Abstract
Description
Technical Field
[0001] This invention relates to the field of ceramic slip casting equipment technology, and in particular to a slip casting machine using a stacked toilet mold. Background Technology
[0002] In the prior art, the toilet blank is made by bonding the seat blank, water channel blank and outer shell blank together, and then sintering at high temperature to make a ceramic toilet.
[0003] To improve the production efficiency of large-scale ceramic toilet manufacturing, existing technology uses seat molds, water channel molds, and outer shell molds, which are then cast into seat ring blanks, water channel blanks, and outer shell blanks using different slip casting machines. These blanks are then transported to a robotic assembly station via three conveyor lines. The robot uses three robotic arms to grasp each blank, and adhesive is sprayed onto the areas requiring bonding. The blanks are then stacked from bottom to top and bonded together. Finally, the toilet is sintered in a high-temperature kiln to produce the ceramic toilet.
[0004] While the above production model has high production efficiency, it requires a large amount of space for manufacturing equipment, long production line turnaround time, high turnaround costs, and a large minimum order quantity.
[0005] As economic levels rise, people have increasingly higher demands for personalized products, leading to a continuous increase in the variety of ceramic toilet styles.

Figure 4 This is a schematic diagram of the upper water channel mold 13 and lower water channel mold 14 in the open state of the injection molding machine using the stacked toilet mold. Figure 5 This is a schematic diagram of the structure in which the waterway blank 10 in the injection molding machine using the stacked toilet mold is taken out and placed on the support plate 8.
[0083] like Figure 1 , 2 As shown in Figures 4 and 5, the grouting operation steps of the grouting molding machine using the stacked toilet mold of the present invention are as follows:
[0084] 1. Mold Closing and Grouting: The mold closing cylinder 201 is activated and extends downward. The bottom end of the mold closing cylinder 201 drives the upper mold 11 of the outer shell to move downward, causing the upper mold 11 of the outer shell to approach and close with the lower mold 12 of the outer shell, the upper mold 13 of the water channel to approach and close with the lower mold 14 of the water channel, and the upper mold 15 of the seat ring to approach and close with the lower mold 16 of the seat ring. At this time, the three pairs of mold locking cylinders 17 are activated, respectively closing the upper mold 11 of the outer shell and the lower mold 12 of the outer shell, and the upper mold 13 of the water channel and the lower mold 16 of the water channel. 14 and the upper mold 15 of the seat ring are locked with the lower mold 16 of the seat ring, forming the outer shell mold cavity, water channel mold cavity and seat ring mold cavity arranged from top to bottom in the toilet mold 1. Then the grouting cylinder is started and grout is injected into the outer shell mold cavity, water channel mold cavity and seat ring mold cavity through the grouting holes provided in each mold. After the grouting pressure reaches 20MPa by the pressure switch, the oil pump of the grouting cylinder stops pressurizing and maintains the pressure so that the grout forms the corresponding blank in the corresponding mold cavity.
[0085] 2. Slurry discharge and consolidation: Each mold has an air blowing hole on its rear end face, left side face, and right side face. Each mold also has a slurry discharge valve on its rear end face that is connected to the corresponding mold cavity. Compressed gas of 0.2MPa is injected into the corresponding mold cavity through the air blowing hole. After opening the slurry discharge valve to discharge the excess slurry in the corresponding mold cavity, the slurry discharge valve is closed. Then, slurry is injected into each mold cavity to consolidate the blank in each mold cavity, so that the blank in each mold cavity forms a complete and flawless whole.
