Description

Technical Field

[0001] The present invention relates to the technical field of dip molding, and specifically relates to a molding device for dip molding toy production. Background Art

[0002] Dip molding is a process used to make toys. The liquid plastic state material is poured into a mold, and then the mold is placed in a dip molding furnace and rotated for heating and molding to make a hollow or solid elastic product. During the dip molding process, many factors can affect the dip molding quality. For example, the unstable rotation speed of the mold, the non-coaxial rotation of the mold and the rotating shaft, and the uneven cooling of the mold can all cause the decline of dip molding quality.

[0003] Currently, the dip molding process has been widely used, but it still has many defects, specifically as follows: During the dip molding process, first, the liquid plastic state material is poured into the mold, and then the mold is placed on the bracket in the dip molding furnace, and then the motor drives the mold on the bracket to rotate to heat and mold the liquid plastic state material in the mold. During this process, when the motor has a reduced accuracy or fails after long-term use, the rotation speed of the motor will be unstable, which will in turn cause the rotation speed of the mold on the bracket to be unstable, resulting in uneven thickness of the dip molded product after molding, affecting the product quality. Moreover, when the rotation speed of the motor becomes unstable, it is generally difficult for the staff to detect it in time. Therefore, it will cause the problem of unqualified batch products. When the staff discovers that the rotation speed of the motor is unstable, they will immediately stop the motor. At this time, the liquid plastic state material that is not fully molded in the mold will be wasted or reworked, which is time-consuming and laborious. In addition, after the liquid plastic state material is rotationally heated and molded, the staff directly pulls it out of the dip molding furnace and puts it into water for cooling, which may cause defects in the molding of the dip molded product due to the sudden temperature drop.

[0004] In view of the above problems, a molding device for dip molding toy production is proposed. Summary of the Invention

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] To solve the technical problem that when the first motor 32 or the second motor 34 has a decrease in accuracy after long-term use or fails, the rotational speed of the first motor 32 or the second motor 34 is unstable, which in turn causes the rotational speeds of the bracket 7 and the forming assembly 8 to be unstable, resulting in uneven thickness of the dip-molded product after molding. For example, Figures 1 - 16 as shown, the following preferred technical solutions are provided: As Figure 1 shown, a molding device for dip-molded toy production includes a dip-molding furnace 1, which is used to heat the liquid plastic state material, facilitating subsequent molding. A placement rack 4 is arranged on the front side of the dip-molding furnace 1, and the placement rack 4 is used to support and limit the components. A collection bin 50 is placed at the bottom of the placement rack 4, which is used to collect the wastewater after the pre-cooling of the dip-molded product for subsequent recycling. A cooling water tank 40 is placed beside the placement rack 4. After the dip-molded product is pre-cooled, it is further cooled by the cooling water tank 40, which is beneficial to the dip-molding quality and prevents the phenomenon of molding defects due to sudden temperature drop. For example, Figure 1 and Figure 4 shown, a driving assembly 3 is fixedly arranged on the outer wall at the rear side of the dip-molding furnace 1, and a rotating assembly 2 is rotatably arranged through the side wall of the furnace cavity of the dip-molding furnace 1. The output shaft of the driving assembly 3 is fixedly connected to the rotating assembly 2. The driving assembly 3 drives the rotating assembly 2 to rotate, which is used to rotate and heat the liquid plastic state material for molding. For example, Figures 4 - 5 shown, an adapter assembly 10 is also fixedly arranged on the outer wall at the rear side of the dip-molding furnace 1. The output of the adapter assembly 10 is sleeved on the rotating assembly 2. The adapter assembly 10 is used to switch the power source in the driving assembly 3 to ensure that the rotating assembly 2 can rotate stably, which is beneficial to dip-molding and does not result in uneven thickness of the dip-molded product.

