Embodiment 1

[0028] A kind of damping pulley rubber ring embedding mold, including a pulley 8 with a hub 81 and a pulley 82, characterized in that it also includes an upper pressing device and a lower pushing device; the hub 81 and the pulley 82 are pressed on the upper The lower part of the pressing device is placed in the lower top device; the upper pressing device includes an outer pressing die 2 and an inner pressing die 7, and a limiting sleeve 6 is arranged between the outer pressing die 2 and the inner pressing die 7; The upper pressing device is placed in the gap between the wheel hub 81 and the pulley 82 through the spacer sleeve 6, and the outer die 2 and the inner die 7 are respectively located at the upper ends of the pulley 82 and the wheel hub 81 at the same time; the lower pushing device includes Inner supporting mold 9, outer supporting mold 10, lower supporting mold 11 and upper top cover 12; described wheel hub 81 and pulley 82 are respectively placed on the upper end of i...

Embodiment 2

[0030] A rubber ring embedding mold for a shock-absorbing pulley is similar to Embodiment 1, except that a buffer 16 is provided in the lower jacking device. In this way, the buffer 16 with positioning function is used to replace the spring function in the lower ejecting device, which improves the energy absorption and release ability after being under pressure, solves the disadvantages caused by poor spring buffering to the fitting mold, and ensures Fitting quality of damper pulleys.

Embodiment 3

[0032] A rubber ring embedding mold for a shock-absorbing pulley is similar to Embodiment 2, except that the upper end of the buffer 16 is provided with a connecting sheath 17 to protect the buffer axis. In this way, the use of the connecting sheath 17 not only plays the role of protecting the axis of the buffer 16, but also indirectly stabilizes the lower supporting mold 11 on the upper end of the buffer 16, and at the same time enables the lower supporting mold 11 to achieve axial and radial fixation.

Abstract

The invention relates to a rubber ring embedding mold of a damping belt and an embedding method of the rubber ring embedding mold. The rubber ring embedding mold comprises a belt wheel, an upper pressing device and a lower supporting device, wherein the belt wheel is provided with a wheel hub and a belt wheel which are pressed below the upper pressing device and are arranged in the lower supporting device; the upper pressing device comprises an outer pressing mold and an inner pressing mold which are separately arranged at the upper ends of the belt wheel and the wheel hub at the same time; a stop collar is arranged between the outer pressing mold and the inner pressing mold; the upper pressing device is arranged in a gap between the wheel hub and the belt wheel through the stop collar; the lower supporting device comprises an inner support mold, an outer support mold, a lower support mold and an upper supporting sleeve; the wheel hub and the belt wheel are separately arranged at the upper ends of the inner support mold and the outer support mold; a pin column connecting the outer pressing mold and the inner pressing mold is arranged on a circular surface of the position which is shared by the outer pressing mold, the stop collar and the inner pressing mold. A rubber ring is uniformly and firmly embedded between the wheel hub and the belt wheel and the gap is filled with the rubber ring, the bonding performance and the damping performance are good, the production efficiency, the damping effect of the rubber ring and the damping effect of an automobile crankshaft are improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a fitting mold, in particular to a fitting mold of a rubber ring of a shock-absorbing pulley and an embedding method thereof. Background technique [0002] The damping pulley is mostly used on the crankshaft of the car. Different damping pulleys, especially the molding method and manufacturing process of the rubber damping damping pulley, have different damping effects and service life on the torsional vibration of the crankshaft itself. At present, there are roughly two molding methods for rubber damping shock-absorbing pulleys. One is to bond the rubber blank with the hub and pulley of the pulley to form a shock-absorbing pulley through direct vulcanization. Each pulley must be vulcanized. It is time-consuming, which has the problems of large vulcanization workload and low production efficiency; the other is to directly press the rubber ring between the hub of the pulley and the p...
