Description

Technical Field

[0001] The present invention relates to the technical field of glass piston molding, and specifically relates to a semi-solid molding device and process for a threaded glass piston. Background Art

[0002] As a material for manufacturing glass instruments, glass has significant advantages. It exhibits excellent chemical stability, can resist the erosion of various chemical reagents, and ensures the accuracy of experimental results. At the same time, the high transparency of glass makes the experimental process clearly visible, facilitating operation and observation. Its high temperature resistance is suitable for various heating or cooling experimental requirements. In the production of glass instruments, a molding device is often required. The molding device is an integrated molding processing equipment with wide applicability, mainly by cooperating a hydraulic press with a mold to apply pressure to the material for shaping.

[0003] Currently, the molding devices on the market have a low level of automation and low production efficiency. When there are threads on glass products, situations such as discontinuous threads are likely to occur. When molding special-shaped or strip-shaped glass products, after the agglomerated glass raw materials enter the mold, due to the large difference between the appearance of the agglomerated raw materials and the finished product, direct molding not only has a slow molding speed, but also easily causes the raw materials to overflow during the extrusion process. And the method of manual placement has low efficiency, cannot meet production requirements, and is also prone to quality problems such as air bubbles. Summary of the Invention

[0004] The purpose of the present invention is to provide a semi-solid molding device and process for a threaded glass piston to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A semi-solid molding device for a threaded glass piston, including a molding base platform, a control console is installed on the molding base platform, a bracket is installed on the control console, a hydraulic device is installed on the bracket, a molding component is installed on the molding base platform, a vibration ring is rotatably installed on the control console, a feeding device is installed on the molding base platform, a vibration motor is installed at the bottom of the feeding device, and the output shaft of the vibration motor is meshed and driven with the vibration ring through a gear. The molding component is connected to the hydraulic device. An annular conveying device is installed inside the molding base platform, a molding motor is installed inside the molding base platform, the output shaft of the molding motor is connected to the molding component, a sliding motor is installed on the molding base platform, a sliding gear is installed on the output shaft of the sliding motor, and the sliding gear is meshed and driven with the molding component.

[0006] A control system is installed inside the console. The control system is used to control the entire compression molding device. The feeding device is used to melt the glass piston raw material into a semi-solid state and feed the agglomerated semi-solid raw material to the compression molding assembly. First, various production parameters are preset through the console. The feeding device is used to melt the glass piston raw material into a semi-solid state and feed the agglomerated semi-solid raw material to the preforming vibration device.

[0007] The compression molding assembly includes a lower compression mold assembly, a demolding cylinder, an upper compression mold assembly, a preforming vibration device, a lower compression mold assembly, and a limit plate. The lower compression mold assembly is rotatably installed on the compression molding base. The output shaft of the compression molding motor is connected to the lower compression mold assembly. The demolding cylinder is installed inside the compression molding base. The upper compression mold assembly is connected to the hydraulic device. The limit plate is connected to the console. The upper compression mold assembly is slidably connected to the limit plate. A positioning assembly is installed on the upper compression mold assembly. The preforming vibration device is installed inside the compression molding base.

[0008] The preforming vibration device includes a sliding rod, a sliding ring, and a top block. The sliding rod is installed inside the compression molding base. The sliding ring is rotatably connected to the compression molding base. The top block is installed inside the compression molding base. A preforming module is slidably installed on the sliding rod. A vibration sliding rod is slidably installed on the preforming module. A sliding sleeve is installed at the bottom end of the vibration sliding rod. A vibration spring is installed between the sliding sleeve and the preforming module. The sliding sleeve is slidably connected to the sliding rod. A vibration sliding column is installed on one side of the preforming module close to the top block. A T-shaped groove is provided on the preforming module and runs through it vertically. A hemispherical groove is provided at the top end of the preforming module. A clamping assembly is installed at the bottom end of the preforming module. An electric heating assembly is provided inside the preforming module. The top end of the vibration sliding column is beveled.

