The inner wall of the flow-guiding arc plate 201 is provided with a flow-dividing arc plate 202, and the flow-slowing arc plate 203 is provided on the outer wall of the flow-dividing arc plate 202. The flow-slowing arc plate 203 is connected to the flow-guiding arc plate 201 through the flow-dividing arc plate 202.

[0038] Specifically, the flow guiding arc plate 201 and the flow splitting arc plate 202 are an integral structure. The flow guiding arc plate 201 is an arc-shaped elastic curved surface structure, and the flow splitting arc plate 202 is a conical structure. The flow slowing arc plate 203 is disposed at the bottom of the flow splitting arc plate 202 and is distributed in a linear array. The flow slowing arc plate 203 is provided with a plurality of flow slowing grooves 204 inside. The flow slowing grooves 204 are distributed in a linear array on the inner wall of the flow slowing arc plate 203, and the flow slowing arc plate 203 is wavy in shape.

[0039] Specifically, the outer wall of the flow guide plate 201 is provided with a connecting patch 211, the connecting patch 211 is a circular elastic curved surface structure, and the connecting patch 211 is in contact with the inner wall of the injection hole 102.

[0042] To address the issue that the rapid flow of molten plastic may cause defects such as ripples, flow marks, and silver streaks on the surface of plastic products, affecting their appearance and quality, the technical solution implemented here is as follows (for reference). Figures 3 to 4The flow guiding arc plate 201 and the flow dividing arc plate 202 are integral structures. The flow guiding arc plate 201 is an arc-shaped elastic curved surface structure, and the flow dividing arc plate 202 is a conical structure. The flow slowing arc plate 203 is disposed at the bottom of the flow dividing arc plate 202 and is distributed in a linear array. The flow slowing arc plate 203 has a plurality of flow slowing grooves 204 inside, which are distributed in a linear array on the inner wall of the flow slowing arc plate 203. The flow slowing arc plate 203 is wavy in shape. The flow dividing arc plate 202 diverts the molten plastic guided by the flow guiding arc plate 201, so that the molten plastic flows into the flow slowing arc plate 203 respectively. With the help of the flow slowing grooves 204 on the inner wall of the flow slowing arc plate 203, the flow rate of the molten plastic can be slowed down, avoiding defects such as ripples, flow marks, and silver streaks on the surface of plastic products caused by the rapid flow of molten plastic, which would affect the appearance and quality of the product.

By pressing the pushing connecting plate 209, the elastic clamping plate 206 is squeezed, causing the positioning sleeve 205 to move towards the center. Then, the positioning sleeve 205 is placed inside the injection hole 102. With the help of the elastic clamping plate 206, the positioning sleeve 205 is in close contact with the inner wall of the injection hole 102, thereby installing the flow slowing mechanism 2 inside the injection hole 102. Moreover, the flow slowing mechanism 2 can be installed on the inner wall of injection holes 102 of different sizes, which can slow down the flow rate of molten plastic inside injection holes 102 of different sizes.

[0045] Based on the above embodiments, it can be concluded that by pressing and pushing the connecting plate 209, the elastic clamping plate 206 is squeezed, causing the positioning sleeve 205 to move towards the center. Then, the positioning sleeve 205 is placed inside the injection hole 102. With the help of the elastic clamping plate 206, the positioning sleeve 205 is made to make close contact with the inner wall of the injection hole 102. The slow flow mechanism 2 can be installed inside the injection hole 102. Then, the flow diversion arc plate 202 is used to divert the molten plastic guided by the flow guiding arc plate 201, so that the molten plastic flows into the slow flow arc plate 203 respectively. With the help of the slow flow groove 204 set on the inner wall of the slow flow arc plate 203, the flow rate of the molten plastic can be slowed down, avoiding the defects such as ripples, flow marks, and silver streaks on the surface of the plastic product caused by the fast flow rate of the molten plastic, which would affect the appearance and quality of the product.
