Background technique
Rubber seal is that a kind of general basic element in sealing device is stretched since it is very small with elasticity modulus
The advantages of long rate is high, air permeation resistance and be widely used in being mounted in various equipment.But in traditional adapter of plastic, due to
The narrow space of cooperation, install make connector be difficult to install after rubber seal, snapping, lead to poor sealing.
Summary of the invention
To solve to make connector be difficult to snapping after installing rubber seal in adapter of plastic, lead to asking for poor sealing
Topic seals featheredge rubber parts the present invention provides a kind of band and makes the molding die of the rubber parts.
The technical solution adopted by the present invention is as follows：
A kind of band sealing featheredge rubber parts, including lateral wall and inner sidewall, the inner sidewall are equipped with No.1 groove, the outside
Wall is equipped with No. two grooves, the featheredge of No. two bottom portion of groove being circumferentially with diagonally downward and outwardly, the thickness of the featheredge
It is gradually thinning from top to bottom.
A kind of molding die of band sealing featheredge rubber parts, including upper mold, middle mould, cover half and lower die, it is mutually matched
Forming cavity is constituted between upper mold, middle mould, cover half and lower die, the periphery of the forming cavity is equipped with flash gutters.
The forming cavity includes end face chamber, side wall chamber, featheredge chamber, and end face chamber is constituted between the upper mold and cover half, described
Cover half and middle mould constitute side wall chamber, and the middle mould and lower die constitute featheredge chamber.
The cover half is equipped with trapezoidal shape protrusion, and the bottom edge length of the trapezoidal shape protrusion is less than top margin length, the lower die
Equipped with the groove with trapezoidal shape male cooperation.
The flash gutters are contacted with forming cavity for line, and the flash gutters become larger far from the width of forming cavity.
The section of the flash gutters is in triangular shape.
The upper mold, middle mould and lower die are positioned and are connected by guide post.
The upper mold is equipped with several gas vents.
The upper mold, middle mould and lower die are equipped with handrail.
The beneficial effects of the invention are as follows：
The thickness of the featheredge of rubber parts of the present invention is gradually thinning from top to bottom and towards outer incline, becomes adapter of plastic buckle, installation
Must be simple and convenient, and can make mutually matched connector that there is good leakproofness.

Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing：
In embodiment, as shown in Figure 1 and Figure 2, a kind of band sealing featheredge rubber parts, including lateral wall 1 and inner sidewall 2, it is described interior
Side wall 2 is equipped with No.1 groove 3, and the lateral wall 1 is equipped with No. two grooves 4, and being circumferentially with for 4 bottom of No. two grooves is tilted towards
Lower and featheredge 5 outwardly, the thickness of the featheredge 5 are gradually thinning from top to bottom.The thickness of the featheredge 5 of rubber parts from top to bottom by
Gradual change is thin and towards outer incline, so that adapter of plastic buckle, installation is become simple and convenient, and it is good that mutually matched connector can be made to have
Leakproofness.
In embodiment, as shown in figure 3, a kind of molding die of band sealing featheredge rubber parts, including it is upper mold 6, middle mould 7, fixed
Mould 8 and lower die 9 constitute forming cavity 10, the forming cavity between mutually matched upper mold 6, middle mould 7, cover half 8 and lower die 9
10 periphery is equipped with flash gutters 11；The forming cavity 10 includes end face chamber 101, side wall chamber 102, featheredge chamber 103, the upper mold 6
End face chamber 101 is constituted between cover half 8, the cover half 8 constitutes side wall chamber 102 with middle mould 7, and the middle mould 7 constitutes thin with lower die 9
Side chamber 103.Each mold is easy to process, convenient after rubber parts molding to take out in mold.
In embodiment, as shown in figure 3, the cover half 8 is equipped with trapezoidal shape protrusion 12, the bottom side length of the trapezoidal shape protrusion 12
Degree is less than top margin length, and the lower die is equipped with the groove 13 with 12 cooperation of trapezoidal shape protrusion.Cover half is mating, ladder with lower die
Shape protrusion 12 cooperates with groove 13, and when mating is completed, there are gaps with 13 bottom of groove for trapezoidal shape protrusion 12, guarantees cover half
With the accuracy of lower die cooperation.
In embodiment, as shown in figure 3, the flash gutters 11 are contacted with forming cavity 10 for line, the flash gutters 11 far from
