Closed framework pressing mold

Abstract

The invention discloses a closed framework pressing mold, and particularly relates to the field of molds. The closed framework pressing mold comprises an upper locating mechanism, a lower locating mechanism and a pressing mechanism. The pressing mechanism is arranged between the upper locating mechanism and the lower locating mechanism. The upper locating mechanism comprises an upper mold plate and an upper male mold body. The upper male mold body is located below the upper mold plate and fixedly connected with the lower mold plate. The lower locating mechanism comprises a lower mold plate and a lower male mold body. The lower male mold body is arranged above the lower mold plate and fixedly connected with the lower mold plate. The pressing mechanism comprises a mold sleeve and a female mold body. The mold sleeve is connected to the outer surface of the female mold body in a sleeving manner. The female mold body is composed of multiple mold units. The female mold body is fixedly connected to the lower mold plate. The upper male mold body and the lower male mold body are identical in shape and opposite in position. The upper male body, the lower mold body and the multiple mold units define a concave forming cavity. According to the scheme, the closed framework pressing mold solves the problems that an existing plastic mold is complicated in structure, and operation expenses such as corresponding equipment maintenance expenses, electricity consumption and hydraulic energy consumption and labor cost are high.

Description

technical field [0001] The invention relates to the field of molds, in particular to a closed skeleton pressing mold. Background technique [0002] The compression molding mold is called the compression mold for short. The plastic raw material is directly added to the open mold cavity, and then the mold is closed, and the plastic becomes a fluid state under the action of heat and pressure and fills the cavity; then the plastic is hardened and shaped due to physical changes. This method is called compression molding. The mold used is called a compression molding mold. This kind of mold is mostly used for molding of thermosetting plastics, and also for thermoplastics. There is also an unheated cold forming press mold for forming PTFE blanks. [0003] In recent years, with the rapid development and general use of the plastics industry, the strength and precision of engineering plastics have been continuously improved, making the application range of plastic products also exp...
