[0036] The ejection mechanism is used in single-layer / multi-layer molds and in situations where the mold needs to be turned over to take out the product. The ejection structure in the prior art is divided into a single-layer ejection structure, a double-layer ejection structure (single ejector and single support), a double-layer ejection structure (double support) and a three-layer ejection structure (single ejector and double support). The above ejection structures are not related. Since different products have different requirements for demoulding and taking out the parts, under certain cost conditions, when the demoulding method cannot meet the requirements, the entire ejection structure needs to be replaced, which has a great impact on production cost and efficiency.

[0037] To this end, the present invention provides a modular ejection mechanism 100 .

[0038] See also Figures 1 to 8 In one embodiment of the utility model, the modular ejection mechanism 100 includes a central ejection assembly 10, a side inner support assembly 20 and a side outer support assembly 30; the central ejection assembly 10 includes a central frame 40, a first linear driving member 12 disposed at the bottom of the central frame 40, and a central top plate 11 drivingly connected to the first linear driving member 12; the side inner support assembly 20 includes a side frame 50, a second linear driving member 22 disposed at the bottom of the side frame 50, and a side inner support plate 21 drivingly connected to the second linear driving member 22; the side outer support assembly 30 includes a side outer support plate 32 and a third linear driving member 31 drivingly connected to the side outer support plate 32;

[0039] The side frame 50 is detachably mounted on the center frame 40, and the side outer support assembly 30 is detachably mounted on the side frame 50, so that the center ejection assembly 10 and the side inner support assembly 20, or the side inner support assembly 20 and the side outer support assembly 30, or the center ejection assembly 10, the side inner support assembly 20 and the side outer support assembly 30, are combined to form the modular ejection mechanism 100 with different functions.

[0040] In the present invention, the first linear driving member 12 , the second linear driving member 22 and the third linear driving member 31 may be oil cylinders.

[0041] The central ejection assembly 10, the side inner support assembly 20 and the side outer support assembly 30 of the modular ejection mechanism 100 of the utility model can all be used independently. The central ejection assembly 10 can work independently, and the central top plate 11 can be driven to rise and fall by the first linear drive 12, and the central ejection function can be set separately. The side inner support assemblies 20 located on both sides of the central ejection assembly 10 can also work independently, and the side inner support plate 21 can be driven to rise and fall by the second linear drive 22 to realize the single support function. At the same time, the side inner support assembly 20 can be combined with the central ejection assembly 10. The two cooperate to work, and the operation sequence is not in order. By driving the central top plate 11 and the side inner support plate 21 to rise and fall, the single-top single-support function is realized. The side outer support assembly 30 located on both sides of the central ejection assembly 10 can be combined with the side inner support assembly 20, and the two cooperate to work, and the operation sequence is not in order. The side outer support plate 32 is driven to rise and fall by the third linear drive 31, and the side inner support plate 21 is driven to rise and fall by the second linear drive 22, so that the lifting operation of a larger mold can be realized. In addition, the center ejection assembly 10, the side outer support assembly 30 and the side inner support assembly 20 can be spliced ​​and combined, and the three can work together in no particular order, realizing the function of single ejection and double supports, and can be applied to multi-layer mold demolding and occasions where the mold needs to be turned over to remove the product / insert.

[0042] The technical solution of the utility model is to set a central ejection assembly 10, and set a side outer support assembly 30 and a side inner support assembly 20 on both sides of the central ejection assembly 10. The three can be used separately, or the central ejection assembly 10 can be used in combination with the side inner support assembly 20, or the side inner support assembly 20 can be used in combination with the side outer support assembly 30, or the central ejection assembly 10, the side inner support assembly 20 and the side outer support assembly 30 can be used in combination, so as to realize a variety of ejection and lifting operations, which can be applicable to the ejection and demoulding operations of molds of different sizes and shapes, and thus can be applicable to different occasions of turning over the mold to take out products.

[0043] Furthermore, since the center ejector assembly 10 is disposed on the center frame 40, the side inner support assembly 20 is disposed on the side frame 50, and the side outer support assembly 30 is detachably mounted on the side frame 50, the center ejector assembly 10, the side inner support assembly 20, and the side outer support assembly 30 are independent of each other, so that the center ejector assembly 10, the side inner support assembly 20, and the side outer support assembly 30 of different specifications and sizes can be selectively replaced to achieve different ejection demolding methods.

