Description

Technical Field

[0001] This invention relates to the field of thermal battery processing technology, and in particular to a casting mold for processing thermal battery casings. Background Technology

[0002] Casting molds for thermal battery casings are specialized molding tools used in the casting process of thermal battery metal casings to define the shape, size, and precision of the casing, allowing molten metal to cool and solidify in the mold cavity to form thermal battery casing products that meet design requirements.

[0003] During the processing of existing casting molds for thermal battery casings, a large amount of gas exists inside the mold. Even with venting channels, only a portion of the gas at the end of the cavity can be discharged. Bubbles trapped inside the metal are compressed under high pressure but cannot be expelled, ultimately resulting in numerous pores inside the product. At the same time, molten aluminum shrinks by about 5%-7% in volume as it changes from liquid to solid. Traditional molds rely on a single far-end gate and limited holding pressure for feeding, but the feeding channels often solidify and become blocked prematurely, resulting in low feeding efficiency and defects such as shrinkage cavities and porosity in the castings. In addition, traditional cooling systems often use straight water channels, resulting in uneven cooling coverage and large local temperature differences in the mold, which can easily lead to problems such as casting deformation, surface hot cracks, and internal stress concentration, affecting the dimensional stability and surface quality of the product.

[0004] Therefore, this application provides a casting mold for processing thermal battery casings to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a casting mold for processing thermal battery casing, so as to solve the problems that the gas inside the existing cavity cannot be completely discharged, the molten metal shrinks a certain volume when solidifying, and the traditional cooling system mostly uses straight water channels, resulting in uneven cooling coverage.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A casting mold for processing a thermal battery casing includes: a mold body; a fixed mold at the top of the mold body; a movable mold at the bottom of the fixed mold; gates at the bottom of all four sides of the fixed mold; cavities at the center of the contact surfaces of the fixed mold and the movable mold; venting grooves at the four outer corners and one pair of sides of the two cavities; an auxiliary casting assembly inside the bottom of the fixed mold for assisting in casting materials; a vacuum extraction assembly outside the auxiliary casting assembly for extracting gas from the cavity; and a condensation assembly at the bottom of the movable mold for cooling the movable mold.

[0008] Optionally, the auxiliary casting assembly includes four feed holes, which are respectively opened at the center lines around the fixed mold. The other end of the four feed holes is connected to an annular liquid hole, and the four corners and a pair of side center lines of the annular liquid hole are connected to a first gradually expanding hole.

[0009] Optionally, the auxiliary casting assembly further includes six I-shaped cavities, each of which is connected to the other end of the first gradually expanding hole. A piston mechanism is installed at the top of the interior of each I-shaped cavity, and an inclined injection hole is connected to the bottom of each I-shaped cavity. Each inclined injection hole is connected to the inner wall of the cavity, and an exhaust hole is connected to the interior of each I-shaped cavity.

[0010] Optionally, the vacuum pumping assembly includes four air guide pipes, which are fixedly connected to the center lines around the fixed mold. The other end of each of the four air guide pipes is connected to an annular air guide hole, which is connected to the other end of each exhaust hole. The four corners and a pair of side center lines of the annular air guide hole are connected to a first inclined air hole.

[0011] Optionally, the vacuum pumping assembly further includes six buffer chambers, each connected to the top of the first inclined air hole, and a vacuum sensor is fixedly connected to the inner wall of each buffer chamber.

[0012] Optionally, the vacuum pumping assembly further includes six second inclined air holes, which are respectively connected to the four corners of the annular air guide hole and a pair of side center lines. The number of second inclined air holes is the same as that of the first inclined air holes, and they correspond one-to-one. The bottom end of each second inclined air hole is connected to the exhaust groove.

[0013] Optionally, the condensation assembly includes a liquid inlet hole located at the center of the bottom end of the moving mold, and the other end of the liquid inlet hole is symmetrically connected to a second gradually expanding hole.

[0014] Optionally, the condensation assembly further includes a plurality of fishbone-shaped cooling holes, which are respectively connected to the interior of the second gradually expanding holes. The ends of the two second gradually expanding holes are respectively connected to steam collection chambers through inclined small holes, and the two steam collection chambers are respectively connected to the ends of the fishbone-shaped cooling holes through inclined small holes.

[0015] Optionally, the condensation assembly further includes two condensation chambers, which are respectively connected to a steam collection chamber. A condensation plate is fixedly connected to the inner wall of the top of each of the two condensation chambers. Each condensation plate has several guide grooves on one side and several condensation holes on the other side.

