Description

Technical Field

[0001] This invention relates to the field of hand mold forming technology, specifically to a superconducting energy-saving hand mold forming and preparation process. Background Technology

[0002] In the glove manufacturing industry, hand molds are the core molding component for producing various types of gloves (such as latex gloves and PVC gloves). Their molding quality directly determines the dimensional accuracy, surface smoothness, and performance of the gloves. Currently, hand mold molding mostly employs a slurry casting process. This process involves multiple steps, including mold opening and closing, slurry filling, drying and curing, and demolding. Existing molding equipment generally suffers from complex structures, high energy consumption, poor production continuity, and unstable molding accuracy, making it difficult to meet the demands of large-scale, high-efficiency production.

[0003] The conveying and flipping mechanisms of existing hand mold forming equipment are mostly independently designed, requiring additional specialized flipping drive devices to achieve mold posture switching. This not only increases the number of equipment parts and manufacturing costs, but also leads to increased energy consumption due to the difficulty of coordinating and controlling multiple power sources, and is prone to problems such as motion jamming and poor synchronization.

[0004] For example, Chinese invention patent CN115351963A, entitled "A Hand Mold Movement and Flipping Control Mechanism," discloses a hand mold flipping mechanism that includes a conveying device, a connecting rod, a bearing, and a transmission box. The hand mold flipping is achieved through the cooperation of the guide rail and the outer ring of the bearing. Although this technology can realize the movement and flipping function of the hand mold, it still requires an independent transmission box and transmission shaft assembly as the flipping drive structure. This results in structural redundancy and high power loss, which does not conform to the current development trend of energy conservation and emission reduction in the manufacturing industry.

[0005] Meanwhile, existing mold opening and closing mechanisms mostly adopt a single drive source and single-side transmission method, which easily leads to asynchronous movement on both sides of the mold and misalignment of the mating surfaces, thus affecting the forming accuracy of the hand-molded clay blank. Furthermore, most equipment has gaps in the connection between actions during processes such as capping, filling, and demolding, requiring machine stoppage to wait for the completion of each individual process before proceeding to the next, significantly reducing production efficiency. In addition, the mold opening and closing control of existing equipment relies heavily on sensors and complex electrical control systems, which not only increases equipment debugging and maintenance costs but also poses a risk of electrical failure, affecting the long-term stability of the equipment.

[0006] In addition, during mass production, existing equipment cannot achieve seamless integration of mold cleaning, material feeding and forming processes. Manual intervention is required to complete mold residue cleaning or hand mold transfer, which not only increases labor costs, but may also affect the production rhythm and product consistency due to human error. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a superconducting energy-saving hand mold forming and preparation process, which solves the problem that most flipping mechanisms are independently designed and require additional specialized flipping drive devices to achieve mold posture switching.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a superconducting energy-saving hand mold forming and preparation process, comprising the following steps:

[0009] Step 1: The raw materials for pulping are wet-milled to prepare slurry. The raw material ratio for pulping is as follows: 5-10 parts kaolin, 5-10 parts boron nitride, 10-15 parts potassium feldspar, 30-80 parts silicon carbide, 3-5 parts boron carbide, 1-3 parts lithium carbonate, 1-2 parts borax, 5-10 parts bentonite, 1-3 parts yttrium oxide, 3-5 parts lanthanum oxide, 1-3 parts calcium fluoride, 1-3 parts magnesium fluoride, 3-5 parts aluminum nitride, and 1-2 parts titanium dioxide.

[0010] Step 2: After removing iron and adding water to adjust the density of the mud to a certain level, it is sieved; the mud is then poured into the mold with the opening facing upwards to make a ceramic hand mold blank;

[0011] Step 3: Remove the clay blank from the hand mold with the opening facing down, and dry it at 20℃-35℃ for 20h-26h;

[0012] Step 4: After the dried clay blanks are coarsely brushed and finely brushed, they are naturally dried. Then, the dried clay blanks are sandblasted and hemped.

[0013] Step 5: Fire the hemp-coated clay blanks, then perform post-processing to obtain ceramic hand molds.

[0014] Furthermore, the superconducting energy-saving hand mold forming and preparation process includes a follower bracket and a first mold and a second mold slidably installed inside it. The mold closing or opening is achieved through the relative and opposite movements of the first mold and the second mold. The continuous operation of the mold is achieved through the cyclic conveying of the follower bracket and the first mold and the second mold.

