Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to a material discharging component used for molding machines. Background Art

[0002] In the fields of car lenses, mobile phone lenses, small monitor lenses, sports DV lenses, laser collimators, etc., high-precision glass aspheric lenses are mainly used. With the development of science and technology, the demand for glass aspheric lenses in these fields is also growing. Precision molding machine is a kind of glass product hot pressing molding equipment, which is currently widely used in the production of consumer electronic products, optical products and automotive products. Glass aspheric lenses are mainly manufactured by molding technology. In the molding production process, the molding process parameters set in the molding equipment are pre-set and fixed. The molding equipment can only use a set of molding process parameters to mold lenses with multiple molds at the same time. Before the mold enters the sealed molding cavity of the molding equipment, it needs to be vacuumed to reduce the oxygen content in the mold and the oxygen content in the sealed molding cavity. Since the hot pressing molding of amorphous materials such as glass requires the material to be heated to a high temperature softening state before hot pressing molding can be carried out, in the high temperature oxygen environment, the structure, mold, workpiece, glass and other amorphous materials inside the equipment cavity will be oxidized, and the higher the oxygen content, the more serious the oxidation, which affects the product quality.

[0003] In the process of transporting the mold or workpiece, the existing precision molding machine takes a certain amount of time for the mold to leave the outlet sealing chamber. During this period, oxygen is easily filled into the outlet sealing chamber, which increases the oxygen content in the equipment cavity or the vacuum degree cannot be well controlled. Therefore, more nitrogen needs to be filled into the outlet sealing chamber to maintain a stable low-oxygen cavity environment in the outlet sealing chamber. This will increase production costs, affect the production capacity and quality of the lenses, and greatly reduce the service life of the equipment.

[0004] In view of the above shortcomings, the molding machine needs to be improved to solve the problem of poor sealing when the mold is separated from the molding machine and further improve the working performance of the equipment. Utility Model Content

[0027] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 8 The discharge assembly used in a molding machine shown comprises a molding machine 1, wherein the molding machine 1 is provided with a first discharge area 100, and a second discharge area 200, a supporting assembly 3 for placing workpieces and movable between the first discharge area 100 and the second discharge area 200, the first discharge area 100 is provided with a main body opening 2, a sealing bin 4 located outside the main body opening 2, a first conveying assembly 9 for pushing the workpiece from the inside of the main body opening 2 to the outside of the main body opening 2, and a first pushing assembly 5 movable relative to the sealing bin 4, the sealing bin 4 is provided with a sealing cavity 41 communicated with the main body opening 2, a first sealing bin opening 42 for the supporting assembly 3 to extend into the sealing cavity 41, and a sealing cover assembly 43 movably connected to the sealing cavity 41 and capable of covering or moving away from the first sealing bin opening 42, one end of the first pushing assembly 5 extends into the sealing cavity 41 and can drive the workpiece to move toward the first sealing bin opening 42;

[0029] The second discharge area 200 is provided with a movable second push component 6 and a second conveying component 8. When the support component 3 drives the workpiece to move to the second discharge area 200 and is located between the second push component 6 and the second conveying component 8, the second push component 6 drives the workpiece to move to the second conveying component 8. The utility model sets the first discharge area and the second discharge area. After the workpiece is moved out from the main body opening, it first enters the closed and controllable first discharge area. The sealing of the molding machine is enhanced by setting a sealing bin and a sealing cover body component. The first push component and the support component are used to optimize the workpiece transfer path, which effectively solves the production problem caused by the poor sealing of the workpiece during the process of leaving the molding machine. The workpiece is then transferred to the second discharge area for transportation through the support component, which effectively isolates the influence of the external environment on the molding machine and improves the continuity of the workpiece transfer. It can significantly improve production efficiency, reduce the consumption of auxiliary materials such as nitrogen, reduce production costs, and at the same time ensure the processing quality of the product, meeting the market's growing demand for high-quality products.

[0030] The sealed bin arranged in the first discharging area has a sealed cavity connected to the main body opening, and cooperates with the movably connected sealing cover body assembly to quickly close the first sealed bin opening when the supporting assembly carries the workpiece out, effectively isolating the external air, especially oxygen, from entering the sealed cavity, maintaining a low-oxygen environment in the sealed cavity, and reducing oxidation.

