After the lower surface of the upper mold core and the upper surface of the lower mold core are bonded together, a plurality of mutually independent sealing plug plastic sealing cavities are formed between the two. Two upper mold cores are arranged in the upper accommodating groove, and two lower mold cores are arranged in the lower accommodating groove. One upper mold core corresponds to one lower mold core. The upper end of the plastic sealing tube passes through the mold base and the lower guide plate and stops at the upper surface of the lower guide plate. A distribution flow groove is opened on the lower surface of the lower loading plate. The distribution flow channel passes through the lower mold core and the lower loading plate to form a one-to-one corresponding connection with the sealing plug plastic sealing cavity. Although the above patent structure is reasonably designed, during the separation process, the upper movable template loses pressure on the first movable plate due to the rise, and a gap is generated between the upper movable template and the first movable plate, so that the spring between the second movable plate and the lower movable template is stretched, and the extension of the spring can make the first movable plate and the second movable plate rise, thereby driving the ejector rod to retract upward, so that the molded sealing plug in the sealing cavity of the sealing plug is automatically removed, and the sealing work of multiple sealing plugs can be completed at one time and automatic removal can be achieved to improve the sealing efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the upper module on the upper mold and the lower module on the lower mold are used to perform the plastic sealing operation of the product. During the plastic sealing process, the first plastic sealing ring and the second plastic sealing ring on the upper mold are arranged to facilitate the injection of plastic sealing raw materials. The first plastic sealing ring is embedded in the interior of the second plastic sealing ring. The inner side wall of the first plastic sealing ring and the top of the second plastic sealing ring form a plastic sealing groove. The formed plastic sealing groove is arranged in a hollow inverted truncated cone shape. The formation of the inverted truncated cone-shaped plastic sealing groove can facilitate the injection of plastic sealing raw materials and reduce the problem of splashing of raw materials to the top of the upper mold when injecting. The lower module is arranged to be composed of the first solid The upper module is composed of a fixed ring, a second fixed ring and a third fixed ring, and a first limiting groove is formed between the first fixed ring and the second fixed ring, and a third limiting groove is formed between the second fixed ring and the third fixed ring. A fourth fixed plate and a first molded part are arranged on the upper module, and the first molded part is embedded in the interior of the fourth fixed plate, and the height of the first molded part is higher than the fourth fixed plate. Therefore, when the first molded part is sleeved in the interior of the lower module, the fourth fixed plate is clamped with the second limiting groove, thereby enhancing the stability between the first molded part and the lower module, thereby facilitating the plastic sealing operation of the first molded part and the second molded part.

[0019] 2. The plastic sealing operation is realized by utilizing the gap formed between the first molded part and the second molded part, the first lampshade mold and the second lampshade mold are arranged inside the second molded part, the upper module is arranged in a mode in which the first molded part and the second molded part are nested, and the first plastic sealing tube is arranged inside the second lampshade mold. The first plastic sealing tube is arranged in an annular shape, and the first plastic sealing tube surrounds the inner side wall of the second lampshade mold. The annular arrangement of the first plastic sealing tube can promote the uniformity of the plastic sealing raw material during the flow process, and multiple second plastic sealing tubes are arranged to be connected with the first plastic sealing tube, and the multiple second plastic sealing tubes are equidistantly distributed around the inner side wall of the second lampshade mold, so as to further promote the uniformity of the distribution of the plastic sealing raw material. At the same time, it can effectively prevent the phenomenon of inadequate plastic sealing at the bottom ends of the first lampshade mold and the second lampshade mold. The plastic sealing material located between the first lampshade mold and the second lampshade mold can reach the bottom ends of the first lampshade mold and the second lampshade mold during the rotation of the second lampshade mold, thereby solving the problem of incomplete plastic sealing due to uneven pressure inside the plastic sealing mold in the prior art. The second lampshade mold is located inside the first lampshade mold and is rotatably connected to the first lampshade mold. Therefore, when the second lampshade mold rotates inside the first lampshade mold, the second lampshade mold rolls the plastic sealing material at the bottom ends of the first lampshade mold and the second lampshade mold. Therefore, when the second lampshade mold rotates inside the first lampshade mold, it can effectively prevent the plastic sealing material from flowing to the bottom ends of the first lampshade mold and the second lampshade mold to accumulate and generate bubbles, thereby improving the plastic sealing efficiency of the plastic sealing mold and the exquisiteness of the plastic sealing, and reducing the generation of burrs during the plastic sealing process.

[0020] 3. By setting the first plastic sealing part, the second plastic sealing part and the third plastic sealing part, the plastic sealing material is sealed between the first molded part and the second molded part through the first plastic sealing part, the second circulation tube, and the third circulation tube arranged inside the second plastic sealing part, which can facilitate the circulation of the plastic sealing material. The driving force of the plastic sealing material itself and the guidance of the first circulation tube, the second circulation tube and the third circulation tube are utilized to control the rapid flow of the plastic sealing material, thereby further promoting the plastic sealing efficiency of the plastic sealing mold.
