Description

Technical Field

[0001] This utility model relates to the field of tile pressing mold technology, and in particular to a tile pressing mold that is easy to demold. Background Technology

[0002] Easy-release tile pressing molds are specialized tools used to manufacture various corrugated tile sheets. In the brick and tile building materials industry, easy-release tile pressing molds are usually used in conjunction with tile pressing machines. Through mechanical force, the tile blanks are pressed into tiles with specific corrugations, thicknesses, and lengths. Early easy-release tile pressing molds relied mainly on manual operation, had extremely simple structures, and could only meet the needs of small-scale, low-precision tile production. With the advancement of the Industrial Revolution and significant progress in mechanical manufacturing technology, mechanically driven easy-release tile pressing molds began to appear.

[0003] However, existing easy-to-demold tile molds have the following drawbacks:

[0004] 1. After the tiles are formed, due to the tight fit between the tiles and the mold surface, there is a large friction and intermolecular adhesion between the two. It is difficult to ensure the uniformity and stability of the applied force during demolding, resulting in very low demolding efficiency.

[0005] 2. During the demolding process, the edges and corners of the tiles are most susceptible to cracking and chipping due to the concentrated stress. Summary of the Invention

[0006] The purpose of this utility model is to solve the above-mentioned problems by proposing an easy-to-demold tile mold.

[0007] To achieve the above objectives, the following technical solution was adopted:

[0008] An easy-to-demold tile forming mold includes a mold, an air top, an air source system, a sensor, and a control system. The mold includes a mold core and side walls. The mold core has a groove. The air top is installed inside the groove. The air source system includes a solenoid valve and an air compressor. The air source system is connected to the bottom of the mold. The sensor is located inside the tile forming machine. The control system is electrically connected to the sensor and the solenoid valve.

[0009] Preferably, the mold is a concave rectangular box-shaped body surrounded by four side walls, which are tightly connected to each other by screws, and the side walls are not lower than the tile blank.

[0010] Preferably, the bottom of the mold is provided with a base plate, and the base plate is provided with a round hole.

[0011] Preferably, the bottom side of the mold is provided with an air inlet, and the air inlet is connected to the air top through a sealed hose.

[0012] Preferably, a lower mold connecting plate is provided below the mold core, the lower mold connecting plate is connected to the base plate, the lower mold connecting plate is provided with an installation groove, the air top and the hose are located in the installation groove, and the lower mold connecting plate is fixedly connected to the side wall by screws.

[0013] Preferably, the grooves are evenly distributed within the mold core, the diameter of the grooves is smaller than that of the air top, and the grooves correspond one-to-one with the air tops.

[0014] Preferably, the solenoid valve is connected to the air inlet and the air compressor via air pipes.

[0015] Preferably, the sensor is a pressure sensor, installed in the upper cylinder pipeline inside the tile press machine.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The mold utilizes an air ejector, a solenoid valve, and a sensor to achieve efficient demolding. When the tile is pressed, the sensor senses the pressure change in the upper cylinder pipeline and quickly transmits a signal to the control system. After the control system feeds back the command to the solenoid valve, the solenoid valve responds quickly, sending high-pressure gas from the air compressor into the air ejector through the air pipe. Under the action of the gas, the air ejector pushes out from the mold, lifting the tile blank in the mold, making demolding easy and fast, and significantly improving production efficiency.

[0017] This mold uses gas to demold the tile blank, causing less damage to the blank. Moreover, the air top and groove are evenly distributed inside and on the surface of the mold, so that the force is evenly distributed on all parts of the tile. This avoids problems such as tile cracking and scratching caused by uneven force in traditional demolding methods, and effectively reduces the scrap rate. Attached Figure Description

[0024] The following describes a roll forming mold of this utility model with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, an easy-to-demold tile forming mold includes a mold 1, an air top 2, an air source system 3, a sensor 4, and a control system 5. The mold 1 includes a mold core 11 and a side wall 12. The mold core 11 has a groove 13. The air top 2 is installed inside the groove 13. The air source system 3 includes a solenoid valve 31 and an air compressor 32. The air source system 3 is connected to the bottom of the mold 1. The sensor 4 is installed inside the tile forming machine. The control system 5 is electrically connected to the sensor 4 and the solenoid valve 31.

