Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically to a molding die for a toolbox. Background Technology

[0002] In modern industrial production, toolboxes, as commonly used containers for storing and carrying tools, are experiencing a continuous increase in market demand. This has placed higher demands on the efficient and high-quality molding and manufacturing of toolboxes. Mold forming technology, due to its ability to achieve mass production and its high dimensional accuracy control, has become one of the important methods for manufacturing toolboxes.

[0003] However, in the use of existing toolbox molding dies, after the workpiece is processed, it is very easy for it to stick to the inner wall of the lower mold. This phenomenon is caused by a combination of factors. On the one hand, due to the thermal expansion and contraction characteristics of the material during processing, the workpiece may adhere tightly to the inner wall of the lower mold during the cooling and shrinkage phase. On the other hand, the pressure applied during mold processing and some physical adsorption properties of the material itself can also cause the workpiece to stick to the inner wall of the mold. Once the workpiece sticks to the lower mold, it becomes very difficult to demold. Usually, it is necessary to manually separate the workpiece from the lower mold using simple tools, such as pry bars. This demolding method not only consumes a lot of manpower and time, seriously affecting production efficiency, but also, the use of improper tools for demolding can easily cause scratches, deformation, and other damage to the workpiece, resulting in inconsistent product quality, increased scrap rate, and increased production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a toolbox forming mold that solves the problem that the workpiece and the inner wall of the lower mold are prone to sticking after the mold has finished processing the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A toolbox forming mold includes a frame, a telescopic cylinder fixedly mounted on the top of the frame, a movable block fixedly mounted on the surface of the telescopic cylinder, an upper mold fixedly mounted on the bottom of the movable block, and a lower mold fixedly mounted on the inner side of the frame; it also includes a movable component for scraping the inner wall of the lower mold; and a moving component for abutting the forming mold; the movable component includes: a fixed frame fixedly mounted on the inner side of the frame, a drive motor fixedly mounted on the outer side of the fixed frame, a cam fixedly mounted on the output surface of the drive motor, one end of a movable rod hinged to the surface of the cam, a slider slidably connected to the top of the fixed frame, a connecting block fixedly mounted on the top of the slider, the other end of the movable rod hinged to the outer side of the connecting block, a movable plate hinged to the surface of the connecting block, a connecting plate hinged to the surface of the movable plate, the connecting plate penetrating the slider, and an insert plate fixedly mounted on the surface of the connecting plate, the insert plate being disposed inside the lower mold.

[0007] Preferably, a spiral spring one is fixedly installed at the connection between the movable plate and the connecting block, and a spiral spring two is fixedly installed at the connection between the movable plate and the connecting plate.

[0008] Preferably, the moving component includes: a stop plate, the stop plate being fixedly installed on the outer wall of the movable block; a rotating shaft being rotatably connected inside the frame; a sliding rod being fixedly installed on the surface of the rotating shaft; a telescopic rod being fixedly installed on the surface of the sliding rod; and a fixing spring being fixedly installed inside the telescopic rod.

[0009] Preferably, a threaded rod is fixedly installed inside the rotating shaft, and an abutment shaft is threadedly connected to the surface of the threaded rod. The abutment shaft passes through the interior of the frame, and an abutment plate is fixedly installed on the surface of the abutment shaft. The abutment plate is slidably connected to the interior of the lower mold.

[0010] Preferably, the active components are provided in two sets, and both sets of active components are symmetrically arranged with the center line of the frame as the axis of symmetry.

[0011] Preferably, the surface of the fixing frame is provided with a sliding groove, and the surface of the slider is provided with a groove.

[0012] Preferably, the surface of the rotating shaft is provided with an arc-shaped groove, and the surface of the frame is provided with a strip-shaped groove.

[0013] By employing the above technical solution, this utility model provides a molding die for a toolbox. It possesses at least the following beneficial effects:

[0014] (1) By setting the movable components, after processing, the cam is driven to rotate by starting the drive motor. When the cam rotates, it will abut against the top of the connecting plate and drive the movable plate and the insert plate to slide down through the connecting plate. When the insert plate slides down, it will insert into the inside of the lower mold. When the cam rotates, it will also abut against the connecting block through the movable rod and drive the slider to slide at the top of the fixed frame. When the slider slides, it will drive the insert plate set at the top to slide. When the insert plate slides, it will slide on the inner wall of the lower mold to prevent the workpiece from sticking and avoid damage to the workpiece when taking it out. This improves the demolding efficiency and ensures product quality.

