Description

Technical Field

[0001] This invention relates to the field of machinery, and in particular to a mold-removal mechanism and method. Background Technology

[0002] Currently, repairs require the entire mold to be removed from the machine and disassembled to remove the core component, the mold core, for inspection. The current problems with mold repair are: (a) removing the mold from the machine requires disassembling auxiliary equipment such as water, electricity, gas, and oil systems; (b) repositioning and calibrating the robotic arm after remounting is difficult; and (c) the core components are too heavy for manual removal from the machine. Therefore, the current repair method cannot quickly and effectively remove the core component of the mold, the mold core, for inspection.

[0003] Therefore, it is necessary to provide a demolding mechanism and demolding method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a mold removal mechanism and method that can quickly and effectively remove the core part of the mold, namely the mold core, for inspection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold removal mechanism for cooperating with a hydraulic mechanism to quickly remove the mold core from the mold. The mold includes a male mold mechanism and a female mold mechanism that cooperate with each other. The mold core is positioned on the male mold mechanism. In the initial open state of the male mold mechanism and the female mold mechanism, the mold core is exposed on the side of the male mold mechanism facing the female mold mechanism. The mold removal mechanism is characterized in that it includes a first fixture plate and a second fixture plate. The first fixture plate and the second fixture plate are spaced apart and connected to each other. Both the first fixture plate and the second fixture plate have through holes on their surfaces for fasteners to pass through.

[0006] As a further improvement of the present invention, the mold disassembly mechanism further includes a guide mechanism, which is capable of aligning and cooperating with the corresponding structures of the male mold mechanism and the female mold mechanism.

[0007] As a further improved technical solution of the present invention, the guiding mechanism includes a first guide sleeve, the first fixture plate includes a first side and a second side arranged opposite to each other, the first side faces the mold mechanism, the second side faces the second fixture plate, and the first guide sleeve is located on the first fixture plate and passes through the first side and the second side of the first fixture plate.

[0008] As a further improved technical solution of the present invention, the guiding mechanism includes a second guide post, the second fixture plate includes a third side and a fourth side arranged opposite to each other, the third side faces the first fixture plate, the fourth side faces the master mold mechanism, and the second guide post is fixed to the second fixture plate and exposed on the fourth side of the second fixture plate.

[0009] As a further improvement of the present invention, the demolding mechanism further includes an elastic element located between the first fixture plate and the second fixture plate, with one end of the elastic element abutting against the first fixture plate and the other end of the elastic element abutting against the second fixture plate.

[0010] As a further improvement of the present invention, the demolding mechanism further includes a first column, which is positioned with the first fixture plate and / or the second fixture plate, and the elastic element is a helical spring forming a receiving space, with the first column extending into the receiving space.

[0011] As a further improved technical solution of the present invention, the demolding mechanism further includes a second column, one end of which is fixedly connected to the surface of one of the first fixture plate and the second fixture plate, and the other end of which is movably connected to the surface of the other of the first fixture plate and the second fixture plate.

[0012] As a further improvement of the present invention, the demolding mechanism further includes a lifting ring, which is located on the top edge of the first fixture plate and the second fixture plate.

[0013] To achieve the above objectives, the present invention adopts the following technical solution two: a demolding method, using the demolding mechanism described above to quickly remove the mold core from the mold, the demolding method comprising the following steps: (1) a hydraulic mechanism opens the male mold mechanism and the female mold mechanism of the mold from a closed initial state to a first state with a first interval distance, removes the first fastener on the male mold mechanism for fixing the mold core, and after the gantry crane is mounted, places the demolding mechanism between the male mold mechanism and the female mold mechanism; (2) the hydraulic mechanism pulls the male mold mechanism and the female mold mechanism of the mold back to a second state with a second interval distance, and the second fastener passes through the first through-hole on the first fixture plate. (2) The first fixture plate is fixed to the mold core by a hole, and the third fastener passes through the second through hole on the second fixture plate to fix the second fixture plate to the female mold mechanism; (3) The hydraulic mechanism pulls the male mold mechanism and the female mold mechanism apart again to a third state with a third interval distance, so that the demolding mechanism carries the mold core and separates from the male mold mechanism; and (4) The hydraulic mechanism further pulls the male mold mechanism and the female mold mechanism to a fourth state with a fourth interval distance, disassembles the third fastener to remove the demolding mechanism from the mold, and after the crane is removed from the machine, disassembles the second fastener to remove the mold core from the demolding mechanism.

