DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to specific embodiments.

[0018] Example:

[0019] like Figures 1 to 4As shown, a PCIE slot shell molding mold of the present invention comprises a male mold and a female mold, a pair of opposite surfaces of the male mold and the female mold are provided with grooves, and connecting block assemblies are provided at both ends of the groove, and the connecting block assembly comprises a first connecting block 1 connected to the male mold and a second connecting block 2 connected to the female mold, the two connecting block assemblies and the groove constitute a closed cavity, and the two first connecting blocks 1 are respectively provided with a glue inlet 3 and a glue outlet 4, an upper and lower needle plates 5 are provided in the male mold, and a plurality of PIN needles 6 are provided on one end of the two needle plates 5 close to the female mold, a tongue plate 7 is provided in the female mold, and a fixing plate 8 is provided on the upper and lower sides of the tongue plate 7, and the front end of the tongue plate 7 extends between the two needle plates 5, and a plurality of PIN needle limiting grooves 9 are provided on the upper and lower sides of the tongue plate 7, and a plurality of needle end limiting grooves 10 are provided on the side of the two fixing plates 8 facing the PIN needle 6. After the mold is assembled, the PIN needle 6 is inserted into the PIN needle limiting groove 9, and the end of the PIN needle 6 is inserted into the needle end limiting groove 10. The needle end limiting groove 10 is a through groove connecting the cavity and the outside world to prevent the formation of a closed space after the PIN needle 6 is inserted. The glue is fed into the mold through the glue inlet 3, and the air and excess glue are discharged from the glue outlet 4. Because the PIN needle 6 and the needle end limiting groove 10 limit and support the PIN needle 6, the PIN needle 6 can be prevented from being bent during the glue feeding process, thereby ensuring the injection molding quality.

[0020] The male mold includes an upper module 11 and a lower module 12 and two layers of needle plates 5 arranged therebetween. The first connecting block 1 is set to be C-shaped. The ends of the upper module 11 and the lower module 12 are clamped on the inner side of the first connecting block 1. A pin connecting block 13 is also provided between the upper module 11 and the lower module 12. The pin connecting block 13 is provided with an ejector hole. The rear end faces of the upper module 11, the lower module 12 and the ejector connecting block 13 are all provided with a limiting plate 14 extending outward and resting on the rear end face of the first connecting block 1. The female mold is similar in design to the male mold.

[0021] The needle plate 5 is segmented and is formed by splicing a plurality of small needle plates. A plurality of limiting grooves are vertically provided on the rear end surfaces of the upper module 11 and the lower module 12, and a limiting block 15 is integrally formed on the small needle plate.

[0022] A limiting protrusion 16 and a limiting recess 17 are respectively provided on a pair of opposite surfaces of the first connecting block 1 and the second connecting block 2 .

[0023] The beneficial effects of the present invention are as follows: the PIN needle 6 and the needle end limiting groove 10 limit and support the PIN needle 6, which can prevent the PIN needle 6 from being bent during the glue injection process, thereby ensuring the injection molding quality. The male mold and the female mold both adopt a modular design. The upper module 11, the lower module 12, the first connecting block 1 and the needle plate 5 are mutually limited and assembled into the mold core. The needle plate 5 adopts a segmented design. When a PIN needle 6 is bent, it is only necessary to replace the small needle plate with the PIN needle 6, thereby quickly completing the maintenance of the mold.

[0024] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
