Description

Technical Field

[0001] This invention relates to the field of mechanical design, and in particular to an automated mold-opening device. Background Technology

[0002] Mold processing is a common type of processing that is widely used in various fields. Among them, footwear products, such as shoe soles or insoles, are often obtained through mold processing.

[0003] Currently, most shoe product molds rely on manual mold opening and closing, although some use automated mold opening devices to ensure reliability. However, common mold opening and closing devices do not offer high reliability in fixing the mold, and shoe product molds often require shaking operations to ensure uniform material processing. Therefore, the reliability requirements for both the shoe product mold and the mold opening and closing device are relatively high.

[0004] On the other hand, as the reliability of shoe molds fixed on the mold opening device is improved, the difficulty of disassembling them on the mold opening device usually increases, which takes more time and affects the efficiency of shoe mold replacement or maintenance. Moreover, when replacing or maintaining shoe molds on the mold opening and closing device, it is often necessary to stop the mold opening and closing device for adjustment, which seriously affects the processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an automated mold opening device that can solve one or more of the above-mentioned problems.

[0006] According to one aspect of the present invention, an automated mold opening device is provided, comprising a mold opening and closing mechanism, a fixed template, a mold locking mechanism, a fixed plate mechanism, a mounting base, a connecting block, and a clamping component. The mold opening and closing mechanism, the fixed plate mechanism, and the mold locking mechanism are all mounted on the mounting base. The fixed plate mechanism can fix the fixed template to the mounting base. The fixed template is used to load the mold. The connecting block and the clamping component are both mounted on the mold. The mold opening and closing mechanism can drive the connecting block to move. The mold locking mechanism can engage with the clamping component.

[0007] The beneficial effects of this invention are as follows: By incorporating a fixing plate mechanism and a mold-locking mechanism, the mold and mold template can be effectively fixed to the mounting base, ensuring the reliability of their fixation. Furthermore, the mold-opening and closing mechanism facilitates easy mold opening and closing, resulting in a high degree of automation. Since the fixing and releasing of the mold and mold template from the mounting base can be directly achieved through the fixing plate mechanism and the mold-locking mechanism, the difficulty of disassembling the mold and mold template is reduced, facilitating replacement or maintenance, and effectively avoiding downtime, thus significantly improving production efficiency. On the other hand, the connecting block and clamping parts are designed as independent mold accessories, allowing them to be installed on any mold for compatibility without requiring custom mold design, reducing costs and mold design complexity.

[0008] In some embodiments, the mold opening and closing mechanism includes a first cylinder and a swing arm. The first cylinder includes a first cylinder body and a first piston rod. The first cylinder body is rotatably mounted on a mounting base, and the first piston rod is hinged to the swing arm. One end of the swing arm is hinged to the mounting base. Thus, the first cylinder can drive the swing arm to swing to a certain extent, thereby realizing the mold opening and closing action.

[0009] In some embodiments, the rocker arm is provided with a limiting hole, the limiting hole having an opening, and the connecting block can pass through the opening and be disposed within the limiting hole. The opening facilitates the connecting block's entry into or exit from the limiting hole, thereby achieving the connection between the connecting block and the rocker arm. The limiting hole also limits the movement of the connecting block to ensure the opening and closing of the mold.

[0010] In some embodiments, the mold-locking mechanism includes a second cylinder and a rocker arm. The second cylinder includes a second cylinder body and a second piston rod. The second cylinder body is fixedly mounted on a mounting base, and the second piston rod is connected to the rocker arm. One end of the rocker arm is hinged to the mounting base, and the rocker arm is provided with a latch, into which a locking element can be engaged. Thus, the second cylinder can drive the rocker arm to swing, allowing the rocker arm to engage the locking element, thereby fixing the mold and preventing erroneous movement of the mold during mold opening and closing, which would affect the mold opening and closing process.

[0011] In some embodiments, the fixing mechanism includes a third cylinder and a first insert block. A first hole is provided on one side of the fixing template. The third cylinder includes a third cylinder body and a third piston rod. The third cylinder body is fixedly mounted on a mounting base, and the third piston rod is connected to the first insert block, which can be inserted into the first hole. Thus, the third cylinder can drive the first insert block to move, and by providing the first hole on the fixing template, when the first insert block is inserted into the first hole, one side of the fixing template can be restricted by the third cylinder.

