Insert automatic falling device capable of avoiding secondary demolding

Abstract

The invention relates to the technical field of secondary mold release of molds, and discloses an insert automatic falling device capable of avoiding secondary demolding. The insert automatic fallingdevice comprises a base, a support, a mounting frame, a supporting table, a telescopic rod, an electromagnetic valve, a telescopic air cylinder, an air source triple piece, a control part, a pressinghead and a protruding part, wherein a fixing block is fixedly connected to the side wall of the mounting frame, a first groove corresponding to the fixing block is formed in the side wall of the base,a cavity is formed in the base, a first rolling bearing is embedded on the left side of the cavity, a rotating shaft is fixedly connected in the first rolling bearing, one end of the rotating shaft is fixedly connected with a first bevel gear, and the upper side and the lower side of the first bevel gear are meshed with second bevel gears respectively. According to the insert automatic falling device capable of avoiding secondary demolding, the mounting frame can be conveniently fixed with the base, so that the problem that the insert falls off due to looseness of bolts can be effectively avoided, dust in the air can be effectively filtered, and meanwhile, a dust screen can be conveniently disassembled and assembled.

Description

technical field [0001] The invention relates to the technical field of secondary demoulding of molds, in particular to an automatic dropping device for inserts that avoids secondary demoulding. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine. Due to some restrictions, it cannot be demoulded directly in the mold, and a secondary demoulding outside the mold is required. [0003] After searching, the Chinese patent authorization number is CN105500607B patent, which discloses the automatic shedding device of mold inserts, including base, bracket, mounting frame, support table, telescopic rod, solenoid valve...

AI Technical Summary

Problems solved by technology

The mold insert automatic fall-off device in the above-mentioned patent has the following disadvantages: in this patent, when the mounting frame is connected with the base, it is mostly connected by using bolts, and the driving force generated by the telescopic cylinder is easy to be affected by the bolt connection. The impact of the bolts, causing the bolts to loosen, thereby affecting the fall-off of the insert