[0021] As Figure 1As shown in the figure, a steam generation chamber 20 is embedded inside the plasticizing furnace 1. During the use of the plasticizing furnace 1, the temperature is as high as 250°C - 280°C. The heat generated by the plasticizing furnace 1 is used to evaporate the water in the steam generation chamber 20 to generate steam. A water storage tank 30 is fixedly arranged on one outer wall of the plasticizing furnace 1. The steam generation chamber 20 is respectively communicated with the water storage tank 30 and the connection assembly 10 through air pipes. The steam in the steam generation chamber 20 will enter the water storage tank 30 and the connection assembly 10 through the air pipes respectively. When entering the water storage tank 30, the steam can pressurize and heat the water in the water storage tank 30 for subsequent pre-cooling of plasticized products, avoiding molding defects caused by too low water temperature and sudden temperature drop. When the steam enters the connection assembly 10, it can drive the connection assembly 10 to operate, for switching the power source in the drive assembly 3 to ensure that the rotating assembly 2 can rotate stably.

[0022] A pre-cooling assembly 5 and a transfer sliding seat 6 are respectively slidably arranged on the placement rack 4. The pre-cooling assembly 5 is used to pre-cool the plasticized products after heating and molding. The transfer sliding seat 6 is used to achieve the transfer effect. A bracket 7 is placed on the pre-cooling assembly 5, and several molding assemblies 8 are arranged on the bracket 7. Before plasticizing, first quantitatively add the liquid plastic state material into the molding assembly 8, then place the bracket 7 and the molding assembly 8 together on the rotating assembly 2, and then drive the rotating assembly 2, the bracket 7 and the molding assembly 8 to rotate through the drive assembly 3, and then cooperate with the heating effect of the plasticizing furnace 1 to rotate and heat the liquid plastic state material in the molding assembly 8 for molding, as Figures 2 - 3 As shown in the figure, a transmission assembly 9 is arranged at the bottom of the pre-cooling assembly 5, and the transmission assembly 9 is meshed with the pre-cooling assembly 5, as Figure 10 As shown in the figure, the transmission assembly 9 is communicated with the water storage tank 30 through a water pipe.

[0023] After rotational heating and molding, it enters the annealing furnace for shaping. After shaping, the bracket 7 and the molding assembly 8 are taken out and placed on the pre-cooling assembly 5. Since the steam in the steam generation chamber 20 enters the water storage tank 30 through the air pipe, the steam will pressurize and heat the water in the water storage tank 30. The pressurized warm water will enter the transmission assembly 9 through the water pipe and drive the transmission assembly 9 to operate. Also, since the transmission assembly 9 is meshed with the pre-cooling assembly 5, when the transmission assembly 9 operates, it will drive the molding assembly 8 to rotate through the pre-cooling assembly 5, which is beneficial to the efficiency of uniform heat dissipation. And the warm water flowing out from the transmission assembly 9 will be sprayed on the molding assembly 8, further improving the efficiency of uniform heat dissipation without the situation of sudden temperature drop.

[0024] As Figure 4As shown in the figure, the dipping rubber furnace 1 includes a furnace body 11 and a water level gauge 12 embedded on the outer wall of one side of the furnace body 11. The water level gauge 12 is communicated with the steam generating chamber 20. The water level gauge 12 is provided to monitor the water level in the steam generating chamber 20 and prevent the subsequent precooling effect from being affected due to too low water level and less steam generation.

[0025] As Figures 6 - 7 shown in the figure, the rotating assembly 2 includes a rotating shaft 21 penetrating and rotatably installed on the side wall of the furnace cavity of the dipping rubber furnace 1. One end of the rotating shaft 21 in the furnace cavity of the dipping rubber furnace 1 is fixedly installed with a clamping jaw 22. The bracket 7 can be placed on the clamping jaw 22. A limiting groove 23 is opened at one end of the rotating shaft 21 close to the driving assembly 3. A telescopic shaft 24 is slidably installed inside the limiting groove 23. One end of the telescopic shaft 24 away from the limiting groove 23 is fixedly installed with a first transmission gear 25. A number of guiding blocks 26 are correspondingly fixedly installed on the tooth portions of the outer side walls on both sides of the first transmission gear 25. By default, the telescopic shaft 24 is inserted inside the limiting groove 23. When the first transmission gear 25 rotates, the rotating shaft 21 and the clamping jaw 22 can be driven to rotate under the cooperation of the limiting groove 23 and the telescopic shaft 24, so as to drive the bracket 7 and the forming assembly 8 to rotate in the furnace cavity of the dipping rubber furnace 1.

