Description
Technical field
The present invention relates to injection machine mould fields, more specifically to a kind of note with temperature control die cavity deformation function
Molding machine mold.
Background technique
Injection mold is a kind of tool for producing plasthetics, is also to confer to plasthetics complete structure and accurate dimension
Tool.Injection mold is made of dynamic model and cover half two parts, and dynamic model is mounted on the moving die plate of injection (mo(u)lding) machine, cover half installation
On the fixed form of injection (mo(u)lding) machine, dynamic model and cover half closure constitute running gate system and type chamber when injection moulding, and when die sinking is dynamic
Mould and cover half separation are to take out plastic products.Product is typically left in dynamic model when modulus, because there is demoulding in the fixed plate of dynamic model
Mechanism.Mold is mainly made of running gate system, thermoregulating system, forming part and constitutional detail.Wherein running gate system and molding zero
Part be with the direct contact portion of plastics, and change with plastics and product, be it is most complicated in mold, variation is maximum, it is desirable that processing
Finish and the highest part of precision.
Cover half is also known as master mold, upper mold, and because cover half part is usually all the appearance of product, it is interior that mode shape is generally mostly
Recessed, so image is referred to as master mold；Dynamic model is also known as male model, lower die, because dynamic model part is usually all the inside face of product,
Mode shape generally more to be outwardly protruded, so the dynamic model of image is referred to as male model.
Marmem (shape memory alloys, SMA) is by thermoelasticity and martensitic traoformation and its inversion
And the material being made of two or more metallic elements with shape memory effect (shape memory effect, SME).
Marmem is the material that shape-memory properties are best in current shape-memory material.Why marmem has
Recoverable force ability is because of the thermoelastic martensitic transformation that material internal occurs in deformation process.Have in marmem
There are two types of phases: high-temperature-phase austenite phase, low-temperature phase martensitic phase.
Marmem can be divided into three kinds according to shape memory effect again: one-way memory effect: marmem exists
Deformed at lower temperature, the shape after heating before recoverable deformation, this during heating existing shape memory it is existing
As referred to as one-way memory effect；Double-pass memory effect.Restore high-temperature-phase shape when certain alloys heat, can restore low again when cooling
Warm phase shape；Whole memory effect.Restore high-temperature-phase shape when heating, it is identical and be orientated opposite low temperature to become shape when cooling
Phase shape.
The type chamber that the dynamic model and cover half of existing injection machine mould are formed morphologically has uniqueness, so a kind of mold is only
It can be molded by a kind of product of geomery, make material and mold that there is minimum utilization rate；When existing product is moulded in demoulding,
Product is usually to stay on dynamic model, is then ejected product by demoulding mechanism, but since liftout dynamics is improper, can stay on product
Lower mark, is greatly reduced the quality of injecting products, or even causes the loss in material and Shooting Technique.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide one kind to have the function of the deformation of temperature control die cavity
