Referring to fig. 1-5, the invention is a composite forming die for solid pore-free floors in outdoor gardens, comprising a die body 16, a transition plate II 15, a transition plate I13, a support 26, a die II 10, a die I27, a water jacket II 5, a water jacket I4, a cavity and a core rod, wherein the core rod is positioned in the cavity and the length of the core rod extends from the support to the die I, wood-plastic foaming material injection runners 9 for the outer layer of a composite floor are arranged on the upper and lower sides of the cavity on the end surface of the die II adjacent to the die I, carbon fiber threading channels 11 are symmetrically arranged up and down and obliquely and sequentially penetrate through the support and the die II to reach the composite part of the core rod and the mouth part of the outer layer wood-plastic foaming material injection runner, the middle of the cavity 28 is used for PVC foaming material circulation of the inner layer of the composite floor, a section of a bent runner A8 is arranged at, the included angle between the bent flow passage A and the central plane is 60-62 degrees; the front end of the carbon fiber threading channel is provided with a bent flow passage B21, and the included angle between the bent flow passage B and the central plane is 30 degrees; a cooling water hole 20 which circularly flows is also arranged at the tip part of the inner part of the second mouth die close to the bent flow passage B and is communicated with an external cooling water source; the core rod divides the cavity, the core rod is formed by buckling an upper core rod 7 and a lower core rod 22, the upper core rod and the lower core rod together divide a PVC foaming material circulation channel of the inner layer into an upper PVC foaming material flow channel 14, a middle PVC foaming material flow channel and a lower PVC foaming material flow channel 17, a plurality of exhaust ducts 6 are arranged in the upper core rod and the lower core rod, one ends of the exhaust ducts are communicated with the front end surface of the upper core rod or the lower core rod, and the other ends of the exhaust ducts extend to the support and are discharged from the support.

Furthermore, in this embodiment the cross-sectional shape front end in cooling water hole is triangle point shape, and the cross-sectional shape rear end in cooling water hole is the arc shape, and wherein the front end setting of triangle point shape orientation bending flow channel B.

Further, in the present embodiment, the PVC foam runner is divided into a front section 19 and a rear section 18, wherein the upper and lower width of the front section is smaller than the upper and lower width of the rear section, and the PVC foam flows from the rear section to the front section to form an extrusion on the PVC foam.

Further, in this embodiment, the upper core rod and the lower core rod are connected by buckling through the inner core rod leg 23.

The outer wood-plastic foaming material is injected into the runner from the wood-plastic foaming material and enters the die, the sheet enters the die from the carbon fiber sheet penetrating channel, the core layer PVC high-foaming reclaimed material enters from the inner PVC foaming material runner, the three strands of materials are converged inside the die, and the core layer PVC high-foaming reclaimed material is divided into three strands to be extruded and enter for compounding.

When a composite forming die is used for extrusion production, when PVC high-foaming recycled materials are combined with carbon fiber sheets and wood-plastic foaming materials, air holes are formed for breaking walls, irregular small broken holes appear on the cross section of a solid floor product, and the attractiveness and the strength of the product are affected. Greatly influences the service life of the die, and is a great innovation of the die.

When the PVC high-foaming recycled material of the core layer is discharged and combined with the wood-plastic foaming material of the outer layer and the high-strength sheet material of the interlayer carbon fiber, circulating cooling water can be introduced into the cooling water holes to carry out micro-cooling on the sheet material coming from the front tip part of the bending flow channel B and the mixed material after the water is introduced (wherein cooling gas can also be introduced for carrying out blow-cooling), so that the discharged material is slightly skinned, the discharged material is more regular in forming, and the combination with the outer layer fabric and the carbon fiber sheet material is more facilitated.

Through repeated tests, the angle of the carbon fiber penetrating high-strength sheet is 30 degrees, so that the resistance when the sheet is combined with the core layer PVC high-foaming recycled material is greatly reduced, the bevel angle degree when the outer layer wood-plastic foaming material is combined with the core material is 60 degrees, if the bevel angle degree is too small, the processing space of a die is not enough, the strength and the service life of steel materials are reduced after the die is processed for many times, the die is easy to extrude and deform to cause die scrap, if the bevel angle is too large, the resistance when multiple material flows are combined is too large, the material flows are not easy to form the requirement which meets the extrusion mechanics, the material flows are retained at the junction of the three material flows, paste is formed after long time, meanwhile, the material can be turned over from the position where the die cavity cuts through the sheet, normal extrusion production can not be realized, through repeated tests, the 60-62 degree bevel angle can achieve a better extrusion effect, and meanwhile, the mold cavity is cut, the carbon fiber sheet penetrates into the mold cavity through the cut space, if the sheet penetrating degree is too large, the sheet penetrating resistance is increased, the core layer PVC high-foaming material and the outer layer wood-plastic foaming material can flow out of the mold through the cut space of the sheet, the sheet is easy to deform and tear, and a product cannot be extruded normally.

After mechanical calculation and repeated multiple scheme debugging tests, the obtained feeding degree of the outer layer wood-plastic foaming material is optimal when being 60 degrees, so that the fabric can be ensured to extrude carbon fibers and core materials compactly, and can also form forward extrusion force on the premise of extrusion compactness, two material flows are formed to drive carbon fiber sheets to be extruded forwards together, and the normal extrusion production requirement of a die is met.

Fig. 6 is a schematic view of the installation state of the die in use, wherein carbon fiber high-strength sheets are led out from an upper carbon fiber sheet reel and a lower carbon fiber sheet reel through related guide mechanisms, enter a bracket and a die II and are finally converged with other two material flows in the die cavity of the die to be compounded.

The invention can reduce the requirement on the internal core material by subversive improvement design, namely the core material can be used for replacing the broken variegated material of the PVC foaming product produced by the past normal production, but can also meet the corresponding performance requirement, so that the produced outdoor garden floor product has strong weather resistance, shrinkage resistance, water resistance, high impact resistance, low deformation rate, light weight and greatly reduced cost, meets the national environmental protection requirement and is more suitable for mass popularization.
