Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to an input station applied to 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 of the existing precision molding machine, it takes a certain amount of time for the mold to enter the entrance sealing chamber. During this period, oxygen is easily filled into the entrance 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 entrance sealing chamber to maintain a stable low-oxygen cavity environment in the entrance 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 enters the molding machine, and further improve production capacity and product quality. Utility Model Content

[0026] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 7 The input station for a molding machine shown in the figure comprises a molding machine 1, wherein the molding machine 1 is provided with a main body opening 2, a supporting assembly 3 for placing a workpiece to be processed, a sealing chamber 4 located outside the main body opening 2, and a pushing assembly 5 movable relative to the sealing chamber 4, wherein the sealing chamber 4 is provided with a sealing cavity 41 communicating with the main body opening 2, a first sealing chamber 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 chamber opening 42, wherein one end of the pushing assembly 5 extends into the sealing cavity 41 and can drive the workpiece to move toward the main body opening 2;

[0028] When the support assembly 3 extends into the sealed cavity 41, the sealed cover assembly 43 moves away from the first sealed chamber opening 42, and the push assembly 5 drives the workpiece on the support assembly 3 to move to the inside of the main body opening 2. The utility model enhances the sealing performance of the molding machine by arranging a sealed chamber and a sealed cover assembly, optimizes the workpiece transfer path by using the support assembly and the push assembly, effectively solves the production problem caused by the poor sealing of the workpiece during the process of entering the molding machine, 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 high-precision optical components such as glass aspherical lenses, meeting the market's growing demand for high-quality optical products.

[0029] Specifically, by setting the first sealed chamber opening and the movable sealed cover assembly, it is ensured that the supporting assembly can complete the initial sealing in a relatively closed environment before carrying the workpiece to be processed into the main body of the molding machine, reducing the intervention of the outside air, and forming a transition stage in the process of the supporting assembly moving into the main body opening. The pushing assembly with one end extending into the sealed cavity not only enables the workpiece to move accurately between the sealed chamber and the main body opening, but also effectively reduces the damage to the sealing caused by the workpiece during the transfer process, ensuring the continuity and stability of the sealed environment during the dynamic process of the workpiece transfer.

[0030] Further, as a preferred embodiment of the present invention but not a limitation, the workpiece to be processed is first placed on the support assembly, and the support assembly supports the workpiece through the first sealed chamber opening and extends into the sealed cavity, and the first sealed chamber opening is blocked to reduce the entry of external oxygen into the sealed cavity. Once the workpiece completely enters the sealed cavity, the sealing cover assembly starts to move in a direction away from the first sealed chamber opening, and at the same time, the pushing assembly is started to push the workpiece toward the main body opening. The workpiece is sent to the inner side of the main body opening of the molding machine, ready for the subsequent hot pressing molding process.

[0031] 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.

[0032] like Figures 1 to 6 The shown input station for a molding machine, the support assembly 3 includes a support portion 31 for placing the workpiece to be processed, a step portion 32 connected to the support portion 31, and a first driving member 33 for driving the step portion 32 to approach or move away from the first sealed chamber opening 42, the outer diameter of the step portion 32 is larger than the outer diameter of the support portion 31, and the outer diameter of the first sealed chamber opening 42 is smaller than the outer diameter of the step portion 32. Further, as a preferred embodiment of the present invention but not a limitation, the support portion directly carries the workpiece to be processed, and the smaller outer diameter of the support portion relative to the first sealed chamber opening ensures that the support portion can be smoothly placed in the sealed cavity, and the large outer diameter of the step portion 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 opening of the first sealing chamber, and cooperate with the movement of the sealing cover assembly to achieve a fast and reliable sealing effect, effectively isolating the external environment, creating a stable, low-oxygen working environment for the molding process, improving the flexibility of operation and the reliability of sealing, and ensuring that the sealing state is maintained after the support portion moves with the workpiece to the sealing chamber, avoiding air leakage caused by manual operation or loose mechanical fit.

