[0038] As Figures 1-5As shown in the figure, a fully automatic injection mold 1 for stainless steel filter screens is provided, including: an injection mold 1, the injection mold 1 includes a moving mold 2, a fixed mold 3 arranged above the moving mold 2, a first slider assembly 4 arranged on the front side of the moving mold 2, and a second slider assembly 5 arranged on the rear side of the moving mold 2. One or more core columns 6 are arranged on the moving mold 2 from left to right; a feeding device 7, the feeding device 7 is arranged on the left side of the mold body, and the feeding device 7 is used to move two parallel stainless steel filter screens between the first slider assembly 4 and the second slider assembly 5; a discharging device 8, the discharging device 8 is arranged on the right side of the mold body, and the discharging device 8 is used to clamp and discharge the injection-molded stainless steel filter screen; a driving device 35, the driving device 35 is connected to the feeding device 7 and the discharging device 8, and the driving device 35 simultaneously drives the feeding device 7 to feed and the discharging device 8 to discharge; wherein, the first slider assembly 4 and the second slider assembly 5 drive to press the stainless steel filter screen and fit with the outer peripheral surface of the core column 6 to form a shape, and the fixed mold 3 and the moving mold 2 are closed to inject and mold the upper side, lower side and both sides of the stainless steel filter screen.

[0039] In a circular filter on the market, the main body is a stainless steel circular ring structure, and injection molding is carried out at the circumferential positions of the upper edge and the lower edge of the main body and at the positions perpendicular to the upper and lower edges. According to this structural feature, the processing technology adopted on the market is: cutting the stainless steel filter screen into appropriate sizes, bending the stainless steel mesh and then welding it into a circular filter screen structure, and then placing the circular filter screen in the injection mold 1 to inject mold the upper edge, lower edge and the part between the upper edge and the lower edge of the circular filter screen, thus completing the entire production process.

[0040] In the above production process, since it is necessary to involve multiple devices or move and process the stainless steel filter screen between multiple workstations, it causes technical problems of increased cost and low production efficiency.

[0041] In response to this, a fully automatic injection mold 1 for stainless steel filter screens is provided. Referring to Figure 11 As shown in the figure, during the injection mold 1, the shaping of the stainless steel filter screen is completed while injection molding is carried out, so that the process can be simplified and the production efficiency can be greatly improved.

[0042] The specific driving process is as follows. In the present utility model, the control system can be devices such as a PLC or a control panel, which is used to receive signals from various devices or components. By using coils of two stainless steel filters, the feeding device 7 is used to clamp and move the two stainless steel filters into the injection mold 1. When the first slider assembly 4 and the second slider assembly 5 move relative to the core column 6 on the moving mold 2, under the pressing action of the first slider assembly 4 and the second slider assembly 5, the stainless steel filter is pressed against the core column 6 to form a circular ring structure. Under the mold closing action of the fixed mold 3 and the moving mold 2, injection molding is carried out on the upper edge, lower edge of the circular ring-shaped stainless steel filter and the intersection position of the two stainless steel meshes. Then, under the action of the discharging device 8, the injection-molded circular ring-shaped stainless steel filter is taken out for subsequent peeling operation of individual circular ring-shaped stainless steel filters. In the above, the feeding device 7 and the discharging device 8 are linked by a driving device 35. For example, after the injection molding of the circular ring-shaped stainless steel filter is completed, the driving device 35 drives the discharging device 8 to discharge the injection-molded circular ring-shaped stainless steel filter. At the same time, the feeding device 7 feeds the two stainless steel filters into the injection mold 1.

[0043] Reference Figures 5-7 As shown in FIGS. 15-16, the first slider assembly 4 includes a first hydraulic component 9, a first forming block 10 connected to the telescopic end of the first hydraulic component 9, and a first slide rail 11 disposed below the first forming block 10; the second sliding assembly includes a second hydraulic component 12, a second forming block 13 connected to the telescopic end of the second hydraulic component 12, and a second slide rail 14 disposed below the second forming block 13; wherein, on the opposite surfaces of the first forming block 10 and the second forming block 13, there are first semi-circular grooves 15 that cooperate with the core column 6; the second forming block 13 is provided with second semi-circular grooves 16 that cooperate with the first semi-circular grooves 15; the first forming block 10 and the second forming block 13 are combined to form an injection molding space for the stainless steel filter together with the upper mold, the lower mold, and the core column 6.