[0015] The process involves cyclically conveying mold No. 1 and mold No. 2 to achieve the mold opening orientation required for filling and demolding; during conveying, the mold No. 1 and mold No. 2 are driven to open and close at designated positions to achieve fixed-point demolding and fixed-point filling.

[0016] Furthermore, the superconducting energy-saving hand mold forming and preparation process also includes:

[0017] Two stabilizing supports are arranged opposite each other, and a conveying mechanism is installed between the two stabilizing supports;

[0018] Multiple carrier boxes are installed at equal intervals along the conveying track of the conveying mechanism, and the multiple carrier boxes are circulated and conveyed by the conveying mechanism.

[0019] Mold No. 1 and Mold No. 2 are slidably installed in the carrier box. The carrier box is equipped with an opening and closing mechanism, which is connected to Mold No. 1 and Mold No. 2. Through the cooperation of the opening and closing mechanism and the conveying mechanism, Mold No. 1 and Mold No. 2 can move relative to each other or in opposite directions at a designated position.

[0020] The capping mechanism is installed on the stable support. When the first mold and the second mold move relative to each other, the capping mechanism places the third mold between the first mold and the second mold, so as to form a mold cavity for hand mold forming through the first mold, the second mold and the third mold.

[0021] The No. 3 mold has multiple grouting holes for filling with mud.

[0022] Furthermore, the conveying mechanism includes synchronous shafts rotatably mounted between the two stabilizer supports and located at both ends, with two conveying rollers fixed on the synchronous shafts, and the conveying rollers on the two synchronous shafts connected by a conveyor belt;

[0023] Both sides of the conveyor roller are provided with main positioning components, and connecting components are fixed on the main positioning components. The connecting components are fixed to the conveyor belt, and the main positioning components are connected to the conformal flipping mechanism installed on the stabilizing bracket.

[0024] Furthermore, the conformal flipping mechanism includes an outer plate fixed to one side of the two stabilizing supports. A first baffle and a second baffle are fixed on the outer plate, and a second positioning groove is formed by the first baffle and the second baffle. The main positioning component is inserted into the second positioning groove.

[0025] A branch plate is fixed on the main positioning component, and two auxiliary positioning components are fixed on the branch plate. A positioning groove is opened on the second baffle. One auxiliary positioning component is inserted into the positioning groove, and the other auxiliary positioning component is on the first baffle.

[0026] Furthermore, the opening and closing mechanism includes a bidirectional lead screw rotatably mounted on the top and bottom of the carrier box, and threaded sleeves with threaded engagement are fitted at both ends of the bidirectional lead screw, with the two threaded sleeves respectively fixed to mold No. 1 and mold No. 2;

[0027] A first transmission rod is rotatably mounted on the carrier box. The first transmission rod is connected to a bidirectional lead screw through two helical gear sets at both ends. The first transmission rod is connected to a fixed-point drive assembly installed on the main positioning component.

[0028] Furthermore, the fixed-point drive assembly includes a second transmission rod rotatably installed inside the main positioning component. A gear is coaxially rotatably installed on one end of the main positioning component away from the carrier box. The gear is coaxially fixed with the second transmission rod. The second transmission rod is connected to the first transmission rod through a first bevel gear set.

[0029] A second rack plate is fixed to the inner wall of the first baffle, and a first rack plate is fixed to the outer wall of the second baffle. Both the first rack plate and the second rack plate are in the movement path of the gear, and both the first rack plate and the second rack plate cooperate with the gear.

[0030] Furthermore, the cover mounting mechanism includes a follower bracket slidably mounted on a stabilizing bracket, and a second guide rod is fixed on both sides of the stabilizing bracket. A sliding sleeve fixed to the follower bracket is slidably mounted on the second guide rod, and a spring is sleeved on the second guide rod.

[0031] The first carrier plate is slidably installed at the bottom of the follower bracket. The second carrier plate is slidably installed at the bottom of the first carrier plate through the first guide rod. A turntable is rotatably installed on the second carrier plate. Multiple positioning shafts are fixed at the bottom of the turntable. The positioning shafts cooperate with the feeding assembly installed on the follower bracket.

[0032] A motor is fixed to the bottom of the second carrier plate, and the output shaft of the motor is connected to the turntable through the second bevel gear set.