[0033] like Figures 3 to 7 The illustrated input station for the molding machine includes a sealing cover assembly 43, which includes a cover 431 that 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 for driving the cover 431 to approach or move away from the first sealing chamber opening 42. The outer diameter of the cover 431 is greater than the outer diameter of the first sealing chamber opening 42. Further, as a preferred embodiment of the present invention but not limited thereto, the outer diameter of the cover is greater than the outer diameter of the first sealing chamber opening, ensuring that the first sealing chamber opening can be completely covered and closed. 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. 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.

[0034] like Figures 1 to 7 In the input station for a molding machine shown in the figure, the sealed chamber 4 is provided with a second sealed chamber opening 44, the pushing assembly 5 includes a push rod 51 with one end passing through the second sealed chamber opening 44 to the sealed chamber 41, a push block 52 connected to the push rod 51, and a third driving member 53 connected to the push rod 51, and the push rod 51 is provided with a connecting portion 54 located outside the sealed chamber 41 and close to the second sealed chamber opening 44. Specifically, the design of the second sealed chamber opening ensures that during the operation of the push rod and the push block, external air will not penetrate into the sealed chamber through the access point of the pushing assembly, thereby maintaining the low oxygen environment of the sealed chamber, one end of the push rod passes through the second sealed chamber opening from the outside to the sealed chamber, and is used to drive the push block to push the workpiece on the supporting assembly, the push block is located inside the sealed chamber, and the workpiece is pushed, and the third driving member is connected to the push rod and provides driving force, so that the push rod reciprocates in the sealed chamber.

[0035] 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.

[0036] Optionally, in some embodiments, the third driving member may be an electric, pneumatic or hydraulic driving device.

[0037] Specifically, after the support assembly carries the workpiece into the sealed cavity, the sealed cover assembly moves away from the first sealed chamber opening, the third driving member starts and drives the push rod to move toward the main body opening, thereby driving the push block to contact the workpiece, and the push block pushes the workpiece along a predetermined path toward the inside of the main body opening of the molding machine. When the workpiece is pushed to the specified position, the third driving member moves in the opposite direction, causing the push rod and the push block to retract to the initial position, ready for pushing the next workpiece.

[0038] like Figures 5 to 7 The input station shown is applied to the molding machine, the main body opening 2 is provided with a sealing door 21 that can be closed or opened, the main body opening 2 is arranged opposite to the second sealing chamber opening 44, the push block 52 is arranged in a V-shape or an arc shape, and at least one guide groove 22 is arranged 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 into the main body of the molding machine, 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. The second sealing chamber opening of the sealing chamber is arranged opposite to the main body opening of the molding machine, so that the pushing component can push the workpiece from the sealing cavity to the inside of the main body opening in a straight line.

[0039] The main function of the guide groove is to guide the workpiece to smoothly enter the main body 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 push block adopts a V-shaped or arc-shaped design so that the push block can better adapt to its shape when pushing the workpiece, ensuring that the workpiece can move smoothly and accurately in a straight line and be pushed to the target position. Specifically, the V-shaped setting can better fit the contour of the workpiece due to its expanded contact edge, and 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] Specifically, when the support assembly carries the workpiece into the sealed cavity, the third driving member is activated to push the push rod and the V-shaped push block toward the main body opening. The V-shaped push block contacts the workpiece, and the workpiece is pushed to the main body opening along the direction of the guide groove. When the workpiece approaches the main body opening, the sealing door opens to allow the workpiece to enter. After the workpiece enters the main body opening, the sealing door quickly closes to restore the sealing state inside the molding machine. Subsequently, the molding machine performs the subsequent hot pressing molding process.

[0041] like Figures 1 to 7The input station shown is applied to the molding machine, 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 and movable up and down, a first driving member bracket 332 connected to the lifting assembly 331, and a first guide rail 333 connected to the first driving member bracket 332, the first driving member bracket 332 is provided with a first driving mechanism 3321, and the first driving member bracket 332 is slidably connected to the first guide rail 333 through the first driving mechanism 3321, so that the lifting assembly 331 drives the step portion 32 to approach or move away from the sealing chamber 4 in the horizontal direction. Further, as a preferred embodiment of the utility model but not limited thereto, the lifting assembly is connected to the step portion, and drives the step portion 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 provide a uniform and controllable rising or falling force to ensure that the workpiece maintains a correct posture during the transfer process and avoids damage or positioning deviation caused by vibration or tilt. The lifting assembly is connected to the step portion, and this design enables the step portion to move in the vertical direction. The lifting assembly is connected to the first drive member bracket, and through the action of the first drive mechanism, the first drive member bracket drives the lifting assembly to slide on the first guide rail, thereby achieving the lifting assembly in the horizontal direction. The flexibility and operability of the first drive member are increased, and the consistency and repeatability of each operation are ensured.

