Composite forming die for solid non-air-hole floor in outdoor garden

Abstract

The invention relates to a composite forming die for a solid non-air-hole floor in an outdoor garden. The composite forming die comprises a die body, a second transition plate, a first transition plate, a support, a second opening die, a first opening die, a second water jacket, a first water jacket, a cavity and a core rod; a section of bent flow channel A is arranged at the front end of a wood-plastic foaming material injection flow channel, and the included angle between the bent flow channel A and the center plane is 60-62 degrees; a bent flow channel B is arranged at the front end of a carbon fiber sheet penetrating channel; a circularly flowing cooling water hole is further formed in the tip part, close to the bent flow channel B, inside the second opening die; an upper core rod and a lower core rod divide a PVC foaming material circulation channel on the inner layer into an upper PVC foaming material flow channel, a middle PVC foaming material flow channel and a lower PVC foaming material flow channel; and a plurality of exhaust ducts are formed in the upper core rod and the lower core rod. According to the composite forming die, not only is the biggest defect of an existing die overcome, but also the effects that the product performance is not reduced while the material losses of the produced and formed product are reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of profile extrusion molding dies, in particular to a composite molding die used for solid non-porous floors in outdoor gardens. Background technique [0002] At present, in outdoor gardens and other outdoor public places, high-strength and high-strength outdoor wood-plastic floors are laid in many places. This kind of floor is a composite extrusion floor. And the carbon fiber layer in the middle is composited. The composite molding of these three layers is made by extruding wood-plastic materials through an extrusion mold. Due to the limitation of its own structural design, the floor produced by this extrusion mold There will be a lot of small air holes on both sides of the carbon fiber layer in the middle of the product. There are small air holes in the produced product, which is not obvious at the beginning of use, but because this kind of floor is outdoors and other conditions are relatively harsh. Used...

[0002] At present, in outdoor gardens and other outdoor public places, high-strength and high-strength outdoor wood-plastic floors are laid in many places. This kind of floor is a composite extrusion floor. And the carbon fiber layer in the middle is composited. The composite molding of these three layers is made by extruding wood-plastic materials through an extrusion mold. Due to the limitation of its own structural design, the floor produced by this extrusion mold There will be a lot of small air holes on both sides of the carbon fiber layer in the middle of the product. There are small air holes in the produced product, which is not obvious at the beginning of use, but because this kind of floor is outdoors and other conditions are relatively harsh. Used in the environment, it is often trampled by people, and the wear and tear is very serious. The floor with small pores is used for a little longer, and the pores are easy to be trampled and collapsed, resulting in local damage, and gradually evolve into large-scale damage; at the same time, the production of outdoor gardens Due to its own design flaws in the extrusion molding mold for wood-plastic flooring, when extruding, the carbon fiber sheet does not enter the mold at the beginning, and the wood-plastic material of the inner and outer layers often easily escapes from the gap at the die. At the same time, the wood-plastic materials of the inner and outer layers of the composite floor produced by the existing molds are all made of the same material to achieve the corresponding performance effect, and it is difficult to achieve the corresponding performance by replacing the material.
