Water Pump Foam Mold

Abstract

The invention discloses a water pump foam mold, which comprises an upper mold and a lower mold, the upper mold is divided into a first inner core and a first cavity, the first inner core is equally divided into four first movable blocks, and each first A movable block is divided into an upper layer and a lower layer that can be detachably connected, the lower mold is divided into a second inner core and a second cavity, and the second inner core is divided into a central pentagonal block and five surrounding pentagonal blocks. The second movable block, the second movable block is divided into upper, middle and lower layers; the part of the lower mold corresponding to the connection section is divided into two sections along the vertical line of the water inlet flange, respectively connected to the water inlet flange and the corresponding part of the ring section ; The screw holes are made in the way of core pulling on the upper mold or the lower mold. The mold made by the invention can be molded at one time without being divided into three pieces for bonding like the original process, which solves the problem of bonding after the foam product is produced, and avoids the change of the geometric shape of the foam product during the bonding process. The accuracy of the size is ensured, and the screw holes are formed at one time, eliminating the need for subsequent processing of holes.

Description

technical field [0001] The invention relates to a mold, in particular to a water pump foam mold. Background technique [0002] The current water pump lost foam mold is a process plan that divides the product into three pieces to make the mold. Its characteristics: 1. It is necessary to bond the three pieces of foam products produced by the mold together. The technical requirements for workers are relatively high, and special glue is required; 2. During the bonding process, there are some places that are not bonded due to carelessness. If it is in place, it will cause cracks and dimensional errors in the casting product, and it will become a scrap product; 3. It is easy to cause the geometric shape of the foam product to deform; 4. The production efficiency of casting is low. [0003] In addition, the screw holes on the flanges of the water inlet and outlet are all made in the later stage, and the process of continuing to process holes is required.
