Description

Technical Field

[0001] The utility model belongs to the technical field of brick tea processing and relates to a brick tea pressing mould. Background Art

[0002] Green brick tea is made by stacking tea leaves after three layers of steaming and pressing them into block tea in a mold. Since the mold is an assembled structure, burrs are easily formed at the edges and corners of the brick tea corresponding to the joints. Therefore, after the green brick tea is demolded, it needs to be deburred, and the deburring process needs to be performed multiple times (each time two edges of the tea brick are deburred online, and the tea brick has a total of 12 edges). Therefore, the existing tea brick pressing mold requires post-processing (trimming) after pressing, which is costly. Utility Model Content

[0003] The purpose of the utility model is to provide a brick tea pressing mold in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is how to reduce the workload of deburring the brick tea after forming and improve the appearance quality of the tea brick.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a brick tea pressing mold, characterized in that it includes an outer frame, a bottom mold and a pressing plate, the inner side surfaces of the four side panels of the outer frame are all inclined surfaces, and the inner side surface of the outer frame is inclined at an angle of 83 to 87 degrees to the horizontal plane, the bottom mold includes a bottom plate and a mold frame located at the outer edge of the bottom plate, the outer side surfaces of the four side panels of the mold frame are respectively adapted to the inner side surfaces of the four side panels of the outer frame, a diaphragm with deformation ability is connected to the upper opening of the outer frame, the diaphragm is concave, and the pressing plate is adapted to the upper end opening of the outer frame.

[0005] Furthermore, the upper opening of the outer frame is provided with a mounting step, the edge of the diaphragm is fixed at the mounting step, and the pressure plate is adapted to the mounting step.

[0006] Furthermore, the membrane is a silicone sheet.

[0007] During operation, first take out the pressing plate and the bottom mold, fill the steamed tea leaves into the concave diaphragm, and fill it until the lower end of the diaphragm is beyond the outer frame, that is to say, the filling volume must be larger than the volume of the brick tea after forming. During the filling process, the diaphragm is deformed and expanded. After the filling is completed, close the pressing plate, invert the outer frame, so that the pressing plate is at the bottom, and then insert the bottom mold. The wedge-shaped structure between the outer side surface of the bottom mold and the inner side surface of the outer frame has a guiding effect on the cooperation between the two. During the process of pressing into the bottom mold, the diaphragm slowly deforms until the diaphragm fits the inner wall surface of the bottom mold and the inner side surface of the pressing plate, and the pressing state is maintained. The residual liquid in the pressing process is discharged from the gap between the pressing plate and the outer frame. After cooling and forming, the mold is disassembled in reverse to realize the demolding of the brick tea. The tea bricks pressed in this way have burrs only on four edges, and the parts in contact with the diaphragm are all smooth transition edges and corners, which greatly reduces the workload of removing burrs.

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, the brick tea pressing mold includes an outer frame 1, a bottom mold 2 and a pressing plate 3. The inner side surfaces of the four side panels of the outer frame 1 are all inclined surfaces, and the inner side surface of the outer frame 1 is inclined at an angle of 83 to 87 degrees to the horizontal plane. The bottom mold 2 includes a bottom plate and a mold frame located at the outer edge of the bottom plate. The outer side surfaces of the four side panels of the mold frame are respectively adapted to the inner side surfaces of the four side panels of the outer frame 1. A diaphragm 4 with deformation ability is connected to the upper opening of the outer frame 1, and the diaphragm 4 is concave. The pressing plate 3 is adapted to the upper end opening of the outer frame 1, and the diaphragm 4 is a silicone sheet.

[0014] The upper opening of the outer frame 1 is provided with a mounting step 5 , the edge of the diaphragm 4 is fixed on the mounting step 5 , and the pressing plate 3 is adapted to the mounting step 5 . During operation, first take out the pressing plate 3 and the bottom mold 2, fill the steamed tea leaves into the concave diaphragm 4, and fill it until the lower end of the diaphragm 4 exceeds the outer frame 1, that is, the filling volume must be larger than the volume of the brick tea after molding. During the filling process, the diaphragm 4 is deformed and expanded. After the filling is completed, the pressing plate 3 is closed, the outer frame 1 is inverted, so that the pressing plate 3 is located at the bottom, and then the bottom mold 2 is inserted. The wedge-shaped structure between the outer side surface of the bottom mold 2 and the inner side surface of the outer frame 1 has a guiding effect on the cooperation between the two. During the process of pressing into the bottom mold 2, the diaphragm 4 slowly deforms until the diaphragm 4 fits the inner wall surface of the bottom mold 2 and the inner side surface of the pressing plate 3, and the pressing state is maintained. The residual liquid in the pressing process is discharged from the gap between the pressing plate 3 and the outer frame 1. After cooling and forming, the mold is disassembled in reverse to realize the demoulding of the brick tea. The tea brick pressed and formed in this way has burrs on only four edges, and the parts in contact with the diaphragm 4 are all smooth transition edges and corners, which greatly reduces the workload of removing burrs.

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