[0086] 3. Mold Opening and Seat Ring Blank Removal: The mold closing cylinder 201 depressurizes, the top beam 200 descends, and a pair of locking cylinders 17 located on the left and right sides of the top of the lower seat ring mold 16 close and retract, unlocking the upper seat ring mold 15 from the lower seat ring mold 16. Then, 0.2MPa of compressed air is injected into the lower seat ring mold 16 to demold the seat ring blank. Multiple screw elevators 301 synchronously drive the corresponding lifting screws 302 to rotate, and through the top beam 200, drive the upper part of the toilet mold 1, which is connected and locked together, to rise, allowing the upper seat ring mold 15 to unlock. The lower mold 16 of the seat ring separates from the upper mold; then the lifting device 6 is activated and drives the rotating device 7 to move upward to between the upper mold 15 and the lower mold 16 of the seat ring. At the same time, the rotating device 7 is activated and drives the robotic arm 9, which holds the blank support plate 8, to rotate and enter below the upper mold 15 of the seat ring. After the blank support plate 8 supports the seat ring blank, the rotating device 7 drives the robotic arm 9 to rotate to the front of the upper mold 15 of the seat ring. The lifting device 6 then drives the rotating device 7 to descend to the lowest position. Then, adhesive putty is applied to the inner edge of the seat ring blank by manual labor or a glue applicator.
[0087] 4. Open the mold and take out the water channel blank: such as Figure 5As shown, multiple screw elevators 301 synchronously drive the corresponding lifting screws 302 to rotate, and drive the top beam 200 and toilet mold 1 to lower downwards, causing the upper seat mold 15 and the lower seat mold 16 to close. A pair of locking cylinders 17 located on the left and right sides of the top of the lower seat mold 16 are activated and extended relative to each other, locking the upper seat mold 15 and the lower seat mold 16. Then, a pair of locking cylinders 17 located on the left and right sides of the top of the lower water channel mold 14 close and retract, unlocking the upper water channel mold 13 and the lower water channel mold 14. Next, 0.2 MPa of compressed air is injected into the lower water channel mold 14 to demold the water channel blank. Afterwards, the multiple screw elevators 301 synchronously drive the corresponding lifting screws 302 to rotate, and through the top beam 200... 00 drives the upper part of the toilet mold 1, which is connected and locked together, to rise, so that the upper mold 13 and the lower mold 14 of the water channel are separated. Then, the lifting device 6 is opened and drives the rotating device 7 to move upward between the upper mold 13 and the lower mold 14 of the water channel. At the same time, the rotating device 7 is opened and drives the mechanical arm 9, which is placed on the blank support plate 8, to enter below the upper mold 13 of the water channel. The blank support plate 8, which is placed on the seat ring blank, supports the water channel blank 10. The seat ring blank and the water channel blank 10 are bonded together. Then, the rotating device 7 drives the mechanical arm 9 to rotate to the front of the upper mold 13 of the water channel. The lifting device 6 drives the rotating device 7 to descend. Then, the adhesive putty is applied to the outer edge of the water channel blank and the seat ring blank by manual labor or glue applicator.
[0088] 5. Demolding the outer shell blank: Multiple screw elevators 301 synchronously drive the corresponding lifting screws 302 to rotate, and drive the top beam 200 and toilet mold 1 to lower downwards, so that the upper water channel mold 13 and the lower water channel mold 14 close together. A pair of locking cylinders 17 on the left and right sides of the top of the lower water channel mold 14 are activated and extended relative to each other, locking the upper water channel mold 13 and the lower water channel mold 14. Then, a pair of locking cylinders 17 on the left and right sides of the top of the lower outer shell mold 12 close and retract, so that the upper outer shell mold 11 and the lower outer shell mold 12 are unlocked. Then, 0.2MPa of compressed air is injected into the lower outer shell mold 12 to demold the outer shell blank. Multiple screw elevators 301 then synchronously drive the corresponding lifting screws 302 to rotate, and drive the upper part of the toilet mold 1, which is connected and locked together, to rise through the top beam 200, so that... The upper mold 11 and the lower mold 12 of the outer shell are separated vertically. Then, the lifting device 6 is activated and drives the rotating device 7 to move upward between the upper mold 11 and the lower mold 12 of the outer shell. At the same time, the rotating device 7 is activated and drives the mechanical arm 9, which holds the blank support plate 8, to enter below the upper mold 11 of the outer shell. The blank support plate 8, which holds the water channel blank 10 and the seat ring blank, supports the outer shell blank. The outer shell blank, the seat ring blank, and the water channel blank 10 are bonded together. Then, the rotating device 7 drives the mechanical arm 9 to rotate in front of the upper mold 11 of the outer shell. The lifting device 6 drives the rotating device 7 to descend to the lowest position. At this point, the removal of the outer shell blank, the seat ring blank, and the water channel blank 10 of a set of toilet mold 1 is completed. After that, the bonded outer shell blank, the seat ring blank, and the water channel blank 10 can be placed on the conveyor line and transported to the kiln for sintering.

