Problems solved by technology

[0002] The existing overall prefabricated mold structure design is complex and has great limitations
Three-dimensional products can only be formed by vibrating on a vibrating table due to factors such as cross-section and steel bars, and its performance is only suitable for vibrating plates or other components with relatively short and simple cross-sections to exert pressure on the upper surface. For complex three-dimensional products, vibration The density is poor, and the air bubbles on the surface cannot be eliminated

Embodiment 1

[0032] like Figure 1~3 Embodiment 1 of the present invention is shown: a cement prefabricated part direct extrusion vibration method integral forming mold, including an inner mold 1 and an outer mold 2, both of which are barrel-shaped structures; A cavity 3 for pouring is formed between them. The outer mold is spliced ​​by the two-petal outer mold and the outer bottom film with the joints of the leak-proof slurry and locked by bolt connection. The outer mold and the outer bottom mold have Anti-extrusion ability, located in the inner mold 1, has a tensioning mechanism that pushes the inner mold 1 to expand outward and squeeze downward. When the inner cylinder mold is squeezed, it expands horizontally and also squeezes the inner bottom mold vertically downward. The inner mold 1 includes an inner bottom mold 4 located at the bottom and an inner cylinder mold 5 surrounded by a side wall. The inner cylinder mold 6 is surrounded by steel plates, and the two joints at the joints of ...

Embodiment 2

[0049] like Figure 4 Showing Embodiment 2 of the present invention: the main difference between this embodiment and Embodiment 1 is that the opening and closing mechanism is different. In this embodiment, the bottom of the outer mold is provided with a base, the middle part of the outer mold is straight, and the upper part of the outer mold is Trumpet-shaped structure, the bottom, middle and upper parts of the outer mold are connected by bolts. The inner mold includes an inner top mold 27 located in the upper horn-shaped structure of the outer mold. The inner cylinder mold is located on the outer mold. Inside the straight cylinder in the middle of the mold, a cavity for pouring and tamping concrete is formed between the outer mold and the inner mold, and feed inlets 26 are set on the base, the top of the inner cylinder mold, and around the inner cylinder mold. The iron plate is rolled into a seam overlapped by 5cm, and passes through the inner top mold and the base up and dow...

Abstract

The invention relates to a cement prefabricated part direct-extrusion vibration method integral forming mold and a machining method thereof. The mold comprises an inner mold body and an outer mold body. A cavity used for pouring is formed between the inner mold body and the outer mold body. An opening and closing mechanism for pushing the inner mold body to expand outwards and extrude downwards is located in the inner mold body. The inner mold body comprises an inner bottom mold located at the bottom and an inner barrel mold forming a side wall in a defining manner. The inner barrel mold is defined by steel plates. Two connectors at steel plate seams are overlapped and in lap joint together and can slide relatively. The bottom of the inner barrel mold is movably connected with the inner bottom mold. A feeding device and a vibration deice located at the bottom of the inner mold body and the bottom of the outer mold body are further included. According to the cement prefabricated part direct-extrusion vibration method integral forming mold and the machining method thereof, air and redundant water in products are exhausted through extrusion vibration, the strength and density of product concrete are improved, a supernormal dense effect is obtained, and product anti-permeability and structural performance rigidity are improved. Due to the fact that absolute stability of not allowing concrete to have moving space exists in extrusion force, cracks generated by uneven settling do not exist.

Description

technical field [0001] The invention relates to a cement prefabricated part direct extrusion vibration method integral molding die and a processing method thereof. Background technique [0002] The existing overall prefabricated mold structure is complex in design and has relatively large limitations. Three-dimensional products can only be formed by vibrating on a vibrating table due to factors such as cross-section and steel bars, and its performance is only suitable for vibrating plates or other components with relatively short and simple cross-sections to exert pressure on the upper surface. For complex three-dimensional products, vibration The density is poor, and the air bubbles on the surface cannot be eliminated. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a cement prefabricated part direct extrusion vibration integral forming mold and its processing method, improve the compactness, strength and density of ...
