Description

Technical Field

[0001] This utility model relates to the field of silicone injection molding, and in particular to a rapid prototyping injection molding device for silicone signs. Background Technology

[0002] Injection molding machines are primary molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Silicone injection molding machines are specifically designed for processing silicone materials. They can be used to produce silicone signs. However, after the silicone is injected into the mold, it needs to be cooled and set. The exit temperature of silicone in the injection molding machine is typically between 165-185 degrees Celsius. Therefore, to improve molding efficiency, cooling devices are usually installed inside the mold to cool the silicone signs. However, to maximize production efficiency, the silicone signs are generally not removed from the mold until they are completely cooled. This results in the silicone signs still being hot when removed, causing burns to workers' hands when they manually handle them. Therefore, a rapid molding injection molding device for silicone signs is needed to solve the problem of burns caused by the high temperature of the molded silicone signs.

[0003] To this end, Chinese Patent Publication No. CN219028389U discloses an injection molding equipment for the rapid prototyping of silicone signs, including a silicone sign injection molding platform. A groove is formed on the upper surface of the injection molding platform, and a first lower mold and a second lower mold are symmetrically arranged laterally inside the groove. A water storage structure, including a water tank, is provided at the bottom of the first and second lower molds. The bottom of the water tank is fixedly connected to the silicone sign injection molding platform. This invention, through the design of the water storage structure and the cooling chambers formed inside the first and second lower molds, allows the injection of low-temperature liquid from the outside into the first and second lower molds, achieving rapid cooling after injection molding. This cools the silicone sign and accelerates its cooling efficiency. Furthermore, the cooling structure allows for the circulation and cooling of the liquid inside the water tank, reducing water waste. Therefore, this device is suitable for widespread application.

[0004] The aforementioned patent requires workers to remove the molded silicone signs from between the molds after injection molding and cooling. During removal, excessive force may cause breakage, affecting the molding rate of the silicone signs. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0024] according to Figures 1 to 7 As shown, a rapid prototyping injection molding device for silicone signs includes an injection worktable 1 connected to an injection molding machine. A fixed mold 3 is slidably connected to the top of the injection worktable 1, and an injection port 34 is fixedly connected to the rear end of the fixed mold 3. The fixed mold 3 is connected to the extrusion end of the injection molding machine through the injection port 34. A gantry frame 2 is fixedly connected to the top of the injection worktable 1, and a liftable lifting frame 5 is fixedly connected to the bottom of the gantry frame 2. A movable mold 6 is connected to the front end of the lifting frame 5, and a vertical sliding mechanism for pushing the silicone sign from inside the movable mold 6 outwards is slidably connected to the top of the lifting frame 5. The ejection mechanism 7 is provided. Multiple air-cooling mechanisms 8 are fixedly connected to the top of the injection worktable 1 and are arranged around the fixed mold 3. The air-cooling mechanisms 8 rotate upward synchronously when the lifting frame 5 rises. At the rear end of the lifting frame 5 and the bottom of the injection worktable 1, water-cooling mechanisms 9 with the same structure are fixedly connected to cool the corresponding fixed mold 3 and moving mold 6. The fixed mold 3 and the moving mold 6 are respectively provided with a first cooling groove 10 in the shape of a disc. The two water-cooling mechanisms 9 are respectively connected to the corresponding mold and the moving mold 6 through the first cooling groove 10.

[0025] In practical implementation, two parallel electric push rods 4 are fixedly connected to the bottom of the portal frame. The extended ends of the two electric push rods 4 are fixedly connected to the top of the lifting frame 5. The lifting frame 5 is moved up and down by controlling the extension distance of the two electric push rods 4. The lifting frame 5 has second sliding grooves 62 on both sides. The moving mold 6 has second sliders 61 on both sides. The moving mold 6 is slidably connected to the lifting frame 5 through the second sliding grooves 62 and the second sliders 61. At the same time, the second sliders 61 and the lifting frame 5 have second threaded holes on both sides. When the second sliders 61 slide into the bottom of the second sliding grooves 62, the second threaded holes on both sides of the lifting frame 5 and the second sliders 61 are connected. The positions of the second threaded holes on the surface correspond to each other. At this time, the moving mold 6 is fixedly installed at the front end of the lifting frame 5 by sequentially connecting the second threaded holes on both sides of the lifting frame 5 and the second threaded holes on the surface of the second slider 61 through the threads. When the lifting frame 5 moves to the bottom, the lower surface of the moving mold 6 contacts the upper surface of the fixed mold 3, so that the moving mold 6 and the fixed mold 3 are combined to form a complete mold. The rear end of the fixed mold 3 is provided with an injection port 34, and the extrusion end of the injection molding machine is connected to the injection port 34. After the moving mold 6 and the fixed mold 3 are combined to form a complete mold, the injection molding machine heats the silicone raw material and extrudes it into the cavity between the moving mold 6 and the fixed mold 3 to realize the injection molding of the silicone sign.