[0031] The first push assembly and the second push assembly work together to achieve smooth transfer of the workpiece between different areas. The first push assembly pushes the workpiece to the first sealed bin opening in a sealed environment, and then the second push assembly continues to push the workpiece to the second conveying assembly in the second discharge area.

[0032] The supporting assembly can carry the workpiece and move flexibly between the first discharge area and the second discharge area, which not only improves the continuity and efficiency of the production process, but also ensures the stability and safety of the workpiece during the entire transmission process.

[0033] Optionally, in some embodiments, the supporting assembly and the sealed chamber are abutted, and the first sealed chamber opening is closed. During the entire process, due to the good sealing of the sealed chamber, oxygen cannot enter, thereby reducing oxidation and protecting the workpiece and internal components of the molding machine.

[0034] First, in the first discharge area, the supporting assembly extends into the sealed cavity, and the sealing cover assembly starts to move in the direction away from the opening of the first sealed bin. The processed workpiece is sent to the outside of the main opening of the molding machine by the first conveying assembly, and the first pushing assembly is started to push the workpiece toward the opening of the first sealed bin. The workpiece is pushed onto the supporting assembly, and the first pushing assembly is reset. The sealing cover assembly moves again in the direction close to the opening of the first sealed bin and covers the opening of the first sealed bin. The supporting assembly supports the workpiece to pass through the opening of the first sealed bin to leave the sealed cavity and move to the second discharge area. When the supporting assembly drives the workpiece to move between the second pushing assembly and the second conveying assembly, the second pushing assembly is started and pushes the workpiece to move to the second conveying assembly.

[0035] like Figure 1 , Figure 2 and Figure 4 The discharge assembly used in the molding machine shown in the figure, the support assembly 3 includes a support part 31 for placing the workpiece to be processed, a step part 32 connected to the support part 31, and a first driving member 33 for driving the step part 32 to approach or move away from the first sealed chamber opening 42, the outer diameter of the step part 32 is larger than the outer diameter of the support part 31, and the outer diameter of the first sealed chamber opening 42 is smaller than the outer diameter of the step part 32. Further, as a preferred embodiment of the utility model but not a limitation, the support part directly carries the workpiece to be processed, and the smaller outer diameter of the support part relative to the first sealed chamber opening ensures that the support part can be smoothly placed in the sealed cavity, and the large outer diameter of the step part forms an effective sealing interface when in contact with the outer side of the sealed chamber to prevent air penetration. By controlling the movement of the step portion through the first driving member, the support assembly can be accurately moved toward or away from the opening of the first sealing chamber. The step portion can fit tightly against the sealing chamber and at the edge of the first sealing chamber opening, and cooperate with the movement of the sealing cover assembly to achieve a fast and reliable sealing effect, effectively isolating the external environment, and creating a stable, low-oxygen working environment for the inner cavity of the molding machine, thereby improving the flexibility of operation and the reliability of sealing, ensuring that the sealing state is maintained after the support portion moves to the sealing chamber, and avoiding air leakage caused by manual operation or loose mechanical fit.

[0036] like Figures 1 to 6The discharge assembly shown is applied to the molding machine, and a transition zone 300 is provided between the second conveying assembly 8 and the supporting assembly 3, and a connecting assembly 7 is slidably connected to the transition zone 300, and the connecting assembly 7 switches between being close to the transition zone 300 and being away from the transition zone 300, and the upper end surface height of the connecting assembly 7 is higher than or equal to the upper end surface height of the second conveying assembly 8. Further, as a preferred embodiment of the utility model but not a limitation, the setting of the transition zone enables the supporting assembly to have a smooth transition process when moving the workpiece from the first discharge zone to the second discharge zone, which helps to reduce the vibration and impact of the workpiece during the movement, thereby improving the quality and production efficiency of the workpiece. The sliding connection design of the connecting assembly on the transition zone can automatically connect the supporting assembly and the second conveying assembly. When the supporting assembly moves the workpiece to the transition zone, the connecting assembly can be quickly and accurately aligned with the supporting assembly and is ready to receive the workpiece. Since the height of the upper end surface of the connecting component is higher than or equal to the height of the upper end surface of the second conveying component, this ensures that the workpiece can be transferred from the supporting component to the connecting component and then to the second conveying component to maintain stability and continuity, reducing the possibility of operational errors such as collision between the workpiece and obstacles. The entire transition process has a high degree of automation, reducing the need for manual intervention, thereby improving production efficiency. At the same time, since the pause and waiting time of the workpiece during the movement process is reduced, production efficiency is further improved.

