Description

Automatic mold opening machine and method for JC type elastic side bearing body mold

Technical Field

The invention belongs to the field of die manufacturing, and relates to automatic die opening machine and automatic die opening method for JC type elastic side bearing body dies, which relate to automatic operation of a die opening part of an elastic side bearing body requiring vulcanized rubber in the production process.

Background

Vulcanization is a chemical reaction, also referred to as curing, crosslinking, and generally refers to the process of reacting double bonds in rubber or other elastomeric materials with a vulcanizing agent to form a crosslinked structure. This reaction can improve the strength, abrasion resistance, aging resistance and chemical resistance of the rubber, thereby making it more suitable for use in manufacturing various products such as tires, seals, rubber tubes, etc. The vulcanized rubber piece becomes stronger, better in elasticity and stronger in wear resistance, and also has better high-temperature resistance, low-temperature resistance and chemical corrosion resistance. These properties enable the vulcanized rubber to be used in a variety of harsh environments and have a longer service life. For example, vulcanized rubber articles, such as tires, seals, rubber tubes, etc., are better able to withstand the friction and vibration of the vehicle during operation, thereby extending their life. The JC type elastic side bearing body is a key part loaded on a K2 type bogie, a K6 type bogie and other high-speed running speed-up trucks. The JC type elastic side bearing body plays a role in controlling the running stability of the vehicle in the whole loading process, and mainly aims at the force and the longitudinal force in the vertical direction during working, so that the rigidity and the elasticity of parts are extremely high in the production and manufacturing process of the elastic side bearing body. The JC type elastic side bearing body is a vulcanized rubber component, and the pressure maintaining and cooling time is long after vulcanization, so that the time consumption is extremely long in the production process.

However, the dies for JC type elastic side bearing body production are all multi-layer die bodies, and after vulcanization and cooling are completed, the die body has the following defects: at present, aiming at the die sinking operation of a multilayer die, most manufacturers still select a pure manual operation mode to finish the die sinking operation, and the operation method has the advantages of low working efficiency, complicated operation process, high working strength of workers and high labor cost of enterprise production, and can possibly damage products in the die sinking operation process. In summary, an automatic mold opening machine capable of orderly completing sequential mold opening tasks of a multi-layer mold is designed for mold opening parts in the production process of the elastic side bearing body, so that the production efficiency of the JC type elastic side bearing body and the automation level of mold opening operation are improved, the working intensity of workers is reduced, the labor cost is reduced, unnecessary human loss is avoided, and the technical problem to be solved in the manufacturing process of the elastic side bearing body is solved.

step 1E, under the drive of a rodless cylinder 3-9, the mold opening manipulator 4 translates to the reclaimed material frame placing platform 1-2 along a guide rail III 3-4; when the material reaches the position above the first material frame 5 placed on the recycling platform, the mold opening manipulator 4 places the top mold 9-1 into the first material frame, and the classification recycling of the top mold 9-1 is completed;

step 2, stripping the whole JC type elastic side bearing body and the middle layer die from the bottom die 9-4, and recovering the bottom die 9-4:

step 2A, the die opening manipulator 4 returns to the upper part of the JC elastic side bearing body, and simultaneously, the clamping cylinder claw I6-1 and the clamping cylinder claw II 6-12 rotate anticlockwise by 90 degrees under the action of the clamping cylinder I6-2 and the clamping cylinder II 6-11 to release the fixation of the cylinder claw to the middle layer die; wherein the middle layer mould comprises a pair of long side moulds 9-2 and a pair of short side moulds 9-3;
