Description

A kind of plastic mould
Technical field
The utility model relates to a kind of plastic mould.
Background technology
Existing plastic mould, does mold insert 2 in most mould 1, and dismounting mold insert 2 is the things that must do.Mold insert 2 of a great variety, and different, a lot of mold insert 2 end is very sharp, as shown in Figures 1 and 2, mold insert 2 needs to pound out from the front of mould 1, and the tip of mold insert 2 or flat end are easy to be struck and collapse or knock off, this practice is easy to damage mold insert 2, but this phenomenon often occurs.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, plastic mould that flexible operation, cost of manufacture are low and method of operating thereof, to overcome weak point of the prior art.
By a kind of plastic mould that this object designs, comprise mould frame and die, this die is provided with outstanding mold insert, its architectural feature die is provided with the locating hole installing mold insert, and the bottom of mold insert is provided with pilot hole.
Further, the end of described mold insert is narrow or flat.
Further, described mold insert connects with base, and pilot hole is arranged on base, and mold insert is embedded in locating hole, and base is arranged in locating hole.
Further, an end section of described locating hole is little, and the other end cross section of locating hole is large.
Further, be provided with positive stop lug boss in described locating hole, base is provided with positioning boss, positioning boss is crimped on positive stop lug boss.
Further, the lateral cross section of described mold insert is less than the lateral cross section of base.
Further, described mold insert and base are wholely set.
Further, the method for operating of plastic mould is connected with base by mold insert, die outputed and only to pass and base is retained in the locating hole in die for mold insert, by the cooperation of positioning boss and positive stop lug boss, guarantees the installation site of mold insert and base; When after injection moulding end-of-job, the band long bolt of quill is connected with the pilot hole of base, then, make long bolt drive mold insert and base to exit die by impact quill.
The utility model is provided with the locating hole installing mold insert on die, and the bottom of mold insert is provided with pilot hole; Further, mold insert connects with base, and pilot hole is arranged on base, and mold insert is embedded in locating hole, and base is arranged in locating hole; Thus be that mold insert and base create favourable condition from the bottom pull-out of die.
The utility model is when dismantling mold insert and base, and stress point during dismounting, by the narrow of original mold insert or flat end, changes into the base that lateral cross section is much larger, thus improve force-bearing situation, thus also can not damage mold insert, extend the service life of mold insert, reduce cost.
The utility model has simple and reasonable, flexible operation and the low feature of cost of manufacture.