[0044] At the same time, since the side outer support assembly 30 is detachably arranged on the side frame 50, the height difference between the side outer support assembly 30 and the side inner support assembly 20 in the height direction is small, so that the height of the entire ejection device can be reduced, and a larger height space can be reserved, so as to facilitate increasing the ejection stroke of the ejection device.

[0045] See also Figure 1 , Figure 2 As shown, in an embodiment of the present utility model, the center ejection assembly 10 is further provided with a first guide structure for guiding the lifting and lowering of the center top plate 11, the first guide structure includes a plurality of first guide rods 13, the plurality of first guide rods 13 are fixed below the center top plate 11, a plurality of first guide holes are penetrated through the center frame 40, and the plurality of first guide rods 13 are slidably matched with the plurality of first guide holes one-to-one.

[0046] In the above embodiment, the center frame 40 includes a limit plate, and the first linear drive member 12 can be a first oil cylinder. The cylinder body of the first oil cylinder is fixedly installed on the bottom of the limit plate, and the rod body of the first oil cylinder passes through the limit plate and is connected to the center top plate 11. The first guide hole is opened in the limit plate, and the first guide rod 13 passes through the first guide hole and slides with the first guide hole. When the first linear drive member 12 drives the center top plate 11 to rise and fall, multiple first guide rods 13 slide along the corresponding first guide holes respectively to guide the lifting and lowering of the center top plate 11.

[0047] See also Figure 2 , Figure 5 As shown, in an embodiment of the utility model, a first mounting portion is provided on both sides of the center frame 40, and a second mounting portion is provided on the side where the two side frames 50 are close to each other, and the first mounting portion and the second mounting portion are detachably connected so that the two side frames 50 can be detachably mounted on both sides of the center frame 40, and are used to splice and combine the side outer support assembly 30 and the side inner support assembly 20 to form a first combined lifting member.

[0048] In the present invention, the center frame 40 also includes connecting plates arranged on both sides of the limiting plate, the connecting plates protrude from the limiting plate, and the above-mentioned first mounting portion is arranged on the connecting plates. Among them, the first connecting portion can be a first mounting hole position opened on the connecting plate, and the first mounting hole position corresponds to the mounting position preset on the mold shifting device, and the center frame 40 can be installed to the mounting position of the mold shifting device. Among them, the first mounting hole position is opened at the upper end of the connecting plate, and the second mounting portion can be a second mounting hole position opened on the side of the side frame 50 close to the center frame 40. Such an arrangement can facilitate the detachable connection of the side frame 50 and the center frame 40, and can make the center ejection assembly 10 installed on the center frame 40 and the side inner support assembly 20 installed on the side frame 50 modularly arranged, and can be selected and installed on the equipment according to the use requirements.

[0049] See also Figure 3 , Figure 4 , Figure 5 , Figure 6In an embodiment of the utility model, two side inner support assemblies 20 are provided, and a first synchronization assembly is provided between the two side inner support assemblies 20. The first synchronization assembly is used for synchronous lifting of the inner support plates 21 on both sides. The first synchronization assembly includes a synchronization shaft 24. Both ends of the synchronization shaft 24 are respectively provided on the two side frames 50 and are rotatably connected to the two side frames 50. Gears 25 are provided at both ends of the synchronization shaft 24. A rack rod 26 is provided at the bottom of the side inner support plate 21. The rack rod 26 is slidably provided on the side frame 50 and meshes with the gear 25 for transmission.

[0050] In the above embodiment, since the inner support assemblies 20 on both sides can be respectively arranged on both sides of the central ejection assembly 10, and the two inner side support plates 21 are respectively driven by different second linear driving members 22, the lifting and lowering strokes of the two inner side support plates 21 may be asynchronous. For this reason, a first synchronization assembly is provided to synchronously lift and lower the two inner side support plates 21.

