Description

Technical Field

[0001] The invention relates to the technical field of glass piston compression molding, in particular to a semi-solid compression molding device and process for a glass piston with threads. Background Art

[0002] Glass has significant advantages as a material for manufacturing glass instruments. It exhibits excellent chemical stability and can resist the erosion of various chemical reagents, ensuring the accuracy of experimental results. At the same time, the high transparency of glass makes the experimental process clearly visible, easy to operate and observe. Its high temperature resistance is suitable for a variety of heating or cooling experimental needs. In the production of glass instruments, it is often necessary to use a compression molding device. The compression molding device is an integrated molding processing equipment with wide applicability. It mainly uses a hydraulic press and a mold to apply pressure to the material to shape it.

[0003] At present, the molding devices on the market have low automation levels and low production efficiency. When glass products have threads, they are prone to thread discontinuity. When molding special-shaped or strip-shaped glass products, after the lump of glass raw materials enters the mold, due to the large difference between the appearance of the lump of 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. The manual placement method is inefficient and cannot meet production requirements. It is also prone to quality problems such as steam drums. Summary of the invention

[0004] The object of the present invention is to provide a semi-solid compression molding device and process for a glass piston with threads, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a semi-solid molding device for a glass piston with a thread, comprising a molding base, a control console installed on the molding base, a bracket installed on the console, a hydraulic device installed on the bracket, a molding assembly installed on the molding base, a vibration ring rotatably installed on the console, a feeding device installed on the molding base, a vibration motor installed at the bottom end of the feeding device, the output shaft of the vibration motor meshes with the vibration ring through a gear for transmission, the molding assembly is connected to the hydraulic device, an annular conveying device is installed in the molding base, a molding motor is installed in the molding base, the output shaft of the molding motor is connected to the molding assembly, a sliding motor is installed on the molding base, a sliding gear is installed on the output shaft of the sliding motor, and the sliding gear meshes with the molding assembly for transmission.

[0006] The control system is installed in the console, and the control system is used to control the entire molding device. The feeding device is used to melt the glass piston raw material into a semi-solid state, and feed the semi-solid mass raw material to the molding component. 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 semi-solid mass raw material to the pre-forming vibration device.

[0007] The molding assembly includes a lower mold assembly, a demolding cylinder, an upper mold assembly, a pre-forming vibration device, a lower mold assembly and a limit plate. The lower mold assembly is rotatably mounted on the molding base, the molding motor output shaft is connected to the lower mold assembly, the demolding cylinder is installed in the molding base, the upper mold assembly is connected to the hydraulic device, the limit plate is connected to the control console, the upper mold assembly is slidably connected to the limit plate, a positioning assembly is installed on the upper mold assembly, and the pre-forming vibration device is installed in the molding base.

[0008] The preforming vibration device includes a sliding rod, a sliding ring and a top block. The sliding rod is installed in the molding base, the sliding ring is rotatably connected to the molding base, the top block is installed in the 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 the side of the preforming module close to the top block, a T-shaped groove is provided on the preforming module running through from top to bottom, a hemispherical groove is provided on the top of the preforming module, a clamping assembly is installed at the bottom end of the preforming module, an electric heating assembly is provided in the preforming module, and the top of the vibration sliding column is an inclined surface.

[0009] The control system first uses the electric heating component to preheat the preforming module to reach the production temperature to prevent the raw material from cooling prematurely. The lump of semi-solid raw material falls into the hemispherical groove of the preforming module. The control system turns on the vibration motor, and the output shaft of the vibration motor drives the vibration ring to rotate. The gear teeth at the bottom of the vibration ring rotate and press the top inclined surface of the vibration slide column. The vibration slide column is compressed and drives the preforming module to slide down. The preforming module overcomes the elastic force of the vibration spring and slides downward along the sliding rod through the vertical strip groove. When the gear teeth at the bottom of the vibration ring disengage from the contact with the vibration slide column as it rotates, the preforming module bounces up and resets under the elastic force of the vibration spring, and so on, causing the preforming module to vibrate up and down, so that the lump of semi-solid raw material gradually vibrates in the hemispherical groove and falls to the T-slot, and gradually deforms into a T-shape under the action of vibration, and finally passes through the T-slot and falls into the pressing module, thereby realizing the pre-deformation of the lump of raw material, so that the raw material can be formed faster and with higher quality during the 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 plate is installed on the T-shaped sliding rod, a clamping spring is installed between the clamping plate and the sliding limit block, the clamping rotating rod is slidably connected to the T-shaped slider, a vertical strip groove is provided on the preforming module, and the sliding rod passes through the strip groove.

