Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tin material processing, in particular to an automatic demoulding mechanism for tin material forming. Background Art
[0002] In the prior art, tin wire is typically produced by stretching. This involves first casting molten tin into bars or blocks, then stretching these larger diameter bars or blocks through a wire drawing machine into tin wire of varying specifications. Currently, the formed tin is demolded using a foot pedal, which ejects the tin from the mold cavity via a push rod at the other end. However, this pedal-based demolding method can be challenging for different operators, with some operators experiencing difficulty with the pedal due to insufficient strength. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide an automatic demoulding mechanism for tin material forming with high automation degree and labor-saving demoulding.
[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: an automatic demolding mechanism for tin material forming, comprising a mold table, a base, a rail car, a first electric push rod, a second electric push rod, a connecting rod, a limit block, a push plate, a guide sleeve, a fixed sleeve, a movable sleeve, a first guide rod, a spring, a limit switch, a second guide rod, a tension spring and a control module. The mold table is fixedly installed on the base, and a mold cavity is arranged in a linear array on the mold table. A sealing head is embedded in the bottom of the mold cavity for sliding sealing. A linear guide rail is fixedly installed on the top of the base, and the wheels of the rail car are placed on the linear guide rail. The first electric push rod is fixedly installed on the rail car, and the first electric push rod is fixedly installed on the top of the rail car. The fixed sleeve is fixedly installed on the bottom of the mold table, the guide sleeve is fixedly sleeved on the fixed sleeve, and the movable sleeve is slidably sleeved on the guide sleeve. Four first guide rods are distributed in a ring, and their lower ends are fixedly installed on the movable sleeve. The locking mechanism is fixedly mounted on the cam frame, and the locking mechanism is secured on a central portion of the cam frame and is secured on a central portion of the cam frame.
[0005] Preferably, the inclination of the inclined surface structure provided between the contact surface of the limiting block and the push plate is 30°-50°.
[0006] Preferably, two protrusions are provided on the bottom surface of the rail vehicle, and a slot cooperating with the limit block is formed between the two protrusions.
[0007] Preferably, a guide block is fixedly mounted on the right end of the transverse groove, and the left end of the connecting rod is slidably mounted in the guide block.
[0008] Compared with the existing technology, the benefits of the present invention are: the demoulding mechanism uses electric propulsion to push the formed milling groove upward out of the mold cavity to complete demoulding, which has a high degree of automation and saves more effort for operators to process the formed tin materials. The support of the rail car by the limit block prevents the wheels of the rail car from being subjected to the reaction force during demoulding, prevents the wheels and their axles from being squeezed and deformed, and extends the service life of the rail car.
