Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are all within the protection scope of the present utility model.
An exhaust self-locking device for a rubber product vulcanization mold comprises an exhaust core sleeve 2, an exhaust core 3, a second adjusting spring 5, an exhaust valve body 6 and a plug 7; the exhaust valve body 6 is inserted into an exhaust hole of the die 1 in a matching manner, a through hole 8 is formed in the middle of the exhaust valve body 6 along the axial direction of the exhaust valve body, the through hole 8 is communicated with the air outlet end of the die cavity, and an exhaust core sleeve 2, an exhaust core 3, an adjusting spring II 5 and a plug 7 are arranged in the through hole 8; the exhaust core sleeve 2 is fixed at the air inlet end of the through hole 8, an exhaust core 3 is inserted in the exhaust core sleeve 2 in a clearance fit sliding manner, the exhaust core sleeve 2 is sleeved on the outer side of the exhaust core 3 in a ring manner, and a gas channel is reserved between the exhaust core sleeve 2 and the exhaust core sleeve; the exhaust core sleeve 2 is of a flange structure and is used for connecting the exhaust core 3 with the exhaust valve body 6 and limiting the position of the exhaust core 3, the air inlet end of the exhaust core 3 and the air inlet end of the exhaust core sleeve 2 are arranged in a sealing fit manner through a wedge surface, the air outlet end of the exhaust core 3 is fixedly connected with one end of the second adjusting spring 5, the other end of the second adjusting spring 5 is fixedly connected with the plug 7, the plug 7 is screwed with the air outlet end of the through hole 8, and the axial position of the plug 7 in the exhaust valve body 6 can be adjusted through the screwed connection; the middle part of the plug 7 is provided with a first air outlet hole 9 communicated with the through hole 8.
The outside cover of exhaust core 3 is equipped with adjusting spring one 4, the one end of adjusting spring one 4 and the end fixed connection of the end of giving vent to anger of exhaust core 3, the other end and the exhaust core cover 2 fixed connection of adjusting spring one 4, adjusting spring one 4 is used for balancing the elasticity of adjusting spring two 5, avoids adjusting spring two 5 elasticity too big to lead to exhaust core 3 to close.
