Description
Technical Field
[0001] This utility model relates to the field of blow molding equipment technology, and in particular to a blow molding equipment for producing plastic buckets that are easy to fix. Background Technology
[0002] Blow molding is the main process for producing hollow plastic products, such as plastic buckets, bottles, and cans. Its basic principle is to place the molten tubular plastic preform extruded from an extruder into a mold, then introduce compressed air into the preform to inflate it and make it fit tightly against the inner wall of the mold. After cooling and solidification, the desired hollow product is obtained.
[0003] In traditional blow molding, the molten plastic preform extruded from the extruder waits for the mold to close while suspended vertically. However, because the preform is in a high-temperature molten state, it is soft and easily affected by environmental factors such as gravity and airflow in the workshop, often resulting in shaking, uneven stretching, or deviation from the center line.
[0004] When a misaligned preform is closed, the clamping and compression of the preform by the two halves of the mold becomes uneven, directly leading to uneven wall thickness in the final blow-molded plastic bucket. Areas that are too thin become stress concentration points, significantly reducing the compressive strength and lifespan of the plastic bucket, while areas that are too thick result in material waste. This problem of unstable product quality caused by inaccurate preform positioning is a common defect in existing technologies. Therefore, this invention proposes a blow-molded plastic bucket production equipment that facilitates fixation, to address the shortcomings of existing technologies. Utility Model Content

[0011] Preferably, the protective block is configured to move to the output end of the actuator when the mold is about to close, so as to protect and guide the plastic material.

