Problems solved by technology

[0002] The automotive PU headrest foaming mold usually includes an upper mold, a lower mold and a mold core. The mold core is connected to the upper mold. When the mold is opened, the product goes to the upper mold together with the mold core. The cylinder pushes the mold core and the product, and then the operator removes the product. This structure has the disadvantages of difficulty in taking the product and occupying a large space inside the mold. There are problems such as stroke shortage and asynchronous turning, so we need to design a foaming mold that ensures that the connecting rod pushes the mold core to turn over synchronously, so as to solve the above technical problems

Abstract

The invention relates to the technical field of foaming molds, and particularly discloses a foaming mold of a PU headrest mold core connecting rod turnover mechanism. The foaming mold comprises an upper mold, a lower mold, a mold core and the connecting rod turnover mechanism. The upper mold is connected with the lower mold. The mold core is arranged between the upper mold and the lower mold. Theconnecting rod turnover mechanism is arranged in the middle of the mold core and comprises a straight connecting rod, a bent connecting rod and a flat air cylinder. One end of the straight connectingrod is fixed to the center of the mold core through a first fixing seat, and the other end of the straight connecting rod is connected with the bent connecting rod. The bent connecting rod is connected with the flat air cylinder, and the flat air cylinder is fixed to the lower mold. The foaming mold is compact in structure, reasonable in layout and convenient to operate; operators can take products and clean the mold core conveniently; the connecting rod turnover mechanism is arranged in the center of the mold core, the mold core is stressed evenly and turned over synchronously; the problem that the drive stroke of the air cylinder is insufficient is avoided; and the air cylinder is arranged at the bottom of the lower mold, use space is reduced, and the problem that space in the mold is insufficient is effectively avoided.
