Description

Technical Field

[0001] This utility model relates to the field of mold release agent spraying technology, and more specifically, to a liquid supply adjustment mechanism for mold release agent spraying. Background Art

[0002] Release agent is a functional substance that lies between the mold and the finished product. It is chemically resistant, adhering to the mold without transferring to the processed part, thus preventing interference with painting or other secondary processing operations. When processing parts of the same shape but different specifications, the required release agent volume varies depending on the part's size. Therefore, the release agent spraying volume needs to be adjusted to avoid waste. Existing adjustment methods typically involve manual back-and-forth movement between the delivery terminal and the spraying process to achieve the desired level. This adjustment process is cumbersome and may affect other processes. Therefore, we propose a release agent spraying volume adjustment mechanism. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a release agent spraying liquid adjustment mechanism to solve the technical problem that the release agent liquid adjustment is relatively troublesome when processing parts of different specifications.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a liquid supply adjustment mechanism for spraying release agent, including a spray shell, an extension port installed on the top of the spray shell, a conveying channel connected to the top of the extension port, a liquid inlet pipe connected to one side of the conveying channel, a flow plug with a conical structure below the conveying channel, an adjustment structure at the bottom of the flow plug, a control structure at the center of the adjustment structure, a differential structure located inside the spray shell below the control structure, and a lifting structure inside the differential structure.

[0005] Preferably, the spray shell includes a top cover and a bottom plate, with multiple spray nozzles installed on the bottom of the bottom plate, and an outer protective plate and an inner sleeve plate that are interlocked between the bottom plate and the top cover.

[0006] Preferably, the adjustment structure includes two L-shaped bodies connected to the extension port, each L-shaped body having a protruding plate at its bottom, a first bearing being disposed between the inner circumferences of the two protruding plates, and an adjustment screw being connected to the inner ring of the first bearing.

[0007] Preferably, the outer circumference of the adjusting screw is threaded with an adjusting screw tube connected to the flow plug, and one end of the L-body is integrally formed with a sliding seat that slides and limits the adjusting screw tube.

[0008] Preferably, the control structure includes a rotary rod, a first locking block, and a second locking block. The rotary rod passes through the conveying channel and the flow plug and is located at the center of the spray shell. The bottom of the adjusting screw has a first locking groove that matches the first locking block.

[0009] Preferably, the differential structure includes multiple partition plates with proportionally increasing sizes and a partition sleeve plate sleeved around the periphery of the partition plates. The partition plates and the partition sleeve plate are respectively connected to each other. The partition plates have liquid inlets, and the partition sleeve plates have misalignment openings. The misalignment openings on the multiple different partition sleeve plates are evenly distributed at different horizontal positions.

[0010] Preferably, the lifting structure includes a lifting sleeve fixed to the base plate, a lifting screw threadedly connected to the inner circumference of the lifting sleeve, a second slot adapted to the second locking block being provided at the top of the lifting screw, a second bearing being provided on the outer circumference of the lifting screw, and a connecting plate being fixed between the outer ring of the second bearing and one side of the adjacent dividing sleeve plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This utility model, through the design of the conical structure of the flow plug and the threaded connection between the conical structure and the adjusting screw and adjusting tube, and through the L-frame, the first bearing to fix the position of the adjusting screw, and the anti-rotation limiting structure of the sliding seat and adjusting tube, allows the gap between the flow plug and the conveying channel to be adjusted by directly rotating the rotating rod during the spraying process, which drives the first locking block to rotate. This achieves the effect of convenient flow adjustment and solves the problem of troublesome adjustment of the release agent supply when processing parts of different specifications.

[0013] 2. This utility model further divides the spraying area into different spaces through the partition plate and partition sleeve plate, which can adapt to the processing of parts of different specifications. Then, through the cooperation of the second locking block and the second locking groove, and the threaded connection of the lifting screw sleeve and the lifting screw, combined with the spacing design of the liquid inlet and the misalignment port, the spraying area can be adjusted by rotating the pressing screw when the second locking block and the second locking groove are engaged. In addition, with the above-mentioned flow rate adjustment, it can be adapted to parts of different specifications, further solving the problem that the spraying area cannot be adapted after the liquid supply flow rate is adjusted when processing parts of different specifications.

[0027] like Figures 1 to 7 As shown, the present invention relates to a release agent spraying liquid supply adjustment mechanism, including a spraying shell 1. The spraying shell 1 is composed of a top cover 101, a bottom plate 102, an outer protective plate 104, an inner sleeve plate 105, and multiple spray nozzles 103. The multiple spray nozzles 103 are installed at the bottom of the bottom plate 102. The outer protective plate 104 is connected to the top cover 101. The bottom of the inner sleeve plate 105 is connected to the top of the bottom plate 102. The outer protective plate 104 and the inner sleeve plate 105 are nested together. An extension port 2 is installed at the top of the top cover 101. A conveying channel 3 is connected to the top of the extension port 2. A liquid inlet pipe 4 is connected to one side of the conveying channel 3. The liquid inlet pipe 4 is connected to an external release agent supply pipe. A flow plug 5 with a conical structure is provided below the conveying channel 3.

