Injection molding machine safety door adopting linear ball bearing

Abstract

The invention discloses an injection molding machine safety door adopting a linear ball bearing. The injection molding machine safety door comprises a base, a left side plate and a right side plate are fixedly arranged at the edge of the base, an adjusting door plate is slidably arranged between the left side plate and the right side plate, and a horizontal sliding rod is arranged on the side portion of the base. A mounting plate is arranged on the surface of the inner side of the adjusting door plate, the linear ball bearing matched with the sliding rod is detachably arranged on the mountingplate, and a switch for controlling an injection molding machine mold to stop moving and an adjusting structure for controlling the switch are arranged on the base. The adjusting structure comprises apress rod connected with the switch, a connecting rod is arranged at the end, facing the outer side of the base, of the press rod, and idler wheels are arranged at the end, back onto the press rod, of the connecting rod. A supporting plate capable of abutting against the idler wheels is arranged on the adjusting door plate and abuts against the idler wheels to enable the mold to stop moving. Theinjection molding machine safety door adopting the linear ball bearing has the advantages that moving is smooth and capable of saving labor, and the safety of an injection molding machine can be improved.

Description

technical field [0001] The invention relates to a safety door of an injection molding machine, in particular to a safety door of an injection molding machine using a linear ball bearing. Background technique [0002] In the prior art, the injection molding machine usually includes a fixed mold and a movable mold in use, and the fixed mold and the movable mold are usually installed on the fixed platen and the movable platen, and the driving device drives the movable platen to move toward or away from the fixed platen, thereby realizing Mold clamping and mold opening, in order to improve the safety of the injection molding machine at work, a protective door is usually installed on the front of the injection molding machine, but the existing protective door generally uses a plastic pulley structure, which has a short service life and low safety performance. Poor, when the protective door is in the open state, the movable formwork can still move, which is easy to cause safety ac...