[0026] As Figures 4 - 5 and Figure 7 shown in the figure, the driving assembly 3 includes a mounting frame 31 fixedly installed on the outer wall at the rear side of the furnace body 11. A first motor 32 and a second motor 34 are respectively fixedly installed on the mounting frame 31. The first motor 32 and the second motor 34 can provide power output for realizing the rotating heating operation. As Figure 5 shown in the figure, the first motor 32 and the second motor 34 are arranged in a staggered manner. A first driving gear 33 is fixedly installed on the output shaft of the first motor 32. A number of guiding blocks 26 are correspondingly fixedly installed on the tooth portions of the side wall of the first driving gear 33 facing away from the first motor 32. A second driving gear 35 is fixedly installed on the output shaft of the second motor 34. A number of guiding blocks 26 are correspondingly fixedly installed on the tooth portions of the side wall of the second driving gear 35 facing the second motor 34. The first transmission gear 25 can be meshed with the first driving gear 33 and the second driving gear 35 respectively. The guiding blocks 26 are arranged in an arc shape. When the first transmission gear 25 is meshed with the first driving gear 33 or the second driving gear 35, it can play a guiding role to prevent the occurrence of gear jamming and avoid damage to components.

[0027] As Figures 5 - 7As shown, when the rotational speed of the first motor 32 becomes unstable, the steam in the steam generation chamber 20 is discharged into the connection assembly 10 through a gas pipe, causing the connection assembly 10 to start operating and driving the rotation shaft 21 to move, disengaging the first transmission gear 25 from the first driving gear 33 and releasing the meshing relationship. At the same time, the first transmission gear 25 forms a meshing relationship with the second driving gear 35, and the second motor 34 provides power output for rotational heating operations. At this time, without affecting rotational heating and forming, the first motor 32 can be repaired and used as a standby drive source after the repair. When the rotational speed of the second motor 34 becomes unstable, the steam drives the connection assembly 10 to start operating again and drives the rotation shaft 21 to move in the reverse direction, disengaging the first transmission gear 25 from the second driving gear 35 and releasing the meshing relationship. At the same time, the first transmission gear 25 re - forms a meshing relationship with the first driving gear 33, and the first motor 32 provides power output again for rotational heating operations. Through the above settings, when the rotational speed of the first motor 32 or the second motor 34 becomes unstable, a switch can be made immediately to ensure that the rotational speed remains stable during rotational heating and forming, which is beneficial to achieving a better forming effect.

[0028] As Figure 6 and Figures 8 - 9 shown, the connection assembly 10 includes a housing 101 fixedly installed on the rear outer wall of the furnace body 11. The interior of the housing 101 is respectively provided with an installation groove 102, a first air chamber 103, and a second air chamber 104. The installation groove 102 is respectively communicated with the first air chamber 103 and the second air chamber 104. On the bottom surface of the inner cavity of the installation groove 102, a first groove 105 and a second groove 106 are symmetrically provided respectively. In the inner cavities of the first groove 105 and the second groove 106, clamping columns 140 are respectively slidably installed. The two clamping columns 140 are elastically connected to the side walls of the inner cavities of the first groove 105 and the second groove 106 through first springs 150 respectively. On the top surface of the inner cavity of the installation groove 102, a first air outlet 107 and a second air outlet 108 are symmetrically provided respectively. A piston plate 110 is slidably installed in the inner cavity of the installation groove 102. On the bottom surface of the piston plate 110, a pair of clamping grooves 130 are symmetrically provided, and a clamping connection relationship can be formed between the clamping grooves 130 and the clamping columns 140. An L - shaped support arm 120 is fixedly installed on the side wall of the piston plate 110. The L - shaped support arm 120 is slidably installed through the side wall of the housing 101. As Figure 6 shown, at the distal end of the L - shaped support arm 120, a collar 160 is fixedly installed. The collar 160 is sleeved on the circumferential outer wall of the rotation shaft 21, and the rotation shaft 21 can rotate on the collar 160 but cannot axially move on the collar 160. An electronic air valve 109 is fixedly installed on the side wall of the housing 101. The electronic air valve 109 is respectively communicated with the first air chamber 103 and the second air chamber 104 through gas pipes.

