Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, specifically to an auxiliary device for changing the lip mold of a blow molding machine. Background Technology

[0002] A blow molding machine is a specialized piece of equipment that heats, melts, extrudes, or injects plastic raw materials into tubular preforms, then uses compressed air to inflate and cool them to solidify, ultimately producing various hollow plastic containers, such as beverage bottles, oil bottles, and cosmetic bottles. It is the core equipment for producing hollow containers in the plastic packaging industry and is widely used in food, beverage, pharmaceutical, and daily chemical industries. By changing different molds and corresponding parts, it can produce containers of different specifications and shapes to meet diverse needs.

[0003] The lip die replacement auxiliary device for blow molding machines is the end component of the blow nozzle. It is the device that directly contacts the preform to be blown into shape. During the blow molding process, the lip die must first be accurately positioned at the bottle mouth of the plastic preform and clamped by a certain mechanism to ensure that the preform does not shift or shake during the blowing process, thus ensuring the forming accuracy of the bottle mouth. Good lip die design and performance can reduce the scrap rate during the blow molding process, improve production efficiency, and reduce production costs. At the same time, the lip die structure that is easy to replace and maintain also helps to shorten downtime and increase the effective working time of the equipment.

[0004] The prior art patent document CN204451178U provides a blow molding machine lip mold with a replaceable cavity. The cavity of the blow molding machine lip mold is set on the disassembly block. Therefore, when the product specifications change, only the disassembly block needs to be removed and a new disassembly block needs to be replaced. There is no need to remove the connecting block as well, making the operation relatively simple.

[0005] While the existing technology described above ensures the stability of the connection between the disassembly block and the connecting block and guarantees the installation accuracy of the cavity by using the trapezoidal guide rail and dovetail groove of the blow molding machine lip mold, eliminating the need for complex calibration, and the disassembly block can be easily pushed out by simply inserting the ejector pin through the through hole at the bottom of the dovetail groove, resulting in convenient disassembly, high work efficiency, and a simple structure, the lip mold of the blow molding machine in this patented technology requires disassembling the device and then disassembling and replacing the mold when changing the lip mold. This increases working time and reduces work efficiency. Therefore, we need an auxiliary device for changing the lip mold of a blow molding machine. Utility Model Content

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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A lip mold changing auxiliary device for a blow molding machine includes a worktable 1, a fixing block 2 fixedly connected to one side of the worktable 1, a positioning component 3 installed on the top of the worktable 1, and a lifting component 6 provided at the bottom of the worktable 1. The positioning component 3 includes a stepper motor 301. The output end of the stepper motor 301 is detachably connected to a horizontal lead screw 302 via a coupling. A moving block 303 is threadedly connected to the outer wall of the horizontal lead screw 302. A fixed frame 304 is fixedly connected to the top of the moving block 303. A first cylinder 305 is installed on the inner wall of the fixed frame 304. A first clamping ring 306 is provided at one end of the first cylinder 305. A second cylinder 307 is installed on the inner wall of the fixed frame 304. A second clamping ring 308 is provided at one end of the second cylinder 307. The lifting assembly 6 includes a base 601, a hydraulic cylinder 602 is provided on the top of the base 601, and a top plate 603 is connected to the top of the hydraulic cylinder 602. A balance bar 604 is fixedly connected to the top of the base 601, and a sliding ring 605 is slidably connected to the outer wall of the balance bar 604. A support rod 606 is provided on one side of the sliding ring 605.

[0020] Through the above technical solution, the lip mold body 4 is manually placed on the second clamping ring 308, and the first cylinder 305 is activated. The extension and retraction of the first cylinder 305 drives the first clamping ring 306 to move, thereby clamping and fixing the lip mold body 4 from left to right. The extension and retraction of the second cylinder 307 allows the second clamping ring 308 to move upward, thus providing stable support for the lip mold body 4, increasing stability, and allowing for the replacement of lip mold bodies 4 of different specifications at any time. The stepper motor 301 drives the horizontal lead screw 302 to rotate, and the rotation of the horizontal lead screw 302 causes the moving block 303 to move left and right, thereby driving the fixed frame 304 to move left and right. This allows for adjustment of the position of the lip mold body 4. The setting of this component greatly increases the stability of the lip mold body 4, facilitates its adjustment and replacement, saves working time, and improves work efficiency.

