Description

Technical Field

[0001] The present invention relates to the technical field of plastic product molds, and particularly to a mold for rapid demolding in the molding of plastic products of coffee machines. Background Art

[0002] The molding mold for plastic products of coffee machines is a tool specifically used for producing plastic components of coffee machines. The molding mold for plastic products of coffee machines usually consists of a fixed mold and a movable mold. Among them, the fixed mold is fixed on the fixed plate of the injection molding machine, and the movable mold is installed on the moving plate of the injection molding machine. The inside of the mold is provided with a cavity corresponding to the shape of the coffee machine component, as well as a gate and a runner system for the plastic melt to enter the cavity.

[0003] After retrieval, a rapid injection molding mold for plastic products according to CN220638764U disclosed by the publication number, when the cavity and the core are closed, the acting force formed by the closing mold squeezes the demolding capsule inside the mounting hole, causing the demolding capsule to rupture and flow out the demolding agent inside the demolding capsule, so as to facilitate the demolding of the plastic product when the mold is opened. In addition, the demolding capsule can be made of the same material as the plastic product. During the injection molding process, affected by the temperature of the molten plastic, the residue of the demolding capsule can be dissolved into the molten plastic, thus becoming part of the product material and reducing the defective part of the product. However, in actual use, the following deficiencies still exist in this solution: In the molding process of plastic products of coffee machines, the use of the mold is crucial, which is directly related to the precision, quality and production efficiency of the products. However, in actual operation, some plastic products with complex shapes or special materials are often encountered. These products are often difficult to be demolded smoothly due to the large friction force with the surface of the mold. To solve this problem, the traditional method is to apply a layer of grease on the inner surface of the mold to reduce the friction coefficient between the mold and the product, so as to ensure the smooth demolding. However, this demolding method has obvious deficiencies, that is, it needs to be applied manually, which is not only cumbersome and inefficient in operation, but also uneven application may affect the demolding effect and surface quality of the product.

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0021] The present invention provides a mold for rapid demolding in the molding of coffee machine plastic products. Refer to Figures 1 - 9 As shown in the figure, it includes a fixed mold 1 and a movable mold 2. Positioning rods 21 are fixedly installed at the four corners on the side of the movable mold 2, and positioning grooves 22 adapted to the positioning rods 21 are provided at the four corners on the side of the fixed mold 1. A molding component is arranged on the opposite side surfaces of the fixed mold 1 and the movable mold 2, a spraying component is arranged on the movable mold 2, and a feeding component is arranged between the spraying component and the movable mold 2; Among them, the spraying component includes a support arm 41 fixedly installed on the side of the movable mold 2. A rotating seat 42 is rotatably installed at the end of the support arm 41. A torsion spring 43 is sleeved at the end of the support arm 41, and both ends of the torsion spring 43 are fixedly connected to the support arm 41 and the rotating seat 42 respectively. A connecting rod 44 is fixedly installed on the outer wall of the rotating seat 42. A connecting plate 45 is fixedly installed at the bottom end of the connecting rod 44. A plurality of nozzles 46 are arranged on the side of the connecting plate 45. The plurality of nozzles 46 are arranged in a circular array on the side of the connecting plate 45. The plurality of nozzles 46 are communicated through a conduit 54. A fixed rod 47 corresponding to the connecting rod 44 is fixedly installed on the side of the fixed mold 1. An inclined rod 48 is fixedly installed at the end of the fixed rod 47 away from the fixed mold 1. The inclined rod 48 is inclined towards the side close to the movable mold 2. A horizontal rod 49 is fixedly installed at the end of the inclined rod 48; The feeding component includes a liquid guide bladder 51 fixedly installed on the side of the movable mold 2. Two spring telescopic rods 52 are fixedly installed at the positions on both sides of the liquid guide bladder 51 on the side of the movable mold 2. A pressing plate 53 is fixedly installed at the telescopic ends of the two spring telescopic rods 52. The pressing plate 53 is fixedly connected to the end of the liquid guide bladder 51. A liquid inlet pipe 55 is penetrated through the liquid guide bladder 51. The end of the conduit 54 away from the nozzle 46 is communicated with the liquid guide bladder 51. One-way valves with opposite flow directions are installed inside the conduit 54 and the liquid inlet pipe 55; As the moving mold 2 moves away from the fixed mold 1, the connecting rod 44 can slide along the fixed rod 47 and enter the inclined rod 48. Under the action of the inclination of the inclined rod 48 and the torsion spring 43, the rotating seat 42 can rotate along the support arm 41. When the connecting rod 44 slides to the position of the horizontal rod 49, the nozzle 46 on the connecting plate 45 can rotate to a position opposite to the molding assembly. When used again, when the moving mold 2 moves towards the fixed mold 1, the connecting plate 45 can slide from the horizontal rod 49 to the inclined rod 48 and finally slide onto the fixed rod 47. During this process, the rotating seat 42 can be reversed, so that the connecting plate 45 rotates out between the moving mold 2 and the fixed mold 1. As the moving mold 2 continues to move, the molding operation of the coffee machine plastic product can be continued.

