A multi-layer mold press

Abstract

The invention discloses a multi-layer mold pressing machine. The multi-layer mold pressing machine comprises an upper heating plate, a plurality of middle heating plates and a lower heating plate, wherein the upper heating plate, the middle heating plates and the lower heating plate are vertically distributed. The multi-layer mold pressing machine is characterized in that mold pushing plates are arranged on the upper surfaces of the middle heating plates and the upper surface of the lower heating plate and connected with mold pushing air cylinders; inner guide plates are arranged on the left sides and the right sides of the mold pushing plates; a middle mold releasing mechanism is arranged in front of the heating plates and comprises a frame body, outer guide plates, mold releasing frames and a mold releasing oil cylinder; guide columns are arranged between the upper end and the lower end of the frame body, the outer guide plates are fixedly arranged on the guide columns, and outer guide grooves of the outer guide plates are aligned at inner guide grooves of the inner guide plates in the mold releasing state in a front-and-back manner; and the mold releasing frames are arranged above the outer guide plates in a vertically-movable manner, vertical movement of the mold releasing frames is pushed by the mold releasing oil cylinder, lateral grooves for supporting middle molds are formed in the mold releasing frames, and the groove width of the lateral grooves in the vertical direction is larger than the height of the lateral sides of the middle molds. The multi-layer mold pressing machine is high in production efficiency, the labor intensity of workers is reduced, the operation safety is improved, and the function of synchronous air discharging of multiple layers of molds can be achieved.

Description

technical field [0001] The invention relates to a hydraulic press equipment capable of simultaneously performing multi-layer mold pressing and forming. Background technique [0002] A hydraulic press is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and forming processes. Most of the hydraulic presses use a single-layer mold to press and form the product, but there are also two-layer or three-layer molds that simultaneously press and form the product. The deficiencies in the prior art hydraulic press mainly include: 1. The ejection plate, the middle mold, the product removal, and the raw materials are generally carried out inside the press, and the operation safety is relatively poor. If all the above actions are carried out outside the press, the entire action The structure is complex, the operation is inconvenient, the production efficiency is low, and the labor intensity of the wor...

Problems solved by technology

The deficiencies in the prior art hydraulic press mainly include: 1. The ejection plate, the middle mold, the product removal, and the raw materials are generally carried out inside the press, and the operation safety is relatively poor. If all the above actions are carried out outside the press, the entire action The structure is complex, the operation is inconvenient, the production efficiency is low, and the labor intensity of the workers is high; 2. During the process of pressing the formed product, the press often needs to perform multiple mold exhausts in the closed mold state. At this time, the mold is required to be slightly opened to exhaust The distance allows the gas in the mold to be exhausted. If the press uses a multi-layer mold, then the multi-layer mold must be opened layer by layer for exhaust. The entire exhaust process takes a long time and the production efficiency is low.
