Description

Technical Field

[0001] This invention relates to the field of titanium alloy processing technology, and specifically to a shaping mold for hollow titanium alloy rotating structures. Background Technology

[0002] In the field of forming and processing hollow parts of titanium alloy rotating structures, molds are key equipment for achieving precise forming of parts.

[0003] Traditional forming molds rely heavily on manual movement or simple transmission structures for mold base movement, resulting in poor accuracy and stability. This makes them unsuitable for the high-precision forming requirements of titanium alloy parts, easily leading to significant dimensional deviations after forming. During operation, the mold generates substantial vibrations due to pressure and other factors. Existing mold damping structures are relatively simple, typically using only a single spring or rubber pad, offering limited damping effectiveness. This not only affects the mold's lifespan but can also negatively impact the forming quality of parts, such as causing surface defects. Furthermore, the guiding structure design of traditional molds is inadequate during mold closing. Misalignment and wobbling of the upper mold cover during closing can lead to low closing accuracy, affecting the forming precision of hollow titanium alloy rotating parts and increasing the defect rate. Finally, demolding after forming the titanium alloy parts is often difficult. Some molds lack effective demolding aids, requiring manual demolding, which is not only inefficient but may also damage the molded parts during the demolding process, increasing production and time costs. When used in production workshops and other environments, molds lack effective protective structures, making them susceptible to interference and damage from external factors. This may also pose a certain threat to the safety of operators, reducing the safety and reliability of mold use.

[0004] Therefore, it is necessary to design a molding die for hollow titanium alloy rotating bodies to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing titanium alloy rotating hollow component shaping molds, such as poor stability, inaccurate guidance, difficulty in demolding, low temperature control accuracy, and insufficient protective performance, and to provide a titanium alloy rotating hollow component shaping mold.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A molding die for a hollow part of a titanium alloy rotating structure includes a base, a bearing seat, a demolding auxiliary component, a lower mold base, a mold base moving component, a mold base shock absorption component, a top plate, a power supply device, a drive cylinder, a connecting frame, an upper mold cover, side reinforcing steel, a mold cover guide component, a mold cavity, a cooling component, and a heating component. The support seat is positioned above the base, the demolding auxiliary component is fixed above the support seat, and the lower mold base is positioned above the demolding auxiliary component. The support seat and the base are connected by a mold base moving component, which includes a mold base moving track and a mold base moving slider. The mold base moving track is positioned on the base, and the mold base moving slider is connected to the bottom of the support seat and slides in cooperation with the mold base moving track. The mold base moving component enables the support seat to move the lower mold base along the base, facilitating the adjustment of the lower mold base's position and simplifying loading and unloading operations. A mold base vibration damping assembly is provided between the lower left and right sides of the lower mold base and the top of the left and right sides of the support seat. The mold base vibration damping assembly includes a damping column and a spring. The spring is sleeved and installed around the damping column, and the top and bottom of the damping column are fixedly connected to the lower mold base and the support seat with nuts. Both the damping column and the spring are located between the support seat and the lower mold base. During the mold closing and forming process, the mold base vibration damping assembly can effectively absorb vibration energy, reduce the impact of vibration on the mold and product forming accuracy, and improve the stability and service life of the mold. The top plate is positioned above the forming mold. The power supply device and drive cylinder are located on the top of the top plate. The connecting frame and upper mold cover are located at the bottom output end of the drive cylinder and below the top plate. The side reinforcing steel is fixedly installed on the left and right sides between the base and the top plate. The drive cylinder can drive the connecting frame to move the upper mold cover up and down, realizing the mold closing and opening actions. The side reinforcing steel can enhance the overall structural strength of the mold and improve the load-bearing capacity of the mold. A mold cover guide assembly is provided between the left and right sides of the connecting frame and the inner wall of the side reinforcing steel. The mold cover guide assembly includes a mold guide slider and a mold guide rail. The mold guide rail is set on the inner wall of the side reinforcing steel. The mold guide slider is connected to the connecting frame and slides with the mold guide rail. When the connecting frame drives the upper mold cover to move up and down, the mold cover guide assembly can ensure that the upper mold cover moves along a fixed trajectory, avoids deviation, ensures mold closing accuracy, and improves product molding quality. A mold cavity is provided above the lower mold base corresponding to the upper mold cover. The mold cavity is the forming space for the hollow titanium alloy rotating body structure. Cooling components and heating components are respectively set on the periphery of the mold cavity and inside the upper mold cover. Through the synergistic effect of the heating components and cooling components, the temperature of the mold cavity can be precisely controlled to meet the forming temperature requirements of the hollow titanium alloy rotating body structure.

