Abstract

The utility model provides a sizing mould of a surface coextruded wood-plastic floor. An upper mould sizing concave surface (11) is formed on an upper mould (1); a lower mould sizing concave surface (21) is formed on a lower mould (2); a sizing block (3) is formed by a sizing block body (32) and a bulge (31); the bulge (31) is formed on the sizing block body (32); a step (33) is formed between the bulge (31) and the sizing block body (32); an upper mould water outlet groove (111) is formed on the inner surface of the upper mould sizing concave surface (11); a lower mould water outlet groove (211) is formed on the inner surface of the lower mould sizing concave surface (21); the upper mould water outlet groove (111) and the lower mould water outlet groove (211) are communicated with circulating cooling water; and inclined planes (1-2) are formed on openings of the upper mould water outlet groove (111) and the lower mould water outlet groove (211). According to the sizing mould disclosed by the utility model, the quality of a product is ensured; a phenomenon that plastic on the surface of the wood-plastic floor is contacted with the sizing mould to generate wrinkles when the plastic is not cooled is avoided; and meanwhile, the mould is effectively prevented from being blocked.

Description

A kind of stock mould of surperficial co-extrusion Wood-plastic floor

Technical field:

The utility model relates to technical field of floor, more specifically to used shaper in a kind of Wood-plastic floor production process.

Background technology:

Wood plastic composite be a kind of be basic material and thermoplastic macromolecule material and processing aid etc. by timber (lignose, plant cellulose) mainly, the high-tech green material of making through die apparatus heating extrusion molding again after mixing, have performance and the feature of timber and plastics concurrently, can substitute the advanced composite material (ACM) of timber, plastics and metal, major product has the floor, wallboard, guardrail etc.

Adopt co-extrusion technology, plastics (as ASA, PE) are coated on common Wood-plastic floor, can improve the weatherability of Wood-plastic floor greatly, be i.e. surperficial co-extrusion Wood-plastic floor.The Wood-plastic floor of surface co-extrusion is when extrusion molding, and co-extrusion is in the condition of high temperature at the plastics of floor surface.And existing Wood-plastic floor mould, its mould mouth mould and stock mould size basically identical, stock mould contact with the plastics of floor surface easily, cause frosting to produce wrinkle, easily block up mould etc., are not suitable for the moulding of the Wood-plastic floor of surperficial co-extrusion.

The utility model content:

The purpose of this utility model is exactly the deficiency at prior art, and a kind of stock mould of surperficial co-extrusion Wood-plastic floor is provided, and it has guaranteed product quality, avoids the plastics on Wood-plastic floor surface to produce wrinkle, has effectively prevented the mould obstruction simultaneously.

Technology solution of the present utility model is as follows:

A kind of stock mould of surperficial co-extrusion Wood-plastic floor, comprise patrix, counterdie and shaped block, patrix, all form screw on counterdie and the shaped block, patrix, counterdie and shaped block are fixed together by screw, form patrix typing concave surface on the patrix, form counterdie typing concave surface on the counterdie, shaped block is made up of shaped block body and projection, projection is molded on the shaped block body, form step between projection and shaped block body, the inner surface of patrix typing concave surface forms the patrix effluent trough, and the inner surface of counterdie typing concave surface forms the counterdie effluent trough, and the patrix effluent trough connects mutually with counterdie effluent trough and recirculated cooling water; The opening part of patrix effluent trough and counterdie effluent trough all forms the inclined-plane.

Described step is made up of planar section and bevel phase, and the bevel phase of two relative shaped block constitutes horn opening, and two relative inclined-planes constitute horn opening.

The height of described bevel phase is 1/3 of whole shoulder height.

The beneficial effects of the utility model are:

1, it makes surperficial co-extrusion Wood-plastic floor can enter stock mould smoothly in the extrusion molding process, and the plastic layer to be cooled of Wood-plastic floor core outside does not contact with stock mould.

2, the plastics of Wood-plastic floor core outside rapid solidified surface plastics under the cooling water effect, this moment, the Wood-plastic floor sandwich layer was not finished cooling, can continue to finalize the design by stock mould.Guarantee product quality, avoided the plastics on Wood-plastic floor surface to produce wrinkle, effectively prevented the mould obstruction simultaneously.

The specific embodiment:

Embodiment: see shown in Fig. 1 to 8, a kind of stock mould of surperficial co-extrusion Wood-plastic floor, comprise patrix 1, counterdie 2 and shaped block 3, patrix 1, all form screw 4 on counterdie 2 and the shaped block 3, patrix 1, counterdie 2 and shaped block 3 are fixed together by screw, form patrix typing concave surface 11 on the patrix 1, form counterdie typing concave surface 21 on the counterdie 2, shaped block 3 is made up of shaped block body 32 and projection 31, projection 31 is molded on the shaped block body 32,

projection

31 and 32 formation steps 33 of shaped block body, the inner surface of patrix typing concave surface 11 forms patrix effluent trough 111, the inner surface of counterdie typing concave surface 21 forms counterdie effluent trough 211, and patrix effluent trough 111 connects mutually with counterdie effluent trough 211 and recirculated cooling water; The opening part of patrix effluent trough 111 and counterdie effluent trough 211 all forms inclined-plane 1-2.

Described step 33 is made up of planar section 331 and bevel phase 332, and the bevel phase 332 of two relative shaped block 3 constitutes horn opening, and two relative inclined-plane 1-2 constitute horn opening.

The height of described bevel phase 332 is 1/3 of whole step 33 height.

Operation principle: Wood-plastic floor to be formed is through the utility model the time, the plastics on Wood-plastic floor surface to be formed cool off rapidly through the recirculated cooling water on patrix effluent trough 111 and the counterdie effluent trough 211, guaranteed product quality, avoid the plastics on Wood-plastic floor surface when uncolled, to produce wrinkle etc. in the stock mould contact, influence co-extrusion Wood-plastic floor presentation quality.

Because the bevel phase 332 of two relative shaped block 3 constitutes horn opening.The co-extrusion Wood-plastic floor can enter stock mould smoothly in the extrusion molding process, guarantee that the plastics of Wood-plastic floor core outside do not come in contact with the utility model stock mould, thereby effectively prevented the mould obstruction.