[0022] See Figure 2 , Figure 3 , Figure 4 , Figure 6 , the molding assembly includes four guide grooves 31 symmetrically opened on the side of the moving mold 2. Guide blocks 32 are slidably installed on the inner walls of the four guide grooves 31. Molding modules 33 are fixedly installed on the sides of the two guide blocks 32 on the same side. A first spring 34 is fixedly installed between the side of the guide block 32 and the inner wall of the guide groove 31. A molding head 35 is fixedly installed at the position between the two molding modules 33 on the side of the moving mold 2. Molding cavities 36 corresponding to the molding head 35 are opened on the sides of the two molding modules 33. A mold groove 39 corresponding to the two molding modules 33 is opened on the side of the fixed mold 1. An injection nozzle 311 is provided on the inner wall of the mold groove 39. A ejector rod 312 is provided on the molding head 35; An insertion opening 37 is opened on the side of the molding module 33. A relief groove 38 corresponding to the insertion opening 37 is opened on the side of the moving mold 2. Two guide rods 310 corresponding to the insertion opening 37 are symmetrically and fixedly installed on the inner wall of the mold groove 39. The two guide rods 310 are inclined, and the ends of the two guide rods 310 away from the mold groove 39 are close to each other; In the initial state, the fixed mold 1 and the movable mold 2 are in a separated state. When processing the plastic products of the coffee machine, the moving plate of the injection molding machine can be opened to drive the movable mold 2 to move towards the fixed mold 1. During the movement of the movable mold 2, the socket 37 on the molding module 33 can be opposite to the guide rod 310 in the mold groove 39, and as the movable mold 2 moves, the guide rod 310 can enter the socket 37. Since both the guide rod 310 and the socket 37 are inclined, with the movement of the movable mold 2, under the guiding action of the guide rod 310, the two molding modules 33 can slide along the guide groove 31 through the guiding block 32, making the two molding modules 33 approach each other. As the movable mold 2 continues to move, the two molding modules 33 can enter the mold groove 39 on the fixed mold 1 and complete the mold closing in the mold groove 39. At this time, the end of the guide rod 310 can enter the relief groove 38, and the molding head 35 is located in the molding cavity 36 between the two molding modules 33, and the injection nozzle 311 can communicate with the molding cavity 36. Opening the injection nozzle 311 can inject the raw material into the molding cavity 36, and after cooling, the demolding operation can be carried out; after the raw material is molded in the molding cavity 36, at this time, the molded plastic products of the coffee machine can be located in the molding head 35 and the molding cavity 36. Starting the reverse movement of the moving plate, the movable mold 2 can move away from the fixed mold 1. During the process of the molding module 33 moving out of the mold groove 39, it can slide along the guide rod 310, making the two molding modules 33 move away from each other from the mold closing state. When the two molding modules 33 are completely separated, the ejector rod 312 slides out of the molding head 35 to eject the plastic products of the coffee machine on the molding head 35 for blanking.

