Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the front die slide of a mold, in particular to a fine gate pouring four-side front die slide structure for the upper shell of a four-way charger of an unmanned aerial vehicle (UAV). Background Technique
[0002] In the prior art, the front die slide structure usually refers to a component used to form specific shapes or features on plastic parts in the design of plastic molds. These structures can be sliders, slides, angled lifters, etc. They move during the mold opening and closing process to form the internal or external shape of the plastic part. The fine gate pouring four sides of the upper shell of the UAV four-way charger means that in the design of a plastic injection mold, a fine gate system is used to injection-mold the upper shell of the charger, and gates are set on the four sides of the mold. However, there are certain drawbacks when the devices in the prior art are used. For example, in the injection mold for the upper shell of an automotive key recorded in the patent publication number CN218615216U, it includes an upper mold base, a lower mold base, an upper mold core and a lower mold core, and also includes a key insert block. The key insert block includes a column part, and a key forming surface is provided at the top of the column part.
[0003] Although the above structure can heat the detailed positions to make the injection at the detailed positions more sufficient, which is beneficial to the production of injection-molded parts, when it is used for the UAV charger, the mold at the side slot position of the main body of the upper shell of the charger will catch the side of the UAV, resulting in inapplicability of normal demolding. Forced demolding will cause scratches on the surface of the product. In addition, for some molds with the slide structure in the upper mold base, there is no design to reduce the friction surface and lower the temperature, resulting in problems such as slider wear and thermal expansion. Content of the Utility Model
[0004] The purpose of the utility model is to provide a fine gate pouring four-side front die slide structure for the upper shell of a UAV four-way charger to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] The fine gate pouring four-side front die slide structure for the upper shell of a UAV four-way charger includes a slide structure detachably connected to the lower surface of the front die panel. A front die connecting plate is nested and connected to the outer surface of the slide structure. A front die plate is detachably connected to the lower surface of the slide structure and located below the front die connecting plate. A front die core is embedded and connected to the lower surface of the front die plate. The slide structure includes a front die slide lifter, a front die slide, a slider, and a connecting block. The front die slide is movably connected inside the front die slide lifter. A slider is fixedly connected to the end of the front die slide. A connecting block is slidably connected to the outer surface of the slider.
[0007] Furthermore, a low-temperature runner is provided on the side surface of the front template on the outer side of the slider structure. The low-temperature runner is a spiral part near the slider structure. A high-temperature runner is provided on the side surface of the front template on the outer side of the slider structure. The high-temperature runner is far away from the slider structure. An embedding groove is provided on the lower surface of the front template near the slider. The embedding groove matches the front die core.
[0008] Furthermore, a chute is provided on the outer surface of the slider, and the slider is a bevel surface that matches the connecting block. A groove is provided on the inner surface of the connecting block. A self-lubricating ball is rotatably connected inside the groove. A limiting plate is detachably connected to the outer surface of the groove.
[0009] Furthermore, a bolt is threadedly connected to the upper surface of the front die slider lifter. The front die slider lifter is detachably connected to the front die panel through the bolt.
[0010] Furthermore, a limiting post is fixedly connected to the side surface of the front die core on the outer side of the connecting block. The connecting block is slidably connected to the limiting post. The upper surface of the connecting block is slidably connected to the front template.
[0011] Furthermore, a side die is fixedly connected to the outer surface of the connecting block near the front die core.
[0012] Preferably, a side die hole is provided on the outer surface of the front die core on one side of the side die. The side die matches the side die hole.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] The slider is a bevel surface. When the slider rises, the connecting block moves outward. The chute contacts the rotatable self-lubricating ball. The limiting plate is used to limit the self-lubricating ball, changing the sliding friction into rolling friction. The wear between the friction surface and between the slider and the connecting block can be reduced through the self-lubricating ball. The low-temperature runner is close to the slider structure. While cooling the main body of the charger upper shell, the spiral part cools the periphery of the slider structure, effectively reducing the temperature around the slider structure and reducing the thermal expansion and deformation caused by temperature changes.
