Mold for life raft floating tire production

Abstract

The invention discloses a mold for life raft floating tire production, and relates to the technical field of life raft manufacturing. The mold for life raft floating tire production comprises an outer wrapping sleeve and an inner supporting sleeve, and the inner supporting sleeve is arranged in the outer wrapping sleeve. The outer wrapping sleeve is composed of two semicircular plates, the outer wall of the outer wrapping sleeve is rotationally connected with a supporting column, a stabilizing plate is fixed to the bottom of the supporting column, and the top of the supporting column is fixed to the top of the inner supporting sleeve. According to the mold for life raft floating tire production, by arranging the outer wrapping sleeve and the inner supporting sleeve, the auxiliary forming effect on hot rubber can be achieved, and the rubber can naturally form a hollow cylinder shape after being cooled. And a driving mechanism, an air blowing mechanism and a pneumatic through pipe are arranged, air blowing can be conducted on the part between a floating tire and the inner supporting sleeve through rotation of the outer wrapping sleeve in the demolding process, the inner side of the floating tire and the outer side of the inner supporting sleeve can be separated through the gas, the viscosity between the floating tire and the inner supporting sleeve is reduced, and therefore the demolding speed of the floating tire is increased.

Description

technical field [0001] The invention relates to the technical field of life raft manufacturing, in particular to a mold for the production of life raft floating tires. Background technique [0002] A life raft is a non-self-propelled boat used for lifesaving on a ship. There is a certain amount of food and fresh water in the life raft for the crew to use while drifting at sea. Life rafts can be divided into rigid life rafts and inflatable life rafts according to their structure. [0003] The inflatable liferaft belongs to the inflatable liferaft. This type of liferaft is provided with buoyancy by the upper and lower buoyant tires made of rubber materials, and the buoyant tires are usually set in polygonal shapes with edges and corners. When the buoyant tires are produced, the injection molded The rubber material may partially stick together with the mold, which will have a certain impact on the demoulding efficiency of the floating tire.

[0003] The inflatable liferaft belongs to the inflatable liferaft. This type of liferaft is provided with buoyancy by the upper and lower buoyant tires made of rubber materials, and the buoyant tires are usually set in angular polygonal shapes. When the buoyant tires are produced, the injection molded The rubber material may partially stick to the mold, which will have a certain impact on the demoulding efficiency of the floating tire
