To care for the road edge stone mold, we should focus on several
important parts and parts. The function of the top out and guiding parts
is to ensure the opening and closing of the die and the top out of the
plastic parts. If any part is stuck because of the damage, it will cause
the stop of production, so it should always keep the lubrication of the
mold top needle and the guide column. It is necessary to detect the
deformation and surface damage of thimble, guide pin and so on.
With the continuous production time, the cooling channel easily
deposited scale, rust, silt and algae, which made the cooling channel
cross section smaller and the cooling channel narrowed, greatly reducing
the heat exchange rate between the cooling solution and the railway
highway cover die, and increasing the production cost of the enterprise.
Therefore, the clear principle of the flow passage should be paid
attention to. In terms of heating and control system maintenance, it is
very important to prevent production failures.
After a production cycle is completed, a professional anti rust oil
is applied to the working surface, motion, and guide parts of the mold.
The protection of the elastic strength of the gear, the bearing parts
of the rack and the spring die should be emphasized so as to ensure that
it is always in the best working condition.