[0023] 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:
[0024] Reference Figures 1 to 4 This utility model provides a blow molding plastic bucket production equipment that is easy to fix, which aims to solve the problems in the prior art where plastic raw materials are easy to shift before mold closing, and the complex and time-consuming methods of fixing and disassembling the mold 7.
[0025] like Figure 1 and Figure 2 As shown, a blow-molded plastic bucket production equipment for easy fixation includes a support base 1 and a support frame 2 fixedly connected to the support base 1; a motor 3 is fixed to the top of the support frame 2; an electric slide rail 4 is installed on the support base 1; a support plate 6 is slidably connected to the electric slide rail 4, the support plate 6 is used to drive the mold 7 to move in opposite directions, and a protection mechanism 5 is also included. Equipment Reference Figure 2 and Figure 3 The protection mechanism 5 includes a fixed plate 51, a sliding plate 52, a fixed block 53, a protective block 54, and a running component 55; the fixed plate 51 is fixed to the top of the support frame 2; the sliding plate 52 is slidably installed inside the fixed plate 51; the protective block 54 is fixedly connected to the sliding plate 52 through the fixed block 53; the running component 55 is used to link the support plate 6 and the sliding plate 52, so as to drive the protective block 54 to move to the output end of the actuator 3 before the mold 7 is closed. Please refer to Figure 1 and Figure 4 The equipment also includes a replacement mechanism 8 for detachably fixing the mold 7 to the support plate 6; the replacement mechanism 8 includes a fixing block 84 fixed to the outside of the support plate 6, and a stud 85 rotatably mounted on the fixing block 84; the replacement mechanism 8 also includes a sliding plate 81, a telescopic column 82 and a spring 83.
[0026] Reference Figure 2 and Figure 3 The protection mechanism 5 includes a fixed plate 51, a sliding plate 52, a fixed block 53, a protective block 54, and a running component 55; the fixed plate 51 is fixed to the top of the support frame 2, providing an installation base for the sliding plate 52; the sliding plate 52 is slidably installed inside the fixed plate 51; the protective block 54 is fixedly connected to the sliding plate 52 through the fixed block 53, so that the protective block 54 and the sliding plate 52 move synchronously. The running component 55 is used to realize the linkage between the movement of the support plate 6 and the movement of the sliding plate 52. Specifically, the running component 55 includes a limiting block 551 and a control block 552. The control block 552 is fixed to the top of the support plate 6, so the control block 552 moves synchronously with the mold closing movement of the support plate 6. The limiting block 551 is fixed to the bottom of the sliding plate 52. In the assembled state, when the support plate 6 moves, the control block 552 at its top abuts against and drives the limiting block 551 to move when the support plate (6) moves. The limiting block 551 then drives the sliding plate 52, which is fixedly connected to it, to slide inside the fixed plate 51. This linkage structure allows the protective block 54 to move to the output end of the actuator 3 when the mold 7 is about to close, in order to protect and guide the outflowing plastic material.
[0027] Reference Figure 4 The replacement mechanism 8 is used to detachably fix the mold 7 to the support plate 6; the replacement mechanism 8 includes a fixing block 2 84 fixed to the outside of the support plate 6, and a stud 85 rotatably mounted on the fixing block 2 84. The replacement mechanism 8 also includes a second sliding plate 81, which is slidably disposed on the support plate 6 and extends into the interior of the mold 7. The stud 85 is configured to abut against and lock the position of the second sliding plate 81. The replacement mechanism 8 also includes a telescopic column 82, which is fixedly connected to the inner end of the sliding plate 81 and extends into the mold 7 together with the sliding plate 81. The changing mechanism 8 also includes a spring 83, which is housed inside the mold 7 and abuts against the telescopic column 82; Spring 83 is configured to be compressed when slide plate 2 81 slides into mold 7 to unlock mold 7, and to push slide plate 2 81 out in the opposite direction after new mold 7 is installed.
[0028] The implementation principle of this application embodiment is as follows: When the operator uses the blow molding plastic bucket production equipment that is easy to fix, the operator starts the runner 3. The runner 3 is fixed at the top of the support frame 2, and the support base 1 is used to provide installation and fixation for the support frame 2. The runner 3 outputs plastic raw materials. At this time, the electric slide rail 4 runs the support plates 6 on both sides, which drive the mold 7 to move towards each other. When the molds 7 on both sides move to close tightly and the mold is closed, the air blowing device inside the runner 3 introduces high-pressure air into the blank. The high-pressure air inflates the blank, making it completely fit the inner wall of the mold 7. At the same time, the cooling system inside the mold 7 cools the plastic melt and makes it solidify.
[0029] Before the mold 7 closes, the protective mechanism 5 can protect and pre-position the plastic material output by the actuator 3, so that it is aligned with the center of the mold 7. The running component 55 is used to drive the protective mechanism 5 to run. The specific method is as follows: when the support plate 6 moves, it will drive the control block 552 fixed at the top of the support plate 6 to move synchronously, which in turn drives the limit block 551 fixed at the bottom of the sliding plate 52 to move, which in turn drives the sliding plate 52 to slide inside the fixed plate 51 fixed at the top of the support frame 2. When the mold 7 is about to close, the protective block 54 can protect the output end of the actuator 3 to prevent the plastic material from flowing out of the equipment, and at the same time guide the flowing plastic material. The fixed block 53 is used to connect the protective block 54 and the sliding plate 52 to make them a whole.
[0030] When processing plastic buckets of different specifications, the mold 7 can be quickly replaced by the replacement mechanism 8. The specific method is as follows: rotate the stud 85 to remove the fixation of the second fixing block 84 and the second sliding plate 81. The second fixing block 84 is fixed to the outside of the support plate 6. Press the second sliding plate 81 to make it slide into the inside of the mold 7, thereby making the telescopic column 82 slide into the inside of the mold 7 and compress the spring 83. Take out the mold 7 and slide the mold 7 to be replaced into the inside of the support plate 6. At this time, the compressed spring 83 pushes the second sliding plate 81 out of the outside of the support plate 6 in the opposite direction. Rotate the stud 85 in the opposite direction to fix the position of the second fixing block 84, thereby fixing the position of the mold 7 in the support plate 6.

Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
