DETAILED DESCRIPTION

[0020] The utility model will be further described in combination with the drawings and embodiments.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , wherein Figure 1 A preferred embodiment structure diagram of the injection molding type runner cutting device provided by the utility model; Figure 2It is the structure schematic view of the mold in the utility model; Figure 3 It is the structure schematic view of the product cavity in the utility model; Figure 4 It is the structure schematic view of the ejector rod and the processed product in the utility model. A water gap cutting device of injection molding comprises an outer shell 1, the outer side of the outer shell 1 is provided with a positioning ring 2, the inside of the positioning ring 2 is provided with a flow channel 5 for adding injection molding material, the outer side of the outer shell 1 is provided with a mold 3, the outer side of the mold 3 is provided with a cooling water pipe 4 for cooling the mold, the outer side of the mold 3 is provided with a hot runner junction box 8; a processed product 6 is arranged on the outer side of the mold 3, the inside of the mold 3 is provided with a product cavity 9 for shaping the product, and the outer side of the product cavity 9 is provided with a sprue cutter 7.

[0022] 220-volt current enters the flow channel 5 through the hot runner junction box 8, so that the flow channel generates heat, and the injection molding material injected into the flow channel 5 of the mold by the injection molding machine quickly enters the product cavity 9 without losing temperature.

[0023] In the specific implementation process, as shown in Figure 2 and Figure 3 , the cooling water pipe 4 is provided with a plurality of groups around the outer side of the mold 3, and the inside is provided with cooling liquid.

[0024] It should be noted that: after the processed product 6 is cooled by the cooling liquid in the cooling water pipe 4, the processed product 6 is quickly cooled, which is beneficial to the mold opening of the injection molding machine.

[0025] As shown in Figure 4 , the outer side of the processed product 6 is provided with a water gap 10.

[0026] It should be noted that: the water gap 10 is the waste material generated between the processed product 6 and the flow channel 5 after the processed product 6 is shaped.

[0027] As shown in Figure 4 , the outer side of the sprue cutter 7 is provided with an ejector rod 12, and the outer side of the ejector rod 12 is provided with a hydraulic rod 11.

[0028] It should be noted that: the hydraulic rod 11 drives the movement of the ejector rod 12, and the ejector rod 12 pushes the sprue cutter 7 to cut off the water gap 10.

[0029] As shown in Figure 2 and Figure 3 , the flow channel 5 is located above the product cavity 9; the sprue cutter 7 is attached to one side of the product cavity 9, and is used for separating the water gap 10 from the processed product 6.

[0030] It should be noted that: the injection molding material enters the inside of the product cavity 9 from the flow channel 5, so that the product is shaped, and the sprue cutter 7 cuts off the water gap 10 along the side edge of the processed product 6.

[0031] The working principle of the injection molding type water gap cutting device is as follows:

[0032] 220-volt current enters the flow channel port 5 through the hot channel junction box 8, so that the flow channel generates heat, and the injection molding material injected into the mold flow channel port 5 by the injection molding machine quickly enters the product cavity 9 without losing temperature. The plastic entering the product cavity 9 is shaped by the product cavity, so it becomes a product state with a water gap 10. At this time, the mold material head cutter 7 is pushed into the product cavity 9 by the hydraulic rod 11 inside the mold, cutting off the water gap 10 part of the product with the water gap 10 and the product part. At this time, the injection material has not cooled in the cavity, so cutting is much easier than when the product cools. After the product is cut, the product is cooled by the cooling system in the mold, the mold is opened by the injection molding machine, and the product is ejected from the mold by the ejection system of the injection molding machine. In this way, a product separated from the water gap is obtained.

[0033] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model. Any equivalent structure or equivalent process conversion using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
