Description
Technical field
The utility model belongs to technical field of mold, and in particular to a kind of mold external member preparing magnesium alloy health cup.
Background technology
Water is the source of human life.With the improvement of living standards, people are seeking a kind of more healthy water source.
Most of health-care cup sold currently on the market passes through light, electricity, magnetic, iron absorption or catalytic action so that light water light electrolysis becomes
At the healthy water with alkalescent, subset, negative potential, rich oxygen content.However, this kind of health-care cup needs specific material
Matter forms, and structure is more complex, bulky, it is difficult to carry；And it is expensive, it cannot be made by vast ruck
With.
Magnesium alloy is as most light structural metallic materials, excellent processability low with density, high specific strength and specific stiffness
And the advantages that easily recycling, it is known as " 21 century green engineering material ".With energy saving with environmentally friendly today being the theme, magnesium alloy
Development has been included in the great research project of country, therefore magnesium alloy product has the stronger market competitiveness.In addition, magnesium elements conduct
One of indispensable element of human body has good biocompatibility, has had in a large amount of magnesium-alloy material applying clinical medicine.Phase
Than in aluminium alloy and steel, allergy toxic reaction will not be caused.Meanwhile magnesium elements are distributed more widely in the earth's crust, other are replaced with it
Metal material, the problems such as greatly alleviating resource scarcity and environmental pollution.Therefore, from the market demand and manufacturing cost, also gently
The features such as quantization, is not difficult to find out, is had a good application prospect using magnesium alloy manufacture health-care cup.
Currently, the production technology of metal cup is divided into integrated molding and non-integral molding.It is integrally formed and is mainly squeezed with anti-
Pressing formation, it is a kind of metal-pressed machine technique of no cutting, is widely used in the production of thin-walled cup shell or pipe fitting,
The advantages of such technique is the cup type idiosome that squeezes out directly with Packed bottom, but during backward extrusion, due to
It needs to reserve certain space between punch-pin and cavity plate, in order to form wall of cup；And the presence in space makes punch-pin be difficult alignment base
Expect block center, the health-care cup idiosome wall of cup finally squeezed out is in uneven thickness, and rejection rate is higher.Rather than it is then first to be integrally formed
Bottomless idiosome is processed by mechanical processing tools variously-shaped, then recycles seamless welding technology by idiosome and bottom of a cup
It connects, the process-intensive more demanding to welding technique of such technique, and yield rate is low, high labor cost.
