[CN 201910147188.5] Hydraulic press with pressurization


[CN 201910147188.5] Title of a hydraulic press with pressurization: Application number of a hydraulic press with pressurization: CN 201910147188.5 Applicant: Henan University of Science and Technology Application Date: 2019-2-27 Patent Type: Application for Invention The present invention relates to a hydraulic press with pressurization. The hydraulic press includes a frame, a hydraulic cylinder is provided on the frame, a mold clamping and pressing mechanism is connected to the piston rod of the hydraulic cylinder, and the mold clamping and pressing mechanism includes a connector and a holder, A connecting rod mechanism is arranged between the connector and the holder. The connecting rod mechanism includes a first toggle rod hinged with the holder and a connecting rod hinged with the connector. The connecting rod and the first toggle rod are hinged with each other. It also includes a swing limit structure. The first toggle rod is provided with a hinged fit structure at or near the hinged position of the connecting rod, the free end of the second toggle rod is provided with a clamping structure. The clamping structure is connected with the hinged fitting structure when the piston rod is down and clamped to form a hinged relationship, so that the linkage mechanism and the second toggle rod together form a toggle linkage mechanism. The clamping structure is relatively separated from the hinged fitting structure when the piston rod is up, so as to increase the operating space of the forming process.
