Turnover hydraulic mould frame

Abstract

The invention discloses a turnover hydraulic mould frame which comprises a mould frame base, a mould clamping mechanism, an upper mould plate and a lower mould plate, wherein, the upper mould plate and the lower mould plate can be switched between an overlapping state and a separating state. The turnover hydraulic mould frame is characterized in that the upper mould plate and the lower mould plate of the hydraulic mould frame are arranged in a relatively turnover manner, wherein, the upper mould plate is connected with a flange-type hole output double rack-shaped hydraulic turnover cylinder; the turnover angle is greater than 90 degrees; the lower mould plate is connected with a rod type fluid cylinder to achieve turnover; and the mould clamping mechanism is locked or unlocked when the two mould plates are overlapped. The turnover hydraulic mould frame is applied, so that the upper mould plate of the mould frame drives an upper mould of a mould to open a greater angle, the angle can be directly set as 180 degrees commonly, the space for a worker to take out a workpiece can be enlarged further, and the practical operation can be facilitated.

Description

technical field [0001] The invention relates to a flip-type hydraulic formwork for foam production, in particular to a formwork design for making car carpets. Background technique [0002] The automobile carpet polyurethane foaming line is produced by a polyurethane high-pressure foaming machine and a hydraulic formwork (mould is installed in the formwork). The mold opening and closing actions of the hydraulic mold base in the production process are controlled by an oil cylinder. This oil cylinder generally uses a tie rod cylinder or an engineering cylinder, and its disadvantages are obviously limited in stroke and limited inversion angle (generally less than 90°). Due to the large size of large-scale products, the turning angle of the hydraulic mold base is too small, which is not conducive to actual operation, and is not conducive to the production of large-scale products such as automobile carpets. Contents of the invention [0003] In view of the above-mentioned defec...

Problems solved by technology

The mold opening and closing actions of the hydraulic mold base in the production process are controlled by an oil cylinder. This oil cylinder generally uses a tie rod cylinder or an engineering cylinder, and its disadvantages are obviously limited in stroke and limited inversion angle (generally less than 90°).

Due to the large size of large products, the turning angle of the hydraulic mold base is too small, which is not conducive to the actual operation, and is not conducive to the production of large products such as car carpets.