[0012] In some embodiments, the fixing plate mechanism includes a guide post and a slider. The guide post is mounted on a mounting base, and the slider is slidably fitted onto the guide post. The slider is connected to a third piston rod, and the first insert is mounted on the slider. Thus, the first insert can be connected to the third piston rod via the slider, and the guide post guides the movement of the slider, improving the accuracy of the third piston rod's movement and ensuring that the first insert can be effectively inserted into the first hole.

[0013] In some embodiments, the mounting base has a protrusion with a second insert block, and the other side of the fixing template has a second hole into which the second insert block can be inserted. When the second insert block is inserted into the second hole, the other side of the fixing template is restricted by the protrusion on the mounting base, thereby restricting both sides of the fixing template to achieve the fixation of the lifting plate.

[0014] In some embodiments, the present invention further includes a height adjustment plate disposed between the fixed template and the mold. When the mold needs to be replaced, the thickness of the mold to be replaced may not be the same due to the different products being manufactured, such as high heels and flat shoes. By setting up the height adjustment plate, when replacing molds of different thicknesses, height adjustment plates of different thicknesses can be replaced accordingly, so that the total thickness of the height adjustment plate and the mold before replacement is the same as the total thickness of the height adjustment plate and the mold after replacement. Maintaining the total height eliminates the need for additional adjustments to the usage adaptation height of other mechanisms when replacing the mold, thereby effectively avoiding downtime and ensuring processing efficiency.

[0015] In some embodiments, the present invention further includes a swaying mold mechanism connected to the mounting base and driving the mounting base to oscillate. The swaying mold mechanism can oscillate the mold located on the mounting base by oscillating it, thereby shaking the mold during the mold closing process to improve the uniformity of the raw materials in the mold and thus improve the quality of the finished product.

[0016] In some embodiments, the mold-shaking mechanism includes a fourth cylinder and a base. The fourth cylinder includes a fourth cylinder body and a fourth piston rod. The fourth cylinder body is hinged to the base, and the mounting seat is hinged to the base. The mounting seat is provided with a connecting shaft, and the fourth piston rod is hinged to the connecting shaft. Because the mounting seat is hinged to the base, when the mounting seat is moved by the fourth cylinder, it is restricted by the base, allowing it to swing around its connection position on the base to achieve mold shaking.

[0026] There are two mold opening and closing mechanisms 1. The mold opening and closing mechanism 1 includes a first cylinder 11 and a rocker arm 12. The first cylinder 11 includes a first cylinder body 111 and a first piston rod 112. One end of the first piston rod 112 is movably installed in the first cylinder body 111 by a piston. The mounting base 5 is provided with a first cylinder body seat. The first cylinder body 111 is rotatably installed on the first cylinder body seat of the mounting base 5 by a pin. The other end of the first piston rod 112 is hinged to the rocker arm 12 by a pin. One end of the rocker arm 12 is hinged to the mounting base 5 by a pin. The rocker arm 12 is also provided with a long strip-shaped limiting hole 121. The limiting hole 121 has an opening 122, which is connected to the outside.

[0027] There are two locking mechanisms 3. The locking mechanism 3 includes a second cylinder 31 and a rocker arm 32. The second cylinder 31 includes a second cylinder body 311 and a second piston rod 312. The second cylinder body 311 is fixedly mounted on the mounting base 5 by bolts. One end of the second piston rod 312 is movably mounted in the second cylinder body 311 by a piston. The other end of the second piston rod 312 is connected to a clamping block. The clamping block is hinged to the rocker arm 32 by a pin, so that the second piston rod 312 is connected to the rocker arm 32. One end of the rocker arm 32 is hinged to the mounting base 5 by a shaft, and the other end of the rocker arm 32 is provided with a buckle 321.

[0028] The plate fixing mechanism 4 includes a third cylinder 41, a first insert block 42, a guide post 43, and a slider 44. The third cylinder 41 includes a third cylinder body 411 and a third piston rod 412. One end of the third piston rod 412 is movably mounted in the third cylinder body 411 via a piston. The guide post 43 is fixedly mounted on the mounting base 5 by bolts. The slider 44 is slidably sleeved on the guide post 43, and the other end of the slider 44 is fixedly connected to the third piston rod 412 by bolts. There are multiple first insert blocks 42, and all first insert blocks 42 are fixedly mounted on the slider 44 by snap-fit, that is, the third piston rod 412 is connected to the first insert block 42 through the slider 44.

[0029] The front side of the fixed template 2 is provided with a first hole 21. The number of first holes 21 is the same as the number of first inserts 42, and the shape and size of the first holes 21 match the shape and size of the first inserts 42. When needed, multiple first inserts 42 can be inserted into multiple first holes 21 one by one.