[0014] As a further improvement of the present invention, the male mold mechanism is provided with a first guide post, the first fixture plate is provided with a first guide sleeve, the second fixture plate is provided with a second guide post, the female mold mechanism is provided with a second guide sleeve, and step (2) further includes: the first guide post and the first guide sleeve are aligned and cooperate with each other, and the second guide post and the second guide sleeve are aligned and cooperate with each other to fit the mold disassembly mechanism into the mold.

[0015] Compared to existing technologies, this invention utilizes a first fixture plate and a second fixture plate on the demolding mechanism. Both plates have several through holes on their surfaces for fasteners to pass through. During demolding, a second fastener passes through a first through hole on the first fixture plate to fix the first fixture plate to the mold core, and a third fastener passes through a second through hole on the second fixture plate to fix the second fixture plate to the female mold mechanism. After the mold core is released from the male mold mechanism, the demolding mechanism, under the hydraulic pressure of the hydraulic system, can separate the mold core from the male mold mechanism, thus enabling quick and efficient removal of the core part of the mold for inspection, reducing disassembly, installation, and debugging time. This invention uses the mold-opening force of the injection molding machine, i.e., the hydraulic pressure of the hydraulic press, to remove the mold core, allowing for the removal of deeper and more core parts of the mold. Furthermore, the mold-opening force of the injection molding machine, i.e., the hydraulic pressure of the hydraulic press, is greater and more stable, allowing for the simultaneous removal of multiple mold cores.

Unless otherwise stated, the terms "before," "after," "upper," "lower," and similar words appearing in this invention are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" encompasses the element following "comprising" or "including" and its equivalents, but this does not preclude the element preceding "comprising" or "including" from also including other elements. In this invention, the term "several" means two or more.

[0035] Please refer to Figures 1 to 16 This invention relates to a mold-removal mechanism 100, used in conjunction with a hydraulic mechanism 200 to quickly remove a mold core 3000 from a mold 300. The mold 300 includes a male mold mechanism 3001 and a female mold mechanism 3002 that cooperate with each other. Before mold opening, the mold core 3000 is positioned on the male mold mechanism 3001. In a specific embodiment, the mold core 3000 is fixed to the male mold mechanism 3001 by a first fastener 41. In the initial open state of the male mold mechanism 3001 and the female mold mechanism 3002, the mold core 3000 is exposed on the side of the male mold mechanism 3001 facing the female mold mechanism 3002. The initial open state described here refers to the state where the mold core 3000 and the male mold mechanism 3001 have not yet separated after mold opening.

[0036] Please refer to Figures 1 to 7The demolding mechanism 100 includes a first fixture plate 11 and a second fixture plate 12. The first fixture plate 11 and the second fixture plate 12 are spaced apart and connected to each other. Both the first fixture plate 11 and the second fixture plate 12 have through holes 10 for fasteners 4 to pass through. The fasteners 4 mentioned here specifically refer to the second fastener 42 and the third fastener 43 as described below, but do not include the first fastener 41 as described above. The reason is that the first fastener 41 provides a fixed connection between the male mold mechanism 3001 and the mold core 3000, and is used to fix the mold core 3000 to the male mold mechanism 3001; the first fastener 41 does not exert force on the first fixture plate 11 and the second fixture plate 12.

[0037] Please refer to Figures 1 to 10 The demolding mechanism 100 also includes a guide mechanism 3, which can be aligned and cooperate with the corresponding structure 3' of the male mold mechanism 3001 and the female mold mechanism 3002.

