Problems solved by technology

Due to the special structure of the bayonet itself, the processing accuracy and symmetry are high, and the processing of this bayonet needs to be bent twice, which not only has poor symmetry, unstable dimensions, but also low production efficiency.

Embodiment Construction

[0018] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the invention, such as the shape, structure, mutual position and connection relationship between each part, the role and working principle of each part, etc., will be further described. detailed instructions.

[0019] like figure 1 As shown, the one-time forming composite mold of the present invention is made up of upper mold base 1, punch 4, lower mold base 9, briquetting block 3, slide block 6, etc., and upper mold base 1 is composed of upper template 11 and upper mold fixing plate 12, the lower mold base 9 is composed of a lower mold fixing plate 91 and a lower template 92, the whole set of molds is axisymmetric along the central axis, the upper mold base 1 is fixed on the punch press, and the lower mold base 9 is fixed on the base. Two identical pressing blocks 3 are fixed on the bottom plane of the upper die fixing plate 12, and the pressing b...

Abstract

The invention discloses a once-forming compound die. The compound die comprises a punch, an upper die base, a lower die base corresponding to the upper die base, a lower die and the like. A sliding block is arranged in a mould, can slide left and right to be combined with the punch and the lower die so as to form a bayonet lock raw material, a slope on the sliding block is matched up with a slope on a pressing block to compact a mould body, so that the bayonet lock forming can be beneficially formed, and high reject ratio of the produced bayonet locks and low production efficiency caused by the past production of bayonet locks needed to be bent and formed twice can be changed; and the bayonet lock can be formed once by the compound die, and the produced bayonet lock is high in precision, good in degree of symmetry, and high in once-forming production efficiency.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular, the invention relates to a one-shot composite mould. Background technique [0002] The quick joint oil inlet nozzle and the oil pipe joint of the traditional hydraulic pipeline are respectively installed on the upper and lower ports at both ends of the valve body. The elasticity of the fingers of the collar is prone to fatigue and failure, and the installation of the oil pipe joint and the lower interface is not firm, resulting in oil leakage and other problems. Therefore, a quick connector is provided, so that the oil pipe connector is tightly combined with the lower interface of the valve body to prevent oil leakage. Chinese Utility Model Patent Specification 200920267772.6 discloses such a quick connector, which includes a connector detent. Due to the special structure of the bayonet itself, the requirements for processing accuracy and symmetry are high, and the process...
