Mould pressing floor board and manufacturing method and mould thereof

Abstract

The invention provides a mould pressing floor board and a manufacturing method and a mould thereof. The mould pressing floor board comprises a surface compound layer and a base material layer which are overlapped up and down, wherein an upper extension part and a lower extension part are respectively formed on two surfaces of the base material layer through the mould; next, the surface compound layer and the base material layer are mould-pressed after being overlapped; joint tongues are respectively formed on the upper extension part by using position and structure relationships after the overlapping of the surface compound layer and the base material layer; mortises matched with the joint tongues are formed between the upper side of the lower extension part and the lower side of the surface compound layer, so that the splicing between every two adjacent mould pressing floor boards is realized. By applying the mould pressing floor board and the manufacturing method and the mould thereof, the problems caused by floor board grooving can be avoided; in mould pressing, the raw material of the mould pressing floor board is high in utilization rate, so that the manufacturing cost of the floor board is reduced; moreover, the mould pressing floor board is high in shape precision and stable in dimension; the splicing between the mould pressing floor boards is tighter and more attractive; the problem that the installation of the mould pressing floor board is influenced due to mortise blockage is also solved.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a molded floor, a method for manufacturing the molded floor, and a mold for manufacturing the molded floor. Background technique [0002] In the floor covering industry, the earliest large-scale application is the hard wood floor produced and processed by slotting technology. However, wood floor is a large consumer of wood, and the wood resources available to humans are limited. Long-term damage to forests Restricted felling and soil erosion caused human beings to pay a heavy price. It has been the mission of the floor covering industry to find a substitute for solid wood flooring. With the development of technology, elastic floors such as polyvinyl chloride (PVC) floors, rubber floors, cork floors, wood-plastic floors, etc. have appeared. When manufacturing, the materials of these elastic floors are made into sheets according to their respective formula requirements, and then Mu...

AI Technical Summary

Problems solved by technology

[0005] 1. Poor dimensional stability

The elastic floor is generally thinner than the hard wood floor, the size of the corresponding grooved part is smaller than the hard wood floor, and the elastic floor itself is soft, plus the mechanical error of the slotting machine, the accuracy of the tenon and tongue is poor, and the groove After the floor is difficult to accurately form a strict rectangle or square

[0006] 2. Severe tool wear

Since the elastic floor (such as PVC block floor tiles, etc.) contains a large amount of stone powder, even the proportion of stone powder is as high as 70%, the cutter is easy to wear when slotting, causing economic losses, and the quality of the product will be affected if the cutter is not replaced in time bigger

[0007] 3. Large loss of floor effective area

[0008] 4. A lot of dust is generated when slotting

Like hard wood flooring, elastic flooring will generate a lot of dust when grooved, and the operating environment is poor. Although it can be greatly improved through a strong ventilation and recovery system, the cost of electricity and equipment investment is not small

In addition, the groove size of elastic floor (such as PVC block floor tiles, etc.) is smaller than that of hard wood floor, and fine dust particles can easily block the already narrow groove groove, affecting the installation
