The present invention relates to a hot press forming machine, in particular to a hot press forming machine that uses a cover and a temperature control fluid to directly control the temperature of the mold to achieve rapid temperature rise and fall, shorten the process time, and save energy.

The traditional single-layer hot press molding machine is equipped with a temperature-controlled flow channel on the mold base, which can switch between hot and cold fluids to facilitate heating and molding of the mold and the shoe material in it and cooling and setting. However, repeated heating and cooling of the mold and mold base consume a lot of energy. At present, the industry has developed another double-layer thermoforming machine, which uses a single hydraulic cylinder to push the mold holders arranged in layers up and down, and the two-layer mold holders control heating and cooling separately to achieve the purpose of energy saving and environmental protection.

However, whether it is a conventional single-layer or double-layer thermoforming machine, the mold often needs to be replaced depending on the product being produced. In order to save the production cost of the mold, a hot plate or a cold plate is usually installed on the machine. , And then fix the mold on the hot plate or cold plate. When heating or cooling, the hot plate or cold plate is directly heated or cooled, and then the mold is indirectly heated or cooled by heat conduction. In this way, the heating or cooling of the hot plate or the cold plate itself consumes considerable energy when raising and lowering the temperature. Indirectly heating or cooling the mold through heat conduction will increase the time required for raising and lowering the temperature and cannot shorten the process time.

In order to solve the above-mentioned problems, the present invention discloses a hot press molding machine, which can use a driving part arranged above the machine table to drive the double-layer mold to open and close the molds separately, and to prevent the driving part from leaking or spraying due to the heating and cooling liquid , Causing the driving parts to rust easily and reduce the service life.

To achieve the above objective, an embodiment of the present invention provides a hot press forming machine, which includes: a base on which at least one first mold can be set; a cover with a hollow accommodating space and a cover The system is connected to at least one cover body driving device to drive the cover body toward or away from the base, wherein at least one second mold can be provided in the accommodation space, and the second mold is connected to At least one lifting drive device to drive the second mold toward or away from the first mold; at least one temperature-controlled fluid channel, the temperature-controlled fluid channel is connected to at least one temperature-controlled fluid source and the accommodating space between.

In an embodiment of the present invention, the temperature control fluid source may be at least one of steam, high temperature air, cooling water, or cooling air.

In an embodiment of the present invention, the cover is an open end relative to the base end.

In an embodiment of the present invention, the cover driving device may be at least one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

In an embodiment of the present invention, the lifting drive device is a power cylinder, the power cylinder has a drive shaft, and the end of the drive shaft is connected to the second mold.

In an embodiment of the present invention, the power cylinder may be at least one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

In an embodiment of the present invention, a fixing plate is provided at the end of the drive shaft, and the fixing plate can be used to fix the second mold.

In an embodiment of the present invention, the fixing plate is a grid plate with plural hollows.
