Thermosetting plastic ultrasonic molding forming mold-closing device

Abstract

The invention discloses a thermosetting plastic ultrasonic molding forming mold-closing device. The thermosetting plastic ultrasonic molding forming mold-closing device mainly comprises a movable moldplate, a fixed mold plate, a mold set, injection molding accessories, a ultrasonic generator, a connecting cable, transducers, an amplification ejection rod, a sealing assembly and the like, the multiple transducers are distributed on an ejection plate in a central symmetry mode and connected with the ejection plate through threaded connecting pieces, the amplification ejection rod penetrates through the reserved position of the movable mold and participates in constituting of a manufacturing product mold cavity closed face, a spring pressing block in the sealing assembly in the movable moldplate is tightly attached to the amplification ejection rod under the effect of spring elastic force, and the sealing effect is achieved. According to the thermosetting plastic ultrasonic molding forming mold-closing device, the structural design of the amplification ejection rod is put forward, a traditional amplification rod and an injection molding machine ejection rod are combined together, aultrasonic system is introduced into an ejection mechanism of a thermosetting plastic injection molding machine, a curing mode of internal heating of a traditional thermosetting plastic injection molding machine mold is abandoned and changed into ultrasonic heating, design and manufacturing of an overall mechanical mold are effectively simplified, energy sources are saved, and the production efficiency and the manufacturing product quality are improved.

Description

technical field [0001] The invention relates to a mold clamping device with an ultrasonic heating device for a thermosetting plastic injection molding machine, which belongs to the field of polymer material molding machinery. Background technique [0002] With the increasing number and application of plastic products, thermosetting plastics have gained new development, and the injection molding process of thermosetting plastics has become a high-efficiency molding process characterized by high speed, automation and large-scale. [0003] Due to the special properties of thermosetting plastics, their molding process is significantly different from that of thermoplastics. Among the three stages of injection molding of thermosetting plastics, the curing stage is related to the molding quality of the product and is a direct reflection of whether the injection molding process is good or not. [0004] Traditional thermosetting plastic injection molding machines need to heat the mol...
