Because of atmosphere draught-free, there is air to remain in die cavity, can cause the convex closure of the product formed out has bubble, produces stress, special
Not easily do not produce vacuum power and cause the easy drawing crack of product convex closure and height not to reach requirement, leverage product quality, shadow
Ring operating efficiency.
Utility model content
The purpose of this utility model is to be directed to deficiency of the prior art, and provides a kind of convex closure shaping diel,
The convex closure good product quality come out using the mould molding, it is possible to increase operating efficiency.
The purpose of this utility model is achieved through the following technical solutions：A kind of convex closure is molded diel, including from up to
Under the upper die and lower die that set gradually, the upper mould be provided with the cavity and the lower mould for being used for being molded convex closure be provided be used to being molded it is convex
The boss of bag, the cavity of upper mould offers air-vent at least one, and the boss of lower mould offers at least one lower air-vent.
Wherein, the upper air-vent is provided with multiple, and multiple upper air-vents are distributed on the cavity of mould.
Wherein, the upper mould offers multiple upper grooves, and multiple upper grooves are distributed on the top surface of the upper mould, described upper
Stomata is opened in the bottom land of the upper groove.
Wherein, the upper groove is provided with nine, and nine upper grooves are arranged in arrays, and the bottom land of each upper groove offers 3 ~
5 upper air-vents.
Wherein, the aperture of the upper air-vent is 3 millimeters to 8 millimeters.
Wherein, the lower air-vent is provided with multiple, and multiple lower air-vents are distributed on the boss of lower mould.
Wherein, the lower mould offers multiple low grooves, and multiple low grooves are distributed on the bottom surface of the lower mould, described lower
Stomata is opened in the bottom land of the low groove.
Wherein, the low groove is provided with nine, and nine low grooves are arranged in arrays, and the bottom land of each low groove offers 3 ~
5 lower air-vents.
Wherein, the aperture of the lower air-vent is 3 millimeters to 8 millimeters.
The beneficial effects of the utility model：In the convex closure shaping diel course of work of the application, when upper mould falls simultaneously
When being molded convex closure with lower die combination, the gas between upper mould and product can be discharged from upper air-vent, lower gas between mould and product
Know from experience from the discharge of lower air-vent, and then be not in excessive gas in die cavity when being brought into close contact mould, product and lower mould, and then
The convex closure of shaping will not produce bubble and produce stress, reduce the generation of bad products, solve conventional forming quality of products not
The problem of good.
