Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to a novel high-pressure mold for a water tank or a fermentation tank-like blank. Background Art

[0002] A mold is a tool that, under the action of external force, turns a blank into a product of a specific shape and size. Water tanks or fermentation tanks need to be processed and produced with the help of molds. Currently, most molds used to produce water tanks or fermentation tanks are gypsum molds. When using gypsum molds to produce water tanks or fermentation tanks, the blank rolled and formed in the gypsum mold contains a certain amount of moisture. The blank needs to be placed in the gypsum mold for a long enough time so that the moisture in the blank can be fully absorbed by the gypsum mold, so that the blank reaches the required hardness, and can be demolded from the gypsum mold and enter the next process to obtain a qualified blank.

[0003] Since the gypsum mold absorbs the moisture in the blank without discharging it, the moisture absorbed by the gypsum mold gradually reaches saturation, resulting in poor water absorption of the gypsum mold. When production needs to continue, the gypsum mold must be dried before making blanks again, and the drying process takes a lot of time. Therefore, the use of gypsum molds to make blanks has the defects of low efficiency and inability to make blanks continuously. In addition, the existing gypsum molds are easily damaged and have a short lifespan, which restricts the mass production of water tank or fermentation tank blanks. Utility Model Content

[0004] The utility model is to solve the technical problem that the gypsum mold cannot continuously make blanks and the blank making efficiency is low, and provides a new type of high-pressure mold for water tank or fermentation tank blanks. By inflating and pressurizing the blank in the mold, the resin layer absorbs water and the resin layer is vacuumed to slow down the water absorption saturation of the resin layer, so that the resin layer continuously absorbs water, and the water loss and solidification rate of the blank is accelerated. When demolding, the air pipe squeezes out the water in the resin layer to lubricate the blank, facilitate demolding, and be flexible in use.

[0005] The technical solution adopted by the utility model is: to provide a new type of high-pressure mold for a water tank or fermentation tank-like body, a main mold and a bottom mold that can be detachably assembled, air pipes are evenly distributed inside the main mold and the bottom mold, and a positioning groove is coaxially arranged at the bottom end of the bottom mold; the main mold and the bottom mold are sequentially provided with a mold outer frame, a filling layer and a resin layer from the outside to the inside, and the air pipes are evenly distributed between the filling layer and the resin layer.

[0006] When making blanks, the main mold and the bottom mold of the mold are assembled and combined, so that the resin layer of the main mold and the resin layer of the bottom mold form a complete mold cavity. After the assembled main mold and the bottom mold are transferred to the rolling machine, the blank is added to the mold cavity of the resin layer, and the mold outer frame is plugged into the mold table of the rolling machine. The mold outer frame fits the shape of the mold table to make the plug-in firm, thereby improving the rolling forming effect of the blank. The mold outer frame and the filling layer support the resin layer so that the resin layer maintains the structure of the mold cavity, so that the blank can be extended and formed in the resin layer to form a blank. Then the water tank or fermentation tank mold is transferred to the consolidation mechanism for compaction. When the water tank or fermentation tank mold is transported by the transfer vehicle on the production line, the bottom The positioning groove at the bottom of the mold can be plugged into the positioning protrusions such as the positioning pins on the transfer vehicle to fix the position of the water tank or fermentation tank mold, thereby improving the safety of transportation and the accuracy of positioning. After the water tank or fermentation tank mold is transferred to the consolidation mechanism for compression, pressure is applied to the water tank or fermentation tank blank to squeeze out the moisture in the blank and absorb it into the resin layer. The resin layer is vacuumed by evacuating the air pipe to absorb the moisture absorbed by the resin layer, thereby avoiding the resin layer from being saturated with water, and allowing the resin layer to continuously absorb the moisture on the blank, thereby accelerating the curing rate of the blank. During demolding, air is inflated into the air pipe, and the air pipe applies pressure to the resin layer to blow out the moisture absorbed by the resin layer, thereby lubricating the blank and facilitating demolding.

[0007] To further optimize the technical solution, the outer wall of the mold outer frame is provided with at least one air pipe opening, and the air pipe passes through the air pipe opening.

[0008] The trachea is centrally passed through the tracheal opening and is integrated into the same connecting tube, so that the inflation and suction of the trachea can be easily performed, thereby improving the flexibility of use.