A pair of locking cylinders 17 located on the left and right sides of the top of the lower outer shell mold 12 extend relative to each other, locking the upper outer shell mold 11 and the lower outer shell mold 12.
[0090] 7. Repeat steps 1-6 above to perform the next cycle of grouting, blank forming, and blank removal of the stacked toilet mold.
[0091] The injection molding machine using a stacked toilet mold of the present invention can complete the injection molding of the toilet shell blank, seat blank, and water channel blank in one station. The seat blank, water channel blank 10, and shell blank can be removed sequentially by the cooperation of the robotic arm 9, lifting device 6, rotating device 7, and blank support plate 8. When removing the blanks, adhesive can be applied manually or by spraying adhesive with an adhesive applicator to bond the shell blank, seat blank, and water channel blank 10 together. Each injection molding machine using a stacked toilet mold can be used as a production unit to produce one toilet. Therefore, the injection molding machine using a stacked toilet mold of the present invention is suitable for small-batch production, has the advantages of convenient production switching and flexible production scheduling, and also has the advantages of compact structure and small footprint, thus having good economic benefits.
[0092] Furthermore, it also includes a top beam 200, a mold closing cylinder 201, a frame 202, a guide column 203 and a base plate 204, as well as two sets of tilting devices 3;
[0093] Multiple screw elevators 301 and multiple lifting screws 302 are installed on the left and right sides of the frame 202. A crossbeam 2021 extending in the front-back direction is also provided in the middle of the left and right sides of the frame 202.
[0094] The top beam 200 is mounted on the top of the frame 202, the base plate 204 is mounted on the bottom of the frame 202, the top of the guide column 203 is connected to the bottom surface of the top beam 200, and the bottom of the guide column 203 can move up and down through the crossbeam 2021.
[0095] The toilet mold 1 is located inside the frame 202; the output end of the mold closing cylinder 201 is downward and connected to the top of the upper mold 11 of the outer shell, the top end of the mold closing cylinder 201 is connected to the middle of the top beam 200, and the bottom of the lower mold 16 of the seat ring is fixed to the top surface of the base plate 204.
[0096] The tilting device 3 includes a support frame 31, a rotating shaft 32, a rotating shaft seat 33, a tilting cylinder 34, a connecting rod 35, and a base plate 36;
[0097] Two base plates 36 are installed near the bottom left and right sides of the frame 202, respectively. The bottom of the upright support frame 31 is fixed to the top surface of the base plate 36. The pivot seat 33 is installed on the top surface of the support frame 31. One end of the pivot 32 is rotatably inserted into the pivot seat 33. The other end of the pivot 32 is connected to the left or right side of the frame 202. The frame 202 is suspended from the top surface of the two support frames 31 by the two pivots 32. The bottom surface of the frame 202 and the bottom surface of the base plate 204 are suspended and located above the top surface of the base plate 36.
[0098] One end of the connecting rod 35 is connected to the left or right side of the rear end face of the frame 202. The tilting cylinder 34 is located directly below the connecting rod 35. The bottom end of the tilting cylinder 34 is rotatably connected to the top surface of the base plate 36. The other end of the connecting rod 35 is movably connected to the upwardly extending output end of the tilting cylinder 34.