[0011] The preforming module slides forward and backward on the sliding rod through the strip groove. At the same time, since the strip groove is located in a vertical position, the preforming module can also slide up and down on the sliding rod.

[0012] The upper pressure membrane assembly includes a lower pressure plate, which is installed at the bottom of the hydraulic device. A connecting column is installed at the bottom of the lower pressure plate. The connecting column is slidably connected to the limit plate, and an upper pressure module is installed at the bottom of the connecting column.

[0013] After the raw material deformed into a T shape falls into the mold groove of the lower pressure module, the control system starts the molding motor, and the molding motor rotates a preset angle to rotate the lower pressure module and align it with the upper pressure module. Then the control system starts the hydraulic device, and the hydraulic device drives the upper pressure module and the positioning assembly to move downward through the lower pressure plate. The fixed clamp on the positioning assembly is gradually pressed down until the slot on the fixed clamp contacts the molding connecting rod. As the fixed clamp falls, the molding connecting rod gradually deflects and is locked by the slot and cannot rotate. The lower pressure module at one end of the molding connecting rod deflects together, thereby realizing the correction and fixation of the lower pressure module.

[0014] At the same time, after the expansion piece contacts with the molding column, it overcomes the elastic force of the expansion spring and moves under the action of pressure. The expansion piece moves and drives the vacuum tube to slide in the tube through the expansion connecting rod. When the upper pressure module and the lower pressure module are closed, the vacuum tube just stretches and docks with the vacuum hole. Then, the control system turns on the air pump, and the air pump draws air to the vacuum hole through the vacuum tube, so that a pressure difference is formed between the mold grooves in the lower pressure module and the upper pressure module and the outside world, and the raw material near the vacuum 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, thereby 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 allow the coolant to flow through the cooling channels in the upper pressure module and the lower pressure module to preliminarily cool the formed glass piston. After the preliminary cooling is completed, the control system controls the hydraulic device to recover.

[0015] The positioning assembly includes a spring telescopic rod and a telescopic connecting rod. The spring telescopic rod is installed at the bottom of the lower pressure plate. A fixed clamp is installed at the bottom of the spring telescopic rod. A tube is installed on the fixed clamp. A vacuum tube is slidably installed in the tube. The vacuum tube passes through the fixed clamp and is installed with an air pipe slider. The air pipe slider is installed with a telescopic piece through the rotation of the telescopic connecting rod. A telescopic spring is installed between the telescopic piece and the fixed clamp. The vacuum tube is externally connected to an air pump.

[0016] The control system starts the molding motor, and the molding motor drives the pressing module to rotate and align with the preforming module. Then the control system starts the demoulding cylinder, and the output shaft of the demoulding cylinder drives the bottom support block to slide upward. The bottom support block drives the first demoulding module and the second demoulding module to rise through the gravity detection component. The first demoulding module and the second demoulding module push the formed glass piston out of the pressing module. Then, the output shaft of the demoulding cylinder extends further, driving the first demoulding module and the second demoulding module to push the glass piston to the clamping piece. Under the pressure of the glass piston, the clamping piece overcomes the elastic force of the clamping spring and slides to both sides. After the glass piston completely enters between the clamping pieces, the clamping piece clamps the glass piston in the opposite direction under the action of the clamping spring. The control system starts the sliding motor, and the output shaft of the sliding motor drives the sliding ring to rotate through the sliding gear, and the sliding ring drives the preforming module to rotate through the vibrating sliding column. Since the preforming module is constrained by the sliding rod, the preforming module converts the rotation into sliding on the sliding rod, and the preforming module drives the clamping assembly to slide until the clamping slider and the top block are squeezed, and the clamping slider is compressed and contracted, thereby driving the clamping rotating rod to rotate, and the clamping rotating rod rotates and drives the T-shaped sliding rod to slide on the sliding limit block, and the T-shaped sliding rod drives the clamping piece to overcome the elastic force of the clamping spring to slide, so that the clamping piece releases the clamping of the glass piston. After the glass piston loses the clamping force, it falls to the annular conveying device, and the annular conveying device conveys the glass piston to the external collection device, and the previous steps are repeated in a cycle to complete the molding of the entire glass piston.

