Abstract

A die for manufacturing floor tile with arc corners is composed of punching knives with cutting edge, and a bottom plate with arc structure for connecting said punching knives. A method for manufacturing the floor tile with said die includes such steps as hot press for shaping the blank of floor tile, preheating and punching.

Description

A kind of mould and application thereof of making floor tile

Affiliated technical field

The present invention relates to a kind of mould of making floor tile, and the method for making floor tile with this mould.

Background technology

Especially the plastic cement combined floor is because its environmental protection, light weight, cool in summer and warm in winter for combined floor, and style is various etc. and enjoy liking of consumer, replaces traditional solid wood floor tile and ceramic tile etc. more gradually on America and Europe and other places.

Traditional plastic cement combined floor sees also the profile of accompanying drawing 1 traditional floor tile, and this floor tile is generally formed by three layers, and ground floor is the transparent bed of material 1 ', and this layer is positioned at the top of floor tile, the anti-wear performance of principal security floor tile and service life; The second layer is a decorative layer 2 ', mainly determines the pattern of floor tile, makes it satisfy the demand of consumer to the floor tile aesthetic feeling; The 3rd layer is bed material 3 ', determines the thickness of floor tile and guarantees that it reaches certain anti-seismic performance.Fitting through hot pressing for these several layers is integral by size, shape need again, is washed into certain shape.Traditional floor tile system uses directly punching press type from top to bottom of punch die, the surface of product and side cutout are vertical mutually, the punch die of this kind plastic cement is generally shown in the decomposition and constitutional diagram of Fig. 3 punch die, punch die is mainly by stamping knife 5, base plate 6 constitutes, the sheet number of this stamping knife 5 is corresponding with the limit of base plate, when base plate is quadrangle, punching sheet number is four, stamping knife is fixed on four limits of base plate 6 by bolt 4, wherein is processed with cutting edge 51 on the stamping knife 5, during production, punch die moves down under pressure, cutting edge 51 provides the cut-out function, and the semi-finished product punching out is become required size, and the size of this base plate 6 has determined the dimensions of product.

Plastic cement combined floor outward appearance is imbued with aesthetic feeling, precisely because the primary raw material plastic cement is flavoursome sometimes, has limited use amount.Invented a kind of outward appearance novel floor tile identical in the industry with ceramic tile for this reason, this kind floor tile is shown in the profile of the novel floor tile of Fig. 2, this floor tile is with traditional the different of floor tile maximum: the hyaline layer 1 and the printed material 2 on the surface of this kind floor tile all are formed with a smooth curve to the side transition, and wrap the part side of bed material 3, because also having printed layers to cover with hyaline layer, this part that is wrapped covers, change traditional product and have only the deficiency of top-down otch, the vision and the impression effect of product have been increased, and broken away from traditional floor tile plastic cement and felt too heavy deficiency, so this kind product is promptly received the generally approval in market once emerging.But the production method of this kind floor tile is: have and the corresponding mould of new product in hot pressing bonding process, use, suppress required shape earlier, be washed into finished product with traditional punch die again, the disappearance of this kind mode of production is: because new product requires the shape symmetry, in the punching out process, position deviation promptly can't be reached symmetry a little, and speed of production is very slow and yield is very low.

Summary of the invention

The object of the present invention is to provide a kind of mould of making floor tile, and the method for making floor tile with this mould.

A kind of mould of making floor tile has stamping knife and base plate, is processed with cutting edge on the stamping knife, is processed into arc structure in the junction of stamping knife and base plate.

On the such scheme basis, form a recess in stamping knife of the present invention bottom, form a protuberance in the edge of base plate, the protuberance of base plate is corresponding with the recess size of stamping knife, is close fit after the assembling.

For improving the floor tile that the outward appearance that produces with mould of the present invention is imbued with aesthetic feeling, be processed with decorative pattern at plate upper surface.

A kind of method of utilizing mould to make floor tile, earlier with each layer of floor tile after semi-finished product are made in the hot pressing composite molding, re-use the punch die punch forming, wherein, before punching press, earlier blank is carried out preheating, make blank softening, and in the punch die forming process, it is the floor tile of circular shape that the blank side is subjected to the extruding of mould arc structure to form side structure.Its principle is to utilize mould of the present invention that semi-finished product are washed into predetermined dimensions, and simultaneously it is pressed into curved surface, thereby has improved speed of production and yields greatly.

Superiority of the present invention is: mold production process is simple, with the floor tile yields height of its manufacturing.

The specific embodiment

Embodiment 1

Shown in the punch die structure generalized section of using in Fig. 4 present embodiment, a kind of mould of making floor tile, it uses CNC or other processing mode that metal material is directly milled out and gets, it comprises stamping knife and the base plate 7 that is made into integration, the top of stamping knife is formed with cutting edge 71 through processing and grinding, is processed into arc structure 72 in the junction of stamping knife and base plate.

Among the present invention,, can on die shoe, use CNC or chemical corrosion method in the surface, process various decorative patterns 73,, extrude decorative pattern on the surface of product simultaneously with in forming process for the outer surface that makes product is attractive in appearance.

Utilize the method for the novel floor tile of mould manufacturing of the present invention such as Fig. 2 to be: earlier with 3 three layers of hyaline layers 1, printed layers 2, initial bed prior to forming blank after the hot pressing composite molding on the vulcanizing press, re-use mould of the present invention, through the punch die punch forming, wherein, before punch forming, semi-finished product are heated, make blank softening, directly blank is carried out preheating before the punching press, its objective is to guaranteeing the embossing effect of product; Afterwards, the blank after the preheating is positioned over punching press punch die moulding on the mould shown in Figure 4 again, the technology of punching press punch die moulding is identical with traditional handicraft.In punching course, cutting edge cuts into required size with product, behind the well cutting product again under pressure by punch die surface 73, circular arc 72 and stamping knife 7 common bag pressures, and produce the goods that required side has certain radian.
