Description

Technical Field

[0001] This invention relates to the field of ceramic wine bottle injection molding technology, and in particular to an automatic injection molding device for ceramic wine bottles. Background Technology

[0002] The molding quality of ceramic wine bottles directly affects their sealing performance, mechanical strength, and appearance. Slip casting, a crucial process determining the quality of the finished product, works by injecting fluid slurry into a mold cavity, where the mold absorbs water, causing particles to deposit and form the green body. However, relying solely on natural slurry absorption has significant drawbacks: slurry particles settle at the bottom under gravity, leading to uneven density and varying wall thickness in the green body, and trapped air is difficult to expel, easily forming air bubbles. To overcome these defects, centrifugal slip casting is widely used in the industry. This process drives the mold to rotate at high speed while the slurry is being injected, using centrifugal force to compact the slurry particles against the mold wall, significantly improving the density of the green body; simultaneously, centrifugal force causes air bubbles to migrate towards the center and burst, effectively eliminating porosity defects. Therefore, simultaneous slip casting and centrifugal casting has become the mainstream process in the automated production of ceramic wine bottles.

[0003] Existing automated grouting equipment typically employs a linear transmission mechanism connecting various process stations. The mold support seat follows the transmission mechanism through grouting, pouring, and other processes sequentially. At the grouting station, the grouting mechanism suspended above injects slurry into the mold, while a rotary drive device below engages with the mold support seat, causing the mold to rotate synchronously, achieving simultaneous centrifugal grouting. The existing equipment uses a separate design for the rotary drive device, located below the grouting station, while the mold support seat moves with the transmission mechanism. When the mold reaches its position, the two engage via a lifting mechanism and separate after grouting is complete. While this design ensures transmission flexibility, it has significant drawbacks under high-speed rotation conditions: during simultaneous centrifugal grouting, the mold support seat and rotary drive device maintain transmission solely through engagement pressure; they are not a rigid, integrated structure, resulting in mechanical gaps. Continuous slurry injection causes dynamic changes in the liquid level within the mold cavity, shifting the combined center of gravity of the mold and slurry. Simultaneously, the periodic centrifugal force fluctuations generated by centrifugal rotation create a slight phase difference between the mold support seat and the rotary drive device. This phase difference manifests as a slippage tendency due to asynchronous rotation between the two components. The frictional force generated by the bonding pressure attempts to suppress this slippage, resulting in alternating shear stress. Because the mold support and the rotary drive are in separate contact, a mechanical gap exists between them, preventing complete elimination of this shear stress. During rotation, the mold support experiences high-frequency, micro-amplitude shaking relative to the rotary drive. This shaking causes pulsation in the rotating flow field within the mold cavity, resulting in uneven centrifugal force distribution and periodic fluctuations in the thickness of the slurry adhering to the mold's inner wall. Simultaneously, the shaking disrupts the slurry flow, causing wave-like undulations on the slurry surface and entraining air bubbles. More seriously, the shaking leaves spiral-shaped texture marks on the preform surface, affecting the finished product's appearance quality. In existing technologies, some equipment attempts to suppress shaking by increasing the bonding pressure, but excessive pressure exacerbates wear on the contact surface and cannot fundamentally eliminate the inherent gaps in the separate structure. Other equipment uses rigid pin positioning, but this places excessively high demands on the mold support's positioning accuracy, and the gap between the pin and the pin hole also leads to the accumulation of small deviations.