[0028] In an embodiment of this utility model, in order to adjust the liquid supply flow rate, the flow plug 5 is provided with an adjustment structure 6 at the bottom. The adjustment structure 6 includes two L-shaped bodies 601 connected to the extension port 2. The bottom of each L-shaped body 601 is provided with a protruding plate 602. A first bearing 603 is provided between the inner circumferences of the two protruding plates 602. An adjustment screw 604 is connected to the inner ring of the first bearing 603. An adjustment screw tube 605 connected to the flow plug 5 is threaded on the outer circumference of the adjustment screw 604. One end of the L-shaped body 601 is integrally formed with a sliding seat 606 that limits and slides with the adjustment screw tube 605. A groove adapted to the sliding seat 606 is opened on the outer circumference of the adjustment screw tube 605.

[0029] To drive the adjusting screw 604, a first slot is provided at the bottom of the adjusting screw 604. A control structure 7 is provided at the center of the adjusting structure 6. The control structure 7 includes a rotating rod 701, a first locking block 702, and a second locking block 703. The rotating rod 701 passes through the conveying channel 3 and the flow plug 5 and is located at the center of the spray shell 1. It should be noted that the part of the rotating rod 701 that passes through the conveying channel 3 is sealed by sealing components such as rubber gaskets. The first locking block 702 can be engaged into the first slot. A rotating head 10 is connected to the top of the rotating rod 701. By rotating the rotating head 10, the rotating rod 701 can be driven to rotate, causing the adjusting screw 604 to rotate, causing the adjusting screw tube 605 to rotate, further changing the position of the flow plug 5, changing the gap between the flow plug 5 and the conveying channel 3, and thus changing the flow rate.

[0030] Furthermore, a cylindrical sleeve 11 fixed to the conveying channel 3 is provided below the rotating head 10. An annular plate 12 fixed to the rotating rod 701 is provided on the inner circumference of the cylindrical sleeve 11. A spring 13 is provided below the annular plate 12. The elastic restoring force of the spring 13 ensures that the first locking block 702 is always engaged with the first locking groove.

[0031] In an embodiment of this utility model, in order to further adapt to the processing of parts of different specifications, a differential structure 8 is provided below the control structure 7 and is located inside the spray shell 1. The differential structure 8 includes multiple partition plates 801 with proportionally increasing sizes and partition sleeve plates 802 sleeved on the outer periphery of the partition plates 801. The partition plates 801 and partition sleeve plates 802 are respectively connected to the partition plates 801. The partition plates 801 are provided with liquid inlets 803 and the partition sleeve plates 802 are provided with misalignment ports 804. The misalignment ports 804 on multiple different partition sleeve plates 802 are distributed at equal intervals at different horizontal positions. By adjusting the position of the liquid inlets 803, the liquid inlets 803 are connected to different misalignment ports 804, so that the connection between different areas can be achieved.

[0032] To achieve the driving function, the differential structure 8 is equipped with a lifting structure 9. The lifting structure 9 includes a lifting sleeve 901 fixed to the base plate 102. The inner circumference of the lifting sleeve 901 is threaded with a lifting screw 902. The top of the lifting screw 902 is provided with a second slot. The outer circumference of the lifting screw 902 is provided with a second bearing 903. The outer ring of the second bearing 903 is fixed with a connecting plate 904 between it and one side of the adjacent partition plate 802. The second locking block 703 can be inserted into the second slot and engaged. After engagement, rotating the second locking block 703 causes the lifting screw 902 to rotate, thereby raising and lowering the lifting sleeve 901. This further realizes the change of the distance between the partition plate 801 and the partition plate 802, and the adjustment of the spraying area at different times.

[0033] Working principle: This embodiment provides a liquid supply adjustment mechanism for mold release agent spraying. When in use, according to the specifications and dimensions of the processed parts, rotating the rotating head 10 can drive the rotating rod 701 to rotate, causing the adjusting screw 604 to rotate, causing the adjusting screw tube 605 to rotate, further changing the position of the flow plug 5, changing the gap between the flow plug 5 and the conveying channel 3, and changing the flow rate to an appropriate state.

[0034] Press the rotary rod 701 again to separate the first locking block 702 from the first locking slot, and simultaneously engage the second locking block 703 with the second locking slot. Then rotate the rotary rod 701 to rotate the lifting screw 902 (at this time, because the first locking block 702 is separated from the first locking slot, the adjusting screw 604 will not rotate), causing the lifting sleeve 901 to rise and fall, further changing the distance between the partition plate 801 and the partition sleeve plate 802 (e.g., Figure 6 This allows it to be adapted to process parts of different specifications.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