[0009] The control system first preheats the preforming module using the electric heating assembly to make it reach the production temperature, preventing the raw material from cooling prematurely. The agglomerated semi-solid raw material falls into the hemispherical groove of the preforming module. The control system turns on the vibration motor. The output shaft of the vibration motor drives the vibration ring to rotate. The teeth at the bottom of the vibration ring rotate and press the inclined surface at the top end of the vibration sliding column. The vibration sliding column is pressed and drives the preforming module to slide down. The preforming module overcomes the elastic force of the vibration spring and slides down along the sliding rod through the vertical strip groove. When the teeth at the bottom of the vibration ring rotate away from the contact with the vibration sliding column, the preforming module bounces back to its original position under the elastic force of the vibration spring. This process repeats, causing the preforming module to vibrate up and down, so that the agglomerated semi-solid raw material gradually vibrates and falls into the T-shaped groove in the hemispherical groove, and gradually deforms into a T shape under the vibration, and finally passes through the T-shaped groove and falls into the lower compression module, thus realizing the pre-deformation of the agglomerated raw material and making the raw material form more quickly and with higher quality during the compression molding process.

[0010] The clamping assembly includes a clamping slider, a sliding limit block and a clamping rotating rod. The clamping slider is slidably installed at the bottom end of the preforming module. The clamping rotating rod is rotatably installed at the bottom end of the preforming module. The clamping rotating rod is movably connected to the clamping slider. The sliding limit block is installed at the bottom end of the preforming module. A T-shaped sliding rod is slidably installed on the sliding limit block. A clamping piece is installed on the T-shaped sliding rod. A clamping spring is installed between the clamping piece and the sliding limit block. The clamping rotating rod is slidably connected to the T-shaped slider. A vertical strip-shaped groove is provided on the preforming module. The sliding rod penetrates through the strip-shaped groove.

[0011] The preforming module slides back and forth on the sliding rod through the strip-shaped groove. At the same time, due to the vertical position of the strip-shaped groove, the preforming module can also slide up and down on the sliding rod.

[0012] The upper pressing film assembly includes a lower pressing plate. The lower pressing plate is installed at the bottom end of the hydraulic device. A connecting column is installed at the bottom end of the lower pressing plate. The connecting column is slidably connected to the limiting plate. An upper pressing module is installed at the bottom end of the connecting column.

[0013] After the raw material deformed into a T shape falls into the mold groove of the lower pressing module, the control system turns on the molding press motor. The molding press motor rotates a preset angle to make the lower pressing module rotate and align with the upper pressing module. Then the control system turns on the hydraulic device. The hydraulic device drives the upper pressing module and the positioning assembly to move down through the lower pressing plate. The fixed chucks on the positioning assembly are gradually pressed down until the card slots on the fixed chucks contact the molding press connecting rod. As the fixed chucks fall, the molding press connecting rod gradually deflects and is locked by the card slots and cannot rotate. The lower pressing module at one end of the molding press connecting rod deflects together, so as to realize the deviation correction and fixation of the lower pressing module.

[0014] At the same time, after the telescopic piece contacts the molding press column, it moves under pressure to overcome the elastic force of the telescopic spring. The telescopic piece moves and drives the air extraction hard tube to slide in the tube through the telescopic connecting rod. When the upper pressing module and the lower pressing module are closed, the air extraction hard tube just elongates and docks with the air extraction hole. Then, the control system turns on the air pump. The air pump extracts air from the air extraction hole through the air extraction hard tube, so that an air pressure difference is formed between the mold grooves in the upper pressing module and the lower pressing module and the outside world. The raw material near the air extraction hole fills the bottom thread of the mold groove more quickly. Under the action of the air pressure difference, the raw material at the thread flows more quickly, improving the quality of thread forming. Then, the air pump is turned off. After the glass piston is molded, the control system turns on the water pump to make the coolant flow through the cooling holes in the upper pressing module and the lower pressing module to preliminarily cool the molded glass piston. After the preliminary cooling is completed, the control system controls the hydraulic device to retract.

[0015] The positioning assembly includes a spring telescopic rod and a telescopic connecting rod. The spring telescopic rod is installed at the bottom end of the lower pressing plate. A fixed chuck is installed at the bottom end of the spring telescopic rod. A tube is installed on the fixed chuck. A suction hard tube is slidably installed in the tube. The suction hard tube penetrates through the fixed chuck and is installed with an air tube slider. The air tube slider is rotationally installed with a telescopic piece through the telescopic connecting rod. A telescopic spring is installed between the telescopic piece and the fixed chuck. The suction hard tube is externally connected to an air pump.