[0004] In summary, existing automatic injection molding equipment for ceramic wine bottles has significant shortcomings in terms of rotational stability of the separate drive structure. The phase difference and high-frequency shaking problems between the mold support and the rotary drive device have not been effectively solved. There is an urgent need for an injection molding equipment that can achieve rotational rigid constraint in order to improve the molding quality and production stability of ceramic wine bottles.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] like Figure 1-10As shown, this embodiment of the invention provides an automatic grouting device for ceramic wine bottles, including a main support frame 1. A transmission mechanism is provided on the main support frame 1, and a mold carrying assembly is installed on the transmission mechanism. A grouting mechanism is provided above the main support frame 1. The main support frame 1 is provided with a rotary drive mechanism and a lifting mechanism for driving the rotary drive mechanism to rise. The rotary drive mechanism is located directly below the grouting mechanism. The mold carrying assembly includes a mounting plate 2, and a rotating shaft 3 is rotatably mounted at the center of the mounting plate 2. A mold placement platform 4 is fixedly connected to the top of the rotating shaft 3, and a mold clamping assembly is provided on the mold placement platform 4. A driven engagement seat 5 is fixedly connected to the bottom of the rotating shaft 3. The rotary drive mechanism includes a rotary motor 6. The output shaft of the rotary motor 6 is driven and connected to the active engagement plate 7. The bottom of the driven engagement seat 5 is provided with a circular groove 501. A conical groove 502 is provided at the center of the bottom of the circular groove 501. Multiple wedge-shaped grooves 503 are distributed circumferentially on the side wall of the circular groove 501. The top of the active engagement plate 7 is fixedly connected to a frustum 8 that matches the circular groove 501. The top of the frustum 8 is fixedly connected to a centering conical column 9 that matches the conical groove 502. A sliding groove 801 corresponding to the wedge-shaped groove 503 is provided on the side wall of the frustum 8. A wedge-shaped locking block 10 that matches the wedge-shaped groove 503 is slidably connected in the sliding groove 801. A hydraulic drive mechanism for driving the wedge-shaped locking block 10 to slide is provided in the frustum 8.

[0021] Specifically, the upper surface of the active engagement plate 7 has a groove 701; the hydraulic drive mechanism includes a pressure cylinder 11 vertically fixedly installed in the groove 701, a pressure-bearing piston 12 slidably connected to the inner surface of the pressure cylinder 11, a pressure-bearing column 13 fixedly connected to the top of the pressure-bearing piston 12, the top of the pressure-bearing column 13 passing through the top of the pressure cylinder 11 and extending above the active engagement plate 7, a pressure-bearing block 14 fixedly connected to the top of the pressure-bearing column 13, a first return spring 15 connected between the top of the pressure-bearing piston 12 and the inner top of the pressure cylinder 11, a first hydraulic chamber 702 formed between the bottom surface of the pressure-bearing piston 12 and the inner bottom surface of the pressure cylinder 11, the first hydraulic chamber 702 being filled with hydraulic oil, and the sliding... An annular platform 16 is provided in the groove 801. A guide rod 17 slides through the annular platform 16. One end of the guide rod 17 is fixedly connected to the bottom of the wedge-shaped locking block 10. The other end of the guide rod 17 is fixedly connected to a push piston 18. A second return spring 19 is connected between the push piston 18 and the annular platform 16. The push piston 18 is slidably connected to the inner surface of the groove 801. A second hydraulic chamber 802 is formed between the push piston 18 and the bottom of the groove 801. A pressurizing chamber 703 is provided in the active engagement plate 7. The bottom of the pressurizing chamber 703 is connected to the first hydraulic chamber 702 through a first flow channel 704. The top of the pressurizing chamber 703 is connected to the second hydraulic chamber 802 through a second flow channel 705.

[0022] When the lifting mechanism drives the active engagement plate 7 to rise, the pressure block 14 first abuts against the bottom surface of the driven engagement seat 5 and moves downward under pressure. At this time, the pressure piston 12 compresses the first hydraulic chamber 702, and the hydraulic oil in it enters the pressurization chamber 703 through the first flow channel 704, and then is pressed into each of the second hydraulic chambers 802 through the second flow channel 705. Under the pressure of the hydraulic oil, the piston 18 is pushed to overcome the resistance of the second return spring 19 and drive the wedge-shaped locking block 10 to move radially outward along the slide groove 801, and finally embeds into the wedge-shaped groove 503 of the driven engagement seat 5.