[0099] like Figure 4 As shown, when entering the slurry discharge and consolidation step, the two tilting cylinders 34 are activated, causing the output ends of the tilting cylinders 34 to retract downwards. Under the pulling action of the two connecting rods 35, the frame 202 rotates along the rotating shaft 32 and tilts backwards. At this time, each slurry discharge valve is opened, which can completely discharge the residual slurry in each mold cavity, thereby improving the effect of slurry discharge and consolidation, and thus improving the quality of the produced shell blank, seat ring blank and water channel blank.
[0100] After the residual slurry in each mold cavity is completely discharged, the tilting cylinder 34 is closed, the output end of the tilting cylinder 34 extends upward and resets, and pushes the frame 202 to rotate along the rotating shaft 32 through the two connecting rods 35 to reset.
[0101] Furthermore, the lifting device 6 includes a lifting motor 61, a lifting screw 62, a support plate 63, a guide column 64, and a lifting plate 65;
[0102] The lifting plate 65 is provided with a first internal threaded hole and a guide post mounting hole spaced apart from each other.
[0103] The rear end of the support plate 63 is fixed to the front right side of the frame 202; the lifting motor 61 is vertically installed on the top surface of the support plate 63.
[0104] The upper end of the vertical lifting screw 62 passes through the support plate 63 and is connected to the output end of the lifting motor 61; the lifting plate 65 is located below the support plate 63, and the lifting plate 65 is fitted onto the outer circumferential surface of the lifting screw 62 through the first internal thread hole;
[0105] The guide post 64 is located in front of the lifting screw 62. The upper end of the guide post 64 is fixed to the support plate 63. The lower end of the guide post 64 extends downward and passes through the guide post mounting hole. A gap is left between the outer peripheral surface of the guide post 64 and the inner wall surface of the guide post mounting hole.
[0106] The rotating device 7 is installed at the front end of the lifting plate 65.
[0107] like Figure 1As shown, the lifting motor 61 drives the lifting screw 62 to rotate, and drives the lifting plate 65 and the rotating device 7 to rise or fall along the guide column 64. This allows the other end of the robotic arm 9 to rise or fall between the upper mold 11 and the lower mold 12 of the outer shell, between the upper mold 13 and the lower mold 14 of the water channel, or between the upper mold 15 and the lower mold 16 of the seat ring. This can improve the positioning accuracy of the height of the robotic arm 9.
[0108] Furthermore, the rotating device 7 includes a rotating motor 71, a rotating column 72, and a mounting base 73;
[0109] The rear end face of the mounting base 73 is fixed to the front end of the lifting plate 65. The rotary motor 71 is mounted on the front end of the mounting base 73. The upper end of the rotating column 72 is rotatably inserted into the mounting base 73 from bottom to top. The output end of the rotary motor 71 is in transmission cooperation with the outer peripheral surface of the upper end of the rotating column 72. The lower end of the rotating column 72 extends downward and is exposed below the mounting base 73.
[0110] The robotic arm 9 is provided with two extension rods 91. One end of the two extension rods 91 is connected to the outer side of one end of the robotic arm 9, and the other end of the extension rods 91 is connected to the outer peripheral surface of the exposed rotating column 72.
[0111] like Figure 1 , Figure 4 and Figure 5 As shown, the rotary motor 71 drives the rotary column 72 to rotate, and drives the robotic arm 9 to rotate horizontally around the axis of the rotary column 72. This allows the other end of the robotic arm 9 to rotate and extend into the space between the open upper mold 11 and the lower mold 12 of the outer shell, the upper mold 13 and the lower mold 14 of the water channel, or the upper mold 15 and the lower mold 16 of the seat ring. The blanking plate 8 placed on the robotic arm 9 can then receive the demolded outer shell blank, water channel blank 10, or seat ring blank.
[0112] Furthermore, it also includes a lifting device 30;
[0113] The lifting device 30 includes a lifting motor 303, a transmission rod 306, two linkage rods 304, two mounting platforms 305, multiple screw elevators 301, and multiple lifting lead screws 302;
[0114] The two mounting platforms 305 are located on the left and right sides of the frame 202 respectively. The right or left side of the mounting platform 305 is fixed to the left or right side of the frame 202 respectively. The mounting platform 305 is located above the corresponding support frame 31.