[0037] like Figures 2 to 6 The discharging assembly used in the molding machine shown in the figure, the connecting assembly 7 includes a sliding plate 71 for the workpiece to slide, and a sliding plate guide rail 72 connected to the sliding plate 71, the upper end surface height of the sliding plate 71 is higher than or equal to the upper end surface height of the supporting portion 31, and the sliding plate 71 is located on the upper side of the step portion 32 and close to the supporting portion 31. Further, as a preferred embodiment of the utility model but not limited, the sliding plate provides a smooth sliding surface for the workpiece, ensuring that the workpiece can move smoothly and continuously during the process of transferring from the supporting assembly to the second conveying assembly, reducing the damage to the workpiece caused by vibration and impact, and in addition, through the sliding plate guide rail, the moving direction and distance of the sliding plate can be accurately controlled, thereby ensuring that the workpiece can be accurately conveyed to the predetermined position. This precise control helps to improve production efficiency and workpiece quality. Furthermore, the upper end surface height of the sliding plate is designed to be higher than or equal to the upper end surface height of the supporting portion, ensuring that the workpiece can smoothly transition from the supporting assembly to the sliding plate during the transfer process, avoiding the workpiece from being stuck, colliding or tilting at the height difference. The sliding plate is located on the upper side of the step portion and close to the supporting portion. Such a layout makes the structure of the entire discharging assembly more compact, reduces the floor space, and also facilitates the operation and maintenance of workers.

[0038] like Figures 1 to 5In the discharge assembly shown for the molding machine, the width L of the upper end surface of the sliding plate 71 is greater than the horizontal distance between the step portion 32 and the second conveying assembly 8, the step portion 32 is provided with a sealing area 320 abutting against the sealing chamber 4, and the sliding plate 71 partially extends to the upper side of the sealing area 320. Further, as a preferred embodiment of the utility model but not a limitation, the width L of the upper end surface of the sliding plate is greater than the horizontal distance between the step portion and the second conveying assembly, the sliding plate can provide sufficient support area, ensuring that the workpiece can be fully supported and guided when it transitions from the supporting portion to the sliding plate, the sealing area is used to be in close contact with the sealing chamber, this structure not only strengthens the sealing effect of the sealing chamber during the movement of the supporting portion, but also effectively blocks oxygen from penetrating into the sealing cavity, the sliding plate partially extends to the upper side of the sealing area, and through the staggered setting, the limited space can be maximized.

[0039] like Figures 2 to 5 The discharge assembly used in the molding machine shown in the figure, the second discharge area 200 is also provided with a fixing part 60, a fixing part opening 600 located in the fixing part 60, the second pushing assembly 6 includes a second push rod 61 with one end passing through the fixing part opening 600, a second push block 62 connected to the second push rod 61, and a fourth driving member 63 connected to the second push rod 61, and the second push block 62 is arranged in a V shape or an arc shape. Further, as a preferred embodiment of the utility model but not limited, the fixing part can better fix and support the second push rod, and through the setting of the fixing part and the fixing part opening, the second push rod can stably pass through the fixing part opening and accurately push the second push block to the workpiece, ensuring the stability and accuracy of the workpiece during the pushing process, and reducing the damage or position displacement of the workpiece caused by improper pushing. The fourth driving member enables the second push rod and the second push block to move quickly, thereby improving the pushing efficiency of the workpiece, helping to speed up the production speed and improve the production efficiency. The second push block is arranged in a V shape or an arc shape, so that it can better adapt to workpieces of different sizes and shapes. Whether the workpiece is round, square or irregular in shape, the V-shaped or arc-shaped push block can effectively push it to the second conveyor assembly to ensure smooth transfer of the workpiece. Specifically, the V-shaped setting can better fit the contour of the workpiece due to its expanded contact edge, which is suitable for occasions that require more precise control; while the arc-shaped setting provides a larger contact area, which is conducive to dispersing pressure and protecting the more fragile workpiece surface.

