Fuel tank die

Abstract

A fuel tank die comprises a die body (1) arranged on a die base, and a cavity (2) formed in the die body (1). A needle blowing mechanism (3) is located at the upper end of the die body (1). The width of the upper end of the cavity (2) is smaller than that of the lower end of the cavity (2). An arc-shaped rail (4) and a linear guide rail (5) are arranged at the upper end of the die body (1), the arc-shaped rail (4) is connected with the linear guide rail (5) through an L-shaped support (6), and an arc-shaped through hole (9) is formed in the support (6) and extends along the arc-shaped rail (4). The needle blowing mechanism (3) is hinged to a piston rod of a first cylinder (8). Compared with the prior art, the fuel tank die has the advantages that material consumption is low, water-cooling solidification of products is facilitated, product cost can be reduced greatly, and quality stability is high.

Description

technical field [0001] The invention relates to an oil tank mold. Background technique [0002] At present, in order to avoid various auxiliary mechanisms and blanking mechanisms at the upper end of the mold, the fuel tank mold sets the blowing needle mechanism on the mold body corresponding to the lower part of the mold cavity, and the position of the blowing needle corresponding to the mold cavity is the position of the fuel tank after molding. Therefore, the relatively small end of the fuel tank body is located at the bottom, while the relatively large end of the tank body is located at the top; It is easy to go down, so that the wall thickness of the lower part of the fuel tank body is relatively thick, and the raw materials are relatively required, which increases the cost of the fuel tank; and the uneven wall thickness will make the fuel tank in water-cooled shape after forming. Uneven shrinkage, the shape of the fuel tank body is easy to deform, and the fuel tank bod...

[0002] At present, in order to avoid various auxiliary mechanisms and blanking mechanisms at the upper end of the mold, the fuel tank mold sets the blowing needle mechanism on the mold body corresponding to the lower part of the mold cavity, and the position of the blowing needle corresponding to the mold cavity is the position of the fuel tank after molding. Therefore, the relatively small end of the fuel tank body is located at the bottom, while the relatively large end of the tank body is located at the top; It is easy to go down, so that the wall thickness of the lower part of the fuel tank body is relatively thick, and the raw materials are relatively required, which increases the cost of the fuel tank; and the uneven wall thickness will make the fuel tank in water-cooled shape after forming. Uneven shrinkage, the shape of the fuel tank body is easy to deform, and the fuel tank body is also easy to deviate in a large range, resulting in deformation of the fuel tank body at the clamping position, resulting in a low rate of finished products, which eventually leads to a substantial increase in the cost of the finished product. The slight deformation of the fuel tank at the clamping position may easily lead to leakage during actual use, and the quality stability is poor