[0015] (2) By setting up the moving component, after processing is completed, the telescopic cylinder drives the movable block to move upward. When the movable block moves upward, it will release the resistance to the telescopic rod. At this time, the telescopic rod will reset under the action of the fixed spring. When the telescopic rod resets, it will drive the sliding rod to slide on the surface of the rotating shaft again, causing the rotating shaft and the threaded rod to rotate in the opposite direction. When the threaded rod rotates in the opposite direction, it will drive the abutting shaft and the abutting plate to slide upward. When the abutting plate moves upward, it will abut against the bottom of the forming mold and push the mold that has been formed to move upward inside the lower mold. This prevents the workpiece from being stuck in the mold and unable to be removed after the mold is processed. It avoids the possibility of damaging the workpiece due to forced removal, improves the convenience of demolding, and ensures the continuity of processing. Attached Figure Description

Detailed Implementation

[0024] 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. Example 1

[0025] A toolbox molding die, such as Figures 1-3 As shown, it includes a frame 1, a telescopic cylinder 2 is fixedly installed on the top of the frame 1, a movable block 3 is fixedly installed on the surface of the telescopic cylinder 2, an upper mold 4 is fixedly installed on the bottom of the movable block 3, and a lower mold 5 is fixedly installed on the inner side of the frame 1.

[0026] It also includes a movable component 6 for scraping the inner wall of the lower mold 5;

[0027] The movable component 7 is used to abut against the forming mold;

[0028] First, the active component 6 includes: a fixed frame 61, which is fixedly installed on the inner side of the frame 1; a drive motor 62 is fixedly installed on the outer side of the fixed frame 61; a cam 63 is fixedly installed on the output surface of the drive motor 62; one end of a movable rod 64 is hinged to the surface of the cam 63; a slider 65 is slidably connected to the top of the fixed frame 61; a connecting block 66 is fixedly installed on the top of the slider 65; the other end of the movable rod 64 is hinged to the outer side of the connecting block 66; a movable plate 67 is hinged to the surface of the connecting block 66; a connecting plate 68 is hinged to the surface of the movable plate 67; the connecting plate 68 passes through the slider 65; and an insert plate 69 is fixedly installed on the surface of the connecting plate 68. The insert plate 69 is located inside the lower mold 5, and the adhesion between the workpiece and the lower mold 5 can be reduced by sliding the insert plate 69.

[0029] Secondly, a spiral spring 610 is fixedly installed at the connection between the movable plate 67 and the connecting block 66, and a spiral spring 611 is fixed at the connection between the movable plate 67 and the connecting plate 68. The resetting effect of the movable plate 67 and the connecting plate 68 can be achieved through the spiral spring 610 and the spiral spring 611.

[0030] In this embodiment, by setting the movable component 6, after processing is completed, the drive motor 62 is started to drive the cam 63 to rotate. When the cam 63 rotates, it will abut against the top of the connecting plate 68, and the connecting plate 68 will drive the movable plate 67 and the insert plate 69 to slide downward. When the insert plate 69 slides downward, it will be inserted into the interior of the lower mold 5. When the cam 63 rotates, it will also abut against the connecting block 66 through the movable rod 64 and drive the slider 65 to slide at the top of the fixed frame 61. When the slider 65 slides, it will drive the insert plate 69 set at the top to slide. When the insert plate 69 slides, it will slide on the inner wall of the lower mold 5 to prevent the workpiece from sticking and avoid damage to the workpiece when it is taken out, thereby improving the demolding efficiency and ensuring product quality. Example 2

[0031] like Figures 4-6 As shown, the movable component 7 includes: a stop plate 71, which is fixedly installed on the outer wall of the movable block 3; a rotating shaft 72 is rotatably connected inside the frame 1; a slide rod 73 is fixedly installed on the surface of the rotating shaft 72; a telescopic rod 74 is fixedly installed on the surface of the slide rod 73; and a fixing spring 75 is fixedly installed inside the telescopic rod 74.

[0032] Furthermore, a threaded rod 76 is fixedly installed inside the rotating shaft 72, and an abutment shaft 77 is threadedly connected to the surface of the threaded rod 76. The abutment shaft 77 passes through the interior of the frame 1, and an abutment plate 78 is fixedly installed on the surface of the abutment shaft 77. The abutment plate 78 is slidably connected to the interior of the lower mold 5. The molding mold can be pushed to move upward inside the lower mold 5 by sliding the abutment plate 78.

[0033] There are two sets of active components 6, and both sets of active components 6 are symmetrically arranged with the center line of the frame 1 as the axis of symmetry.

[0034] Furthermore, the surface of the fixing frame 61 is provided with a sliding groove 6100, which allows the slider 65 to slide on the surface of the fixing frame 61. The surface of the slider 65 is provided with a groove 650, which allows the connecting plate 68 to move stably.