[0040] Optionally, in some embodiments, the workpieces are arranged in a circular shape.

[0041] Optionally, in some embodiments, the fourth driving member adopts an electric, pneumatic or hydraulic power source.

[0042] Furthermore, the fixing portion is used to support the second guide rail 532 of the first pushing assembly.

[0043] like Figures 1 to 7 In the discharge assembly shown for the molding machine, the moving direction of the second push rod 61 is parallel to the conveying direction of the second conveying assembly 8, and the moving direction of the sliding plate 71 is perpendicular to the moving direction of the second push rod 61. Further, as a preferred embodiment of the utility model but not a limitation, by ensuring that the moving direction of the second push rod is parallel to the conveying direction of the second conveying assembly, when the workpiece is pushed from the second push block to the second conveying assembly, it can directly and smoothly enter the conveying path without additional steering or adjustment, and the parallel movement design reduces the pause and waiting time of the workpiece during the transfer process, so that the workpiece can enter the next process faster, thereby optimizing the entire workflow and improving production efficiency.

[0044] Specifically, on the horizontal plane, the moving direction of the sliding plate is perpendicular to the moving direction of the second push rod. Through the movement coordination of the second push rod and the sliding plate in different dimensions, and the movement of the supporting assembly in the longitudinal height direction, the misalignment between the components can save space and realize the seamless connection of the workpiece from the supporting part to the second conveying assembly. The whole process not only takes into account the stable transition of the workpiece, but also takes into account the continuity and efficiency of the production line.

[0045] like Figures 1 to 5 The discharge assembly used in the molding machine shown in the figure, the sealing cover assembly 43 comprises a cover 431 which can cover the first sealing chamber opening 42 and abut against the inner wall of the sealing chamber 41, and a second driving member 432 used to drive the cover 431 to approach or move away from the first sealing chamber opening 42, and the outer diameter of the cover 431 is larger than the outer diameter of the first sealing chamber opening 42. Further, as a preferred embodiment of the utility model but not limited thereto, the outer diameter of the cover is larger than the outer diameter of the first sealing chamber opening, ensuring that the first sealing chamber opening can be completely covered and closed, and the cover is in close contact with the inner wall of the sealing chamber, ensuring that good sealing can be maintained even when subjected to internal pressure changes or slight external disturbances, effectively preventing air circulation, especially oxygen infiltration, thereby reducing oxidation. The second driving member is used to drive the cover to approach or move away from the first sealing chamber opening, and the second driving member not only improves the automation of the operation, but also ensures the controllability and repeatability of the sealing process, so that each sealing action can achieve the expected effect, further enhancing the sealing performance of the entire molding process. Optionally, in some embodiments, the second driving member may be a pneumatic, electric or hydraulic driving device.

[0046] like Figures 1 to 5The discharge assembly used in the molding machine shown in the figure, the sealed bin 4 is provided with a second sealed bin opening 44, the first pushing assembly 5 includes a first push rod 51 with one end passing through the second sealed bin opening 44 to the sealed cavity 41, a first push block 52 connected to the first push rod 51, and a third driving member 53 connected to the first push rod 51, the first push rod 51 is provided with a connecting portion 54 located outside the sealed cavity 41 and close to the second sealed bin opening 44. Specifically, the design of the second sealed bin opening ensures that during the operation of the push rod and the push block, external air will not penetrate into through the access point of the first pushing assembly, thereby maintaining the low oxygen environment of the sealed cavity, one end of the first push rod passes through the second sealed bin opening from the outside to the sealed cavity, and is used to drive the first push block to push the workpiece on the supporting assembly, the first push block is located inside the sealed cavity, and the workpiece is pushed, the third driving member is connected to the first push rod and provides driving force, so that the first push rod reciprocates in the sealed cavity.

