Description

Technical Field

[0001] The present application relates to the technical field of molds, and in particular to a dust bucket inner shell molding mold. Background Art

[0002] Mold manufacturing technology plays an important role in the molding and manufacturing of various products, especially for plastic products.

[0003] As a key component of cleaning equipment, the inner shell of the dust collector has a direct impact on the performance and cost of the final product due to its molding efficiency and quality. In the current market, traditional molding molds generally face problems such as cumbersome operation and low efficiency in the demoulding process. Figure 1 Since the inner shell of the dust collector needs to form the transverse hole 16 and the vertical hole 17 at the same time, the mold needs to use transverse inserts and vertical inserts to cooperate. In the demolding process after the molding operation is completed, these molds usually use a single demolding method, such as relying only on transverse or longitudinal movement. This is inadequate when dealing with the inner shell of the dust collector with a complex shape. It is difficult to ensure the smoothness of demolding and also affects the quality of the product. Therefore, how to simplify the demolding operation, improve efficiency, and reduce product damage has become a technical problem that needs to be solved in this field. Summary of the invention

[0004] In order to simplify the demolding operation, improve the demolding efficiency, and reduce product damage, the present application provides a dust bucket inner shell molding mold.

[0005] The present application provides a dust collecting bucket inner shell forming mold, which adopts the following technical solution: A dust bucket inner shell forming mold, comprising an upper template and a lower template that cooperate with each other, the upper template is provided with an upper mold core, the lower template is provided with a lower mold core, the upper mold core is provided with a groove on the surface facing the lower mold core, and the lower mold core is provided with a protrusion on the surface facing the upper mold core. When the upper template and the lower template are molded together, the protrusion and the groove surround a forming mold cavity to form the inner shell of the dust bucket, the lower mold core is provided with a transverse insert for forming transverse holes and a vertical insert for forming vertical holes, and the lower template is provided with a demolding mechanism. When the inner shell of the dust bucket is formed, the upper template and the lower template are separated, and the formed inner shell of the dust bucket remains on the protrusion, and the demolding mechanism is used to simultaneously extract the vertical insert vertically from the inner shell of the dust bucket and extract the transverse insert horizontally from the inner shell of the dust bucket.

[0006] By adopting the above technical scheme, the upper template supports the upper mold core, and the lower template supports the lower mold core. When the upper template and the lower template are molded together, the grooves and the protrusions surround the molding cavity of the dust bucket inner shell, and the molten plastic flows into the molding cavity to cool and solidify to complete the injection molding process of the dust bucket inner shell, wherein the horizontal insert forms the horizontal hole, and the vertical insert forms the vertical hole. When the molding operation of the dust bucket inner shell is completed, the upper template and the lower template are separated, and the molded dust bucket inner shell remains on the protrusions. The demolding mechanism simultaneously pulls out the vertical insert from the dust bucket inner shell and the horizontal insert from the dust bucket inner shell horizontally, thereby simplifying the demolding operation, improving the demolding smoothness, and improving the demolding efficiency. At the same time, it can reduce the damage to the dust bucket inner shell during the demolding process.

[0007] Preferably, the demolding mechanism includes a movable plate, a driving member, a vertical top member and a horizontal pushing member, the movable plate is movably inserted into the lower mold core, the protrusion is arranged on the movable plate, the driving member is arranged on the lower mold core to drive the movable plate to move toward the direction close to the lower template, the vertical top member and the horizontal pushing member are arranged on the lower template, when the driving member drives the movable plate to move toward the direction close to the lower template, the vertical top member vertically supports the inner shell of the dust bucket after molding, and the horizontal pushing member laterally pulls the horizontal insert out of the horizontal hole.

