Description

Technical Field

[0001] The utility model relates to a capacitor box mold, in particular to a capacitor box mold convenient for demolding, and belongs to the technical field of mold processing. Background Technique

[0002] A mold is a tool for casting metal parts. The molten metal is first cast into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal. This not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state, and the comprehensive mechanical properties of the blank are significantly improved.

[0003] In a disclosed aluminum alloy die-casting mold convenient for demolding in the Chinese Patent Application Publication Specification CN218460821U, a lead screw is movably connected inside the bottom box. When the device is in use, the staff starts the motor to drive the lead screw to rotate. At this time, the thread block and the connecting plate can move in the direction of approaching each other, driving the two injection templates to fit together, facilitating the injection molding of the device and improving the injection molding efficiency of the device. A clamping plate is fixedly connected to the top of the injection template. When the device is injecting mold, the two injection templates can be closed by rotating the turntable to drive the mounting rod to rotate in the threaded plate, facilitating the injection molding of the device and improving the injection molding efficiency of the device.

[0004] During the use of the above patent, although the thread block and the connecting plate can move in the direction of approaching each other to drive the two injection templates to fit together, facilitating the movement of the injection templates and also facilitating the separation of the injection templates during demolding for easy demolding. However, during the demolding process, although the two injection templates can be separated, the casting may adhere to one of the injection templates, resulting in incomplete demolding. At the same time, although it drives the mounting rod to rotate in the threaded plate by rotating the turntable to close the two injection templates, facilitating the injection molding of the device, during demolding, the high temperature will be transmitted to the position of the mounting rod and the threaded plate, making it inconvenient for the operator to rotate the mounting rod, resulting in a long time required for mold removal and low efficiency. Content of the Utility Model

[0005] The utility model provides a capacitor box mold convenient for demolding, which realizes the rapid demolding of the casting after injection molding and improves the mold removal efficiency during demolding at the same time.

[0006] The utility model is realized by the following technical solutions: A capacitor box mold convenient for demolding includes a base for bearing, a turntable is arranged on the upper surface of the base, the turntable is rotatably connected to the base, injection molding molds are symmetrically arranged on the upper surface of the turntable, the injection molding molds include a left injection template and a right injection template, a limiting device is fixed on the upper surface of the injection molding mold, and injection molding pipes are installed on the upper surfaces of the left injection template and the right injection template.

[0007] The limiting device includes a plug block installed on the upper surface of the left injection mold plate. A slot is fixed on the upper surface of the right injection mold plate. A groove is formed on the upper surface of the plug block. A limiting block is slidably connected to the inner wall of the groove. A corresponding limiting groove is formed on the upper surface of the slot. The limiting block is engaged with the limiting groove. A reset spring is installed on the bottom surface of the limiting block, and the other end of the reset spring is fixed to the plug block. Through the engagement of the limiting block and the limiting groove, the connection between the plug block and the slot is completed.

[0008] A track groove is formed on the upper surface of the turntable. Track blocks are fixed to the bottom surfaces of both the left injection mold plate and the right injection mold plate. The track blocks are slidably connected to the track groove.

[0009] An auxiliary motor is installed on the side of the turntable. A bidirectional threaded rod is installed at the output end of the auxiliary motor. The track block is threadedly connected to the bidirectional threaded rod. By driving the output end of the auxiliary motor, the bidirectional threaded rod can be rotated. By rotating the bidirectional threaded rod, the track block can be driven to move, thereby driving the left injection mold plate and the right injection mold plate to move.

[0010] A plurality of arc-shaped side plates are fixed to the outer surfaces of both the left injection mold plate and the right injection mold plate. Ventilation openings are formed on the sides of the arc-shaped side plates. By driving the rotation of the turntable, the left injection mold plate and the right injection mold plate are driven to rotate. During the rotation of the left injection mold plate and the right injection mold plate, the arc-shaped side plates are driven to rotate. The rotation of the arc-shaped side plates guides air to the outer surfaces of the left injection mold plate and the right injection mold plate and cools them. The ventilation openings allow hot air to flow out of the arc-shaped side plates, preventing the accumulation of hot air.

[0011] A support is fixed to the bottom surface of the base. A forward and reverse motor is installed on the upper surface of the support.

[0012] The track groove formed on the upper surface of the turntable penetrates the entire turntable. An opening is formed on the upper surface of the base. The size of the opening is larger than the size of the track groove and smaller than the size of the turntable. During the demolding process, the generated debris can leave the base through the track groove and the opening, preventing the accumulation of debris and affecting the normal operation of the whole.

[0013] The present utility model provides a capacitor box mold that is convenient for demolding, and its beneficial effects are as follows:

[0014] 1. The capacitor box mold facilitating demolding drives the injection mold to rotate by setting the turntable to rotate. While the rotation of the injection mold makes the injection more uniform, when demolding, the demolding liquid can be injected through the injection tube. The rotation of the turntable maximizes the contact area between the demolding liquid and the casting, thus facilitating the separation of the casting from the injection mold and achieving rapid demolding of the casting after injection molding.

