Embodiment Construction

[0030] In FIG. 1 a model 1 of a casting mold for sand casting to manufacture a brake caliper 13 of a disc brake is depicted, which model comprises two parallel bearing points 4, 5 arranged at a distance from each other, said bearing points respectively There is a bearing bore for receiving a sliding sleeve, wherein one bearing point 4 arranged on the right or left protrudes in the axial direction relative to the other bearing point. In Figure 1, the longer support point 4 is at Figure 1a visible in the Figure 1b The left-hand arrangement of the longer bearing point 4 is described.

[0031] In addition, the casting mold has a not-shown multi-part flask, in which a cavity is formed in a sand bed by a two-part mold 1 .

[0032] In order to form the bearing points 4, 5 and the receiving chamber 8, the mold core 2 shown in detail in FIG. Functional parts of the type brake, such as the hold-down device, the receiving chamber has a rod socket 10 on the top, which is used to acco...

Abstract

The invention relates to a casting mold for sand casting to produce a brake caliper (13) of a disc brake, said casting mold having a receiving chamber and two bearing points (4, 5) arranged in parallel and at a distance from each other , the support points each have a support hole for receiving a sliding sleeve, wherein one support point arranged on the right or left protrudes in the axial direction relative to the other support point, the casting mold is multi-part A flask, a mold (1) for forming a cavity in a sand bed and a core (2) for forming said bearings (4, 5) and receiving chambers, said casting mold is constructed such that the mold (1 ) reflecting the two bearing points (4, 5) are formed identically in terms of shape and size.

Description

technical field [0001] The invention relates to a casting mold for sand casting to manufacture brake calipers for disc brakes. Background technique [0002] A brake caliper of a disc brake, in particular a sliding caliper disc brake, is used to receive a functional part, in particular to receive a pressure device positioned in a receiving chamber of the brake caliper which can be closed by a closure cover middle. [0003] The pressing device has a pneumatically or electrically actuated brake lever which, when actuated, presses the brake lining against the vehicle-side brake disc. [0004] In order to be able to move the caliper axially relative to the brake disc, the caliper is supported on guide pins connected to the brake carrier, said guide pins together with sliding sleeves held in the bearing holes of the caliper constitute a sliding bearing. [0005] In this case, one of the slide bearings is designed as a fixed bearing and the other slide bearing as a floating bear...