[0029] Specifically, before slush molding, the slush molding furnace 1 is preheated to 250°C - 280°C. During this period, the heat generated by the slush molding furnace 1 is used to evaporate the water in the steam generation chamber 20 to generate steam. Then, the bracket 7 and the molding assembly 8 are placed on the transfer slide 6. The operator opens the molding assembly 8 and quantitatively adds the liquid plastic state material into the interior of the molding assembly 8. After the filling is completed, the operator closes the molding assembly 8 and places the bracket 7 and the molding assembly 8 on the clamping jaw 22. Then, the first motor 32 is started to operate. The first motor 32 drives the transmission gear one 25 and the telescopic shaft 24 to rotate synchronously through the first driving gear 33. Under the combined action of the limiting groove 23 and the telescopic shaft 24, the rotating shaft 21 and the clamping jaw 22 can be driven to rotate, thereby driving the bracket 7 and the molding assembly 8 to rotate in the furnace cavity of the slush molding furnace 1, and the liquid plastic state material inside the molding assembly 8 is rotationally heated and molded.

[0030] As Figure 8 shown, when the first motor 32 has unstable rotation speed during the rotational heating process, the steam in the steam generation chamber 20 is discharged into the second air chamber 104 through the air pipe and the electronic air valve 109. Since the piston plate 110 blocks the second air outlet 108 at this time, the steam pressure will generate a thrust on the piston plate 110. As Figure 9 shown, since the top of the clamping column 140 is arranged in an arc shape, when the thrust generated by the steam pressure on the piston plate 110 reaches a certain degree, the clamping column 140 will be pressed into the second groove 106, and the clamping column 140 will be pulled out of the clamping groove 130, releasing the limiting relationship. At this time, the piston plate 110 can slide inside the installation groove 102. When the piston plate 110 slides, when the other one is above the first groove 105 of the clamping groove 130, under the elastic force of the first spring 150, the clamping column 140 pops up upward and inserts into the clamping groove 130 to position the piston plate 110 and prevent the piston plate 110 from sliding randomly in the installation groove 102. After the piston plate 110 is positioned, the second air outlet 108 is in communication with the outside, and the excess steam will be discharged through the second air outlet 108. At this time, the first air outlet 107 is in a blocked state.

[0031] As Figure 5 and Figure 7As shown, since the rotating shaft 21 can rotate on the collar 160, and the rotating shaft 21 cannot move axially on the collar 160, during the movement of the piston plate 110, the rotating shaft 21 is driven to move by the L-shaped arm 120 and the collar 160, so that the transmission gear 1 25 is disengaged from the first driving gear 33, and the meshing relationship is released. At the same time, the transmission gear 1 25 is meshed with the second driving gear 35, and the second motor 34 provides power output for realizing the rotary heating operation. At this time, the first motor 32 can also be repaired without affecting the rotary heating molding. After the overhaul of the machine 32 is completed, it serves as a backup driving source; when the speed of the second motor 34 is unstable, the steam is discharged into the first air chamber 103 through the air pipe and the electronic air valve 109, and the steam pressure is used again to push the piston plate 110 to move in the opposite direction and position it in the installation groove 102. During the reverse movement of the piston plate 110, the rotating shaft 21 is driven to move in the opposite direction, and the transmission gear 25 is disengaged from the second driving gear 35, and the meshing relationship is released. At the same time, the transmission gear 25 re-engages with the first driving gear 33, and the first motor 32 provides power output again to realize the rotary heating operation.

[0032] When it is detected that the speed of the first motor 32 or the second motor 34 is unstable, through the above settings, the steam pressure can be used to automatically switch the power source to ensure that the speed remains stable during the rotary heating molding process, and prevent the problem of uneven thickness of the enamel products caused by unstable speed, which is conducive to achieving better molding effects. In addition, even if the staff does not discover it in time, it will not cause the problem of unqualified batch products, nor will it cause waste of raw materials. There is no need to stop the machine to switch the power supply, which achieves seamless connection and improves work efficiency.

