Problems solved by technology

However, the above three extrusion casting devices and methods all provide static pressure. If the casting is thick, the extrusion effect will be greatly reduced. At the same time, for local extrusion, if the feeding path is blocked, the required static pressure will be reduced. Greatly improved, it needs a lot of extrusion force, the equipment structure and hydraulic system are very large, and it needs to consume a lot of energy

Embodiment 1

[0034] The vibration squeeze casting method with large vibration force and large amplitude described in this embodiment is as follows:

[0035] First, a vibrating rod is inserted into the casting mold, and the vibrating rod is applied with a vibration pressure of large vibration force and large amplitude by a vibration exciter (specifically, a large vibration force and large amplitude mechanical or electromagnetic vibration generator), and It can transmit the large vibration force and large amplitude vibration pressure applied to it to the formed metal material in the cavity of the casting mold, and provide a vibration pressure field for the formed metal material to directly act on the formed metal material itself; when When casting is required, the movable mold and the fixed mold in the casting mold are molded together to form a mold cavity, and then the required molded metal material is injected into the mold cavity, and finally by applying a large vibration to the vibrating ...

Embodiment 2

[0040]Such as figure 2 As shown, the difference from Embodiment 1 is that the mold opening and closing device of this embodiment includes a mold opening and closing hydraulic cylinder 201 for controlling mold opening and closing, a movable mold seat plate 202, and a guide column 203. The large vibration force is large The amplitude vibration device part includes movable guide rod 204, promotes pressing plate 205, vibrating rod 206, vibration push plate 207, push plate hydraulic cylinder 208, vibration motor 216, and described casting mold device part includes movable mold 209, fixed mold 210, Runner cut-off plate 211, liquid riser 212, container 213 for holding the metal material to be formed, and holding furnace 214, wherein the movable mold seat plate 202 is movably fitted on the guide column 203, and is controlled by the mold opening and closing hydraulic cylinder 201 Control the up and down movement; the movable mold 209 and the fixed mold 210 face up and down, the movabl...

Embodiment 3

[0043] Such as image 3 As shown, the difference from Embodiment 1 is that the mold opening and closing device part of this embodiment includes a mold opening and closing hydraulic cylinder for controlling mold opening and closing, and a movable mold seat plate 310. The vibration device with large vibration force and large amplitude includes Vibrating bar 301, vibrating push plate 302, vibrating motor 303, pressing plate 312 are arranged, and the casting mold device part can be turned over 90° as a whole, so that the fixed mold seat plate 307 is in contact with the ground, and it includes a movable mold 304, a fixed mold 305, Runner cut-off plate 306, fixed mold base plate 307, elastic gasket 308, wherein, the movable mold base plate 310 is controlled to move left and right by the mold opening and closing hydraulic cylinder, and the movable mold 304 and the fixed mold 305 are opposite to each other and can be combined A mold cavity 311 is formed, and the movable mold 304 is fi...

Abstract

The invention discloses a large vibration force large amplitude vibrating squeeze casting method and a casting device thereof. The large vibration force large amplitude vibrating squeeze casting method comprises extending a vibrating rod inside a casting mold and enabling a movable mold and a stationary mold of the casting mold to form into a mold cavity when casting is required to be performed; injecting formed metal materials into the mold cavity; applying large vibration force large amplitude vibration pressure to the vibrating rod to enable the squeezing force of the formed metal materials to be changed into dynamic squeezing force to enable vibratory pressing to be performed on the formed metal materials inside the mold cavity and accordingly forming into the vibrating pressure filed in the formed metal materials to enable vibratory compression to be performed on the formed metal materials inside the mold cavity and obtaining required high density shrinkage-cavity-shrinkage-defect-free casting products. The large vibration force large amplitude vibrating squeeze casting method has the advantages of having advantages of the existing vibrating device, meanwhile enabling the device tonnage to be reduced substantially, greatly reducing consumption and simplifying a control system and a hydraulic system substantially.

Description

technical field [0001] The invention relates to the technical field of casting methods and equipment, in particular to a large-vibration force, large-amplitude vibration extrusion casting method and a casting device thereof. Background technique [0002] Due to the comprehensive influence of various conditions during the filling and solidification process of castings, it is easy to produce some casting defects such as pores, shrinkage cavities, and shrinkage porosity. Traditionally, these defects can be eliminated by changing the pouring parameters and modifying the mold. With the continuous development of the casting industry, users have higher and higher requirements for the quality of casting products, the required product size is getting larger and the structure shape is becoming more and more complex, so it is becoming more and more difficult to control the product quality. In recent years, the development of the automobile industry has advanced by leaps and bounds, and...