[0023] See Figure 5 , Figure 8 , Figure 9 , a control component adapted to the pressing plate 53 is provided at one end of the movable mold 2 away from the fixed mold 1. The control component includes a driving roller one 61 rotatably installed on the side of the movable mold 2, a driving roller two 62 rotatably installed on the side of the movable mold 2 corresponding to the driving roller one 61. A speed regulating mechanism is provided between the driving roller one 61 and the driving roller two 62. A one-way bearing 63 is sleeved on the outer wall of the end of the driving roller one 61, a transmission gear ring 64 is sleeved on the outer wall of the one-way bearing 63. A guiding port 65 is opened on the side of the movable mold 2. A support rod 66 is fixedly installed on the side of the molding module 33, and a driving rack 67 meshing with the transmission gear ring 64 is fixedly installed at the end of the support rod 66 passing through the guiding port 65. A turntable 68 is fixedly installed at the end of the driving roller two 62. A support rod 69 is fixedly installed at the end of the pressing plate 53, and a V-shaped transmission plate 610 adapted to the turntable 68 is fixedly installed at the end of the support rod 69. An adjusting screw 611 is penetrated through the side edge position of the turntable 68, and a transmission ball head 612 corresponding to the V-shaped transmission plate 610 is rotatably installed at the end of the adjusting screw 611; When the forming module 33 is opened to the end of the guiding groove 31, the support rod 66 on its side can slide along the guiding port 65 and drive the driving rack 67 to slide, thereby driving the transmission gear ring 64 to rotate. This rotation direction is the locking direction of the one-way bearing 63. Therefore, the first transmission roller 61 can be driven to rotate by a certain angle. When the first transmission roller 61 rotates, it can drive the second transmission roller 62 to rotate through the speed regulating mechanism, so that the second transmission roller 62 rotates by a certain angle. When the second transmission roller 62 rotates, it can drive the turntable 68 to rotate. During the process of the two forming modules 33 approaching and closing, when the driving rack 67 drives the transmission gear ring 64 to rotate, this rotation direction is the free state of the one-way bearing 63. Therefore, the first transmission roller 61 cannot be driven to rotate. The staff can set the spraying of the mold release agent through the speed regulating mechanism. As the forming module 33 continuously opens and closes, when the set number of times of spraying the mold release agent is reached, at this time, the adjusting screw 611 on the turntable 68 and the transmission ball head 612 can rotate past the V-shaped transmission plate 610 at the end of the support rod 69 on the pressing plate 53, and drive the V-shaped transmission plate 610 to slide, thereby driving the pressing plate 53 to press and reset through the spring telescopic rod 52, so that the liquid guide bladder 51 on the pressing plate 53 is compressed and stretched. When the liquid guide bladder 51 is compressed, since one-way valves with opposite flow directions are installed in the conduit 54 and the liquid inlet pipe 55, the mold release agent in the liquid guide bladder 51 can enter the nozzle 46 along the conduit 54 and be sprayed onto the forming head 35. During the stretching process of the liquid guide bladder 51, the mold release agent can be pumped into the liquid guide bladder 51 through the liquid inlet pipe 55; if it is necessary to adjust the spraying measurement of the mold release agent, the adjusting screw 611 can be rotated to adjust the position of the transmission ball head 612. When it passes through the V-shaped transmission plate 610, the V-shaped transmission plate 610 is pushed to different positions, so as to control the compression degree of the liquid guide bladder 51, thereby realizing the adjustment of the spraying measurement of the mold release agent.

[0024] The speed regulating mechanism includes a connecting screw rod 71 rotatably installed on the side of the moving mold 2 between the first transmission roller 61 and the second transmission roller 62. A guiding rod 72 is fixedly installed at a position below the connecting screw rod 71 on the side of the moving mold 2. The outer wall of the connecting screw rod 71 is screwed with an adjusting disc 73, and the adjusting disc 73 is slidably connected with the guiding rod 72. A transmission wheel 74 is rotatably sleeved on the outer wall of the adjusting disc 73; The staff can adjust the spraying of the demolding agent corresponding to the molding times of the injection molded products. When adjusting, the connecting screw rod 71 can be rotated. The connecting screw rod 71 is screwed to the adjusting disc 73, and the adjusting disc 73 is slidably connected to the guide rod 72. Therefore, when the connecting screw rod 71 rotates, it can drive the adjusting disc 73 to slide along the guide rod 72, so that the transmission wheel 74 adjusts its position between the first transmission roller 61 and the second transmission roller 62. The first transmission roller 61 and the second transmission roller 62 are arranged in a frustum shape and are oppositely arranged. Therefore, by adjusting the position of the transmission wheel 74, the transmission ratio between the first transmission roller 61 and the second transmission roller 62 can be changed, so as to change the single rotation angle of the turntable 68, and thus spray the demolding agent once corresponding to different demolding times, ensuring that the demolding agent can be automatically sprayed without manual operation.

