Description

Technical Field

[0001] This utility model relates to the field of bottom mold fixture technology, specifically to a multi-purpose lifting platform bottom mold fixture. Background Technology

[0002] A bottom mold fixture is an auxiliary tool that plays a role in positioning, fixing, and guiding during the production process, helping to improve production accuracy and efficiency. Currently, bottom mold fixtures are frequently used in toy manufacturing, effectively securing the toy and facilitating subsequent operations. They are also commonly used in industries such as marking and pad printing. For example, when marking small, complex-shaped items, the bottom mold fixture helps to fix the item in place, making the marking process more stable. Similarly, in pad printing, the bottom mold fixture is a crucial auxiliary tool, accurately fixing the item to be printed on the pad printing machine's worktable, allowing the printing head to precisely transfer patterns or text onto the item's surface.

[0003] Regarding bottom mold fixtures, application publication number CN103240630A discloses a milling machine fixture for machining the end face of a small wine bottle mold blank. It includes a base detachably connected to the milling machine for placing the wine bottle mold blank, a hydraulic cylinder fixed to the base, a clamping part that presses against one side of the wine bottle mold blank when fixing it, and an abutting part fixed to the base for pressing against the other side of the wine bottle mold blank. One end of the clamping part is connected to the upper end of the piston rod of the hydraulic cylinder, and its other end is located on the wine bottle. Above the mold blank, the bottle mold blank is semi-cylindrical, with its chordal plane tightly against the upper surface of the base. The clamping part and the abutting part abut against the arc-shaped side surface of the bottle mold blank, thereby fixing the bottle mold blank to the base. The clamping part includes a support rod with one end perpendicularly connected to the upper end of the piston rod and a pressure block connected to the other end of the support rod. The pressure block has a downward-sloping arc-shaped clamping surface, which abuts against the arc-shaped side surface of the bottle mold blank. The abutting part includes a support platform fixedly connected to the base and multiple bolts threadedly connected to the support platform. The axes of all the bolts are parallel to the horizontal plane and perpendicular to the axis of the bottle mold blank. The stud of each bolt is threadedly connected to the support platform, and the bolt head is tightened against the bottle mold blank.

[0004] However, the milling machine fixture mentioned above for processing the end face of small wine bottle mold blanks still has some drawbacks. For example, since it fixes the blank by using a pressure block and bolts in conjunction with the base, if you want to position workpieces of different thicknesses, you often need to replace the pressure block and the abutment with different sizes. Otherwise, the positioning of the workpiece will be unstable due to size issues. In other words, the fixture mentioned above cannot position workpieces of different thicknesses without changing parts, and its applicability is not good enough. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a multi-purpose lifting platform bottom mold fixture, which can be used for positioning workpieces of different thicknesses without changing the parts.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A multi-purpose lifting platform bottom mold fixture includes a housing with an upper opening for mounting cavities, multiple support components evenly installed in the mounting cavities and having rocking and telescopic properties, a positioning baffle frame movable up and down in the mounting cavities, a position adjustment mechanism disposed on the housing for adjusting the positioning baffle frame up and down, and a positioning mechanism disposed on the housing for sequentially pressing or releasing the multiple support components against each other. During installation, the support components at corresponding positions can be compressed and retracted according to the shape of the workpiece. The positioning baffle frame can be used to abut against the bottom surface of the workpiece and position its height. Furthermore, by cooperating with the position adjustment mechanism to adjust the position of the positioning baffle frame, workpieces of different thicknesses can be positioned.

[0008] Furthermore, the position adjustment mechanism includes two adjustment components respectively disposed on both sides of the housing; each adjustment component includes a connecting slide plate, an adjusting bolt, and a mounting block; the two connecting slide plates of the two adjustment components are respectively located on the two outer surfaces of the housing and their upper ends are respectively connected to the two sides of the positioning frame, and each connecting slide plate is provided with a vertically extending strip-shaped sliding hole; one end of each mounting block is correspondingly inserted into one of the strip-shaped sliding holes and fixed to the housing, and the other end of each mounting block is provided with a first threaded hole that penetrates both internally and externally; the shank of each adjusting bolt is correspondingly threaded into one of the first threaded holes and abuts against the outer surface of the connecting slide plate. Through the above arrangement, the connecting slide plate can be loosened or locked by moving the adjusting bolt inward or outward.

[0009] Furthermore, each of the adjustment components also includes a scale; each scale extends vertically and is mounted on the outer surface of the housing and located on the corresponding side of the connecting slide plate; each connecting slide plate is provided with an indicator mark for pointing to the scale mark. By setting up mutually cooperating scale marks and indicators, operators can more accurately adjust the position of the connecting slide plate and avoid position adjustment errors.