[0016] The control system turns on the molding motor. The molding motor drives the lower pressing module to rotate and align with the preforming module. Then, the control system starts the demolding cylinder. The output shaft of the demolding cylinder drives the bottom support block to slide upward. The bottom support block drives the first demolding module and the second demolding module to rise through the gravity detection component. The first demolding module and the second demolding module push out the formed glass piston from the lower pressing module. Then, the output shaft of the demolding cylinder further extends, driving the first demolding module and the second demolding module to push the glass piston to the clamping piece. Under the extrusion of the glass piston, the clamping piece overcomes the elastic force of the clamping spring and slides open to both sides. After the glass piston completely enters between the clamping pieces, the clamping piece clamps the glass piston in the reverse direction under the action of the clamping spring.

[0017] The control system turns on the sliding motor. The output shaft of the sliding motor drives the sliding ring to rotate through the sliding gear. The sliding ring drives the preforming module to rotate through the vibrating sliding column. Since the preforming module is restricted by the sliding rod, the preforming module converts the rotation into sliding on the sliding rod. The preforming module drives the clamping assembly to slide until the clamping slider generates extrusion with the top block. The clamping slider is compressed and contracted, thereby driving the clamping rotating rod to rotate. The clamping rotating rod rotates and drives the T-shaped sliding rod to slide on the sliding limit block. The T-shaped sliding rod drives the clamping piece to slide against the elastic force of the clamping spring, so that the clamping piece releases the clamping of the glass piston. After the glass piston loses the clamping force, it falls onto the annular conveying device. The annular conveying device conveys the glass piston to the external collecting device, and the previous steps are repeated cyclically, thus completing the molding of the entire glass piston.

[0018] The lower pressing die assembly includes a molding column. A molding connecting rod is installed on the molding column. The molding column is installed on the output shaft of the molding motor. One end of the molding connecting rod is installed with a lower pressing module. The first demolding module and the second demolding module are slidably installed in the lower pressing module. Gravity detection components are installed at the bottom ends of the first demolding module and the second demolding module. A bottom support block is installed at the bottom end of the gravity detection component. Air suction holes are provided on both the upper pressing module and the lower pressing module. Cooling channels are provided in the upper pressing module and the lower pressing module. The gravity detection component includes a sliding shell. A bottom support block is installed at the bottom end of the sliding shell. An upper telescopic column is slidably installed in the sliding shell. A pressure spring is installed between the upper telescopic column and the sliding shell. A pressure contact is installed at the bottom end of the upper telescopic column. A pressure sensor is installed in the sliding shell. The top ends of the upper telescopic columns are respectively connected to the first demolding module and the second demolding module.

[0019] The first demolding module and the second demolding module are closely attached to the downward pressing module. During the feeding process, the demolding cylinder drives the gravity detection component to lift through the bottom support block, and the gravity detection component drives the first demolding module and the second demolding module to lift. When the pre-deformed semi-solid raw material falls into the downward pressing module, it will impact the first demolding module and the second demolding module, and drive the first demolding module and the second demolding module to press down the gravity detection component. After the gravity detection component is pressed, the upper telescopic column slides down against the elastic force of the pressure spring, and the upper telescopic column drives the pressure contact to squeeze the pressure sensor. The pressure sensor converts the pressure into an electrical signal and transmits it to the control system. After receiving the electrical signal, the control system controls the demolding cylinder to reset and turns on the molding motor to drive the downward pressing module to rotate and enter the molding process, preventing the semi-solid raw material from staying and the temperature from dropping. By analyzing the strength of the electrical signal, the control system can also determine whether the feeding weight of the feeding device is accurate.

