[0033] Example

[0034] like Figure 1-2 The filter element 80 of the water purifier shown is in the shape of a stepped cone, with a plurality of conical protrusions 801 circumferentially arranged inside the filter, a filter slit 802 connecting the inside and the outside is opened between two conical protrusions 801, and ribs 803 along the height direction are arranged inside and outside the filter.

[0035] Reference Figure 3-5 As shown, the utility model discloses a molding die for a spliced ​​core, comprising a panel 10, an upper pad 20, an upper movable mold 30, a lower fixed mold 40, a lower pad 50, an ejector plate 60 and a bottom plate 70 from top to bottom, the upper movable mold 30 is embedded with an upper mold core 301, a stepped groove 3011 is opened at the bottom of the upper mold core 301, and a plurality of external molding grooves 3012 are arranged on the inner surface of the groove 3011, the lower fixed mold 40 is embedded with a lower mold core 401, and a core is arranged on the lower mold core 401. When the mold is closed for injection molding, the upper mold core 301 and the lower mold core 401 are closed, the groove 3011 covers the core for molding the main body of the filter element 80, and the external molding groove 3012 is used for molding the rib plate 803 on the outer surface of the filter element 80.

[0036] Reference Figure 5-8As shown, the core includes a top cover 404, a plurality of cylinders 403 and a base 402 from top to bottom. A square plug 4041 is arranged at the bottom of the top cover 404. A fixing groove is provided on the base 402. The plug 4041 passes through the cylinder 403 downwards in sequence and is installed in the fixing groove. A triangular protrusion 4031 and a plurality of inner molding grooves 4032 are arranged circumferentially on the circumferential outer side surfaces of the top cover 404 and the cylinder 403. Before mold closing and injection molding, the plug 4041 of the top cover 404 passes through the cylinder 403 downwards in sequence and is fixed on the base 402 to form a core. The triangular protrusion 4031 and a plurality of inner molding grooves 4032 are arranged circumferentially on the circumferential outer side surfaces of the top cover 404 and the cylinder 403, respectively, for forming the conical protrusion 801 and the rib plate 803 of the inner side wall of the filter element 80. The diameter of the cylinder 403 increases from top to bottom, and the base 402 can slide through the lower fixed mold 40 and be installed on the lower pad 50, so that the inner wall of the formed filter element 80 is stepped. In this embodiment, the cylinder 403 includes two pieces, and the height of the two cylinders 403 is consistent. The two cylinders 403 and the top cover 404 are used to form three steps of the inner wall of the filter element 80, and the height of each step is consistent. Furthermore, a plurality of triangular sheets are further arranged on the top cover 404, and the triangular sheets are used to form the conical filter seam 802 at the bottom of the filter element 80.

[0037] Reference Figure 3 As shown, the lower fixed mold 40, the lower pad 50 and the ejector plate 60 are equipped with a locking machine 501, and the locking machine 501 enables the filter element 80 to fall off from the core. Specifically, the locking machine 501 includes a push plate, a limit guide block and a spring block. The lower end of the push plate is fixed to the ejector plate 60. The limit guide block has a guide groove for the push plate to move. The spring block is placed on the side of the lower fixed mold 40. When the mold is opened, the spring block is placed outside the lower fixed mold 40. The ejector plate 60 pushes the push plate spring block upward to drive the lower fixed mold 40 to move upward. Since the base 402 is fixed on the lower pad 50, the lower fixed mold 40 pushes the product upward to fall off from the core when the core is not moving. When the lower fixed mold 40 moves upward until the spring block touches the upper end of the limit guide block, the limit guide block pushes the spring block to separate from the push plate, that is, the upper movable mold 30 stops moving upward.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
