Plate alignment pin is interference fitted with cope plate respectively；
Go up and middle Template Location guide is provided with the outside of middle template, middle template mould on middle template core rod and first on 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；
Middle template core rod forms injecting glue cylinder with lower mold core on second, and middle template core rod is also formed into glue 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.
The utility model has the following advantages that：
Air-valve guide-bar oil seal mould of the present utility model, note longer to solve injecting glue road in the presence of prior art
Glue cylinder residue biscuit is more, and sizing material wastes larger, and after mold cure, during molding, injecting glue road sizing material break away from moulds produces pair
The pulling force of product is larger, and the problems such as easily deforming the drawing crack of product spring groove, drawing, its injecting glue road is short, and residue biscuit is few, saves glue
Material, it is small to the pulling force of product because injecting glue road is short when vulcanization finishes molding, old structure can be avoided easily by product drawing crack, draw deformation
The defects of.

Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Embodiment 1
A kind of air-valve guide-bar oil seal mould, as depicted in figs. 1 and 2, including lower template 1, lower template 1 are provided with lower mold core 2,
Combination settings have a lower middle template 3 above lower template 1, and lower middle template 3 is provided with lower middle template core rod 4, above lower middle template 3
Combination settings have upper middle template 5, and upper middle template 5 is provided with first middle template core rod 7, upper middle mould on middle template core rod 6, second
Combination settings have a cope plate 8 of the pressure injection plug 9 of band above plate 5, middle template in lower mold core 2, lower middle template core rod 4, first
The middle combination of template core rod 7 forms die cavity on core rod 6 and second；Pressure injection plug 9 is provided with cope plate 8, the outside of cope plate 8 is set
Cope plate alignment pin 10 is equipped with, pressure injection plug 9 and cope plate alignment pin 10 are interference fitted with cope plate 8 respectively；Template 5 in upper