[0047] The connecting part can be connected to the sealing chamber by fasteners and seal the second sealing chamber opening. The connecting part has a certain guiding effect. Optionally, one end of the connecting part is attached to the outside of the sealing chamber, which can maintain the sealing and stability of the entire system while achieving efficient power transmission.

[0048] Optionally, in some embodiments, the third driving member may be an electric, pneumatic or hydraulic driving device.

[0049] Specifically, after the support assembly enters the sealed chamber, the sealed cover assembly moves away from the first sealed chamber opening, the third driving member starts and drives the first push rod to move toward the first sealed chamber opening, thereby driving the first push block to contact the workpiece, and the first push block pushes the workpiece to move along a predetermined path toward the first sealed chamber opening. When the workpiece is pushed to the specified position, the third driving member moves in the opposite direction, causing the first push rod and the first push block to retract to the initial position, preparing for the push of the next workpiece.

[0050] like Figure 8The discharging assembly used in the molding machine shown, the supporting assembly 3 is located at the lower side of the sealing chamber 4, the first driving member 33 includes a lifting assembly 331 connected to the step portion 32, a first driving member bracket 332 connected to the lifting assembly 331, and a first driving mechanism 3321 connected to the first driving member bracket 332, and the first driving mechanism 3321 drives the lifting assembly 331 to drive the step portion 32 close to or away from the sealing chamber 4. Further, as a preferred embodiment of the utility model but not limited to, the lifting assembly is connected to the step portion, and the step portion is driven to approach or move away from the sealing chamber through its lifting movement, so that the up and down movement of the step portion is more stable and accurate. The lifting assembly can rise or fall evenly and controllably, ensuring that the workpiece maintains the correct posture during the transfer process, avoiding damage or positioning deviation caused by vibration or tilt. By connecting the lifting assembly to the step portion, this design further realizes the movement of the step portion in the vertical direction. The lifting assembly is connected to the first driving member bracket, and the lifting assembly is driven to move in the vertical direction through the action of the first driving mechanism, thereby increasing the flexibility and operability of the first driving member and ensuring the consistency and repeatability of each operation.

[0051] Optionally, in some embodiments, the first driving mechanism may be an electric, pneumatic or hydraulic driving device.

[0052] Specifically, after the workpiece is placed on the supporting part, the sealing cover assembly is re-covered on the opening of the first sealing bin, the first driving mechanism is started, and the step portion is pulled downward by the lifting assembly, thereby driving the supporting part away from the sealing bin, until the supporting part moves to the second discharge area, the first driving mechanism stops working, and the workpiece is smoothly transferred to the second conveying assembly through the cooperation of the second pushing assembly and the connecting assembly. The first driving mechanism is started again, driving the lifting assembly to drive the step portion to move upward, thereby driving the supporting part close to the sealing bin. After the supporting part completely enters the sealing bin, the first driving mechanism stops working, and the sealing cover assembly moves away from the opening of the first sealing bin, until the workpiece is processed and placed on the supporting part, and the above operation is repeated.

[0053] like Figures 1 to 7In the discharge assembly used in the molding machine shown, the sealing chamber 4 is provided with a third sealing chamber opening arranged opposite to the first sealing chamber opening 42, and the second driving member 432 includes a lifting member 4321 with one end extending into the third sealing chamber opening to the sealing cavity 41 and connected to the cover body 431, and a limiting portion 4322 respectively connected to the lifting member 4321 and the sealing chamber 4. Further, as a preferred embodiment of the utility model but not a limitation, the third sealing chamber opening arranged opposite to the first sealing chamber opening provides an independent channel for the lifting driving assembly of the cover body, which not only maintains the overall sealing performance of the sealing chamber, but also ensures the flexibility and independence of the second driving member during operation, and reduces the possibility of mutual interference.

[0054] Specifically, the lifting member is connected to the cover body, and one end of the lifting member extends into the third sealed chamber opening directly into the sealed cavity, so that the opening and closing actions of the cover body are more precise and controllable. The direct drive mode of the lifting member improves the reaction speed and positioning accuracy, ensuring that the sealed cover body can quickly and tightly cover or leave the first sealed chamber opening, effectively isolating the external environment.

