Description

Technical Field

[0001] This utility model relates to the field of automotive interior mold technology, and more specifically, to an automotive interior mold for internal cooling. Background Technology

[0002] Injection molds are tools for producing plastic products, and also tools for giving plastic products a complete structure and precise dimensions. In the production process of automotive interior parts, the cooling effect of the mold has a crucial impact on product quality and production efficiency. During injection molding, the molded parts need to be cooled in order to quickly solidify and remove them.

[0003] Traditional automotive interior mold cooling often employs a holistic cooling method, which involves setting up uniform cooling channels around or inside the mold to circulate coolant throughout the entire mold. This method cannot provide targeted cooling based on factors such as the thickness, shape, and material distribution of different areas of the interior parts. This results in inconsistent shrinkage of different parts of the product, easily leading to problems such as warping, deformation, and poor surface quality. For example, at corners and junctions between thin and thick walls of interior parts, uneven coolant flow or heat accumulation can easily cause localized overheating, potentially leading to defects such as shrinkage cavities and cracks in these areas. Therefore, a method for internally cooling automotive interior molds is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an internal cooling automotive interior mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an internal cooling automotive interior mold, comprising a bottom mold and a top mold adapted to the bottom mold. The top of the bottom mold is fixedly connected to a positioning frame and has multiple positioning slots. The bottom of the top mold is fixedly connected to multiple positioning rods and has positioning grooves. Positioning is facilitated by the positioning rods and positioning slots. The positioning frame and positioning grooves facilitate sealing around the mold cavity. A first main water pipe is symmetrically arranged on both sides of the top mold. Multiple cooling channels are arranged in the middle of the top mold. Coolant is conveniently input and output through the first main water pipes, and the cooling channels uniformly cool the bottom wall of the top mold.

[0006] The inner cavity of the bottom mold is provided with multiple first cooling chambers and second cooling chambers. The first cooling chambers are located directly below the thin-walled area of ​​the finished interior trim, and the second cooling chambers are located directly below the thick-walled area of ​​the finished interior trim. Multiple heat-conducting plates are fixedly connected to the middle of the second cooling chamber. Coolant enters the interior of the first and second cooling chambers to cool the bottom mold. The first and second cooling chambers can achieve regional cooling, so that the cooling effect of the thin-walled area and the thick-walled area is different. This allows the thin-walled area and the thick-walled area of ​​the interior trim to be cooled at the same time, making the cooling effect more uniform, thereby avoiding product deformation and improving the cooling effect. The heat-conducting plates also increase the cooling intensity of the thick-walled area of ​​the interior trim, improving the performance.

[0007] Multiple second main water pipes are symmetrically arranged on both sides of the bottom mold. Both ends of the first and second cooling chambers are connected to connecting pipes. Both ends of the connecting pipes and the cooling channels are equipped with anti-backflow mechanisms. The second main water pipes facilitate water inlet and outlet, and the connecting pipes facilitate the injection and discharge of coolant into the first and second cooling chambers. The anti-backflow mechanism can prevent coolant backflow, improve the coolant flow effect, and thus improve the cooling effect.

[0008] Preferably, mounting plates are symmetrically fixedly connected around the bottom mold, the positioning groove is adapted to the positioning frame, and the positioning groove corresponds to the positioning frame. The mounting plates facilitate installation and fixation, and the positioning frame and positioning groove facilitate limiting the position around the injection molding.

[0009] Preferably, the positioning rod and the positioning slot correspond to each other, with one end of the positioning rod extending into the interior of the positioning slot. Cooling pipes are connected to one side of both the first main water pipe and the second main water pipe. The positioning effect of the bottom mold and the top mold is improved through the cooperation of the positioning rod and the positioning slot.

[0010] Preferably, the cooling channel is adapted to the shape of the bottom wall of the top mold, and the number of cooling channels is evenly distributed in the middle of the top mold. The two ends of the cooling channel are respectively connected to the first main water pipe on both sides of the top mold. The cooling channel makes the cooling intensity the same at any position at the bottom of the top mold, and the first main water pipe facilitates the input or output of coolant to multiple cooling channels.