[0008] By adopting the above technical scheme, when it is necessary to demold the formed dust bucket inner shell, the driving member drives the movable plate to move toward the direction close to the lower template, and the vertical top member vertically supports the dust bucket inner shell to make the dust bucket inner shell detach from the protrusion. At the same time, in the process of the dust bucket inner shell detaching from the protrusion, the vertical insert is vertically pulled out from the dust bucket inner shell, and the horizontal push member pulls the horizontal insert out of the horizontal hole under the drive of the movement of the movable plate. The extraction operation of the vertical insert and the extraction operation of the horizontal insert are performed simultaneously, which is beneficial to improving the demolding efficiency, and only one driving member is needed to complete it, thereby simplifying the mold structure.

[0010] By adopting the above technical solution, the vertical push rod is vertically fixedly connected to the lower template, and the upper end of the vertical push rod presses against the bottom of the inner shell of the dust bucket. When the driving member drives the movable plate to move toward the lower template, the protrusion moves vertically downward with the movement of the movable plate to achieve the separation of the inner shell of the dust bucket and the protrusion. At the same time, the vertical insert also moves vertically downward with the movement of the protrusion to achieve the extraction of the vertical insert from the vertical hole.

[0011] Preferably, the transverse push member includes a rotating seat and a tilting rod, the rotating seat is fixedly connected to the lower template, the lower end of the tilting rod is rotatably connected to the rotating seat, the upper end of the tilting rod is fixedly connected to the transverse insert, the tilting rod is movably inserted into the movable plate, and the tilting rod is tilted from bottom to top in a direction away from the transverse hole.

[0012] By adopting the above technical solution, the tilting rod is connected to the lower template through the rotating seat. When the movable plate moves toward the lower template, the downward movement of the movable plate drives the tilting rod to rotate, and the upper end of the tilting rod moves in the direction away from the transverse hole, so that the tilting rod drives the transverse insert connected to its upper end to be pulled out from the transverse hole.

[0013] Preferably, the driving member is configured as a driving rod, which is horizontally fixedly connected to the edge of the movable plate, and the driving rod is passed through the side wall of the lower mold core, and the lower mold core is vertically provided with a first avoidance groove for the driving rod to move vertically up and down.

[0014] By adopting the above technical solution, when demoulding operation is required, the staff presses the driving rod vertically downward so that the driving rod drives the movable plate to move vertically downward. The first avoidance groove avoids the movement of the driving rod, and the demoulding process is simple and convenient.

[0015] Preferably, a stabilizing block is provided on the other side of the movable plate relative to the driving rod, the stabilizing block abuts against the side wall of the inner shell of the formed dust collecting bucket, and the lower mold core is vertically provided with a second avoidance groove for the stabilizing block to move vertically up and down.

[0016] By adopting the above technical solution, when the driving rod drives the movable plate to move for demolding operation, the movable plate drives the stabilizing block to move synchronously, and the stabilizing block abuts against the side wall of the inner shell of the dust bucket after molding, which is beneficial to improve the stability of the demolding operation of the inner shell of the dust bucket, thereby helping to improve the smoothness of demolding, and the second avoidance groove avoids the movement of the stabilizing block.

[0017] Preferably, the demoulding mechanism further comprises a reset member, which is arranged on the lower template and is used to push the movable plate back to its original position after the demoulding operation is completed.

[0018] By adopting the above technical solution, the reset member pushes the movable plate back to its original position after the demoulding operation is completed, so as to facilitate the molding operation of the next dust collecting bucket inner shell.

[0019] Preferably, the reset member is configured as a reset spring, the reset spring is vertically fixedly connected to the lower template, the upper end of the reset spring is fixedly connected to the lower end of the movable plate, the reset spring is passed through the lower mold core, and when the reset spring is in a natural state, the movable plate is in its original position when no demolding operation is performed.

[0020] By adopting the above technical solution, when the return spring is in a natural state, the movable plate is in its original position when the demolding operation is not performed. At this time, the injection molding operation of the dust bucket inner shell can be carried out. When the molding of the dust bucket inner shell is completed, the driving rod drives the movable plate to move vertically downward for the demolding operation. At this time, the return spring is in a compressed state. When the dust bucket inner shell is taken out of the mold, the restoring force of the return spring pushes the movable plate back to its original position to facilitate the injection molding operation of the next dust bucket inner shell.