[0055] Optionally, in some embodiments, a limiter is provided between the lifting member and the sealing chamber, and the limiter may be located outside the sealing chamber or inside the sealing chamber. The limiter may set the travel range of the lifting member to prevent damage to the device or sealing failure caused by excessive lifting, while ensuring that a consistent sealing effect can be achieved in each operation.

[0056] Optionally, in some embodiments, the lifting member is driven electrically, pneumatically or hydraulically.

[0057] Specifically, after the supporting assembly enters the sealed cavity through the first sealed chamber opening, the supporting assembly is located in the inner cavity of the cover body, and the second driving member is activated. The lifting member starts to work and drives the cover body to move away from the first sealed chamber opening, so that the workpiece can move to the first sealed chamber opening in the sealed cavity. After the workpiece is completely placed on the supporting assembly, the second driving member operates in reverse, and the lifting member pushes the cover body to approach the first sealed chamber opening until the cover body completely covers the first sealed chamber opening, thereby achieving the closure of the sealed cavity, and the supporting assembly drives the workpiece away from the sealed chamber.

[0058] like Figures 1 to 7The discharging assembly shown for the molding machine, the third driving member 53 includes a first pushing portion 531 connected to the first push rod 51, and a second guide rail 532 connected to the first push portion 531, the moving direction of the first push block 52 is parallel to the extension direction of the second guide rail 532, and the first push portion 531 is slidably connected to the second guide rail 532, so that the first push rod 51 drives the first push block 52 to approach or move away from the first sealed chamber opening 42. Further, as a preferred embodiment of the utility model but not a limitation, the first pushing portion is directly connected to the first push rod and is responsible for transmitting power to the first push rod, so that it can drive the first push block to move, ensuring the linear motion path of the first push block in the process of pushing the workpiece to move to the first sealed chamber opening, and improving the stability of the motion and the positioning accuracy. The parallel moving direction design simplifies the mechanical structure, reduces the complexity, and is easy to maintain and operate. The second guide rail serves as a guide device, which can guide the first push portion to move along a predetermined path. Specifically, the extension direction of the second guide rail is parallel to the moving direction of the push block, ensuring the smooth and precise movement of the push block, thereby achieving the movement of the first push rod and the first push block approaching or moving away from the first sealing chamber opening.

[0059] Optionally, in some embodiments, the first pushing portion may be a hydraulically, pneumatically or electrically driven device.

[0060] Specifically, after the support assembly enters the sealed chamber, the third driving member is activated, and the push part starts to slide along the second guide rail, thereby pushing the first push rod to move toward the opening direction of the first sealed chamber, and the first push block moves with the first push rod. When the first push block contacts the workpiece, the first push block pushes the workpiece toward the opening direction of the first sealed chamber. After the workpiece is pushed to the support assembly, the third driving member can be reversely operated to make the first push part slide in the opposite direction along the second guide rail, thereby pulling the first push rod and the first push block back to prepare for pushing the next workpiece.

[0061] like Figure 5 In the discharge assembly used in the molding machine shown, a gap 47 is provided between the first push block 52 and the inner wall of the sealing cavity 41, and the end surface of the supporting portion 31 is flush with the inner wall of the sealing cavity 41, or the depth of the supporting portion 31 partially extending into the sealing cavity 41 is less than the distance of the gap 47. Further, as a preferred embodiment of the present utility model but not a limitation, the gap between the first push block and the inner wall of the sealing cavity allows the first push block to move freely in the sealing cavity, while avoiding friction or collision between the first push block and the inner wall of the sealing cavity, thereby extending the service life of the sealing cavity.

[0062] Specifically, after the supporting part extends upward into the sealed cavity, the upper end surface of the supporting part is flush with the bottom inner wall of the sealed cavity, or the upper end surface of the supporting part is higher than the bottom inner wall of the sealed cavity by a distance smaller than the gap, so that the first push block will not collide with the supporting part during movement, thereby ensuring the normal movement of the workpiece and the predetermined route.

