Abstract
The auxiliary core-pulling mechanism of gas of processing PP flared pipe fitting mould, comprise the core being arranged on mould core pulling slide block, core has the PP flared pipe fitting of moulding outward, the head of core is installed plug, in described core, is shaped with air admission hole, between core and plug, gating insert is installed, tunnel gate is set in gating insert, the runner of hiding is set in plug, air inlet duct and air inlet gap are set between gating insert and core, air inlet duct and air inlet gap are connected with air admission hole.While loosing core, core-pulling slide block drives core to loose core, simultaneously, high pressure gas blows into from air admission hole, gas is blown into flared pipe fitting is separated with core gas along air admission hole, air inlet duct and air inlet gap, alleviates the coated power of PP flared pipe fitting, makes core and product produce minimum friction, thereby make product do not draw white, do not pull, ensure product quality.
Description
Technical field
The utility model relates to a kind of auxiliary core-pulling mechanism of gas of the PP of processing flared pipe fitting mould, belongs to mould of plastics field.
Background technology
The plastic flared tube of being made by PP material, in the time that core is loosed core, traditional method is all to do core-pulling mechanism at product two to reach the balance of loosing core, but that shortcoming is production efficiency is slow, and mould volume is large, and injection machine used also increases, and cost is high.In order to dwindle mould volume, make mould be applicable to middle-size and small-size injection machine and produce, at present, in the time that flared pipe fitting core is loosed core, generally adopt monolateral pulled core structure.But in actual production, because PP material flexibility is large, coated power is strong, when monolateral loosing core, frictional force is large, easily makes the enlarging position of pipe fitting draw white and pull, and affects product quality, even scraps.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, provide a kind of in the time that core is loosed core, adopt the auxiliary structure of the monolateral aerating of loosing core, reduce core and product (particularly enlarging position) friction, make product be difficult for pulling, ensure the quality of products, improve the auxiliary core-pulling mechanism of gas of the processing PP flared pipe fitting mould of yield rate.
The technical scheme of the auxiliary core-pulling mechanism of gas of the utility model processing PP flared pipe fitting mould is: comprise the core being arranged on mould core pulling slide block, core has the PP flared pipe fitting of injection mo(u)lding outward, the head of core is installed plug, it is characterized in that being shaped with air admission hole in described core, between core and plug, gating insert is installed, tunnel gate is set in gating insert, the runner of hiding is set in plug, air inlet duct and air inlet gap are set between gating insert and core, and air inlet duct and air inlet gap are connected with air admission hole.
The utility model discloses a kind of auxiliary core-pulling mechanism of gas of the PP of processing flared pipe fitting mould, main feature is that air admission hole is set in core, the head of core arranges gating insert, and air inlet duct and air inlet gap are set between gating insert and core, while loosing core, drive core-pulling slide block to slide by power, core-pulling slide block drives core to loose core, simultaneously, high pressure gas blows into from air admission hole, gas is along air admission hole, air inlet duct is blown into flared pipe fitting is separated with core gas with air inlet gap, alleviate the coated power of PP flared pipe fitting, make core and product produce minimum friction, thereby it is white that product is not drawn, do not pull, ensure product quality, improve yield rate, reduce waste, save cost.
The auxiliary core-pulling mechanism of gas of processing PP flared pipe fitting mould of the present utility model, the wide K of described air inlet duct can be 0.3-0.5mm, is beneficial to gas and enters.The spacing L in described air inlet gap can be 0.01-0.02mm, does not affect product injection moulding.Anti-rotation alignment pin is installed in described gating insert, is prevented that gating insert from rotating.Described plug is arranged on core head through screw, installs firmly.
