Description

Forming machine has vacuum cover structure capable of closing mould up and down

Technical Field

The utility model relates to a processing machinery's technical field especially indicates a make-up machine has the vacuum cover structure of compound die from top to bottom.

Background

Referring to fig. 1, a general molding machine 10 mainly includes a housing 11, a first mold base 12 and a second mold base 13, the first mold base 12 and the second mold base 13 are installed in the housing 11, a first mold 121 is installed on the first mold base 12, a second mold 131 is installed on the second mold base 13, and the first mold 121 and the second mold 131 are assembled for subsequent molding.

In the process of clamping and forming, after an operator places an unformed workpiece blank on the second mold 131, the forming machine 10 is started to move the first mold base 12 toward the second mold base 13 until the first mold 121 and the second mold 131 are clamped to each other, so that the workpiece located between the first mold 121 and the second mold 131 is machined into a specific shape.

It should be noted that, in general, when the first mold 121 and the second mold 131 are closed to mold, the material placed between the first mold 121 and the second mold 131 is shaped after temperature change or other physical changes, the pressing of the first mold 121 and the second mold 131 is to resist the pressure generated by the material shaping, and the pressing is tight, and in the pressing process, the force flow line formed by the closing pressure is transmitted from the second mold 131 through the first mold 121, so the strength of the

molds

131 and 121 must be extremely large; and air is generated during the material forming process (such as foaming forming), and if the air is not properly discharged between the first mold 121 and the second mold 131, a void appears on the finished product to become a defective product; when air is generated, the internal pressure in the two

molds

121 and 131 is increased greatly, the two

molds

121 and 131 resist the internal pressure, the strength and the thickness of the molds must be improved, and the weight of the molds must be increased greatly, so that the manufacturing cost of the molds is increased, the difficulty in transportation and the possibility of work injury during personnel transportation are increased, and the improvement is necessary; in order to solve the defect problem of the finished product, it is further proposed to provide a vacuum structure on the first mold 121 or the second mold 131 and connect a vacuum device (not shown in the known structure), when the first mold 121 and the second mold 131 are closed and molded, the vacuum device can extract air in the closed mold of the two

molds

121, 131 in cooperation with the vacuum structure, so as to reduce the problem of voids in the finished product, but the vacuum structure is easily blocked during the air extraction process, so that the vacuum device is damaged, and after the inner mold is evacuated after the two

molds

121, 131 are closed, the external atmospheric pressure still needs to be resisted, the structure still needs to maintain a certain strength, so the mold without the vacuum device is easily lost in terms of weight and cost.

However, the heavy mold is expensive in manufacturing cost, which increases the processing cost, and a large amount of heat energy must be consumed during heating to heat the heavy mold 121 and the heavy mold 131, so that the temperature inside the mold is easily dissipated outwards due to direct conduction, and the molding temperature cannot be maintained in an optimal state, and the heavy mold is difficult to transport, which greatly increases the difficulty in disassembling the first mold 121 and the second mold 131.

Accordingly, it is necessary to provide a technical solution to solve the problem that the mold clamping pressure is concentrated on the first mold 121 and the second mold 131, which results in heavy mold and high cost.
