Description

Technical Field

[0001] The invention relates to a mold frame structure, in particular to a mold frame structure and a side cylinder disassembly process thereof. Background Art

[0002] The mold frame is an important part of the mold. As a structure that supports and fixes other components of the mold, it ensures the stability and precision of the mold during the production process, and further ensures the dimensional accuracy and surface quality of the product. In the existing mold frame structure, side cylinders are usually fixedly installed on both sides of the mold frame to drive the upper mold plate to rise and fall relative to the lower mold plate. However, in actual use, the side cylinders that have been running for a long time often have the following problems: 1. Damage to the buffer device; 2. Oil leakage or unstable output; 3. Oil leakage between the piston axis and the guide sleeve; 4. Damage caused by operational or environmental factors; 5. Damage caused by improper maintenance; 6. Design or installation problems, etc.; These problems not only affect the production efficiency of the mold, but may also cause damage to the mold itself and unnecessary maintenance costs, reducing the stability and precision of production. Therefore, it is necessary to regularly maintain and replace the side cylinders. Ordinary side cylinders are generally fixedly connected to the mold frame. When disassembling and replacing them, it is not only time-consuming and labor-intensive, but also inconvenient to observe and repair the mold; Summary of the Invention

[0003] The purpose of the present invention is to provide a mold frame structure and its side cylinder disassembly process, aiming to solve the problem of inconvenience in disassembling and maintaining the side cylinder in the prior art, and to ensure that when the side cylinder is disassembled for maintenance, the mold can also be observed and repaired at the same time.

[0004] The present invention provides the following technical solutions:

[0005] The cam is driven by the side cylinders to move relative to the top mold and the bottom mold to press the top mold and the bottom mold together to form a workpiece in the aligned cavity. Two guide groups are arranged on the outside of the two side cylinder groups. A base 1, a guide rail 1, a guide rail 2 and a base 2 are arranged on the lower mold in sequence. The base 1 and the base 2 are respectively used to be fixedly connected to the two guide groups. The guide rail 1 and the guide rail 2 are distributed in parallel along the horizontal plane and are respectively slidably installed with the slide 1 and the slide 2 at the bottom of the two side cylinder groups. The driving tops of the two side cylinder groups are The cam is fixed to the upper template via a first slide rail and a second slide rail, one end of the upper template is hingedly mounted with a hinge plate, and the other end is vertically fixed with a guide plate, the hinge plate performs vertical guiding movement along the guide groove of a guide group, when the hinge plate moves to the top end of the guide groove, it is limited by the end block, and at the same time, the guide plate also slides out of the guide groove of the other guide group and disengages from the guide groove, the two ends of the side cylinder group close to the hinge plate are also hingedly mounted with the slide table and the first slide rail respectively, when the hinge plate moves to the top end of the guide groove, one group of side cylinder groups slides away from between the upper template and the lower template, and the other group of side cylinder groups is used to drive the upper template to drive the upper mold to rotate around the hinge end of the hinge plate;

[0006] At this point, the disassembly of the two side cylinder groups on the mold frame can be done as follows: first, the two side cylinder groups drive the upper mold plate to move to the top, and then the side cylinder group away from the hinged plate side can directly slide away from between the upper mold plate and the lower mold plate along the second guide rail, and then continue to drive the side cylinder group close to the hinged plate side to move, which can drive the upper mold plate to drive the upper mold mold to rotate around the hinged end of the hinged plate. At this time, an opening mode is formed between the upper mold plate and the lower mold plate, and personnel can easily inspect and maintain the opened upper mold mold and the lower mold mold separately, and at the same time, the opened upper mold plate For support and positioning, as for the structure used to support and position the upper template, it will not be elaborated here. It can be a support rod extending into the side of the upper template. The support rod is attached to the side of the upper template, so that the upper template can use the hinge end of the hinge plate as the support end to position the hinge plate. Then, the side cylinder group close to the hinge plate can also slide away from between the upper template and the lower template along the guide rail like the side cylinder group away from the hinge plate. At this time, the two groups of side cylinder groups can be quickly disassembled and maintained, and the installation of a new side cylinder group can be reversed by the above operation, which is more convenient.

[0007] Preferably, the two side cylinder groups have the same structure, and each side cylinder group has two side cylinder bodies, and the four side cylinder bodies are distributed in a rectangular shape. Since the two side cylinder groups have the same structure, that is, both ends of the two side cylinder groups are hinged, there is no need to follow the reverse operation of the disassembly operation during installation. That is, the side cylinder group at one end away from the hinged plate can be installed first. At this time, the side cylinder body of the side cylinder group can be extended a specific distance for installation at both ends, which is more convenient.

