Problems solved by technology

[0002] The gear box parts are large in size, complex in structure and shape, high in technical requirements, and very difficult to produce. The existing gear box die-casting molds have problems such as unsmooth metal liquid flushing and insufficient pressure transmission, which are prone to shrinkage, porosity, Defects such as dimensional deviation, so casting quality is not high

Embodiment Construction

[0009] A hydraulic loose clamping roll bending die, which is composed of a lower die 1, an upper die 2, a die clamping cylinder 3, a straight line section 4, an auxiliary push die 6 and a clamping block, the lever of the die clamping cylinder 3 is fixed to the lower die 1 The upper mold 2 is connected to the cylinder, and the cylinder moves up and down relative to the cylinder rod to drive the upper mold and the lower mold to be separated. When loading and unloading, it is convenient for the workpiece 5 to be close to the mold or withdraw from the mold, thereby realizing automatic servo feeding. The upper mold 2 and the lower mold 1 are made of carbon steel by turning, milling, drilling, and heat treatment; the straight line section 4, auxiliary push mold 6, and clamping block 7 are made of carbon steel by milling, drilling, or heat treatment.

[0010] In the present invention, hydraulic unclamping device is adopted in addition to workpiece unclamping, auxiliary pushing (longit...

Abstract

A hydraulic loosening and clamping roll-bending mold is composed of a lower mold (1), an upper mold (2), a mold clamping oil cylinder (3), a linear segment (4), an auxiliary pushing mold (6) and a clamping block; a cylinder rod of the mold clamping oil cylinder (3) is fixedly connected with the lower mold (1), the upper mold (2) is connected with a cylinder barrel, the cylinder barrel vertically moves relative to the cylinder rod so as to drive the upper mold and the lower mold to be disengaged, during loading and unloading, a workpiece (5) can be conveniently close to or retreat from the mold, and automatic servo feeding can be achieved. Compared with a traditional mold, except for transverse loosening and clamping, the mold is specially designed to be of an upper and lower two-body structure, a vertical loosening and clamping mechanism is additionally arranged, and automatic feeding can be conveniently achieved.

Description

technical field [0001] The invention relates to the die-casting of gear box parts, in particular to a hydraulic loose clamp roll bending die. Background technique [0002] The gear box parts are large in size, complex in structure and shape, high in technical requirements, and very difficult to produce. The existing gear box die-casting molds have problems such as unsmooth metal liquid flushing and insufficient pressure transmission, which are prone to shrinkage, porosity, Defects such as dimensional deviation, so the casting quality is not high. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a hydraulic loose clamp roll bending die with high product casting quality. The produced gear box has good surface quality, no defects in appearance, high production efficiency, and fully meets the design requirements. [0004] The technical solution of the present invention is realized in the following manner:...
