Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] The vulcanization molding method of the floater of the present invention has the following steps: 1) Preheating the mold; 2) Putting raw materials into the mold; 3) Pressurizing the raw materials by the mold so that the raw materials melt and flow into the mold cavity. Reciprocate up and down on the pressurized template to extrude the melted raw materials to squeeze out the air; 4), the vulcanization of the float is completed, the mold is opened and the float is ejected from the mold; 5), repeat 2) to 4) to cycle Production.

[0019] The temperature of the upper mold of the mold is controlled within the range of 121°C ± 5°C, and the temperature of the lower mold of the mold is controlled within the range of 115°C ± 5°C. The upper mold of the mold is used to pressurize the raw material to melt the raw material and flow into the lower part of the mold. The mold, the l...

Abstract

The invention discloses a floater vulcanizing molding method by adopting which air can not be remained in a floater or on the surface of the floater and a mould for implementing the method, so that the density distribution of the floater is uniform, the oil resisting stability is improved and the reliability and the durability of the floater are further improved. The floater vulcanizing molding method comprises the following steps: (1) pre-heating the mould; (2) adding raw materials into the mould; (3) pressurizing raw materials by adopting the mould so that the raw materials are smelted to flow into a mould cavity, wherein the mould is used for squeezing the smelted raw materials by up and down reciprocating motion of a pressurized template to extrude and exhaust air; (4) performing vulcanizing molding on the floater and opening the mould to eject the floater out of the mould; and (5) repeating steps (2)-(4) for carrying out circular production.

Description

technical field [0001] The invention relates to the technical field of float molding, in particular to a float vulcanization molding method and a mold for implementing the method. Background technique [0002] In the existing float vulcanization molding method, after the float is formed, air remains inside or on the surface of the float, resulting in uneven density distribution or surface cracking of the float, which makes the oil resistance stability of the float low, thereby reducing the reliability and durability of the float. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a float vulcanization molding method that can prevent air from remaining inside or on the surface of the float and a mold for implementing the method, so that the density distribution of the float is uniform, and the oil resistance stability is improved at the same time. The reliability and durability of the float. [0004] The technical s...
