AI Technical Summary
During injection molding of HDPE monolayer products, T-type products deform at the socket because the molecular chain orientation is opposite to the filling direction, which is difficult to solve effectively with existing technology.
By employing a temperature control system and core structure, the temperature at the end of the filling is increased through heating channels, reducing the degree of molecular chain orientation, decreasing stress, and improving deformation.
Without significantly altering the mold design, this method effectively improves the deformation problem of the socket in tee-type products, thereby enhancing product quality.

[0023] Combined with appendix Figures 1 to 5 As shown, this embodiment discloses a cooling system structure that can improve the deformation of the same-layer drainage socket of a tee-type fitting. It includes a temperature control system, a product cavity, and a core structure. The temperature control system includes a heating channel 2 and a cooling water path 1. The cooling water path 2 is distributed around the product cavity, and the heating channel 2 passes through the socket core 12. The cooling water path 2 is used to cool the product cavity, and the heating channel 2 is used to increase the temperature at the filling end, reduce the degree of molecular chain orientation, reduce the stress in the area after filling, and thus improve the deformation of the area.
[0024] The core structure includes a socket slider 11, a support slider 10, a socket core 12, and a support core 13, with the socket core 12 and support core 13 located within the product cavity. During mold closing, the socket core 12 and support core 13 come into contact. The socket core 12 is fixed to the socket slider 7, and the support core 13 is fixed to the support slider 10. The socket slider 11 and support slider 10 are slidably mounted on the moving mold frame 14.
[0025] The product cavity is located within the fixed mold frame 5 and the moving mold frame 14 of the mold. The product cavity is connected to the runner. The runner includes a main runner 7 and an annular runner 9. One end of the main runner 7 is connected to the gate and the other end is connected to the annular runner 9. The annular runner 9 is connected to the product cavity.
[0026] A first connecting rod 3 is fixedly connected to the socket slider 11, and both ends of the first connecting rod 3 are slidably connected to the guide rails on the socket inclined guide plate 4.

Figure 8 , Figure 9 Variation 21 in the text.
[0029] Before production, cooling water channel 1 is connected and circulated with room temperature cooling water; then heating channel 2 is connected to raise the temperature at the filling end. Heating channel 2 can be heated by heating bars, steam, or hot oil, ensuring that the temperature at heating channel 2 is not lower than 100°C. This raises the temperature at the filling end, reduces the degree of molecular chain orientation, and reduces the stress in this area after filling, ensuring that the socket of the same-layer tee product does not deform.
