The semi-finished shower back cover 1' includes a semi-finished shower back cover body 2', a liquid inlet channel 3' disposed on the top surface of the semi-finished shower back cover body 2', and a broken thread portion 4' disposed on the semi-finished shower back cover body 2' and located in the liquid inlet channel 3'.

[0004] The liquid passage includes a liquid passage main hole 5', which is disposed on the top surface of the semi-finished shower head back cover body 2' and located below the liquid inlet channel 3'; and several liquid passage side holes 6', which are disposed on the top surface of the semi-finished shower head back cover body 2' and located around the liquid passage main hole 5'. The liquid passage main hole 5' and the liquid passage side holes 6' are both connected to the liquid inlet channel 3'.

[0005] The broken threaded part 4' is used to connect with the external liquid inlet pipe, and the liquid inlet channel 3' is used to allow the liquid in the liquid inlet pipe to enter the semi-finished shower head back cover body 2' after the broken threaded part 4' is connected with the external liquid inlet pipe.

[0026] Therefore, this utility model provides the following effects and / or advantages:

[0027] 1) The injection molten material is injected into the female mold core through the gating device. The injection molten material passes through the male mold core, female mold core, first mold core, second mold core, and third mold core to form the semi-finished shower head back cover body, liquid inlet channel, and broken thread part, thereby forming the semi-finished shower head back cover. After cooling, the right plate separates from the female mold plate, thereby driving the third mold core to move to the right, thereby causing the core pulling part to drive the two sliders to move closer to each other, and then the first mold core and the second mold core move closer to each other. The female mold plate separates from the male mold plate, thereby separating the female mold core from the male mold core, and removing the semi-finished shower head back cover from the male mold core.

[0028] The first water-cooling component is used to quickly and evenly remove the heat of the injection molten material in the male mold core during the molding of the semi-finished shower head back cover through the male mold core, female mold core, first mold core, second mold core, and third mold core, thereby efficiently molding a semi-finished shower head back cover with a stable shape and qualified quality. The second water-cooling component is used to quickly and evenly remove the heat of the injection molten material in the female mold core during the molding of the semi-finished shower head back cover through the male mold core, female mold core, first mold core, second mold core, and third mold core, thereby efficiently molding a semi-finished shower head back cover with a stable shape and qualified quality.

[0029] In summary, the above-mentioned semi-finished shower head back covers can be formed in one step, and rapid and uniform cooling can be achieved during the forming process. This allows for the efficient formation of semi-finished shower head back covers with stable shapes and qualified quality, eliminating the need for multiple processing steps, thus increasing production speed and facilitating mass production.

[0030] 2) The combination of the limiting plate, limiting rod, and limiting groove can limit the movement of the right plate to the right, thereby improving the structural strength of the injection mold; the protective blocks are used to buffer the right plate when it approaches the mother plate, preventing hard contact between the right plate and the mother plate and reducing vibration of the injection mold.
