Abstract

The invention discloses a PVC foam board extrusion die and relates to the technical field of foam board extrusion dies. The present invention includes a lower template and an upper template matched with the lower template. The upper surface of the lower template is connected with the feeding port in sequence with a diversion buffer zone, a flow equalization zone, and a molding groove; the diversion buffer zone includes a buffer tank; the upper surface of the lower template is located at A pair of L-shaped guide grooves connected with the buffer groove are arranged symmetrically on both sides of the buffer tank; a pair of L-shaped guide grooves are arranged linearly on the opposite side and away from the diversion buffer zone, and a rectangular diversion hole is arranged; the lower surface of the upper template is provided with a feeding The T-shaped diversion groove connected to the mouth; the T-shaped diversion groove communicates with the buffer groove and a pair of L-shaped guide grooves respectively; a pair of L-shaped connecting guide grooves are symmetrically fixed on the lower surface of the upper template. In the present invention, the designed lower template and the upper template are foamed into the molding cavity in three directions, and the PVC foam board is easier to be quickly formed, and the problem of low efficiency of the existing mold in molding the PVC foam board 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 ...
