Mould for one-piece base

Abstract

The invention discloses a die of a combined base. The die comprises a die holder, a lower die plate, an upper die plate, a left die plate and a right die plate, wherein a plurality of round holes are formed in the upper die plate; a core die is arranged in each round hole and comprises a middle core rod, an intermediate sleeve and an outer cover die; the inner side of a ring-shaped step concaves upwards to form a ring-shaped inner groove used for forming a first step of an outer ring of the combined base; the contact surface between the lower die plate and a semicircular notch is the step surface of a third step of the outer ring of the combined base. The die has the advantages that as the first step of the outer ring of the combined base is formed by the ring-shaped inner groove, the precision is high, size changes are avoided, and the mounting verticality of a filter casing is ensured; a second step of the outer ring of the combined base is determined by the outer cover die, is even in surface, and is suitable for mounting of a sealing ring; as the parting surface of the die is arranged on the third step of the outer ring of the combined base, assembly cannot be influenced.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for a conjoined base. Background technique [0002] In the water purification equipment, water enters from one end and flows out from the other end. Only one filter device may be connected, or multiple filter devices may be connected. Each filter device includes a base and a filter cover, and the base includes a base, The inner ring, the middle ring, the outer ring, the water inlet hole and the water outlet hole, and the outer ring is divided into the first step, the second step and the third step. The filter cover is set on the first step, which determines the installation verticality of the filter cover. , the bottom surface of the filter cover is installed on the step surface of the second step. The flatness here determines whether the water seeps or not. Generally, a sealing ring is required here. The bottom of the third step is the base, which is the transition area. It does not directly af...

AI Technical Summary

Problems solved by technology

[0003] If multi-channel filtration is required, two adjacent filter devices are generally connected through metal joints, which has many parts, high cost, and many leakage safety hazards; if integrated molding is used for injection molding, the setting of the parting surface has a great impact on the quality. great influence
