Abstract:
Disclosed herein is a mold for manufacturing a housing of a hydraulic unit of an anti-lock brake system for vehicles. The housing has a plurality of bores formed therein such that components, such as a plurality of valves, accumulators, hydraulic pumps, and a driving motor, and a plurality of connection pipes are mounted to the housing through the bores. The mold comprises a lower mold mounted in a stationary frame for defining a housing forming space where the lower part and side parts of the housing are formed, an upper mold mounted in a movable frame disposed on the stationary frame such that the movable frame is vertically moved a predetermined distance, the upper mold covering the upper part of the housing forming space of the lower mold to form the upper part of the housing, lower cores attached to the lower mold such that the lower cores are protruded from the inner lower surface of the lower mold to form the lower-side bores of the housing, an upper core attached to the upper mold for forming the upper-side bores of the housing, and a plurality of side cores disposed at the lower mold such that the side cores move into and out of the housing forming space defined in the lower mold through the lower mold in four directions to form the bores provided at the four sides of the housing. With the mold according to the present invention, a housing having a complicated structure is manufactured through injection molding of a resin material. Consequently, the housing is easily manufactured with increased productivity as compared with the conventional method of manufacturing the housing through an aluminum cutting process. Furthermore, the manufacturing costs of the housing are reduced.

Abstract:
The present invention discloses a hydraulic unit of an anti-lock brake system for vehicles having a housing that is easily manufactured, whereby production efficiency is improved, and thus the manufacturing costs of the housing are reduced. The present invention also discloses a method of manufacturing the same. The hydraulic unit comprises a housing having components that control braking oil pressure supplied to wheels of a vehicle, such as a plurality of valves, accumulators, and hydraulic pumps, mounted thereto, flow channels formed in the housing, the flow channels being connected between the components, and a plurality of pipes connected to each other in the housing. The housing is made of an injected resin material having a plurality of reinforcing members that reinforce the strength of the parts of the housing where the components are mounted to the housing and the pipes are connected to the housing inserted therein. The housing is made of an injected resin material having a plurality of reinforcing members that reinforce strength of the parts of the housing where the components are mounted to the housing and the pipes are connected to the housing inserted therein.