[0044] The above provides a feasible structural setting of the first slider assembly 4 and the second slider assembly 5. According to production requirements, the number of the first semi-circular grooves 15 and the second semi-circular grooves 16 can be set without limitation. Specifically in this embodiment, 4 groups are adopted. After the first semi-circular grooves 15 and the second semi-circular grooves 16 are combined, they cooperate with the core column 6 of the moving mold 2 to form the required circular ring structure. The lower parts of the first forming block 10 and the second forming block are respectively installed with the first slide rail 11 and the second slide rail 14, so as to facilitate the movement of the first forming block 10 and the second forming block 13. Among them, the first slide rail 11 and the second slide rail 14 can share a guide rail, and the first hydraulic component 9 and the second hydraulic component 12 can adopt the form of hydraulic cylinders.

[0045] In the specific driving process, driven by the first hydraulic component 9 and the second hydraulic component 12, the first forming block 10 and the second forming block 13 move relative to each other on the first slide rail 11 and the second slide rail 14. Since the two stainless steel filter meshes are located on both sides of the core column 6, when the first forming block 10 and the second forming block 13 move into place, the two stainless steel filter meshes are pressed against the core column 6 to form an annular structure.

[0046] Reference Figure 4 and Figure 6 、 7 As shown in FIGS. 15 and 16, the present utility model further includes a preforming block 17 provided on the moving mold 2. The preforming block 17 is placed on the left side of the core column 6. A first arc-shaped groove 18 is provided on the surface of the first forming block 10 opposite to the second forming block 13, and a second arc-shaped groove 19 is provided on the second forming block 13 to cooperate with the first arc-shaped groove 18. Wherein, when the first forming block 10 and the second forming block 13 are combined; the first arc-shaped groove 18, the second arc-shaped groove 19 and the preforming block 17 perform partial forming on the stainless steel filter mesh.

[0047] During the production process, due to the lack of effective positioning of the stainless steel filter mesh, such as how to ensure the injection molding of the first end of the stainless steel filter mesh when two parallel stainless steel meshes are combined by the first forming block 10 and the second forming block 13. In view of this technical problem, a technical solution is proposed, that is, when injecting for the first time, preform a semi-annular stainless steel filter mesh. Among them, the preformed semi-annular stainless steel filter mesh is located on the leftmost side of the core column 6. At the same time, as the first end of the next injection, that is, after the feeding device 7 feeds the material, the preformed semi-annular stainless steel filter mesh contacts the rightmost core column 6, which can locate the first end position of the annular stainless steel filter mesh and is also convenient for the subsequent first slider assembly 4 and second slider assembly 5 to press the stainless steel filter meshes on both sides of the core column 6.

[0048] Specifically, a preforming block 17 is arranged at the left side position of the core column 6. The right side of the preforming block 17 is semi-circular, and the width of the preforming block 17 is the width of the two stainless steel filter meshes. A first arc-shaped groove 18 is arranged on the first forming block 10, and the first arc-shaped groove 18 has a quarter arc. A second arc-shaped groove 19 is arranged on the second forming block 13, and the second arc-shaped groove 19 has a quarter arc. When the first forming block 10 and the second forming block 13 move relative to each other to the preforming block 17, the first arc-shaped groove 18, the second arc-shaped groove 19 and the preforming block 17 cooperate to form half of the annular stainless steel filter mesh. Thus, in the next injection, the preformed semi-annular stainless steel filter mesh is used as a positioning element and placed on the rightmost core column 6, and so on, solving the positioning problem of feeding the two stainless steel filter meshes.

[0049] Reference Figures 6-7 As shown in FIGS. 15 and 16, retractable first shaping rods 20 are respectively arranged between adjacent first semi-circular grooves 15; second shaping rods 21 cooperating with the first shaping rods 20 are respectively arranged between adjacent second semi-circular grooves 16; the extending length of the first shaping rods 20 gradually increases from the feeding end of the moving mold 2 along the discharging end direction, and the extending length of the second shaping rods 21 gradually increases from the feeding end of the moving mold 2 along the discharging end direction; wherein, when the moving mold 2 and the fixed mold 3 are clamped, the first shaping rods 20 and the second shaping rods 21 sequentially extend from the discharging end of the moving mold 2 along the feeding end direction to press and shape the stainless steel filter screens placed on both sides of the core column 6.

