[0030] Example

[0031] like Figure 1 The water purifier housing 70 shown in the figure has a hollow interior and an open end surface, and the outer surface of the water purifier housing 70 is smooth and has no marks.

[0032] Reference Figure 2-7As shown, the utility model discloses a molding die for a water purifier housing 70, comprising a panel 10, a pad 20, an upper movable mold 30, a lower fixed mold 40, an ejector plate 50 and a bottom plate 60 from top to bottom, a cross-shaped cavity 301 is opened at the bottom of the upper movable mold 30, a cross-shaped groove is opened at the lower fixed mold 40, a core 401 is arranged in the middle of the groove, four side molding mechanisms are circumferentially installed around the core 401 on the side surface of the lower fixed mold, and the side molding comprises a side slider 402 and a driving hydraulic cylinder 403, and the driving hydraulic cylinder 403 drives the side slider 402 to approach or leave the core 401. Specifically, when the mold is closed, the four driving hydraulic cylinders 403 respectively drive the side sliders 402 to approach the core 401, the upper movable mold 30 and the lower fixed mold 40 are closed, and the cavity 301 covers the four side sliders 402 and the core 401. The hot melt adhesive enters the gap between the side sliders 402 and the core 401 and the gap between the core 401 and the bottom of the cavity 301 from the glue inlet of the panel 10, and the water purifier shell 70 is formed after cooling, wherein the upper movable mold 30 is embedded with a molding block 303 at the bottom of the cavity 301, and the molding block 303 is provided with a protrusion downward, which abuts against the upper surface of the core 401 to form the structure of the upper surface of the water inlet shell. The core 401 has inclined guide grooves on both sides, and a push block 501 is slidably arranged in the guide groove. The lower end of the push block 501 passes through the lower fixed mold 40 to connect the ejector plate 50. Specifically, when the mold is opened, the upper movable mold 30 and the lower fixed mold 40 are separated, and the cavity 301 and the side slider 402 and the core 401 are separated. The four driving hydraulic cylinders 403 drive the side slider 402 to leave the core 401, and the purifier shell is covered on the core 401. The ejector plate 50 pushes the push block 501 upward to push the purifier shell off the core 40 1 falls off; further, the lower fixed mold 40 is further provided with push plates 502 on both sides of the core 401, and a push rod is installed on the ejector plate 50. The upper end of the push rod can slide through the lower fixed mold 40 to connect the push plate 502. The ejector plate 50 pushes the ejector block 501 upward and pushes the push plate 502 upward from the lower edge of the water purifier to push the product off the core 401, which further plays a role in assisting demoulding, that is, realizing the molding and demoulding of the product, avoiding the use of the traditional ejector ejection method to realize the demoulding of the product.

[0033] Reference Figure 2-7As shown, a plurality of wedge blocks 302 are installed around the cavity 301 at the bottom of the upper movable mold 30, and the side slider 402 is provided with an inclined guide hole. When the upper movable mold 30 and the lower fixed mold 40 are closed, the top block 501 passes through the guide hole. In this embodiment, each side slider 402 is provided with two guide holes. When the inclined wedge block 302 is inserted into the guide hole, the wedge block 302 pushes the side slider 402 close to the core 401, so as to avoid inconsistent thickness or scrapping of the water purifier housing 70 due to the slider not being moved into place. Furthermore, the side molding mechanism further includes a limit switch 404, which includes a moving rod, a first sensor and a second sensor. One end of the moving rod is fixed to the side slider 402, and the other end is placed between the first sensor and the second sensor. The first sensor is used to limit the limit position of the hydraulic cylinder 403 driving the side slider 402 close to the core 401 when the mold is closed, and the second sensor is used to limit the limit position of the hydraulic cylinder 403 driving the side slider 402 away from the core 401 when the mold is opened, and is used to control the extension and retraction of the hydraulic cylinder 403 to achieve an automated effect.

[0034] In addition, convex strips are arranged on both sides of the side slider 402 in the groove, and sliding grooves are opened on both sides of the side slider 402. The sliding grooves and the convex strips cooperate to enable the side slider 402 to slide in the groove. The setting of the convex strips makes the side slider 402 slide more smoothly in the sliding groove.

[0035] 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.