[0033] A cylinder is slidably mounted on the top of the follower bracket. The movable shaft of the cylinder is fixed to the second carrier plate. A cylinder is fixed on one side of the follower bracket. The movable rod of the cylinder is fixed to the first carrier plate.

[0034] Furthermore, the feeding assembly includes a storage box that passes through and is fixed to the follower bracket, and a tray is fixed to the bottom of the storage box;

[0035] A feeding plate is slidably mounted on the pallet, and a No. 3 cylinder is fixed at the bottom of the pallet, with the moving rod of the No. 3 cylinder fixed to the feeding plate;

[0036] The storage box is equipped with a movable groove for the movement of mold number three and the feeding plate.

[0037] Furthermore, a discharge plate is fixed between the two stabilizers, and the discharge plate has multiple through slots equidistantly spaced.

[0038] One end of the discharge plate is arc-shaped, and a discharge plate is vertically and slidably installed in a through groove near the arc-shaped part.

[0039] The present invention has the following beneficial effects:

[0040] I. The superconducting energy-saving hand mold forming and preparation process, through the coordination of the conformal flipping mechanism and the conveying mechanism, utilizes the conformal cooperation of the secondary positioning component of the main positioning component with the first baffle and the first positioning groove to naturally achieve 180° flipping of the carrier box and the mold during the conveying process, without the need for an additional independent flipping drive structure.

[0041] This not only reduces the number of equipment parts and mechanical wear, but also, because it does not require additional power to drive the rotation, it further aligns with the superconducting energy-saving concept and significantly reduces overall energy consumption.

[0042] II. The superconducting energy-saving hand mold forming process utilizes a bidirectional lead screw synchronous drive at the top and bottom of the carrier box for the opening and closing mechanism. This, combined with the fixed connection between the threaded sleeve and the mold, enables synchronous relative / opposite movement of molds one and two, avoiding tilting deviations during mold opening and closing and ensuring precise overlap of the mating surfaces. Simultaneously, the self-locking characteristic of the threaded drive provides stable clamping force without the need for additional clamping devices, simplifying the mechanism design and effectively improving the forming accuracy and consistency of the hand mold blank.

[0043] Third, this superconducting energy-saving hand mold forming process, through a capping mechanism, enables the simultaneous loading, positioning, placement, and locking of the third mold during the horizontal conveying and relative closing of the first and second molds, without requiring machine downtime to wait for the capping action. This dynamic collaborative mode breaks the limitations of traditional step-by-step operations, significantly improves production cycle time, and realizes continuous assembly line operation for hand mold forming.

[0044] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0071] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] The following is based on Figures 1-25 This invention describes the superconducting energy-saving hand mold forming and preparation process provided in the embodiments of the present invention.

[0073] like Figures 1-25 As shown, an embodiment of the present invention provides a technical solution comprising the following steps:

[0074] Step 1: Prepare slurry by wet ball milling the raw materials;

[0075] The raw material ratio for pulping is as follows:

[0076] Kaolin 5-10 parts, boron nitride 5-10 parts, potassium feldspar 10-15 parts, silicon carbide 30-80 parts, boron carbide 3-5 parts, lithium carbonate 1-3 parts, borax 1-2 parts, bentonite 5-10 parts, yttrium oxide 1-3 parts, lanthanum oxide 3-5 parts, calcium fluoride 1-3 parts, magnesium fluoride 1-3 parts, aluminum nitride 3-5 parts, titanium dioxide 1-2 parts.

[0077] By introducing materials such as silicon carbide, aluminum nitride, boron nitride, lanthanum oxide, and calcium fluoride, the density and thermal shock resistance of the hand mold are improved, and its thermal conductivity and thermal radiation are enhanced, making glove production more energy-efficient and heat-saving.

[0078] The ceramic hand mold of this invention, suitable for the production of PVC and nitrile rubber gloves, incorporates kaolin to form a stable crystal phase structure. The addition of bentonite further promotes the formation of mullite and cordierite phases, giving the ceramic hand mold good corrosion resistance and thermal shock resistance. The addition of boron nitride further increases the corrosion resistance of the ceramic body. Yttrium oxide further improves the corrosion resistance of the ceramic hand mold, while silicon carbide increases the strength and density of the ceramic hand mold, resulting in faster heat conduction and reduced glove production costs, achieving energy saving and consumption reduction.

