Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a molding mold for a car interior door panel speaker cover. Background Technology

[0002] The development of the automotive industry has driven the improvement of the quality requirements for automotive interiors. As an important component of the interior, the quality and appearance of the door panel speaker cover directly affect the overall quality of the vehicle. It needs to have both good sound transmission and aesthetics. However, the molding of such parts requires high molds. Dense mesh can easily lead to insufficient mold core strength and insufficient injection material. As an exposed part, the surface must be free of marks, which traditional molds cannot meet. Traditional molds have high maintenance costs and are prone to product deformation during demolding. Therefore, in order to solve these problems, related molding dies have emerged.

[0003] The product shape space is formed by the closure of the cavity and the core. After injection molding, cooling and demolding, the finished product is made. When the mold is closed, the moving mold and the fixed mold are closed, and the cavity and the core form a closed cavity corresponding to the cover. The guide structure ensures accuracy. During injection molding, the molten plastic is injected into the cavity through the runner and gate. The fine core forms a mesh, and the venting structure removes air. During pressure holding and cooling, the pressure is maintained to prevent backflow, and the cooling water solidifies the plastic.

[0004] While automotive interior door panel speaker cover molding dies have driven the development of the industry and product molding, they have a major limitation: the inability to flexibly change the molds used to produce finished products. This means that a single mold can typically only correspond to one specification of speaker cover. However, automotive interior styles are diverse, and speaker covers need to be adapted to different car models and design styles, with specifications frequently changing. The inability to flexibly change molds necessitates the creation of separate molds for each specification, which not only increases costs but also leads to more idle molds, significantly reducing the overall utilization rate of the equipment and making it difficult to adapt to rapidly changing market demands. Therefore, a new automotive interior door panel speaker cover molding die is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mixing device for processing plastic buckets, which solves the problem of the inconvenience of disassembling and cleaning the mixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A connecting plate is fixedly connected to the inner wall of the support plate. Two clamping blocks are slidably connected to the bottom of the connecting plate. A cylinder is fixedly connected to the inner wall of the support plate.

[0009] The ejection mechanism includes a second cylinder, the outer wall of which is fixedly connected to the inner wall of the base. A push block is fixedly connected to the drive end of the second cylinder. A secondary component is slidably connected to the top of the push block. A feeding plate is fixedly connected to the inner wall of the pressure table. An inclined column is fixedly connected to the inner wall of the pressure table. A feeding plate is slidably connected to the inner wall of the pressure table. An ejection block is slidably connected to the inner wall of the feeding plate. A fixed column is fixedly connected to the top of the push block.

[0010] The limiting component includes two support blocks, with one side of each support block fixedly connected to the outer wall of one of the connecting columns. The inner wall of the support plate has two sliding grooves, and the inner wall of the connecting plate has two through holes.

[0011] The outer wall of the support block is slidably connected to the inner wall of the slide groove, the outer wall of the connecting column is slidably connected to the inner wall of the through hole, and the driving end of the cylinder is fixedly connected to the inner wall of one of the support blocks.

[0012] The secondary component includes a second pusher block, the bottom of which is slidably connected to the top of the first pusher block. A sliding column is slidably connected to the inner wall of the pressure table, a protruding plate is fixedly connected to the outer wall of the sliding column, and a spring is sleeved on the outer wall of the sliding column.

[0013] The inner wall of push block two is slidably connected to the outer wall of the inclined column, and the inner wall of push block one is slidably connected to the outer wall of the fixed column.

[0014] The top of the spring is fixedly connected to the inner wall of the pressure table, and the bottom of the spring is fixedly connected to the top of the convex plate.

[0015] The top of the sliding column is fixedly connected to the bottom of the ejector block, and the top of the fixed column is fixedly connected to the bottom of the feeding plate.

[0016] The outer wall of the drive end of the second cylinder is slidably connected to the inner wall of the pressure table, and the top of the second push block is in contact with the bottom of the sliding column.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by activating cylinder one located on the inner wall of the support plate, the driving force output by cylinder one will act on the support block. Thanks to the guide and limit of the support block by the slide groove, the support block can move along a stable path, thereby driving the connecting column, clamping block and pull plate connected to it to move synchronously. At the same time, under the action of the activity space provided by the through hole, the positioning of the rotating column and the force transmission of the push plate, another pull plate will drive the corresponding connecting column and clamping block to move, so that the two clamping blocks can open and close at the bottom of the connecting plate. This design allows the device to be adapted to molds of different specifications, significantly improving the utilization rate.

[0020] 2. In this utility model, the second cylinder located on the inner wall of the base is activated. The driving force output by the second cylinder will drive the first push block to move. Thanks to the guiding and limiting of the fixed column and the inclined column, the first push block can push the second push block along the predetermined path. The first push block first drives the fixed column to push the feeding plate to complete the initial ejection. Then the second push block moves with the first push block and contacts the sliding column, pushing the sliding column and the ejection block to achieve the secondary ejection of the forming mold. This design greatly improves the ease of use of the device. At the same time, the convex plate squeezes the spring to generate elastic potential energy to buffer the thrust, which can significantly extend the service life of the device.

[0033] Working principle: The cylinder 68 located on the inner wall of the support plate 4 is activated. Thanks to the presence of the slide groove 652, the driving force of the cylinder 68 pushes the support block 651 to move. This causes a connecting column 64 to drive a clamping block 66 and a pull plate 63 to move. Thanks to the presence of the through hole 653, the limiting effect of the rotating column 61, and the transmission effect of the push plate 62, another pull plate 63 drives another connecting column 64 to drive another clamping block 66 to move. This causes the two clamping blocks 66 to open and close at the bottom of the connecting plate 67. This allows the entire device to be adapted to various molds of different specifications for operation, thereby greatly improving the utilization rate of the entire device.

[0034] Activating cylinder 71 located on the inner wall of base 1 causes the driving force of cylinder 71 to drive push block 72 to move. Thanks to the presence of fixed column 77 and inclined column 73, push block 72 can push push block 741 along a predetermined path. Push block 72 first drives fixed column 77 to push the feeding plate 75 to be ejected. Then, push block 741 moves with push block 72 and contacts sliding column 742 to continue moving. This causes sliding column 742 to push ejector block 76 to eject the mold again, greatly improving the ease of use of the entire device. At the same time, the convex plate 743 compresses spring 744, causing spring 744 to undergo elastic deformation and generate elastic potential energy to buffer the pushing force of push block 741, greatly extending the service life of the entire device. Thanks to the presence of hydraulic cylinder 3 on the inner wall of base 2, support plate 4 can slide stably on the inner wall of base 2, greatly improving the stability of the entire device during operation.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