[0021] Preferably, the upper die core is provided with an upper cooling water channel surrounding the groove.

[0022] By adopting the above technical solution, the upper cooling water channel cools the injection molding process of the inner shell of the dust collecting bucket, which is beneficial to improving the molding efficiency of the inner shell of the dust collecting bucket.

[0023] Preferably, the lower mold core is provided with a lower cooling water channel, and the lower cooling water channel is located below the protrusion.

[0024] By adopting the above technical solution, the bottom of the protrusion is used to form the opening position of the inner shell of the dust bucket. The opening position of the inner shell of the dust bucket has an edge, so the thickness of this position is relatively thick, and the lower cooling water channel performs double cooling on this position, which is beneficial to further improve the molding efficiency of the inner shell of the dust bucket.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging a movable plate, a driving member, a vertical top member and a horizontal push member, when it is necessary to demould the formed dust bucket inner shell, the driving member drives the movable plate to move toward the direction close to the lower template, and the vertical top member vertically supports the dust bucket inner shell to make the dust bucket inner shell separate from the protrusion. At the same time, in the process of the dust bucket inner shell separating from the protrusion, the vertical insert is vertically drawn out from the dust bucket inner shell, and the horizontal push member draws out the horizontal insert from the horizontal hole under the drive of the movement of the movable plate. The extraction operation of the vertical insert and the extraction operation of the horizontal insert are performed simultaneously, which is beneficial to improving the demoulding efficiency, and only one driving member is needed to complete it, thereby simplifying the mold structure.

[0026] 2. By setting a rotating seat and a tilting rod, the tilting rod is connected to the lower template through the rotating seat. When the movable plate moves toward the lower template, the downward movement of the movable plate drives the tilting rod to rotate, and the upper end of the tilting rod moves in the direction away from the transverse hole, so that the tilting rod drives the transverse insert connected to its upper end to be pulled out from the transverse hole.

[0027] 3. By setting a return spring, when the return spring is in a natural state, the movable plate is in its original position when the demolding operation is not performed. At this time, the injection molding operation of the inner shell of the dust bucket can be carried out. When the inner shell of the dust bucket is molded, the driving rod drives the movable plate to move vertically downward for demolding operation. At this time, the return spring is in a compressed state. When the inner shell of the dust bucket is taken out of the mold, the restoring force of the return spring pushes the movable plate back to its original position to facilitate the injection molding operation of the next inner shell of the dust bucket.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 2-6 This application is described in further detail.

[0036] The present application embodiment discloses a dust collecting bucket inner shell forming mold, referring to Figure 2 , including an upper template 1 and a lower template 2 that cooperate with each other, the upper template 1 and the lower template 2 are arranged in parallel, the upper template 1 is provided with an upper mold core 3 on the plate surface facing the lower template 2, and the lower template 2 is provided with a lower mold core 4 on the plate surface facing the upper template 1, refer to Figure 3 and Figure 4 A groove 5 is provided on the surface of the upper mold core 3 facing the lower mold core 4, and a protrusion 6 is provided on the surface of the lower mold core 4 facing the upper mold core 3. When the upper mold plate 1 and the lower mold plate 2 are molded together, the protrusion 6 and the groove 5 surround a molding cavity of the inner shell of the dust collecting bucket.