[0007] Furthermore, the demolding auxiliary component includes a demolding cylinder and an ejector block connected to the upper output end of the demolding cylinder. Driven by the demolding cylinder, the ejector block is used to push the hollow titanium alloy rotating structure after molding to achieve demolding. After the product is molded, the demolding cylinder drives the ejector block to move upward, ejecting the molded part from the mold cavity, avoiding the molded part from sticking to the cavity, achieving convenient and non-destructive demolding, and improving production efficiency and product qualification rate.

[0008] Furthermore, the cooling assembly includes a coolant storage chamber, a cooling water path, and a micro pump. The coolant storage chamber stores coolant and has a coolant inlet. The inlet of the micro pump is connected to the outlet of the coolant storage chamber, and the outlet of the micro pump is connected to the cooling water path. The end of the cooling water path furthest from the micro pump is connected to a cooling chamber located on the inner side of the mold cavity. When cooling is required, the micro pump delivers the coolant from the coolant storage chamber to the cooling water path. The coolant then enters the cooling chamber through the cooling water path, rapidly and uniformly cooling the mold cavity to ensure rapid product shaping and uniform internal structure.

[0009] Furthermore, the heating component includes a heating chamber and a heating coil, with the heating coil disposed inside the heating chamber. When heating is required, the heating coil is energized and generates heat, which is transferred to the mold cavity through the heating chamber to heat the mold cavity. Moreover, the placement of the heating coil inside the heating chamber reduces heat loss, improves heating efficiency, and ensures that the mold cavity temperature quickly reaches the set value.

[0010] Furthermore, a detection chamber is provided on the inner wall of the mold cavity, and a temperature sensor is installed inside the detection chamber. The temperature sensor can sense and detect the temperature inside the mold cavity in real time and feed the detected temperature data back to the external control system. This allows the staff to adjust the working status of the heating and cooling components in a timely manner based on the temperature data, ensuring that the temperature of the mold cavity is always kept within the set range, improving the temperature control accuracy, and guaranteeing the product molding quality.

[0011] Furthermore, the molding die also includes a protective component, which includes a protective back plate and load-bearing reinforcing columns. The protective back plate is fixedly connected to the inside of the side reinforcing steel through several load-bearing reinforcing columns. The protective back plate, together with the side reinforcing steel located on the side of the molding die, can protect the entire molding die, prevent external debris from entering the mold and affecting product molding, and also prevent injury to external personnel during the mold's operation, thereby improving the safety and reliability of the mold.

