Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to a new high-pressure mold for a wine jar 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. Wine jars need to be processed and produced with the help of molds. Currently, most molds used to produce wine jars are plaster molds. When using plaster molds to produce wine jars, the blank rolled into shape in the plaster mold contains a certain amount of moisture. The blank needs to be placed in the plaster mold for a long enough time so that the moisture in the blank can be fully absorbed by the plaster mold, so that the blank reaches the required hardness, and can be demolded from the plaster 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 in 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 wine jar 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 wine jar 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 wine jar blank, including a detachable and assembled upper mold, a middle mold and a bottom mold, air pipes are evenly distributed in the upper mold, the middle mold and the bottom mold, and a positioning groove is coaxially arranged at the bottom end of the bottom mold; the upper mold, the middle 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 upper mold and the middle mold of the wine jar mold are separated, and the middle mold is assembled with the bottom mold. The blanks are added to each resin layer respectively, and the upper mold and the assembly of the middle mold and the bottom mold are transferred to the rolling machine respectively. The mold frame is plugged into the mold table of the rolling machine. The mold frame fits the shape of the mold table to make the plugging firm and improve the rolling forming effect of the blank. The mold 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. After the blank making is completed, the upper mold and the middle mold are docked and assembled to form a complete wine jar mold, and the wine jar mold is transferred to the next process. When the wine jar mold is transported by a transfer vehicle, the positioning groove at the bottom of the bottom mold can be aligned with the bottom mold. The positioning pins and other positioning protrusions on the transfer vehicle are plugged in to fix the position of the wine jar mold, improve the safety of transportation, and ensure accurate positioning. After the wine jar mold is spliced, the blanks in the upper and lower molds are bonded to each other to form a complete wine jar blank. After the wine jar mold is transferred to the consolidation mechanism and pressed tightly, pressure is applied to the wine jar 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. The resin layer continuously absorbs the moisture on the blank, thereby accelerating the curing rate of the blank. When 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, lubricate the blank, and facilitate 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 outer frame, and the belt on the bottom mold is locked and connected to the middle mold by means of a locking assembly.

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

[0011] To further optimize the technical solution, the locking assembly includes a hook circumferentially arranged on the middle mold, and the hook is rotatably installed with the mold outer frame of the middle mold by means of a torsion spring; a connecting ring is slidably installed on the mold outer frame of the middle 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 middle mold, so that it pushes the hook to connect with the belt on the bottom mold, thereby locking the middle 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 lock of the middle mold and the bottom mold, which is convenient for 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 opening hole can be connected with mold opening tools, such as screws, etc. When making the upper mold, the middle mold and the bottom mold, the position thereof can be adjusted to facilitate pouring of the filling layer, and the use is flexible.

[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 locking hole can be equipped with a connecting seat and other parts. When the upper mold, the middle mold and the bottom mold are closed and transported, the connecting seat is assembled on the locking hole and locked with bolts to make the mold closed firmly and the transportation 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 after the upper mold, middle mold and bottom mold are docked, the blank is aligned and bonded, and then air is inflated and pressurized into 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.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Please refer to the attached Figure 1-6A new type of high-pressure mold for a wine jar blank comprises a detachable upper mold 1, a middle mold 2 and a bottom mold 3. The upper mold 1, the middle mold 2 and the bottom mold 3 are sequentially provided with a mold frame 5, a filling layer 6 and a resin layer 7 from the outside to the inside. When the wine jar is made, when the upper mold 1, the middle mold 2 and the bottom mold 3 are hoisted on the production line, the outer wall of the mold frame 5 is fixedly sleeved with a belt 9. By hanging the belt 9, the upper mold 1, the middle mold 2 and the bottom mold 3 are hoisted and transferred on the production line, and at least one pair of mold turning holes 13 are relatively provided on the outer wall of the mold frame 5. The mold turning holes 13 are connected by mold turning tools such as screws. When making the mold, the positive and negative positions of the upper mold 1, the middle mold 2 and the bottom mold 3 are adjusted so as to fill the filling layer. The layer 6 is poured between the mold frame 5 and the resin layer 7. After the filling layer 6 is hardened, it will be flexible to use. When making a wine jar, the blank is added to the upper mold 1 and the assembled combination of the middle mold 2 and the bottom mold 3 respectively to make the blank. The belt 9 on the bottom mold 3 is locked and connected with the middle mold 2 by means of a locking assembly. The locking assembly includes a hook 10 arranged circumferentially on the middle mold 2. The hook 10 is rotatably installed with the mold frame 5 of the middle mold 2 by means of a torsion spring 11, and a connecting ring 12 is slidably installed on the mold frame 5. After the middle mold 2 and the bottom mold 3 are docked, the connecting ring 12 moves down to push the hook 10 to hang with the belt 9 on the bottom mold 3. The connecting ring 12 constrains the position of the hook 10 to prevent it from bouncing open, so that the lock is firm.