[0079] The synergistic effect of the raw materials results in good molding performance of the prepared blank, significantly improving the thermal conductivity, corrosion resistance, and oxidation resistance of the ceramic hand mold. Furthermore, the total shrinkage rate of the ceramic hand mold is small, and its service life and pass rate are significantly improved.

[0080] Step 2: After removing iron and adjusting the density of the mud to a certain level by adding water, the mud is sieved. The density of the mud is adjusted to 1.8-1.9 g / cm3 by adding water and sieve through a 180-200 mesh screen. The mud is then poured into the mold with the opening facing upward to make a ceramic hand mold blank 6.

[0081] The hand mold is a plaster mold.

[0082] Step 3: Remove the hand mold clay blank 6 from the hand mold with the opening facing down, and dry it at 20℃-35℃ for 20h-26h.

[0083] Step 4: After the dried clay blanks are coarsely brushed and finely brushed, they are naturally air-dried. Then, the dried clay blanks are sandblasted and roughened. Ceramic balls with a particle size of 0.8-1.0mm are used to sandblast and roughen the areas that need roughening. The pressure during roughening is 0.3-0.4MPa.

[0084] Step 5: Fire the hemp-coated clay blanks, then perform post-processing to obtain ceramic hand molds.

[0085] The superconducting energy-saving hand mold forming and preparation process includes a follower bracket 3 and a first mold 201 and a second mold 202 slidably installed inside it. The mold is closed or opened by the relative and opposite movements of the first mold 201 and the second mold 202. The mold is continuously operated by cyclically conveying the follower bracket 3 and the first mold 201 and the second mold 202.

[0086] Specifically, by cyclically conveying mold No. 1 201 and mold No. 2 202, the orientation of the mold opening required for filling and demolding is changed; during conveying, the mold No. 1 201 and mold No. 2 202 are driven to open and close at designated positions to achieve fixed-point demolding and fixed-point filling.

[0087] The superconducting energy-saving hand mold forming and preparation process also includes:

[0088] Two opposing stabilizing supports 1 are provided, and a conveying mechanism is installed between the two stabilizing supports 1.

[0089] Multiple carrier boxes 2 are installed at equal intervals on the conveying mechanism along the conveying trajectory of the conveying mechanism, and the multiple carrier boxes 2 are circulated and conveyed by the conveying mechanism.

[0090] Mold 201 and Mold 202 are slidably mounted in the carrier box 2. The carrier box 2 is equipped with an opening and closing mechanism, which is connected to Mold 201 and Mold 202. The opening and closing mechanism and the conveying mechanism work together to make Mold 201 and Mold 202 move relative to each other or in opposite directions at a specified position.

[0091] The cover mechanism installed on the stable support 1, when the first mold 201 and the second mold 202 move relative to each other, places the third mold 203 between the first mold 201 and the second mold 202, so as to form a mold cavity for hand mold forming through the first mold 201, the second mold 202 and the third mold 203.

[0092] Mold No. 3, 203, has multiple grouting holes 204 for filling mud.

[0093] In this embodiment of the invention, the carrier box 2, mold 201, and mold 202 are cyclically conveyed by a conveying mechanism. Two states may occur during the conveying process:

[0094] State 1: Carrier box 2, mold 1 201, and mold 202 are at the top, and mold 3 203 is facing upwards. This state is the filling state.

[0095] State 2: Carrier box 2, mold 1 201, and mold 202 are at the bottom, and mold 3 203 is facing down. This state is the demolding state.

[0096] When mold 1 201 and mold 202 are in the filling state, they are driven to move relative to each other by the opening and closing mechanism. When mold 1 201 and mold 202 are in the demolding state, they are driven to move in opposite directions by the opening and closing mechanism, so that the hand mold clay blank 6 is demolded.

[0097] When mold No. 1 201 and mold No. 2 202 are in the filling state, the slurry is filled into the mold cavity through the slurry filling hole 204 by the slurry filling equipment. Then, the slurry is dried by the drying equipment to reduce the moisture and form the shape. Then, it is demolded by the conveying movement to the demolding state to obtain the hand mold clay blank 6.

[0098] The conveying mechanism includes a synchronous shaft 402 rotatably mounted between the two stable supports 1 and located at both ends. Two conveying rollers 4 are fixed on the synchronous shaft 402, and the conveying rollers 4 on the two synchronous shafts 402 are connected by a conveyor belt 401.

