Description
Technical field
The present invention relates to a kind of aluminium alloy plastics suction moulds more particularly to one kind quickly to heat and soften plastic sheet
The new-type aluminium alloy plastics suction mould of processing, belongs to plastic suction forming apparatus accessory technical field.
Background technology
Plastic suction forming apparatus is called thermoplastic shaping machine, and operation principle is：The pull of vacuum generated using vacuum pump will heat
The thermoplastic plastics sheet material such as PVC, PET, PETG, APTT, PP, PE, PS after softening is made variously-shaped by mold plastic uptake
Vacuum (-tight) housing or be attached in the surface of variously-shaped product.Plastic uptake technique according to the thickness of sheet material can be divided into thin slice plastic uptake and
Sheet plastic uptake.
Used mold is known as plastics suction mould on plastic suction forming apparatus, it is after open and flat plastic sheet heating is softened,
Using vacuum suction in the surface of plastics suction mould, it is molded plastic packing product is made after cooling.Existing plastics suction mould is most
Whole heating is carried out to lower die using the electric calorifie installation built in lower die, to realize that the heating and softening to plastic sheet is handled.It is above-mentioned
Although method realizes the heating material sofening treatment to plastic sheet, but softening process is firstly the need of carrying out lower die whole heating,
Intermediate link is increased, while is influenced by lower die heat conductivility, reduces the softening efficiency of plastic sheet to a certain extent.

The present invention is a kind of new-type aluminium alloy plastics suction mould, which includes upper die and lower die, is formed and inhaled after molding
Mold cavity, bleed-off passage built in the upper mold and annular water-cooling structure, warm wind channel design, described built in the lower die
The external warm wind air supply plant of lower die, the warm wind passage end are plastic uptake die cavity, and the other end is warm wind air supply plant.
In a preferred embodiment of the present invention, the warm wind channel is uniformly distributed in a ring from top to bottom, and quantity is about 5-7
A, diameter is about 5-6cm.
In a preferred embodiment of the present invention, the extension inner ring of the warm wind channel processes internal thread structure.
In a preferred embodiment of the present invention, the warm wind air supply plant is by wind turbine, heating element, radiator, air-supply
Pipeline and control assembly and interlock circuit composition.
In a preferred embodiment of the present invention, the air supply duct is connected with warm wind beneath galleries, and the two is pipe screw thread
Connection.
In a preferred embodiment of the present invention, the heating element uses PTC ceramics heater, highest heating temp
Up to 1000 DEG C, the heating-up time is 20 seconds.
In a preferred embodiment of the present invention, the power of the wind turbine is 1.5w, and wind speed is adjustable.
Present invention is disclosed a kind of new-type aluminium alloy plastics suction moulds, and the plastics suction mould is reasonable in design, and effect is unique,
External high-temperature hot-air can be introduced directly into plastic uptake die cavity by the warm wind channel design opened up in lower die, and directly plastic sheet is carried out
Heating and softening is handled, and the heating of plastic sheet is rapid, heated to be more uniformly distributed, and effectively raises the softening efficiency of plastic sheet,
And the plastic uptake quality of plastic sheet is improved to a certain extent.
