Description
Technical field
The present invention relates to technical field of mold, and in particular to a kind of air-valve guide-bar oil seal mould and its application method.
Background technology
At present, it is many to note sizing material by hole for injecting glue using by an overall injecting glue cylinder in the production of air-valve guide-bar oil seal
The mould structure for entering die cavity realizes that it exists more, and injecting glue road is longer, and injecting glue cylinder residue biscuit is more, and sizing material wastes larger, and mould
After vulcanization is finished, during molding, influence of the pulling force that injecting glue road sizing material break away from moulds is produced to product is larger, easily by product spring
The quality problems such as groove drawing crack, drawing deformation.
The content of the invention
It is an object of the invention to provide a kind of air-valve guide-bar oil seal mould and its application method, to solve prior art
In the presence of injecting glue road it is longer, produce that waste material is more, sizing material wastes larger, and after mold cure is finished, to product during molding
Pulling force is larger, the problems such as easily deforming product drawing crack, drawing.
To achieve the above object, one aspect of the present invention provides a kind of air-valve guide-bar oil seal mould, including lower template, lower template
It is provided with lower mold core, it is characterised in that combination is provided with lower middle template above lower template, and lower middle template-setup has lower middle template
Combination is provided with middle template above core rod, lower middle template, during upper middle template-setup has on first on template core rod and second
Combination is provided with the cope plate with upper mold core above middle template core rod, upper middle template；
Lower mold core, lower middle template core rod, on first on template core rod and second in the combination of template core rod constitute die cavity；
It is provided with cope plate on the outside of pressure injection plug, cope plate and is provided with cope plate alignment pin, pressure injection plug and upper mould
Plate alignment pin is interference fitted with cope plate respectively；
Middle template mould on template core rod and first in being provided with upper on the outside of template on middle Template Location guide, second
Core is interference fitted with upper middle template respectively；
Lower middle Template Location guide, lower middle template core rod and lower middle Template Location guide point are provided with lower on the outside of template
It is not interference fitted with lower middle template；
Lower template alignment pin is provided with the outside of lower template, lower mold core and lower template alignment pin are matched somebody with somebody with lower template interference respectively
Close；
Template core rod is also constituted into glue with lower mold core during template core rod is constituted on injecting glue cylinder, second with lower mold core on second
Road, injecting glue cylinder, gum intaking passage and die cavity are sequentially communicated.
Alternatively, the quantity of die cavity is at least one.
Alternatively, each die cavity is respectively arranged with a single injecting glue cylinder.
Alternatively, each injecting glue cylinder is separately positioned on the top of its die cavity.
Another aspect of the present invention provides a kind of air-valve guide-bar oil seal mold use side as described in one aspect of the invention
Method, comprises the following steps：
Lower template, upper middle template and lower middle template are passed through into middle template on lower template alignment pin and lower middle Template Location guide
Set pin sleeve positions matched moulds；
In the injecting glue cylinder that template core rod is constituted with lower mold core during sizing material is placed on second；
Cope plate is subjected to guide-localization matched moulds by cope plate alignment pin with upper middle Template Location guide so that cope plate
Pressure injection plug aligned with injecting glue cylinder, and the ring that the sizing material in injecting glue cylinder is made up of cope plate core rod in second with lower mold core
Shape gum intaking passage injection type intracavitary.
The invention has the advantages that：
The air-valve guide-bar oil seal mould and its application method of the present invention, to solve the injecting glue road in the presence of prior art
Longer, injecting glue cylinder residue biscuit is more, after sizing material wastes larger, and mold cure is finished, during molding, injecting glue road sizing material break away from moulds
, easily deform product spring groove drawing crack, drawing the problems such as larger to the pulling force of product is produced, its injecting glue road is short, and residue biscuit is few,
Save sizing material, it is small to the pulling force of product because injecting glue road is short when vulcanization finishes molding, can avoid old structure easily by product drawing crack,
Draw the defect of deformation.
