Die plate with adjustable outlet size

Abstract

The invention discloses a die plate with an adjustable outlet size. The die plate comprises a die plate lower plate and a die plate upper plate, the middle part of the die plate upper plate is slidably connected with a movable seat, an insert block group is arranged at the bottom of the movable seat, the bottom part of the insert block group is in a tread profile shape, the insert block group is formed by splicing insert blocks, a cushion block is arranged on the surface of the die plate lower plate, a fixed rod is fixedly connected in the die plate lower plate, both ends of the die plate upper plate are fixedly connected with fixed seats, both sides of the top of the die plate lower plate are fixedly connected with fixed frames, the top parts of the fixed seats are fixedly connected withhydraulic rods, the working ends of the hydraulic rods are fixedly connected with the fixed frames, and a height adjusting device is arranged between the movable seat and the die plate upper plate. The invention relates to the technical field of tire production devices. The die plate with the adjustable outlet size solves the problem that the outlet size of the die plate cannot be adjusted, and avoids the need of replacing the entire die plate when one part is damaged at the same time, so that production costs are reduced.

Description

technical field [0001] The invention relates to the technical field of tire production devices, in particular to a die plate with adjustable outlet size. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. The tread is an important component of the tire. The tread extrusion pressure die plate includes a ...