[0051] Furthermore, when one side inner support plate 21 is lifted or lowered, the rack bar 26 disposed at the bottom of the side inner support plate 21 is lifted or lowered accordingly, and the lifting or lowering of the rack bar 26 drives the gear 25 to rotate accordingly, and the gear 25 is disposed on the synchronization shaft 24, thus driving the synchronization shaft 24 to rotate. When the synchronization shaft 24 rotates, it can drive the other gear 25 to rotate at the same speed, so that the other rack bar 26 is lifted or lowered at the same speed. When the other side inner support plate 21 is driven to lift or lower, the lifting or lowering speeds of the two can be ensured to be the same, and when both are lifted or lowered from the same initial height or different initial heights, or when both are lifted or lowered from the same initial height or different initial heights, the two can be lifted or lowered synchronously.

[0052] In addition, the modular ejection mechanism 100 of the present invention further includes a bearing seat 52 . A bearing seat 52 is disposed at the bottom of each side frame 50 , and the end of the synchronization shaft 24 is rotatably mounted on the bearing seat 52 .

[0053] By providing the bearing seat 52 , the rotation smoothness of the synchronization shaft 24 can be improved, so that the lifting and lowering of the inner support plates 21 on both sides can be synchronized more accurately.

[0054] See also Figure 3 , Figure 4 As shown, in an embodiment of the utility model, the side inner support assembly 20 also includes a plurality of second guide rods 23, the plurality of second guide rods 23 are fixed to the bottom of the side inner support plate 21, the side frame 50 is penetrated by a plurality of second guide holes, and the plurality of second guide rods 23 are slidably matched with the plurality of second guide holes in a one-to-one manner.

[0055] In the above embodiment, the second linear drive member 22 for the side inner support assembly 20 can be a second oil cylinder, the cylinder body of the second oil cylinder is fixed to the top of the side frame 50, and the rod body of the second oil cylinder passes through the side frame 50 to be connected to the side inner support plate 21. Similar to the center ejection assembly 10, during the lifting and lowering of the side inner support assembly 20, the second guide rod 23 can be slidably matched with the second guide hole to make the side inner support plate 21 more stable during the lifting and lowering movement.

[0056] Among them, the side frame 50 is penetrated by a plurality of second guide holes along its height direction. Since the second guide rod 23 is installed and fixed on the bottom of the side inner support plate 21, and the second guide rod 23 slides with the second guide hole, when the side inner support plate 21 is raised or lowered, the second guide rod 23 is also raised or lowered accordingly, and slides in the second guide hole. Therefore, the deflection and tilt of the side inner support plate 21 can be limited by the sliding limit cooperation between the second guide rod 23 and the side frame 50, thereby improving the operation stability of the side inner support plate 21.

[0057] Continue reading Figure 3 , Figure 4 In an embodiment of the utility model, the rack rod 26 and the plurality of second guide rods 23 are spaced apart and distributed at the bottom of the side inner support plate 21, and the rack rod 26 cooperates with the plurality of second guide rods 23 to form a second guide structure for guiding the lifting and lowering of the side inner support plate 21.

[0058] In the above-mentioned embodiment, the rack rod 26 can be one of the second guide rods 23. By opening a plurality of tooth grooves 261 arranged along the longitudinal direction on one of the second guide rods 23, the second guide rod 23 forms a rack rod 26 with a rack structure, so that there is no need to install an additional rack structure on the side inner support assembly 20, and it can cooperate with the gear 25. When the side inner support plate 21 is guided by the second guide rod 23 when it is raised and lowered, the rack rod 26 can be raised and lowered accordingly, thereby driving the gear 25 to rotate.

[0059] Alternatively, the rack rod 26 can be installed on the basis of the original second guide rod 23, and a through hole can be reserved on the side frame 50 for the rack rod 26 to slide through. When the side inner support plate 21 is raised or lowered, the rack rod 26 can realize the guiding function through the sliding cooperation between the reserved through hole and the rack rod 26.

[0060] See also Figure 3 , Figure 4 As shown, in order to ensure that the two side inner support plates 21 are lifted and lowered from the same initial position, in an embodiment of the utility model, a first limit member 51 is further provided on the side frame 50, and the first limit member 51 includes a first threaded seat arranged at the top of the side frame 50, and a first screw is threadedly installed on the first threaded seat, and a first positioning portion is formed on the top of the first screw, and the first positioning portion is used to abut against the bottom of the side inner support plate 21.