[0099] Both sides of the carrier box 2 are fixed with main positioning components 209, and the main positioning components 209 are fixed with connecting components 2017. The connecting components 2017 are fixed with the conveyor belt 401, and the main positioning components 209 are connected to the conformal flipping mechanism installed on the stable support 1.

[0100] In this embodiment of the invention, a drive motor is fixed on the stabilizing bracket 1. The output shaft of the drive motor is coaxially fixed with one of the synchronous shafts 402. When the drive motor is working, it drives one of the synchronous shafts 402 to rotate. The synchronous shaft 402 drives the conveyor roller 4 to rotate, thereby conveying the conveyor belt 401. Since the main positioning component 209 is fixed to the conveyor belt 401 through the connector 2017, the conveyor belt 401 drives the carrier box 2 and the first mold 201 and the second mold 202 inside it to move along the conveying path through the connector 2017 and the main positioning component 209 during the conveying process.

[0101] The conformal flipping mechanism is used to limit and guide the main positioning component 209 and the carrier box 2 during transportation, ensuring the stability of the carrier box 2 as it moves along the path.

[0102] Among them, such as Figure 2 As shown, mold 201 and mold 202 are in a combined state when they are on top, and in a separated state when they are on the bottom. Mold 201 and mold 202 will rotate 180° as they are conveyed.

[0103] The conformal flipping mechanism includes an outer plate 101 fixed to one side of the two stabilizing supports 1. A first baffle 102 and a second baffle 103 are fixed on the outer plate 101. A second positioning groove 105 is formed by the first baffle 102 and the second baffle 103. The main positioning component 209 is inserted into the second positioning groove 105.

[0104] A branch plate 2010 is fixed on the main positioning component 209, and two auxiliary positioning components 2013 are fixed on the branch plate 2010. A first positioning groove 104 is opened on the second baffle 103. One auxiliary positioning component 2013 is inserted into the first positioning groove 104, and the other auxiliary positioning component 2013 is located on the first baffle 102.

[0105] In this embodiment of the invention, the auxiliary positioning component 2013 cooperates with the first baffle 102 and the first positioning groove 104 to apply a limiting effect to the main positioning component 209 during horizontal transport, so that the main positioning component 209 will not flip when moving horizontally, and when it moves to the arc part, it follows the shape and drives the main positioning component 209 and the carrier box 2 to flip 180°.

[0106] This conveying method allows for a flipping effect without the need for an additional flipping structure. Please refer to [link / reference]. Figure 23 The trajectory of its movement.

[0107] The opening and closing mechanism includes a bidirectional lead screw 205 rotatably mounted on the top and bottom of the carrier box 2. Both ends of the bidirectional lead screw 205 are fitted with threaded sleeves 206 that are threaded with it. The two threaded sleeves 206 are respectively fixed to the first mold 201 and the second mold 202.

[0108] A first transmission rod 208 is rotatably mounted on the carrier box 2. The first transmission rod 208 is connected to a bidirectional lead screw 205 through two helical gear sets 207 at both ends. The first transmission rod 208 is connected to a fixed-point drive assembly installed on the main positioning component 209.

[0109] In this embodiment of the invention, the first transmission rod 208 is driven to rotate at a designated position by a fixed-point drive component. When the first transmission rod 208 rotates, the bidirectional lead screw 205 is driven to rotate through the helical gear set 207 at both ends. When the bidirectional lead screw 205 rotates, it drives the two threaded sleeves 206 to move relative to or opposite to each other through the threaded engagement with the two threaded sleeves 206. This drives the first mold 201 and the second mold 202 to move relative to or opposite to each other through the threaded sleeves 206, thereby realizing the opening and closing of the first mold 201 and the second mold 202.

[0110] Among them, the helical gear set 207 includes two meshing helical gears, which are coaxially fixed with the first transmission rod 208 and the double-acting lead screw 205, respectively.

[0111] Since the mating surfaces of mold 201 and mold 202 need to overlap when they are joined, meaning that they cannot tilt during relative movement, the preferred method to drive the relative movement of mold 201 and mold 202 is to use synchronous drive from the top and bottom. Furthermore, the speed of movement needs to be synchronized. Therefore, using a threaded drive to drive the relative movement of mold 201 and mold 202 is the simplest and meets the requirements.

