Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a mold whose flow channel is not easily broken. Background Technology

[0002] In injection molds, runners are typically located on the end face of the slide block. In existing technologies, the runners lack effective fixation after mold opening, making them susceptible to deformation or detachment under external forces during fully automated production. This can trigger abnormal clamping alarms in the part removal machine and cause production stoppages. Furthermore, the fixed push force of the slide block return spring in traditional molds prevents flexible adjustment of the fit between the slide block and the mold cavity according to different injection molding processes (such as material flowability and molding pressure), thus limiting its applicability. Utility Model Content

[0003] The purpose of this invention is to provide a mold with a runner that is not easily broken, which can solve the problems of loosening, deformation, and falling off of the runner in existing injection molds, which leads to production stagnation, as well as the limitations of the sliding block return spring for fixing and the mold's applicability.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1 to 11As shown, a mold with a flow channel that is not easily broken includes an upper mold 1. A flow divider 2 is fixedly connected to the inner wall of the upper mold 1. Flow divider channels 3 are fitted to both the surface of the flow divider 2 and the inner wall of the upper mold 1. A retaining block 4 is fixedly connected to the right side of the flow divider channel 3. An anti-pull groove 5 is formed on the left side of the flow divider 2. The inner wall of the anti-pull groove 5 is fitted to the surface of the retaining block 4. A lower mold 6 is fitted to the bottom of the upper mold 1. A mold core 7 is fixedly connected to the inner wall of the lower mold 6. A slider 8 is slidably connected to the inner wall of the lower mold 6. The upper surface of the slider 8 is fitted to the bottom of the flow divider channel 3. The inner wall of slider 8 is in contact with the surface of the diverter nozzle 2. A groove 9 is provided on the right side of slider 8. A stop block 10 is provided in contact with the inner wall of groove 9. The upper surface of the stop block 10 is fixedly connected to the bottom of the upper mold 1. A circular hole 11 is provided inside slider 8. A guide sleeve 12 is fixedly connected to the inner wall of circular hole 11. A guide post 13 is provided in contact with the inner wall of guide sleeve 12. The left end of guide post 13 is fixedly connected to the inner wall of lower mold 6. A reset spring 14 is sleeved on the surface of guide post 13. An inlet hole 26 is provided inside upper mold 1. The inlet hole 26 is located above the diverter channel 3.

[0031] The guide post 13 has a strip hole 15 inside, and a cylinder 16 is fitted to the inner wall of the strip hole 15. The upper and lower ends of the cylinder 16 are fixedly connected to the inner wall of the guide sleeve 12. A U-shaped plate 25 is fixedly connected to the right side of the lower mold 6, and the inner wall of the U-shaped plate 25 is fixedly connected to the right end of the guide post 13.

[0032] It should be noted that the anti-pull groove 5 and the locking block 4 work together to mechanically engage the flow channel 3 and the flow nozzle 2, thus ensuring that the flow channel 3 remains firmly fixed after the mold opens. When the stop block 10 separates from the groove 9, the return spring 14 allows the slider 8 to separate from the injection-molded workpiece. The guide post 13 and the guide sleeve 12 work together to ensure that the slider 8 can only move left and right. The U-shaped plate 25 can fix the right end of the guide post 13. The cylinder 16 and the strip hole 15 work together to secure the slider 8. When the upper mold 1 and the lower mold 6 are joined together, the slider 8 cannot be separated from the lower mold 6. The bottom slope of the stop block 10 allows the slider 8 to automatically move to the left a certain distance when the stop block 10 just contacts the groove 9 and continues to move downward. After the bottom slope of the stop block 10 separates from the side of the groove 9, the vertical surface on the left side of the stop block 10 prevents the stop block 10 from pushing the slider 8 to the left. When the upper mold 1 and the lower mold 6 are joined together, the flow channel 3 contacts the end face of the slider 8.

[0033] like Figures 1 to 12As shown, a sliding hole 17 is provided on the left side of the lower mold 6. A sliding column 18 is fitted to the inner wall of the sliding hole 17. A ring 19 is fitted on the surface of the guide column 13. The left and right sides of the ring 19 are fitted to the right side of the sliding column 18 and the left side of the return spring 14, respectively. A hollow circular plate 20 is fixedly connected to the left side of the sliding column 18. A bolt 21 is fitted to the inner wall of the hollow circular plate 20. A threaded groove 22 is provided on the left side of the lower mold 6. The inner wall of the threaded groove 22 is threadedly connected to the surface of the bolt 21.

[0034] Among them, a scale 23 is fixedly connected to the left side of the lower mold 6, and an indicator ring 24 is sleeved on the surface of the scale 23. The bottom of the indicator ring 24 is fixedly connected to the upper surface of the hollow circular plate 20.

[0035] It should be noted that, through the cooperation of the sliding hole 17, sliding column 18, ring 19, hollow circular plate 20, bolt 21 and threaded groove 22, the user can change the compression of the return spring 14 by rotating the bolt 21, flexibly adapting to the thrust requirements of the slider 8 for different injection molding processes. At the same time, through the cooperation of the scale 23 and the indicator ring 24, the user can intuitively judge the distance between the hollow circular plate 20 and the lower mold 6.

[0036] The working principle of this utility model is as follows: When the upper mold 1 and the lower mold 6 are closed, the inclined surface at the bottom of the stop block 10 allows the upper mold 1 to push the slider 8 to the left when it moves downward, and makes the flow channel 3 contact the end face of the slider 8. Then, after the upper mold 1 and the lower mold 6 are closed, the raw material is injected into the mold core 7 through the liquid inlet hole 26, the flow channel 3 and the flow nozzle 2, and the raw material is cooled and formed in the mold core 7.

[0037] After the raw material cools and solidifies, the upper mold 1 and the lower mold 6 are separated. At this time, the anti-pull groove 5 and the locking block 4 cooperate to make the flow channel 3 and the flow nozzle 2 mechanically locked together. Thus, the flow channel 3 can still be firmly fixed after the mold is opened. At the same time, when the stop block 10 is separated from the groove 9, the slider 8 can be separated from the injection molded workpiece by the return spring 14.

[0038] When it is necessary to adjust the pushing force of the return spring 14 on the slider 8, the distance between the hollow circular plate 20 and the lower mold 6 can be changed by rotating the bolt 21 under the cooperation of the bolt 21 and the threaded groove 22. At this time, by changing the distance between the hollow circular plate 20 and the lower mold 6, the compression of the return spring 14 can be changed, and the pushing force of the return spring 14 on the slider 8 can be changed.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
