Problems solved by technology
In actual use, the steam inlet pipe of this steam molding machine only passes through steam, and the water inlet pipe only passes through cooling water, so the utilization rate of the pipeline is low. In order to meet the heating and cooling process conditions, the cost of the pipeline is relatively high
In addition, when the steam compression molding machine is pressing some large molds, because only the steam box on the top is pierced with steam pipes, the temperature distribution inside the entire mold cavity is uneven, which affects the molding quality of the foundry plastic mold.

The invention discloses an improved type vapor press molding machine which can improve the utilization rate of a pipeline so as to reduce the cost of the pipeline. The improved type vapor press molding machine comprises a base which is provided with at least three stand columns, wherein the stand columns are parallel to one another; each stand column is provided with a lifting seat; each stand column is also movably provided with a press molding seat between the base and each lifting seat; a lifting device is arranged between each press molding seat and each lifting seat; each press molding seat is provided with a steam box on the side opposite to the base; at least one steam and water inlet pipe which is communicated with each steam box is arranged on each press molding seat in a penetrating way; each steam and water inlet pipe is connected with a steam pipe by a first steam inlet valve, and is connected with a cold water pipe by a water inlet valve; the base is provided with a pressure reducing hole and a drainage hole. The improved type vapor press molding machine is mainly used for manufacturing various sand-casting plastic moulds.
Description
technical field [0001] The present invention relates to a compression molding machine for making sand-turned plastic molds, in particular to a steam compression molding machine. Background technique [0002] The traditional sand foundry process uses a manual mold. The consistency of the manual mold is very poor, and the finished product obtained by casting the manual mold is light and heavy, and the quality of the finished product cannot be guaranteed. To this end, a steam compression molding machine came into being. The die base is provided with a lifting device between the die base and the lift base. The die base is provided with a steam box on the side opposite to the base. The die base is provided with two steam pipes and two steam pipes which communicate with the steam box. The water inlet pipe communicates with the steam pipe through the steam inlet valve, the water inlet pipe communicates with the cold water pipe through the water inlet valve, and the base is provid...