[0035] Please refer to the attached Figure 1-6 When making blanks, the blanks used for making the wine jars are added to the resin layer 7 of the upper mold 1 and the resin layer 7 of the middle mold 2 and the chassis assembly, and are transferred to the mold table of the rolling machine respectively. The mold outer frame 5 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 5, which affects the quality and effect of blank making;

[0036] The mold outer frame 5 is a carbon steel outer frame. The carbon steel outer frame can be made of carbon steel plates commonly used in the market, and is shaped by conventional processes such as forging and welding. Carbon steel is an iron-carbon alloy. Carbon elements exist in iron in the form of solid solution. Since carbon atoms have a radius of 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 strengthen 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 5 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, and it is easy to process the mold outer frame 5;

[0037] Please refer to the attached Figure 1-6When the rolling head on the rolling machine presses and extends the blank in the resin layer 7, a filling layer 6 is provided between the mold outer frame 5 and the resin layer 7. The filling layer 6 fills the space and gap between the mold outer frame 5 and the resin layer 7, shapes the resin layer 7, and improves the connection strength between the resin layer 7 and the mold outer frame 5, thereby improving the safety and reliability of the use of the resin layer 7;

[0038] The filling layer 6 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, and the main mold 1 and the bottom mold 2 are turned over to facilitate mold repair, mold washing and other operations, thereby improving the flexibility of use. When making blanks, they are turned over and adjusted again, which is convenient for construction. The concrete layer enhances the protection effect of the resin layer 7, and the use cost is low.

[0039] Please refer to the attached Figure 1-6 After the blank is roll-formed in the resin layer 7, the upper mold 1 is docked with the combination of the middle mold 2 and the bottom mold 3 to form a complete wine jar mold. When the complete wine jar mold is transferred to the consolidation mechanism by a transfer vehicle, the mold is transported. A locking hole 14 is circumferentially arranged on the mold outer frame 5. A connecting seat and other structures are installed in the locking hole 14, and the connecting seat is locked by bolts to lock the mold to prevent it from loosening and dislocation during transportation. A positioning groove 4 is coaxially arranged at the bottom end of the bottom mold 3. The positioning groove 4 is plugged into a positioning protrusion such as a positioning pin arranged on the transfer vehicle to constrain the position of the wine jar mold and improve the stability and reliability of mold transportation.

[0040] Please refer to the attached Figure 1-6When the blank is solidified and shaped in the wine jar mold, air is inflated and pressurized into the blank to make the blank fit closely with the resin layer 7 to improve its molding effect. The high pressure squeezes out the moisture in the blank and is absorbed by the resin layer 7. Air pipes are evenly distributed in the upper mold 1, the middle mold 2 and the bottom mold 3. The air pipes are evenly distributed between the filling layer 6 and the resin layer 7. The outer wall of the mold outer frame 5 is provided with at least one air pipe port 8. The air pipe passes through the air pipe port 8 to connect with 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. , a negative pressure is generated on the resin layer 7, so as to suck out the water absorbed in the resin layer 7, and avoid the resin layer 7 being saturated with water, so that the resin layer 7 can continuously absorb the water in the green body, and increase the water loss rate of the wine jar green body, and increase the curing molding rate. When demoulding, the air pipe is inflated, and the air pipe squeezes out the water absorbed in the resin layer 7, so that the water lubricates the green body, and the green body is convenient to be separated from the resin layer 7. After demoulding, the air pipe is continuously inflated to completely remove the water in the resin layer 7, so that the resin layer 7 can be used continuously, thereby improving production efficiency.

[0041] The working principle of the new high-pressure mold for the wine jar blank is as follows: the upper mold 1, the middle mold 2 and the bottom mold 3 are hoisted on the production line through the belt 9. When making the blank, the hook 10 on the middle mold 2 is hung with the belt 9 on the bottom mold 3, and the connecting ring 12 constrains the position of the hook 10 to prevent the hook 10 from bouncing off, so that it is locked stably and firmly. After the blanks are added into the resin layer 7 respectively, the blanks are rolled by a rolling machine in the resin layer 7 to be extended and formed, and then the combination of the upper mold 1, the middle mold 2 and the bottom mold 3 is joined to form a complete wine jar mold. When the wine jar mold is transported, the connecting seat and other connecting parts are connected to the locking hole 14 on the mold outer frame 5, so as to lock and fix the upper mold 1, the middle mold 2 and the bottom mold 3 to avoid their dislocation and damage to the blank. When the wine jar mold is transferred on the production line, positioning protrusions such as positioning pins are arranged on the transfer vehicle to be plugged into the positioning groove 4 at the bottom end of the bottom mold 3, thereby improving the stability and reliability of the vehicle's support for the wine jar mold.

[0042] When the blank is solidified and formed in the mold, pressure is applied to the blank to make it fit with the resin layer 7, thereby improving its forming effect. The high pressure squeezes out the moisture in the blank and is absorbed by the resin layer 7. The air pipe passing through the air pipe port 8 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 7, so that the moisture absorbed by the resin layer 7 is extracted to avoid the resin layer 7 being saturated with water. In this way, the resin layer 7 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.