[0026] Preferably, the mold 1 has a concave rectangular box shape and is surrounded by four side walls 12. The side walls 12 are fixedly connected to the mold core 11 by screws, and the side walls 12 are not lower than the tile blank.

[0027] The mold 1 is a concave rectangular box, and the side wall 12 of the mold 1 is higher than the tile blank. This ensures that the tile blank will not be squeezed out of the mold during pressing, thus avoiding deformation of the tile blank during the pressing process and damage to the tile. In addition, the mold core 11 is fixedly connected with screws to prevent the tile blank from seeping out from the corners of the mold and facilitates installation.

[0028] Preferably, the bottom of the mold is provided with a base plate 15, and the base plate 15 is provided with a round hole.

[0029] The bottom of the mold 1 is provided with a base plate 15, and multiple round holes 16 are provided on the base plate 15, which can fix the mold 1 on the worktable of the tile press machine and tighten it with screws to ensure the stability of the tile blank pressing process.

[0030] like Figure 4 As shown, preferably, the bottom side of the mold 1 is provided with an air inlet 14, and the air inlet 14 is connected to the air top 2 by a sealing hose 21.

[0031] Preferably, a lower mold connecting plate 17 is provided below the mold core 11. The lower mold connecting plate 17 is connected to the base plate 15. The lower mold connecting plate 17 is provided with an installation groove 18. The air ejector 2 and the hose 21 are located in the installation groove 18. The lower mold connecting plate 17 is fixedly connected to the side wall 12 by screws.

[0032] An air inlet 14 is provided on the side of the mold, and the air inlet 14 is connected to the bottom of each air ejector 2 through a sealed hose to provide a gas channel for the operation of the air ejector 2 and ensure the normal operation of the air ejector 2. The use of a sealed hose 21 can avoid problems such as air leakage, which would make it difficult to achieve the desired demolding effect. The mounting groove 18 set in the lower mold connecting plate provides sufficient installation space for the sealed hose 21.

[0033] Preferably, the grooves 13 are evenly distributed on the mold core 11, the diameter of the grooves 13 is smaller than that of the air ejector 2, and the grooves 13 correspond one-to-one with the air ejector 2.

[0034] The evenly distributed air top 2 can distribute the lifting force evenly on the bottom of the tile blank, making the demolding process more stable and uniform, avoiding excessive local stress on the tile blank, which can lead to problems such as cracking, deformation and surface scratches.

[0035] like Figure 2 As shown, preferably, the solenoid valve 31 is connected to the air inlet 14 and the air compressor 32 via air pipes.

[0036] like Figure 6 As shown, preferably, sensor 4 is a pressure sensor, which is installed in the upper cylinder pipe 41 inside the tile press machine.

[0037] By placing sensor 4 in the upper cylinder pipeline 41, sensor 4 can sense the pressure changes inside the roll forming machine in real time. When the roll forming machine finishes pressing and the hydraulic cylinder rises upward, sensor 4 can respond immediately and send a signal, thereby affecting the solenoid valve 31 located between the mold and the air compressor through the control system 5. The solenoid valve 31 controls the gas to enter the mold 1. The solenoid valve can flexibly adjust the working parameters of the air jack, including the lifting speed, stroke and pressure, according to different tile shapes, sizes and production requirements, so that it can adapt to the demolding requirements of various types of tiles.

[0038] In this embodiment, the side wall 12 is installed on the mold core 11 and the lower mold connecting plate 17 using screws. When the cut tile blank is fed into the mold 1, the upper mold of the tile press presses downward and presses the tile blank in the mold 1 into shape. After the upper mold of the tile press press rises upward, the pressure in the upper cylinder pipeline 41 of the tile press press changes. The sensor 4 detects the pressure change and sends a signal to the control system 5. After receiving the signal, the control system 5 sends a command to the solenoid valve 31. The solenoid valve 31 receives the command and causes the high-pressure gas in the air compressor 32 to enter the mold 1. The high-pressure gas enters the air top 2 through the air inlet 14 and the sealing hose 21. After the gas enters the air top 2, it causes the air top 2 to move upward and push the pressed tile upward, so that the tile is demolded.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Those skilled in the art may find other optimizations and additional functions in this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