[0061] In the above embodiment, since the first positioning portion can be raised and lowered relative to the side frame 50, and the side inner support plate 21 is in contact with the first positioning portion, the initial height of the side inner support plate 21 can be changed. By adjusting the initial height of the inner support plates 21 on both sides, the inner support plates 21 on both sides can be adjusted to a specified initial height. When the two side inner support plates 21 are supporting the mold, the two side inner support plates 21 can adapt to the outer shape layout of the contact portion between the bottom surface of the mold and the side inner support plates 21, ensuring that they are completely in contact with the bottom surface of the mold.

[0062] See also Figure 7 As shown, in an embodiment of the utility model, the side outer support assembly 30 also includes a third guide structure for guiding the lifting and lowering of the side outer support plate 32, and the third guide structure includes a plurality of third guide rods 33, and the plurality of third guide rods 33 are fixed to the bottom of the side outer support plate 32, and a plurality of third guide holes are formed through the side frame 50, and the plurality of third guide rods 33 are slidably matched with the plurality of third guide holes in a one-to-one manner.

[0063] Among them, the number of the third guide rods 33 can be four, and the four third guide rods 33 are evenly spaced and distributed at the bottom of the side outer support plate 32, and the number of the third guide holes on the side frame 50 can be correspondingly set to four. The third linear drive member 31 can be set as a third oil cylinder, the cylinder body of the third oil cylinder is installed at the bottom of the side frame 50, and is spaced from the second linear drive member 22. The rod body of the third oil cylinder passes through the side frame 50 and is connected to the side outer support plate 32. When the third oil cylinder drives the side outer support plate 32 to rise and fall, the multiple third guide rods 33 slide along the third guide holes, and when the side outer support plate 32 rises to lift the mold, the running stability of the side outer support plate 32 can be improved to prevent the side outer support plate 32 from deflecting.

[0064] See also Figure 1 , Figure 7 As shown, in an embodiment of the utility model, two side outer support assemblies 30 are provided, and a second synchronization assembly is provided between the two side outer support assemblies 30. The second synchronization assembly is used for synchronous lifting and lowering of the outer support plates 32 on both sides. The second synchronization assembly includes a connecting member 34. The two ends of the connecting member 34 are respectively provided under the outer support assemblies 30 on both sides, and are respectively connected to the third guide rods 33 of the corresponding side outer support assemblies 30.

[0065] In the utility model, since the third guide rod 33 will rise and fall with the side outer support plate 32, when a connecting member 34 is provided and the two ends of the connecting member 34 are respectively connected to the third guide rod 33 of the outer support assembly 30 on both sides, the two side outer support plates 32 can be raised and lowered at the same speed, thereby facilitating the cooperation of the two side outer support plates 32 for demoulding of larger structures.

[0066] In addition, a second limit member 53 can also be set at the top of the side frame 50. The second limit member 53 includes a second threaded seat arranged at the top of the side frame 50. The second threaded seat is threaded with a second screw. The top of the first screw forms a second positioning portion, and the second positioning portion is used to abut against the bottom of the side inner support plate 21.

[0067] In the above-mentioned embodiment, the principle of limiting the side inner support plate 21 by the second limiting member 53 is the same as that of changing the initial height of the side outer support plate 32 because the side outer support plate 32 abuts against the second positioning portion at the initial position. When the two side outer support plates 32 are supporting the mold, they can adapt to the outer shape layout of the contact portion between the bottom surface of the mold and the side outer support plates 32 to ensure that they are in full contact with the bottom surface of the mold.

[0068] In the embodiment of the utility model, one end of the third guide rod 33 is detachably connected to the connecting member 34, and / or the other end of the third guide rod 33 is detachably connected to the side outer support plate 32, and the third linear drive member 31 is detachably connected to the side frame 50, so that the side inner support assembly 20 is separated from the side inner support assembly 20, or the side inner support assembly 20 is combined with the side outer support assembly 30 to form the second combined lifting member;

[0069] The central frame 40 and the side frame 50 are detachably connected so that the second combined lifting member and the central ejection assembly 10 are combined to form a third combined lifting member.

