Description

The decorative pattern structure of hollow molding surface

The utility model relates to hollow molded body, refers in particular to the decorative pattern structure of a kind of hollow molding surface.

Hollow molded body commonly used comprises the tool box, the instrument link plate, packing box, suitcase etc., its construction features are the structure of tool air blanketing in the middle of being made up of ground floor panel and second layer panel, surface at the ground floor panel forms the mere formality word, trade mark, the decorative pattern of pattern etc., form the depression of given shape at second layer panel, put the instrument or the article of given shape for buckle, the method for making of this hollow molded body and surface detail thereof is for to make the mould with surface detail and given shape depression earlier, sebific duct shape plastics placed to be blow molded in the mould again to have the hollow molded body that surface detail and second layer panel are provided with the given shape depression on the ground floor panel.Its major defect is: because surface detail and hollow molded body are the integrally blow formation structure, so making different surface details, desire must offer mould in addition, cause processing cost relatively more expensive, and surface detail can only be identical color and quality with hollow molded body, make the product dullness, can not make well-rounded product.

The purpose of this utility model is to provide the decorative pattern structure of a kind of hollow molding surface, overcomes the drawback of prior art, reaches the purpose that reduces manufacturing cost and be convenient to process colorful colourful surface detail.

The purpose of this utility model is achieved in that the decorative pattern structure of a kind of hollow molding surface, comprise that hollow molded body is provided with the suitable space of ground floor panel and the formation of second layer panel, the surface of this ground floor panel is provided with decorative pattern, form depression on this second layer panel, it is characterized in that the periphery of this decorative pattern forms the edge of grabbing of suitable height, this grabs edge makes the back of this decorative pattern form the interval of depression, this edge of grabbing edge is suitably apart from the air drain of escaping that is respectively equipped with depression, this decorative pattern takes shape in the surface of this ground floor panel, this is grabbed being coated by this ground floor panel by the lower part of edge and clamps, it then is exposed to the surface of this ground floor panel by top, in the ground floor panel of locating between the depressed area of this decorative pattern back is absorbed between this depressed area; This decorative pattern is made up of most decorative patterns unit; Enclose by moulding around this decorative pattern or each the decorative pattern unit; This decorative pattern or each decorative pattern unit are respectively equipped with rib and are connected with this moulding, and each rib is positioned at the lowest part of this decorative pattern or each decorative pattern unit; This edge of grabbing edge is suitably apart from the air drain of escaping that is respectively equipped with depression; The edge of this moulding is provided with the air drain of escaping of depression every suitable distance; The periphery of this moulding forms the inclined side of suitable angle, and its incline direction is for to tilt to upper face center from the bottom; The outer peripheral edges of grabbing edge of this decorative pattern or each decorative pattern unit are provided with the inclined side of suitable angle, and its incline direction is for to tilt to upper face center from the bottom of decorative pattern or each decorative pattern unit; Being coated by the ground floor panel by the lower part of edge and moulding of grabbing of this decorative pattern or each decorative pattern unit clamped, and it then is exposed to the upper surface of this ground floor panel by top; This escapes the moulding at air drain place and grabs edge to still have part to be coated clamping by the ground floor panel, and this escapes the outer surface that air drain does not expose the ground floor panel; Grab edge and the moulding of this decorative pattern or decorative pattern unit are coated clamping place by the ground floor panel and form shaft of rib; This ground floor panel is in even curface; This decorative pattern comprises literal, trade mark or pattern.

Major advantage of the present utility model is because decorative pattern of the present utility model is that reshaping makes simple structure in the surface of the ground floor panel of hollow molded body after the first moulding, low processing cost, and the well-rounded surface detail of convenient variation; Grab edge and the moulding of decorative pattern are formed shaft of rib by coating clamping place of the ground floor panel of hollow molded body, have greatly increased the support strength of the structural strength and the opposing external force of ground floor panel.

Further specify below in conjunction with preferred embodiment and accompanying drawing.