[0016] Optionally, the condensation assembly further includes two U-shaped grooves, which are respectively connected to the bottom end of the condensation chamber and are respectively connected to the interior of the fishbone-shaped cooling holes. The other ends of the two U-shaped grooves are respectively connected to the liquid inlet of the circulation pump through pipes, and the liquid outlet of the circulation pump is connected to the liquid inlet.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, a vacuum pumping system connected to the venting channels is used to extract gas from the cavity before pouring, reducing air bubble retention and improving the density of the shell. The venting channels are located at the four corners and sides of the cavity, and together with the inclined gate, they facilitate the orderly discharge of gas and prevent air entrapment. At the same time, a vacuum sensor monitors the pressure inside the buffer cavity in real time to ensure that the cavity reaches the target vacuum level before pouring, improving process controllability. Through multiple I-shaped cavities and piston mechanisms, local pressure can be applied to areas that have not yet fully solidified in the later stages of pouring to compact the material and reduce shrinkage cavities and porosity. Meanwhile, a micro valve is installed in the venting port to realize automatic switching between the material storage and pouring stages, improving the degree of automation of the operation.

[0019] In the above solution, by using fishbone-shaped cooling holes to cover all corners and hot spots of the mold, the cooling contact area is significantly increased, achieving uniform cooling and avoiding product deformation or thermal stress cracks caused by excessive temperature differences. At the same time, the coolant boils and absorbs heat in the fishbone-shaped pipes, and the steam is introduced into the condensation chamber through the collection chamber to re-liquefy. The circulating pump achieves efficient heat exchange, and the cooling efficiency is higher than that of traditional water temperature rise methods. Furthermore, through the use of micro flow sensors and temperature sensors, the coolant flow and temperature can be adjusted in real time to achieve precise temperature control, thereby uniformly and stably cooling the mold and improving the cooling efficiency of the entire device.

Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0033] The following is a detailed description of a casting mold for processing a thermal battery casing provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0034] like Figures 1 to 9As shown, an embodiment of the present invention provides a casting mold for processing a thermal battery casing, comprising: a mold body 1, a fixed mold 2 disposed at the top of the interior of the mold body 1, a movable mold 3 disposed at the bottom of the interior of the fixed mold 2, and gates 4 being provided at the bottom of all four sides of the fixed mold 2. Each gate 4 is inclined in the horizontal direction to guide the material to the adjacent side wall, and each gate 4 is inclined downward in the vertical direction to allow the liquid to rise upward along the side wall during casting, thereby filling the cavity 9. A cavity 9 is provided at the center of the contact surface of the fixed mold 2 and the movable mold 3, and openings are provided at the four outer corners and a pair of sides of the two cavities 9. The mold is equipped with venting grooves 8, which are located on the parting surface outside the cavity 9. The venting grooves 8 at the four corners of the cavity 9 are all rounded. An auxiliary pouring assembly 5 is provided inside the bottom of the fixed mold 2. The auxiliary pouring assembly 5 is used to assist in pouring materials. The auxiliary pouring assembly 5 uses huge static pressure to compact the casting that has not yet fully solidified, which is beneficial to improving the airtightness and mechanical properties of the battery casing. A vacuum pumping assembly 6 is provided outside the auxiliary pouring assembly 5. The vacuum pumping assembly 6 is used to extract the gas inside the cavity 9. A condensation assembly 7 is provided inside the bottom of the moving mold 3. The condensation assembly 7 is used to cool the moving mold 3.

[0035] like Figures 2 to 6As shown, the auxiliary gating assembly 5 includes four feed holes 501, which are respectively opened at the center lines of the four sides of the fixed mold 2. The other end of the four feed holes 501 is connected to annular liquid holes 502. The four corners and a pair of side center lines of the annular liquid holes 502 are connected to first expanding holes 503. The first expanding holes 503 are tapered with a small slope. The expanded cavity forms a pressure buffer, reduces the resistance of the liquid, and avoids turbulence. At the same time, the expanding structure of the expanding holes makes the material form a pressure stabilizing layer in the cavity, ensuring that the pressure is evenly transmitted to the cavity 9 during subsequent mold filling. The auxiliary gating assembly 5 also includes six I-shaped cavities 504. The I-shaped cavity 504 is composed of an injection cavity, a connecting hole, and a storage cavity. The diameter of the connecting hole in the middle is smaller than that of the injection cavity and the storage cavity. The top of the storage cavity is connected to the vent hole 507. A micro valve is installed inside the vent hole 507. When storage is required, the liquid inside the annular liquid hole 502 enters through the first expanding holes 503. The material enters the storage chamber, at which point the micro valve is open. The gas inside the storage chamber is discharged into the annular air guide hole 602 through the exhaust hole 507 under the pressure of the rising material. When injection is performed after storage, the micro valve inside the exhaust hole 507 is closed, making the interior of the H-shaped cavity 504 sealed. Then, the piston mechanism 505 is activated to pressurize the material, causing it to be injected into the cavity 9 through the inclined injection hole 506. Each H-shaped cavity 504 is connected to the other end of the first gradually expanding hole 503. A piston mechanism 505 is installed at the top of the interior of each H-shaped cavity 504. The piston mechanism 505 consists of a hydraulic rod and a piston. The hydraulic rod drives the piston to compress and achieve the purpose of injection. The bottom of each H-shaped cavity 504 is connected to the inclined injection hole 506, and each inclined injection hole 506 is connected to the inner wall of the cavity 9. The interior of each H-shaped cavity 504 is connected to the exhaust hole 507.

