[0040] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0041] In the field of injection molding products, injection molds generally use multi-cavity injection molds, that is, multiple cavities are set on the injection mold, such as 8-cavity, 16-cavity, 32-cavity, etc., so that multiple injection products can be molded at one time by setting multiple cavities. At present, the injection products of different cavities in the injection mold are generally taken out and put into the receiving box through the distribution pipe. However, due to static electricity or the product is too light, the product is easily adsorbed on the distribution pipe, resulting in the product cannot be smoothly put into the receiving box and difficult to take out, which seriously affects the efficiency of automated production and affects the product delivery time.

[0042] In order to solve the above problems, Figure 1 , Figure 2 As shown, this embodiment provides a hole-dividing device for injection molding products. The hole-dividing device includes a docking plate 1, a sealing box mechanism 2, and a plurality of material-dividing pipes 4. The docking plate 1 is provided with a plurality of material-dividing ports 11, the sealing box mechanism 2 includes a receiving cavity, a plurality of material-receiving boxes 3 are placed in the receiving cavity, a plurality of air holes are provided on the material-receiving boxes 3, the sealing box mechanism 2 is externally connected to an air suction device, the air suction device can suck air to generate negative pressure in the receiving cavity, one end of each material-dividing pipe 4 is connected to each material-dividing port 11 in a one-to-one correspondence, and the other end of each material-dividing pipe 4 is penetrated and fixed to the sealing box mechanism 2 and is respectively opposite to each material-receiving box 3.

[0043] First, the injection molded products produced by each cavity of the injection mold are taken out by a manipulator with a take-out device, and then the take-out device is docked with the docking plate 1, so that each discharge port of the take-out device corresponds to each feed port 11, and then the suction device is started to generate negative pressure in the accommodating chamber. It can be understood that since a number of air holes are provided on the receiving box 3, negative pressure is also generated in the receiving box 3. The take-out device releases the injection molded products, and the injection molded products produced by each cavity of the injection mold enter different receiving boxes 3 through each feed port 11 and feed pipe 4, respectively, to achieve classification and induction. In this way, the injection molded products stored in each receiving box 3 are produced by the same cavity, and the operator can understand the conditions of each cavity of the injection mold through the quality of the injection molded products stored in different receiving boxes 3. When a defect occurs in an injection molded product in a certain receiving box 3, it can be understood in time, which is convenient for the maintenance of the injection mold, and the defective products produced by the problematic cavity can be directly scrapped, thereby avoiding confusion between defective products and qualified products, facilitating product testing, and effectively improving production efficiency. The suction device generates negative pressure in the accommodating cavity, so that the injection molded product can enter the corresponding receiving box 3 more smoothly along the material distribution pipe 4, and there will be no situation where the injection molded product is adsorbed on the material distribution pipe 4 due to static electricity or the light weight of the injection molded product, resulting in the product being unable to be smoothly put into the receiving box 3 and difficult to take out. This hole distribution device has a simple structure, is safe to use, and is easy to operate. It can realize the effective collection of injection molded products, ensure the stable collection of injection molded products, and improve production efficiency.

[0046] Preferably, the feed pipe 4 is a transparent structure, so that the operator can observe the injection molded product passing through the feed pipe 4. If the injection molded product gets stuck in the feed pipe 4, the machine can be shut down for maintenance in time to avoid unnecessary losses.

[0047] In this embodiment, if Figure 1 As shown, the distribution pipe 4 includes a first pipe portion 41, a second pipe portion 42 and a third pipe portion 43 which are sequentially connected from top to bottom, wherein the first pipe portion 41 and the third pipe portion 43 are arranged vertically, and the second pipe portion 42 is arranged obliquely, so that the distribution pipe 4 is arranged obliquely as a whole, which can play a buffering role on the injection molded products passing through the distribution pipe 4, reduce the falling speed of the injection molded products, and avoid damage to the injection molded products.

[0048] For more details, see Figure 1 The material distribution port 11 is equipped with a first connecting tube 7, which is connected to the material distribution port 11 by means of clamping, welding or bonding.

[0053] Specifically, the bottom plate is provided with a plurality of placement grooves, and the plurality of material receiving boxes 3 are respectively embedded in the plurality of placement grooves. The placement grooves enable the material receiving boxes 3 to be stably placed on the bottom plate, and prevent the material receiving boxes 3 from sliding, shifting or tipping on the bottom plate, resulting in the spillage of the injection molded product.

[0054] Preferably, if Figure 1 As shown, the cavity device of the injection molding product includes a base 5, and the sealing box mechanism 2 is arranged on the base 5. The base 5 provides stable support for the entire cavity device, and can be connected to other equipment through the base 5.