[0026] After the silicone raw material is injected into the moving mold 6 and the fixed mold 3, two water-cooling mechanisms 9 use circulating coolant to cool the moving mold 6 and the fixed mold 3 respectively. The decrease in temperature of the moving mold 6 and the fixed mold 3 achieves cooling and shaping of the silicone sign after injection. After a certain period of time, the electric push rod 4 controls the lifting frame 5 to move upward. At this time, the moving mold 6 and the fixed mold 3 separate. Because of the structure of the moving mold 6 during mold production, the silicone sign will be temporarily retained in the moving mold 6. Therefore, when the lifting frame 5 moves upward, the ejection mechanism 7 can demold the molded silicone sign retained in the moving mold 6. At the same time, four air-cooling devices can be set up, and the four air-cooling devices are arranged around the fixed mold 3. The four air-cooling devices can move synchronously when the lifting frame 5 moves upward. The rotating mechanism flips backward to ensure that the air-cooling mechanism 8 flips upward as the moving mold 6 moves upward, adjusting the viewing angle. This facilitates the air-cooling mechanism 8 to follow the movement of the moving mold 6 and perform air-cooling treatment on the moving mold 6 and the silicone nameplate inside the moving mold 6. Two water-cooling devices are provided, each connected to the first cooling tank 10 inside the moving mold 6 and the fixed mold 3, respectively. Coolant circulates in the water-cooling devices and the corresponding first cooling tank 10 inside the mold. During cooling, the moving mold 6 and the fixed mold 3 transfer the heat of the silicone material to the coolant. The cooling treatment of the moving mold 6 and the fixed mold 3 is achieved through the circulation of the coolant. Subsequently, the cooling mechanism further cools the coolant, enabling the coolant to circulate and cool the moving mold 6 and the fixed mold 3 repeatedly.

[0027] Furthermore, two parallel first slide grooves 32 are provided on the front surface of the injection molding worktable 1, and a baffle 33 for fixing the fixed mold 3 is fixedly connected to the top surface of the injection molding worktable 1. Two parallel first sliders 31 are fixedly connected to the bottom of the fixed mold 3. The two first sliders 31 are slidably connected to the corresponding first slide grooves 32 respectively. First threaded holes are provided on both sides of the fixed mold 3 and the flow side of the baffle 33 respectively. When the first slider 31 slides into the rear end of the first slide groove 32, the fixed mold 3 is fixedly connected to the baffle 33 by bolts.

[0028] In specific implementation, the first slider 31 at the bottom of the moving mold 6 uses the first slide groove 32 on the front surface of the injection worktable 1 to facilitate the sliding connection between the moving mold 6 and the injection worktable 1. When the moving mold 6 slides to the rear end of the first slide groove 32, the baffle 33 can block the fixed mold 3. At the same time, the fixed mold 3 and the baffle 33 are respectively provided with first threaded holes on both sides of the fixed mold 3 and on the surface of the baffle 33. The fixed mold 3 is fixedly installed between the baffles 33 by threaded bolts in the first threaded holes, thereby fixing the fixed mold 3. At the same time, it is convenient to replace the fixed mold 3 after loosening the bolts.

[0029] Furthermore, the water-cooling mechanism 9 includes a cooling plate 91. The upper cooling plate 91 is fixedly connected to the top surface of the lifting frame 5, and the lower cooling plate 91 is fixedly connected to the bottom surface of the injection molding workbench 1. The cooling plate 91 has a disc-shaped second cooling tank 95. The inlet and outlet of the second cooling tank 95 are respectively connected to a coolant inlet pipe 92 and a coolant outlet pipe 93. A water pump 94 is fixedly connected to the coolant inlet pipe 92. The upper cooling plate 91 is connected and communicates with the inlet and outlet of the first cooling tank 10 in the moving mold 6 through the coolant inlet pipe 92 and the coolant outlet pipe 93, respectively. The lower cooling plate 91 is connected and communicates with the inlet and outlet of the first cooling tank 10 in the fixed mold 3 through the coolant inlet pipe 92 and the coolant outlet pipe 93, respectively. Heat dissipation fins 96 are fixedly connected to the rear end of the cooling plate 91, and multiple second cooling fans 97 are fixedly connected to the rear end of the heat dissipation fins 96.

[0030] In practical implementation, each of the two cooling plates 91 has a second cooling tank 95. The inlet and outlet pipes of the second cooling tanks 95 in the two cooling plates 91 are respectively connected to a coolant inlet pipe 92 and a coolant outlet pipe 93. The two coolant inlet pipes 92 and coolant outlet pipes 93 connected to the cooling plates 91 are respectively connected to the inlet and outlet of the first cooling tank 10 in the moving mold 6 and the fixed mold 3. At the same time, water pumps 94 are installed on the two coolant inlet pipes 92, and the water pumps 94 allow the coolant to flow between the first cooling tank 10 and the second cooling tank 95. The coolant circulates within the coolant inlet pipe 92 and coolant outlet pipe 93. After absorbing heat in the first cooling tank 10, the coolant flows into the second cooling tank 95. The heat from the coolant is transferred to the heat dissipation fins 96 by the cooling plate 91 for cooling. At the same time, several second cooling fans 97 can further dissipate heat from the heat dissipation fins 96, effectively improving the cooling efficiency of the coolant. This also improves the heat exchange efficiency of the coolant on the moving mold 6 and the fixed mold 3, further improving the efficiency of the silicone nameplate cooling and molding within the moving mold 6 and the fixed mold 3.