[0036] like Figures 3 to 6As shown, the vacuum pumping assembly 6 includes four air guide pipes 601, which are fixedly connected to the center lines of the four sides of the fixed mold 2. The other ends of the four air guide pipes 601 are connected to annular air guide holes 602. The four corners of the annular air guide holes 602 are inclined and slightly lower than the straight pipe sections, which helps to guide and collect water vapor inside the pipes during exhaust. At the same time, collection cavities are opened at the bottom of each of the four corners of the annular air guide holes 602. The diameter of the top end of the collection cavity is the same as the diameter of the cavity of the annular air guide hole 602, with a larger diameter in the middle section and a smaller diameter at the bottom, which facilitates connection to the annular air guide holes 602 and avoids water vapor residue. The bottom of the collection cavity is connected to the discharge pipe for easy discharge. Each annular air guide hole 602 is connected to the other end of each exhaust hole 507. The four corners and a pair of side center lines of the air guide hole 602 are all connected to the first inclined air holes 603. The vacuum pumping assembly 6 also includes six buffer chambers 604, which are respectively connected to the top of the first inclined air holes 603. A vacuum sensor 605 is fixedly connected to the inner wall of each buffer chamber 604. The vacuum pumping assembly 6 also includes six second inclined air holes 606, which are respectively connected to the four corners and a pair of side center lines of the annular air guide hole 602. The number of second inclined air holes 606 is the same as that of the first inclined air holes 603, and they correspond one-to-one. The bottom end of each second inclined air hole 606 is connected to the exhaust groove 8. A filter screen is installed at the connection position between the second inclined air hole 606 and the exhaust groove 8 to filter impurities carried in the gas during exhaust.

[0037] like Figures 2 to 10As shown, the condenser assembly 7 includes a liquid inlet 701, which is located at the center of the bottom of the moving mold 3. The other end of the liquid inlet 701 is symmetrically connected to a second gradually expanding orifice 702. Each second gradually expanding orifice 702 is equipped with a miniature flow sensor to monitor the flow rate of the diverted liquid. The diameter of the second gradually expanding orifice 702 is smaller at the connection point with the liquid inlet 701 and larger at the connection point with the U-shaped groove 706. Furthermore, its surface has a gentle slope. Through its gradually expanding characteristic, it guides the steam upwards at an angle, while the cooling water, under the influence of gravity, is guided downwards at an angle, thus facilitating gas-liquid separation. The condenser assembly 7 also includes several fishbone-shaped cooling holes 703. Each of the fishbone-shaped cooling holes 703 is connected to the interior of the second gradually expanding holes 702. The ends of the two second gradually expanding holes 702 are connected to steam collecting chambers 704 through inclined small holes. The steam collecting chambers 704 have a U-shaped structure with an upward-sloping top surface and a small inclination, which facilitates the guidance of steam into the condensation chamber 705. The two steam collecting chambers 704 are connected to the ends of the fishbone-shaped cooling holes 703 through inclined small holes. The fishbone-shaped cooling holes 703 penetrate into various areas of the mold steel through numerous small branch pipes, making it easy to cover corners and narrow areas that are difficult to cover by traditional straight water channels, thereby greatly increasing the contact surface area between the cooling water and the high-temperature mold. Simultaneously, the branch channels guide and distribute the cooling water flow to each local hot spot requiring cooling, while carrying away heat. This structure effectively reduces the temperature difference on the mold surface, preventing problems such as product deformation, thermal stress cracks, and shrinkage cavities caused by uneven cooling. Furthermore, the slightly inclined pipe design facilitates steam extraction. The condensing assembly 7 also includes two condensing chambers 705, each connected to a steam collection chamber 704. A condensing plate 707 is fixedly connected to the inner wall of the top of each of the two condensing chambers 705. Each condensing plate 707 has several guide channels 708 on one side, with a herringbone structure to ensure efficient and directional collection and extraction of condensate. On the other side of the condensing plate 707, several condensing holes 709 are provided. The condensing assembly 7 also includes two U-shaped grooves 706, which are respectively connected to the bottom end of the condensing chamber 705. The two U-shaped grooves 706 are respectively connected to the interior of the fishbone-shaped cooling holes 703. The other end of the two U-shaped grooves 706 are respectively connected to the inlet of the circulating pump 710 through pipes. The outlet of the circulating pump 710 is connected to the inlet hole 701. The bottom end of the U-shaped groove 706 is slightly inclined towards the outlet pipe 710 to facilitate the guidance of cooling water. The inlet hole 701 is equipped with a temperature sensor to facilitate the control of the mold temperature. When the coolant is pumped into the inlet hole 701, after being stabilized by the second gradually expanding hole 702, it enters the fishbone-shaped cooling holes 703. The fishbone-shaped cooling holes 703 are closely attached to the back of the cavity 9 like dense capillaries. When the heat of the high-temperature mold is transferred into the interior of the cooling holes,The coolant rapidly rises to its boiling point at its operating pressure and boils violently on the pipe wall, generating a large number of steam bubbles. This process absorbs a huge amount of latent heat of vaporization, making it far more efficient than traditional cooling methods that rely on increasing water temperature. The resulting vapor-liquid mixture, guided by the designed flow channel inclination, naturally converges towards the highest point at the end of the pipe. At this point, due to its low density, the steam actively rises through the inclined pipe and enters the steam collection chamber 704, achieving separation of the steam from the unevaporated liquid working fluid. After the steam passes through the steam collection chamber 704 and is introduced into the condensation chamber 705, the high-temperature steam enters the condensation chamber 705 and... The internally installed condenser plate 707 contacts the cooling water inside the condenser hole 709 on one side of the condenser plate 707. The low-temperature surface of the cooling water causes the vapor to condense rapidly, turning it back into liquid and releasing the previously absorbed latent heat. Simultaneously, it flows down from the condensation chamber 705, forming fresh coolant that collects in the U-shaped channel 706 along with the unevaporated coolant. The inclined bottom of the U-shaped channel 706 ensures that the liquid flows to the outlet without residue. At this point, the circulation pump draws the collected liquid working fluid from the outlet of the U-shaped channel 706, pressurizes it, and pumps it back to the inlet 701, thus completing a full phase change evaporation cycle.

