Abstract
The utility model relates to a secondary rubber coating mould device field indicates a secondary rubber coating product especially. The encapsulation structure comprises an encapsulation body and salient points, wherein two rows of metal pin groups are arranged on the encapsulation body; a secondary rubber coating die is sleeved outside the rubber coating body; salient points are arranged on two contact surfaces of the rubber coating body, which are in contact with the secondary rubber coating die; so that the primary encapsulated product in the secondary encapsulated product does not obstruct the flow of the secondary encapsulated plastic.
Description
Technical Field
The utility model relates to a secondary rubber coating mould device field indicates a secondary rubber coating product especially.
Background
At present, encapsulation is needed in the production process of a die, and primary encapsulation and secondary encapsulation are generally adopted; because the secondary encapsulated product has waterproof requirements, the primary encapsulated product can not be exposed to the outer side of the secondary encapsulated product and only has a limiting needle point which can be exposed, and the limiting needle point can not be obviously detected by naked eyes, and the primary encapsulated product does not need to block the flow of the secondary encapsulated plastic in the production process; however, the existing mould can not meet the requirements, so that a primary encapsulated product is exposed in a large area, and the waterproof grade of the product is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a secondary rubber coating product that once rubber coating product does not obstruct the flow of secondary rubber coating plastics.
The technical scheme of the utility model as follows:
a secondary rubber-coated product comprises a rubber-coated body and salient points, wherein two rows of metal pin groups are arranged on the rubber-coated body; a secondary rubber coating die is sleeved outside the rubber coating body; salient points are arranged on two contact surfaces of the rubber coating body and the secondary rubber coating die.
The salient points are conical salient points.
The metal pin groups comprise at least two metal pins.
The metal contact pins on the front side in the metal contact pin group are two metal contact pins, and the metal contact pins on the rear side are three metal contact pins.
The utility model has the advantages that: the utility model ensures that the primary rubber-coated insert is suspended in the middle of the secondary rubber-coated part on the primary rubber-coated product, so that the primary rubber-coated product is exposed outside the secondary rubber-coated product in a minimized way; the encapsulation body is supported by the conical salient points, so that the encapsulation body can be suspended in the secondary encapsulation die; because the metal contact pin group is positioned on the top surface of the rubber coating body, the primary rubber coating product in the secondary rubber coating product does not block the flow of the secondary rubber coating plastic.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the bottom structure of the present invention;
FIG. 3 is a schematic structural view of the secondary rubber-coated product of the present invention;
in the attached drawing, 1 is the rubber coating body, 2 is the plug pin seat, 3 is the toper bump, 4 is the metal contact pin, 6 is the cylinder section, and 7 is the cone section.
Detailed Description
Referring to fig. 1-3, a secondary rubber-coated product comprises a rubber-coated body 1 and conical bumps 3, wherein two rows of metal pin groups are arranged on a pin base 2 on the top surface of the rubber-coated body; conical salient points 3 are arranged on two contact surfaces of the rubber coating body, which are in contact with a secondary rubber coating die, and the rubber coating body is supported through the conical salient points (the contact surfaces of the rubber coating body are mainly the top surface and the bottom surface of the rubber coating body), so that the rubber coating body can be suspended in the secondary rubber coating die; because the metal contact pin group is positioned on the top surface of the rubber coating body, the primary rubber coating product in a secondary rubber coating product does not block the flow of secondary rubber coating plastic; the salient points are conical salient points, the head parts are needle-point-shaped, and the exposure of primary encapsulation is minimized after secondary encapsulation; the conical salient points can be uniformly distributed according to the characteristics of the product, each part can be supported up and down, and the phenomenon that the primary rubber coating piece is driven by injection molding pressure during secondary rubber coating and injection molding is avoided.
The conical salient point comprises a cylindrical section 6 and a conical section 7 on the top surface of the cylindrical section. In general, the conical salient points can be directly conical sections; however, under the condition that the cone is higher and the position is limited, the cylindrical section structure can be added to ensure that the primary encapsulated product does not block the flow of the secondary encapsulated plastic.
The metal pin groups each include at least two metal pins 4. And at least two metal pins are convenient to assemble.
The metal contact pins on the front side are two metal contact pins, and the metal contact pins on the rear side are three metal contact pins. Because the distribution of the metal contact pins is front two and back three, the assembly of the metal contact pins and other parts is more convenient.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
