Abstract

The invention discloses a PVC foaming plate extrusion die, and relates to the technical field of foaming plate extrusion dies. The PVC foaming plate extrusion die comprises a lower die plate and an upper die plate matched with the lower die plate, a flow-division buffer zone, a flow equalization zone and a forming die groove are arranged at the upper surface of the lower die plate in a mode of sequentially communicating with a feeding port, wherein the flow-division buffer zone comprises a buffer groove, a pair of L-shaped guide grooves communicating with the buffer groove are symmetrically formed at the positions, located on the two sides of the buffer groove, of the upper surface of the lower die plate, rectangular flow guide holes are linearly arranged on the opposite side surfaces of the pair of L-shaped guide grooves and at the ends, away from the flow-division buffer zone, of the pair of L-shaped guide grooves, a T-shaped flow guide groove communicating with the feeding port is formed in the lower surface of the upper die plate, the T-shaped flow guide groove communicates with the buffer groove and the pair of L-shaped guide grooves correspondingly, and a pair of L-shaped connection guide grooves are symmetrically fixed on the lower surface of the upper die plate. According to the PVC foaming plate extrusion die, through the lower die plate and the upper die plate which are designed, a foaming material enters the forming die groove in three directions, a PVC foaming plate is easier to form rapidly, so that the problem that the efficiency is low when an existing die isused for forming the PVC foaming plate is solved.

Description

technical field [0001] The invention belongs to the technical field of foam board extrusion dies, in particular to a PVC foam board extrusion die. Background technique [0002] The design of the flow channel structure formed by the combination of the current upper template and the lower template is unreasonable. When the PVC foam board is finished, there is a certain difference in density and thickness between the inlet of the forming cavity and the rear end. The PVC foam board is used after being cut off, the effective use area for material forming is reduced, and a large amount of material is wasted in production. In order to fill the mold forming space with materials, the corresponding mold needs to increase the forming time during forming, which reduces the production efficiency. . Contents of the invention [0003] The object of the present invention is to provide a PVC foam board extrusion die, through the design of the lower template and the upper template foaming ...
