Abstract
The utility model provides a kind of plastic mould for improving offset, including preceding mould and rear mold, the die joint of the rear mold is equipped with insert, the insert is equipped with boss, the die joint of the preceding mould is equipped with the groove matched with the boss, the insert is arranged between the preceding mould, rear mold, and the boss setting is in the groove.The beneficial effects of the utility model are: by increasing insert, using the interworking between insert and preceding mould, rear mold, can effectively avoid the mismachining tolerance occurred in process and caused by product offset.
Description
Technical field
The utility model relates to mold more particularly to a kind of plastic moulds for improving offset.
Background technique
Frequently with the structure of forward and backward mould parting on current plastic mould, the mould structure of forward and backward mould parting, usually
Forward and backward mould is divided into product largest contours sectional position.With reference to attached drawing 1, including preceding mould 10, rear mold 20, for forming semicircle
Arc product 30, conventional front and back mode parting are in daily use in common structural member, and mould structure is simple, easy to process, but for
Shape is the semi arch product 30 of the bloom appearance requirement of semi arch, is just not suitable for using such forward and backward mould parting, because preceding,
Rear mold has mismachining tolerance in process.And after processing is completed, forward and backward mould also all needs to throw into bloom, mismachining tolerance and
Polishing can all cause the product profile of forward and backward mould cannot be completely the same.Currently, when there is offset in rear mold, product surrounding offset without
Method guarantees to range within smaller, causes the quality of Surface Appearance lower.
Summary of the invention
In order to solve the problems in the prior art, the utility model provides a kind of plastic mould for improving offset.
The utility model provides a kind of plastic mould for improving offset, including preceding mould and rear mold, the parting of the rear mold
Face is equipped with insert, and the insert is equipped with boss, and the die joint of the preceding mould is equipped with the groove matched with the boss,
The insert is arranged between the preceding mould, rear mold, and the boss setting is in the groove.
The die joint of the rear mold is equipped with positioning column as a further improvement of the utility model, sets in the insert
There is location hole, the positioning column is arranged in the positioning hole.
It is bolted between the insert and the rear mold as a further improvement of the utility model,.
As a further improvement of the utility model, the boss there are four and be located at the surrounding of the rear mold.
The cross section of the boss is right-angled trapezium as a further improvement of the utility model,.
As a further improvement of the utility model, the insert at the nethermost contoured surface position of shaped article with
The rear mold parting.
The insert is completely covered on the die joint of the rear mold as a further improvement of the utility model,.
The beneficial effects of the utility model are: through the above scheme, by increasing insert, utilizing insert and preceding mould, rear mold
Between interworking, can effectively avoid the mismachining tolerance occurred in process and caused by product offset.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of traditional plastic mould.
Fig. 2 is a kind of structural schematic diagram for the plastic mould for improving offset of the utility model.
Fig. 3 is the sectional view A-A of Fig. 2.
Fig. 4 is the sectional view B-B of Fig. 2.
Specific embodiment
The utility model is described in further detail for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figures 2 to 4, a kind of plastic mould improving offset, including preceding mould 1 and rear mold 2, point of the rear mold 2
Type face is equipped with insert 3, and the insert 3 is equipped with boss 31, and the die joint of the preceding mould 1 is equipped with to match with the boss 31
The groove of conjunction, the insert 3 are arranged between the preceding mould 1, rear mold 2, and the setting of boss 31 is in the groove.
As shown in Figures 2 to 4, the die joint of the rear mold 2 is equipped with positioning column 6, and the insert 3 is equipped with location hole,
In the positioning hole, the insert 3 is positioned by positioning column 6 for the setting of positioning column 6.
As shown in Figures 2 to 4, it is fastenedly connected between the insert 3 and the rear mold 2 by bolt 5.
As shown in Figures 2 to 4, the boss 31 there are four and be located at the surrounding of the rear mold 2.
As shown in Figures 2 to 4, the cross section of the boss 31 is right-angled trapezium.
As shown in Figures 2 to 4, the insert 3 at the nethermost contoured surface position of semi arch product 4 with the rear mold
2 partings.
As shown in Figures 2 to 4, the insert 3 is completely covered on the die joint of the rear mold 2.
A kind of plastic mould improving offset provided by the utility model, by increasing by one piece of insert 3, insert 3 in rear mold 2
The frame mode of rear mold 2 is fixed on using positioning column 6 and bolt 5 to realize, insert 3 is in the nethermost profile of semi arch product 4
2 parting of sectional position and rear mold, 3 surface four direction of insert increase boss 31 and the corresponding groove location fit of preceding mould 1, can be with
Insert 3 and the fixed polishing of rear mold 2 is first allowed to recycle the boss 31 of insert 3 and preceding mould 1 corresponding recessed after the completion of closing and matching polishing
Slot is fixed, then is closed with polishing.Using the interworking between insert 3 and preceding mould 1, rear mold 2, can effectively avoid in process
The mismachining tolerance of appearance and caused by product offset, the fit clearance between rear mold 1 and insert 2, to the exhaust of mold play to
Important role is closed, facilitate product walks glue.
A kind of plastic mould improving offset provided by the utility model, improves the structure of offset using mold insert 2 is increased
Mode reduces the offset of Surface Appearance bonding wire, is conducive to the quality for improving Surface Appearance, and is conducive to mold row
Gas.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