[0023] Specifically, the active engagement plate 7 also has a pressure relief chamber 706. The top of the pressure relief chamber 706 is connected to the pressurization chamber 703 through the third flow channel 707, and the bottom of the pressure relief chamber 706 is connected to the first hydraulic chamber 702 through the fourth flow channel 708. A first electrically controlled on / off valve 20 is installed on the first flow channel 704, a second electrically controlled on / off valve 21 is installed on the third flow channel 707, and a third electrically controlled on / off valve 22 is installed on the fourth flow channel 708.

[0024] Specifically, the driven engagement seat 5 has multiple axial positioning grooves 504 circumferentially distributed on the side wall of the circular groove 501. The inner diameter of the axial positioning grooves 504 gradually decreases from the bottom to the top. The outer wall of the frustum 8 has axial positioning strips 23 corresponding to the axial positioning grooves 504, and the axial positioning strips 23 are clearance-fitted with the axial positioning grooves 504. During the process of the active engagement plate 7 rising with the lifting mechanism, the axial positioning strips 23 slide upward along the axial positioning grooves 504, thereby achieving preliminary pre-positioning in the circumferential direction, ensuring that the centering conical column 9 and the conical groove 502, and the wedge-shaped locking block 10 and the wedge-shaped groove 503 can be accurately aligned.

[0025] Specifically, the bottom of the axial positioning groove 504, the opening of the tapered groove 502, and the opening of the wedge-shaped groove 503 are all chamfered. The chamfered structure is used to guide the smooth tangential entry of the corresponding components.

[0026] Specifically, a base plate 24 is fixedly connected to the main support frame 1, and the lifting mechanism includes an electric telescopic rod 25 installed on the base plate 24. The piston rod of the electric telescopic rod 25 is connected to a lifting plate 26. A guide column 27 is vertically fixedly connected to the base plate 24. The lifting plate 26 is slidably sleeved on the guide column 27, and the rotary motor 6 is fixedly installed on the lifting plate 26.

[0027] Specifically, it also includes a signal processing unit. A pressure detection hole 901 is located at the center of the top surface of the centering conical column 9, and a pressure sensor 28 is embedded within the pressure detection hole 901. The signal processing unit includes a signal amplifier, an analog-to-digital converter, and a microcontroller. The output of the pressure sensor 28 is connected to the input of the signal amplifier, the output of the signal amplifier is connected to the input of the analog-to-digital converter, the output of the analog-to-digital converter is connected to the input of the microcontroller, and the output of the microcontroller is connected to the drive controller of the electric telescopic rod 25. Based on the contact pressure value fed back by the pressure sensor 28, the microcontroller can monitor the contact tightness between the active engagement plate 7 and the driven engagement seat 5 in real time, and adjust the upward displacement of the electric telescopic rod 25 accordingly to achieve closed-loop control.

[0028] Specifically, the transmission mechanism includes multiple sets of sprockets 29 rotatably mounted on the main support frame 1. The multiple sets of sprockets 29 are connected by a chain 30. A drive motor 31 that drives one sprocket 29 to rotate is mounted on the main support frame 1. Multiple mounting frames 32 are fixedly mounted on the chain 30. The mounting plate 2 is fixedly mounted on the mounting frame 32.

[0029] Specifically, an electrically controlled locking mechanism is provided between the mounting plate 2 and the mold placement platform 4. This mechanism includes an electromagnetic pin on the mounting plate 2 and a pin hole at the bottom of the mold placement platform 4. When the equipment is in transmission mode, the electromagnetic pin is driven by an electrical control signal to insert into the pin hole, thereby restricting the rotation of the shaft 3. When entering the grouting station, the electromagnetic pin retracts, releasing the lock on the shaft 3. In non-grouting station positions, this prevents the shaft 3 from rotating due to the inertia generated by the chain movement.