[0038] Specifically, on the one hand, please refer to Figures 1 to 5 The guiding mechanism 3 includes a first guide sleeve 301. The first fixture plate 11 includes a first side 101 and a second side 102 disposed opposite to each other, the first side 101 facing the mold mechanism 3001, and the second side 102 facing the second fixture plate 12. The first guide sleeve 301 is located on the first fixture plate 11 and passes through the first side 101 and the second side 102 of the first fixture plate 11. For further details, please refer to... Figures 1 to 5 The guiding mechanism 3 includes a second guide post 302. The second fixture plate 12 includes a third side 103 and a fourth side 104 arranged opposite to each other, with the third side 103 facing the first fixture plate 11 and the fourth side 104 facing the master mold mechanism 3002. The second guide post 302 is fixed to the second fixture plate 12 and protrudes from the fourth side 104 of the second fixture plate 12. In a specific embodiment, a liner assembly consisting of four screws 3010 and a liner 3011 positions the first guide sleeve 301 on the first fixture plate 11; the second guide post 302 is fixed to the second fixture plate 12 by another screw 3020.

[0039] Please refer to Figure 9 and Figure 10 The corresponding structure 3' includes a first guide post 301' located on the male mold mechanism 3001 and a second guide sleeve 302' located on the female mold mechanism 3002. Please refer to... Figures 1 to 10The alignment and fit between the guiding mechanism 3 and the corresponding structure 3' specifically refers to the following: the first guide post 301' in the male mold mechanism 3001 extends into the first guide sleeve 301 of the first fixture plate 11 for positioning, and the second guide post 302 of the second fixture plate 12 extends into the second guide sleeve 302' of the female mold mechanism 3002 for positioning. The function of the guiding mechanism 3 is to enable the demolding mechanism 100 to fit into the mold 300 using the fit between the guide post and the guide sleeve, so as to guide the relative movement between the demolding mechanism 100 and the mold 300 during the process of hydraulic pressure provided by the hydraulic mechanism 200.

[0040] It is understood that the guide mechanism 3 in the mold-removing mechanism 100 of the present invention is configured in such a way to cooperate with the corresponding structure 3' of both the male mold mechanism 3001 and the female mold mechanism 3002; in other embodiments not shown, the guide mechanism 3 in the mold-removing mechanism 100 of the present invention is not limited to this. For example, the guide posts and guide sleeves on the male mold mechanism 3001 and the female mold mechanism 3002 of the corresponding structure 3' may interchange positions, that is, if the first guide post 301' is located on the female mold mechanism 3002, then the second guide sleeve 302' is located on the male mold mechanism 3001. This also provides guidance during the mold closing process of the male mold mechanism 3001 and the female mold mechanism 3002. Correspondingly, the guide mechanism 3 also needs to interchange positions on the first fixture plate 11 and the second fixture plate 12 of the mold disassembly mechanism 100. That is, the first guide sleeve 301 is moved to the second fixture plate 12 and passes through the third side 103 and the fourth side 104 of the second fixture plate 12 so that it can be aligned and cooperate with the first guide post 301' on the female mold mechanism 3002. In addition, the second guide post 302 is moved to be fixed to the first fixture plate 11 and exposed on the first side 101 of the first fixture plate 11 so that it can be aligned and cooperate with the second guide sleeve 302' on the male mold mechanism 3001. In summary, the guide mechanism 3 is generated in response to the corresponding structure 3' on the mold 300, and the guide mechanism 3 and the corresponding structure 3' have a one-to-one corresponding cooperation relationship.

[0041] Please refer to Figures 1 to 7 The demolding mechanism 100 also includes an elastic element 5, which is located between the first fixture plate 11 and the second fixture plate 12. One end of the elastic element 5 abuts against the first fixture plate 11 and the other end of the elastic element 5 abuts against the second fixture plate 12. The function of the elastic element 5 is to open up the first fixture plate 11 and the second fixture plate 12 to provide operating space for personnel, specifically for the installation and removal of the second fastener 42 and the third fastener 43.

