Description
Technical field
The present invention relates to a kind of technical field of mold, particularly relate to a kind of protection thick stick injection mold.
Background technology
Injection moulding is a kind of method of industrial products production moulding.Product uses rubber injection mold and plastics injection moulding usually.Injection moulding also can divide injection mould platen press and casting die.Injection (mo(u)lding) machine (being called for short injector or injection machine) utilizes mould for plastics to make the main former of the plastic products of various shape thermoplastic or thermosetting material, and injection moulding is realized by injection machine and mould.
Injection molding machine (injection machine) has two basic elements of character: for melting and injection device and the mold closing mechanism of plastics being sent into mould.The effect of mold closing mechanism is: make mould to sustain in injection pressure situation closed; Goods are taken out injection device by its melting before plastics inject mould, then melt is injected mould by controlled pressure and speed.The injection device adopted now has two kinds of designs: screw preplasticator or dual-range unit, and reciprocating screw.Screw preplasticator utilizes preplasticizing screw rod (first order) molten plastic to be injected feed rod (second level) again.The advantage of screw rod preplasticator is fused mass constant mass, high pressure and high speed, and accurate injection volume controls (utilizing the mechanical thrust brake at piston stroke two ends).These strong points are required for transparent, thin-gage goods and high throughput rate.Its shortcoming comprises the uneven time of staying (causing material degradation), higher cost of equipment and maintenance cost.The most frequently used reciprocating screw injection device does not need plunger by plastics melting and injects.The type of injection machine has: vertical, horizontal, all electric, but no matter that injection machine, and its basic function has two: heating of plastic, makes it reach molten state; High pressure is applied to molten plastic, makes it penetrate and be full of mold cavity.
Blank is made to become the instrument of the product having given shape and size under external force.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, the two partable.Take out product time separately, make blank inject mold cavity when closing up and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.
The existing injection mold structure for the processing of protection thick stick is complicated at present, and inconvenient operation, product molding effect is general.