[0009] To further optimize the technical solution, a belt is fixedly sleeved on the outer wall of the mold frame, and the belt on the bottom mold is locked and connected to the main mold by means of a locking assembly.

[0010] The belt facilitates the lifting of the main mold and the bottom mold on the production line, and the belt on the bottom mold can be locked and connected with the main mold with the help of a locking component, making the belt flexible and diverse in use.

[0011] To further optimize the technical solution, the locking assembly includes a hook arranged circumferentially on the main mold, and the hook is rotatably installed with the mold frame of the main mold by means of a torsion spring; a connecting ring is slidably installed on the mold frame of the main mold, the inner ring wall of the connecting ring abuts against the hook, and the hook is hung with the belt on the bottom mold.

[0012] The connecting ring moves down along the mold frame of the main mold, so that it pushes the hook to connect with the belt on the bottom mold, thereby locking the main mold and the bottom mold, and the hook pushes the torsion spring to store energy. After the connecting ring moves up along the mold frame, the torsion spring pushes the hook to rotate, so that it is disengaged from the belt on the bottom mold, unlocking the main mold and the bottom mold for easy demoulding.

[0013] To further optimize the technical solution, at least one pair of mold openings are relatively arranged on the outer wall of the mold outer frame.

[0014] The mold turning hole can be connected to a mold turning tool, such as a screw, so as to perform position flipping and adjustment when making the main mold and the bottom mold, which is flexible to use.

[0015] To further optimize the technical solution, the outer wall of the mold frame is provided with locking holes along the circumferential direction.

[0016] The clamping hole can be equipped with a connecting seat and other parts. After the main mold and the bottom mold are closed and transported, the connecting seat is assembled on the clamping hole and fixed on the transport vehicle by bolts, so that the transportation is stable and safe.

[0017] To further optimize the technical solution, the mold outer frame is a carbon steel outer frame.

[0018] Carbon steel is an iron-carbon alloy with low procurement and processing costs. By controlling the carbon content in carbon steel, it has a certain toughness and plasticity, is suitable for various processing techniques, is easy to process and shape, and has a certain strength and corrosion resistance, which improves the support and protection effect on the mold cavity and extends the service life of the mold cavity.

[0019] To further optimize the technical solution, the filling layer is a concrete layer.

[0020] Concrete is made by mixing cement as gel material, sand and stone as aggregates with water in a certain proportion. The cement in the concrete will gradually hydrate and form a viscous slurry after adding water and mixing. After pouring the concrete between the mold frame and the mold cavity, the gap between the mold frame and the mold cavity is filled, and the mold cavity is supported and fixed after the concrete solidifies. The construction is convenient, the concrete layer enhances the protection effect of the mold cavity, and the cost of use is low.

[0021] The beneficial effects of the utility model are:

[0022] 1. After the blank is added to the resin layer, the blank is rolled and formed in the resin layer with the help of a rolling head to make a blank body. The resin layer is wrapped and protected by the mold frame and the filling layer, which improves the safety and reliability of the mold cavity. The mold is hoisted on the production line through the belt on the mold frame, which is flexible to use.

[0023] 2. After the blank is roll-formed in the resin cavity, the blank fits with the surface of the resin cavity, the resin absorbs the moisture in the blank, and inflates and pressurizes the blank to improve the tightness of the blank and the resin cavity, and improve the forming effect and forming accuracy of the blank;

[0024] 3. After the green body is inflated and pressurized, the moisture in the green body is squeezed out, and the resin layer absorbs the moisture squeezed out of the green body, accelerating the water loss rate of the green body. The air pipe sucks the moisture absorbed by the resin layer to avoid the resin layer being saturated with water, so as to continuously absorb the moisture in the green body, increase the curing rate of the green body, and improve the production efficiency;

