Detailed Description
The invention is further described with reference to the following figures and detailed description.
Example 1:
as shown in fig. 1 to 6, the automatic liquid-blocking plastic glass comprises
The black edge layer 1 and the transparent layer 2 are connected with each other;
the black edge layer is provided with a coating blocking rib 3 and is positioned between the coating blocking rib and the transparent layer;
the black edge layer is provided with a through hole 4, 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.
When the front surface is coated in a curtain mode, after part of the coating liquid flows to the back surface, the coating liquid flows down along the back surface, due to the existence of the coating blocking ribs, the coating liquid can be blocked by the coating blocking ribs and directly falls down, and the coating liquid cannot reach the back surface appearance surface (on the transparent layer back surface appearance surface), so that flow marks generated on the appearance after heat curing can be effectively prevented, and the final surface quality of a product is guaranteed.
The black border layer is made of a PC material or an ABS material.
The transparent layer is made of a PC material.
The curtain coating blocking rib and the black edge layer are of an integrally formed structure.
The black edge layer is provided with a black edge first layer surface 11 and a black edge second layer surface 12, the black edge first layer surface is positioned between the transparent layer and the black edge 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 edge layer and the transparent second layer surface; the first aspect of black limit pastes with transparent first aspect mutually, and the first aspect of black limit is connected with transparent first aspect, and the plane of the transparent first aspect of arbitrary perpendicular to is outer water conservancy diversion line with the arbitrary line of intersecting of black limit outside edge 13, and the angle between outer water conservancy diversion line and the first aspect of black limit is 45 degrees. If the angle between the flow guide 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 injection molding is not facilitated, and poor injection molding is easily caused during injection molding; if the angle between the diversion line and the first layer surface of the black edge is too large, the auxiliary drainage effect on the coating liquid is not strong, the coating liquid is easy to be retained, and the angle is preferably 45 degrees in comprehensive consideration. In the curtain coating process, when the curtain coating liquid flows through the outer side edge of the black edge layer and the vicinity of the junction of the transparent layer, as a reasonable flow guide angle is formed between the outer side edge of the black edge layer and the first layer surface of the black edge (the angle between the flow guide line and the first layer surface of the black edge is 45 degrees), the curtain coating liquid cannot be retained at the position, and can flow from the outer side edge of the black edge layer to the second layer surface of the black edge through the arc surface of the black edge, so that the final forming effect of a product can be ensured.
The curtain coating method is suitable for the automatic liquid blocking type plastic glass in the embodiment, the curtain coating blocking rib comprises a blocking section, the plastic glass to be curtain coated is fixed before curtain coating, and the blocking section is located above the through hole after the plastic glass to be curtain coated is fixed. After the plastic glass to be coated is fixed, the blocking section is horizontally arranged. The blocking section is arranged above the through holes and horizontally, so that the curtain coating liquid can be effectively prevented from being left along the back of the product and reaching the back appearance surface (on the back appearance surface of the transparent layer), thereby effectively preventing the appearance from generating flow marks after heat curing and ensuring the surface quality of the transparent layer.
Example 2:
on the basis of embodiment 1, as shown in fig. 7, the black edge layer includes a body plate 2a and an external ring plate 2b, an inner hole is formed on the external ring plate, the body plate is located in the inner hole, the through hole is formed on the body plate, the external ring plate and the body plate are clamped, and the body plate is connected with the transparent layer. Connect through joint structure joint between ring plate and the body board, the joint structure includes a plurality of elastic bulge 5 and a plurality of card holes of setting on the body board outside edge of setting on the hole pore wall, elastic bulge and card hole one-to-one, and the elastic bulge card is in the card hole that corresponds.
When drenching and scribbling, the quality problem appears in the most likely near black border layer outer fringe and stratum lucidum juncture, and black border layer outer fringe just sets up on the outer ring board that connects, consequently, drenches the demand to the difference, can adopt different outer ring boards to change the angle between water conservancy diversion line and the first floor of black border and be 45 degrees. In addition, when the outer lateral margin surface quality of black border layer does not reach the requirement or when having the flaw, can pull down external ring board and carry out repair operations such as polishing, then the external ring board of reloading, if unable when restoreing, can also directly change external ring board.
