Embodiment
The embodiment of the present invention is described further with reference to Fig. 1 to Fig. 9.
Embodiment one：
The connection method of the silica gel and element of a kind of ejection formation, comprises the following steps：S-1, in mould in advance
Arrange the element to be connected；S-2, liquid silica gel, the liquid silicon are injected in mould by the way of vertical injection
Glue submerges the lower end of the element；S-3, shaping silica gel is stripped after liquid silica gel cooling.In the present invention, the liquid
Silica gel is molded by the way of ejection formation.
For the element used in the present embodiment for plastic parts, the lower end of the plastic parts is disposed with multiple holes and/or multiple
Projection 1, each described hole be blind hole 3 and/or through hole 2, the lower end of the plastic parts be molded silica gel by each described hole and/
Or projection 1 is mutually embedded.Each described hole and/or the arbitrarily arrangement of projection 1, can be with transverse and longitudinal ordered arrangement, also can mutually straggly point
Cloth, the present embodiment protrusions 1, blind hole 3 and through hole 2 are arranged with, and are designed as transverse and longitudinal ordered arrangement, but per a line Hole and
Raised number is any.
Further, it is the contact area for increasing the element and being molded between silica gel, part design in each described raised 1
For tiltedly projection, remainder is straight raised, and the incline direction of each tiltedly projection is different；Each part of the blind hole 3
Oblique blind hole is designed as, remainder is straight blind hole, and the incline direction of each tiltedly blind hole is different；Each through hole 2 one
Part is designed as oblique through hole, and remainder is clear opening, and the incline direction of each tiltedly through hole is different.Can also be described
The surface layout of element has several grooves, in addition, each incline direction tiltedly between raised, oblique through hole and oblique blind hole is also mutual
Differ.Therefore when element is connected with shaping silica gel, contact area, and each tiltedly raised, oblique through hole are not only increased
Force direction between oblique blind hole and shaping silica gel is different, can have the effect for blocking shaping silica gel.In the present invention,
The lower end arrangement of the plastic parts is blind hole 3, through hole 2 and projection 1, but not in surface layout groove.
Each well described previously hole and projection 1 can arrange on each face that the element is connected with shaping silica gel.
If Fig. 3 is into Fig. 8, each described hole and the embodiment two, three, four of raised 1 different designs are followed successively by.
In the step S-2, the liquid silica gel is injected in the mould by the way of vertical injection, it is described
Liquid silica gel submerges each hole and projection 1 of the plastic parts.After liquid silica gel cooling and shaping, the lower end of the plastic parts leads to
Cross each described hole and raised 1 to be embedded among shaping silica gel, therefore, shaping silica gel energy multi-angle will be multi-level comprehensive to mould
The lower end of glue part is firmly wrapped up, so as to reach the effect of enhancing connection reliability.The exposed portion of the plastic parts can be used for real
Other existing functions.
The present invention not only increases the reliability of silica gel connecting element, and reduces procedure of processing, has saved and has been processed into
This, is significantly optimized to whole processing technology.
Embodiment five：
The present embodiment and the difference of embodiment one be, the lower end of the element include at least one external part 5 and with it is each
The connection end that the external part 5 matches, each described hole and/projection 1 are respectively positioned on the connection end.Stretched out in the present embodiment
The quantity at end 5 is two, and the quantity of connection end is one, and connection end is rectangle frame 6, and the face where the rectangle frame 6 has
Certain radian.The end of each external part 5 is arranged on the rectangle frame 6.
In other embodiments, the quantity of the rectangle frame 6 can be multiple that the quantity of the external part 5 can also be
It is multiple.For example, the end of each external part 5 is arranged with a rectangle frame 6, or it is disposed with least on a part of rectangle frame 6
Two external parts, an external part 5 is then disposed with remaining rectangle frame 6.
Embodiments of the present invention are explained in detail above in association with accompanying drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the technical field those of ordinary skill possessed knowledge
Put that various changes can be made.