[0035] Finally, an arc-shaped groove 720 is provided on the surface of the rotating shaft 72. The rotating shaft 72 can be rotated when the slide rod 73 slides through the arc-shaped groove 720 on the surface of the rotating shaft 72. A strip-shaped groove 10 is provided on the surface of the frame 1. The strip-shaped groove 10 on the surface of the frame 1 can facilitate the movement of the abutment plate 71 through the frame 1 to the top of the telescopic rod 74.

[0036] In this embodiment, by setting the moving component 7, after processing is completed, the telescopic cylinder 2 drives the movable block 3 to move upward. When the movable block 3 moves upward, it will release the resistance to the telescopic rod 74. At this time, the telescopic rod 74 will reset under the action of the fixed spring 75. When the telescopic rod 74 resets, it will drive the slide rod 73 to slide again on the surface of the rotating shaft 72, causing the rotating shaft 72 and the threaded rod 76 to rotate in the opposite direction. When the threaded rod 76 rotates in the opposite direction, it will drive the abutment shaft 77 and the abutment plate 78 to slide upward. When the abutment plate 78 moves upward, it will abut against the bottom of the forming mold and push the formed mold to move upward inside the lower mold 5. This prevents the workpiece from being stuck in the mold and unable to be removed after the mold is processed because it is too tightly attached to the inner wall of the lower mold 5. This avoids the possibility of damaging the workpiece due to forced removal, improves the convenience of demolding, and ensures the continuity of processing.

[0037] In use, the toolbox forming mold of this utility model can be driven by activating the telescopic cylinder 2 to move the movable block 3 downward. When the movable block 3 moves downward, it will drive the upper mold 4 downward. When the upper mold 4 moves downward, it will move the interior of the lower mold 5 for processing. After processing, the drive motor 62 can be activated to drive the cam 63 to rotate. When the cam 63 rotates, it will abut against the top of the connecting plate 68, and through the connecting plate 68, it will drive the movable plate 67 and the insert plate 69 to slide downward. When the insert plate 69 slides downward, it will insert into the interior of the lower mold 5. When the cam 63 rotates, it will also abut against the connecting block 66 through the movable rod 64 and drive the slider 65 to slide at the top of the fixed frame 61. When the slider 65 slides, it will drive the insert plate 69 set at the top to slide. When sliding, the cam 63 slides on the inner wall of the lower mold 5. When the drive motor 62 stops starting, the cam 63 releases its contact with the connecting plate 68, causing the connecting plate 68 and the movable plate 67 to reset under the action of the first scroll spring 610 and the second scroll spring 611, which in turn drives the insertion plate 69 to reset. By using the insertion plate 69 to slide inside the lower mold 5, the workpiece can be prevented from sticking. After the mold is processed, the workpiece may stick to the inner wall of the lower mold 5 for various reasons. The insertion plate 69 sliding inside the lower mold 5 can apply a certain external force to the workpiece through its own movement, breaking the possible adhesion between the workpiece and the inner wall of the mold, thereby preventing the workpiece from being difficult to demold smoothly, avoiding damage to the workpiece when taking it out, improving demolding efficiency, and ensuring product quality.

[0038] When the movable block 3 slides downward, it also causes the abutment plate 71 to slide downward. When the abutment plate 71 slides downward, it abuts against the top of the telescopic rod 74, causing the telescopic rod 74 to retract. When the telescopic rod 74 retracts, it causes the slide rod 73 to slide on the surface of the rotating shaft 72, causing the rotating shaft 72 to rotate through the arc groove 720. When the rotating shaft 72 rotates, it causes the threaded rod 76 to rotate. When the threaded rod 76 rotates, it causes the abutment shaft 77 to slide downward. When the abutment shaft 77 slides downward, it causes the abutment plate 78 to slide downward. After processing is completed, the telescopic cylinder 2 causes the movable block 3 to move upward. When the movable block 3 moves upward, it releases the abutment against the telescopic rod 74. At this time, the telescopic rod 74 acts as a retaining spring 75. When the telescopic rod 74 resets, it will cause the sliding rod 73 to slide again on the surface of the rotating shaft 72, causing the rotating shaft 72 and the threaded rod 76 to rotate in the opposite direction. When the threaded rod 76 rotates in the opposite direction, it will cause the abutment shaft 77 and the abutment plate 78 to slide upward. When the abutment plate 78 moves upward, it will abut against the bottom of the forming mold and push the formed mold upward inside the lower mold 5. This prevents the workpiece from being difficult to remove from the lower mold 5 after the mold is processed because it is tightly attached to the inner wall of the lower mold 5, there is a certain suction force or other obstacles. This prevents the workpiece from getting stuck in the mold and avoids the possibility of damaging the workpiece due to forced removal, improves the convenience of demolding, and ensures the continuity of processing.