[0015] 2. The capacitor box mold facilitating demolding is provided with inserts and slots. When the left injection template and the right injection template are installed together for injection molding, the insertion of the inserts and slots can maintain the stability of the injection mold. When demolding after injection molding is completed, only by pressing the limit block with any external object can the clamping connection between the limit block and the limit groove be released, thereby realizing the separation of the insert from the slot and achieving rapid mold removal, improving the mold removal efficiency during demolding.

A corresponding limiting groove is formed on the upper surface of the slot 402, and the limiting block 403 is engaged with the limiting groove. A return spring 404 is installed on the bottom surface of the limiting block 403, and the other end of the return spring 404 is fixed to the plug 401. Through the engagement of the limiting block 403 with the limiting groove, the connection between the plug 401 and the slot 402 is completed. A track groove 6 is formed on the upper surface of the turntable 2. Track blocks 7 are fixed on the bottom surfaces of both the left injection template 301 and the right injection template 302, and the track blocks 7 are slidably connected to the track groove 6.

[0028] Please refer specifically to Figure 1 、 Figure 2 and Figure 3 , an auxiliary motor 8 is installed on the side of the turntable 2. A bidirectional threaded rod 9 is installed at the output end of the auxiliary motor 8. The track block 7 is threadedly connected to the bidirectional threaded rod 9. By driving the output end of the auxiliary motor 8, the bidirectional threaded rod 9 can be driven to rotate. By rotating the bidirectional threaded rod 9, the track block 7 can be driven to move, thereby driving the left injection template 301 and the right injection template 302 to move. A plurality of arc-shaped side plates 10 are fixed on the outer surfaces of both the left injection template 301 and the right injection template 302. Ventilation openings 11 are formed on the sides of the arc-shaped side plates 10. By rotating the turntable 2, the left injection template 301 and the right injection template 302 are driven to rotate. During the rotation of the left injection template 301 and the right injection template 302, the arc-shaped side plates 10 are driven to rotate. The rotation of the arc-shaped side plates 10 drives the air to flow to the outer surfaces of the left injection template 301 and the right injection template 302 and cool them. The ventilation openings 11 can allow the hot air to flow out of the arc-shaped side plates 10 to avoid the accumulation of hot air.

[0029] Please refer specifically to Figure 1 、 Figure 2 and Figure 3, a support 12 is fixed to the bottom surface of the base 1, a forward and reverse motor 13 is installed on the upper surface of the support 12, a fixing plate 14 is fixed to the bottom surface of the turntable 2, the output end of the forward and reverse motor 13 is fixed to the fixing plate 14, and the fixing plate 14 can be driven to rotate by the output end of the forward and reverse motor 13, thereby driving the turntable 2 to rotate. The track groove 6 opened on the upper surface of the turntable 2 runs through the entire turntable 2. An opening is opened on the upper surface of the base 1, and the size of the opening is larger than the size of the track groove 6 and smaller than the size of the turntable 2. The debris generated during the demoulding process can leave the base 1 through the track groove 6 and the opening, avoiding debris accumulation and affecting the normal operation of the whole.

[0030] Working principle: When performing injection molding operations, first start the auxiliary motor 8. The output end of the auxiliary motor 8 drives the bidirectional threaded rod 9 to rotate. The rotation of the bidirectional threaded rod 9 drives the track block 7 to move. The track block 7 drives the left injection mold plate 301 and the right injection mold plate 302 to approach each other. Then, an external pouring device injects a solution into the injection mold 3 through the injection mold pipe 5. Start the forward and reverse motor 13, and the output end of the forward and reverse motor 13 drives the turntable 2 to rotate. The rotation of the turntable 2 drives the injection mold 3 to rotate.

[0031] After the injection molding is completed, the output end of the forward and reverse motor 13 reverses. The rotation of the turntable 2 drives the left injection mold plate 301 and the right injection mold plate 302 to rotate. During the rotation of the left injection mold plate 301 and the right injection mold plate 302, the arc-shaped side plate 10 is driven to rotate. The rotation of the arc-shaped side plate 10 guides the air to the outer surfaces of the left injection mold plate 301 and the right injection mold plate 302 and cools them. The ventilation opening 11 allows the hot air to flow out of the arc-shaped side plate 10, avoiding the accumulation of hot air. Then, a demoulding liquid is injected through the injection mold pipe 5, and the forward and reverse motor 13 continues to drive the turntable 2 to rotate. The rotation of the turntable 2 maximizes the contact area between the demoulding liquid and the casting, thereby facilitating the separation of the casting from the injection mold 3 and realizing the rapid demoulding of the casting after the injection molding is completed.

[0032] During injection molding, the insertion of the insertion block 401 and the insertion slot 402 can maintain the stability of the injection mold 3. When demoulding after the injection molding is completed, only by pressing the limit block 403 with any external object can the engagement of the limit block 403 and the limit slot be released, thereby realizing the separation of the insertion block 401 and the insertion slot 402, and then realizing rapid mold removal, improving the mold removal efficiency during demoulding.