[0025] 4. After the blank is solidified and formed in the resin layer, air is inflated into the air pipe when the blank is demolded to squeeze out the moisture absorbed in the resin layer so that the moisture can lubricate the blank and facilitate demolding. After demolding, the air pipe is used to discharge the moisture absorbed in the resin layer so that the resin layer can absorb the moisture in the blank and improve production efficiency.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Please see attached Figure 1-5A new type of high-pressure mold for a water tank or fermentation tank blank, including a detachable main mold 1 and a bottom mold 2, the main mold 1 and the bottom mold 2 are sequentially provided with a mold frame 4, a filling layer 5 and a resin layer 6 from the outside to the inside. When the water tank or fermentation tank is made, when the main mold 1 and the bottom mold 2 are hoisted on the production line, the outer wall of the mold frame 4 is fixedly sleeved with a belt 8, and the main mold 1 and the bottom mold 2 are hoisted and transferred on the production line by hanging the belt 8, and the outer wall of the mold frame 4 is relatively provided with at least one pair of mold turning holes 12. When making the main mold 1 and the bottom mold 2, a screw or other mold turning tool is connected to the mold turning hole 12 to adjust the positive and negative positions of the main mold 1 and the bottom mold 2 so as to move the main mold 1 and the bottom mold 2 between the mold frame 4 and the resin layer 6. The filling layer 5 is poured in between, and the use is flexible. When making a water tank or a fermentation tank, the assembled combination of the main mold 1 and the bottom mold 2 is transferred to the rolling press, and the blank is added into the mold cavity of the combined mold of the main mold 1 and the bottom mold 2 after assembly to make the blank. The belt 8 on the bottom mold 2 is locked and connected with the main mold 1 by means of a locking assembly. The locking assembly includes a hook 9 arranged along the circumference of the main mold 1. The hook 9 is rotatably installed with the mold outer frame 4 of the main mold 1 by means of a torsion spring 10, and a connecting ring 11 is slidably installed on the mold outer frame 4. After the main mold 1 and the bottom mold 2 are docked, the connecting ring 11 moves down to push the hook 9 to hang with the belt 8 on the bottom mold 2. The connecting ring 11 constrains the position of the hook 9 to prevent it from bouncing open, so that the lock is firm;

[0034] Please see attached Figure 1-5 When making blanks, the blanks used for making water tanks or fermentation tanks are added to the mold cavity of the resin layer 6 of the combined mold of the main mold 1 and the bottom mold 2, and transferred to the mold table of the rolling machine. The mold outer frame 4 corresponds to the shape of the mold table of the rolling machine, so that they are plugged in tightly, improve the firmness of the plugging, and avoid shaking of the mold outer frame 4, which affects the quality and effect of blank making;

[0035] The mold outer frame 4 is a carbon steel outer frame. The carbon steel outer frame can be made of carbon steel plates commonly used in the market, etc., and is shaped by conventional processes such as forging, pressing, and welding. Carbon steel is an iron-carbon alloy. Carbon elements exist in the form of solid solution in iron. Since carbon atoms are closer to iron atoms, solid solution strengthening effects can be produced, thereby improving the strength and hardness of steel. As the carbon content increases, the number of solid solutions increases, so that the strength and hardness of carbon steel increase accordingly. However, when the carbon content is too high, carbides will precipitate at the grain boundaries of the steel. Although these carbides will enhance the strength and hardness of carbon steel, they will reduce its plasticity and toughness. At the same time, the increase in carbon content will promote the formation of a highly corrosive oxide film on the surface of the steel, accelerate the corrosion process of the steel, and thus reduce the corrosion resistance of the steel. Therefore, the mold outer frame 4 is preferably low-carbon steel to reduce the cost of use, and its low carbon content makes it have good toughness and plasticity, and can be applied to various processing techniques, making it easy to process the mold outer frame 4;

[0036] Please see attached Figure 1-5When the rolling head on the rolling machine presses and extends the blank in the resin layer 6, a filling layer 5 is provided between the mold outer frame 4 and the resin layer 6. The filling layer 5 fills the space and gap between the mold outer frame 4 and the resin layer 6, shapes the resin layer 6, and improves the connection strength between the resin layer 6 and the mold outer frame 4, thereby improving the safety and reliability of the use of the resin layer 6;

[0037] The filling layer 5 is a concrete layer. Concrete is usually made of cement as a gel material, sand and stone as aggregates, and water in a certain proportion and then mixed. After adding water and mixing, the cement in the concrete will gradually hydrate and form a viscous slurry. When pouring concrete between the mold frame 4 and the resin layer 6, the main mold 1 and the bottom mold 2 are turned over so that the concrete can be poured between the mold frame 4 and the resin layer 6. After solidification, the resin layer 6 is supported and fixed. The main mold 1 and the bottom mold 2 are turned over to facilitate mold repair and mold washing operations, thereby improving the flexibility of use. When making blanks, they can be turned over and adjusted again, which is convenient for construction. The concrete layer enhances the protection effect of the resin layer 6, and the use cost is low.