[0042] Optionally, in some embodiments, the lifting assembly is driven by electric, pneumatic or hydraulic means.

[0043] Optionally, in some embodiments, the first driving mechanism may be an electric, pneumatic or hydraulic driving device.

[0044] Specifically, after the workpiece is placed on the supporting part at one end close to the first guide rail, the first driving mechanism is started, and the first driving member bracket moves horizontally to the other end of the first guide rail, and the step portion is pushed upward by the jacking assembly, thereby driving the supporting part and the workpiece close to the sealed chamber. After the supporting part and the workpiece completely enter the sealed chamber, the jacking assembly stops working until the workpiece is processed. The sealing cover assembly is re-covered on the opening of the first sealed chamber, and the jacking assembly is reversed to pull the step portion downward by the jacking assembly, thereby driving the supporting part away from the sealed chamber, and the first driving member is reversed to drive the supporting part to move to one end close to the first guide rail.

[0045] like Figures 1 to 7In the input station for 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.

[0046] 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.

[0047] 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.

[0048] Optionally, in some embodiments, the lifting member is driven electrically, pneumatically or hydraulically.

[0049] Specifically, when the supporting assembly carries the workpiece through the first sealed chamber opening and enters the sealed chamber, the workpiece 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 in the sealed chamber. After the workpiece is processed, the second driving member operates in the reverse direction, 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 chamber.

[0050] like Figures 5 to 7The third driving member 53 shown in the input station for the molding machine includes a pushing portion 531 connected to the push rod 51 and a second guide rail 532 connected to the pushing portion 531. The moving direction of the push block 52 is parallel to the extending direction of the second guide rail 532. The pushing portion 531 is slidably connected to the second guide rail 532 so that the push rod 51 drives the push block 52 to approach or move away from the main body opening 2. Further, as a preferred embodiment of the utility model but not limited thereto, the pushing portion is directly connected to the push rod and is responsible for transmitting power to the push rod so that it can drive the push block to move, thereby ensuring the linear motion path of the push block in the process of pushing the workpiece into the main body 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 pushing portion to move along a predetermined path. Specifically, the extending direction of the second guide rail is parallel to the moving direction of the push block, ensuring the smooth and accurate movement of the push block, thereby realizing the movement of the push rod and the push block to approach or move away from the main body opening.

[0051] Alternatively, in some embodiments, the pushing portion may be a hydraulically, pneumatically or electrically driven device.

[0052] Specifically, after the support assembly carries the workpiece into the sealed chamber, the third driving member is activated, and the push portion begins to slide along the second guide rail, thereby pushing the push rod to move toward the main body opening, and the push block moves with the push rod. When the push block contacts the workpiece, the push block pushes the workpiece to the inside of the main body opening of the molding machine. After the workpiece is pushed into place, the third driving member can be reversed to make the push portion slide in the opposite direction along the second guide rail, thereby pulling the push rod and the push block back to prepare for the push of the next workpiece.

[0053] like Figures 3 to 7 In the input station used in the molding machine shown, a gap 47 is provided between the push block 52 and the inner wall of the sealing cavity 41, and the end surface of the support portion 31 is flush with the inner wall of the sealing cavity 41, or the depth of the support 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 push block and the inner wall of the sealing cavity allows the push block to move freely in the sealing cavity, while avoiding friction or collision between the push block and the inner wall of the sealing cavity, thereby extending the service life of the sealing cavity.

[0054] 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 less than the gap, so that the push block will not collide with the supporting part during movement, ensuring the normal movement of the workpiece and the predetermined route.

[0055] like Figures 1 to 7In the shown input station applied to a molding machine, the sealing chamber 4 is provided with at least one air pipe 46 extending into the sealing cavity 41 .