[0008] Preferably, the slide 1 and the slide 2 are provided with a docking groove 1 for the mounting end of the side cylinder body, and the slide rail 1 and the slide rail 2 are provided with a docking groove 2 for the driving end of the side cylinder body, and four groups of parallel articulated shafts pass through the side cylinder bodies in the docking groove 1 and the docking groove 2 to form the articulated ends of the side cylinder bodies, and the axial extension direction of the articulated shafts is also the same as the sliding direction of the slide 1, the slide 2, the slide rail 1 and the slide rail 2, and the ends of each group of articulated shafts are also locked and installed on the two ends of the corresponding slide 1, the slide 2, the slide rail 1 and the slide rail 2 by two groups of locking nuts; at this point, the articulated installation of the two groups of side cylinder groups can be achieved by only four groups of articulated shafts, and when disassembly is required, only the articulated shafts need to be removed, which is more convenient.

[0009] Preferably, a pressing spring group is provided in the guide groove for pressing the corresponding hinge plate or guide plate, and the pressing heights of the pressing spring groups in the two groups of guide grooves are the same, thereby ensuring that the driving force of the pressing can be balanced as much as possible.

[0010] Preferably, one end of the upper template is overlapped on the slot of the hinge plate, and both sides of the end of the upper template are installed in the slot through a pin shaft. The end of the upper template is also provided with an arc surface that always fits against the bottom of the slot during rotation. That is, when the upper template rotates around the top of the hinge plate, in addition to the support provided by the pin shaft, the abutment between the arc surface and the slot can also provide rotation support for the upper template, thereby improving the stability of the rotation of the upper template.

[0011] Preferably, a driving motor is also installed on the lower template, and a driving wheel is installed on the driving end of the driving motor. The sides of slide 1 and slide 2 are arranged with straight racks that mesh with the driving wheels for transmission. Therefore, the side cylinder group can be driven to slide away from between the upper template and the lower template by the power of the driving motor, and the degree of automation is better.

[0012] Preferably, an arc-shaped groove surface is further provided on the docking groove one and the docking groove two, and the mounting end and the driving end of the side cylinder body are provided with a raised arc configured in the arc-shaped groove surface, and the curvature of the arc-shaped groove surface is less than 30°. Because the side cylinder body has a small swing amplitude when the upper template is rotated by the top pressure drive, the support of the arc-shaped groove surface is provided, and the line support is changed to the surface support. Not only can the stability of the support be improved, but also the curvature is smaller, and the swing amplitude of the side cylinder body is also smaller, so it will not form a restriction on the swing amplitude of the side cylinder body.

[0013] Preferably, the upper template and the lower template are also provided with detachable plug-in baffles with limited positions at both ends of slide 1, slide 2, slide rail 1 and slide rail 2, so as to limit the ends of slide 1, slide 2, slide rail 1 and slide rail 2 that slide into place, so as to improve the overall stability.

[0014] A side cylinder disassembly process of a mold frame structure, based on the above mold frame structure, includes the following steps:

[0015] First, the two groups of side cylinders lift the upper template to the top. At this time, the hinge plate is limited to the top of the guide groove, and the guide plate is separated from the guide groove. Then, the side cylinder group away from the hinge plate side slides along the guide rail 2 between the upper template and the lower template, and then continues to start the movement of the side cylinder body in the side cylinder group close to the hinge plate side, so that the upper template drives the upper mold to rotate around the hinge end of the hinge plate. At this time, an opening mode is formed between the upper template and the lower template; when the side cylinder group drives the upper template to rotate 90° and abut against the platform on one side, the horizontal insert plate on the platform extends into the slot of the guide plate to vertically position the upper template, and then, the side cylinder group is pushed along the guide rail 1 to slide away from between the upper template and the lower template, and the complete disassembly of the two groups of side cylinder groups can be completed.

[0016] The beneficial effects of the present invention are:

[0017] The present invention provides a mold frame structure and a side cylinder disassembly process thereof, aiming to solve the problem of inconvenience in disassembling and maintaining the side cylinders in the prior art. A new mold frame structure and a disassembly process of the side cylinders thereon are adopted to ensure that when the side cylinders are disassembled for maintenance, the mold can also be observed and repaired at the same time. When the two groups of side cylinder groups on the mold frame are disassembled, the two groups of side cylinder groups first drive the upper template to move to the top, and then the side cylinder group away from the hinged plate side can directly slide away from between the upper template and the lower template along the second guide rail, and then continue to drive the side cylinder group close to the hinged plate side to move, so that the upper template can be driven to drive the upper mold to rotate around the hinged end of the hinged plate. At this time, the upper template and the lower template An opening mode is formed between them, and personnel can easily inspect and maintain the opened upper mold and lower mold separately, and support and position the opened upper mold at the same time. As for the structure used to support and position the upper mold, it will not be elaborated here. It can be a support rod extending into the side of the upper mold. The support rod is attached to the side of the upper mold, so that the upper mold can be positioned with the hinge end of the hinge plate as the support end to position the hinge plate. Then, the side cylinder group close to the hinge plate can also slide away from between the upper mold and the lower mold along the guide rail like the side cylinder group away from the hinge plate. At this time, the two groups of side cylinder groups can be quickly disassembled and maintained, and the installation of the new side cylinder group can be reversed by the above operation, which is more convenient.