[0031] Furthermore, the ejection mechanism 7 includes a horizontal plate 71, with a top shaft 72 fixedly connected to the top of the horizontal plate 71 and a plurality of ejection rods 73 fixedly connected to the bottom of the horizontal plate 71. The bottom ends of the ejection rods 73 extend through the lifting frame 5 to the top of the moving mold 6. Springs 74 are respectively sleeved on the surface of the ejection rods 73. One end of the spring 74 is fixedly connected to the bottom of the horizontal plate 71, and the other end of the spring 74 is fixedly connected to the top of the lifting frame 5.

[0032] In practical implementation, the top of the lifting frame 5 and the top of the moving mold 6 are respectively provided with ejection holes for the ejector rod 73 to slide. After the silicone label has cooled for a certain period of time, the telescopic end of the electric push rod 4 drives the lifting frame 5 to move upward. The upward movement of the lifting frame 5 drives the crossbar to move upward synchronously. When the crossbar 71 moves upward, the top of its top shaft 72 contacts the bottom of the portal frame 2. Then, as the lifting frame 5 continues to rise, the top shaft 72 is blocked by the portal frame 2, causing the crossbar 71 to move downward. The downward movement of the crossbar 71 drives multiple... Ejector rod 73 ejects downward from the top of moving mold 6, achieving downward ejection and demolding of the silicone sign. Conversely, when moving mold 6 moves downward, ejector shaft 72 is no longer blocked by gantry frame 2. At this time, the elastic force of spring 74 pushes ejector rod 73 upward. When ejector rod 73 is pushed upward, spring 74 keeps ejector rod 73 in the ejection hole, preventing ejector rod 73 from protruding and affecting the injection molding of silicone sign. Ejector rod 73 can effectively improve the demolding efficiency of silicone sign and avoid damage to silicone sign during manual demolding.

[0033] Furthermore, the air-cooled cooling mechanism 8 includes a first cooling fan 81, with rotating shafts fixedly connected to both sides of the first cooling fan 81. The rotating shafts are radially rotatably connected to mounting rods 82. The bottom of the mounting rods 82 is fixedly connected to the upper surface of the injection molding worktable 1. The rotating shaft on the left passes through the mounting rod on the left and is coaxially fixedly connected to a spur gear 83. A rack 84 is fixedly connected to one side of the lifting frame 5. The rack 84 meshes with the spur gear 83. A limit block 85 is obliquely fixedly connected to one side of the lifting rod to limit the backward flipping of the first cooling fan 81.

[0034] In practical implementation, the first cooling fan 81 is rotatably connected to the upper surface of the injection molding workbench 1 via two mounting rods 82. The blowing ends of the first cooling fan 81 are respectively set towards the fixed mold 3. When the lifting frame 5 moves upward, it drives the rack 84 to move upward. The upward movement of the rack 84 drives the spur gear 83 to rotate clockwise. The clockwise rotation of the spur gear 83 drives the first cooling fan 81 to rotate clockwise around the shaft. Because the length of the rack 84 is fixed, when the lifting frame 5 continuously drives the rack 84 to move upward, the rack 84 will disengage from the spur gear 83. When the hot air fan 81 rotates clockwise, its center of gravity shifts backward. Therefore, the first cooling fan 81 can still rotate backward after the spur gear 83 and rack 84 disengage. During the rotation of the first cooling fan 81, its air outlet rotates backward as the moving mold 6 moves upward. At this time, the limit block 85 can limit the extreme position of the first cooling fan 81's backward rotation. Therefore, the air outlet of the first cooling fan 81 can continuously blow air onto the silicone label surface at the bottom of the moving mold 6, realizing dynamic airflow adjustment, further increasing the cooling speed of the silicone label, and improving the efficiency of rapid molding of the silicone label.

[0035] Furthermore, two parallel stabilizing shafts 13 are fixedly connected to the bottom of the gate frame. The bottom ends of the stabilizing shafts 13 are fixedly connected to the upper surface of the injection molding worktable 1. Stabilizing blocks 14 are fixedly connected to both sides of the lifting frame 5. The stabilizing blocks are slidably connected to the corresponding stabilizing shafts 13.

[0036] In practice, the top and bottom ends of the two stabilizing shafts 13 are fixedly connected to the bottom of the portal frame and the upper surface of the injection molding worktable 1, respectively. The sliding connection between the stabilizing blocks on both sides of the lifting frame 5 and the stabilizing shafts 13 can effectively improve the stability of the lifting frame 5 when it is controlled by the electric push rod 4 to move up and down at the bottom of the portal frame.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