[0030] Specifically, the main support frame 1 is provided with a mounting bracket 33, and the grouting mechanism includes a grouting mounting seat 34 mounted on the mounting bracket 33. A grouting head 35 is mounted on the bottom of the grouting mounting seat 34, and a grouting pipe 36 connected to the grouting head 35 is mounted on the grouting mounting seat 34. A flow control valve is mounted on the grouting pipe 36.

[0031] Furthermore, in this example, the mold clamping assembly includes a first fixing plate 37 and a second fixing plate 38 symmetrically arranged on both sides of the mold placement platform 4. A fixed clamping plate 39 is fixedly connected to the side of the first fixing plate 37 near the second fixing plate 38. Mold limiting wheels 40 are provided on both sides of the fixed clamping plate 39. An adjusting screw 41 is threadedly connected to the second fixing plate 38. A movable clamping plate 42 is fixedly connected to the end of the adjusting screw 41 near the first fixing plate 37. A sliding rod 43 is slidably passed through the second fixing plate 38. The sliding rod 43 is arranged parallel to the adjusting screw 41. The end of the sliding rod 43 near the first fixing plate 37 is fixedly connected to the movable clamping plate 42. The mold on the mold placement platform 4 is clamped and fixed by the fixed clamping plate 39 and the movable clamping plate 42.

[0032] In actual operation, the installation frame carrying the mold is first transported to the grouting station via a transmission mechanism. At this time, the electromagnetic pin retracts to release the lock on the rotating shaft 3. The lifting mechanism starts, and the electric telescopic rod 25 drives the lifting plate 26, the rotary motor 6, and the active engagement plate 7 to move upward. During the ascent, the axial positioning bar 23 first enters the axial positioning groove 504 for circumferential alignment. Subsequently, the centering conical column 9 is inserted into the conical groove 502 to achieve axial centering. As the lifting mechanism continues to rise, the pressure block 14 contacts the bottom surface of the driven engagement seat 5 and is pressed into the pressure cylinder 11. The hydraulic oil in the first hydraulic chamber 702 is forced into the second hydraulic chamber 802, driving the wedge-shaped locking block 10 to extend outward and tightly embed into the wedge-shaped groove 503, thereby forming a multi-point rigid constraint structure from centering to radial locking between the active engagement plate 7 and the driven engagement seat 5. This equipment, through a mechanical and hydraulic linkage structure, eliminates the mechanical clearance of the separate transmission at high speeds, ensuring the stability of the grouting process.

[0033] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principles of this invention are further supplemented below with a specific application scenario.

[0034] First, the drive motor 31 drives the chain 30 of the transmission mechanism to circulate, transporting the mounting frame 32 containing the ceramic mold to the top of the grouting station. At this time, the microcontroller controls the electromagnetic pin to retract via an electrical control signal, releasing the rotation restriction on the mold placement platform 4. Subsequently, the controller instructs the electric telescopic rod 25 of the lifting mechanism to start, driving the lifting plate 26 to move the rotary motor 6 and the active engagement plate 7 vertically upward along the guide column 27. As the active engagement plate 7 approaches the driven engagement seat 5, the axial positioning strip 23 set on the outer wall of the frustum 8 first cuts into the axial positioning groove 504 at the bottom of the driven engagement seat 5. Since the inner diameter of the cross-section of the axial positioning groove 504 narrows linearly from bottom to top and has a chamfer at the opening, this structure can apply a tangential turning force to the rotating shaft 3 that has deviated, thereby achieving preliminary phase alignment in the circumferential direction, ensuring that the subsequent centering conical column 9 and the conical groove 502 can be smoothly nested, avoiding collision interference caused by mechanical transmission errors.

