Abstract

The application discloses emergency exit for injection moulding device, including the emergency exit, the emergency exit is other to be equipped with the travel switch that a plurality of monitoring emergency exits were opened, and all travel switch electricity are connected to the controlgear and open the controller that stops, be equipped with emergency stop switch on the controller, its characterized in that, be equipped with the electrically operated gate backing pin on the route of closing of emergency exit, be equipped with control on the controller the electrically operated gate backing pin's door backing pin button. This application advantage lies in, has set up the door shield round pin that can control to stretch out on the route of closing of emergency exit, prevents that the emergency exit from being closed by accident, has improved operating personnel's security greatly.

Description

Safety door for injection molding equipment

Technical Field

The application relates to a safety door for injection molding equipment, and relates to the technical field of safety protection of injection molding equipment.

Background

Common injection molding plants, such as plastic injection molding machines, rubber injection molding machines, die casting machines, etc., have a safety door protection of 3 different classes according to the national standard GB22530, wherein the closing operation side safety door must comply with type iii protection. Fig. 1 and 2 are schematic diagrams showing the structure of the existing safety door, three travel switches, namely a travel switch 2, a travel switch 3 and a travel switch 4, are provided for safety protection when the safety door 1 is opened, signals of the three travel switches are all connected with a controller 7, the three travel switches are arranged at different positions of the safety door 1, whether the safety door 1 is opened or not is monitored from different positions, monitoring redundancy is improved, and monitoring cannot be affected due to partial failure; the emergency stop switch 5 is used for emergency stop of the machine operation when any accident occurs. When the safety door 1 is opened, the travel switch 2, the travel switch 3 and the travel switch 4 all send signals to the controller 7, the machine stops moving, and an operator can enter the machine to perform operations such as maintenance and the like.

Although the safety door structure meets the type III protection, the safety door structure still has the potential of being unsafe, and if a person operates in the machine, the safety door is closed accidentally, so that a great potential safety hazard exists.

SUMMERY OF THE UTILITY MODEL

The technical problem that this application will be solved is how to prevent that emergency exit from being closed by accident.

In order to solve the technical problem, the technical scheme of this application provides an emergency exit for injection moulding device, including the emergency exit, the other travel switch that is equipped with a plurality of monitoring emergency exits and opens of emergency exit, and all travel switch electricity are connected to the controlgear and are stopped the controller that stops, be equipped with emergency stop switch on the controller, its characterized in that, be equipped with the electrically operated gate stop pin on the route of closing of emergency exit, be equipped with control on the controller the door shelves round pin button of electrically operated gate stop pin.

This application advantage lies in, has set up the door shield round pin that can control to stretch out on the route of closing of emergency exit, prevents that the emergency exit from being closed by accident, has improved operating personnel's security greatly.

Detailed Description

In order to make the present application more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Examples

The safety door for the injection molding equipment is provided in the embodiment, and the safety door is prevented from being accidentally closed, referring to fig. 3 and 4, the safety door structurally comprises a safety door 1, a travel switch 2, a travel switch 3, a travel switch 4, an emergency stop button 5, a door stop pin button 6, a controller 7 and an electric door stop pin 8.

A plurality of travel switches are mounted at different positions of the safety door 1 and used for monitoring the opening state of the safety door 1, and signals of all the travel switches are connected and transmitted to the controller 7; set up electrically operated gate stop pin 8 on emergency exit 1's the route of closing, electrically operated gate stop pin 8 electricity is connected to door stop pin button 6, by door stop pin button 6 control electrically operated gate stop pin 8, after emergency exit 1 opens, a plurality of travel switch can signals for controller 7, controller 7 keeps injection moulding device stop motion, and simultaneously, electrically operated gate stop pin 8 that is located emergency exit 1 on closing the route promotes the door stop pin and stretches out, block closing of emergency exit 1, personnel are all in safe state in the inside operation of machine and maintenance, at this moment, the emergency exit that any accidental or other factors lead to is closed, all can be blockked by the door stop pin, really ensure personal safety.

Personnel leave the equipment, under the condition of guaranteeing safety, firstly through door shelves round pin button 6 control electrically operated door stop pin 8 retrieve the door stop pin, then close emergency exit 1, emergency exit 1 closes the back, and travel switch 2, travel switch 3, travel switch 4 also can send the signal to controller 7, and the machine can get into running state.

Claims