[0033] In order to solve the technical problem that after the liquid plastic material is rotated and heated to form, the staff directly pulls it out of the enameling furnace 1 and puts it into water for cooling, and the enameling product forming will be defective due to the sudden drop in temperature, such as Figures 10 - 16 As shown, the following preferred technical solutions are provided: like Figure 10 As shown, the placement rack 4 includes a rack body 41 , on which two limit rods 42 are fixedly mounted, and the precooling assembly 5 and the transfer slide 6 are slidably mounted on the two limit rods 42 .

[0034] like Figures 11 - 12As shown, the precooling component 5 includes a slide 51, on which two through grooves 52 are provided, and two limit rods 42 are slidably arranged inside the two through grooves 52, and a clearance groove 53 is provided on the top surface of the slide 51, and a plurality of load-bearing blocks 54 are fixedly installed on the bottom surface of the inner cavity of the clearance groove 53, respectively. When the bracket 7 is placed in the clearance groove 53, the load-bearing block 54 can support the bracket 7, and a positioning groove 55 is further provided on the top surface of the slide 51. The setting of the positioning groove 55 facilitates the bracket 7 to be placed on the load-bearing block 54 at a specific angle, and the bracket 7 is fixedly arranged at the fixed position. A position sensor 56 is embedded and fixedly installed on the load-bearing block 54 opposite to the position of the positioning groove 55, and is used to determine whether the bracket 7 is placed at the specified position. A plurality of rotating drums 57 are rotatably installed through the bottom surface of the inner cavity of the positioning groove 53, and a tray 58 is fixedly installed on the top surface of each rotating drum 57. A transmission gear 2 59 is fixedly installed on the bottom surface of the rotating drum 57. When the bracket 7 is placed at the specified position, the molding component 8 just falls on the tray 58, which supports the molding component 8. The transmission component 9 can drive the rotating drum 57 and the tray 58 to rotate synchronously through the transmission gear 2 59.

[0035] like Figure 12 As shown, the bracket 7 includes a disk body 71 and a positioning block 72 fixedly installed on the circumferential side wall of the disk body 71. The positioning block 72 and the positioning groove 55 are matched to ensure that the bracket 7 is placed in the specified position. A handle 73 is fixedly installed on the top surface of the disk body 71. The setting of the handle 73 makes it easy for the operator to take the bracket 7.

[0036] like Figure 13 and Figure 15 As shown, the molding assembly 8 includes a load-bearing frame 81 fixedly mounted on the plate 71, a mold 82 is rotatably arranged on the load-bearing frame 81, a liquid plastic material is injected into the mold 82, and a plurality of connecting rods 83 are vertically fixedly mounted on the outer wall of the mold 82, such as Figure 14 As shown, an annular groove 84 is provided on the bottom surface of the load-bearing frame 81, and a slider 85 is provided in the inner cavity of the annular groove 84. The slider 85 is slidably installed on the bottom surface of the inner cavity of the annular groove 84 through a T-shaped block 86. The connecting rod 83 is slidably installed on the slider 85, and the connecting rod 83 can rotate on the slider 85. An annular friction surface 87 is fixedly provided in the inner cavity of the annular groove 84, and a pair of friction rods 88 are fixedly installed on the top of the connecting rod 83. The top of the connecting rod 83 and the slider 85 are elastically connected through a spring 89.

[0037] like Figure 11 and Figure 15As shown, the transmission assembly 9 includes a pair of L-shaped mounting plates 91 fixedly installed on the bottom surface of the sliding table 51. A protective housing 92 is fixedly installed on the two L-shaped mounting plates 91. An impeller 93 is rotatably installed inside the protective housing 92. A transmission shaft 94 is fixedly installed on the top surface of the impeller 93, and the transmission shaft 94 penetrates and is rotatably arranged on the top surface of the protective housing 92. A third driving gear 95 is fixedly installed at the distal end of the transmission shaft 94. The third driving gear 95 is meshed and connected with two of the second transmission gears 59 respectively. A water valve 96 is fixedly installed and communicated on one outer wall of the protective housing 92. A pair of spray heads 97 are fixedly installed on the top surface of the sliding table 51, and the two spray heads 97 are respectively communicated with the water valve 96 through water pipes. The protective housing 92 is communicated with the water storage tank 30 through a water pipe.