[0015] The connecting block is limited by the limiting post and the front template. When moving outward, the side die and the side die hole are separated, preventing the side die from jamming the side slot hole position of the charger upper shell main body during demolding and preventing the side die from scratching the side of the charger upper shell main body during demolding.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, the fine-gate four-side front mold slider structure of the drone four-way charger upper shell includes a slider structure 4 detachably connected to the lower surface of the front mold panel 1. The outer surface of the slider structure 4 is nested and connected with a front mold connecting plate 2. The outer surface of the slider structure 4 is detachably connected to the lower surface of the front mold connecting plate 2 with a front template 3. The lower surface of the front template 3 is embedded and connected with a front mold core 6. The slider structure 4 includes a front mold slider lifter 401, a front mold slider 402, a slide block 403, and a connecting block 405. The front mold slider lifter 401 is movably connected to the front mold slider 402 inside. The end of the front mold slider 402 is fixedly connected to the slide block 403. The outer surface of the slide block 403 is slidably connected to the connecting block 405.
[0024] Specifically, when the slider structure 4 is in use, the front mold slider lifter 401 drives the front mold slider 402 to contract, causing the slider 403 to move upward. When the slider 403 moves, an obliquely outward acting force is exerted on the connecting block 405, causing the connecting block 405 to move outward, facilitating the demolding of the charger upper shell body 7 in the later stage. At the same time, the friction surface between the slider 403 and the connecting block 405 is treated to reduce friction, effectively alleviating the wear between the slider 403 and the connecting block 405. Moreover, the setting of the spiral part 304 can more effectively control the mold temperature, improve the molding quality of plastic parts, and reduce deformation.
[0025] Embodiment 1
[0026] As Figures 1 - 4 shown, a low-temperature runner 302 is provided on the side surface of the front template 3 on the outer side of the slider structure 4. The position of the low-temperature runner 302 close to the slider structure 4 is the spiral part 304. A high-temperature runner 303 is provided on the side surface of the front template 3 on the outer side of the slider structure 4. The high-temperature runner 303 is far from the slider structure 4. An embedding groove 301 is provided on the lower surface of the front template 3 close to the slider 403, and the embedding groove 301 matches the front mold core 6.
[0027] In this embodiment, the low-temperature runner 302 is close to the slider structure 4. While cooling the charger upper shell body 7, the spiral part 304 cools the periphery of the slider structure 4, effectively reducing the temperature around the slider structure 4 and reducing thermal expansion and deformation caused by temperature changes. The high-temperature runner 303 is close to the upper surface position of the charger upper shell body 7. There are many holes on the upper surface of the charger upper shell body 7, and it is heated by the inflow of external media. During injection molding, it can ensure that the molten material at the holes flows smoothly, and at the same time, it can control the temperature of other parts, avoid forming burrs at the mold parting surface, and improve the injection molding quality and work efficiency.
[0028] As Figure 5 shown, a bolt 5 is threadedly connected to the upper surface of the front mold slider lifter 401, and the front mold slider lifter 401 is detachably connected to the front mold panel 1 through the bolt 5.
[0029] In this embodiment, the slider structure 4 is fixed to the lower surface of the front mold panel 1 through the bolt 5.
[0030] Embodiment 2
[0031] On the basis of Embodiment 1, in order to make up for the problem of inconvenient reduction of the friction surface in Embodiment 1.
[0032] As Figures 1 - 5As shown in the figure, a chute 404 is provided on the outer surface of the slider 403, and the slider 403 has an inclined surface that matches the connecting block 405. A groove 406 is provided on the inner surface of the connecting block 405, and a self-lubricating ball 408 is rotatably connected inside the groove 406. A limiting plate 407 is detachably connected to the outer surface of the groove 406.
[0033] In this embodiment, the slider 403 has an inclined surface. When the slider 403 rises, the connecting block 405 moves outward. The chute 404 contacts the rotatable self-lubricating ball 408. The limiting plate 407 is used to limit the self-lubricating ball 408, changing the sliding friction into rolling friction. The self-lubricating ball 408 can reduce the friction surface and the wear between the slider 403 and the connecting block 405.
[0034] As Figures 1 - 5 shown in the figure, a limiting post 601 is fixedly connected to the side surface of the front mold core 6 on the outer side of the connecting block 405. The connecting block 405 is slidably connected to the limiting post 601. The upper surface of the connecting block 405 is slidably connected to the front template 3. A side mold 603 is fixedly connected to the outer surface of the connecting block 405 near the front mold core 6. A side mold hole 602 is provided on the outer surface of the front mold core 6 on one side of the side mold 603. The side mold 603 matches the side mold hole 602.
[0035] In this embodiment, the connecting block 405 is limited by the limiting post 601 and the front template 3. When moving outward, the side mold 603 and the side mold hole 602 are separated, preventing the side mold 603 from getting stuck in the side slot 701 position of the charger upper shell main body 7 during demolding.
