Description
Technical field
The utility model relates to reflective membrane and makes mechanical field, especially a kind of reflective membrane cold press.
Background technology
Known, reflective membrane is a reflex reflection principle of utilizing optics, its reflector element can be divided into two types of glass microballoon and microprisms, reflective membrane with microprism reflector element is owing to its remarkable reflex reflection performance, the fields such as different kinds of roads traffic safety facilities, sign board and vehicle passive security protector that are applied to more and more widely.Its principle is to form equally distributed microprism array structure on the plastic-based film surface, so-called microprism array structure is meant by three structures that plane perpendicular to each other constituted each other, can carry out total internal reflection to incident light, thereby improve reflection of incident light efficient greatly from front surface.Micro-prism type reflective membrane production method generally by mould with plastic foil hot pressing after cooling forming, mould is generally two metal forms, wherein a metal form surface distributed has the concave units that forms microprism array structure, plastic foil is positioned between two templates, putting into hot press carries out heat and melts compacting, put into cold press again and carry out cold moudling, and there are problems such as complex structure, operation inconvenience in existing cold press.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of reflective membrane cold press simple in structure, easy to use is provided.
The purpose of this utility model realizes by following technical solution:
A kind of reflective membrane cold press, it is characterized in that: comprise frame, be relatively arranged on the upper and lower pressing plate on the frame, drive unit and the circulating water supply system that the relative the opposing party of a side in the upper and lower pressing plate of driving moves up and down, described upper and lower pressing plate is provided with the inner chamber of sealing, and be provided with entery and delivery port with described intracavity inter-connection, described water inlet is communicated with the water side of described circulating water supply system, and described delivery port is communicated with the water inlet end of described circulating water supply system.
Further, described lower platen is fixedly set on the described frame, and described top board can be arranged on the frame by described relatively lower platen up or down.
Further, described drive unit is an oil cylinder.
Further, described upper and lower pressing plate all adopts the metal material of high-termal conductivity to make.
Further, described circulating water supply system, comprise water supply line, water-storing device and be arranged at water supply line and water-storing device between water pump.
The utlity model has following beneficial effect:
During work, the metal form that hot-pressing processing is crossed is positioned between the upper and lower pressing plate colds pressing, upper and lower pressing plate all adopts the metal material of high-termal conductivity to make and is formed with inner chamber, cooperate circulating water supply system can make in the inner chamber of upper and lower pressing plate and form the cooling water that flows, thereby the heat of taking away metal form makes the plastic foil cooling between two metal forms form reflective membrane, and overall structure of the present utility model is simple, easy to operate and cost is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structural representation of the present utility model, is in the state of colding pressing.
The specific embodiment
Shown in seeing figures.1.and.2, a kind of reflective membrane cold press comprises frame, top board 6, lower platen 10, oil cylinder 8 and circulating water supply system.
Frame is by base 1, be arranged at the column 2 on the base 1, and the last mount pad 7 that is arranged on the column 2 is formed, the cylinder body of oil cylinder 8 is fixedly set on the last mount pad 7 of frame, its piston rod extends vertically downward and connects top board 6, can drive top board 6 vertically moves up and down, lower platen 10 is arranged on the base 1 of frame with top board 6 relative fixed, on, lower platen 6,10 all are formed with the inner chamber 11 of sealing, and be provided with and advancing that inner chamber 11 is connected, delivery port 9,5, advance, delivery port 9,5 are relatively arranged on the both sides of pressing plate, wherein, water inlet 9 is communicated with the water side of circulating water supply system, delivery port 5 is communicated with the water inlet end of circulating water supply system, the circulation of formation water-cooled, wherein circulating water supply system is by water supply line 4, the water-storing device (not shown), and the water pump (not shown) that is arranged between water supply line and the water-storing device is formed.
Concrete working method is: start circulating water supply system and form the water-cooled circulation, to be positioned over through the mould 3 that hot-pressing processing is crossed on the lower platen 10, control oil cylinder 8 drives top board 6 and presses down, the press time control well so that be in the plastic foil cooling forming of the melting state in the mould 3, control oil cylinder 8 then and drive top board 6 liftings, mold removal 3 takes out the reflective membrane of moulding from mould 3, and plastic foil to be processed is positioned between the metal form of mould, enters next circulation.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
