Abstract

The gas auxiliary core-pulling mechanism of processing PP flared pipe fitting mould, including the core being arranged on mould core pulling slide block, the PP flared pipe fitting of molding is had outside core, the head of core installs plug, is shaped with air inlet in described core, installs gating insert between core and plug, gating insert arranges tunnel gate, arranging runner of hiding in plug, arrange air inlet duct and air inlet gap between gating insert and core, air inlet duct is connected with air inlet with air inlet gap.When loosing core, core-pulling slide block drives core to loose core, simultaneously, high pressure gas blows into from air inlet, gas be blown into along air inlet, air inlet duct and air inlet gap by flared pipe fitting and core edema caused by disorder of QI from, alleviate the cladding power of PP flared pipe fitting, make core produce minimum friction with product, so that product do not draw white, do not pull, it is ensured that product quality.

Description

The gas auxiliary core-pulling mechanism of processing PP flared pipe fitting mould
Technical field
The present invention relates to a kind of gas auxiliary core-pulling mechanism processing PP flared pipe fitting mould, belong to mould of plastics field.
Background technology
The plastic flared tube being made up of PP material, when core is loosed core, traditional method is all to do core-pulling mechanism to reach, at product two, balance of loosing core, but shortcoming to be production efficiency slow, mould volume is big, and injection machine used also increases, and cost is high.In order to reduce mould volume, make mould be suitable for middle-size and small-size injection machine and produce, at present, when flared pipe fitting core is loosed core, the monolateral pulled core structure of general employing.But, in actual production, owing to PP material flexibility is big, cladding power is strong, monolateral when loosing core frictional force big, easily make the enlarging position of pipe fitting draw white and pull, affect product quality, even scrap.
Summary of the invention
The invention aims to overcome the shortcoming of prior art, there is provided a kind of when core is loosed core, use the monolateral auxiliary structure of aerating of loosing core, reduce core to rub with product (particularly enlarging position), product is made to be difficult to pull, ensure quality, improve the gas auxiliary core-pulling mechanism of the processing PP flared pipe fitting mould of yield rate.
The technical scheme of the gas auxiliary core-pulling mechanism that the present invention processes PP flared pipe fitting mould is: include the core being arranged on mould core pulling slide block, the PP flared pipe fitting of injection mo(u)lding is had outside core, the head of core installs plug, it is characterized in that described core is shaped with air inlet, gating insert is installed between core and plug, gating insert arranges tunnel gate, plug arranges runner of hiding, arranging air inlet duct and air inlet gap between gating insert and core, air inlet duct is connected with air inlet with air inlet gap.
The invention discloses a kind of gas auxiliary core-pulling mechanism processing PP flared pipe fitting mould, it is mainly characterized by arranging air inlet in core, the head of core arranges gating insert, and air inlet duct and air inlet gap are set between gating insert and core, when loosing core, core-pulling slide block is driven to slide by power, core-pulling slide block drives core to loose core, simultaneously, high pressure gas blows into from air inlet, gas is along air inlet, air inlet duct and air inlet gap be blown into by flared pipe fitting and core edema caused by disorder of QI from, alleviate the cladding power of PP flared pipe fitting, core is made to produce minimum friction with product, so that product does not draw white, do not pull, ensure product quality, improve yield rate, reduce waste, cost-effective.
The gas auxiliary core-pulling mechanism of the processing PP flared pipe fitting mould of the present invention, the wide K of described air inlet duct can be 0.3-0.5mm, and beneficially gas enters.Spacing L in described air inlet gap can be 0.01-0.02mm, does not affect product injection.Described gating insert is installed anti-rotational alignment pin, prevents gating insert from rotating.Described plug is arranged on core head through screw, firmly installs.
Accompanying drawing explanation
Fig. 1 is the PP flared pipe fitting mould structure schematic diagram of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to schematic cross-section;
Fig. 3 is partial enlarged drawing at the B of Fig. 1.
Detailed description of the invention
The present invention relates to a kind of gas auxiliary core-pulling mechanism processing PP flared pipe fitting mould, as shown in Figure 1-Figure 3, including the core 2 being arranged on mould core pulling slide block 1, the PP flared pipe fitting 3 of injection mo(u)lding is had outside core, the head of core 2 installs plug 4, described core 2 is shaped with air inlet 6, gating insert 5 is installed between core 2 and plug 4, gating insert arranges tunnel gate 11, plug 4 arranges runner 12 of hiding, arranging air inlet duct 7 and air inlet gap 8 between gating insert 5 and core 2, air inlet duct 7 is connected with air inlet 6 with air inlet gap 8.This programme be mainly characterized by arranging air inlet 6 in core 2, the head of core 2 arranges gating insert 5, and air inlet duct 7 and air inlet gap 8 are set between gating insert 5 and core 2, when loosing core, core-pulling slide block 1 is driven to slide by power, core-pulling slide block 1 drives core 2 to loose core, simultaneously, high pressure gas blows into from air inlet 6, gas is along air inlet, air inlet duct and air inlet gap be blown into by flared pipe fitting 3 and core edema caused by disorder of QI from, alleviate the cladding power of PP flared pipe fitting, core is made to produce minimum friction with product, so that product does not draw white, do not pull, ensure product quality, improve yield rate, reduce waste, cost-effective.The wide K of described air inlet duct 7 can be 0.3-0.5mm, and beneficially gas enters.Spacing L in described air inlet gap 8 can be 0.01-0.02mm, does not affect product injection.Described gating insert 5 is installed anti-rotational alignment pin 9, prevents gating insert from rotating.Described plug 4 is arranged on core 2 head through screw 10, firmly installs.