[0030] The mounting base 5 is also provided with a protrusion 51, and a second insert 511 is provided on the protrusion 51. There are multiple second inserts 511. The rear side of the fixed template 2 is provided with a second hole 22. The number of second holes 22 is the same as the number of second inserts 511, and the shape and size of the second holes 22 match the shape and size of the second inserts 511. When needed, multiple second inserts 511 can be inserted into multiple second holes 22 one by one.

[0031] The top of the fixed template 2 can be used to load the mold 10. The automated mold opening device of the present invention also includes a height adjustment plate 101, which is disposed between the fixed template 2 and the mold 10. The height adjustment plate 101 and the mold 10 are matched and the total thickness of each set of height adjustment plate 101 and mold 10 is the same.

[0032] Furthermore, the fixed template 2 is also provided with mounting holes 23, which can facilitate the fixing of the mold 10 or the height adjustment plate 101 on it, so as to further improve the installation reliability of the mold 10 or the height adjustment plate 101 on the fixed template 2.

[0033] This automated mold opening device also includes retaining rings 8. There can be multiple retaining rings 8. In this embodiment, four retaining rings 8 are preferred. All four retaining rings 8 are fixedly installed on the side of the fixed template 2 by bolts. Two retaining rings 8 are located on one side of the mounting base 5, and the other two retaining rings 8 are located on the other side of the mounting base 5. The setting of retaining rings 8 can facilitate the connection of external traction mechanisms such as robotic arms. When the fixed template 2 is not fixed, it can be easily moved by the traction mechanism.

[0034] There are two connecting blocks 6, which are fixedly installed on both sides of the upper mold of the mold 10 by bolts. There are also two clamping parts 7, which are fixedly installed on the front side of the mold 10 by bolts.

[0035] The size of the connecting block 6 matches the size of the opening 122, so that when needed, the two connecting blocks 6 can pass through the two openings 122 of the two mold opening and closing mechanisms 1 respectively, and are respectively set in the two limiting holes 121, so that the two connecting blocks 6 can be connected to the swing arms 12 of the two mold opening and closing mechanisms 1 respectively, so that the two mold opening and closing mechanisms 1 can drive the two connecting blocks 6 to move respectively.

[0036] The position of the locking piece 7 matches the position of the buckle 321 on the two locking mechanisms 3, so that when needed, the two locking pieces 7 can be respectively locked into the buckle 321 of the two locking mechanisms 3, so that the two locking pieces 7 and the two locking mechanisms 3 are respectively locked together.

[0037] This automated mold opening device also includes a mold-shaking mechanism 9, which includes a fourth cylinder 91 and a base 92. The fourth cylinder 91 includes a fourth cylinder body 911 and a fourth piston rod. The fourth cylinder body 911 is hinged to the base 92 via a shaft. One end of the fourth piston rod is movably mounted inside the fourth cylinder body 911 via a piston. The bottom of the mounting base 5 is provided with a hole, in which a connecting shaft 912 is provided. The other end of the fourth piston rod is hinged to the connecting shaft 912. A part of the mounting base 5 is also hinged to the base 92 via a shaft. The base 92 is also provided with a base plate, which facilitates the placement of the base 92 on a horizontal surface.

[0038] When this automated mold opening device is in use, the fixed template 2 can be placed on the mounting base 5, the height adjustment plate 101 can be fixed to the fixed template 2 by bolts, and the mold 10 can be fixed to the height adjustment plate 101 or the fixed template 2 by bolts, so that the height adjustment plate 101 is located between the fixed template 2 and the mold 10. When the third cylinder 41 of the fixing plate mechanism 4 is activated, the third cylinder 41 can drive the slider 44 to move along the guide post 43, so that the multiple first inserts 42 on the slider 44 can be inserted one by one into the multiple first holes 21 of the fixing template 2, thus connecting the fixing template 2 and the slider 44. The third cylinder 41 can continue to drive the slider 44 to move, and the fixing template 2 connected to the slider 44 moves accordingly, until the multiple second inserts 511 on the protrusion 51 are inserted one by one into the multiple second holes 22 on the fixing template 22. Then the protrusion 51 blocks the forward movement of the fixing template 2. At this time, while the third cylinder 41 maintains power, the fixing template 2 is fixed by the third cylinder 41 and the protrusion 51. Thus, the fixing plate mechanism 4 can fix the fixing template 2 on the mounting base 5.