[0063] like Figures 1 to 5 In the discharge assembly for a molding machine shown, the main body opening 2 is provided with a sealing door 21 that can be closed or opened, and at least one guide groove 22 is provided between the main body opening 2 and the first sealing chamber opening 42. Further, as a preferred embodiment of the utility model but not a limitation, the sealing door ensures that when the workpiece is pushed to the outside of the molding machine main body, the main body opening can be completely closed, thereby ensuring the stability and purity of the internal environment of the molding machine. Optionally, in some embodiments, the sealing door is made of wear-resistant and high-temperature resistant materials to adapt to various environments when the molding machine is working.

[0064] The main function of the guide groove is to guide the workpiece to move smoothly to the first sealing bin opening and ensure that the workpiece can move along a predetermined trajectory during the pushing process. Optionally, in some embodiments, the workpiece is circular in shape, and the guide groove includes a first guide groove 221 extending along the discharge direction of the first conveying component, and also includes a second guide groove 222 extending along the moving direction of the first push block. This arrangement ensures that the workpiece can move smoothly and accurately in a straight line direction from the discharge direction of the first conveying component to the direction of the first pushing component, and then move from the first pushing component and be pushed to the position of the first sealing bin opening.

[0065] Specifically, the first conveying assembly 9 includes a first conveying platform 91 for placing workpieces, a first conveying driving member 92 for driving the first conveying platform to move from the inner side of the main body opening 2 to the outer side of the main body opening 2, and a first conveying limiting end 93 arranged on the side close to the main body opening for limiting the first conveying platform to slide in the horizontal direction. When the workpiece needs to move outward from the inner side of the main body opening, the sealing door is opened, and the first conveying driving member pushes the first conveying platform to extend to a place close to the main body opening or directly to the inner side of the main body opening. After the workpiece is transferred to the first conveying platform along the first guide groove, the first conveying driving member drives the first conveying platform to move into the sealing cavity. When the workpiece is aligned with the first pushing block, the workpiece is pushed to the position of the first sealing chamber opening along the second guide groove through the first pushing assembly.

[0066] like Figures 1 to 8 In the discharge assembly for the molding machine shown, the sealed chamber 4 is provided with at least one air pipe 46 extending into the sealed cavity 41. Specifically, the air pipe is made of corrosion-resistant, high-temperature-resistant and wear-resistant materials to ensure that it is not easily damaged or leaked during long-term use.

[0067] Furthermore, as a preferred embodiment of the present invention but not a limitation, the air pipe can be used to deliver a specific gas, such as nitrogen, into the sealed cavity to further reduce the oxygen content and optimize the environmental conditions during the molding process. When necessary, it can also be used as an exhaust pipe to help quickly extract the air or excess gas in the sealed cavity, speed up the vacuuming process, and ensure that a low-oxygen or even oxygen-free stable environment is maintained in the sealed cavity. Of course, in this embodiment, an air pipe for delivering nitrogen into the sealed cavity is provided, and an air pipe for speeding up the vacuuming is also provided.

[0068] Optionally, in some embodiments, an air tube for accelerating vacuum extraction may be directly connected to the inner cavity of the cover body to extract the air in the cover body.

[0069] Optionally, in some embodiments, a gas pipe for conveying nitrogen may be directly connected to the inner cavity of the cover body to convey nitrogen to reduce the oxygen content in the inner cavity of the cover body.

[0070] Optionally, in some embodiments, the first conveying component also includes a first cooling component located on the upper side of the first conveying platform, the first cooling component is connected to a cooling plate 95, and a first cooling drive 96 connected to the cooling plate, the cooling plate is provided with a plurality of cooling plate openings 951, and a cooling plate slot connected to the cooling plate openings, further, the cooling plate slot is connected to an air pipe 46, when the workpiece is transferred to the first conveying platform along the first guide groove, the first cooling drive drives the cooling plate toward the workpiece, the air pipe outputs nitrogen, the nitrogen is transferred from the cooling plate slot to the cooling plate opening to quickly cool the workpiece surface, and at the same time reduce the oxygen content in the sealing chamber, when the workpiece is pushed to the position of the first sealing chamber opening, the air pipe stops outputting nitrogen, and the first cooling drive drives the cooling plate to move away from the workpiece.
