The operating procedures of the core shooting machine are as follows: 1. Before the operation of the core shooting machine
, remove obstacles that hinder the normal operation of the core shooting machine equipment.
Lubricate the equipment according to the provisions of the lubrication card.
. Check whether the fasteners in key parts of the core shooting machine equipment are tight. If they are loose, they must be tightened.
Check whether all door handles are in the rest position.
, unscrew the compressed air valve, and conduct a no-load test run on the core shooting machine equipment. During this process, it is necessary to check whether the mechanism operates normally and whether the pipelines of each valve are leaking.
2. During the operation of the core shooting machine
After the core shooting machine is started, the operator is not allowed to leave his job without authorization. He should concentrate his mind and operate carefully according to the process procedures, but he is not allowed to operate two machines at the same time. A thwarting door.
. Always pay attention to the operation of the core shooting machine. If there is poor lubrication, loose fasteners, damaged parts, leakage in the pipeline, or other abnormal phenomena, stop the machine immediately and notify maintenance personnel if necessary. repair.
During the production process, if it is found that the core shooting machine is unable to shock, compact, turn, or clamp, the maintenance personnel should be notified to check and repair.
Always keep the shock piston working in a lubricated state, regularly blow off the sand on the piston, and then spray it with lubricating oil.
When lifting the sand box, do not allow the sand box to collide with the model or door handle to avoid damage to the model or malfunction.
During the production process, the sand accumulation on and around the core shooting machine should be frequently removed to prevent sand from entering the cylinder.
If an accident occurs in the core shooting machine, the operation of the equipment should be stopped immediately, stay on site, and report to the relevant departments for inspection, analysis, and processing.
3. After the work is completed
Clean the site, clean up the sand accumulation on and around the core shooting machine, and wipe down the equipment.
. Place all door handles of the core shooting machine in the rest position and turn off the compressed air valve.
No sand boxes or other objects shall be parked on or around the core shooting machine equipment.
The working principle of the core shooting machine is to inject the core sand mixture with liquid or solid thermosetting resin as a binder into the heated core box. The sand core will quickly harden to a certain thickness in the hot core box ( About ~), take it out and get a high-quality finished sand core with smooth surface and accurate size.
Compared with ordinary core shooting machines, the hot core box core shooting machine has the following advantages
The working process of the hot core box core shooting machine is high in production efficiency. Sand filling and compaction are completed at the same time, and the hot core box is immediately For medium hardening, one cycle only takes ten to tens of seconds to produce sand cores for casting. The sand core is of good quality and can be used to produce sand cores of any complexity, with precise dimensions and smooth surface, thus reducing the machining allowance of castings.
It can save a lot of auxiliary equipment and tools for core making, such as core baking furnace, dryer, core bone, wax wire, etc.
It reduces labor intensity, is flexible and light to operate, and is easy to master. It uses electric heating, the temperature can be automatically controlled, and the working place is easy to keep clean, creating conditions for the mechanization and automation of the core making process.
If equipped with a gas generation system, this machine can meet the requirements for cold core box core making.