[0050] To achieve the shaping of the stainless steel filter screen, retractable first shaping rods 20 and retractable second shaping rods 21 are respectively arranged on the first forming block 10 and the second forming block 13, and the first shaping rods 20 and the second shaping rods 21 are respectively distributed along the positions of the first semi-circular grooves 15 and the second semi-circular grooves 16.

[0051] Since when the first forming block 10 and the second forming block 13 move relatively, if they are combined at the same time, due to the length of the stainless steel filter screen not being able to meet the structure of forming an annular filter net, problems such as fracture or poor forming quality will occur. Therefore, a plurality of retractable first shaping rods 20 and second shaping rods 21 are respectively arranged on the first forming block 10 and the second forming block 13. When the first forming block 10 and the first forming block 10 move relatively, since the rightmost side of the core column 6 is a preformed semi-annular stainless steel filter screen, which is the head end of the annular stainless steel filter screen, therefore, the extending lengths of the first shaping rods 20 and the second shaping rods 21 close to the rightmost core column 6 are the longest, and the rightmost first shaping rods 20 and second shaping rods 21 extend first to meet the requirement of the stainless steel length at the rightmost side during mold clamping. Furthermore, along the feeding end direction of the moving mold 2, the first shaping rods 20 and the second shaping rods 21 extend successively so that the stainless steel filter screen meets the length at each core column 6 position. Therefore, when the first forming block 10 and the second forming block 13 are combined, the lengths of the two stainless steel materials can meet the requirement of being pressed against the core column 6.

[0052] Refer to Figures 8-9As shown, the feeding device 7 includes a third slide rail 24, a first connecting seat 25 mounted on the third slide rail 24, a first lifting cylinder 26 mounted on the first connecting seat 25, a base block 27 mounted on the telescopic end of the first lifting cylinder 26, and a first clamping cylinder 28 mounted on the base block 27. Among them, the front side and the rear side of the base block 27 are respectively provided for the stainless steel filter screen to pass through. The clamping ends of the first clamping cylinder 28 are respectively placed on the front side and the rear side of the base block 27, and the first clamping cylinder 28 drives to clamp the stainless steel filter screen on the front side and the rear side of the base block 27.

[0053] The above provides a feasible structure of the feeding device 7. The feeding device 7 mainly includes a third slide rail 24, a first connecting seat 25, a first lifting cylinder 26, a base block 27, and a first clamping cylinder 28. The feeding device 7 mainly realizes the clamping and transportation of two stainless steel filter screens, and uses the front side and the rear side of the base block 27 to form a spacing for the stainless steel filter screen to move. For the convenience of the stainless steel filter screen to move, guide wheels can be set at the left side position of the base block 27.

[0054] The specific use process is as follows: The feeding device 7 can be connected to the stripper plate of the moving mold 2. After the injection molding of the stainless steel filter screen is completed, the first clamping cylinder 28 clamps the stainless steel filter screen, so that the two stainless steel strips are in a tensioned state. Refer to Figures 17-18 , the moving mold 2 is demolded, and the stripper plate of the moving mold 2 and the feeding device 7 move upward as a whole. At this time, the formed ring-shaped filter screen is separated from the core column 6. In view of the fact that when the lower edge position of the ring-shaped filter screen is injection molded, a part of the lower edge position is placed in the cavity position of the moving mold 2, so the first lifting cylinder 26 drives upward, and the injection molded ring-shaped stainless steel filter screen is separated from the cavity position of the moving mold 2. Under the action of the driving device 35, after the first connecting seat 25 moves to the specified position to the right on the third slide rail 24, the first lifting cylinder 26 moves downward. When the stripper plate of the moving mold 2 is reset, it drives the entire feeding device 7 to move synchronously. At this time, the two stainless steel filter screen coils are on both sides of the core column 6. Furthermore, when the injection mold 1 is closed, the first shaping rod and the second shaping rod are used to extend to adjust the length of the stainless steel filter screen, and the first forming block 10 and the second forming block 13 are used to shape and press the stainless steel filter screen coil to position the stainless steel filter screen coil. Thus, the first clamping cylinder 28 releases the clamping of the stainless steel filter screen coil, and under the drive of the driving device 35, the first connecting seat 25 moves to the left and resets on the third slide rail 24, and so on.

