Description
Technical Field
The utility model relates to the technical field of core pulling machinery, in particular to a large-scale core pulling machinery backstop mechanism.
Background
The cavity die tunnel is loose core, the front end injection molding pressure is high, and a mechanical limiting block is additionally arranged at the rear end of the loose core, so that the loose core is ensured not to retreat when bearing the injection molding pressure.
The diameter of the oil cylinder is increased by conventional design, so that the ejection force of the oil cylinder is larger than the injection molding pressure, or a large self-locking oil cylinder is used, and the cost and the space occupation are high.
Disclosure of utility model
Aiming at the defects of the prior art, the utility model provides a large-scale loose core mechanical retaining mechanism, which solves the problems in the background art. In order to achieve the above purpose, the utility model is realized by the following technical scheme: the large-scale loose core mechanical retaining mechanism comprises an injection molding main body and an oil cylinder, wherein a mold core is slidably connected in the injection molding main body, a sliding groove is formed in the injection molding main body, a limiting block is slidably connected in the sliding groove, a movable block is arranged in the mold core, and a limiting groove is formed in the outer surface of the movable block.
Preferably, the size of one end of the limiting block, which is close to the limiting groove, is the same as the size of the limiting groove.
Preferably, the limiting block is located between the sliding groove and the mold core.
Preferably, an oil cylinder is fixedly connected to one end, far away from the inner part of the mold core, of the movable block.
The utility model provides a large-scale loose core mechanical stop mechanism. The beneficial effects are as follows:
The utility model discloses a cooperation between mold core, stopper, spout, movable block and the spacing groove utilizes the power of hydro-cylinder to support the mold core when the stopper is not in spacing inslot portion, and then ensures that the mold core can not take place the displacement at the in-process of work, to prior art, simple structure, processing is convenient, dismouting, maintenance are convenient, manufacturing and use are with low costs, and stable performance, work efficiency is high, and the security is high.
