Description

BGA plastic package mould

Technical Field

The utility model belongs to the technical field of plastic packaging equipment, and particularly relates to a BGA plastic packaging mold.

Background

In the existing BGA packaging mold, an inflatable sealing ring is mostly adopted, but the inflatable sealing ring is easy to age and damage, poor sealing is easy to occur during plastic packaging and mold closing after damage, or air leakage causes deviation of material strips, and the production line has low yield.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a BGA plastic package mold, which avoids the defects of an inflatable sealing ring.

In order to solve the above problems, the present invention provides a BGA plastic package mold, including: the sealing piece comprises a solid sealing layer and an auxiliary sealing layer covering the solid sealing layer, and the auxiliary sealing layer is softer than the solid sealing layer.

Optionally, the edge of the upper cover is provided with a groove surrounding the circumference, and the solid sealing layer is arranged in the groove.

Optionally, the auxiliary sealing layer covers an opening of the groove.

Optionally, the solid sealing layer partially protrudes the groove.

Optionally, the solid sealing layer is a rubber ring.

Optionally, the auxiliary sealing layer is attached by using an adhesive.

Optionally, the sealing device further comprises a lower cover, and after the lower cover and the upper cover are closed, a working area is defined between the sealing elements.

According to the inflatable sealing ring, the arranged sealing element comprises the solid sealing layer and the auxiliary sealing layer covering the solid sealing layer, the auxiliary sealing layer is softer than the solid sealing layer, the problem that the inflatable sealing ring is easy to damage is solved, the sealing effect is improved through the two sealing layers with different softness, and the sealing effect of the solid sealing element is not lower than that of the inflatable sealing element.

Detailed Description

The technical scheme of the utility model is clearly and completely described in the following with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

The utility model will be further explained with reference to the drawings.

Referring to fig. 1 and fig. 2, the present invention provides a BGA plastic package mold, including: the sealing structure comprises an upper cover 10, wherein a sealing element is arranged on the periphery of the upper cover 10, the sealing element comprises a solid sealing layer 20 and an auxiliary sealing layer 30 covering the solid sealing layer 20, and the auxiliary sealing layer 30 is softer than the solid sealing layer 20.

In an embodiment of the present invention, the solid sealing layer 20 may be made of a rubber material, and specifically, for example, is a rubber ring. Further, steel wires may be provided inside to enhance the toughness thereof.

The auxiliary sealing layer 30 may be made of a foam material, for example, and has good elasticity; a material such as rubber that is softer than the solid sealing layer 20 may be used.

In the present invention, the specific materials of the solid sealing layer 20 and the auxiliary sealing layer 30 are not particularly limited, and only the solid sealing layer is relatively hard, but the auxiliary sealing layer 30 is soft, such a double-layer design can achieve a better sealing effect.

Referring to fig. 2, in the present invention, a groove 101 is formed around the periphery of the upper cover 10, and the solid sealant 20 is disposed in the groove 101.

As can be seen in fig. 2, the solid sealant layer 20 partially protrudes from the recess 101. Specifically, the solid sealant 20 may have a circular cross section and match the groove 101, wherein it is preferable that the center of the solid sealant 20 is located in the groove 101, so that the structure is more stable.

Accordingly, the auxiliary sealing layer 30 covers the opening of the groove 101, conforms to the shape of the solid sealing layer 20, and has a protrusion.

Further, the auxiliary sealing layer 30 is attached by using an adhesive. Thus, if the auxiliary seal layer 30 is damaged, it is easy to replace the auxiliary seal layer.

Optionally, a lower cover (not shown) is included, and when the lower cover is closed with the upper cover 10, a working area 40 is defined between the sealing members.

When the upper cover and the lower cover are closed, the solid sealing layer 20 plays a main body support of the sealing element, and the auxiliary sealing layer 30 increases the contact area, so that the sealing effect is ensured.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.

Other parts of the utility model not described in detail are prior art and are not described in detail herein.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
