Inspection of the guide parts of the hardware mold

The maintenance of hardware molds must be done carefully, patiently, step by step, and must not be blindly engaged. When repairing the mold due to failure, a material belt should be attached to facilitate the inquiry of the problem. Open the mold, compare the material belt, check the mold condition, confirm the cause of the failure, find out the problem, and then clean the mold before removing the mold. When removing the mold, the force must be uniform. For the mold structure where the discharge spring is between the fixed plate and the discharge plate and the discharge spring directly presses on the inner guide column, the disassembly of the discharge plate must ensure that the discharge plate is balanced and ejected. The tilt of the discharge plate may cause the punch in the mold to break. The clearance between the guide post and the guide sleeve, whether there are burns or wear marks, and whether the oil supply state of the mold guide is normal, should be checked. The wear of the guide and the destruction of the accuracy will reduce the accuracy of the mold, and problems will occur in various parts of the mold. Therefore, proper maintenance and regular replacement are necessary. Check the accuracy of the material guide. If the guide pin is worn out, it has lost the proper accuracy and function of the tape guide and must be replaced. Check the condition of the spring (discharge spring and ejector spring, etc.) to see if it is broken, or if it has not broken after long-term use, it has been fatigued and lost its original strength. It must be maintained and replaced regularly, otherwise it will cause damage to the mold Or production is not smooth. In the metal mold stamping production, the daily maintenance of the mold is very important, that is, daily attention to check whether the stamping machine and the mold are in a normal state, such as the refueling of the stamping oil supply guide. The inspection before the mold is put on the machine, the inspection of the blade, the confirmation of the locking of each part, etc., can avoid many unexpected accidents. Before maintenance, you must think first and then act, and earnestly record and accumulate experience. Dongguan Precision Hardware Electronics Co., Ltd. has passed ISO9001 and TS16949 certification.