[0070] In the utility model, when one end or both ends of the third guide rod 33 are detachably connected to the connecting member 34 or the side outer support plate 32, the end of the third guide rod 33 can be in a separated state at this detachable connection end, so that the third guide rod 33 can be separated from the side frame 50 from this end, so that the third guide rod 33, the side outer support plate 32 and the connecting member 34 are separated from the side frame 50, and at the same time, the third linear drive member 31 is detachably connected to the side frame 50, so that the third linear drive member 31 is separated from the side frame 50, so that the side outer support assembly 30 can be modularly combined with the side inner support assembly 20.

[0071] At the same time, when the side inner support assembly 20 and the side outer support assembly 30 are combined to form a second combined lifting piece, since the center frame 40 and the side frame 50 are detachably connected, the center ejection assembly 10 can also be detachably combined with the second combined lifting piece to form a third combined lifting piece.

[0072] See also Figure 1 , Figure 6As shown, in the embodiment of the utility model, the connecting member 34 is a connecting plate, and first avoidance grooves 341 are provided on both sides of the connecting plate. When the side inner supporting assembly 20 and the side outer supporting assembly 30 are combined to form the second combined supporting member, the first avoidance grooves 341 are used to avoid the second linear driving member 22 and the third linear driving member 31;

[0073] A second avoidance groove 342 is formed in the middle of the connecting plate. When the side outer support assembly 30 , the side inner support assembly 20 and the center ejection assembly 10 are combined to form the third combined lifting member, the second avoidance groove 342 is used to avoid the first linear driving member 12 .

[0074] In the above-mentioned embodiment, by providing the first avoidance groove 341 on both sides of the connecting plate, when the side inner support assembly 20 and the side outer support assembly 30 are combined to form the second combined lifting member, the third linear drive member 31 and the second linear drive member 22 can be avoided, so that the third linear drive member 31 and the second linear drive member 22 can have sufficient setting space. On the basis of achieving the synchronization of the strokes of the two side outer support plates 32, when the third linear drive member 31 drives the side outer support plate 32, and when the second linear drive member 22 drives the side inner support plate 21, the side outer support plate 32 and the side inner support plate 21 have a sufficiently long lifting action stroke.

[0075] Furthermore, since the first synchronous structure adopts the structure of the synchronous shaft 24, the gear 25, and the rack rod 26, when the two side inner support plates 21 are synchronously lifted and lowered, the side inner support plates 21 will not be limited, thereby avoiding interference with the lifting and lowering stroke of the side inner support plates 21.

[0076] In addition, when the side outer support assembly 30 and the side inner support assembly 20 are separated from the central ejection assembly 10 and used separately as the second combined lifting member, since the connecting plate will not interfere with the central ejection assembly 10, the second avoidance groove 342 is not required to be provided on the connecting plate to avoid the first linear drive member 12.

[0077] See also Figure 1 As shown, in an embodiment of the present utility model, when the side outer support assembly 30 is spliced ​​and combined with the side inner support assembly 20, and when the side outer support assembly 30 is spliced ​​and combined with the side inner support assembly 20 and the center ejection assembly 10, the side outer support plate 32 is enclosed on the outer peripheral side of the side inner support plate 21.

[0078] In the above-mentioned embodiment, the side outer support plate 32 can be arranged in a "U" shape, and when the side outer support assembly 30 is spliced ​​and combined with the side inner support assembly 20 to form the first combined lifting member, and when the side outer support assembly 30 is spliced ​​and combined with the side inner support assembly 20 and the central ejection assembly 10 to form the third combined lifting member, the side inner support plate 21 is arranged on the inner side of the side outer support plate 32, and the side outer support plate 32 surrounds the side inner support plate 21. Such an arrangement can save the arrangement space of the side outer support plate 32, so that the size of the entire ejection device in the width direction will not be too large, and at the same time, the size of the side outer support plate 32 will not be too small, which will affect the lifting and ejection operation of the side outer support plate 32.

[0079] In the embodiment of the utility model, the side inner support plate 21 can be composed of two parts, one of which is the bottom mounting plate, and the other is the first lifting plate arranged on the top of the bottom mounting plate, and the first lifting plate is provided with a plurality of lifting slots, so that the mold can be connected to the lifting plate. The side outer support plate 32 can also be composed of two parts, one of which is the bottom mounting plate, and the other is the second lifting plate arranged on the top of the bottom mounting plate, and the second lifting plate is also provided with a plurality of slots, which can also be used to connect the mold.
