[0023] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and a detailed implementation method and specific working process are given. However, the protection scope of the present invention is not limited to the following embodiment.

[0024] like Figure 1-4As shown, the vertical extrusion molding equipment for butter bricks described in the present invention is composed of a frame, a molding unit and a demoulding unit. The above-mentioned frame is composed of four columns 11 arranged along a rectangle and a top frame 12 connected to the columns 11. The molding unit is composed of a brick mold cavity 21, an upper pressure plate 22 and a lower pressure plate 23. Among them, the brick mold cavity 21 is a rectangular structure with an upper opening, which is located in the middle of the frame and welded to the column 11; the upper pressure plate 22 is connected to the top frame 12 through a hydraulic cylinder 24, and the cylinder body of the hydraulic cylinder 24 is installed on the connecting plate in the middle of the top frame 12, and the telescopic rod of the hydraulic cylinder 24 is connected to the center of the upper pressure plate 22; the lower pressure plate 23 is located in the brick mold cavity 21 and is adapted to the inner cavity of the brick mold cavity 21. The demoulding unit is composed of a guide rod 31, a connecting rod 32 and a pull rod 33. Among them, the guide rod 31 is connected to the lower pressing plate 23, and extends downward through the bottom plate of the brick mold cavity 21; the connecting rod 32 is connected to the end of the guide rod 31 and extends to both sides of the frame; the pull rod 33 is set at both ends of the connecting rod 32, and one end of each pull rod 33 is hingedly connected to the connecting rod 32, and the other end is provided with a connector for connecting to the upper pressing plate 33. Specifically, the guide rod 31, the connecting rod 32 and the pull rod 33 are arranged in the same plane, and are all located in the median vertical plane of the upper pressing plate 22 and the lower pressing plate 23. Among them, the guide rod 31 is two vertical rods, the connecting rod 32 is a horizontal rod, the pull rod 33 is set on the outside of the brick mold cavity 21, and the connector at its top is a card plate 34 that is clamped to the upper surface of the upper pressing plate 22. In order to ensure that the molded butter brick M is smoothly demolded, the length of the above-mentioned connecting rod 32 is at least as long as the inner cavity height of the brick mold cavity 21.

[0025] During operation, first, the pull rod 33 is toggled to disengage the card plate 34 from the upper pressing plate 22, and the connection between the pull rod 33 and the upper pressing plate 22 is disconnected; at this time, the lower pressing plate 23, the guide rod 31, and the connecting rod 32 fall under the action of gravity until the lower pressing plate 23 falls on the bottom of the brick mold cavity 21; thereafter, the stirred butter and talcum powder mixture is poured into the brick mold cavity 21, and the hydraulic cylinder 24 is started to make the upper pressing plate 22 extrude the material in the brick mold cavity 21 back and forth; after extrusion molding, the pull rod 33 and the upper pressing plate 22 are manually connected; then, the hydraulic cylinder 24 is started to pull the upper pressing plate 22 upward, thereby causing the pull rod 33, the connecting rod 32, the guide rod 31, the lower pressing plate 23 and the formed butter brick M connected to the upper pressing plate 22 to move upward at the same time until the formed butter brick M moves out of the brick mold cavity 21, completing the butter brick production.

[0026] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
