Novel SPC floor die

Abstract

The invention relates to the technical field of floor dies, in particular to a novel SPC floor die. The novel SPC floor die comprises an upper die body, an upper die lip, an upper die lip adjusting plate, an upper die lip adjusting cored screw, a lower die body, a lower die lip, a lower die lip adjusting plate and a lower die lip adjusting cored screw. The die is composed of the upper die body andthe lower die body, the upper die body and the lower die body are not spliced, material accumulation and adhesion are avoided, forming is fast, the continuous starting time is long, and the production cost is lowered; the thickness range of a universal SPC floor in the market is 3-8 mm, the size of die orifices is changed in a fine adjustment mode through elastic deformation of an upper die orifice and a lower die orifice, the use of a graduated scale is coordinated, so that elastic deformation of a die material can be ensured to be within the allowable range, the production requirements canbe met, and base plates with different thicknesses can be produced; and the die is simple in repair, cleaning and maintenance, and the production efficiency of the floor is improved.

Description

technical field [0001] The invention relates to the technical field of floor molds, in particular to a novel SPC floor mold. Background technique [0002] The floor is a kind of ground decoration material. There are many classifications of floors, classified by structure: natural landscape Fengshui floor, solid wood floor, reinforced composite wood floor, solid wood composite floor, bamboo wood floor, cork floor, etc.; classified by use: floor for household occasions, floor for commercial occasions, Anti-static floor, outdoor floor, special floor for stage dance, special floor for sports hall, special floor for track and field, etc.; classified by environmental protection level: E1 grade floor, E0 grade floor, JAS star standard F4 star floor, etc. In the Chinese market, there are some special geothermal floors. In fact, as long as the base material is stable, no cracking, no deformation, high environmental performance, heat preservation and heat conduction, even pure solid ...

AI Technical Summary

Problems solved by technology

[0006] However, it still has the following disadvantages: because there is a splicing seam on the upper mold in the mold flow channel, under the normal production pressure of the extruder, the splicing seam is subject to greater pressure from the mold expansion, and material is easy to accumulate at the splicing seam, resulting in the production of There are mechanical traces on the surface of the board, which affects the quality of the board surface, and the continuous heating of the PVC material accumulated in the joint is easy to carbonize and corrode the mold. , which increases the production cost, and the mold cleaning and maintenance are troublesome, and the production efficiency is low