[0037] Reference Figure 2 The upper mold plate 1 is fixedly provided with a glue injection tube 18. One end of the glue injection tube 18 passes through the upper mold plate 1 and the upper mold core 3 and is connected to the molding cavity. The other end of the glue injection tube 18 is connected to the injection molding equipment (not shown in the figure). When the dust bucket inner shell needs to be injection molded, the injection molding equipment injects the molten plastic into the molding cavity through the glue injection tube 18. The molten plastic in the molding cavity is cooled and solidified to obtain the dust bucket inner shell. Figure 3 and Figure 4 The upper mold core 3 is provided with an upper cooling water channel 14 around the groove 5 to improve the efficiency of cooling and solidification molding. Furthermore, the lower mold core 4 is provided with a lower cooling water channel 15, and the lower cooling water channel 15 is located below the protrusion 6. Since the bottom of the protrusion 6 is used to form the opening position of the inner shell of the dust bucket, the opening position of the inner shell of the dust bucket has an edge, and the thickness of this position is relatively thick, the lower cooling water channel 15 cooperates with the upper cooling water channel 14 to perform double cooling on this position to further improve the molding efficiency of the inner shell of the dust bucket.

[0038] Reference Figure 3 The lower mold core 4 is provided with a transverse insert 7 for forming a transverse hole 16 and a vertical insert 8 for forming a vertical hole 17. At the same time, the lower template 2 is provided with a demoulding mechanism 9. When the inner shell of the dust bucket is formed, the upper template 1 and the lower template 2 are separated, and the formed inner shell of the dust bucket remains on the protrusion 6. The demoulding mechanism 9 is used to simultaneously pull out the vertical insert 8 vertically from the inner shell of the dust bucket and pull out the transverse insert 7 horizontally from the inner shell of the dust bucket.

[0039] Reference Figure 4 , Figure 5 and Figure 6 The demolding mechanism 9 includes a movable plate 91, a driving member, a vertical top member and a horizontal push member 94. Specifically, the movable plate 91 is horizontally arranged, and the movable plate 91 is movably arranged inside the lower mold core 4. The protrusion 6 is fixedly arranged on the movable plate 91. The driving member is arranged on the lower mold core 4 to drive the movable plate 91 to move toward the direction close to the lower template 2. The vertical top member and the horizontal push member 94 are arranged on the lower template 2. When the driving member drives the movable plate 91 to move toward the direction close to the lower template 2, the vertical top member vertically supports the formed dust bucket inner shell to separate the formed dust bucket inner shell from the protrusion 6, and the vertical insert 8 is pulled out from the vertical hole 17 of the dust bucket inner shell. At the same time, the horizontal push member 94 horizontally pulls the horizontal insert 7 out of the horizontal hole 16, which simplifies the demolding operation, has strong demolding fluency, improves the demolding efficiency, and can reduce the damage to the dust bucket inner shell during the demolding process.

[0040] Reference Figure 4 and Figure 5 The vertical top member includes a plurality of vertical top rods 93, which are vertically fixedly connected to the lower template 2, and the upper ends of the plurality of vertical top rods 93 are in contact with the bottom of the formed dust bucket inner shell. When the driving member drives the movable plate 91 to move vertically downward, the plurality of vertical top rods 93 support the dust bucket inner shell, and the protrusion 6 moves vertically downward with the movement of the movable plate 91 to achieve the separation of the dust bucket inner shell and the protrusion 6, and in the process of separating the dust bucket inner shell and the protrusion 6, the vertical insert 8 is simultaneously pulled out from the vertical hole 17 of the dust bucket inner shell.

[0041] Reference Figure 4 and Figure 5 The driving member is set as a driving rod 92, which is horizontally fixedly connected to the edge of the movable plate 91. In this embodiment, the number of driving rods 92 is set to two, and the two driving rods 92 are arranged in parallel, and the two driving rods 92 are penetrated from the side wall of the lower mold core 4 to form a handle. At the same time, the lower mold core 4 is vertically provided with a first avoidance groove 10 for the driving rod 92 to move vertically up and down. When demoulding operation is required, the staff presses the driving rod 92 downward to make the driving rod 92 drive the movable plate 91 to move vertically downward, and the operation is simple and convenient.

