Low-consumption lower die plate of PVC foam board extrusion die

A low-consumption lower die plate of a PVC foam board extrusion die comprises a lower die plate body, one end of the lower die plate body is fixedly connected and communicated with an extrusion pipeline, the end, away from the lower die plate body, of the extrusion pipeline is fixedly connected and communicated with an extrusion die opening, and a feeding channel is formed in the middle of the side, away from the extrusion die opening, of the lower die plate body; the lower die plate has the advantages that the lower die plate is easy to operate and convenient to use, the lower die plate is used in cooperation with a corresponding upper die plate, the uniformity of raw materials during extrusion and the accuracy after forming can be effectively guaranteed, and the raw materials can be conveniently and rapidly extruded. Compared with the prior art, the utility model has the advantages of effectively reducing the reserved part during product extrusion, reducing the raw material cost during production, avoiding
