How to carry out the routine maintenance of injection mold?
(1) inspection before use.
Before the injection mold is used, check with the process file to see whether the mold specifications and models used are consistent with the process documents.
Check whether the equipment used is in accordance with the injection mold and whether the mold is in good condition.
The operator should have a detailed understanding of the use performance, structural characteristics and operating principle of the mould, and be familiar with the operation method.
(2) inspection during use.
The operation site must be clean, the tools should be neatly arranged, the mold should have no foreign body, the road should be free.
In the process of using the injection mould, it is necessary to observe the operating rules to prevent disorderly release, mess and collision.
The first few products of the mold production should be carefully inspected according to the drawing, and then the production can be officially produced.
In the work, it is necessary to check the working conditions of the mold at any time, and the abnormal phenomena should be maintained at any time.
Pay attention to the lubrication of the mold at any time, and lubricate the moving parts of the mould regularly.
(3) inspection after use.
After use, the mould is removed from the injection molding machine according to the operating procedure, and it is forbidden to disassemble and disassemble the mould, so as to avoid damaging the mold.
The hoisting of the mould should be safe, light, slow, remove the mould, wipe clean, and lubricate it.
Check the technical status of the mold after use, restore it to normal working condition, and send it to the designated place for storage.
(4) maintenance of cooling watercourse.
In injection mold, the cooling water channel is indispensable, and the work of cooling watercourse is very important to the quality of plastic parts.The surface of the cooling water channel is easy to deposit scale, rust, sludge and algae, blocking waterways, and greatly reduce the heat exchange between the mould and, therefore, timely inspection and maintenance is very necessary.
A blocked inspection.Whether it is blocked or not, it can be understood by the measurement of the cooling water flow rate, and the cooling water can reflect the blockage of the water channel through the pressure drop of the mold.
The blockage of the blockage.After the cooling water channel is blocked, it must be cleared in time. Because the injection mold is inconvenient to be opened, the cleaning can only be carried out without disassembly.Dredge, cleaning agents are available, and the cleaner to intense pressure from entering the cooling water channel, in this way, accumulated material such as dirt and under the effect of scouring force and chemical etching from the channel wall falls off, so as to achieve the aim of dredging.
