Description
Technical field
This utility model relates to injection mold field, specifically a kind of injection mold being applicable to complicated plastic and release method thereof.
Background technology
Existing injection mold, including upper mould (also referred to as male model) and counterdie (also referred to as master mold), counterdie has core corresponding with plastic inner surface configuration, and counterdie has die cavity corresponding with plastic external surface shape.After upper and lower mould matched moulds, core coordinates with die cavity, pours into a mould injection moulding liquid in space between, after the cooling of injection moulding liquid, mould in unlatching, takes out plastic after the demoulding.Plastic for structure relative complex, it will usually slide block is set on upper mould, after injection moulding completes and cools down, first sliding slider, the then demoulding again.But, for the plastic that structure is increasingly complex, as depth dimensions is very big, and having the local isostructural plastic of hole slot concurrently, the mould of existing structure just cannot realize a Shooting Technique.
Plastic as depicted in figs. 1 and 2, this plastic is a chair body, including seat support 10, handrail 11, arm supports 16 and the chair back 12.Described handrail 11, arm supports 16 and the chair back 12 shape in curved surface, the both sides flare of seat support 10, and be additionally provided with the rear foot joint pin 17 of a pair fixing rear chair foot and the forward foot in a step joint pin 13 of a pair fixing forward foot in a step in the corner of seat support 10, described rear foot joint pin 17 is connected with arm supports 16.It is provided with socket 14 in each joint pin 13 and 17, is additionally provided with pair of screws fixing hole 15 in the inner side of described socket 14.Chair foot is inserted in socket 14, and just chair foot and chair body can be fixed at screw fixed hole 15 place screw-in screw.Owing to the degree of depth of chair body is relatively big, the curved-surface structure of many places is arranged at top, and both sides have seat support 10 to be inclined-plane, joint pin 13 and 17 is outward-dipping, and connecting cylinder 13 and 17 has circular socket 10 and screw fixed hole 15, for the plastic of this labyrinth, traditional dies cannot complete the demoulding.
Summary of the invention
The problems referred to above being prior art and existing to be solved in the utility model, it is desirable to provide a kind of injection mold being applicable to complicated plastic.
For solving the problems referred to above, this utility model is by the following technical solutions: a kind of injection mold being applicable to complicated plastic, including upper die and lower die, described counterdie includes die cavity template, it is characterised in that described die cavity template is provided with rear slider, side slide, tiltedly looses core and slanted kicking block；Further, the upper surface of described slanted kicking block is corresponding with the bottom surface of plastic, the side of slanted kicking block and described relative configuration of tiltedly loosing core, and is additionally provided with projection in the side of slanted kicking block；Described tiltedly loose core, slanted kicking block and each slide block be by corresponding hydraulic oil cylinder driving.
A kind of injection mold being applicable to complicated plastic of the present utility model, being provided with rear slider, slide block in the die cavity of counterdie, tiltedly loose core and the movable part such as slanted kicking block, these movable parts can make backward under respective hydraulic oil cylinder driving, to both sides, move obliquely or obliquely.These movable parts are arranged on and on the position of direct demold, after die sinking, first movable part cannot be departed from from plastic, then carry out the demoulding again.Wherein, tiltedly loosing core corresponding to the oblique slotted eye on plastic, the projection on slanted kicking block is corresponding to the horizontal slotted eye on plastic.Complexity according to processed plastic component structure, side slide can adopt one, two or more.Also dependent on the symmetric case of processed plastic, side slide adopts a pair, two pairs or multipair.
Adopt injection mold of the present utility model to add formula plastic, after injection moulding, carry out stripping operation according to the following steps:
1), mould die sinking；
2), rear slider slide backward under hydraulic oil cylinder driving, side slide slides laterally under hydraulic oil cylinder driving；
3), tiltedly loose core and oliquely downward move under hydraulic oil cylinder driving；
4), slanted kicking block move obliquely upward under hydraulic oil cylinder driving, the top of slanted kicking block is drawn close to center, and the projection on slanted kicking block departs from from plastic, and the top of slanted kicking block ejects the die cavity of counterdie plastic；
5) demoulding, takes out plastic.
This utility model to the complicated shape plastic integral injection moulding especially with the hole slot structure of local, can improve production efficiency, reduce technological process, reduce cost of manufacture, and be conducive to the improvement of product design and structure.
As improvement of the present utility model, described side slide includes a pair first side slides and a pair second side slides.This structure, is particularly suitable for the plastic of symmetrical shape.
As further improvement of the utility model, described tiltedly looses core and slanted kicking block respectively 4, and one_to_one corresponding.This structure, makes this utility model be particularly well-suited to the injection molding with chair foot connection socket and the chair body of chair foot screw fixed hole.
Further improving as of the present utility model, sprue gate is arranged on the bottom of counterdie, and the sprue gate of such product, just on bottom surface, is not exposed, thus the aesthetics of product is high.
Further improve as of the present utility model, in upper mould and/or counterdie, be additionally provided with cooling water pipeline.In casting process by water-cooled but, accelerate the cooling of injection moulding liquid, further high efficiency can be carried, and guarantee that mould is not by high temperature failure.