[0012] Furthermore, the power supply device is equipped with a power supply socket; the power supply socket is used to connect an external power source to supply power to various electrical components such as the mold drive cylinder, demolding cylinder, micro pump, heating coil, and temperature sensor, ensuring that each component works normally.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the following effects can be achieved by setting a molding die for a hollow titanium alloy rotating body structure: 1. By setting a mold base moving assembly, this application utilizes the cooperation of the mold base moving track and the mold base moving slider to achieve precise and stable movement of the lower mold base and related components, effectively improving the accuracy and stability of the mold base movement, better meeting the forming requirements of high-precision hollow titanium alloy rotating body structures, and reducing dimensional deviations after part forming; 2. The mold base vibration damping assembly adopts a combination of damping damping columns and springs, which significantly improves the damping effect compared to the traditional single damping structure, effectively alleviating the vibration generated during mold operation, extending the service life of the mold, and avoiding the adverse effects of vibration on the forming quality of parts, reducing the generation of surface defects in parts; 3. The cooperation between the mold guide slider and the mold guide track in the mold cover guide assembly provides precise guidance for the movement of the upper mold cover, effectively avoiding the offset and shaking of the upper mold cover during mold closing, improving the mold closing accuracy, thereby improving the forming accuracy of the hollow titanium alloy rotating body structure and reducing the defect rate of parts; 4. The demolding air in the demolding auxiliary assembly... The cylinder and ejector block automatically push the part out of the mold after molding, eliminating the need for manual assistance, improving demolding efficiency, and avoiding potential damage to the part caused by manual demolding, thus reducing production and time costs. 5. The cooling assembly, through the coordinated operation of the coolant storage chamber, cooling water circuit, and micro-pump, along with the heating chamber and heating coil in the heating assembly, enables precise temperature control of the mold cavity, resulting in more uniform heating and higher cooling efficiency. This ensures the stability of the molding quality of the titanium alloy hollow rotating body structure, allowing the part to meet expected performance requirements. 6. The detection chamber and temperature sensor allow for real-time and accurate monitoring of temperature changes inside the mold cavity, facilitating timely adjustments to heating or cooling operations based on temperature variations. This provides strong support for the quality control of the molding of titanium alloy hollow rotating body structures, contributing to the production of high-quality parts. 7. The protective backplate and load-bearing reinforcing pillars in the protective assembly provide effective protection for the mold, reducing interference and damage from external factors, improving mold safety, reducing threats to operator safety, and enhancing mold reliability.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are shown. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Example 1

[0018] Please see Figure 1 as well as Figure 2 This embodiment provides a molding die for hollow titanium alloy rotating body structure. The die adopts a modular design and the components are stably connected, which can realize the precise forming, convenient demolding and efficient temperature control of hollow titanium alloy rotating body structure. The mold includes a base 1, a bearing seat 2, a demolding auxiliary component 3, a lower mold base 4, a mold base moving component 5, a mold base shock absorption component 6, a top plate 7, a power supply device 8, a drive cylinder 9, a connecting frame 10, an upper mold cover 11, side reinforcing steel 12, a mold cover guide component 13, a mold cavity 14, a cooling component 15, and a heating component 16. The support base 2 is positioned above the base 1 and supports the demolding auxiliary component 3 and the lower mold base 4. The demolding auxiliary component 3 is fixed above the support base 2 and assists in demolding after product molding. The lower mold base 4 is positioned above the demolding auxiliary component 3 and is the main support structure of the mold cavity 14. To facilitate the adjustment of the position of the lower mold base 4 and the loading and unloading operations, the lower part of the support base 2 and the base 1 are connected by a mold base moving component 5. At the same time, to reduce vibration during mold closing and molding processes and ensure product molding accuracy, mold base vibration damping components 6 are provided between the lower left and right sides of the lower mold base 4 and the top of the left and right sides of the support base 2. The top plate 7 is positioned above the molding die, serving as the mounting carrier for the power supply device 8 and the drive cylinder 9. Both the power supply device 8 and the drive cylinder 9 are located on top of the top plate 7. The power supply device 8 supplies power to the various electrical components of the die, while the drive cylinder 9 provides the power for mold closing and opening. The connecting frame 10 and the upper mold cover 11 are located at the bottom output end of the drive cylinder 9 and below the top plate 7. When the drive cylinder 9 is working, it can drive the connecting frame 10 and the upper mold cover 11 to move up and down synchronously. The side reinforcing steel 12 is fixedly installed on the left and right sides between the base 1 and the top plate 7, which can enhance the overall structural strength of the die and improve its load-bearing capacity. In addition, to ensure the accuracy of the upper mold cover 11 when moving up and down and to avoid deviation, a mold cover guide assembly 13 is provided between the left and right sides of the connecting frame 10 and the inner sidewall of the side reinforcing steel 12. A mold cavity 14 is provided above the lower mold base 4 corresponding to the upper mold cover 11. The shape of the mold cavity 14 is adapted to the shape of the hollow part of the titanium alloy rotating body structure, which is the molding space of the product. In order to meet the temperature requirements in the titanium alloy molding process, a cooling component 15 and a heating component 16 are respectively provided on the periphery of the mold cavity 14 and inside the upper mold cover 11. Through the coordinated work of the cooling component 15 and the heating component 16, the temperature of the mold cavity 14 can be precisely controlled. Example 2