[0025] The specific working principle of the present invention is as follows: In use, in the initial state, the fixed mold 1 and the movable mold 2 are in a separated state. If it is necessary to process the plastic products of the coffee machine, the moving plate of the injection molding machine can be opened to drive the movable mold 2 to move towards the fixed mold 1. During the movement of the movable mold 2, the socket 37 on the molding module 33 can be opposite to the guide rod 310 in the mold groove 39, and as the movable mold 2 moves, the guide rod 310 can enter the socket 37. Since both the guide rod 310 and the socket 37 are inclined, as the movable mold 2 moves, under the guiding action of the guide rod 310, the two molding modules 33 can slide along the guide groove 31 through the guide block 32, so that the two molding modules 33 approach each other. As the movable mold 2 continues to move, the two molding modules 33 can enter the mold groove 39 on the fixed mold 1 and can complete the mold closing in the mold groove 39. At this time, the end of the guide rod 310 can enter the relief groove 38, and the molding head 35 is located in the molding cavity 36 between the two molding modules 33, and the injection nozzle 311 can communicate with the molding cavity 36. Opening the injection nozzle 311 can inject the raw material into the molding cavity 36, and after cooling, the demolding operation can be carried out. At the same time, when the movable mold 2 moves towards the fixed mold 1, the connecting plate 45 can slide from the horizontal rod 49 to the inclined rod 48 and finally slide to the fixed rod 47. During this process, the rotating seat 42 can reverse, so that the connecting plate 45 rotates out between the movable mold 2 and the fixed mold 1 to avoid affecting the normal mold closing of the fixed mold 1 and the movable mold 2; After the raw material is formed in the forming cavity 36, at this time, the formed plastic coffee machine product can be located in the forming head 35 and the forming cavity 36. Then, start the moving plate to move in the reverse direction. The moving die 2 can move and separate from the fixed die 1. During the process of the forming module 33 moving out of the die groove 39, it can slide along the guide rod 310, so that the two forming modules 33 move away from each other from the state of mold clamping. As the moving die 2 moves, the connecting rod 44 can slide along the fixed rod 47. During the separation process of the two forming modules 33, the connecting rod 44 can slide along the fixed rod 47 and enter the inclined rod 48. Under the action of the inclination of the inclined rod 48 and the torsion spring 43, the rotating seat 42 can rotate along the support arm 41. When the connecting rod 44 slides to the position of the horizontal rod 49, the nozzle 46 on the connecting plate 45 can rotate to the position opposite to the forming head 35. At this time, the two forming modules 33 are completely separated, and the forming head 35 and the plastic coffee machine product on it leak out. The ejector rod 312 slides out of the forming head 35 to eject the plastic coffee machine product on the forming head 35 for blanking. The working principle and connection method of the ejector rod 312 are mature existing technologies and will not be elaborated here; When the forming module 33 opens to the end of the guide groove 31, the support rod 66 on its side can slide along the guide port 65 and drive the driving rack 67 to slide, thereby driving the transmission gear ring 64 to rotate. This rotation direction is the locking direction of the one-way bearing 63. Therefore, the first transmission roller 61 can be driven to rotate by a certain angle. When the first transmission roller 61 rotates, it can drive the second transmission roller 62 to rotate through the speed regulating mechanism, so that the second transmission roller 62 rotates by a certain angle. When the second transmission roller 62 rotates, it can drive the turntable 68 to rotate. During the process of the two forming modules 33 approaching and clamping each other, when the driving rack 67 drives the transmission gear ring 64 to rotate, this rotation direction is the free state of the one-way bearing 63. Therefore, it cannot drive the first transmission roller 61 to rotate. The staff can set the spraying of the release agent through the speed regulating mechanism. As the forming module 33 continuously opens and closes, when the set number of times of release agent spraying is reached by the staff, at this time, the adjusting screw 611 and the transmission ball head 612 on the turntable 68 can rotate past the V-shaped transmission plate 610 at the end of the support rod 69 on the pressure plate 53 and drive the V-shaped transmission plate 610 to slide, thereby driving the pressure plate 53 to press and reset through the spring telescopic rod 52, so that the liquid guide bladder 51 on the pressure plate 53 is compressed and stretched. When the liquid guide bladder 51 is compressed, since one-way valves with opposite flow directions are installed in the conduit 54 and the liquid inlet pipe 55, the release agent in the liquid guide bladder 51 can enter the nozzle 46 along the conduit 54 and be sprayed onto the forming head 35. During the stretching process of the liquid guide bladder 51, the release agent can be pumped into the liquid guide bladder 51 through the liquid inlet pipe 55; When it is necessary to adjust the spraying metering of the mold release agent, the adjusting screw 611 can be rotated to adjust the position of the transmission ball head 612. When it passes through the V-shaped transmission plate 610, it will push the V-shaped transmission plate 610 to different positions, so as to control the compression degree of the liquid guide bladder 51, thereby realizing the adjustment of the spraying metering of the mold release agent. And the staff can adjust the spraying of the mold release agent once corresponding to the molding times of the injection molded product. During the adjustment, the connecting screw 71 can be rotated. The connecting screw 71 is screwed with the adjusting disc 73, and the adjusting disc 73 is slidably connected with the guide rod 72. Therefore, when the connecting screw 71 rotates, it can drive the adjusting disc 73 to slide along the guide rod 72, so that the transmission wheel 74 adjusts its position between the first transmission roller 61 and the second transmission roller 62. The first transmission roller 61 and the second transmission roller 62 are arranged in a frustum shape and are oppositely arranged. Therefore, by adjusting the position of the transmission wheel 74, the transmission ratio between the first transmission roller 61 and the second transmission roller 62 can be changed, so as to change the single rotation angle of the turntable 68, and thus spray the mold release agent once corresponding to different demolding times, ensuring that the mold release agent can be automatically sprayed without manual operation.
