and certain positioning action are played to the correct matched moulds of dynamic model part and cover half part, as dynamic model part continues
Move right, the rear sector hole 10-1 contacts of ball and solid plate 10 that 6 preceding sector hole of ball retainer is embedded in, ball retainer 6
The ball roll mode that preceding sector hole is embedded in advances to the right, untill dynamic model part reaches matched moulds state.Due to the back segment of guide pillar 3
There is 0.01~0.02 magnitude of interference between the hole 10-1 of ball, solid plate 10, improve mould bases dynamic model part and cover half part
Closing precision.
Although the utility model is disclosed as above with preferred embodiment, it is not limited to the utility model, any
Person skilled in the art, is not departing from spirit and scope of the present utility model, can all do various change and modification, therefore this
What the protection domain of utility model should be defined by claims is defined.
