Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically to a molding die for automotive interior panels with a guiding mechanism. Background Technology

[0002] Automotive interior panel molding dies are tools used to produce automotive interior panels. These dies are typically made of metal and have specific shapes and structures for molding plastic or metal materials on equipment such as stamping presses or injection molding machines.

[0003] Utility model patent CN218286569U discloses an injection mold for automotive door interior panels, including an operating table, a guide bucket, and a water pump. A lower mold is located above the operating table, and an upper mold is located above the lower mold. The lower mold has a cavity inside, and a flow cavity is located below the cavity and inside the lower mold. A liquid storage cavity is located below the flow cavity, and heat dissipation holes are equidistantly opened on both sides of the liquid storage cavity. This utility model, by adding overflow holes, a guide bucket, an impeller, and stirring blades, enables the coolant overflowing from the flow cavity to converge in the guide bucket and flow down to push the impeller, causing it to rotate. This rotation of the shaft drives the stirring blades to stir and dissipate heat from the coolant in the liquid storage cavity, increasing the contact area between the coolant and air. After the coolant cools down, the temperature reduction of the outside of the mold cavity is improved, thus effectively improving the cooling effect of the injection mold and greatly increasing its cooling efficiency.

[0004] In the aforementioned existing technology, during mold use, it is inconvenient to guide the movement of the upper mold during the mold closing process, which affects the accuracy of the upper mold movement and consequently the mold closing accuracy, ultimately impacting the product molding effect. Furthermore, the molded workpiece tends to adhere to the inner wall of the mold, making demolding and removal difficult. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a molding die for automotive interior panel parts with a guiding mechanism, which solves the problem of inconvenient guiding of the movement of the upper mold, and also solves the problem that the workpiece is easy to stick to the inner wall of the mold after molding and is inconvenient to demold.

By designing the guiding mechanism, the movement of the upper mold can be guided.

[0009] Preferably, the worktable has a groove inside, and a ball bearing is slidably connected inside the groove. By designing the groove, the ball bearing can roll along the groove.

[0010] Preferably, the vibration mechanism includes a motor, which is fixedly installed inside the worktable. The output end of the motor is rotatably connected to the worktable. A rotating shaft is fixedly connected to the outer side of the motor output end, and the rotating shaft is rotatably connected to the worktable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the design of a hydraulic cylinder. The output end of the hydraulic cylinder can drive the upper mold to move downward. The injection molding of the interior panel can be performed by closing the upper and lower molds. During the movement of the upper mold, the sliding connection between the guide rod and the worktable with the ball bearings can guide the movement of the connecting plate and the upper mold, thereby improving the mold closing accuracy of the upper mold and thus improving the workpiece forming effect. Furthermore, during the movement of the guide rod and the ball bearings, the compression of the sponge sleeve can squeeze out the lubricating oil inside the sponge sleeve, thereby lubricating the guide components, reducing guide friction and extending service life.

[0015] 2. This utility model, through the design of the motor, allows the output end of the motor to drive the rotating shaft to rotate, which in turn drives the ejector rod and impact block to rotate. The rotating impact block contacts the lower mold and impacts it, thus vibrating the lower mold. This avoids the problem of material sticking to the mold and being difficult to remove during demolding in the molding process. Attached Figure Description

An upper mold 10 is fixedly installed on the bottom of the connecting plate 7. A guiding mechanism 8 is provided on the connecting plate 7. A vibration mechanism 9 is provided on the lower mold 4.

[0024] Please see Figure 1 , Figure 2 , Figure 3 The guiding mechanism 8 includes a guide rod 81. The top of the connecting plate 7 is fixedly connected to the guide rod 81. The guide rod 81 is slidably connected to the worktable 3. A ball bearing 82 is movably sleeved inside the guide rod 81. The ball bearing 82 is movably connected to the worktable 3. A groove 83 is opened inside the worktable 3. The ball bearing 82 is slidably connected inside the groove 83. By designing the groove 83, the ball bearing 82 can roll along the groove 83. A sponge sleeve 84 is fixedly connected inside the worktable 3. A flow channel 85 is opened inside the worktable 3. The flow channel 85 communicates with the sponge sleeve 84. A plug 86 is snapped inside the flow channel 85. By designing the guiding mechanism 8, the movement of the upper mold 10 can be guided.

[0025] Please see Figure 1 , Figure 4 , Figure 5The vibration mechanism 9 includes a motor 91, which is fixedly installed inside the worktable 3. The output end of the motor 91 is rotatably connected to the worktable 3. A rotating shaft 92 is fixedly connected to the outer side of the output end of the motor 91. The rotating shaft 92 is rotatably connected to the worktable 3. A push rod 93 is slidably sleeved inside the rotating shaft 92. An impact block 94 is fixedly connected to the top of the push rod 93. The impact block 94 contacts the lower mold 4. There are multiple impact blocks 94, which are evenly distributed on the outer side of the rotating shaft 92. By designing multiple impact blocks... The impact block 94 can impact the lower mold 4 at multiple positions. The ejector rod 93 is internally fixedly connected to the fixing rod 95.

By pulling out the plug 86, lubricating oil can be added into the flow channel 85, which can replenish the lubricating oil into the sponge sleeve 84.

[0027] After the workpiece is injection molded, the motor 91 starts working. The output end of the motor 91 can drive the rotating shaft 92 to rotate. The rotating shaft 92 drives the ejector rod 93 and the impact block 94 to rotate. The rotating impact block 94 will contact the lower mold 4 and be squeezed to slide along the rotating shaft 92. The ejector rod 93 will drive the fixing rod 95 to slide along the fixing block 97. The ejector rod 93 will squeeze the spring 96. The rotating impact block 94 can impact the lower mold 4 and make the lower mold 4 vibrate. This can avoid the problem of material sticking to the mold and being difficult to remove during demolding.