[0042] Reference Figure 3 The other side of the movable plate 91 relative to the driving rod 92 is fixed with a stabilizing block 11, which abuts against the side wall of the inner shell of the dust bucket after molding. At the same time, the lower mold core 4 is vertically provided with a second avoidance groove 12 for the stabilizing block 11 to move vertically up and down. When the driving rod 92 drives the movable plate 91 to move vertically downward, the stabilizing block 11 moves vertically downward synchronously, and the stabilizing block 11 always abuts against the side wall of the inner shell of the dust bucket, so as to improve the stability of the demoulding operation of the inner shell of the dust bucket.

[0043] Reference Figure 4 and Figure 6 The horizontal push member 94 includes a rotating seat 941 and a tilting rod 942. The rotating seat 941 is fixedly connected to the plate surface of the lower mold plate 2 facing the lower mold core 4. The lower end of the tilting rod 942 is rotatably connected to the rotating seat 941. The upper end of the tilting rod 942 is fixedly connected to the bottom of the horizontal insert 7. The tilting rod 942 is movably arranged on the movable plate 91. It is worth mentioning that the tilting rod 942 tilts from bottom to top in a direction away from the horizontal hole 16. When the driving rod 92 drives the movable plate 91 to move vertically downward, the movable plate 91 pushes the upper end of the tilting rod 942 to rotate in a direction away from the horizontal hole 16, so that the upper end of the tilting rod 942 drives the horizontal insert 7 to move in a direction away from the horizontal hole 16, thereby realizing the horizontal insert 7 being pulled out from the horizontal hole 16. The pulling out operation of the horizontal insert 7 is synchronized with the pulling out operation of the vertical insert 8, and the smoothness is strong.

[0044] Reference Figure 3 The demoulding mechanism 9 also includes a reset member, which is arranged on the lower template 2 and is used to push the movable plate 91 back to its original position after the demoulding operation is completed, so as to facilitate the next injection molding operation. In this embodiment, the reset member is set as a reset spring 13, which is vertically fixedly connected to the lower template 2, and the upper end of the reset spring 13 is fixedly connected to the lower end of the movable plate 91, and the reset spring 13 is vertically movable and penetrates the lower mold core 4. When the reset spring 13 is in a natural state, the movable plate 91 is in its original position when the demoulding operation is not performed, so as to facilitate the upper template 1 and the lower template 2 to close the mold for injection molding. During the demoulding process of the inner shell of the dust bucket, the movable plate 91 presses the reset spring 13, and the reset spring 13 is compressed. When the demoulding operation is completed, the restoring force of the compressed reset spring 13 pushes the movable plate 91 back to its original position.

[0045] The implementation principle of the dust bucket inner shell molding mold of the embodiment of the present application is as follows: the upper template 1 and the lower template 2 are molded together so that the protrusion 6 and the groove 5 surround a molding cavity to form the dust bucket inner shell, and the injection molding equipment injects the molten plastic into the molding cavity through the injection pipe 18. Under the cooling action of the upper cooling water channel 14 and the lower cooling water channel 15, the molten plastic in the molding cavity is cooled and solidified to obtain the dust bucket inner shell. When demolding operation is required, the upper template 1 and the lower template 2 are separated, and the molded dust bucket inner shell remains on the protrusion 6. The staff presses the driving rod 92 vertically, and the driving rod 92 drives the movable plate 91 to move vertically downward. The vertical push rod 93 supports the dust bucket inner shell, and the protrusion 6 moves with the movable plate 91. The movable plate 91 pushes the upper end of the tilting rod 942 to rotate away from the transverse hole 16, so that the upper end of the tilting rod 942 drives the transverse insert 7 to move away from the transverse hole 16, and the transverse insert 7 is pulled out from the transverse hole 16. The separation of the dust bucket inner shell and the protrusion 6, the extraction of the transverse insert 7 from the transverse hole 16, and the extraction of the vertical insert 8 from the vertical hole 17 can be realized by one driving operation. The operation is simple, the demoulding operation is simplified, the demoulding efficiency is improved, and the product damage is reduced.
