Description

Technical Field

[0001] The utility model belongs to the technical field of brick pressing mould design, and particularly relates to a novel brick pressing mould with an exhaust function. Background Art

[0002] Brick pressing molds are a key component used in the production of brick products, and they directly affect the quality and production efficiency of bricks. At present, brick press manufacturers need to exhaust the gas in the powder through the gap between the upper mold and the side plate of the lower mold cavity when pressing bricks. In order to fully exhaust the gas, the upper mold is usually lifted a certain distance during the pressing and exhausting stage to expand the exhaust gap channel between the upper mold and the side plate of the lower mold cavity. After staying for a period of time, the upper mold is pressed down again. On the one hand, this operation method has the problem of low brick pressing efficiency due to the frequent lifting of the upper mold. On the other hand, when the upper mold moves downward, some of the gas in the mold cavity cannot be discharged, resulting in poor quality of brick molding. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a new brick pressing mold with an exhaust function, which realizes the rapid exhaust effect during the brick pressing process by evenly opening exhaust channels on the surface of the top plate, and the aperture of the exhaust channel is designed to be smaller at the end close to the powder and larger at the end away from the powder, so as to quickly exhaust without affecting the quality of brick forming. It has the advantages of high work efficiency and good brick forming quality.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] As shown in the figure, a new brick pressing mold with exhaust function includes a top plate 1, a bottom plate 2, two side plates 3 and two blocking plates 4. The two side plates 3 are arranged on both sides of the bottom plate 2, and the two blocking plates 4 are arranged at both ends of the bottom plate 2. The top plate 1 is movably arranged in the space formed by the bottom plate 2, the side plates 3 and the blocking plates 4. When working, the bottom plate 2, the side plates 3 and the blocking plates 4 are installed in the mold frame, and the top plate 1 is installed on the pressing plate of the brick press. The space formed by the bottom plate 2, the side plates 3 and the blocking plates 4 can be filled with powder. The powder can be compacted during the downward movement of the top plate 1, thereby forming the brick blank.

[0023] At least one concave exhaust groove 101 is provided on the upper surface of the top plate 1. The purpose of providing the exhaust groove 101 is to prevent the exhaust passage 102 from being blocked after the pressure plate and the top plate 1 are connected since the top plate 1 needs to be connected to the pressure plate of the brick press. The two ends of the exhaust groove 101 pass through the two side walls of the top plate 1. At the root of the exhaust groove 101, there are multiple exhaust passages 102 that pass through the thickness direction of the top plate 1. The aperture of the exhaust passage 102 gradually increases from the bottom surface to the top surface of the top plate 1. When the top plate 1 is working, it has an up and down movement state. During the process of its downward movement to press the brick raw materials, the air in the space below the top plate 1 can enter the exhaust groove 101 from the exhaust passage 102 and finally complete the exhaust work.

[0024] The above structure uses the exhaust channel 102 to connect the upper space of the top plate 1 with the lower space when the bricks are made, so that during the brick pressing process, the air inside the mold cavity can enter the exhaust groove 101 from the exhaust channel 102, thereby achieving the exhaust effect. Since the aperture of the exhaust channel 102 is larger at the top and smaller at the bottom, the purpose of the exhaust channel 102 can be achieved.

[0025] In this example, the exhaust channel 102 includes a first-level exhaust hole 1021 and a second-level exhaust hole 1022 that are coaxial and interconnected. The aperture of the first-level exhaust hole 1021 is smaller than that of the second-level exhaust hole 1022, and the first-level exhaust hole 1021 is arranged on the side close to the lower surface of the top plate 1. In this example, the aperture of the first-level exhaust hole 1021 is smaller than that of the second-level exhaust hole 1022. The purpose is to avoid excessive powder from entering the exhaust channel 102 during the brick pressing process, thereby avoiding adverse effects on the forming of the brick blanks. On the other hand, in the process of gas entering the second-level exhaust hole 1022 from the first-level exhaust hole 1021, the aperture suddenly increases, thereby reducing the air pressure entering the second-level exhaust hole 1022, which is more conducive to gas discharge.

[0026] Specifically, the height of the first-level exhaust hole 1021 is smaller than the height of the second-level exhaust hole 1022. The aperture of the first-level exhaust hole 1021 is 5-6 mm, and the height is 5-7 mm. In this example, the aperture of the first-level exhaust hole 1021 is 6 mm, and the height is 5 mm. Different aperture and height dimensions can also be designed according to the actual thickness and actual width of the top plate 1.

[0027] The plurality of exhaust channels 102 are distributed at equal intervals in the exhaust slot 101 . Specifically, the spacing between two adjacent exhaust channels 102 is 50-60 mm. Exhaust channels 102 with different spacings can be designed according to the actual size of the top plate 1 .

[0028] When the number of the exhaust grooves 101 is greater than or equal to two, the multiple exhaust grooves 101 are evenly distributed on the surface of the top plate 1. When the number of the exhaust grooves 101 is one, the exhaust groove 101 is located in the middle of the top plate 1. The number of the exhaust grooves 101 is also specifically designed according to the actual size of the top plate 1, for example:

[0029] When the width of the top plate 1 is less than 160 mm, only one exhaust groove 101 is designed in the middle;

[0030] When the width of the top plate 1 is 161-200 mm, two or three exhaust slots 101 may be evenly distributed on the top plate 1;

[0031] When the width of the top plate 1 is 201-300 mm, three exhaust slots 101 may be evenly distributed on the top plate 1;

[0032] When the width of the top plate 1 is 301-400 mm, five exhaust slots 101 may be evenly distributed on the top plate 1;

[0033] When the width of the top plate 1 is 401-550 mm, seven exhaust slots 101 can be evenly distributed on the top plate 1 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