[0112] Furthermore, mold No. 1 201 and mold No. 2 202 require a certain clamping force when they are combined, and the threaded drive has a self-locking function, which can meet the clamping requirements of the combination.

[0113] The fixed-point drive assembly includes a second transmission rod 2012 rotatably installed in the main positioning component 209. A gear 2011 is rotatably installed coaxially at the end of the main positioning component 209 away from the carrier box 2. The gear 2011 is coaxially fixed with the second transmission rod 2012. The second transmission rod 2012 is connected to the first transmission rod 208 through the first bevel gear set 2014.

[0114] A second rack plate 2016 is fixed to the inner wall of the first baffle 102, and a first rack plate 2015 is fixed to the outer wall of the second baffle 103. Both the first rack plate 2015 and the second rack plate 2016 are in the movement path of the gear 2011, and both the first rack plate 2015 and the second rack plate 2016 cooperate with the gear 2011.

[0115] In this embodiment of the invention, gear 2011 moves along the conveying path of conveyor belt 401 with main positioning component 209. When gear 2011 moves to the position of rack plate 2015, it continues to move, causing gear 2011 to mesh with rack plate 2015, thereby driving gear 2011 to rotate. When gear 2011 rotates, it drives transmission rod 2012 to rotate. When transmission rod 2012 rotates, it drives transmission rod 208 to rotate through bevel gear set 2014. The rotation of transmission rod 208 corresponds to the synchronous driving of two bidirectional lead screws 205 to rotate. At this time, it drives mold 201 and mold 202 to move in opposite directions.

[0116] After gear 2011 moves to the position of rack plate 2016, it continues to move. By meshing with rack plate 2016, gear 2011 is driven to rotate in the opposite direction, which in turn drives transmission rod 2012 and transmission rod 208 to rotate in the opposite direction. At this time, mold 1 201 and mold 202 move relative to each other.

[0117] The first bevel gear set 2014 includes two meshing bevel gears, which are coaxially fixed to the first transmission rod 208 and the second transmission rod 2012, respectively.

[0118] The cover mounting mechanism includes a follower bracket 3 slidably mounted on a stabilizing bracket 1. A second guide rod 306 is also fixed on both sides of the stabilizing bracket 1. A sliding sleeve fixed to the follower bracket 3 is slidably mounted on the second guide rod 306. A spring 307 is sleeved on the second guide rod 306.

[0119] The first carrier plate 3010 is slidably installed at the bottom of the follower bracket 3. The second carrier plate 3011 is slidably installed at the bottom of the first carrier plate 3010 through the first guide rod 305. A turntable 3012 is rotatably installed on the second carrier plate 3011. Multiple positioning shafts 3015 are fixed at the bottom of the turntable 3012. The positioning shafts 3015 cooperate with the feeding assembly installed on the follower bracket 3.

[0120] A motor 3013 is fixed to the bottom of the second carrier plate 3011, and the output shaft of the motor 3013 is connected to the turntable 3012 through the second bevel gear set 3014.

[0121] The first cylinder 301 is slidably installed on the top of the follower bracket 3. The movable shaft of the first cylinder 301 is fixed to the second carrier plate 3011. The second cylinder 303 is fixed on one side of the follower bracket 3. The movable rod of the second cylinder 303 is fixed to the first carrier plate 3010.

[0122] The feeding assembly includes a storage box 302 that passes through and is fixed to the follower bracket 3, and a tray 308 is fixed to the bottom of the storage box 302;

[0123] A feeding plate 304 is slidably mounted on the pallet 308, and a No. 3 cylinder 309 is fixed at the bottom of the pallet 308. The movable rod of the No. 3 cylinder 309 is fixed to the feeding plate 304.

[0124] The storage box 302 has a movable groove for the movement of the No. 3 mold 203 and the feeding plate 304.

[0125] In this embodiment of the invention, when the second cylinder 303 is working, it drives the extension or retraction of its movable rod to drive the first carrier plate 3010, the first cylinder 301, the second carrier plate 3011 and other related components to move horizontally; when the first cylinder 301 is working, it drives the second carrier plate 3011 to move vertically.

[0126] When the third cylinder 309 is working, its movable rod drives the loading plate 304 to slide on the pallet 308, and pushes the third mold 203 in the storage box 302 to the designated position. The pallet 308 is fixed with a positioning baffle 3016, which limits the stroke of the third mold 203 to ensure the accuracy of the position.