[0020] A semi-solid molding process for a threaded glass piston includes the following steps:

[0021] S1. The feeding device heats the raw material to a semi-solid state and transports it to the molding assembly;

[0022] S2. The molding assembly is used to pre-deform the semi-solid raw material first;

[0023] S3. The molding assembly is driven by a hydraulic device to perform molding on the semi-solid raw material;

[0024] S4. The molding assembly is used to cool and shape the formed glass piston;

[0025] S5. The molding assembly completes self-demolding and cooperates with the annular conveying device to achieve full-automatic blanking.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention uses a vibration ring to make the pre-forming module vibrate up and down, so that the agglomerated semi-solid raw material gradually vibrates and falls into the T-shaped groove in the hemispherical groove, and gradually deforms into a T-shape under the vibration action, thereby realizing the pre-deformation of the agglomerated raw material, making the raw material form more quickly and with high quality during the molding process, and preventing the raw material from overflowing the mold during molding.

[0027] Multiple downward pressing modules and upward pressing modules are used for molding simultaneously, realizing the batch production of glass pistons. And the positioning component is used to correct and fix the downward pressing module, effectively preventing the downward pressing module and the upward pressing module from misaligning, resulting in deformation of the finished glass piston, and making the molding process more stable.

[0028] While positioning, the positioning component synchronously drives the air extraction hard pipe to dock with the air extraction hole. The air pump extracts air from the air extraction hole through the air extraction hard pipe, creating an air pressure difference between the mold grooves in the lower pressing module and the upper pressing module and the outside world. The raw materials near the air extraction hole are filled into the threaded part at the bottom of the mold groove more quickly. Under the action of the air pressure difference, the raw materials at the threaded part flow more quickly, improving the quality of thread forming. By using the water cooling circulation cooling method, the glass piston is quickly and stably cooled and shaped.

[0029] The demolding cylinder is used to drive the first demolding module and the second demolding module to complete demolding. At the same time, the clamping component is used to quickly clamp the glass piston, and the sliding ring is used to drive the clamping component to move, realizing the automatic separation of the glass piston and finally falling onto the annular conveying device, achieving full automation from demolding to blanking.

[0030] The gravity detection component is used to convert the impact force of the pre-deformed raw materials into an electrical signal. When the control system receives the electrical signal, it immediately rotates the lower pressing module and enters the molding process to prevent the semi-solid raw materials from staying and the temperature from dropping. By analyzing the strength of the electrical signal, the control system can also judge whether the feeding weight of the feeding device is accurate. Brief Description of the Drawings

[0054] A semi-solid molding process for a threaded glass piston includes the following steps:

[0055] S1. The feeding device 3 heats the raw material to a semi-solid state and conveys it to the pressing die assembly 6;

[0056] S2. The pressing die assembly 6 is used to pre-deform the semi-solid raw material first;

[0057] S3. The pressing die assembly 6 is driven by the hydraulic device 5 to perform semi-solid molding on the semi-solid raw material;

[0058] S4. The pressing die assembly 6 is used to cool and shape the formed glass piston;

[0059] S5. Autonomous demolding is completed through the molding component 6, and full-automatic blanking is achieved in cooperation with the annular conveying device 2.

[0060] The working principle of the present invention: First, various production parameters are preset through the control console 4. The feeding device 3 is used to melt the glass piston raw material into a semi-solid state and feed the agglomerated semi-solid raw material to the preforming vibration device 62.

[0061] The control system first preheats the preforming module 624 using the electric heating component to make it reach the production temperature to prevent the raw material from cooling in advance. The agglomerated semi-solid raw material falls into the hemispherical groove 626 of the preforming module 624. The control system turns on the vibration motor 10. The output shaft of the vibration motor 10 drives the vibration ring 11 to rotate. The teeth at the bottom of the vibration ring 11 rotate and press the inclined surface at the top of the vibration slide column 6211. The vibration slide column 6211 is pressed and drives the preforming module 624 to slide down. The preforming module 624 overcomes the elastic force of the vibration spring 629 and slides down along the sliding rod 623 through the vertical strip groove. When the teeth at the bottom of the vibration ring 11 rotate away from the contact with the vibration slide column 6211, the preforming module 624 rebounds and resets under the elastic force of the vibration spring 629. This process is repeated, causing the preforming module 624 to vibrate up and down, so that the agglomerated semi-solid raw material gradually vibrates and falls into the T-shaped groove 625 in the hemispherical groove 626, and gradually deforms into a T-shape under the vibration, and finally passes through the T-shaped groove 625 and falls into the lower pressing module 651, thereby realizing the pre-deformation of the agglomerated raw material and making the raw material form more quickly and with high quality during the molding process.

