Description

Technical Field

There is usually a hollow part for accommodating a filter element in water purifier parts, and it is generally formed by pouring with a hollow molding die during production.

[0003] For example, Chinese Patent Application CN211137981U discloses an inner tube molding die for a water purifier, which includes a first cavity tube, a second cavity tube and a third cavity tube distributed in sequence from bottom to top. A plurality of clamping plates are symmetrically distributed along the axis at the top of the third cavity tube; by providing an inner tube molding die for a water purifier composed of the first cavity tube, the second cavity tube, the third cavity tube and the clamping plates, two annular clamping grooves are opened on the outer wall of the first cavity tube, and through holes are opened between the annular clamping grooves for installing a feeding mechanism. A material tube is inserted into the through holes to feed materials into the tube cavity for cooperation with the inner mold core to form an inner tube of the water purifier, and it gradually narrows from the second cavity tube to the third cavity tube.