[0115] The mounting platform 305 is provided with a plurality of second internal threaded holes arranged at intervals, and the support frame 31 is provided with a plurality of clearance holes, with the second internal threaded holes and the clearance holes aligned vertically.
[0116] The multiple screw elevators 301 are divided into two groups. The multiple screw elevators 301 in one group are installed on the top surface of the mounting platform 305 at intervals. The top end of the lifting screw 302 passes upward through the second internal thread hole and is connected to the bottom surface of the top beam 200. The outer peripheral surface of the lifting screw 302 is in transmission cooperation with the screw elevator 301. The bottom end of the lifting screw 302 extends downward and passes through the corresponding clearance hole. A gap is left between the outer peripheral surface of the lifting screw 302 and the clearance hole.
[0117] Two linkage rods 304 extending in the front-back direction are respectively mounted on the two mounting platforms 305; the output end of the lifting motor 303 is connected to one end of the two linkage rods 304 through the transmission rod 306, and each screw elevator 301 in the group is respectively engaged with the outer peripheral surface of the corresponding linkage rod 30.
[0118] like Figure 1 , Figure 4 and Figure 6 As shown, the lifting motor 303 drives multiple screw lifters 301 located on the left and right sides of the frame 202 to rotate synchronously through the transmission rod 306 and two linkage rods 304, thereby driving multiple lifting screws 302 to rotate, which in turn drives the top beam 200 to rise or fall, and then drives the toilet mold 1 to rise to open the mold or fall to close the mold through the mold closing cylinder 201, which has better lifting stability.
[0119] Furthermore, it also includes multiple locking pin devices 4;
[0120] The locking pin device 4 includes a pin plate 41, a pin rod 42, a locking pin cylinder 43, a locking pin plate 44, and a pin guide sleeve 45.
[0121] The frame 202 has two columns 2022 spaced apart on both the left and right sides, and the front and rear ends of the crossbeam 2021 are respectively connected to the two opposite surfaces of the two columns 2022.
[0122] One end of each of the two locking pin plates 44 is connected to two opposite surfaces of the two columns 2022, and the locking pin plates 44 are disposed near the top of the columns 2022;
[0123] The pin plate 41 is a vertical flat plate extending in the front-back direction, and the locking pin plate 44 includes two straight plates spaced apart from each other on the left and right, with a pin gap 441 between the two straight plates.
[0124] The top of the pin plate 41 is connected to the bottom surface of the top beam 200. The pin plate 41 and the pin gap 441 are aligned vertically. Both the pin plate 41 and the straight plate are provided with pin holes. The pin holes penetrate the surface of the pin plate 41 or the straight plate in the left-right direction. One end of the pin guide sleeve 45 is installed close to the edge of the pin hole of the straight plate located on the outer side, and the other end of the pin guide sleeve 45 extends outward.
[0125] The locking cylinder 43 is installed on the outside of the other end of the pin guide sleeve 45. The output end of the locking cylinder 43 is connected to one end of the pin rod 42. The other end of the pin rod 42 extends into the pin guide sleeve 45 and is close to the pin gap 441.
[0126] like Figure 2 , 4 As shown in Figure 6, when the mold closing cylinder 201 is activated, the output end of the mold closing cylinder 201 pushes the top surface of the upper mold 11 of the outer shell downward. Under the action of the reaction force, the middle part of the top beam 200 will deform upward, thereby causing the left and right sides of the top beam 200 to press down, which in turn drives the pin plate 41 to insert downward into the corresponding pin gap 441. At this time, the locking pin cylinder 43 is activated. The output end of the locking pin cylinder 43 extends out and pushes the other end of the pin rod 42 through the locking pin hole on the outer straight plate, the pin gap 441, the pin hole on the pin plate 41 and the locking pin hole on the inner straight plate in sequence, so that the top beam 200 and the frame 202 are locked and connected as one unit by the four locking pin devices 4.