[0010] Furthermore, the mounting block is locked and fixed to the outer casing by bolts.

[0011] Furthermore, each of the support components includes a top post and an elastic element mounted on the top post; the first end of the top post extends upward into the mounting cavity; the elastic element includes a spring mounted in the insertion cavity of the top post and an abutment rod whose first end is movably engaged in the insertion cavity and whose second end is fixed in the mounting cavity, the spring being used to provide telescopic elastic force for the top post; the top post is movable up and down, and the top post and the abutment rod are in clearance fit. This configuration facilitates the telescopic and swaying movements of the top post.

[0012] Furthermore, the positioning mechanism includes a push plate and a knob; a mounting hole extending through to the mounting cavity is provided on the side of the housing; the push plate is fitted into the mounting hole and its first end face abuts against the side of the top post of each of the support components located at the edge; a limiting plate covering the push plate is also provided on the side of the housing, and a second threaded hole corresponding to the push plate is provided on the limiting plate; the knob's rod is threaded from the outside to the inside into the second threaded hole and passes through the second threaded hole to abut against the second end face of the push plate. This configuration facilitates the movement of the push plate.

[0013] Furthermore, the outer end face of the top post is planar with an arc-shaped transition around it, which can prevent scratching the workpiece.

[0014] Furthermore, the positioning frame includes a rectangular frame-shaped retaining edge and retaining strips connected at both ends to the middle of the two sides of the retaining edge. This configuration allows the top of the retaining strips to provide primary support for the workpiece, while the retaining edge can support the edges of larger workpieces, thereby improving stability.

[0015] Furthermore, it also includes a partition plate, a first connector, and a second connector; the partition plate is disposed in the mounting cavity and divides the mounting cavity into a first mounting cavity and a second mounting cavity; multiple support components are matchedly disposed in both the first mounting cavity and the second mounting cavity; the first connector and the second connector are respectively mounted on the outer shell; the first connector communicates with the first mounting cavity, and the second connector communicates with the second mounting cavity. This configuration facilitates dust removal or cooling operations on the first and second mounting cavities.

[0016] Furthermore, the multiple support components in the first mounting cavity and the second mounting cavity are arranged in multiple rows to ensure support force.

[0017] The beneficial effects of this utility model are as follows:

[0018] Because this invention has multiple support components, the workpiece can be directly embedded in the corresponding support component and the support component can be compressed to complete the initial positioning. Then, a positioning baffle is used to prevent the workpiece from falling, which ensures the positional stability of the workpiece and limits the height of the workpiece.

[0019] Specifically, the position adjustment mechanism can be used to adjust the vertical height of the positioning frame. In addition, after adjusting the positioning frame to different heights, different height restrictions can be formed on the workpiece, so that the bottom mold fixture can be used for positioning workpieces of different thicknesses without changing the parts. For example, for thicker workpieces, the positioning frame can be lowered, while for thinner workpieces, the positioning frame can be raised. The positioning frame can prevent the workpiece from being embedded too deeply in the support component, which is not conducive to processing.

[0020] At the same time, the positioning mechanism can make each support component press against and position itself in sequence. After the positioning mechanism is in position, the workpiece can no longer be pushed down to retract the support components, thus fixing the workpiece and making it less likely to loosen during processing, ensuring the processing effect.

[0039] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0040] like Figures 1-7As shown, a multi-purpose lifting platform bottom mold fixture includes a housing 1 with an upper opening for the mounting cavity, multiple support components 2 evenly installed in the mounting cavity and having rocking and telescopic properties, a positioning baffle 3 movable up and down in the mounting cavity, a position adjustment mechanism 4 disposed on the housing 1 for adjusting the positioning baffle 3 up and down, and a positioning mechanism 5 disposed on the housing 1 for sequentially pressing or releasing the multiple support components 2 against each other. During installation, the support components 2 at corresponding positions can be compressed and retracted according to the shape of the workpiece. The positioning baffle 3 can be used to abut against the bottom surface of the workpiece and position the height of the workpiece. By adjusting the position of the positioning baffle 3 through the position adjustment mechanism 4, workpieces of different thicknesses can be positioned to meet the needs of different workpieces.