[0038] Specifically, as Figures 13 - 14 shown, since there is opposite magnetism between the top end of the connecting rod 83 and the slider 85, the top end of the connecting rod 83 and the slider 85 attract each other. Therefore, by default, the lower end of the friction rod 88 will be in tight contact with the annular friction surface 87. Using the frictional force between the friction rod 88 and the annular friction surface 87, the braking effect is achieved, so that the connecting rod 83, the slider 85 and the T-shaped block 86 will not slide in the inner cavity of the annular groove 84, and further the mold 82 will not rotate in the inner cavity of the annular groove 84, preventing the problem of poor forming quality of the plasticized product due to the self-rotation of the mold 82 during the rotary heating process.

[0039] After the liquid plastic state material inside the mold 82 is rotationally heated and formed, it enters the loop furnace for shaping. After shaping, the bracket 7 and the forming assembly 8 are removed from the clamping jaw 22 and placed on the load-bearing block 54. When the bracket 7 is placed on the load-bearing block 54, the bottom of the mold 82 will first fall on the tray 58. When the bracket 7 is completely placed on the load-bearing block 54, as Figure 16 shown, the tray 58 will jack up the mold 82 by a certain distance. At this time, the lower end of the friction rod 88 will be separated from the annular friction surface 87, and the braking effect disappears, enabling the connecting rod 83, the slider 85 and the T-shaped block 86 to slide in the inner cavity of the annular groove 84, and further enabling the mold 82 to rotate in the inner cavity of the annular groove 84.

[0040] As Figures 11 - 12As shown, since the steam in the steam generation chamber 20 enters the water storage tank 30 through the trachea, the steam will pressurize and heat the water in the water storage tank 30. When the position sensor 56 determines that the bracket 7 is completely placed in the specified position, the pressurized warm water will enter the protective shell 92 through the water pipe and drive the impeller 93 to rotate. Since the third driving gear 95 is meshed with the second transmission gear 59, when the impeller 93 rotates, it will drive the rotating cylinder 57 and the tray 58 to rotate through the transmission shaft 94 and the third driving gear 95. Also, since the mold 82 can rotate in the inner cavity of the annular groove 84 at this time, the tray 58 can drive the mold 82 to rotate synchronously to disturb the surrounding air flow and achieve uniform heat dissipation, realizing the pre-cooling effect. At the same time, as Figure 15 shown, the warm water flowing through the impeller 93 will enter the nozzle 97 through the water valve 96 and the water pipe, and then be sprayed from the nozzle 97 onto the mold 82. Since the mold 82 is rotating during the spraying process of the warm water, uniform spraying can be achieved, further improving the uniform heat dissipation efficiency. At this time, the staff can use the time gap of pre-cooling to inject the liquid plastic state material into the next forming component 8 for the next use. When the staff puts the forming component 8 into the dipping furnace 1, then the bracket 7 and the forming component 8 are removed from the load-bearing block 54 and put into the cooling water tank 40 for complete cooling and forming.

[0041] As Figure 14 shown, when the bracket 7 and the forming component 8 are removed from the load-bearing block 54, under the elastic force of the second spring 89, the lower end of the friction rod 88 will be tightly pressed against the annular friction surface 87 again to achieve the braking effect, and once again make the connecting rod 83, the slider 85 and the T-shaped block 86 not slide in the inner cavity of the annular groove 84, and further make the mold 82 not rotate in the inner cavity of the annular groove 84, preventing the problem of poor forming quality of the dipped rubber products caused by the self-rotation of the mold 82 during the rotary heating process.

[0042] Currently, after the dipped rubber products are rotationally heated and formed, they will enter the loop furnace for shaping. However, the actual situation is that even after entering the loop furnace for shaping and then being put into the cooling water tank 40 for complete cooling and forming, there may still be problems with poor forming quality caused by sudden temperature drop. Through the above settings, using the steam pressure generated by the heat of the dipping furnace 1 to drive the transmission component 9 and the pre-cooling component 5 to operate, and then drive the mold 82 to rotate self, disturbing the surrounding air flow and achieving uniform heat dissipation. At the same time, the warm water can also be evenly sprayed on the mold 82, further improving the uniform heat dissipation efficiency and the yield rate of the dipped rubber products without the situation of sudden temperature drop.
