Example Embodiment

[0017] Example 1

[0018] A bakelite pouring mold, comprising a pouring system 4, a runner 2 connected with the outlet of the pouring system 4, and a cavity 1 connected with the outlet of the runner 2, the runner 2 is arranged in the heat insulating material 3, and the pouring system 4 is arranged There is a first heating device, and a second heating device is arranged on the cavity.

[0019] The present invention uses heat insulation material 3 to make the runner 2 of the mold. The temperature of the runner 2 is controlled at 75-85°C through an independent first heating device, and the temperature in the cavity 1 is controlled at 160 through an independent second heating device. -180℃, due to the heat insulation material, it can prevent the high temperature of the cavity 1 from solidifying the material in the runner 2 through heat conduction, so that the material in the runner 2 is always at the fluidized state temperature, and the material in the runner 2 can Recycling does not ...

Example Embodiment

[0020] Example 2

[0021] This embodiment is a further optimization on the basis of Embodiment 1. A mechanical valve 5 is provided between the outlet of the flow channel 2 and the cavity 1. Opening during pouring and closing after pouring can further reduce the heat conduction at the interface and prevent the phenolic resin in the runner 2 from curing.

Example Embodiment

[0022] Example 3

[0023] This embodiment is a further optimization on the basis of Embodiment 1 or Embodiment 2. The first heating device is a heating coil 5, and the heating coil 5 is wound on the pouring system 4. The temperature of the phenolic resin in the runner 2 is controlled at 75-85°C by the heating coil 5, which can flow without curing.

Abstract

The invention discloses a bakelite poured mould. The bakelite cast mould comprises a pouring system, runners connected to outlets of the pouring system, and cavities connected to outlets of the runners. The runners are arranged in a thermal insulation material, a first heating device arranged on the pouring system, and a second heating device is arranged on the cavities. By using the thermal insulation material to manufacture the runners of a mould, the temperature of the runners is controlled at 75-85 DEG C through the independent first heating device, and the temperature of a product forming region is controlled at 160-180 DEG C through the independent second heating device. As a result of action of the thermal insulation material, the material in the runners can be prevented from being cured due to high temperature of the product forming region, so that the material in the runners is in a fluidized state temperature all the way, and the material in the runners can be recycled without affecting injection filling.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a bakelite casting mold. Background technique [0002] The phenolic plastic valley is called bakelite powder. The fluidization temperature of phenolic plastic is between 75°C-85°C and the molding temperature is 160°C-180°C. The production process of the material is simple and the cost is low. It has a history of more than 100 years. [0003] Phenolic plastics are flame-retardant, high-temperature resistant, corrosion-resistant, water-resistant, good insulation, strong acid resistance, high mildew resistance, high frequency of use, and the product does not deform after molding. Dimensionally stable. Widely used in industry, construction, military, aviation, daily necessities and other fields. [0004] When using mold casting, phenolic plastic is injected from the runner, then flows into the product forming area, and solidifies in the product forming area. Due to the...