[0127] Then, the No. 2 carrier plate 3011, turntable 3012, and positioning shaft 3015 are driven to descend vertically by the No. 1 cylinder 301. At the same time, the motor 3013 works. When the motor 3013 works, its output shaft drives the turntable 3012 to rotate through the No. 2 bevel gear set 3014, so as to synchronously drive multiple positioning shafts 3015 to rotate around the axis of the turntable 3012. With the descent of the positioning shaft 3015, the positioning shaft 3015 is inserted into the grouting hole 204 of the No. 3 mold 203. The positioning shaft 3015 is fixed to the grouting hole 204 of the No. 3 mold 203 by the expansion member installed on the positioning shaft 3015.

[0128] Then, the second cylinder 303 drives the first carrier plate 3010 to move horizontally, carrying the third mold 203 to move above the movement path of the first mold 201 and the second mold 202. When the third mold 203 is between the first mold 201 and the second mold 202, the first cylinder 301 drives the second carrier plate 3011 and the third mold 203 to descend again, so that the third mold 203 moves between the first mold 201 and the second mold 202.

[0129] At this time, mold 1 201 and mold 202 are moving horizontally and simultaneously triggering the opening and closing mechanism. That is, mold 1 201 and mold 202 move horizontally in sync while moving relative to each other. At this time, mold 3 203 is placed between mold 1 201 and mold 202. It will drive mold 3 203, positioning shaft 3015 and components mounted on follower bracket 3 to move along with mold 1 201 and mold 202 through horizontal movement. After molds 01 and 202 complete their relative movement, i.e., after merging, the positioning shaft 3015 is driven to rise, causing it to disengage from mold 3. When the follower bracket 3 moves horizontally between molds 1 and 202, it drives the sliding sleeve to follow the movement. The sliding sleeve compresses the spring 307, allowing it to store a certain amount of elastic potential energy. When the storage box 302 and the positioning shaft 3015 disengage, the elastic potential energy of the spring 307 is released, causing the follower bracket 3 to reset.

[0130] The above-mentioned motion states achieve the dynamic coordination state of mold 1 201 and mold 202 during normal cyclic conveying. Before merging, mold 3 203 is installed between mold 1 201 and mold 202, and mold 3 203 is locked by the relative movement of mold 1 201 and mold 202.

[0131] The expansion component includes an elastic membrane 3017 fixed on the positioning shaft 3015. When the positioning shaft 3015 is inserted into the grouting hole 204, the elastic membrane 3017 is inflated by inflating it to fix it to the No. 3 mold 203 and the grouting hole 204.

[0132] A discharge plate 5 is also fixed between the two stabilizers 1, and multiple through slots 502 are equally spaced on the discharge plate 5;

[0133] One end of the discharge plate 5 is arc-shaped, and a discharge plate 501 is vertically and slidably installed in a through groove 502 near the arc-shaped part.

[0134] In this embodiment of the invention, when mold 1 201 and mold 202 move in opposite directions while moving horizontally in sync, the arc-shaped part of the discharge plate 5 smoothly discharges the mold 1 201 and mold 202. Finally, the hand mold clay blank 6 stops on the discharge plate 501. The discharge plate 501 is driven by external power to descend and stabilize the mechanism, thus completing the discharge and conveying it to the next process.

[0135] High-pressure air guns can be installed at the remaining slots 502 to clean residual powder inside mold 1 201 and mold 202.

[0136] During use (operation), the drive motor drives one of the synchronous shafts 402 to rotate, which in turn drives the conveyor rollers 4 at both ends to rotate. The conveyor rollers 4 drive another set of synchronous shafts 402 to rotate synchronously via the conveyor belt 401, forming a stable conveying circuit. The conveyor belt 401 is fixed to the main positioning component 209 via the connector 2017, thereby driving the main positioning component 209 and the connected carrier box 2 to move. The carrier box 2 then drives the first mold 201 and the second mold 202 inside to move cyclically along the conveying path. During the movement of the main positioning component 209, the two auxiliary positioning components 2013 on its branch plate 2010 cooperate with the conformal flipping mechanism. One auxiliary positioning component 2013 is inserted into the first positioning groove 104 of the second baffle 103, and the other auxiliary positioning component 2013 is attached to the first baffle 102. During the horizontal conveying stage, the main positioning component 209 is prevented from flipping by the two limiting mechanisms. When it moves to the arc section of the conveying path, the auxiliary positioning component 2013 follows the trajectory of the first positioning groove 104 and the first baffle 102, causing the main positioning component 209 and the carrier box 2 to flip 180°, so that the carrier box 2 alternately switches to the filling state with the top third mold 203 facing upward and the demolding state with the bottom third mold 203 facing downward.