[0039] Then, the second cylinder 31 is activated, which drives the rocker arm 32 to swing, so that the two clips 7 on the mold 10 can be respectively engaged in the latches 321 of the two rocker arms 32. Then, while the second cylinder 31 maintains power, the two clips are respectively fixed by the two rocker arms 32, so that the mold 10 is fixed by the mold locking mechanism 3.

[0040] Then, the swing arm 12 is swung so that the two connecting blocks 6 on the mold 10 can pass through the two openings 122 on the two swing arms 12 and be embedded into the limiting hole 21, thereby realizing the separate connection of the two connecting blocks 6 with the swing arms 12 of the two mold opening and closing mechanisms 1.

[0041] When the mold 10 needs to be opened, the first cylinder 11 can be activated, causing the first piston rod 112 of the first cylinder 11 to extend, which causes the swing arm 12 to swing. The swing of the swing arm 12 can drive the connecting block 6 to move, and as the connecting block 6 moves, the upper mold of the mold 10 can separate from the lower mold, thus realizing the mold opening.

[0042] When the mold 10 needs to be closed, the first cylinder 11 can be activated, causing the first piston rod 112 of the first cylinder 11 to retract, causing the swing arm 12 to swing. The swing of the swing arm 12 can drive the connecting block 6 to move, and as the connecting block 6 moves, the upper mold of the mold 10 can close with the lower mold to achieve mold closing.

[0043] In addition, if it is necessary to shake the mold 10 during the mold closing process, the fourth cylinder 91 can be activated. The fourth cylinder 91 can drive the mounting seat 5 to move. Since part of the mounting seat 5 is hinged on the base, the mounting seat 5 can swing around the axis connected to the base 92. Since the fixed template 2 is restricted on the mounting seat 5, the swing of the mounting seat 5 can drive the fixed template 2 to swing. At the same time, the mold 10 located on the fixed template 2 and fixed to the mold locking mechanism 3 can also swing with the swing of the fixed template 2 to realize the shaking action.

[0044] In this automated mold opening device, the opening, closing, and rocking actions of the mold 10 can all be automated, achieving a high degree of automation.

[0045] When the present invention requires replacement of mold 10, the fourth cylinder 91 can first adjust the fixed template 2 to a horizontal position. Then, the connection between the fourth cylinder 91 and the fixed template 2 can be released, and the first cylinder 11 can be activated to make the swing arm 12 swing until the opening 122 on the swing arm 12 can approach the connecting block 6. By swinging the swing arm 12, the connecting block 6 can pass through the opening 122, thus making the connecting block 6 disengage from the limiting hole 121, thereby separating the mold 10 from the mold opening and closing mechanism 1. At the same time, the second cylinder 31 is activated, which can drive the rocker arm 32 to swing, thereby making the clamping piece 7 disengage from the buckle 321, that is, the mold 10 is no longer fixed by the mold locking mechanism 3.

[0046] The third cylinder 41 is also activated, which drives the slider 44 to move along the guide post 43, so that the multiple first inserts 42 located on the slider 44 can disengage one by one from the multiple first holes 21 of the fixed template 2, that is, the fixed template 2 is no longer under force and is fixed. At this time, the fixed template 2 and the second insert 511 can be separated, and the fixed template 2, the mold 10 and the height adjustment plate 101 can be removed from the mounting base 5 together.

[0047] Afterwards, select the appropriate height adjustment plate according to the required mold height to make the total thickness of the new mold and the new height adjustment plate the same as the total thickness of the mold 10 and the height adjustment plate 101 before replacement. Then, install the connecting block 6 and the clamping piece 7 on the new mold, and the new mold, the height adjustment plate and the fixed template 2 can be reinstalled back into the automatic mold opening device.

[0048] In this automated mold opening device, since the total thickness of the height adjustment plate 101 and the mold 10 is the same before and after replacement, the installation positions of the mold opening and closing mechanism 1, the mold locking mechanism 3, the fixing plate mechanism 4, the fixing plate 2 and the mold shaking mechanism 9 are the same. The height of each of the above mechanisms does not need to be changed. Therefore, the replacement and maintenance of the mold 10 by this automated mold opening device does not require readjustment of the above mechanisms, which can effectively avoid downtime and effectively ensure processing efficiency.

[0049] On the other hand, since the connecting block 6 and the clip 7 are set independently of the mold 10, they can be used to adapt to any mold by being installed on the mold 10, without the need for special mold customization, thus reducing costs and mold design difficulty.

[0050] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
