[0003] As shown in the attached diagram of the instruction manual. Figure 1 As shown, the base of the stop valve has a complex structure, making it difficult to mold.
[0004] Based on this, this utility model designs a mold for forming a water stop valve base for water purifier production to solve the above problems. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a mold for forming a water stop valve base for water purifier production.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The moving mold has an upper mold core fixedly installed inside, and the fixed mold has a lower mold core fixedly installed inside.
[0009] A two-out forming mechanism is provided between the upper mold core and the lower mold core. The two-out forming mechanism includes a fixed forming component and a downward linkage translational mold forming component.
[0010] The fixed molding component, the downward-pressing linkage translational mold molding component, the upper mold core and the lower mold core cooperate with each other to form two cavities for molding the base of the water stop valve; when the upper mold core and the lower mold core are closed, the upper mold core drives the downward-pressing linkage translational mold molding component to approach the fixed molding component to cooperate in molding the base of the water stop valve; when the upper mold core and the lower mold core are separated, the upper mold core drives the downward-pressing linkage translational mold molding component away from the fixed molding component to simultaneously separate and demold.
[0011] The lower end of the fixed mold is equipped with a uniform demolding mechanism for evenly displacing the injection-molded stop valve base from the stop valve base.
[0012] Furthermore, the fixed molding assembly includes an upper main groove, an upper inner groove, a lower main groove, a lower inner groove, a protrusion, and a cylindrical block.

The horizontal moving slide is mounted on the fixed mold, and the pressing linkage component is provided between the moving end of the horizontal moving slide and the moving mold.
[0017] Furthermore, the pressing linkage assembly includes a slanted insert rod and a slanted slot. The slanted insert rod is fixedly connected to the moving mold, and the moving end of the horizontal moving slide is provided with a slanted slot for inserting into the slanted insert rod. The side of the fixed mold is also provided with a clearance groove for avoiding the slanted insert rod.
[0018] Furthermore, the uniform demolding mechanism includes an ejector pin fixing plate and ejector pins.

[0041] The pressing-linkage translational molding assembly 42 includes a pressing-linkage translational slide, a rod 427, and a side push block 428.

The rod 427, the side push block 428, and the arc groove cooperate to form the extension tube 26 of the water stop valve base 2.
[0042] The pressing linkage type translation slide includes a horizontal moving slide and a pressing linkage component. The horizontal moving slide is installed on the fixed mold 11, and the pressing linkage component is provided between the moving end of the horizontal moving slide and the moving mold 10.
[0043] Please see Figure 6 and Figure 7 The horizontal moving slide includes an upper limit block 421, a lower limit block 422, a T-shaped slide plate 423, and a fixing block 424. The upper limit block 421 and the lower limit block 422 are both fixedly connected to the fixed mold 11. The T-shaped slide plate 423 is located between the upper limit block 421 and the T-shaped slide plate 423 and is slidably connected to them.

Through the cooperation of the inclined insert rod 425 and the inclined slot 426, the side push block 428 and the insert rod 427 are also gradually reset and disengaged from the water stop valve base 2, so that the extension tube 26 of the water stop valve base 2 is completely exposed to the outside, which facilitates the demolding operation of the water stop valve base 2.
[0046] Please see Figure 6 and Figure 8 The uniform demolding mechanism 3 includes an ejector pin fixing plate 31 and ejector pins 32.

When the water stop valve base 2 is formed, the moving mold 10 and the fixed mold 11 separate. At this time, the ejector pin fixing plate 31 is pushed upward by the hydraulic actuator or the pneumatic actuator, so that the ejector pins 32 are pushed upward from the bottom of the wing plates 23 of the water stop valve base 2, so that the water stop valve base 2 after being formed is uniformly subjected to force and demolded.
