AI Technical Summary
In existing injection molding equipment, liquid plastic tends to seep out and adhere to the mold surface after the extruder head leaves the mold, making cleaning inconvenient and difficult to prevent leakage of liquid plastic from the extruder head.
An injection molding device with an anti-permeability sealing component was designed, comprising a scraper and a collection plate structure. The scraper and the collection plate are positioned at the top of the injection tube. After injection, the scraper drops down to scrape off the residual liquid plastic, which is then collected into a collection tank through a guide channel to prevent leakage or falling.
It effectively prevents the leakage and contamination of liquid plastic, achieving a cleaner and more efficient dispensing process.

Description
Technical Field
[0001] The utility model relates to glue injection equipment, in particular to an injection molding device with an anti-penetration sealing component. Background Art
[0002] The glue injection equipment is used to inject the molten plastic into the mold. Through the gap set inside the mold, the molten liquid plastic cools and solidifies in the gap inside the mold, thereby producing a product that does not require splicing and assembly. This method can reduce subsequent processing steps.
[0003] Publication number CN116572485B is a Chinese invention patent, which discloses an injection molding device with an anti-penetration sealing component, and relates to the technical field of injection molding equipment. The present invention includes an extrusion bin, one end of which is connected to an extrusion tube, the output end of which is connected to an extrusion head, and a baffle plate is installed on the outside of the extrusion tube. The baffle plates are provided in four groups, and the specifications and sizes of the four groups of baffle plates are consistent, and the surface of the lower baffle plates in the four groups of baffle plates is provided with a plurality of filter holes, and the baffle plates are connected to extension plates on both sides, and the inner side of the baffle plates is connected to a buffer connecting rod, and one end of the buffer connecting rod is connected to a sealing pad, and the sealing pad is adapted to the position of the extrusion head; in the process of extruding the material, the baffle plate is used to enclose and protect the extrusion tube and the extrusion head, and the baffle plate is turned over and opened by the first horizontal push rod in cooperation with the roller shaft, and the inner buffer connecting rod cooperates with the sealing pad at one end to seal the outer edge side of the material output port of the extrusion tube and the extrusion head, and the two groups of mechanisms cooperate to prevent the extruded material from leaking out.
[0004] In combination with the above-mentioned technologies, the injection molding material is extruded through the extrusion bin through the extrusion tube and the extrusion head. During the extrusion of the material, the extrusion tube and the extrusion head are enclosed and protected by the baffle plate to prevent the extruded material from seeping out. After the baffle plate blocks the liquid plastic from seeping out, the liquid plastic is easy to solidify on the surface of the baffle plate, which makes cleaning inconvenient. After the extrusion head leaves the mold, the liquid plastic seeping out of the extrusion head is easy to continue to seep out. When the extrusion head is processed, it is easy to pull out the liquid plastic from the extrusion head and let the liquid plastic adhere to the surface of the mold. Therefore, it is necessary to develop a new type of injection molding equipment. Utility Model Content

The shape of the extrusion block 413 facing the glue injection hole is consistent with the end of the glue injection tube 4 provided with the glue injection hole. A moving rod 412 is connected to the side of the extrusion block 413 away from the glue injection hole. A closed ring 414 is sleeved on the top of the moving rod 412. A toggle block 411 is connected to the other end of the moving rod 412. The other end of the toggle block 411 is connected to one end of the driving rod 41.