[0019] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 as well as Figure 7This embodiment, based on embodiment 1, further defines the structures of the mold base moving assembly 5, the mold base vibration damping assembly 6, and the mold cover guiding assembly 13 to improve the stability and ease of operation of the mold. The mold base moving assembly 5 includes a mold base moving track 51 and a mold base moving slider 52. The mold base moving track 51 is set on the base 1, and the mold base moving slider 52 is connected to the bottom of the support seat 2, and the mold base moving slider 52 slides in cooperation with the mold base moving track 51. When it is necessary to adjust the position of the support seat 2 and the lower mold base 4, the operator can push the support seat 2 to make the mold base moving slider 52 slide along the mold base moving track 51, thereby driving the support seat 2 and the lower mold base 4 to move synchronously. The operation is convenient and the movement process is stable, which can avoid the positional displacement of the lower mold base 4 from affecting the subsequent mold closing accuracy. The mold base vibration damping assembly 6 includes a damping column 61 and a spring 62. The spring 62 is sleeved and installed around the damping column 61. The top and bottom of the damping column 61 are fixedly connected to the lower mold base 4 and the bearing seat 2 by nuts 63. Both the damping column 61 and the spring 62 are located between the bearing seat 2 and the lower mold base 4. When the mold is closed, the drive cylinder 9 drives the upper mold cover 11 to press down on the lower mold base 4. At this time, the damping column 61 and the spring 62 will be compressed under pressure, absorbing the vibration energy generated during the mold closing process. If the mold vibrates during the molding process, the damping column 61 and the spring 62 can also play a buffering and damping role, effectively reducing the impact of vibration on the product molding in the mold cavity 14 and ensuring the dimensional accuracy of the product. The mold cover guide assembly 13 includes a mold guide slider 131 and a mold guide rail 132. The mold guide rail 132 is disposed on the inner side wall of the side reinforcing steel 12. The mold guide slider 131 is connected to the connecting frame 10, and the mold guide slider 131 and the mold guide rail 132 are slidably engaged. When the drive cylinder 9 drives the connecting frame 10 and the upper mold cover 11 to move up and down, the mold guide slider 131 will slide synchronously along the mold guide rail 132. Through the cooperation of the mold guide slider 131 and the mold guide rail 132, the movement trajectory of the connecting frame 10 and the upper mold cover 11 can be limited, avoiding the upper mold cover 11 from shifting left and right during the movement, ensuring that the upper mold cover 11 and the lower mold base 4 are accurately closed, and reducing the product scrap rate caused by inaccurate mold closing. Example 3

[0020] Please see Figure 2 , Figure 5 as well as Figure 7Based on Example 1, this embodiment refines the structure of the demolding auxiliary component 3, cooling component 15, and heating component 16 to optimize the demolding effect and temperature control accuracy. The demolding auxiliary component 3 includes a demolding cylinder 31 and an ejector block 32 connected to the upper output end of the demolding cylinder 31. The size of the ejector block 32 is adapted to the bottom of the mold cavity 14, and the ejector block 32 can move up and down under the drive of the demolding cylinder 31. After the hollow titanium alloy rotating body structure is formed in the mold cavity 14, the drive cylinder 9 drives the upper mold cover 11 to move upward to open the mold. Then, the demolding cylinder 31 is activated, pushing the ejector block 32 upward. The ejector block 32 pushes the formed hollow titanium alloy rotating body structure, allowing the product to detach from the mold cavity 14, achieving convenient demolding and avoiding demolding difficulties or product damage caused by the product sticking to the mold cavity 14, thereby improving production efficiency and product qualification rate. The cooling assembly 15 includes a coolant storage chamber 151, a cooling water passage 152, and a micro pump 153. The coolant storage chamber 151 is used to store coolant, and a coolant inlet is provided on the coolant storage chamber 151 so that the operator can add coolant to the coolant storage chamber 151 through the coolant inlet. The input end of the micro pump 153 is connected to the output end of the coolant storage chamber 151, and the output end of the micro pump 153 is connected to the cooling water passage 152. The end of the cooling water passage 152 away from the micro pump 153 is connected to the cooling chamber 154 on the inner side of the outer periphery of the mold cavity 14. When cooling of the mold cavity 14 is required, the micro pump 153 is started, which delivers the coolant in the coolant storage chamber 151 to the cooling water channel 152. The coolant enters the cooling chamber 154 along the cooling water channel 152. The cooling chamber 154 is arranged around the mold cavity 14, which can make the coolant evenly wrap around the mold cavity 14, quickly remove the heat of the mold cavity 14, achieve uniform cooling of the mold, ensure rapid product shaping, and at the same time ensure uniform internal structure of the product and improve the mechanical properties of the product. The heating assembly 16 includes a heating chamber 161 and a heating coil 162. The heating chamber 161 is arranged around the periphery of the mold cavity 14 (located outside the cooling chamber 154), and the heating coil 162 is disposed inside the heating chamber 161 and is electrically connected to the power supply device 8. When the mold cavity 14 needs to be heated, the power supply device 8 supplies power to the heating coil 162. After being energized, the heating coil 162 generates heat, which is transferred to the mold cavity 14 through the heating chamber 161, thereby heating the mold cavity 14. The arrangement of the heating chamber 161 can reduce heat loss, improve heating efficiency, and enable the temperature of the mold cavity 14 to quickly reach the set value required for titanium alloy molding. Furthermore, the heating coil 162 surrounding the mold cavity 14 can ensure uniform heating of the mold cavity 14 and avoid local overheating or underheating, which would affect the product molding quality. Example 4

