Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and in particular to a pre-embedded insert mold for a double-station vertical injection molding machine. Background Art

[0002] An injection mold is a tool used to produce plastic products. It consists of a movable mold and a fixed mold. A cavity is left between the movable mold and the fixed mold for cooling and fixing the product.

[0003] The injection molding machine injects the heated molten plastic raw material into the cavity of the injection mold through the pressure of the screw. After the plastic raw material cools and solidifies, it opens the mold by separating the fixed mold and the movable mold to take out the finished product.

[0004] In related technology, a dual-station vertical injection molding machine includes two sets of injection molds and a turntable. The two sets of injection molds are placed opposite each other on the turntable. An injection molding device is installed above the turntable, and the bottom of the turntable is driven by a motor. When one set of injection molds is completed, the motor drives the turntable to rotate the injection mold, allowing the other set of molds to be quickly replaced for injection, thereby improving the operating efficiency of the injection molding machine.

[0005] With respect to the above-mentioned related technologies, the inventors found that the turntable is only driven by a motor to perform the position change of the injection mold. The position change of the turntable is not precise enough and easily affects the normal operation of the injection mold, so it needs to be improved. Summary of the Invention

[0006] In order to improve the problem of inaccurate position change of injection molds, the present application provides a pre-embedded insert mold for a double-station vertical injection molding machine.

[0007] The present application provides a double-station vertical injection molding machine embedded insert mold adopts the following technical solution:

[0008] A pre-embedded insert mold for a double-station vertical injection molding machine includes a rotating disk and two groups of mold groups arranged on the upper surface of the rotating disk; a mounting platform for supporting the rotating disk is provided on the side wall of the rotating disk away from the mold group, and a driving component for driving the rotating disk to rotate is provided on the mounting platform; a trigger block is provided on the side wall of the rotating disk facing the mounting platform, and a sliding track for moving the trigger block is provided on the side wall of the mounting platform; a control button for controlling the power off of the driving component is provided inside the sliding track, a telescopic component for driving the control button to enter or exit the sliding track is provided on the mounting platform, and a buffer component for mitigating the impact force of the trigger block is provided on the telescopic component.

[0009] By adopting the above technical solution, the driving component drives the rotating disk to rotate, thereby driving the mold group to shift and driving the trigger block to move inside the sliding track; the telescopic component drives the control button to move into the sliding track, and the trigger block contacts the control button during the movement to control the driving component to cut off power, thereby stopping the rotating disk from rotating, achieving precise pause of the rotating disk and improving the shifting accuracy of the mold group; the buffer component effectively reduces the damage to the control button caused by the impact force of the trigger block; when it is necessary to continue shifting, the telescopic component is controlled to make the control button disengage from the sliding track, so that the rotating disk and the trigger block can continue to rotate.

[0010] Preferably, the driving assembly includes a driving motor, a driving gear, a linkage block and a transmission gear ring; the side wall of the mounting platform is provided with a mounting groove for the driving motor to be inserted into, the power on and off of the driving motor is controlled by a control button, and the driving gear is arranged at the output end of the driving motor; the linkage block is arranged on the side wall of the rotating disk facing the mounting platform, and the linkage block is rotatably connected to the inner side wall of the mounting groove; the transmission gear ring is arranged on the linkage block, and the transmission gear ring is engaged with the driving gear.

[0011] By adopting the above technical solution, the output end of the driving motor drives the driving gear to rotate, and the driving gear engages with the toothed ring to drive the rotating disk to rotate; when the driving motor is powered off, the driving gear stops rotating, and the driving gear and the toothed ring offset each other through meshing, which can achieve rapid braking of the rotating disk and reduce the occurrence of the trigger block being reversed due to the buffer component.

[0012] Preferably, the telescopic assembly includes a telescopic cylinder and a moving block; the telescopic cylinder is arranged on the mounting table, the moving block is arranged at the output end of the telescopic cylinder, and the inner side wall of the sliding track is provided with an abutment groove for the moving block to abut against; the control button is arranged on the moving block, and the buffer assembly is arranged on the moving block.

[0013] By adopting the above technical solution, the output end of the telescopic cylinder extends, so that the moving block abuts against the inside of the abutment groove to move the control button and the buffer assembly into the sliding track; in addition, the moving block abuts against the inner side wall of the abutment groove, reducing the phenomenon of the moving block shaking caused by the abutment between the trigger rod and the moving block; when the output end of the telescopic cylinder contracts, the moving block drives the control button and the buffer assembly to quickly leave the sliding track.

[0014] Preferably, a guide block is provided on the side wall of the moving block facing the mounting platform, a sliding groove for the guide block to slide is provided on the inner side wall of the sliding track, and a guide rod for passing through the guide block is provided inside the sliding groove.

[0015] By adopting the above technical solution, during the movement of the moving block, the guide block and the guide rod are abutted to guide and limit the movement of the moving block, reducing the offset phenomenon during the movement of the moving block, thereby improving the movement accuracy of the moving block.

