A hole-drilling device for the turntable of a shoe sole forming machine

Abstract

The invention relates to a hole forming device for a shoe sole forming machine rotary disc, and relates to the technical field of shoe machine rotary disc production equipment. The hole forming devicecomprises a base, and a conveying mechanism, wherein a fixing mechanism and a hole forming mechanism are sequentially arranged on the base; the conveying mechanism comprises a sliding way formed in the upper end of the base, and a sliding base is arranged in the sliding way in a sliding mode; a first screw rod is rotationally connected in the sliding way, and the lower end of the sliding base isin threaded connection with the first screw rod; the upper end of the sliding base is rotationally connected with a circular truncated cone, and a limiting base is arranged on the circular truncated cone; a first air cylinder is mounted on the circular truncated cone, and an output shaft of the first air cylinder is fixedly connected with the limiting base; and a containing groove allowing the outer side wall of the rotary disc to be inserted is formed in the limiting base. The hole forming mechanism comprises an operation table arranged on the base in a sliding mode, a rotary hole base is arranged on the operation table, and a rotating rod is rotationally connected in the rotary hole base. The hole forming device has the effects of being high in automation degree and capable of improvingthe hole forming efficiency of the rotary disc.

Description

technical field [0001] The invention relates to the technical field of production equipment for shoe machine turntables, in particular to a hole-drilling device for shoe sole forming machine turntables. Background technique [0002] At present, the working principle of the shoe sole molding machine is similar to that of the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plastic that has been plasticized in a molten state (ie, viscous flow state) into the closed cavity. , the process of obtaining the sole after curing and shaping. [0003] In the prior art, the Chinese patent whose application publication number is CN107538774A discloses a fully automatic shoe sole molding machine, which includes an organic body, a turntable that is arranged on the body and has a number of sole injection molds evenly distributed thereon, and sequentially arranged along the outer peripheral surface of the turntable. Forming injection station, mold lock ...

Problems solved by technology

[0004] When it is necessary to open mounting holes on the turntable in the existing market, it is usually first to manually mark the position of the installation holes on the turntable, and then place the turntable on a special base. The matching limit groove is used to limit and fix the turntable by placing the turntable in the limit groove; finally, manually use table rotation or electric rotation to open holes at the mark; but when the maximum diameter of the turntable to be processed changes , the limit groove on the base will not be able to limit and fix the turntables with different diameters, and it will not be possible to limit and fix the turntables with different diameters, which has certain limitations; moreover, the above processing method consumes a lot of manpower and is not Conducive to mass production in factories
