Embodiment 1

[0024] Example 1, such as figure 1 As shown, an internal expansion block forming device includes a mold 1 having at least one closed space and at least one mold core 2 that can expand to the surroundings in the middle of the closed space, and the mold core and the mold An annular material space is formed between them, and the mold core compacts the material 3 in the annular material space under the action of expansion force; wherein, the mold includes a mold frame 11, an upper mold 12 and a lower mold 13, and the mold core The mold frame is hollow cylindrical with upper and lower openings, the lower mold can move up and down and close the lower opening of the mold frame when forming blocks or press into the mold frame to a certain depth, the upper mold can move up and down and When forming blocks, the upper opening of the mold frame is closed or pressed into the mold frame to a certain depth; the lower mold is formed with an ejector plate 131 that can move up and down, and the...

Embodiment 2

[0030] Embodiment 2, this embodiment 2 has most of the technical features of embodiment 1, the difference is that the mold core of the device is a special ceramic with electricity expansion characteristics, and by electrifying the special ceramic, it will expand to the surrounding Material compaction in the annular material space.

[0031] In this way, when working, the upper mold goes up to the highest position, the lower mold is at the feeding position (closes the lower opening of the mold frame), and a specified amount of material is added to the mold frame, and then the upper mold goes down and pre-presses into the mold frame to a certain depth. , the lower die is pre-pressed into the mold frame to a certain height at the same time or step by step. After the height of the hollow block (brick) is determined, the upper and lower dies are fixed; The material in the space is pressed against the surrounding mold frame. When the mold core expands to the predetermined pressure, t...

Abstract

The invention discloses an internal expansion type block molding device and method. The molding device comprises a mould provided with at least one confined space, and at least one mould core which is arranged at the middle part of the confined space and can expand around; an annular material space is formed between the mould core and the mould, and materials in the annular material space are compacted through the mould core under the effect of expansion power. In the invention, the height of a hollow block (brick) is not limited, and the molded product density is even; the strength is improved to the theoretical standard of material formula, and the power consumption of the molding process is lower.

Description

technical field [0001] The invention relates to a device for pressing hollow building blocks (bricks) for construction, in particular to an internally expanding block forming device and method. Background technique [0002] The production of building wall materials such as bricks and blocks by shock pressure or static pressure pressing technology is the basic national policy for my country to implement the prohibition of sticking and solidification, and to promote new building materials to achieve energy saving, consumption reduction, and protection of cultivated land. However, no matter the existing shock pressure or static pressure forming technology, there are technical defects in product quality, production capacity, cost control, equipment reliability, etc., so that the work of banning sticking and banning in our country is in a state of being unpopular. situation. Contents of the invention [0003] In order to solve the above technical problems, for hollow blocks (h...
