Vulcanizing mold for air spring leather bag

Abstract

The invention discloses a vulcanizing mold for an air spring leather bag. The vulcanization mold comprises an upper mold, a middle mold and a lower mold, at least one vulcanization hole is formed in the middle mold, the upper mold is provided with a first plunger used for blocking one end of the vulcanization hole, the lower mold is provided with a second plunger used for blocking the other end of the vulcanization hole, a heating pipeline is arranged in the middle mold, a capsule is in a straight tube shape, one end is sealed, the other end is fixed to the second plunger in a sealed mode, a vulcanization chamber is formed among the first plunger, the second plunger, the inner wall of the vulcanization hole and the outer wall of the capsule, and the air spring leather bag is arranged outside the capsule in a sleeving mode and is located in the vulcanization chamber; a vacuumizing header pipe is arranged in the upper mold and communicates with the vulcanizing chamber; and an air charging and exhausting pipeline is arranged in the lower mold and communicates with the interior of the capsule. The mold is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of vulcanization molds, in particular to a vulcanization mold for an air spring bladder. Background technique [0002] In order to quickly attenuate the vibration of the frame and the cab of the vehicle body and improve the ride comfort and comfort of the car, the suspension system of the car is generally equipped with an air spring bag to reduce vibration, and the air spring bag is widely used in the car. [0003] For example, the Chinese invention patent application number 202011185365.8, the patent name is a vulcanization mold and vulcanization process for an air spring bladder. Attached to the air spring bladder, the capsule expands when heated and the compartment is compressed when it is attached to the air spring bladder, which causes the capsule to expand under heat and vulcanize under pressure (expansion under pressure) for a long time to become cooling contraction and pressure release contraction, resulting i...

Problems solved by technology

[0003] For example, the Chinese invention patent application number 202011185365.8, the patent name is a vulcanization mold and vulcanization process for an air spring bladder. Attached to the air spring bladder, the capsule expands when heated and the compartment is compressed when it is attached to the air spring bladder, which causes the capsule to expand under heat and vulcanize under pressure (expansion under pressure) for a long time to become cooling contraction and pressure release contraction, resulting in The service life of the capsule is shortened; 2: After the air spring bladder is put on the mandrel, the upper center guide rod is driven down by the upper center cylinder to move down to the set position, and then the upper base of the mold and the middle mold are driven down together by the clamping cylinder Move to the set position to realize the mold. Therefore, the product is placed from the bottom. In case the middle mold presses the product or the product is not completely placed in the interval cavity, the operator will not know anything

3: The first middle mold has a first heating chamber that can pass through high-temperature steam, and the second middle mold has a second heating chamber that can pass through high-temperature steam. Both the first heating chamber and the first heating chamber are connected with air intake The middle part of the core mold has a third heating chamber that can be fed with high-temperature steam, and the high-temperature steam is passed into the air chamber through the air inlet pipeline on the middle mold. During the vulcanization process, the above-mentioned mold needs 4 channels For heating, there are many steam lines, and the heating effect is poor. If the compartment area is fixed, when the heating effect is good, only high temperature vulcanization is required for air spring bladder vulcanization, and nitrogen vulcanization and pressure-holding vulcanization are not required, but because In the above technology, the compartment is compressed so that the capsule is attached to the air spring leather bag, then nitrogen gas pressure must be required to inflate the capsule, and then nitrogen vulcanization and pressure vulcanization can be realized. The process is more cumbersome.