[0017] 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 molding motor output shaft, a lower pressing module is installed at one end of the molding connecting rod, a first stripping module and a second stripping module are slidably installed in the lower pressing module, a gravity detection assembly is installed at the bottom end of the first stripping module and the second stripping module, a ground support block is installed at the bottom end of the gravity detection assembly, an upper pressing module and a lower pressing module are provided with air exhaust holes, and cooling channels are provided in the upper pressing module and the lower pressing module; the gravity detection assembly 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, and the top of the telescopic column is respectively connected to the first stripping module and the second stripping module.

[0018] The first stripping module and the second stripping module fit tightly with the pressing module. During the feeding process, the demoulding cylinder drives the gravity detection component to lift up through the bottom support block, and the gravity detection component drives the first stripping module and the second stripping module to lift up. When the pre-deformed semi-solid raw material falls into the pressing module, it will cause an impact on the first stripping module and the second stripping module, and drive the first stripping module and the second stripping module to press down the gravity detection component. After the gravity detection component is compressed, the upper telescopic column overcomes the elastic force of the pressure spring and slides down. 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 demoulding cylinder to reset, and starts the molding motor, drives the pressing module to rotate and enter the molding process to prevent the semi-solid raw material from being retained and the temperature from dropping. The control system can also determine whether the feeding weight of the feeding device is accurate by analyzing the strength of the electrical signal.

[0019] A semi-solid compression molding process for a glass piston with a thread comprises the following steps: S1, the feeding device heats the raw material to a semi-solid state and conveys it to the molding component; S2, pre-deforming the semi-solid raw material by using a molded component; S3, driving the molding assembly to mold the semi-solid raw material through a hydraulic device; S4, cooling and shaping the formed glass piston by using a molding component; S5, completes autonomous demoulding through molded components, and cooperates with the ring conveyor device to achieve fully automatic unloading.

[0020] Compared with the prior art, the beneficial effect achieved by the present invention is as follows: the present invention utilizes a vibration ring to make the preforming module vibrate up and down, so that the lump of 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 action of vibration, thereby realizing the pre-deformation of the lump of raw material, so that the raw material can be molded more quickly and with higher quality during the molding process, and the raw material can be prevented from overflowing the mold during molding.

[0021] The glass piston is mass-produced by using multiple lower and upper pressing modules for simultaneous molding. The positioning assembly is used to correct and fix the lower pressing module, effectively preventing the lower and upper pressing modules from moving out of alignment and causing deformation of the finished glass piston, making the molding process more stable.

[0022] While positioning, the positioning component simultaneously drives the air pump to connect with the air pump hole. The air pump pumps air to the air pump hole through the air pump, so that the mold grooves in the lower pressure module and the upper pressure module form an air pressure difference with the outside world. The raw materials near the air pump hole fill the threads at the bottom of the mold groove more quickly. Under the action of the air pressure difference, the raw materials at the threads flow more quickly, improving the quality of thread forming. The glass piston is cooled and formed quickly and stably by using a water cooling cycle.

[0023] The demoulding cylinder is used to drive the first demoulding module and the second demoulding module to complete the demoulding. At the same time, the glass piston is quickly clamped by the clamping assembly, and the sliding ring is used to drive the clamping assembly to move, so that the glass piston is automatically disengaged and finally falls onto the annular conveying device, realizing full automation from demoulding to unloading.