[0016] Preferably, the buffer assembly includes a trigger rod, a buffer spring and a contact plate; an installation cavity is opened inside the moving block, the control button is arranged inside the installation cavity, and the trigger rod is slid through the moving block to contact the control button; the contact plate is arranged at the end of the trigger rod away from the control button, the buffer spring is sleeved on the trigger rod, one end of the buffer spring is against the side wall of the moving block, and the other end of the buffer spring is against the contact plate.

[0017] By adopting the above technical solution, the trigger block and the contact plate are in contact with each other, pushing the trigger rod to move toward the direction close to the control button, so that the buffer spring deforms and contracts, converting the kinetic energy of the trigger block into elastic potential energy, thereby playing a buffering role; the contact plate drives the trigger rod to gradually approach the control button, and the trigger rod contacts the trigger point of the control button to control the power on and off of the drive component.

[0018] Preferably, an anti-slip plate is provided at the end of the trigger rod facing the control button, and a limiting rod for penetrating the anti-slip plate is provided on the inner side wall of the installation cavity.

[0019] By adopting the above technical solution, the anti-slip plate reduces the occurrence of the buffer spring driving the trigger rod out of the installation cavity; the anti-slip plate increases the contact area between the trigger rod and the control button, so as to stably resist the trigger point of the control button; in addition, the limit rod limits the movement path of the anti-slip plate, so that the anti-slip plate can more stably resist the control button.

[0020] Preferably, a brake spring is provided inside the installation cavity, one end of the brake spring abuts against the inner wall of the installation cavity, the other end of the brake spring abuts against the anti-slip plate, and the limiting rod passes through the brake spring.

[0021] By adopting the above technical solution, when the anti-slip plate moves toward the control button, the anti-slip plate and the brake spring are offset, causing the brake spring to deform and contract, further converting the kinetic energy of the trigger block into elastic potential energy, thereby playing a buffering role.

[0022] Preferably, the mounting platform is provided with a plurality of groups of balls rotatably disposed on the side wall of the rotating disk, and each of the balls abuts against the rotating disk.

[0023] By adopting the above technical solution, the ball bearings reduce the friction resistance between the rotating disk and the mounting platform, so that the rotating disk can rotate faster.

[0024] Preferably, a limiting component for reducing the reversal of the trigger block is provided on the mounting platform.

[0025] By adopting the above technical solution, the limiting component prompts the trigger block to brake, reducing the reversal phenomenon after the trigger block collides with the buffer component or the control button, and further improving the accuracy of the rotating disk replacement.

[0026] Preferably, the limiting assembly includes a limiting cylinder and an insertion rod; the limiting cylinder is arranged on the mounting table, the insertion rod is arranged at the output end of the limiting cylinder, and a passage hole for the insertion rod to pass through is opened on the trigger block.

[0027] By adopting the above technical solution, the output end of the limit cylinder extends out, so that the insertion rod is pressed into the inside of the passage hole, thereby realizing rapid braking of the trigger block.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting up a telescopic component to drive the control button to move into the sliding track, the trigger block contacts the control button during movement, thereby controlling the drive component to cut off power, thereby stopping the rotation of the rotating disk. This achieves a precise pause of the rotating disk and improves the position change accuracy of the mold assembly. The buffer component effectively reduces the damage to the control button caused by the impact force of the trigger block.

[0030] 2. By setting the trigger block against the contact plate, the trigger rod is pushed toward the control button, causing the buffer spring to deform and contract, converting the kinetic energy of the trigger block into elastic potential energy, thus playing a buffering role;

[0031] 3. By setting a limit assembly to prompt the trigger block to brake, the reversal phenomenon after the trigger block collides with the buffer assembly or the control button is reduced, and the accuracy of the rotating disk transposition is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] The embodiment of the present application discloses a pre-embedded insert mold for a double-station vertical injection molding machine, which is used to improve the accuracy of mold replacement.

[0041] Reference Figure 1 and Figure 2 A pre-embedded insert mold for a double-station vertical injection molding machine includes a rotating disk 1 and two sets of mold assemblies 11 fixedly mounted on the upper surface of the rotating disk 1.

[0042] Reference Figure 2 and Figure 3 The drive motor 31 is fixedly connected to the inner side wall of the mounting groove 22, and the drive gear 32 is fixedly mounted on the output end of the drive motor 31. The transmission gear is fixedly mounted on the side wall of the linkage block 33 facing the drive motor 31, and the transmission gear ring 34 is meshed with the drive gear 32, so that when the output end of the drive motor 31 rotates, the rotating disk 1 can be driven to rotate.

[0043] Reference Figure 2 and Figure 3The mounting platform 2 is rotated toward the side wall of the rotating disk 1 and is embedded with several groups of balls 26, and each group of balls 26 abuts against the bottom wall of the rotating disk 1, thereby reducing the friction resistance between the rotating disk 1 and the mounting platform 2.