[0055] Refer to Figure 8 and Figure 10As shown, the unloading device 8 includes a fourth slide rail 29, a second connecting seat 30 installed on the fourth slide rail 29, a second lifting cylinder 31 installed on the second connecting seat 30, and a second clamping cylinder 32 installed on the second connecting seat 30; the second clamping cylinder 32 is used to clamp the stainless steel filter after injection molding.

[0056] The above is an implementable structure of the unloading device 8. The unloading device 8 can be installed on the stripping plate of the movable mold 2. Under the coordinated action of the unloading device 8 and the loading device 7, the annular stainless steel filter after injection molding can be unloaded. After the injection mold 1 completes the injection molding work, the first clamping cylinder 28 of the loading device 7 clamps the stainless steel filter roll, and the second clamping cylinder 32 clamps the stainless steel filter roll. Under the upward drive of the stripping plate of the movable mold 2, the stripping plate of the movable mold 2 drives the loading device 7 and the unloading device 8 to move upward as a whole. At this time, the annular stainless steel filter after injection molding is separated from the core column 6. The first lifting cylinder 26 and the second lifting cylinder 31 are lifted upward to lift the stainless steel filter roll upward and away from the cavity position on the movable mold 2. Under the action of the driving device 35 , the first connecting seat 25 moves to the right along the third slide rail 24, and the second connecting seat 30 moves to the right along the fourth slide rail 29, thereby completing the unloading operation, and then the first lifting cylinder 26 and the second lifting cylinder 31 move downward, and then, the stripping plate of the movable mold 2 is reset, and the two stainless steel filter mesh rolls are placed on both sides of the core column 6 of the injection mold 1. When the injection mold 1 outputs a mold closing signal, the first clamping cylinder 28 and the second clamping cylinder 32 release the clamping, and under the action of the driving device 35, the first connecting seat 25 and the second connecting seat 30 move to the left and reset.

[0057] refer to Figure 8 As shown, the driving device 35 includes a telescopic member 33 and a connecting rod 34 arranged at the driving end of the telescopic member 33; wherein, the connecting rod 34 is connected to the first connecting seat 25 and the second connecting seat 30; when the telescopic member 33 drives the connecting rod 34 to extend and retract, the first connecting seat 25 moves on the third slide rail 24, and the second connecting seat 30 moves on the fourth slide rail 29.

[0058] The driving device 35 serves as a driving force for realizing synchronous driving of the loading device 7 and the unloading device 8. The driving device 35 includes a telescopic member 33 and a connecting rod 34. The telescopic member 33 can adopt a member with telescopic function such as a cylinder or a hydraulic cylinder. For the convenience of installation, it can be connected to the injection mold 1 by using a bracket. The connecting rod 34 is arranged at the output end of the telescopic member 33. The first connecting seat 25 and the second connecting seat 30 are sleeved on the connecting rod 34, so that when the telescopic member 33 is driven, the synchronous driving of the first connecting seat 25 and the second connecting seat 30 is realized.

[0059] refer to Figure 12As shown, a guiding block 22 is provided at the upper part of the core column 6, and an inclined surface for guiding the stainless steel coil is provided at the circular peripheral edge of the guiding block 22.

[0060] Since the edge position of the stainless steel filter screen is uneven, when the core column 6 abuts against the moving die 2, there may be problems of friction or jacking. To this end, it is necessary to install a guiding block 22 at the upper part of each core column 6. Then, when the stripper plate of the moving die 2 moves upward, under the action of the inclined surface of the guiding block 22, the two stainless steel filter screens are guided to both sides of the core column 6.

[0061] Reference Figures 13-14 As shown, pressing edges 23 are respectively provided at the side edges of the first semi-circular groove 15 and the second semi-circular groove 16; when the fixed die 3 and the moving die 2 are clamped, the pressing edge 23 of the first semi-circular groove 15 and the pressing edge 23 of the second semi-circular groove 16 are pressed against each other to form an indentation on the stainless steel filter screen.

[0062] Since it is necessary to separate the row of annular stainless steel filter meshes into individual forms subsequently, for this, it is required to form creases that are easy to separate at both side positions of the annular stainless steel filter mesh. That is, by setting the pressing edges 23 on the first semi-circular groove 15 and the second semi-circular groove 16, when the first forming block 10 and the second forming block 13 are combined, a small gap is reserved at the pressing positions on both sides of the annular stainless steel filter mesh, so as to form an indentation for easy separation.

[0063] The above does not impose any limitation on the technical scope of the present invention.
