Abstract
A metal die for preparing reflective right-angle prisms belongs to the processing technical field of reflective material, and mainly comprises a die substrate (1), regular four-side cones (2) evenly distributed on the die substrate (1), wedgy grooves (3) arranged at the bottom of the regular four-side cone (2) and distributed evenly like a square, etc. the conicity of each side of the regular four-side cone (2) is 45 DEG; with reasonable design of the whole structure and simple processing, the metal die can be used for processing in a numerical control machine with certain precision; the metal die of the invention can be used for engraving reflective corns distributed evenly on the surface of the thermoplastic plastics through heating and pressurizing or other technics.
Description
Technical field
The present invention relates to a kind of metal mould for preparing reflecting right angle prism, belong to the processing technique field of reflectorized material.
Background technology
Ray Of Light shines the surface of reflecting material, and the light of its reflection can return light source direction substantially, and this reflection is called retroreflecting and is commonly called as reflective.
Retroreflecting generally can be realized by dual mode: 1, utilize the facetted mirrors of the right-angle prism of material surface; 2, utilize the glass microballoon of the certain refractive index of material surface.What the present invention relates to is the reflective mode of right-angle prism polyhedron (being reflective cone again), and at the right-angle prism that material surface is evenly distributed, each right-angle prism just can constitute a catoptric system.
Making right-angle prism needs a kind of metal die, utilizes this metal die, under conditions such as heating pressurization, produces the reflective conical surface on the thermoplastic surface, and promptly the polyhedral catoptric system of right-angle prism has good retroreflecting effect.
Traditional preparation method is that each cone is cast separately, and difficulty of processing is big, and difference is obvious between the cone, and whole surface is inhomogeneous, and the accuracy of manufacture is inaccessible.The reflectorized material of making by this mould heat pressure causes the surface inhomogeneous easily, and reflecting effect is poor.03200796.5 it is Ni electricity casting that a kind of advanced processing method is provided, ratio of precision is higher, but Ni electroforming part also duplicates on hexahedral mother matrix mould, the production process complexity, domestic do not have a relevant technological means, so the making difficult problem of high accuracy template is also unresolved.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in designly, can satisfy the metal mould for preparing reflecting right angle prism of the reflective requirement of high accuracy.
The present invention is a metal mould for preparing reflecting right angle prism, it is characterized in that comprising die substrate, places equally distributed positive four sides cone on the die substrate, the wedge-shaped impression that places positive four sides cone base quadrate to distribute.
The material of described metal die substrate can be copper or aluminium, stainless steel, alloy etc., the metal material of all available lathe drill bit flutings.
The tapering of each face of described positive four sides cone is 45 °.
The present invention is reasonable in design, processes simple and conveniently, just can machine on the Digit Control Machine Tool of certain precision.Adopt metal die of the present invention,, can cut out equally distributed reflective cone on the thermoplastic surface by technologies such as heating pressurizations.

The specific embodiment
The present invention places equally distributed positive four sides cone 2 on the die substrate 1 mainly by die substrate 1, wedge-shaped impression 3 formations such as grade that place cone 2 bottom quadrates in positive four sides to distribute.The material of metal die substrate 1 is copper or aluminium, stainless steel, alloy etc., the metal material of all available lathe drill bits flutings, and the tapering of each face of positive four sides cone 2 is 45 °.
Embodiment 1:
1, metal material is prepared: get the square copper coin of a block length, thickness is 5 millimeters, and any surface finish becomes minute surface, 20 centimetres of length, 16 centimetres of width;
2, slotting drill bit is prepared: get the drill bit that vertical cross-section is down equilateral perpendicular type, drill bit hardness is enough slotted on copper coin;
3, fluting: slot at the smooth surface of copper coin with the fluting lathe: 1 opens article one groove along its length, and the degree of depth is 1 millimeter, and groove width is 2 millimeters; 2 along its length, and apart from 2 millimeters of article one groove centers, promptly 2 millimeters places of groove center spacing open the second groove, and the degree of depth is 1 millimeter, and the second groove width is 2 millimeters, so opens the closely uniform parallel slot of a lot of bars at length direction; 3 at width, and promptly the vertical direction of parallel slot is opened same groove with same drill bit, and the degree of depth is 1 millimeter, and width is 2 millimeters, and the groove center spacing is 2 millimeters, opens the groove of the closely uniform width of a lot of bars;
4, polishing: remove metal fillings, reflective cone phantom plate completes.
Embodiment 2:
1, metal material is prepared: get the square aluminium sheet of a block length, thickness is 5 millimeters, and any surface finish becomes minute surface, 20 centimetres of length, 16 centimetres of width;
2, slotting drill bit is prepared: get the drill bit that vertical cross-section is down equilateral perpendicular type, drill bit hardness is enough slotted on aluminium sheet;
3, fluting: slot at the smooth surface of aluminium sheet with the fluting lathe: 1 slots along its length, and the degree of depth is 2 millimeters, and groove width is 4 millimeters; 2 along its length, and apart from 4 millimeters of article one groove centers, promptly 4 millimeters places of groove center spacing open the second groove, and the degree of depth is 2 millimeters, and the second groove width is 4 millimeters.So open the closely uniform parallel slot of a lot of bars at length direction; 3 at width, and promptly the vertical direction of parallel slot is opened same groove with same drill bit, and the degree of depth is 2 millimeters, and width is 4 millimeters, and the groove center spacing is 4 millimeters, opens the groove of the closely uniform width of a lot of bars;
4, polishing: remove metal fillings, reflective cone phantom plate completes.
Adopt the metal die of the foregoing description preparation,, can cut out equally distributed reflective cone on the thermoplastic surface by technologies such as heating pressurizations.
