Detailed Description
The invention is further described below with reference to the drawings and detailed description.
Example 1:
as shown in FIGS. 1 to 6, an all-plastic glass structure with anti-retention function comprises
The black edge layer 1 and the transparent layer 2 are connected with each other;
the black edge layer is provided with a through hole 3, one end of the through hole is an outer opening end, the other end of the through hole is an inner opening end, and the transparent layer seals the inner opening end;
the black layer is provided with a black first layer surface 11 and a black second layer surface 12, the black first layer surface is positioned between the transparent layer and the black second layer surface, the transparent layer is provided with a transparent first layer surface 21 and a transparent second layer surface 22, and the transparent first layer surface is positioned between the black layer surface and the transparent second layer surface;
the first layer surface of the black edge is attached to the first transparent layer surface, the first layer surface of the black edge is connected with the first transparent layer surface, any intersection line of any plane perpendicular to the first transparent layer surface and the outer edge 13 of the outer side of the black edge is an outer guide line, and an angle between the outer guide line and the first layer surface of the black edge is 10-60 degrees.
The angle between the outer drain line and the first layer of the black edge is 20 to 45 degrees.
The black edge layer is provided with a black edge arc surface 14, and the outer side edge of the black edge layer, the black edge arc surface and the black edge second layer surface are sequentially connected. The black edge arc surface can effectively reduce retention resistance, helps the shower coating liquid to flow from the outer edge of the black edge layer to the second layer surface of the black edge, and further improves the retention prevention effect.
The black border layer is made of PC material or ABS material.
The transparent layer is made of PC material.
The caliber of the inner opening end is smaller than that of the outer opening end, any intersection line of any plane perpendicular to the transparent first layer surface and the hole wall of the through hole is an inner guide line 31, and the angle between the inner guide line and the black first layer surface is 10-60 degrees. The inner guide line has the function similar to the outer guide line in principle, and can prevent great amount of shower liquid from accumulating near the junction of the hole wall and the transparent layer.
The angle between the drain line and the first layer surface of the black edge is 45 degrees. If the angle between the current-guiding line and the first layer surface of the black edge is too small, the thickness of the outer edge of the black edge layer is small, so that the injection molding is not facilitated, and poor injection molding is easily caused during injection molding; if the angle between the drainage line and the first layer surface of the black edge is too large, the drainage assisting effect on the shower coating liquid is not strong, the shower coating liquid is easy to stay, and 45 degrees are preferably selected in consideration of comprehensive consideration.
In the process of curtain coating, when the curtain coating liquid flows near the junction of the outer edge of the black edge layer and the transparent layer, the curtain coating liquid can not stay at the junction because a reasonable flow guide angle (the angle between the flow guide line and the first layer surface of the black edge layer is 45 degrees) is arranged between the outer edge of the black edge layer and the first layer surface of the black edge layer, and can quickly flow to the second layer surface of the black edge layer from the outer edge of the black edge layer through the arc surface of the black edge layer, so that the final forming effect of a product can be ensured.
Example 2:
on the basis of embodiment 1, as shown in fig. 7, the black edge layer comprises a body plate 2a and an external ring plate 2b, an inner hole is arranged on the external ring plate, the body plate is positioned in the inner hole, the through hole is arranged on the body plate, the external ring plate is clamped with the body plate, and the body plate is connected with the transparent layer.
The external annular plate is connected with the body plate in a clamping mode through a clamping structure, the clamping structure comprises a plurality of elastic protrusions 4 arranged on the wall of the inner hole and a plurality of clamping holes arranged on the outer side edge of the body plate, the elastic protrusions are in one-to-one correspondence with the clamping holes, and the elastic protrusions are clamped in the corresponding clamping holes.
When the shower coating is performed, the quality problem is most likely to occur, namely, the boundary part between the outer edge of the black edge layer and the transparent layer is near, and the outer edge of the black edge layer is arranged on the external annular plate, so that the angle between the drain line and the first layer surface of the black edge layer can be changed to be 45 degrees by adopting different external annular plates according to different shower coating requirements. In addition, when the surface quality of the outer edge of the black edge layer is not up to the requirement or has flaws, the external annular plate can be detached for repairing operations such as polishing, and then the external annular plate is replaced, if the external annular plate cannot be repaired, the external annular plate can be directly replaced.
