[0017] The following specific implementation contents provide a variety of different embodiments or examples for implementing the utility model. Of course, these are only embodiments or examples and are not intended to be limiting. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0018] The following figures and specific implementations further describe the utility model: Figure 1-Figure 5A hot runner flip-chip mold for forming a shower cover shown in the figure includes a movable mold plate 1 and a fixed mold plate 2, a movable mold core 3 is arranged in the movable mold plate 1, a fixed mold core 4 is arranged in the fixed mold plate 2, an arc-shaped water channel 5 is arranged at the bottom end of the movable mold core 3, a movable mold water inlet 6 and a movable mold water outlet 7 are arranged on the movable mold plate 1, one end of the arc-shaped water channel 5 is connected to the movable mold water inlet 6, and the other end of the arc-shaped water channel 5 is connected to the movable mold water outlet 7, a planar spiral water channel 8 is arranged at the bottom end of the fixed mold core 4, a fixed mold water inlet 9 and a fixed mold water outlet 10 are arranged on the fixed mold plate 2, one end of the planar spiral water channel 8 is connected to the fixed mold water inlet 9, and the other end of the planar spiral water channel 8 is connected to the fixed mold water outlet 10.

[0019] In the utility model, an arc-shaped water channel 5 is provided on the movable mold core 1, and a plane spiral water channel 8 is provided on the fixed mold core 3, so that the water cooling area can be increased, and the cooling is uniform at the same time, and the movable mold core 1 and the fixed mold core 2 can be quickly cooled, thereby improving the demoulding efficiency of the product, shortening the production cycle, reducing the production cost, and improving the production efficiency.

[0020] See also Figure 2-Figure 3 As shown, the water transport path of the movable mold plate 1 and the movable mold core 3 is: the cooling water enters from the movable mold water inlet 6, that is, from A1, comes out from A2 and enters the arc water channel 5 of the movable mold core 3, flows from A3 to B1, and then enters B2 of the movable mold plate 1 from B1, and finally flows out from the movable mold water outlet (B3) for circulation.

[0021] Of course, a plurality of arc-shaped water channels 5 can be provided according to the requirements of the mold structure, and a plurality of corresponding movable mold water inlet channels 6 and movable mold water outlet channels 7 can be provided.

[0022] See also Figure 4-Figure 5 As shown, the water transport path of the fixed mold plate 2 and the fixed mold core 4 is: the cooling water enters from the fixed mold water inlet 9, that is, from C1, comes out from C2 and enters the plane spiral water channel 8 of the fixed mold core 4, flows from C3 to D1, and then enters D2 of the fixed mold plate 2 from D1, and finally flows out from the fixed mold water outlet 10 (D3) to circulate.

[0023] It should be noted that the water channel area of ​​the plane spiral water channel 8 is larger than that of the arc water channel 5, so the cooling effect of the plane spiral water channel 8 is better than that of the arc water channel 5. However, since the fixed mold plate 2 has a pin passing through it, it is difficult to set the plane spiral water channel 8. Therefore, the arc water channel 5 can satisfy both the cooling effect and the design requirements of the mold.

[0024] A first sealing ring installation groove is arranged at intervals on one side where the movable mold plate 1 cooperates with the movable mold core 3, and a first sealing ring 22 is arranged in the first sealing ring installation groove. When the movable mold core 3 is installed with the movable mold plate 1, the arc water channel 5 is located in the two first sealing rings 22; thereby, the sealing performance of the cooling water when flowing in the arc water channel 5 can be improved.

[0025] A second sealing ring installation groove is provided on one side where the fixed mold plate 2 cooperates with the fixed mold core 4, and a second sealing ring 32 is provided in the second sealing ring installation groove. When the fixed mold core 4 is installed with the fixed mold plate 2, the planar spiral water channel 8 is located in the second sealing ring 32, thereby improving the sealing performance of the cooling water when flowing in the planar spiral water channel 8.

[0026] See also Figure 1 As shown, it also includes a movable mold fixed bottom plate 41, a nozzle plate 42 and a mold foot 43 which are arranged in sequence, two mold feet 43 are arranged at intervals and fixed on the movable mold plate 1, an ejector plate 44 is arranged between the nozzle plate 42 and the movable mold plate 1, a plurality of springs 46 are arranged between the ejector plate 44 and the movable mold plate 1, an ejector plate 44 is provided with an ejector for ejecting the injection molded product, and a fixed mold fixed bottom plate 45 is fixed to the outer end of the fixed mold plate 2.

[0027] Furthermore, an upper pull rod 51 is provided on one side of the ejector plate 44, and an upper hook 52 is provided at the lower end of the upper pull rod 51. A lower pull rod 53 is provided on one side of the fixed template 2, and a lower hook 54 is provided at the upper end of the lower pull rod 53. When the movable template 1 and the fixed template 2 are opened, the upper hook 52 and the lower hook 54 cooperate with each other to press against each other.

[0028] When opening the mold, the movable mold plate 1 is separated from the fixed mold plate 2, and after the movable mold plate 1 and the fixed mold plate 2 are separated to a certain distance, the upper hook 52 of the upper pull rod 51 and the lower hook 54 of the lower pull rod 53 are pressed against each other. At this time, the fixed mold plate 2 and the lower pull rod 53 and the lower hook 54 remain stationary, and the movable mold plate 1 performs the mold opening action, and then the upper hook 52 on the upper pull rod 51 drives the ejector plate 44 to move, and the product is ejected by the ejector on the ejector plate 44.