[0011] Preferably, both ends of the first cooling chamber and the second cooling chamber are connected to the second main water pipes on both sides of the bottom mold through connecting pipes, so that coolant can be injected into or output into the first cooling chamber and the second cooling chamber through the second main water pipes.

[0012] Preferably, the air counterflow mechanism includes a movable plate disposed in the middle of the connecting pipe, a sealing plate fixedly connected to the side of the movable plate near the water inlet, and limit blocks symmetrically fixedly connected around the perimeter of the movable plate.

[0013] Preferably, a stabilizing rod is inserted in the middle of the limiting block, and a spring is sleeved on the end of the stabilizing rod away from the sealing plate. By pushing the limiting block with the spring, the movable plate can drive the sealing plate to seal the connecting pipe. When the inlet water pushes the sealing plate, or the outlet water pushes the sealing plate, the flow effect can be achieved, and the coolant backflow can be avoided, thus improving the cooling effect.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model firstly achieves zoned cooling when cooling the interior trim inside the bottom mold by setting a first cooling chamber and a second cooling chamber. This allows for different cooling effects in thin-walled and thick-walled areas of the interior trim, resulting in a more uniform cooling effect, thereby preventing product deformation and improving the cooling effect. Furthermore, the anti-backflow mechanism prevents coolant backflow, improves coolant flow, and further enhances the coolant delivery and cooling effect, thus improving the quality of the finished product.

[0016] 2. This utility model also allows for the simultaneous injection of coolant into multiple first and second cooling chambers and cooling channels during the injection and output of coolant via a second main water pipe and a first main water pipe. It also allows for the collection and recycling of coolant during discharge, facilitating input and output. The combination of the positioning frame and positioning groove facilitates the limiting of the four sides of the injection-molded interior parts. The combination of the positioning rod and positioning slot improves the positioning effect of the bottom mold and top mold.

[0017] In summary, through the interaction of the above-mentioned multiple functions, regional cooling can be achieved, which can make the cooling effect different for thin-walled and thick-walled areas of the interior, making the cooling effect more uniform, thereby avoiding product deformation and improving the cooling effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1-4 The internal cooling automotive interior mold shown includes a bottom mold 1 and a top mold 2 that is fitted to the bottom mold 1. The top of the bottom mold 1 is fixedly connected to a positioning frame 3 and has multiple positioning slots 6. The bottom of the top mold 2 is fixedly connected to multiple positioning rods 5 and has positioning grooves 4. The positioning rods 5 and positioning slots 6 facilitate positioning. The positioning frame 3 and positioning grooves 4 cooperate to seal the mold cavity. The top mold 2 has a first main water pipe 7 symmetrically arranged on both sides. The top mold 2 has multiple cooling channels 8 in the middle. The first main water pipe 7 facilitates the input and output of coolant, and the cooling channels 8 uniformly cool the bottom wall of the top mold 2.

[0025] The inner cavity of the bottom mold 1 is provided with multiple first cooling chambers 9 and second cooling chambers 10. The first cooling chambers 9 are located directly below the thin-walled area of ​​the finished interior trim, and the second cooling chambers 10 are located directly below the thick-walled area of ​​the finished interior trim. Multiple heat-conducting plates 11 are fixedly connected to the middle of the second cooling chambers 10. Multiple second main water pipes 12 are symmetrically arranged on both sides of the bottom mold 1. Both ends of the first cooling chambers 9 and the second cooling chambers 10 are connected to connecting pipes 13. Both ends of the connecting pipes 13 and the cooling channel 8 are provided with anti-backflow mechanisms. The bottom mold 1 can be cooled by the coolant entering the interior of the first cooling chambers 9 and the second cooling chambers 10, and the cooling effect is achieved through the first cooling chambers 9 and the second cooling chambers 10. The first cooling chamber 9 and the second cooling chamber 10 can achieve zoned cooling, resulting in different cooling effects for thin-walled and thick-walled areas. This allows both thin-walled and thick-walled areas of the interior parts to be cooled simultaneously, making the cooling effect more uniform, thus preventing product deformation and improving the cooling effect. The heat-conducting plate 11 enhances the cooling intensity of the thick-walled areas of the interior parts, improving the performance. The second main water pipe 12 facilitates water inlet and outlet, and the connecting pipe 13 facilitates the injection and discharge of coolant into the first cooling chamber 9 and the second cooling chamber 10. The anti-backflow mechanism prevents coolant backflow, improving the coolant flow effect and thus enhancing the cooling effect.