[0021] Please see Figure 1 , Figure 3 as well as Figure 4 This embodiment, based on embodiment 1, adds a detection component and a protection component 18, and supplements the structure of the power supply device 8 to improve the safety and intelligence of the mold. A detection cavity 17 is also provided on the inner wall of the mold cavity 14. A temperature sensor 171 is installed inside the detection cavity 17 and is electrically connected to an external control system. The temperature sensor 171 can sense and detect the internal temperature of the mold cavity 14 in real time and transmit the detected temperature data to the external control system. Operators can monitor the temperature of the mold cavity 14 in real time through the external control system. When the temperature is lower than the set value, the heating component 16 can be activated to start heating; when the temperature is higher than the set value, the cooling component 15 is activated to cool, achieving precise temperature control of the mold cavity 14 and further ensuring the product molding quality. The forming mold also includes a protective component 18, which includes a protective back plate 181 and load-bearing reinforcing columns 182. The protective back plate 181 is made of high-strength steel plate, and the load-bearing reinforcing columns 182 are metal cylindrical structures. The protective back plate 181 is fixedly connected to the inside of the side reinforcing steel 12 through several load-bearing reinforcing columns 182. The protective back plate 181, together with the side reinforcing steel 12 located on the side of the forming mold, can form a protective structure surrounding the mold. On the one hand, it can prevent external debris (such as dust and debris) from entering the mold, avoiding debris from affecting product molding or damaging the mold components; on the other hand, it can prevent burns to external personnel during mold operation (such as when the heating component 16 is heating), or prevent damage to the mold from external collisions, thereby improving the safety and service life of the mold. The power supply device 8 is equipped with a power supply socket 19, which is electrically connected to various electrical components such as the mold drive cylinder 9, demolding cylinder 31, micro pump 153, heating coil 162, and temperature sensor 171. Operators can connect an external power source through the power supply socket 19 to provide stable power to each component, ensuring their normal operation. Simultaneously, the power supply device 8 is equipped with an overload protection module. When an electrical component experiences an overload, the overload protection module automatically cuts off the power supply to prevent damage and improve the safety of mold use.

