Abstract

The utility model relates to a hot pressing mould for a relief shaving board, which comprises an upper pressing board, a lower pressing board, and a carving moulding board between the upper pressing board and the lower pressing board. The moulding board comprises a metal board on which relief patterns are processed and a teflon coating layer with thickness of 0.08 to 0.15 mm, and the thickness of the metal board is 30 to 50 mm. The surfaces of the relief patterns of the moulding board are smooth and clean, with mould withdrawing pitch more than 3 DEG. The utility model can be used on a hot press; a cabinet door, or a closet door, or a board, or a wire with the relief patterns or various abnormal cross sections can be pressed on a shaving board or a medium density fiberboard; the utility model can be used in the process of producing the relief shaving board or the medium density fiberboard.

Description

Hot-pressed die set for relief shaving board

The utility model relates to embossment particieboard hot pressing die, more clearly say so in building decoration and furniture manufacturing industry, must not engrave, mill machining, but in particieboard or medium density fibre board (MDF) hot pressing, be used for the embossment particieboard hot pressing die that direct heat extrudes embossing pattern particieboard or medium density fibre board (MDF).

At present, in China's particieboard manufacturing industry, can only produce the plate particieboard or the medium density fibre board (MDF) of all thickness.This plate particieboard or medium density fibre board (MDF) must be through just obtaining having sheet material, wire rod and the cabinet door of embossing pattern or various geometrical pattern cross sections after the machinings such as engraving, mill.And the surface of chipboard layer tissue is fine and closely woven, the thick pine of sandwich layer tissue.After machinings such as engraving, mill, not only intensity will reduce significantly, and because of the thick tissue of sandwich layer exposes, is difficult to carry out top finishing.Therefore, in building decoration, furniture manufacturing industry, the application of particieboard and medium density fibre board (MDF) is very limited.On the other hand, along with the raising of people's living standard, various carved furnitures and building decoration have been come into huge numbers of families, only depend on the solid wood resource not satisfy requirement far away.

The purpose of this utility model, just be to overcome above-mentioned shortcoming and defect, provide a kind of without machining, use original hot-press equipment just can be in particieboard or medium density fibre board (MDF) hot pressing hot pressing go out embossing pattern or various profiled cross-sections, can save timber resources in a large number, particieboard intensity does not reduce, the embossment particieboard hot pressing die of surperficial fine and closely woven paintable.

In order to achieve the above object, the utility model embossment particieboard hot pressing die is a carved template between top board and the lower platen.Carved template is made of following metallic plate and the polytetrafluorethylecoatings coatings that is processed with embossing pattern.Top board and lower platen then are the top board and the lower platen of hot press.Embossing pattern below the carved template is used for that hot pressing goes out embossing pattern on particieboard or medium density fibre board (MDF).Because processing is that hot pressing is carried out, for avoiding carved template and particieboard or medium density fibre board (MDF) adhesion, cause finished product to lose flesh, on the embossing pattern face of carved template, sprayed polytetrafluorethylecoatings coatings.

Carved template is processed by the steel plate or the cast iron plate of thickness between 30～50 millimeters.Carved template is thin excessively, and intensity difference, embossing pattern are dark inadequately.Carved template is blocked up, heavy inconvenience, waste material.Polytetrafluorethylecoatings coatings thickness is best with 0.08～0.15 millimeter timeliness effect.Too thick, influence the definition of embossing pattern, the adhesive force of coating and template also decreases.Too thin, coating is fragile, causes the adhesion of particieboard and template.

The surface roughness of the embossing pattern of engraving tool transverse slat is not less than 0.8, and its pattern draft is not less than 3 °.Particieboard or medium density fibre board (MDF) embossing pattern that bright and clean embossing pattern surface goes out hot pressing are clear, bright and clean, otherwise will blur, coarse.Pattern draft is during less than 3 °, and embossing pattern is difficult for being shaped, easily adhesion.When pattern draft is not less than 3 °, clear, the easy shaping of embossing pattern.

The task of the utility model embossment particieboard hot pressing die comes to this and finishes.

The utility model can suppress embossing pattern or various profiled cross-section in particieboard or medium density fibre board (MDF) hot pressing under the situation of using original particieboard production equipment (hot press).And can provide semi-finished product such as sheet material with embossing pattern and various geometrical pattern cross sections, wire rod, cupboard door, cabinet door to market.These particieboards or medium density fibre board (MDF) raised piece intensity do not reduce, surperficial fine and closely woven paintable, and the outward appearance grace can substitute, save a large amount of timber, and its value also improves a lot.Compare increment 40～60% with the particieboard in past.It can be widely used in the production of embossment particieboard in the industries such as furniture manufacturing, building decoration or medium density fibre board (MDF).

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.

Structural representation when Fig. 1 is the utility model embossment particieboard hot pressing die embodiment 1 work.

Fig. 2 is the schematic diagram of the embossment particieboard of use the utility model embodiment 1 production.

Fig. 3 is the schematic diagram of the particieboard of past production.

Among Fig. 1, the utility model embodiment 1 is made of top board 1, lower platen 2, carved template 3, and 6 is by the particieboard of hot pressing.Carved template 3 is made of metallic plate 4 and polytetrafluorethylecoatings coatings 5.Metallic plate 4 is that 40 millimeters steel plate is made by thickness.Polytetrafluorethylecoatings coatings 5 thickness are 0.1 millimeter.The following surface roughness of carved template is 0.8, and its pattern draft is 3 °.

Among Fig. 2, use embossment particieboard that the utility model embodiment 1 produces by fine and closely woven superficial layer 1 and 2 and the sandwich layer 3 of thick pine constitute.Superficial layer 1 decorative pattern that has an embossing pattern is clear, any surface finish, organize fine and closely woven, intensity is high.

Among Fig. 3, the particieboard in past is made of superficial layer 1, superficial layer 2 and sandwich layer 3, and is flat, do not have embossing pattern.As machining process processing embossing pattern such as milling with engraving, superficial layer is with destroyed, and particieboard intensity descends, and covers with paint, lacquer, colour wash, etc. also difficulty.

Embodiment 1 can be widely used in the processing of thin particieboard of embossment or medium density fibre board (MDF).