[0041] In summary, this utility model, by incorporating multiple support components 2, allows the workpiece to be directly embedded in the corresponding support component 2 and compressed to achieve initial positioning. Then, a positioning baffle 3 is used to prevent the workpiece from descending, ensuring its positional stability and limiting its height. The position adjustment mechanism 4 can adjust the vertical height of the positioning baffle 3. Furthermore, by adjusting the positioning baffle 3 to different heights, different height restrictions can be imposed on the workpiece, allowing the bottom mold fixture to be used for processing workpieces of varying thicknesses without changing components. For example, for thicker workpieces, the positioning baffle 3 can be lowered, while for thinner workpieces, it can be raised. The positioning baffle 3 prevents the workpiece from embedding too deeply in the support component 2, which would hinder processing. Additionally, the positioning mechanism 5 allows each support component 2 to be sequentially pressed and positioned. After positioning by the positioning mechanism 5, the workpiece can no longer push the support component 2 downwards to retract, thus fixing the workpiece and preventing it from loosening during processing, ensuring optimal processing results.

[0042] like Figures 1-5As shown, the position adjustment mechanism 4 includes two adjustment components respectively disposed on both sides of the housing 1; each adjustment component includes a connecting slide plate 41, an adjusting bolt 42, and a mounting block 43; the two connecting slide plates 41 of the two adjustment components are respectively located on the two outer surfaces of the housing 1 and their upper ends are respectively connected to the two sides of the positioning frame 3, and each connecting slide plate 41 is provided with a vertically extending strip-shaped sliding hole 44; in addition, in order to facilitate the movement of the connecting slide plate 41, a corresponding groove (not shown in the figure) for embedding the connecting slide plate 41 can be provided on the outer surface of the housing 1 to ensure the movement stability of the connecting slide plate 41; one end of each mounting block 43 is correspondingly inserted into a strip-shaped sliding hole 44 and fixed to the housing 1, and the other end of each mounting block 43 is provided with a first threaded hole 431 that penetrates both inside and outside, of course, the first threaded hole 431 does not penetrate to the end of the first end of the mounting block 43; the shank of each adjusting bolt 42 is correspondingly threaded into a first threaded hole 431 and abuts against the outer surface of the connecting slide plate 41. Therefore, the above-described configuration allows for the loosening or tightening of the connecting slide plate 41 by adjusting the inward and outward movement of the adjusting bolt 42. When the connecting slide plate 41 is loose, since it is connected to the positioning frame 3, the operator can manually pull or push the connecting slide plate 41 upwards or downwards to adjust the vertical position of the positioning frame 3. Of course, during the movement of the connecting slide plate 41, the mounting block 43 moves relative to the strip-shaped sliding hole 44 according to the principle of relative motion.

[0043] like Figures 1-4 As shown, preferably, each adjustment component also includes a scale 45; each scale 45 extends vertically and is mounted on the outer surface of the housing 1 and is located on one side of the corresponding connecting slide plate 41; each connecting slide plate 41 is provided with an indicator mark 46 for pointing to the scale of the scale 45. Therefore, by setting the mutually cooperating scale 45 and indicator mark 46, the operator can more accurately adjust the position of the connecting slide plate 41 and avoid position adjustment errors.

[0044] Preferably, the mounting block 43 is locked to the outer casing 1 by bolts, so that the mounting block 43 can be easily disassembled and assembled.

[0045] like Figures 5-7As shown, preferably, each support assembly 2 includes a top post 21 and an elastic element mounted on the top post 21; the first end of the top post 21 extends upward into the mounting cavity; the elastic element includes a spring 22 mounted in the insertion cavity 211 of the top post 21 and an abutment rod 23 whose first end is movably engaged in the insertion cavity 211 and whose second end is positioned in the mounting cavity. The spring 22 can provide a telescopic elastic force for the top post 21; the top post 21 can move up and down, and the top post 21 and the abutment rod 23 are in clearance fit. Therefore, by setting the spring 22, the top post 21 can have a telescopic effect, that is, the support assembly 2 has a telescopic effect. In addition, since the top post 21 and the abutment rod 23 are in clearance fit, the top post 21 can swing slightly relative to the abutment rod 23, and the swing amplitude should not be too large, that is, the top post 21 has a swingability, which in turn makes the support assembly 2 also have a swingability.

