Forming machine with cooling mechanism

Abstract

The invention discloses a forming machine with a cooling mechanism, comprising a cooling mechanism which comprises a controller, an electromagnetic valve, a pneumatic angle seat valve (1), a pneumatic angle seat valve (2), a pneumatic angle seat valve (3) and a cooling pipe, wherein the controller controls the electromagnetic valve, and the pneumatic angle seat valve (1) and the pneumatic angle seat valve (2) can be selectively opened by utilizing the compressed air of the electromagnetic valve; and cooling water penetrates into and cools the inner part of a mould through the cooling pipe so that polypropylene raw materials are bonded and formed. When the pneumatic angle seat valve (1) and the pneumatic angle seat valve (2) are closed, the pneumatic angle seat valve (3) is opened, and the cooling water in the cooling pipe flows back to a water tank so that the pressure on a water pump is reduced. The forming machine controls the electromagnetic valve by utilizing the controller, when the pneumatic angle seat valve (1) and the pneumatic angle seat valve (2) are closed, the pneumatic angle seat valve (3) is opened, the cooling water in the cooling pipe flows back to the water tank so that the pressure on a water pump is reduced, and therefore, the water pump is difficult to damage.

Description

technical field [0001] The invention relates to a molding machine, in particular to a molding machine with a cooling mechanism, and belongs to the technical field of molding machines. Background technique [0002] Molding machine is one of the commonly used molding machines in industry. The existing molding machine includes a cooling mechanism, and the cooling mechanism includes a solenoid valve, a pneumatic angle seat valve, and a cooling pipe; the solenoid valve is controlled, and the pneumatic angle seat valve is opened by using the compressed air of the solenoid valve. The cooling water penetrates and cools the mold through the cooling pipe, so that the polypropylene raw materials are bonded and formed. In this cooling mechanism, when the angle seat valve is closed, the cooling water remains in the water pump, which exerts a large pressure on the water pump and easily damages the water pump. Contents of the invention [0003] The object of the present invention is to...