[0021] Specifically, the positioning component 3 has a lip mold body 4 installed inside, and the worktable 1 has an equipment door 5 on the front.

[0022] Through the above technical solution, the positioning component 3 can stably install the lip mold body 4, so that it will not shake during operation. The equipment door 5 can open the worktable 1, making it convenient for personnel to disassemble and maintain the stepper motor 301 and the horizontal lead screw 302 installed inside.

[0023] Specifically, the stepper motor 301 forms a moving structure with the horizontal lead screw 302 and the moving block 303, and one end of the horizontal lead screw 302 passes through the moving block 303. The horizontal lead screw 302 forms a moving structure with the fixed frame 304 through the moving block 303.

[0024] Through the above technical solution, the stepper motor 301 drives the horizontal lead screw 302 to rotate. When the horizontal lead screw 302 rotates, the moving block 303 can move left and right. The movement of the moving block 303 can drive the fixed frame 304 to move synchronously, which can adjust the position of the lip mold body 4.

[0025] Specifically, the fixed frame 304 forms a movable structure with the first cylinder 305 and the first clamping ring 306, and the first cylinder 305 is installed between the fixed frame 304 and the first clamping ring 306.

[0026] Through the above technical solution, the extension and retraction of the first cylinder 305 can drive the first clamping ring 306 to move. There are multiple first cylinders 305 and first clamping rings 306, which are respectively installed on both sides of the inner wall of the fixed frame 304. Thus, the movement of the first clamping rings 306 on both sides can clamp and fix the lip mold body 4.

[0027] Specifically, the fixed frame 304 forms a lifting structure with the second cylinder 307 and the second clamping ring 308, and there are two second cylinders 307.

[0028] Through the above technical solution, the extension and retraction of the second cylinder 307 can drive the second clamping ring 308 to rise and fall. The rise of the second clamping ring 308 can play a role in positioning and installing the lip mold body 4, thereby increasing stability.

[0029] Specifically, the base 601 forms a lifting structure with the top plate 603 through hydraulic cylinders 602, and there are two hydraulic cylinders 602.

[0030] Through the above technical solution, the extension and retraction of the hydraulic cylinder 602 can drive the top plate 603 to rise and fall. When the top plate 603 rises, it can simultaneously lift the worktable 1, thus achieving the function of adjusting the height of the worktable 1.

[0031] Specifically, the base 601 forms a sliding structure with the balance bar 604 and the sliding ring 605, and there are multiple balance bars 604. The sliding ring 605 forms a fixed structure with the top plate 603 through the support rod 606.

[0032] Through the above technical solution, the extension and retraction of the hydraulic cylinder 602 can drive the balance bar 604 to move, and the sliding ring 605 can assist the movement of the balance bar 604, enabling it to move stably.

[0033] Working Principle: When using the lip mold changing auxiliary device on this blow molding machine, firstly, the hydraulic cylinder 602 is manually activated. The extension and retraction of the hydraulic cylinder 602 causes the top plate 603 to rise and fall, thus synchronously raising and lowering the worktable 1. Simultaneously with the raising and lowering of the top plate 603, the sliding ring 605 slides synchronously on the balance bar 604 through the connection of the support rod 606, increasing the stability and balance of the top plate 603. After adjusting the height of the worktable 1, the lip mold body 4 is placed on the second clamping ring 308. Then, the first cylinder 305 is activated, and its extension and retraction causes the first clamping ring 306 to move. The two first clamping rings 306 move relative to each other to clamp and fix the lip mold body 4. Then, the second cylinder 307 is activated, which drives the second clamping ring 308 to rise and fall to provide stable support. After the lip mold body 4 is fixed, the stepper motor 301 is activated, which drives the horizontal lead screw 302 to rotate. The rotation of the horizontal lead screw 302 enables the moving block 303 to move left and right, thereby driving the fixed frame 304 to move synchronously. Once the desired position is reached, the work can begin. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