[0038] Please see attached Figure 1-5 After the blank is roll-formed in the resin layer 6, the main mold 1 and the bottom mold 2 are docked to form a complete water cylinder or fermentation cylinder mold. On the production line, when the complete water cylinder or fermentation cylinder mold is transferred to the consolidation mechanism for compaction by a transfer vehicle, a positioning groove 3 is coaxially arranged at the bottom end of the bottom mold 2, and the positioning groove 3 is plugged with positioning protrusions such as positioning pins arranged on the transfer vehicle on the production line, so as to constrain the position of the water cylinder or fermentation cylinder mold and improve the stability and reliability of mold transportation. When the mold is transported externally, a locking hole 13 is circumferentially arranged on the mold outer frame 4, and a connecting seat and other structures are installed in the locking hole 13, and the connecting seat is locked by bolts, so as to lock the mold to prevent it from loosening and dislocation during transportation;

[0039] Please see attached Figure 1-5When the blank is solidified and shaped in the water tank or fermentation tank mold, pressure is applied to the blank to make the blank fit closely with the resin layer 6 to improve its molding effect, and the high pressure squeezes out the moisture in the blank and is absorbed by the resin layer 6. Air pipes are evenly distributed in the main mold 1 and the bottom mold 2, and the air pipes are evenly distributed between the filling layer 5 and the resin layer 6. The outer wall of the mold outer frame 4 is provided with at least one air pipe port 7, and the air pipe passes through the air pipe port 7 to be connected to an external air source. The air pipe is integrated on a connecting pipe to improve the flexibility of use. When the high pressure in the blank squeezes out the moisture, the air pipe is evacuated. Negative pressure is generated on the fat layer 6, so as to suck out the water absorbed in the resin layer 6, so as to avoid the resin layer 6 being saturated with water, so that the resin layer 6 can continuously absorb the water in the green body, and increase the water loss rate of the green body in the water tank or the fermentation tank, and improve the curing molding rate. When demoulding, the air is inflated into the air pipe, and the air pipe squeezes out the water absorbed in the resin layer 6, so that the water lubricates the green body, and the green body is convenient to be separated from the resin layer 6. After demoulding, the air is continuously inflated into the air pipe to completely remove the water in the resin layer 6, so that the resin layer 6 can be used continuously, thereby improving production efficiency.

[0040] The working principle of the new high-pressure mold for the water tank or fermentation tank blank is as follows: the main mold 1 and the bottom mold 2 are hoisted on the production line by the belt 8. When making blanks, the main mold 1 and the bottom mold 2 are assembled together, the hook 9 on the main mold 1 is hooked with the belt 8 on the bottom mold 2, and the hook 9 is constrained in position by the connecting ring 11 to prevent the hook 9 from bouncing off, so that the resin layers 6 on the main mold 1 and the bottom mold 2 are assembled to form a complete mold cavity, thereby forming a complete water tank or fermentation tank mold, and the assembled body of the main mold 1 and the bottom mold 2 is transferred to the roller. After being put on the press, the blank is added into the mold cavity of the resin layer 6. After being rolled by the rolling machine, the blank is extended and formed in the resin layer 6. When the water tank or fermentation tank mold is transported, the connecting seat and other connecting parts are connected to the locking hole 13 on the mold outer frame 4. The connecting seat is tightened and fixed on the transport vehicle of the production line by means of bolts, etc., and the transport vehicle is provided with positioning protrusions such as positioning pins and the like to be plugged into the positioning groove 3 at the bottom end of the bottom mold 2, thereby improving the stability and reliability of the vehicle's support for the water tank or fermentation tank mold and the positioning accuracy;

[0041] When the blank is solidified and formed in the mold, pressure is applied to the blank to make it fit with the resin layer 6, thereby improving its forming effect. The high pressure squeezes out the moisture in the blank and is absorbed by the resin layer 6. The air pipe passing through the air pipe port 7 is connected to the external air source. When the blank is solidified, the air pipe is evacuated, and the air pipe sucks the resin layer 6, so that the moisture absorbed by the resin layer 6 is extracted to avoid the resin layer 6 being saturated with water. In this way, the resin layer 6 can continuously absorb the moisture in the blank, thereby increasing the water loss rate of the blank, accelerating the solidification of the blank, and improving production efficiency.