[0044] Reference Figure 3 and Figure 4 A trigger block 12 is fixedly mounted on the side wall of the rotating disk 1 facing the mounting platform 2. In this embodiment, there are two sets of trigger blocks 12, and the two sets of trigger blocks 12 are symmetrically distributed about the central axis of the rotating disk 1. A sliding track 21 is provided on the side wall of the mounting platform 2 facing the rotating disk 1, allowing the two sets of trigger blocks 12 to slide against each other. A control button 20 is mounted within the sliding track 21. In this embodiment, the control button 20 is electrically connected to the drive motor 31. The drive motor 31 is deenergized by contacting the trigger point of the control button 20.

[0045] Reference Figure 3 and Figure 4 The inner wall of the sliding track 21 is provided with a receiving groove 23, inside which a telescopic assembly 4 is installed for driving the control button 20 into or out of the sliding track 21. The telescopic assembly 4 includes a telescopic cylinder 41 and a moving block 42. The telescopic cylinder 41 is fixedly connected to the receiving groove 23, and the moving block 42 is fixedly installed at the output end of the telescopic cylinder 41 and can move in response to the extension and contraction of the output end of the telescopic cylinder 41.

[0046] Reference Figure 3 and Figure 5 The inner sidewall of the sliding track 21 facing the mounting groove 23 defines an abutment groove 24 for the end of the moving block 42, which is away from the telescopic cylinder 41, to abut against. A guide block 422 is fixedly connected to the sidewall of the moving block 42 facing the mounting platform 2. A sliding groove 25 is defined on the inner sidewall of the sliding track 21 for the guide block 422 to slide into. A guide rod 251 is fixedly connected to the interior of the sliding groove 25 along its length, and the guide rod 251 extends through the guide block 422.

[0047] Reference Figure 3 and Figure 4 A mounting cavity 421 is provided inside the moving block 42, and the control button 20 is located on the inner wall of the mounting cavity 421; a buffer assembly 5 is installed on the moving block 42 to reduce the impact force of the trigger block 12 and transfer the force to the control button 20.

[0048] Reference Figure 3 and Figure 4The buffer assembly 5 includes a trigger rod 51, a buffer spring 52, and a contact plate 53. The trigger rod 51 slides and inserts onto the moving block 42, with one end of the trigger rod 51 located within the mounting cavity 421 for contacting the control button 20. The contact plate 53 is fixedly connected to the end of the trigger rod 51 away from the control button 20. The buffer spring 52 is sleeved on the trigger rod 51, with one end of the buffer spring 52 adhesively connected to the outer wall of the moving block 42, and the other end of the buffer spring 52 adhesively connected to the contact plate 53.

[0049] Reference Figure 3 and Figure 4 One end of the trigger rod 51 located within the mounting cavity 421 is glued to an anti-slip plate 511. Several sets of limiting rods 423 are fixedly connected to the mounting cavity 421. The lengths of all limiting rods 423 are parallel to the length of the trigger rod 51 and all of them pass through the anti-slip plate 511. A brake spring 424 is sleeved on each set of limiting rods 423. One end of the brake spring 424 is glued to the inner wall of the mounting cavity 421, and the other end of the brake spring 424 is glued to the anti-slip plate 511.

[0050] Reference Figure 3 and Figure 4 A limit assembly 6 is mounted on the mounting platform 2. The limit assembly 6 includes a limit cylinder 61 and a penetration rod 62. The limit cylinder 61 is fixedly connected to the mounting platform 2, and the penetration rod 62 is fixedly connected to the output end of the limit cylinder 61. A passage hole 121 is formed through the side wall of the trigger block 12 to allow the penetration rod 62 to pass through. The penetration rod 62 abuts against the inner side wall of the passage hole 121, thereby limiting the position of the trigger block 12 and preventing the trigger block 12 from being reversed after contacting the buffer assembly 5.

[0051] The implementation principle of a double-station vertical injection molding machine pre-embedded insert mold in the embodiment of the present application is as follows:

[0052] The driving motor 31 is started, and the output end of the driving motor 31 drives the driving gear 32 to rotate. The driving gear 32 engages with the toothed ring for transmission, and the rotating disk 1 drives the trigger block 12 and the mold assembly 11 to rotate and shift through the linkage block 33.

[0053] The output end of the telescopic cylinder 41 is controlled to extend, forcing the moving block 42 into the interior of the sliding track 21. One set of trigger blocks 12 gradually approaches the moving block 42, where they abut against the contact plate 53, exerting pressure on the buffer spring 52, causing it to deform and contract. The contact plate 53 causes the trigger rod 51 to drive the anti-slip plate 511 gradually toward the control button 20. The brake spring 424, under pressure from the anti-slip plate 511, gradually deforms and contracts, converting the kinetic energy of the trigger block 12 into elastic potential energy, reducing the impact force between the trigger block 12 and the moving block 42.

[0054] Finally, the anti-slip plate 511 contacts the trigger point of the control button 20 to control the power off of the driving motor 31, thereby accurately controlling the position of the rotating disk 1 to rotate and change position, thereby improving the accuracy of the mold assembly 11 change position.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