[0022] The workflow of this invention is as follows: When using the titanium alloy rotating hollow part shaping mold, firstly, connect an external power source through the power supply socket 19 on the power supply device 8 to supply power to all electrical components such as the drive cylinder 9, demolding cylinder 31, micro pump 153, heating coil 162, and temperature sensor 171; check the connection status of each component to confirm that the mold base moving assembly 5 (mold base moving track 51, mold base moving slider 52) and the mold cover guiding assembly 13 (mold guide slider 131, mold guide track 132) slide smoothly, the mold base shock absorption assembly 6 (damping shock absorption column 61, spring 62, nut 63) is not loose, and the protective assembly 18 (protective back plate 181, load-bearing reinforcing column 182) is intact; Then push the support seat 2 to make the mold base moving slider 52 slide along the mold base moving track 51, and drive the lower mold base 4 to move out of the working area of ​​the mold body; clean the mold cavity 14 on the lower mold base 4 to remove internal impurities; put the titanium alloy raw material (such as titanium alloy billet or molten titanium alloy) into the mold cavity 14 according to the process requirements; push the support seat 2 in the opposite direction to make the lower mold base 4 return to the mold closing position corresponding to the upper mold cover 11; The heating assembly 16 is activated by an external control system. The power supply device 8 supplies power to the heating coil 162 in the heating chamber 161. The heating coil 162 generates heat, which is transferred to the mold cavity 14 through the heating chamber 161. The temperature sensor 171 in the detection chamber 17 on the inner side wall of the mold cavity 14 senses the internal temperature of the cavity in real time and feeds the data back to the external control system. When the temperature is lower than the set value required for titanium alloy molding, the system keeps the heating coil 162 working. When the temperature reaches the set value, the temperature sensor 171 triggers a signal, and the system controls the heating coil 162 to maintain a constant temperature, ensuring that the temperature of the mold cavity 14 is stable and meets the process requirements. The drive cylinder 9 at the top of the top plate 7 is activated. The output end of the drive cylinder 9 drives the connecting frame 10 and the upper mold cover 11 to move downward synchronously. During the movement, the mold guide sliders 131 on both sides of the connecting frame 10 slide along the mold guide track 132 on the inner wall of the side reinforcing steel 12 to ensure that the upper mold cover 11 moves down accurately along the fixed track. The upper mold cover 11 gradually approaches the lower mold base 4 and finally closes with the lower mold base 4. At the moment of mold closing, the mold base damping component 6 (damping damping column 61 and spring 62) under the lower mold base 4 is squeezed and contracted to absorb the impact force and vibration of mold closing and prevent the raw material in the mold cavity 14 from shifting due to vibration. The drive cylinder 9 continuously outputs pressure to make the upper mold cover 11 and the lower mold base 4 fit tightly together and apply molding pressure to the titanium alloy raw material in the mold cavity 14. Under the action of high temperature and pressure, the titanium alloy raw material gradually fits the inner wall of the mold cavity 14 to form the prototype of the hollow part of the rotating structure. After the titanium alloy raw material is formed in the mold cavity 14 for a preset time, the heating coil 162 is turned off by the external control system, and the cooling component 15 is started at the same time. The power supply device 8 supplies power to the micro pump 153, which draws out the coolant from the coolant storage cavity 151 and delivers it to the cooling water channel 152. The coolant flows along the cooling water channel 152 into the cooling cavity 154 on the outer side of the mold cavity 14, and flows around the mold cavity 14, quickly removing the heat from the mold cavity 14 and the internal molded part. The temperature sensor 171 continuously monitors the temperature of the mold cavity 14. When the temperature drops to the temperature required for the titanium alloy to solidify, it sends a signal to the external control system to turn off the micro pump 153 and stop cooling. The drive cylinder 9 is activated, which drives the connecting frame 10 and the upper mold cover 11 to move upward. The mold guide slider 131 moves upward synchronously along the mold guide rail 132. The upper mold cover 11 separates from the lower mold base 4, completing the mold opening. The demolding auxiliary component 3 is activated through the external control system. The power supply device 8 supplies power to the demolding cylinder 31. The output end of the demolding cylinder 31 pushes the ejector block 32 to move upward. The ejector block 32 extends into the bottom of the mold cavity 14 and pushes the formed titanium alloy rotating hollow part, so that the product is separated from the mold cavity 14, achieving non-destructive demolding. After demolding, the demolding cylinder 31 is controlled to drive the ejector block 32 to reset downwards and return to the initial position. The demolded titanium alloy rotating hollow part is then removed and the product quality is checked. The bearing seat 2 is pushed again to move the lower mold seat 4 out and clean the residual raw material debris or impurities in the mold cavity 14 to prepare for the next molding. After the lower mold seat 4 is reset, the power supply device 8 is turned off, completing a single workflow.

[0023] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