[0035] As the lifting mechanism continues to rise, the centering conical column 9 at the top of the active engagement plate 7 is fully inserted into the conical groove 502 at the bottom of the driven engagement seat 5. Utilizing the self-centering principle of conical surface mating, the inclined surface of the centering conical column 9 and the inner wall of the conical groove 502 generate radial extrusion force, forcing the rotation centerline of the rotating shaft 3 to coincide with the output shaft centerline of the rotary motor 6 on the same vertical axis. During this process, the pressure sensor 28 embedded at the top of the centering conical column 9 senses the axial contact force in real time and feeds back the electrical signal to the microcontroller after processing by a signal amplifier and analog-to-digital converter. When the feedback pressure value reaches the preset rigid contact threshold, the microcontroller precisely adjusts the upward displacement of the electric telescopic rod. Through this closed-loop control, the physical alignment between the active engagement plate 7 and the driven engagement seat 5 is ensured, and axial load damage to the support bearing of the rotating shaft 3 caused by excessive lifting is effectively prevented, providing a precise geometric reference for subsequent high-speed rotation.

[0036] At the instant the axial centering is completed, the pressure block 14 abuts against the bottom surface of the driven engagement seat 5 and moves downward relative to it as the active engagement disc 7 continues to rise. The pressure piston 12 moves downward within the pressure cylinder 11, compressing the hydraulic oil in the first hydraulic chamber 702. At this time, the microcontroller controls the first electrically controlled on / off valve 20 to open, and the pressurized hydraulic oil enters the pressurization chamber 703 through the first flow channel 704 and is distributed to the second hydraulic chambers 802 in each slide groove 801. Under the action of the static pressure of the hydraulic oil, the piston 18 is pushed to overcome the resistance of the second return spring 19, driving the wedge-shaped locking block 10 to pop out radially along the slide groove 801. The wedge-shaped inclined surface of the wedge-shaped locking block 10 is forcibly frictionally locked with the wedge-shaped groove 503 on the inner circumference of the driven engagement seat 5. Through this pressure-triggered hydraulic drive mechanism, a gapless torque transmission interface is constructed between the active engagement plate 7 and the driven engagement seat 5, forming a multi-point rigid constraint from centering to radial expansion and locking of the outer periphery. This completely eliminates the hidden danger of mechanical vibration of the split transmission structure under high-speed centrifugal state, and avoids the situation where mold shaking causes turbulence in the grout flow, resulting in wave-like undulation of the slurry surface, air entrainment, and bubble defects.

[0037] After hydraulic locking is completed, the rotary motor 6 starts and drives the active engagement plate 7 and the locked driven engagement seat 5 to rotate synchronously at high speed. At the same time, the grouting head 35 injects grout, and the flow control valve adjusts the slurry flow rate according to the process parameters. Since the active engagement plate 7 and the driven engagement seat 5 are rigidly connected in an interference state through the wedge locking block 10, the centrifugal inertial force generated during rotation is evenly distributed on multiple wedge grooves 503, which greatly enhances the dynamic balance characteristics of the system. This highly stable rotational environment allows the slurry to expel internal air bubbles with constant compressive stress and be evenly deposited on the inner wall of the mold under the action of centrifugal force field, thereby ensuring the consistency of the ceramic bottle blank wall thickness and fundamentally solving the problem of surface texture marks caused by the center of gravity shift.

[0038] After the grouting process is completed, the rotary motor 6 stops running. The microcontroller controls the second electrically controlled on / off valve 21 and the third electrically controlled on / off valve 22 to open, allowing the hydraulic oil in the second hydraulic chamber 802 to flow through the pressurization chamber 703 to the pressure relief chamber 706, and finally back to the first hydraulic chamber 702. At this time, the pressure in the second hydraulic chamber 802 is rapidly released, pushing the piston 18 to retract the wedge-shaped locking block 10 towards the center under the elastic force of the second return spring 19, releasing the radial locking state. Subsequently, the lifting mechanism drives the rotary drive mechanism to descend as a whole, the active engagement plate 7 completely disengages from the driven engagement seat 5, and the pressure block 14 returns to its original position under the action of the first return spring 15. When the active engagement plate 7 descends to the safe position, the electromagnetic pin pops out again from the insertion pin hole to limit the rotation of the rotating shaft 3, and the transmission mechanism then starts to transport the grouting mold to the next process, realizing fully automated cyclic production.
