Specific embodiment
More clearly to indicate, the present invention is described in detail with reference to the accompanying drawing.
The present invention provides a kind of O-ring molding die, incorporated by reference to referring to figs. 2 and 3.O-ring molding die includes upper mold
110, the upper mold 110 has the upper back side (not marking) and upper mold die face (not marking, i.e. die face shown in Fig. 2), the upper mold mould
Face has upper impression 116, and in the present embodiment, mold has 16 type chambers, shown in Fig. 2.O-ring molding die includes lower die 120,
The lower die 120 has the lower back side and lower die die face, and there are the lower die die face lower impressions (to be not shown, can refer to upper impression
116).O-ring molding die further includes positioned at the gluing road 112 of the upper mold die face, the gluing road 112 and the upper impression
116 connections.O-ring molding die further includes positioned at the road Xia Jiao (being not shown, can refer to the road Xia Jiao) of the lower die die face, institute
The road Shu Xiajiao is connected to the lower impressions.
As shown in Figures 2 and 3, the upper mold 110 also has the injection hole 111 through the upper back side and upper mold die face, described
Injection hole 111 is connected to the gluing road 112, and when the upper mold 110 and lower die 120 are combined, the injection hole
111 are located above the road Xia Jiao.
Referring to FIG. 4, show the enlarged diagram of one of upper impression 116, the upper impression 116 of the upper mold die face
Periphery tool is upper torn edges slot 1161, and the upper torn edges slot 1161 is connected to the upper impression 116, the gluing road 112 with it is described
Upper torn edges slot 1161 is connected to (in conjunction with reference Fig. 3).
The lower impressions periphery tool of the lower die die face is lower torn edges slot (being not shown, incorporated by reference to reference to upper torn edges slot), described
Lower torn edges slot is connected to the lower impressions, and the road Xia Jiao is connected to the lower torn edges slot.
It should be noted that in order to guarantee that the material of O-ring can be from the upper torn edges slot 1161 for being located at 116 outside of upper impression
Into upper impression 116, the size of the upper torn edges slot 1161 of the present embodiment increase, the size of upper and lower torn edges slot respectively increases by five silks (one
Silk is 0.01 millimeter), correspondingly, the final products torn edges edge of a knife can be made respectively to increase by 5 silks up and down.
The injection hole 111 is located at the center of the upper mold die face.In other embodiments, injection hole may not necessarily be located at upper
The center of mould die face, and it is possible to be multiple.
The side of the upper mold 110 and the lower die 120 is connected using hinge structure 115.
Two edges that the lower die die face and the hinge structure 115 are away from each other side have sled mouth 114.Prize mouth
114 can facilitate die sinking.
With continued reference to FIG. 3, in the present embodiment, the die face of upper mold 110 also has that there are four guide posts 113, and in lower die 120
There is corresponding guide sleeve (being not shown, can also claim guide hole), by guide post 113 and guide sleeve, so that upper mold 110 and lower die 120 are molding
Later, position will not find to move, meanwhile, also facilitate the contraposition fast and accurately of clamping process.
In the present embodiment, as shown in figure 3, being connected to the same of gluing road 112 in four upper impressions 116 of two rows two column arrangement
One point.The same point in the road Xia Jiao is connected in four lower impressions of two rows two column arrangement.
Referring to FIG. 5, showing using the O-ring 200 of the present embodiment provided O-ring molding die production and O-shaped
The part enlarged structure of circle 200.At this time it can be found that O-ring 200 there may not necessarily be interior torn edges, and only has outer torn edges 210
(by being molded in upper torn edges slot 1161 and lower torn edges slot), i.e., do not have torn edges in the circle of O-ring 200.And use existing mould
When having compression moulding, can exactly occur the torn edges outside the torn edges and circle that are located in O-ring circle simultaneously.
It follows that sizing material can be from the torn edges edge of a knife (torn edges slot and type in O-ring molding die provided in this embodiment
The intersection of chamber) injection type chamber, and O-ring production can be carried out by injection moulding (ejection formation), sizing material is from torn edges knife
Mouth injection saves artificial material reducing, weighing, pendulum material, reduces work hours, reduce cost of labor.Also, mold body is not easy to wear, mould
Tool is not easy to damage by pressure, damage, and increases die life.Meanwhile product produced will not lack material, improve product yield.In addition, also
The accurate exactness of product can be increased by strict control material weight.
Referring to FIG. 6, providing another O-ring molding die, the big portion of the O-ring molding die and previous embodiment
Separation structure is identical, such as upper mold 310 has injection hole 311, gluing road 312 and guide post 313.The difference is that shown in Fig. 6
Upper mold 310 in, show that the present embodiment is the mold with 64 cavity structures.
Also, corresponding gluing 312 design method of road is different.Two column upper impressions 314 connect one between them simultaneously
Glue road 312.Correspondingly, in unshowned lower die, likewise, two column lower impressions connect between their (two column lower impressions) simultaneously
A road Xia Jiao.
In other embodiments, the upper impression while connection two being also possible between the two column gluing road are arranged on described
Jiao Dao.Correspondingly, in unshowned lower die, likewise, the lower impressions between the road Xia Jiao described in two rows connect two rows simultaneously
The road Xia Jiao.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