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] like Figures 1 to 7 As shown, the implementation method of Example 1 is as follows:

The first driving member bracket 332 is slidably connected to the first guide rail 333 through the first driving mechanism 3321, so that the lifting assembly 331 drives the step portion 32 to approach or move away from the sealing chamber 4 in the horizontal direction. The lifting assembly 331 adopts an electric drive mode. The first driving mechanism 3321 is an electric driving device.

[0069] 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 for limiting the position.

[0070] The lifting member 4321 is electrically driven.

[0071] The third driving member 53 includes a pushing portion 531 connected to the push rod 51, and a second guide rail 532 connected to the pushing portion 531. The moving direction of the push block 52 is parallel to the extension direction of the second guide rail 532. The pushing portion 531 is slidably connected to the second guide rail 532 so that the push rod 51 drives the push block 52 to approach or move away from the main body opening 2.

[0072] The pushing portion 531 is an electrically driven device.

[0073] A gap 47 is defined between the push block 52 and the inner wall of the sealing cavity 41 , and the upper end surface of the supporting portion 31 is flush with the bottom inner wall of the sealing cavity 41 .

[0074] The sealing chamber 4 is provided with three air pipes 46 extending into the sealing cavity 41 .

[0075] One of the air pipes 46 is used as an exhaust pipe to help quickly extract the air or excess gas in the sealed cavity 41, speed up the vacuuming process, and ensure that a low-oxygen or even oxygen-free stable environment is maintained in the sealed cavity 41. The two air pipes 46 for conveying nitrogen can be directly connected to the inner cavity of the cover body 431 to convey nitrogen to reduce the oxygen content in the inner cavity of the cover body 431.

[0076] After the workpiece is placed on the supporting part 31 at one end close to the first guide rail 333, the first driving mechanism 3321 is started, and the first driving member bracket 332 moves horizontally to the other end of the first guide rail 333, and pushes the step part 32 upward through the lifting assembly 331, thereby driving the supporting part 31 and the workpiece close to the sealing chamber 4. After the supporting part 32 and the workpiece completely enter the sealing chamber 41, the lifting assembly 331 stops working. After the supporting assembly 3 carries the workpiece into the sealing chamber 41, the workpiece is located in the inner cavity of the cover body 431, and the second driving member 432 is started. The lifting member 4321 starts working and drives the cover body 431 to move away from the first sealing chamber opening 42. The third driving member 53 is started and moves toward the main body opening 2 by driving the push rod 51, thereby driving the V-shaped push block 52 to contact the workpiece, and the V-shaped push block 52 pushes the workpiece to move along the predetermined path toward the inside of the main body opening 2 of the molding machine. When the workpiece is pushed to the designated position, when the workpiece approaches the main body opening 2, the sealing door 21 opens to allow the workpiece to enter. After the workpiece enters the main body opening 2, the sealing door 21 quickly closes, and the third driving member 53 moves in the opposite direction, so that the push rod 51 and the V-shaped push block 52 return to the initial position to prepare for the next workpiece to be pushed. The second driving member 432 operates in the reverse direction, and the lifting member 4321 pushes the cover body 431 close to the first sealing chamber opening 42 until the cover body 431 completely covers the first sealing chamber opening 42, thereby achieving the closure of the sealing chamber 41.

[0077] When the sealing cover assembly 5 is re-closed on the first sealing chamber opening 42, the lifting assembly 331 is operated in reverse, and the step portion 32 is pulled downward by the lifting assembly 331, thereby driving the supporting portion 31 away from the sealing chamber 4, and the first driving mechanism 3321 is operated in reverse, driving the supporting portion 31 to move to one end close to the first guide rail 333.

[0078] The utility model enhances the sealing performance of the molding machine by providing a sealing chamber 4 and a sealing cover assembly 43, and optimizes the workpiece transfer path by using a supporting assembly 3 and a pushing assembly 5, thereby effectively solving the production problem caused by poor sealing of the workpiece during the process of entering the molding machine, and can significantly improve production efficiency, reduce the consumption of auxiliary materials such as nitrogen, and reduce production costs, while ensuring the processing quality of high-precision optical components such as glass aspherical lenses, and meeting the market's growing demand for high-quality optical products.

[0079] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
