[0031] The embodiment of the present utility model provides a water spray cover plate forming die, such as Figure 3-8 As shown, including:

[0032] Front mold assembly 100;

[0033] rear mold assembly 200;

[0034] The front mold core 300 is provided with a first runner trough 310 and two first molding parts 320 provided at both ends of the first runner trough 310;

[0035] The rear mold core 400 is provided with a second runner trough 410 and two second forming parts 420 provided at both ends of the second runner trough 410;

[0036] The inclined ejector assembly 500 is fixed to the front mold assembly 100. The inclined ejector assembly 500 can pass through the front mold core 300 and abut the rear mold core 400. The inclined ejector assembly 500 includes a forming member 510 for forming the undercut 15 of the water spray cover 10. The forming member 510 is provided with a spring 520 at one end close to the front mold assembly 100.

The forming member 510 is provided with a positioning member 530, and the front mold core 300 is provided with a limiting groove 330 that cooperates with the positioning member 530.

[0037] The first runner trough 310 and the second runner trough 410 are used to place a two-part runner for simultaneously molding two water spray cover plates 10. The first molding part 320 and the second molding part 420 are located on both sides of the first runner trough 310 and the second runner trough 410. The inclined top assembly 500 is a movable assembly that can move when the mold is opened and closed to ensure that the shape of the undercut 15 of the water spray cover plate 10 is formed. The positioning member 530 cooperates with the limiting groove 330 to limit the movement of the inclined top assembly 500. The design of the inclined top assembly 500 enables the undercut 15 to be molded in a limited mold space and can meet the requirements of molding two water spray cover plates 10 in the mold at the same time.

[0038] The working principle of this utility model is as follows:

[0039] When the mold is closed, under the action of the rear mold, the spring 520 is compressed, and the molded part 510 moves to a position close to the first molding part 320 and the second molding part 420, and the material is injected into the first molding part 320 and the second molding part 420, and two water spray cover plates 10 are formed at the same time; when the mold is opened, under the action of the elastic force of the spring 520, the molded part 510 naturally pops out a certain distance and escapes from the undercut 15; after the finished product is taken out, the mold is closed, and the rear mold core 400 presses the inclined top assembly 500 back to its original position and prepares for the next injection molding process.

[0040] In some embodiments, the molding member 510 includes an inclined portion 540 and a third molding portion 550 , and an undercut groove 560 is defined on the third molding portion 550 .

[0041] The inclined portion 540 is angled relative to the horizontal. This design facilitates easier separation of the molded part 510 from the formed water spray cover plate 10 structure when the mold is opened. The inclined portion 540 reduces material adhesion, thereby improving production efficiency and reducing scrap. The third forming portion 550 is connected to the inclined portion 540. The undercut groove 560 of the third forming portion 550 is used to form the undercut 15 of the water spray cover plate 10.

[0042] Furthermore, the positioning member 530 is located at an end of the inclined portion 540 away from the third forming portion 550 .

[0043] In some embodiments, the first forming portion 320 includes a first forming block 340 for forming the middle groove 11 and a flange groove 350 for forming the flange 12. The first forming block 340 is used to form the middle groove 11 of the water spray cover plate 10, and the flange groove 350 is used to form the flange 12 of the water spray cover plate 10.

[0044] Furthermore, the limiting groove 330 is located on a side of the front mold core 300 close to the front mold assembly 100 .

[0045] After the lift assembly 500 pops out a certain distance, the lift assembly 500 stops popping out due to the cooperation between the limiting groove 330 and the positioning member 530 .

[0046] Furthermore, the limiting groove 330 includes a limiting portion 360 for limiting the positioning member 530 and a through-slot portion 370. The through-slot portion 370 is used to ensure that the molded member 510 can pass through.

[0047] In some embodiments, the second molding unit 420 includes a second molding block 430 for molding the through-groove 13 and a third molding block 440 for molding the retaining groove 14. The second molding block 430 is used to mold the through-groove 13 of the water spray cover plate 10. The third molding block 440 is used to mold the retaining groove 14 of the water spray cover plate 10.

[0048] In some embodiments, the positioning member 530 is a limiting rod that passes through the forming member 510 and is fixed to the forming member 510 , and the limiting rod cooperates with the limiting groove 330 to position the forming member 510 .

[0049] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
