Embodiment Construction
[0017] The present invention will be further described below in conjunction with the drawings.
[0018] The float vulcanization molding method of the present invention has the following steps: 1), mold preheating; 2), put raw materials into the mold; 3), the mold pressurizes the raw materials to melt the raw materials and flow into the mold cavity, during which the mold uses The molten material is squeezed up and down on the pressurized template to squeeze out the air; 4) The float is vulcanized and formed, the mold is opened and the float is ejected from the mold; 5), repeat 2) ~ 4) for the cycle produce.
[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 materials to melt them and flow into the bottom of the mold. Mold, the lower mold of the mold and the upper mold of the mold ...

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 float, resulting in uneven density distribution or surface cracking of the float, resulting in low oil resistance stability of the float, thereby reducing the reliability and durability of the float. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a float vulcanization molding method and a mold for implementing the method so that no air will be retained in the interior or surface of the float, so that the density distribution of the float is uniform, and the oil resistance stability is improved, thereby improving The reliability and durability of the float. [0004] The technical scheme of the present invention...