[0062] After the raw material deformed into a T-shape falls into the mold groove of the lower pressing module 651, the control system turns on the molding motor 7. The molding motor 7 rotates a preset angle to make the lower pressing module 651 rotate and align with the upper pressing module 633. Then the control system turns on the hydraulic device 5. The hydraulic device 5 drives the upper pressing module 633 and the positioning component 61 to move down through the lower pressing disk 631. The fixed chuck 618 on the positioning component 61 is gradually pressed down until the slot on the fixed chuck 618 contacts the molding connecting rod 652. As the fixed chuck 618 drops, the molding connecting rod 652 gradually deflects and is locked by the slot and cannot rotate. The lower pressing module 651 at one end of the molding connecting rod 652 deflects together, thereby realizing the deviation correction and fixation of the lower pressing module 651.

[0063] The control system activates the molding motor 7. The molding motor 7 drives the downward pressing module 651 to rotate and align with the preforming module 624. Then, the control system starts the demolding cylinder 66. The output shaft of the demolding cylinder 66 drives the bottom support block 657 to slide upward. The bottom support block 657 drives the first demolding module 654 and the second demolding module 655 to rise through the gravity detection component. The first demolding module 654 and the second demolding module 655 push out the formed glass piston from the downward pressing module 651. Then, the output shaft of the demolding cylinder 66 further extends, driving the first demolding module 654 and the second demolding module 655 to push the glass piston to the clamping piece 627. Under the extrusion of the glass piston, the clamping piece 627 slides open to both sides against the elastic force of the clamping spring 6213. After the glass piston completely enters between the clamping pieces 627, the clamping piece 627 clamps the glass piston in the reverse direction under the action of the clamping spring 6213;

[0064] The control system activates the sliding motor 8. The output shaft of the sliding motor 8 drives the sliding ring 621 to rotate through the sliding gear 81. The sliding ring 621 drives the preforming module 624 to rotate through the vibration sliding column 6211. Since the preforming module 624 is restricted by the sliding rod 623, the preforming module 624 converts the rotation into sliding on the sliding rod 623. The preforming module 624 drives the clamping component to slide until the clamping slider 6215 is squeezed by the top block 622. The clamping slider 6215 is compressed and contracted, thereby driving the clamping rotating rod 6214 to rotate. The clamping rotating rod 6214 rotates and drives the T-shaped sliding rod 6216 to slide on the sliding limit block 6212. The T-shaped sliding rod 6216 drives the clamping piece 627 to slide against the elastic force of the clamping spring 6213, so that the clamping piece 627 releases the clamping of the glass piston. After the glass piston loses the clamping force, it falls onto the annular conveying device 2. The annular conveying device 2 conveys the glass piston to the external collection device, and the previous steps are repeated cyclically, thus completing the molding of the entire glass piston.

[0065] Meanwhile, after the telescopic piece 615 contacts the molding post 653, it moves under pressure, overcoming the elastic force of the telescopic spring 614. The telescopic piece 615 moves and drives the air extraction rigid tube 612 to slide within the tube barrel 611 through the telescopic connecting rod 616. When the upper pressing module 633 and the lower pressing module 651 are closed, the air extraction rigid tube 612 just extends and docks with the air extraction hole 656. After that, the control system turns on the air pump, and the air pump extracts air from the air extraction hole 656 through the air extraction rigid tube 612, creating an air pressure difference between the mold cavities in the lower pressing module 651 and the upper pressing module 633 and the outside world. The raw material near the air extraction hole 656 fills the thread at the bottom of the mold cavity more quickly. Under the action of the air pressure difference, the raw material at the thread flows more quickly, improving the quality of thread forming. After that, the air pump is turned off. After the glass piston is molded, the control system turns on the water pump, allowing the cooling liquid to flow through the cooling channels in the upper pressing module 633 and the lower pressing module 651 to preliminarily cool the formed glass piston. After the preliminary cooling is completed, the control system controls the hydraulic device 5 to retract.