[0042] Please refer to Figures 1 to 7The demolding mechanism 100 also includes a first column 6, the number of which is the same as the number of elastic elements 5, for example, four first columns 6 and four elastic elements 5. The first column 6 is positioned with the first fixture plate 11 and / or the second fixture plate 12, and the elastic element 5 is a helical spring forming a receiving space 50, into which the first column 6 extends. In a specific embodiment, the first column 6 is locked to the second fixture plate 12 by screws 60, thus elastically clamping the elastic element 5 between the first fixture plate 11 and the second fixture plate 12. In other embodiments, the first column 6 can also be locked to the first fixture plate 11 by screws 60, as long as it can provide support for the elastic element 5 between the first fixture plate 11 and the second fixture plate 12.

[0043] Please refer to Figures 1 to 7 The demolding mechanism 100 also includes a second column 7. There can be multiple second columns 7, for example, two second columns 7 per group, for a total of four groups. The four groups of second columns 7 are respectively arranged at the four corners of any plate surface. One end of the second column 7 is fixedly connected to the plate surface of one of the first fixture plate 11 and the second fixture plate 12, and the other end of the second column 7 is movably connected to the plate surface of the other of the first fixture plate 11 and the second fixture plate 12. The specific implementation of the movable connection and the fixed connection is as follows: A screw hole is formed on the right end of the second column 7. The second column 7 penetrates at least through the first fixture plate 11 from left to right, and is then fixed to the second fixture plate 12 on the right side by screws 70 locked into the screw hole. At least one of the second columns 7 has a larger radius on its left end than its right end. This left end of the second column 7 abuts against the left side of the first fixture plate 11 to prevent detachment. A portion of the left end of the second column 7 is the same size as its right end, and this portion of the left end of the second column 7 is merely confined within a hole on the surface of the first fixture plate 11. Therefore, the second column 7 can serve as a connection and guide during the relative movement between the first fixture plate 11 and the second fixture plate 12.

[0044] When the first column 6, with the elastic element 5 attached to its exterior, is relatively long and its two ends extend into the first fixture plate 11 and the second fixture plate 12 for positioning, it can also serve a guiding function. In short, the first column 6 primarily emphasizes its supporting function, and only secondarily its guiding function.

[0045] Please continue to refer to this. Figures 1 to 7 The demolding mechanism 100 also includes a lifting ring 8, which is located on the top edge of the first fixture plate 11 and the second fixture plate 12. The function of the lifting ring 8 is to facilitate the hoisting of the demolding mechanism 100 of the present invention by a crane.

[0046] The present invention also relates to a mold removal method, which uses the mold removal mechanism 100 as described above to quickly remove the mold core 3000 from the mold 300.

[0047] The mold removal method includes the following steps:

[0048] (1) The hydraulic mechanism 200 opens the male mold mechanism 3001 and the female mold mechanism 3002 of the mold 300 from the initial closed state L0 to the first state with a first spacing distance L1 (L1 > L0), removes the first fastener 41 for fixing the mold core 3000 on the male mold mechanism 3001. After the overhead crane hoists it onto the machine, the mold removal mechanism 100 is placed between the male mold mechanism 3001 and the female mold mechanism 3002.

[0049] (2) The hydraulic mechanism 200 pulls back the male mold mechanism 3001 and the female mold mechanism 3002 of the mold 300 to the second state with a second spacing distance L2 (L0 < L2 < L1). The second fastener 42 passes through the first through hole 110 on the first fixture plate 11 to fix the first fixture plate 11 and the mold core 3000, and the third fastener 43 passes through the second through hole 120 on the second fixture plate 12 to fix the second fixture plate 12 and the female mold mechanism 3002.

[0050] (3) The hydraulic mechanism 200 pulls the male mold mechanism 3001 and the female mold mechanism 3002 apart again to the third state with a third spacing distance L3 (L2 < L3 < L1), so that the mold removal mechanism 100 carries the mold core 3000 and separates from the male mold mechanism 3001; and

[0051] (4) The hydraulic mechanism 200 further enlarges the male mold mechanism 3001 and the female mold mechanism 3002 to the fourth state with a fourth spacing distance L4 (L4 ≧ L1), removes the third fastener 43 to remove the mold removal mechanism 100 from the mold 300. After the overhead crane lowers the machine, the second fastener 42 is removed to remove the mold core 3000 from the mold removal mechanism 100.

