Silencer forming device

Abstract

The invention relates to the technical field of silencer production accessory devices, in particular to a silencer forming device. The device is simple in structure and facilitates disassembly and assembly of a lower die, and meanwhile, the angle of an upper die can be adjusted, so that the upper die is convenient to maintain and repair, and the use limitation is reduced. The device comprises the upper die and the lower die, the upper die and the lower die are the same in structure and are symmetrically arranged relative to the horizontal line where a die assembly line is located; The device further comprises a workbench, two sets of fan-shaped plates, two sets of reset springs, two sets of connecting rods, a baffle, a base, a threaded rod and a limiting rod, a sliding chute matched with the lower die in shape is formed in the top of the base, grooves are formed in the front side and the rear side of the left side wall in the sliding chute, through holes communicating with the left side wall of the base are formed in the center areas of the left side walls in the grooves, locking grooves are formed in the front side and the rear side of the left side wall of the lower die, and the two ends of each set of fan-shaped plates are located in one set of locking grooves and one set of grooves correspondingly.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for producing mufflers, in particular to a molding device for mufflers. Background technique [0002] As we all know, the muffler is a device that prevents sound transmission and allows airflow to pass through. It is an important measure to eliminate aerodynamic noise. The muffler is installed in power equipment with loud exhaust noise such as blowers, air compressors, and generators A noise reduction device on the air flow channel or in the intake and exhaust system, the existing muffler is cast. [0003] The existing muffler molding device includes an upper mold and a lower mold. The upper mold and the lower mold have the same structure and are installed symmetrically with respect to the horizontal line where the parting line is located; when the existing muffler molding device is used, the upper mold is controlled by a hydraulic cylinder.

[0003] The existing muffler molding device includes an upper mold and a lower mold. The upper mold and the lower mold have the same structure and are installed symmetrically with respect to the horizontal line where the parting line is located; when the existing muffler molding device is used, the upper mold is controlled by a hydraulic cylinder. Lifting and lowering, during normal use, place the embryonic tube in the lower mold, the upper mold presses down, the left punch and the right punch (not shown) are squeezed from left to right to the center, so that the embryonic tube is in a sealed state , the bulging medium is injected between the upper die and the lower die, the left punch and the right punch are forced to the center at the same time, and the blank tube is completely fitted under the high extrusion force and high water pressure of the left punch and the right punch The forming cavity of the mold forms the muffler; in the use of the existing muffler molding device, it is found that the lower mold is inconvenient to disassemble and install. At the same time, the surface of the upper mold and the lower mold needs to be cleaned Maintenance and repair, it is obvious that the location of the upper mold is inconvenient
