[0015] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0016] like Figure 1-4 As shown, the utility model provides a PCR glue core pre-mouth plate, including a main board 1, a conical glue channel 2 is opened in the main board 1, and the bottom of the conical glue channel 2 is a glue outlet 6, and the glue outlet 6 is divided into a apex glue outlet 7 and a apex glue outlet 8. The area of ​​the apex glue outlet 7 is larger than that of the apex glue outlet 8. In the conical glue channel 2, a filling plate 5 is arranged on the side away from the apex glue outlet 7, and the cross section of the filling plate 5 is trapezoidal, which divides the conical glue channel 2 into an upper glue channel 3 and a lower glue channel 4. By setting a conical glue channel, the extrusion process of the apex can be smoother, and the demand for extrusion pressure is reduced.

[0017] Without changing the shape of the glue outlet 6, by setting the filling plate 5, the amount of glue flowing from the glue outlet 7 at the edge of the apex during the extrusion process of the apex can be made greater than the amount of glue flowing from the glue outlet 8 at the root of the apex, thereby increasing the expansion of the glue at the edge of the apex and reducing the expansion of the root of the apex. Finally, when the apex is attached, the shrinkage of the edge of the apex can be reduced, thereby slowing down the curling of the PCR glue core.

[0018] The four sides of the main board 1 are provided with an outward-turned frame 9, which can match the shape of the extrusion port, so as to facilitate installation and disassembly. Figure 5 As shown, in one embodiment, the length of the glue outlet 6 is 80 mm, and the thickness of the filling plate 5 at the end of the tapered glue channel 2 is 9 mm. The protruding length of the filling plate 5 at the lower glue channel 4 is 45 mm, and the longitudinal depth is 10 mm; the protruding length of the filling plate 5 at the upper glue channel 3 is 50 mm, and the longitudinal depth is 12.5 mm. After testing, this size design can better meet the actual production needs.

[0019] By setting a narrower space of the lower glue channel 4, the resistance of the root glue material entering the lower glue channel 4 can be increased, and the amount of glue flowing from the root glue outlet 8 of the apex glue can be further reduced.

[0020] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