[0026] As attached Figure 1-3 As shown, mounting plates 14 are symmetrically fixedly connected around the bottom mold 1. Positioning grooves 4 and 3 are adapted to each other, and positioning rods 5 and 6 correspond to each other. One end of the positioning rod 5 extends into the interior of the positioning slot 6. Cooling pipes are connected to one side of both the first main water pipe 7 and the second main water pipe 12. The shape of the cooling channels 8 is adapted to the bottom wall of the top mold 2. Several cooling channels 8 are evenly distributed in the middle of the top mold 2. Both ends of the cooling channels 8 are connected to the first main water pipes 7 on both sides of the top mold 2. Both ends of the first cooling chamber 9 and the second cooling chamber 10 are connected to the bottom mold 1 via connecting pipes 13. The two sides of the second main water pipe 12 are connected and can be easily installed and fixed by the mounting plate 14. The positioning frame 3 and positioning groove 4 can be used to limit the surrounding area of ​​the injection molding. The positioning rod 5 and positioning slot 6 work together to improve the positioning effect of the bottom mold 1 and the top mold 2. Cooling pipes can be used to inject coolant or discharge coolant from the cooling pipes of the first main water pipe 7 and the second main water pipe 12 on the other side, so as to realize the flow of cooling pipes and improve the cooling effect. The cooling channel 8 can make the cooling intensity the same at any position of the bottom of the top mold 2. The second main water pipe 12 can be used to inject or output coolant into the first cooling chamber 9 and the second cooling chamber 10.

[0027] As attached Figure 2-4As shown, the air counterflow mechanism includes a movable plate 15 located in the middle of the connecting pipe 13. A sealing plate 16 is fixedly connected to the side of the movable plate 15 near the water inlet. Limiting blocks 17 are symmetrically fixed around the movable plate 15. A stabilizing rod 18 is inserted into the middle of the limiting block 17. A spring 19 is sleeved on the end of the stabilizing rod 18 away from the sealing plate 16. By pushing the limiting block 17 with the spring 19, the movable plate 15 can drive the sealing plate 16 to seal the connecting pipe 13. When the water inlet pushes the sealing plate 16, or the water outlet pushes the sealing plate 16, the flow effect can be achieved, and the backflow of coolant can be avoided, thus improving the cooling effect.

[0028] It is worth noting that the top of the top mold 2 is provided with an injection port, one end of which is connected to the mold cavity of the bottom mold 1 and is offset from the cooling channel 8 for easy use.

[0029] When this utility model is in use, coolant is injected into the interior of the second main water pipe 12 and the first main water pipe 7 through the cooling pipe on one side of the second main water pipe 12, and then enters the interior of the second cooling chamber 10, the first cooling chamber 9, and the cooling channel 8. It is then sequentially entered into the middle of the first main water pipe 7 and the second main water pipe 12 on the other side for discharge. This allows the coolant to pass through the middle of the top mold 2 and the bottom mold 1, and through the first cooling chamber 9 and the second cooling chamber 10, so that the thin-walled area and the thick-walled area of ​​the interior parts inside the bottom mold 1 can be cooled simultaneously, making the cooling effect more uniform and thus avoiding product deformation.

[0030] Furthermore, the anti-backflow mechanism ensures proper coolant flow, preventing backflow and ensuring optimal cooling performance. The positioning rod 5 and positioning slot 6 facilitate convenient positioning and assembly.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
