The invention discloses a vulcanization forming mold and a vulcanization forming method of a rubber corrugated diaphragm for an automobile pump, and belongs to the field of rubber vulcanization equipment. According to the vulcanization forming mold, a lower mold is provided with an air channel communicating with the outside; one end of an inner mold core of a hollow structure is movably connected with a floating mold core, and the other end communicates with the air channel; a containing cavity is formed in a middle mold, and two sliding molds located on the two sides of the inner mold core are arranged in the containing cavity in a sliding mode; and two guide rods which are in driving fit with the two sliding molds are arranged on the face, facing the middle mold, of an upper mold. When the lower mold, the middle mold and the upper mold are opened, the two guide rods can respectively drive the two sliding molds to move back to the inner mold core, so that the rubber corrugated diaphragm is separated from the inner mold core; and then positive-pressure airflow can be blown into an airflow cavity through the air channel, so that the rubber corrugated diaphragm is separated from the inner mold core and the floating mold core, the purpose of quick demolding is achieved, and the demolding efficiency and the product yield of the rubber corrugated diaphragm are improved.
Description
technical field [0001] The invention relates to the technical field of vulcanization molding dies, in particular to a vulcanization molding die and a vulcanization molding method for a rubber corrugated diaphragm used in an automobile pump. Background technique [0002] Rubber bellows diaphragms are the core components in automotive pumps. In order to ensure safety, the performance requirements of the rubber corrugated diaphragm are usually very strict, such as good reset performance, sealing performance and mechanical performance. [0003] refer to figure 1 , the corrugated rubber diaphragm to be processed in the present invention has a relatively complicated corrugated structure, which makes it difficult to demould after vulcanization and molding, and is prone to defects. Once this defective rubber bellows diaphragm is put into use, it will cause serious pump failure consequences. [0004] In order to facilitate the demoulding of the rubber corrugated diaphragm, a pneum...
