Shaping segment lenght≤700 millimeter of the utility model die ontology 11 so that it has the following effects that：
1. mold processing becomes simple, originally 1 meter of long mold is easily deformed, process velocity is slow, generally in process
It is all processed using grinding machine, cost is relatively high.Make short mould rear mold processing into become simplified as, the method that can be processed
Have very much, original grinding machine technique may be used, numerical control machining center can also be used, wire cutting technology etc. can also be used
Deng.2. product stripping resistance becomes smaller, product content of glass fiber can improve, and be set in mold ditch angle and plane to greatly reduce
The case where fat sticking to mould, the raising of fiber can improve the intensity of product, and the raising of fiber content can reduce resin usage amount, drop
The cost of material of low product.Ejection resistance is small, because the internal stress that ejection resistance generates is mitigated, the straightness after product depanning
More stablize, is conducive to the raising of product qualification rate.Ejection resistance is small, and die wear situation slows down, and service life can carry significantly
It is high.The small energy consumption for advantageously reducing equipment of ejection resistance, reduces the maintenance costs of equipment.3. can also be by original 1 meter
The mold of long left and right processes, and use of cutting in half substantially reduces die manufacturing cost in this way.
The above are merely preferred embodiments of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this
The protection domain of utility model.