[0046] like Figures 1-5 As shown, preferably, the positioning mechanism 5 includes a push plate 51 and a knob 52; a mounting hole 13 extending into the mounting cavity is provided on the side of the housing 1; the push plate 51 is fitted into the mounting hole 13 and its first end face abuts against the side of the top post 21 of each support component 2 located at the edge; a limiting plate 8 covering the push plate 51 is also provided on the side of the housing 1, and a second threaded hole 81 corresponding to the push plate 51 is provided on the limiting plate 8. Specifically, the limiting plate 8 can be locked onto the housing 1 by bolts; the rod of the knob 52 is threaded from the outside to the inside into the second threaded hole 81 and passes through the second threaded hole 81 to abut against the second end face of the push plate 51. With the above arrangement, the push plate 41 can be used to push each top post 21 to fit in sequence until the positioning effect is achieved, so as to avoid the workpiece shifting position after installation. Specifically, by turning the knob 52 inward, the lever of the knob 52 can push the push plate 51 inward until the push plate 51 presses against the top post 21 and pushes each top post 21 to fit in sequence, so as to achieve the positioning of each top post 21. After releasing the knob 52, each top post 21 can be released. In this way, the spring 22 can use its extension force to make the top post 21 naturally return to its original position without external force.

[0047] like Figures 5-7 As shown, preferably, the outer end face of the top post 21 is flat and has an arc transition around it, so that it is not easy to scratch the workpiece.

[0048] like Figures 1-5 As shown, preferably, the positioning frame 3 includes a rectangular frame-shaped retaining edge 31 and retaining strips 32 connected to the middle of both sides of the retaining edge 31. Therefore, with the above arrangement, the retaining strips 32 can play a major supporting role for the workpiece, while the retaining edge 31 can support the edges of some larger workpieces to improve stability.

[0049] like Figures 1-5 As shown, in this embodiment, a partition plate 9, a first connector 6, and a second connector 7 are also included. The partition plate 9 is disposed in the mounting cavity and divides the mounting cavity into a first mounting cavity 11 and a second mounting cavity 12. Multiple support components 2 are matchedly disposed in both the first mounting cavity 11 and the second mounting cavity 12; specifically, the number of support components 2 in the first mounting cavity 11 and the second mounting cavity 12 is the same. The first connector 6 and the second connector 7 are respectively mounted on the outer shell 1. The first connector 6 connects to the first mounting cavity 11, and the second connector 7 connects to the second mounting cavity 12. By providing the first connector 6 and the second connector 7, it is convenient to input air into the first mounting cavity 11 and the second mounting cavity 12 for dust removal operations, and coolant can also be input to cool the interior of the first mounting cavity 11 and the second mounting cavity 12, etc. The appropriate medium can be selected according to actual needs to achieve different effects.

[0050] like Figures 1-5 As shown, in this embodiment, the multiple support components 2 in the first mounting cavity 11 and the second mounting cavity 12 are arranged in multiple rows, thereby ensuring that each support component 2 can provide corresponding support for the workpiece.

[0051] like Figure 2 As shown, in this embodiment, multiple connecting positioning members 10 are evenly distributed around the lower perimeter of the outer casing 1. These connecting positioning members 10 can be used to connect with fixing members (not shown in the figure) on the worktable of a working device (such as a pad printing machine) to position the bottom mold fixture of this invention on the working device. Each of these connecting positioning members 10 is provided with a slot (not shown in the figure), and the working device is provided with corresponding bolts and nuts that mate with the slots. By inserting the shank of the bolt into the slot and then tightening the nut, the bottom mold fixture is positioned by pressing the nut against the connecting positioning member 10, making it convenient to use.

[0052] The following describes the specific working principle of this utility model in order to help you understand it:

[0053] First, after installing this utility model, the worker pushes the workpiece downwards onto each support component 2, causing the top column 21 of the corresponding support component 2 to descend. This means the workpiece compresses the corresponding top column 21, and the top column 21 compresses the corresponding spring 22. Once the workpiece has descended to the preset position, the adjusting bolt 42 is loosened, and the vertical position of the positioning frame 3 is adjusted accordingly, so that the bottom surface of the workpiece abuts against the top surface of the positioning frame 3. Specifically, the position of the positioning frame 3 can be accurately adjusted using the scale 45. Next, by turning the knob 52 inwards, the push plate 51 is pressed against the adjacent top column 21. Then, these top columns 21 are tilted and swung away from the push plate 51 until each top column 21 abuts against the push plate, thus creating a positioning effect for the top column 21. This prevents the workpiece from pushing the top column 21 downwards. At this point, a corresponding groove for embedding the workpiece is formed above each descended top column 21. Then, the workpiece can be processed. After the workpiece is processed, it can be removed and replaced with a new workpiece for processing. When you want to change to a workpiece of a different thickness, simply loosen knob 52 to reset each top post 21. Similarly, the positioning stop frame 3 also needs to be reset. Then, push the new workpiece onto the support assembly 2 and repeat the above steps. That is, this utility model can position workpieces of different thicknesses without replacing other parts.

[0054] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