[0024] The impact force of the pre-deformed raw material is converted into an electrical signal by using the gravity detection component. When the control system receives the electrical signal, it immediately rotates the pressing module and enters the molding process to prevent the semi-solid raw material from being retained and the temperature from dropping. The control system can also determine whether the feeding weight of the feeding device is accurate by analyzing the strength of the electrical signal. BRIEF DESCRIPTION OF THE DRAWINGS

The preforming module 624 overcomes the elastic force of the vibration spring 629 and passes through the vertical strip groove along the sliding rod 6 23 slides downward, and when the gears at the bottom of the vibration ring 11 are disengaged from the contact with the vibration slide column 6211 as they rotate, the preforming module 624 bounces back and returns to its original position under the elastic force of the vibration spring 629, and repeats this process, causing the preforming module 624 to vibrate up and down, thereby causing the mass of semi-solid raw material to gradually vibrate in the hemispherical groove 626 and fall into the T-slot 625, and gradually deform into a T-shape under the action of the vibration, and finally pass through the T-slot 625 and fall into the pressing module 651, thereby achieving pre-deformation of the mass of raw material, allowing the raw material to be formed more quickly and with higher quality during the molding process.

[0040] After the raw material deformed into a T shape falls into the mold groove of the lower pressing module 651, the control system starts the molding motor 7, and the molding motor 7 rotates a preset angle to rotate the lower pressing module 651 and align it with the upper pressing module 633. Then the control system starts the hydraulic device 5, and the hydraulic device 5 drives the upper pressing module 633 and the positioning assembly 61 to move downward through the lower pressing plate 631. The fixed clamp 618 on the positioning assembly 61 is gradually pressed down until the groove on the fixed clamp 618 contacts the molding connecting rod 652. As the fixed clamp 618 falls, the molding connecting rod 652 gradually deflects and is locked by the groove and cannot rotate. The lower pressing module 651 at one end of the molding connecting rod 652 deflects together, thereby realizing the correction and fixation of the lower pressing module 651.

[0041] The control system starts the molding motor 7, and the molding motor 7 drives the pressing module 651 to rotate and align with the preforming module 624. Then the control system starts the demoulding cylinder 66. The output shaft of the demoulding cylinder 66 drives the bottom support block 657 to slide upward. The bottom support block 657 drives the first demoulding module 654 and the second demoulding module 655 to rise through the gravity detection component. The first demoulding module 654 and the second demoulding module 655 push the formed glass piston out of the pressing module 651. Then, the output shaft of the demoulding cylinder 66 extends further, driving the first demoulding module 654 and the second demoulding module 655 to push the glass piston to the clamping piece 627. Under the pressure of the glass piston, the clamping piece 627 overcomes the elastic force of the clamping spring 6213 and slides to both sides. After the glass piston completely enters between the clamping pieces 627, the clamping piece 627 clamps the glass piston in the opposite direction under the action of the clamping spring 6213. The control system turns on the sliding motor 8, and 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 vibrating sliding column 6211. Since the preforming module 624 is constrained 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 assembly to slide until the clamping slider 6215 is squeezed with the top block 622, and 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 slide bar 6216 to slide on the sliding limit block 6212, the T-shaped slide bar 6216 drives the clamping piece 627 to slide to overcome 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 to the annular conveying device 2, and the annular conveying device 2 conveys the glass piston to the external collection device, and the previous steps are repeated in a cycle to complete the molding of the entire glass piston.

[0042] At the same time, after the expansion piece 615 contacts the molded column 653, it overcomes the elastic force of the expansion spring 614 and moves under the action of pressure. The expansion piece 615 moves and drives the air pumping tube 612 to slide in the tube 611 through the expansion link 616. When the upper pressure module 633 and the lower pressure module 651 are closed, the air pumping tube 612 just extends and docks with the air pumping hole 656. After that, the control system turns on the air pump, and the air pump pumps air to the air pumping hole 656 through the air pumping tube 612, so that the lower pressure module 651 and the upper pressure module 633 are closed. 3 forms an air pressure difference with the outside world, and the raw material near the air extraction hole 656 fills the thread at the bottom of the mold groove more quickly. Under the action of the air pressure difference, the raw material at the thread flows more quickly, thereby improving the quality of thread forming. Afterwards, the air pump is turned off. After the glass piston is molded, the control system turns on the water pump to allow the coolant to flow through the cooling channels in the upper pressure module 633 and the lower pressure module 651 to preliminarily cool the formed glass piston. After the preliminarily cooling is completed, the control system controls the hydraulic device 5 to recover it.
