Abstract

The invention discloses an overall-position model-opening injection mould which is suitable for producing an injection product which is high in precision and complex in three-dimensional shape. The injection mould mainly comprises a cross-shaped slide groove mould seat. At least two sets of corresponding slide block moulds are arranged in a slide groove of the cross-shaped slide groove mould seat, the whole mould set is fixed on an operation bench surface of the device by a cover plate and meanwhile a sealed slide groove is formed. Each sets of the slide block moulds is connected to corresponding driving mechanisms on the device and slides reciprocatingly and linearly in the slide groove by means of the linkage by the driving mechanism to complete functions of closing the mould and opening the mould. The mould has a breakthrough multiple slide block structure, can be opened in overall positions, is free of limit in conventional moulds, can produce the injection product which is complex in structure and is high in precision requirement, and can ensure stability of product quality while a cost is reduced and productivity is greatly enhanced.

Description

Omnibearing mold opening injection mold

Technical field

The present invention relates to a kind of injection mold, particularly a kind of can rapid mould opening-closing, be suitable for the Omnibearing mold opening injection mold of production high precision, baroque injection-moulded plastic part.

Background technology

Plastics are widely used a kind of new structural materials in each department of world national economy and people's sphere of life, along with the fast development of digitizing technique and electronic information technology, the demand of injection-moulded plastic part is got more and more, these parts structurally become more complicated and volume constantly to miniaturization, it is microminiaturized, complicated, thin-walled property and precision degree more and more higher, meanwhile, accelerate along with electronic product is regenerated, the demand of the unit interval of its parts is huge.

Traditional injection mold, be made up of a cover half and a dynamic model, dynamic model is reciprocating along guide pillar under the driving of oil cylinder, complete the function of Guan Mo and die sinking, only have a die sinking direction, cause Design of Dies possibility few, mould volume is comparatively large, manufacturing cost is high, speed of production produces burr slowly, easily, has been difficult to the needs meeting even not competent market development in microminiaturized, complicated, thin-walled property and high precision.

Summary of the invention

The object of the invention is the deficiency overcoming above-mentioned technology, adopt the innovative design thought of multi-faceted die sinking, by the single die sinking direction of traditional injection moulding mould, be improved to and adopt accurate cross guiding die holder to realize multiple directions die sinking, have developed Omnibearing mold opening injection mold, mold parting surface selects elasticity large, the restriction of beyond tradition mould, achieve complicated multiaspect 3D shape part and the manufacture of high-precision requirement part, reduce the manufacturing cost of mould.

The technical solution adopted for the present invention to solve the technical problems is: a kind of Omnibearing mold opening injection mold, includes ' ten ' word chute die holder, slider mould, die cap and demoulding block; ' ten ' word chute die holder is arranged on the work top of equipment by four guide pillars on equipment, in the chute of slider mould is placed in ' ten ' word chute type matrix seat, whole set of die to be locked and forms closed chute, and be fixed on the work top of equipment by cover plate; Often organize slider mould in chute, do reciprocating linear slip, complete the function of Guan Mo and die sinking; Demoulding block is fixed on ' ten ' word chute die holder, is separated with mould for making part.

Further, described ' ten ' word chute die holder, offer ' ten ' word and split four road chutes in length and breadth, four guide holes, ' ten ' word chute die holder is arranged on the work top of equipment by four guide pillars on cooperating equipment; The hole of cross chute die holder middle part is for being coupled to the cast gate of the slider mould be carried in ' ten ' word chute die holder by the nozzle of injection device.

Further, described slider mould is made up of slide block and module, and module is for the formation of part partly molding cavity, and slide block and mould are located by positioning key and fixed by screw and form one group of overall slider mould; Slider tail has pin-and-hole, is connected, has water channel in module by connecting pin with the drive unit of equipment, for controlling mold temperature.

Further, described die cap, has four through holes, four guide pillars on cooperating equipment; The cross recess of middle part, for meeting slider mould motion requisite space and part taking-up requisite space.

Further, described de-inside modules is provided with pore and nozzle opening, is respectively used to the part deviate to be blown into material-receiving device, and sprays mould oil to mold cavity in need.

During use, each slider mould of Omnibearing mold opening injection mold is under drive unit interlock, by the pass mould orderly close-down mould of setting, injected plastics material by nozzle injection in the die cavity of mould, and after pressurize, cooling, solidifying and setting, by the die sinking order opening mold of setting, by the demoulding and inflatable body, goods are sent into charging basket, start next circulation, technique is simple, stable, efficient simultaneously.

The version of this Omnibearing mold opening injection mold, can install, change mould and can select the multiple demoulding and part to take out mode easily, according to the complexity of part, Design of Dies can be become two mould to four mould external reinforcement cover half and tiltedly loose core, all kinds of parts of the multi-face solid moulding from simple to complexity can be produced.

The invention has the beneficial effects as follows: Omnibearing mold opening injection mold die joint selects elasticity large, the restriction of beyond tradition mould, can high, the minimized injection-moulded plastic part of complex structure, burr of high efficiency production precision, effective reduction mould and cost of goods manufactured, make operation simpler, safe, efficient, meet the market demands that injection-moulded plastic part structure becomes increasingly complex, required precision is more and more higher, cost pressure is increasing.