[0038] The working principle of the technical solution provided by this invention is as follows:

[0039] During operation, the vacuum pump's inlet is connected to the gas guide pipe 601 via a pipe. The vacuum pump is started, allowing gas inside the cavity 9 to enter the second inclined air hole 606 through the exhaust groove 8. The gas is then guided through the second inclined air hole 606 into the annular gas guide hole 602, and finally discharged through the gas guide pipe 601. Simultaneously, excess gas is guided through the first inclined air hole 603 into the buffer chamber 604 for buffering. When the vacuum sensor 605 inside the buffer chamber 604 detects the target pressure value, material is introduced into each gate 4. The material is guided through the gate 4 and then rises gradually along its adjacent sidewalls, where it is poured. During the pouring process, material is introduced into the feed hole 501, allowing it to enter the annular liquid hole 502. The material is then directed through the annular liquid hole 502 into the first gradually expanding hole 503, and then through the first gradually expanding hole 503 into the storage cavity at the bottom of the I-shaped cavity 504. Just before pouring is complete, the piston mechanism 505 is activated, compressing the material in the storage cavity downwards. This forces the material through the inclined injection hole 506 into the cavity 9 and guides it to the corresponding sidewall, thus compensating for shrinkage and compacting the metal. Subsequently, the cooling system at the top of the fixed mold 2 is activated for cooling, while simultaneously feeding material into the feed hole 701. The condensate is introduced into the second gradually expanding hole 702 through the liquid inlet 701, and then into the fishbone-shaped cooling hole 703 through the second gradually expanding hole 702. The moving mold 3 is cooled by the fishbone-shaped cooling hole 703 and the condensate inside it. After cooling is complete, some of the condensate evaporates and vaporizes. The vaporized droplets are guided by the second gradually expanding hole 702 and the fishbone-shaped cooling hole 703 and enter the steam collecting chamber 704 through the inclined hole. The steam collecting chamber 704 then guides the vaporized droplets to move to the cooling chamber. Inside the condensation chamber 705, condensate water is simultaneously introduced into the condensation hole 709. The condensate water in the condensation hole 709 cools the condensation plate 707, which in turn cools the vaporized droplets inside the condensation chamber 705, causing them to liquefy. The droplets are then guided downwards by the guide groove 708, allowing them to fall into the U-shaped groove 706. Meanwhile, the unvaporized condensate enters the U-shaped groove 706 and collects with the droplets. The collected liquid is then piped through the U-shaped groove 706 into the circulation pump 710, which then reintroduces the liquid into the inlet hole 701, thus achieving the cooling purpose.
