Embodiment Construction

[0009] exist figure 1 Among them, the epoxy resin pressure gel molding machine includes a movable frame, which is composed of a fixed template 2, a guide rod 3, a movable template 10, a cylinder 1 and an ejection mechanism, and the piston rod on the cylinder moves through the The fixed template 2 is connected with the movable template 10, and four guide rods 3 are arranged between the fixed template and the movable template. The movable template is equipped with a heating plate 4, and the heating temperature is 150-200°C. On the two heating plates, one end of the ejector pin passes through the heating plate and the mold, and the other end is connected to the ejector mechanism. The ejector mechanism includes a top plate and an ejector pin (not shown in the figure), and the mold is closed to form a voltage The shape contour space of the transformer body 9 is provided with a glue injection hole 5 on the mold, and the glue injection hole is connected with the vacuum mixing tank 6 ...

Abstract

The invention discloses an epoxy resin pressure gel forming machine which comprises a movable rack, a heating plate (4) assembled on the rack and an open-close type mould (8) assembled on the heating plate, wherein an ejecting mechanism capable of withdrawing a voltage transformer blank body (9) in the mould is arranged on the rack, the mould is connected with a vacuum stirring tank (6) through a gel injecting hole (5) and a gel injecting pipe (7), and gel is injected into the mould by the vacuum stirring tank when the vacuum pressure is 8kg/cm<3> (about 0.8MPa). Compared with an existing epoxy resin pressure gel forming device, the epoxy resin pressure gel forming machine disclosed by the invention has the advantages that the machine is compact in structure, small in floor space, and convenient to operate; the machine is quick to heat, short in heating time, and short in curing time, so that the manufacture efficiency can be improved; a set of mould can be recycled, so that the manufacture cost of the mould can be saved, and the cost can be reduced; and the gel is convenient to inject, and the mould is convenient to open, so that the machine is small in labor intensity, and environment-friendly in working environment.

Description

technical field [0001] The invention relates to a pressure molding machine, in particular to an epoxy resin pressure gel molding machine. Background technique [0002] A voltage transformer is generally composed of a coil, an iron core and an insulating layer, and the insulating layer (shell) is mostly cast and cured with epoxy resin. When manufacturing, first use epoxy resin to fully stir in a vacuum tank to form epoxy resin glue, place the mold with coils, etc. in the heated cylinder, and then inject the epoxy resin gel into the mold, and the mold is heated After the epoxy resin gel is solidified, the voltage transformer can be made by removing it from the tank and cooling it and then opening the mold. However, this manufacturing method has the following problems: firstly, the molds accumulated in the tank body take a long time to heat up, resulting in long gel curing time and low manufacturing efficiency; secondly, the injection and mold opening operations are inconvenie...