[0052] Please refer to Figures 1 to 10 , the male mold mechanism 3001 is provided with a first guide post 301', the first fixture plate 11 is provided with a first guide sleeve 301, the second fixture plate 12 is provided with a second guide post 302, and the female mold mechanism 3002 is provided with a second guide sleeve 302'. Step (2) further includes: fitting the first guide post 301' and the first guide sleeve 301 in alignment and the second guide post 302 and the second guide sleeve 302' in alignment to fit the mold removal mechanism 100 into the mold 300.

[0053] Of course, the first fastener 41, the second fastener 42 and the third fastener 43 can all be screws. Please refer to Figures 11 to 15, it should be specifically noted here that there is the following size relationship among L0, L1, L2, L3, and L4: First, L0 refers to the minimum distance value between the male mold mechanism 3001 and the female mold mechanism 3002 in the mold closing state of the mold 300. At this time, the male mold mechanism 3001 and the female mold mechanism 3002 have not been separated. Undoubtedly, L0 is the minimum value among the above five values; Next, L1 > L0. At this time, the male mold mechanism 3001 and the female mold mechanism 3002 are separated by a relatively large distance to ensure that after the overhead crane is lifted onto the machine, the mold removing mechanism 100 can be placed between the male mold mechanism 3001 and the female mold mechanism 3002; Then, L0 < L2 < L1, which ensures the tight fit between the first fixture plate 11 and the male mold mechanism 3001 and the tight fit between the second fixture plate 12 and the female mold mechanism 3002, facilitating the subsequent installation of the second fastener 42 and the third fastener 43; Then, L2 < L3 < L1, that is, after ensuring that the mold core 3000 is unlocked from the male mold mechanism 3001 and the mold removing mechanism 100 of the present invention is fixed to the female mold mechanism 3002, the mold removing mechanism 100 of the present invention can, under the hydraulic pressure of the hydraulic mechanism 200, only initially separate the mold core 3000 from the male mold mechanism 3001. However, at this time, even if the third fastener 43 is removed, the mold removing mechanism 100 cannot be removed from the mold 300 because interference will occur at the right side position of the guiding mechanism 3, such as the second guide post 302; Finally, it is necessary for the hydraulic mechanism 200 to further increase the distance between the male mold mechanism 3001 and the female mold mechanism 3002, that is, L4 ≧ L1, to ensure that the second guide post 302 is completely separated from the corresponding second guide sleeve 302', so that the mold removing mechanism 100 can be removed without obstruction.

[0054] The present invention utilizes a first fixture plate 11 and a second fixture plate 12 provided on the demolding mechanism 100. Both plates have several through holes 10 on their surfaces for the second fastener 42 and the third fastener 43 to pass through. Specifically, during the demolding process, the second fastener 42 passes through the first through hole 110 on the first fixture plate 11 to fix the first fixture plate 11 to the mold core 3000, and the third fastener 43 passes through the second through hole 120 on the second fixture plate 12 to fix the second fixture plate 12 to the female mold mechanism 3002. This releases the mold core 3000 from the male mold mechanism 3001. After the demolding mechanism 100 is fixed to the female mold mechanism 3002, the present invention, under the hydraulic pressure of the hydraulic mechanism 200, allows the demolding mechanism 100 to separate from the male mold mechanism 3001, carrying the mold core 3000 with it. This allows for the quick and efficient removal of the core part of the mold 300, the mold core 3000, for inspection, reducing the time spent on disassembly, installation, and debugging. The present invention uses the mold opening force of the injection molding machine, that is, the hydraulic pressure of the hydraulic mechanism 200, to remove the mold core 3000, which can remove the deeper and more core parts of the mold 300; the mold opening force of the injection molding machine, that is, the hydraulic pressure of the hydraulic mechanism 200, is greater and more stable, and multiple mold cores 3000 can be removed at the same time.

[0055] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of this specification should be based on those skilled in the art. For example, the directional descriptions such as "front", "back", "left", "right", "up", and "down" are important. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify or make equivalent substitutions to the present invention.