[0127] Conversely, when the mold closing cylinder 201 is closed and depressurized, the output end of the mold closing cylinder 201 pulls the upper mold 11 of the outer shell upward, the middle part of the top beam 200 is reset, the locking pin cylinder 43 is closed, the output end of the locking pin cylinder 43 retracts and pulls the other end of the pin rod 42 back into the pin guide sleeve 45, the locking pin device 4 is unlocked, and the top beam 200 is disconnected from the frame 202 and separated.
[0128] Therefore, when the mold closing cylinder 201 is started, the column 2022 can share the pressure of the left and right sides of the top beam 200, thereby reducing the pressure on the lifting screw 302 caused by the left and right sides of the top beam 200, thus preventing the lifting screw 302 from deforming and improving the service life of the lifting screw 302.
[0129] Furthermore, the toilet mold 1 also includes a center-parting linkage mechanism 18;
[0130] The upper mold 13 of the waterway is symmetrically divided into the upper left mold 131 and the upper right mold 132 of the waterway;
[0131] The central linkage mechanism 18 includes two mold opening cylinders 181, two transmission chains 183, two mold opening motors 184, and multiple transmission wheels 182;
[0132] The two mold-opening motors 184 are respectively installed on the left and right sides of the lower mold 12 of the outer shell;
[0133] The multiple drive wheels 182 are divided into four groups, and a group of drive wheels 182 is installed at the front and rear of the upper left mold 131 of the waterway and at the front and rear of the upper right mold 132 of the waterway, respectively.
[0134] The outer peripheral surfaces of the plurality of transmission wheels 182 located in front of the upper left mold 131 of the waterway and the outer peripheral surfaces of the plurality of transmission wheels 182 located in front of the upper right mold 132 of the waterway respectively mesh with the inner surface of the upper half and the inner surface of the lower half of a transmission chain 183. The left and right ends of the transmission chain 183 are in transmission cooperation with the front output ends of the two mold opening motors 184.
[0135] The outer peripheral surfaces of the plurality of transmission wheels 182 located behind the upper left mold 131 of the waterway and the outer peripheral surfaces of the plurality of transmission wheels 182 located behind the upper right mold 132 of the waterway respectively mesh with the inner side of the upper half and the inner side of the lower half of another transmission chain 183. The left and right ends of this transmission chain 183 are connected to the rear output ends of the two mold opening motors 184.
[0136] One of the mold-opening cylinders 181 is fixed at the front of the upper left mold 131 of the water channel and the front of the upper right mold 132 of the water channel, respectively; the other mold-opening cylinder 181 is fixed at the rear of the upper left mold 131 of the water channel and the rear of the upper right mold 132 of the water channel, respectively.
[0137] like Figure 4 As shown, when it is necessary to separate the upper mold 13 of the waterway into the left and right halves, the two mold opening cylinders 181 start simultaneously and extend their respective slide rods. At the same time, the two mold opening motors 184 start synchronously and drive the four sets of transmission wheels 182 to rotate through the two transmission chains 183, thereby causing the upper left mold 131 of the waterway and the upper right mold 132 of the waterway to move away from each other and open the mold.
[0138] Conversely, when it is necessary to close the upper mold 13 of the waterway, the two mold-opening cylinders 181 close and retract their slide rods. At the same time, the two mold-opening motors 184 start synchronously and move in opposite directions, driving the four sets of transmission wheels 182 to rotate through the two transmission chains 183, causing the upper left mold 131 and the upper right mold 132 of the waterway to come together and close the mold. Figure 2 As shown.
[0139] This improves the smoothness of the opening and closing of the upper mold 13 in the waterway.
[0140] Furthermore, the upper waterway mold 13 is an upper concave mold, and the lower waterway mold 14 has an upper convex waterway mold 140 in the middle that matches the upper waterway mold 13.
