Abstract
The utility model discloses a safety protection device of a hot box core shooter. The safety protection device of the hot box core shooter comprises a workbench of the core shooter and clamp cylinders, wherein a slide rail is arranged on the workbench of the core shooter between the two clamp cylinders; a rack is arranged on the slide rail and meshed with a fan-shaped gear at the lower end of a safety rotator; the safety rotator is mounted on a bracket at two sides of the slide rail; a retractable arm of the cylinder is fixedly connected with one end of the rack through a connecting frame; and a proximity switch mounted beside the core box slide rail is connected with the cylinder and controls the extension/retraction of the cylinder. The safety protection device has the characteristics that automatic control protection is ensured in the process of opening/closing the core box, human factors are eliminated, the safety protection effect is good, and the structure is simple.
Description
Technical field
The utility model belongs to foundry goods manufacturing hot box shoot core machine technical field, especially relates to a kind of hot box shoot core machine safety device.
Background technology
At present, casting industry generally uses 86 serial Vertical Parting Hot Box core shooters, during core shooter work, each closes box-penetrate sand-solidify-open box-get core-cleaning core box-installation loose piece-close box cycling element, open box to close box during this period of time in, need the operative employee that arm is reached in two core boxes, get core, the cleaning core box, loose piece job such as (comprising the core box maintenance) is installed, because operating personnel's arm is operated (per tour 80-120 box/1 people) repeatedly during work in two core boxes of two clamping cylinders interlock, once serious casualty accident will take place in equipment malfunction or other people maloperation; In order to prevent that industrial accident from taking place, a lot of producers require the operative employee when opening box at every turn, add the lastblock parallels in the middle of core box temporarily, play protective action.But most of operators dislike trouble, and idea of leaving things to chance, do not carry out this regulation, often cause casualty accident to take place.
Summary of the invention
The purpose of this utility model provide with the deficiency of improving prior art a kind of in open and close core box process automatic protection, eliminate human factor, security protection hot box shoot core machine safety device effective, simple in structure.
The purpose of this utility model is to realize like this, a kind of hot box shoot core machine safety device, comprise the work top of core shooter and clamp cylinder, be characterized in that clamping the middle core shooter work top of cylinder two is provided with slide rail, tooth bar is installed on the slide rail, tooth bar meshes with the sector of protection rotary body lower end, protection rotation axon is installed on the support of slide rail both sides, the telescopic arm of cylinder is installed in other the stretching near switch connection control cylinder of core box slide rail by an end of the fixedly connected tooth bar of link.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts the core shooter work top in the middle of two clamping cylinders to be provided with slide rail, tooth bar is installed on the slide rail, tooth bar meshes with the sector of protection rotary body lower end, protection rotation axon is installed on the support of slide rail both sides, the telescopic arm of cylinder is by an end of the fixedly connected tooth bar of link, be installed in and clamp other the stretching near switch connection control cylinder of cylinder, by flexible near the switch control cylinder, it is mobile at slide rail to drive tooth bar, thereby realize holding up and being put into of protection rotary body, when the protection rotary body is holded up, reach and prevent from clamping the cylinder closure, realize protection operating personnel's purpose automatically, the casualty accident of having avoided operating personnel in the prior art not place parallels and having caused, behind complete operation, the protection rotary body is transferred in the drive of cylinder, has guaranteed that the clamping cylinder can closed operate as normal; The utility model is automatic protection in open and close core box process, has eliminated human factor, and security protection is effective, and is simple in structure, the reliability height.
