Hot press with demolding function

Abstract

The invention belongs to the field of presses, and particularly discloses a hot press with the demolding function. The hot press comprises an upper pressing plate and a fixing plate; the two ends of the upper pressing plate are connected with a first supporting frame and a second supporting frame in a sliding mode respectively; a plurality of sliding blocks are arranged in the first supporting frame; heating plates are arranged on the sliding blocks and are connected through springs; a motor is arranged above the upper pressing plate and is fixedly connected to a first rotating shaft, and the first rotating shaft is rotationally connected to a water tank; the water tank is rotationally connected to a second rotating shaft; a plurality of blades are arranged on the opposite ends of the first rotating shaft and the second rotating shaft; the second rotating shaft is fixedly connected to a lower pressing block; a hydraulic block is arranged at the bottom of the lower pressing block; a hollow cavity is formed in the hydraulic block; and the two ends of the hydraulic block are fixedly connected to the upper pressing plate through flexible connecting pieces. The invention provides the hot press with the demolding function. The hot press with the demolding function has the advantages that the upper pressing plate is stressed uniformly, and a plate is easy to demold and can be kept from being crushed.

Description

technical field [0001] The invention relates to the field of press equipment. Background technique [0002] There are many kinds of boards, which are widely used in daily life. In the processing of boards, compression molding technology is required to press the boards. In the existing compression molding technology, single-layer or multi-layer hot presses are generally used. Single-layer hot presses generally use belt conveying, and multi-layer hot presses mostly use loading and unloading plate machines to convey; When the hot press is processing plywood and blockboard, it is easy to appear the phenomenon that the center is shifted due to uneven force on the upper and lower pressing plates, which also makes the upper and lower pressing plates distorted and deformed, resulting in damage to the slab, which seriously affects the quality of the product and brings great harm to the enterprise. caused serious economic losses.

AI Technical Summary

Problems solved by technology

But this invention has the following problems: 1. The contact area between the expansion rod and the upper pressing plate is too small. When the expansion rod transmits the lower pressure to the upper pressing plate, the force of the position where the expansion rod contacts the upper pressing plate is the largest, while other positions of the upper pressing plate are affected. The force is small, resulting in uneven force on the upper platen, which affects the pressing quality of the plate; 2. When the plate is pressed through the upper and lower platens at the same time, the pressure on the uppermost and bottom layers of the plate is the largest, resulting in the plate being easily crushed