[0137] The mold opening and closing action is achieved by the linkage between the opening and closing mechanism and the fixed-point drive assembly: the main positioning component 209 drives the gear 2011 to move along the conveying path. When it moves to the demolding state area, the gear 2011 meshes with the first rack plate 2015 on the outer wall of the second baffle 103. The first rack plate 2015 drives the gear 2011 to rotate, and the gear 2011 drives the second transmission rod 2012 to rotate. The second transmission rod 2012 drives the first transmission rod 208 to rotate through the first bevel gear set 2014. The first transmission rod 208 drives the bidirectional lead screw 205 at the top and bottom of the carrier box 2 to rotate synchronously through the helical gear sets 207 at both ends. The bidirectional lead screw 205 drives the bidirectional lead screw 205 to rotate synchronously through the screw... The threaded engagement drives the two threaded sleeves 206 to move in opposite directions, which in turn drives the first mold 201 and the second mold 202 to move in opposite directions to achieve mold opening. When the gear 2011 moves to the filling state area, the gear 2011 meshes with the second rack plate 2016 on the inner wall of the first baffle 102. The second rack plate 2016 drives the gear 2011 to rotate in the opposite direction. Through the reverse linkage of the second transmission rod 2012, the first bevel gear set 2014, the first transmission rod 208 and the helical gear set 207, the double-acting screw 205 is driven to rotate in the opposite direction, so that the threaded sleeve 206 drives the first mold 201 and the second mold 202 to move in opposite directions to achieve mold closing.

[0138] During the mold closing process, the capping mechanism operates synchronously: Cylinder 309 drives the loading plate 304 to slide on the support plate 308, pushing the mold 203 in the storage box 302 to the positioning baffle 3016 for a limit position; subsequently, Cylinder 1 drives Carrier 3011 to move downwards, which in turn drives Turntable 3012 and positioning shaft 3015 to descend synchronously. Simultaneously, Motor 3013 drives Turntable 3012 to rotate via Bevel Gear Set 3014, which in turn drives Positioning Shaft 3015 to rotate. This, combined with the descent, allows Positioning Shaft 3015 to precisely insert into the grouting hole 204 of Mold 203, inflating the elastic membrane 3017 on Positioning Shaft 3015 to expand it, thus achieving the positioning shaft 3015's precise insertion into the grouting hole 204. 15 is fixed to mold 203; then cylinder 303 drives carrier plate 3010 to move horizontally, carrier plate 3010 drives carrier plate 3011, turntable 3012 and mold 203 to move synchronously, transporting mold 203 between mold 1 and mold 202. Cylinder 301 drives carrier plate 3011 to descend again, so that mold 203 is in place; at this time, mold 1 and mold 202 continue to move relative to each other, driving mold 203 to move synchronously and complete mold closing and locking. Then, positioning shaft 3015 releases air, retracts and rises to disengage from mold 203. The follower bracket 3 drives each component to reset under the elastic potential energy of spring 307.

[0139] After the mold is locked, a sealed mold cavity is formed. The existing slurry filling equipment fills the mold cavity with slurry through the slurry filling hole 204 of the No. 3 mold 203. After filling, the slurry is dried by a continuous drying equipment to reduce the moisture content and solidify it. After molding, the carrier box 2 continues to move with the conveyor belt 401. When switching to the demolding state, the No. 1 mold 201 and the No. 2 mold 202 move in opposite directions to open the mold. The hand mold clay blank 6 moves with the carrier box 2 to the discharge plate 5. It is smoothly guided by the arc part of the discharge plate 5 and finally falls onto the discharge plate 501. The discharge plate 501 slides down and carries the hand mold clay blank 6 to the next process. At the same time, the high-pressure air gun in the other through grooves 502 on the discharge plate 5 is activated to clean the residual powder in the No. 1 mold 201 and the No. 2 mold 202, completing the single molding process. The carrier box 2 continues to circulate with the conveyor belt 401 and enters the next molding process.