[0141] The lower water channel mold 14 is provided with a mold frame 142. The mold frame 142 is an annular body extending along the edge of the lower water channel mold 14. The mold frame 142 surrounds the periphery of the upper convex water channel mold 140. An annular groove 141 is formed between the inner wall surface of the mold frame 142 and the outer peripheral surface of the upper convex water channel mold 140. The inner wall surface of the mold frame 142 is an inclined surface that slopes from bottom to top and outward.
[0142] The outer periphery of the upper mold 13 of the waterway is an inclined surface that slopes inward from top to bottom.
[0143] like Figure 4 As shown, the inner wall surface of the mold frame 142 is an inclined surface that slopes outward from bottom to top, and the outer peripheral surface of the upper mold 13 of the water channel is an inclined surface that slopes inward from top to bottom, matching the inner wall surface of the mold frame 142. When the upper mold 13 of the water channel and the lower mold 14 of the water channel are closed, the inner wall surface of the mold frame 142 can exert a better squeezing effect on the outer peripheral surface of the upper mold 13 of the water channel, thereby improving the tightness of the mold closing of the upper left mold 131 and the upper right mold 132 of the water channel.
[0144] Furthermore, the toilet mold 1 also includes a plurality of upper conical plates 191 and a plurality of lower conical plates 192;
[0145] The plurality of upper conical plates 191 and the plurality of lower conical plates 192 are corresponding one above the other;
[0146] The upper cone plate 191 is installed on the left or right side of the top of the outer shell upper mold 11, the left or right side of the top of the water channel upper mold 13, and the left or right side of the top of the seat ring upper mold 15.
[0147] The lower cone plate 192 is installed on the left or right side of the top of the outer shell lower mold 12, the left or right side of the top of the water channel lower mold 14, and the left or right side of the top of the seat ring lower mold 16.
[0148] The output end of the mold-locking cylinder 17 is provided with a mold-locking groove 171 that matches the outer peripheral surfaces of the upper cone plate 191 and the lower cone plate 192 that abut against each other.
[0149] like Figure 2 and Figure 4 As shown, when mold locking is required, the two output ends of the two corresponding mold locking cylinders 17 extend out and abut against the outer peripheral surfaces of the upper cone plate 191 and the lower cone plate 192 through the groove wall surfaces of the mold locking grooves 171 provided at the two output ends, thereby locking the closed upper mold 11 and lower mold 12 of the outer shell, the upper mold 13 and lower mold 14 of the water channel, or the upper mold 15 and lower mold 16 of the seat ring.
[0150] Preferably, when the tilting cylinder 34 retracts downward and pulls the frame 202 backward through the connecting plate 35, the angle between the plane containing the rear end face of the tilted frame 202 and the vertical plane is 6°-9°.
[0151] like Figure 5 As shown, by pulling down the corresponding connecting plate 35 by two tilting cylinders 34 respectively, the frame 202 is tilted backward by 6°-9°. This can not only completely discharge the residual slurry in each mold cavity and improve the effect of slurry discharge and consolidation, but also prevent the bottom edge of the base plate 204 from touching the ground at the installation site.
[0152] In summary, such as Figure 1-6 The embodiment of the present invention shown describes a grouting machine using a stacked toilet mold. This machine can complete the grouting of the toilet shell blank, seat ring blank, and water channel blank in one continuous operation at a single station. The seat ring blank, water channel blank 10, and shell blank can be sequentially removed via the cooperation of a robotic arm 9, lifting device 6, rotating device 7, and blank support plate 8. Adhesive can be applied manually or by spraying adhesive during blank removal to bond the shell blank, seat ring blank, and water channel blank 10 together. Each grouting machine using a stacked toilet mold can serve as a production unit to manufacture one toilet. Therefore, the grouting machine using a stacked toilet mold of the present invention is suitable for small-batch production, offering advantages such as convenient production switching and flexible production scheduling. It also features a compact structure and small footprint, resulting in good economic benefits.
[0153] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
