Description

Technical Field

[0001] This utility model belongs to the field of centrifugal casting mold technology, specifically relating to a centrifugal casting mold for manufacturing bimetallic brake drums. Background Technology

[0002] Bimetallic brake drums are high-performance braking system components that combine the advantages of different metal materials to improve braking efficiency and durability. Bimetallic brake drums are typically made of two composite metal materials. During manufacturing, the centrifugal casting mold used for bimetallic brake drums is a key piece of equipment in the centrifugal casting process. The centrifugal casting mold is usually designed with a specific shape to contain liquid metal and distribute it evenly under centrifugal force. For example, Chinese patent discloses a centrifugal casting mold for bimetallic brake drums (authorization announcement number CN222492088U). This patented technology can effectively reduce the deformation of bimetallic brake drums during high-temperature centrifugal casting, providing a relatively good foundation for subsequent processing.

[0003] However, the existing centrifugal casting molds for bimetallic brake drums still have some shortcomings in practical applications that need to be improved, such as:

[0004] 1. The steel shell of the metal brake drum is time-consuming and laborious to install and remove, which is not conducive to the convenience of use. The stability of the fixed position is poor, the compatibility with different bimetallic brake drums is low, which is not conducive to the compatibility range of centrifugal casting molds, and the flexibility of use is low.

[0005] 2. The centrifugal casting mold completely covers the steel outer shell of the metal brake drum, which affects the heat dissipation of the metal brake drum after casting and is detrimental to the processing efficiency of the metal brake drum. Therefore, those skilled in the art have provided a solution to address the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a centrifugal casting mold for manufacturing bimetallic brake drums, which can solve the problems mentioned in the background art.

[0007] The specific technical solution adopted in this utility model is as follows:

The first fixing member is located on one side of the shaft seat, the fixing screw is located at the outer end of the first fixing member, and the second fixing member is located at one end of the fixing screw. Nuts are installed at both ends of the fixing screw, and a steel outer shell for a metal brake drum is provided inside the second fixing member.

[0009] Both the first fixing member and the second fixing member include a positioning ring. A fixing ring is provided on one side of the positioning ring. An adjusting screw is provided on the outer side of the positioning ring. A right-angle locking block is provided at the inner end of the adjusting screw. A screw hole is provided on one side of the fixing ring.

[0010] The present invention is further configured such that: a slot is provided on the outer side of the positioning ring; the bearing seat includes a bearing plate; a shaft rod is provided on one side of the bearing plate; a retaining plate is provided on the other side of the bearing plate; a hook is provided at one end of the inner side of the retaining plate; and a fixing screw is provided at the other end of the outer side of the retaining plate.

[0011] The present invention is further configured such that: the position of the fixing screw corresponds to that of the screw hole, the outer end of the fixing screw slides in the inner position of the screw hole, and the nut is located in the outer position of the fixing ring.

[0012] The present invention is further configured such that: the outer end of the adjusting screw rotates to the outer position of the positioning ring, the inner end of the adjusting screw rotates to the outer position of the right-angle block, the right-angle block slides to the inner position of the positioning ring via the adjusting screw, and the steel outer shell of the metal brake drum is fixed to the inner position of the positioning ring via the right-angle block.

[0013] The present invention is further configured such that: the slot and the hook are positioned correspondingly, the hook is located inside the slot, the plate is located outside the positioning ring, the inner end of the fixing screw passes through the plate located outside the positioning ring, and the plate is fixed to the outer position of the positioning ring by the fixing screw.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses a centrifugal casting mold for manufacturing bimetallic brake drums. The first and second fixing components are assembled and disassembled by a fixing screw, which increases the loading and unloading speed of the steel shell of the metal brake drum but reduces the ease of use. The steel shell of the metal brake drum is fixed by adjusting the screw and the right-angle locking block, which improves the stability of the fixation and adapts to the processing operations of different bimetallic brake drums. This expands the adaptability of the centrifugal casting mold and improves the flexibility of use.