DETAILED DESCRIPTION

[0028] Example 1

[0029] like Figure 1As shown, a mold frame structure, in this embodiment, includes an upper mold plate 1 for installing an upper mold 2 and a lower mold plate 3 for installing a lower mold 4. The upper mold plate 1 and the lower mold plate 3 move relative to each other under the drive of the side cylinder groups 5 on both sides to drive the upper mold 2 and the lower mold 4 to be pressed relative to each other to form the workpiece in the aligned cavity. Two groups of guide groups 6 are also arranged on the outside of the two groups of side cylinder groups 5. Base 1 7, guide rail 1 8, guide rail 2 9 and base 2 10 are arranged on the lower mold plate 3 in sequence. Base 1 7 and base 2 10 are respectively used to be fixedly connected with the two groups of guide groups 6. Guide rail 1 8 and guide rail 2 9 are distributed parallel to the horizontal plane and are slidably installed with slide 1 11 and slide 2 12 at the bottom of the two groups of side cylinder groups 5 respectively. The driving tops of the two groups of side cylinder groups 5 are also connected by slide rail 1 13 and the second slide rail 14 are slidably installed on the upper template 1. One end of the upper template 1 is hingedly installed with a hinge plate 15, and the other end is vertically fixed with a guide plate 16. The hinge plate 15 performs vertical guiding movement along the guide groove 17 of a group of guide groups 6. When the hinge plate 15 moves to the top of the guide groove 17, it is limited by the end block, and at the same time, the guide plate 16 also slides out of the guide groove 17 of the other group of guide groups 6 and disengages from the guide groove 17. The two ends of the side cylinder group 5 near the side of the hinge plate 15 are also hingedly installed with the slide 11 and the slide rail 13 respectively. When the hinge plate 15 moves to the top of the guide groove 17, one group of side cylinder groups 5 slides away from between the upper template 1 and the lower template 3, and the other group of side cylinder groups 5 is used to drive the upper template 1 to drive the upper mold 2 to rotate around the hinged end of the hinge plate 15;

[0030] At this point, the disassembly of the two groups of side cylinder groups 5 on the mold frame can be as follows: first, the two groups of side cylinder groups 5 drive the upper mold plate 1 to move to the top, and then the side cylinder group 5 away from the side of the hinged plate 15 can directly slide along the guide rail 2 9 away from between the upper mold plate 1 and the lower mold plate 3, and then continue to drive the side cylinder group 5 close to the side of the hinged plate 15 to move, so that the upper mold plate 1 can be driven to drive the upper mold 2 to rotate around the hinged end of the hinged plate 15. At this time, an opening mode is formed between the upper mold plate 1 and the lower mold plate 3, and personnel can easily inspect and maintain the opened upper mold 2 and the lower mold 4 separately, and at the same time, the opened upper mold The plate 1 is supported and positioned. As for the structure for supporting and positioning the upper template 1, it will not be elaborated here. It can be a support rod extending into the side of the upper template 1. The support rod is attached to the side of the upper template 1, so that the upper template 1 can use the hinge end of the hinge plate 15 as the support end to position the hinge plate 15. Then, the side cylinder group 5 close to the hinge plate 15 can also slide away from between the upper template 1 and the lower template 3 along the guide rail 8 like the side cylinder group 5 away from the hinge plate 15. At this time, the two groups of side cylinder groups 5 can be quickly disassembled and maintained, and the installation of a new side cylinder group 5 can be reversed by the above operation, which is more convenient.

[0031] Example 2

[0032] like Figure 2-6As shown, a mold frame structure, in this embodiment, is further limited based on Example 1, that is, the structures of the two groups of side cylinder groups 5 are set to be the same, and each group of side cylinder groups 5 has two groups of side cylinder bodies 18, and the four groups of side cylinder bodies 18 are distributed in a rectangular shape. Since the structures of the two groups of side cylinder groups 5 are the same, that is, both ends of the two groups of side cylinder groups 5 are hinged, there is no need to follow the reverse operation of the disassembly operation during installation, that is, the side cylinder group 5 at one end away from the hinged plate 15 can also be installed first. At this time, the side cylinder body 18 of the side cylinder group 5 can be extended to a specific distance for installation at both ends, which is also more convenient.

[0033] A docking groove 19 is provided on slide 11 and slide 2 12 for the installation end of the side cylinder body 18 to be placed, and a docking groove 2 20 is provided on slide rail 13 and slide rail 2 14 for the driving end of the side cylinder body 18 to be placed, and four groups of parallelly distributed hinge shafts 21 pass through the side cylinder body 18 in the docking groove 19 and the docking groove 2 20 to form the hinge end of the side cylinder body 18, and the axial extension direction of the hinge shaft 21 is also the same as the sliding direction of slide 11, slide 2 12, slide rail 1 13 and slide rail 2 14, and the end of each group of hinge shafts 21 is also locked and installed on the two ends of the corresponding slide 11, slide 2 12, slide rail 1 13 and slide rail 2 14 by two groups of locking nuts 22; at this point, the hinged installation of the two groups of side cylinder groups 5 can be achieved by only four groups of hinge shafts 21, and when disassembly is required, only the hinge shaft 21 needs to be removed, which is more convenient.

[0034] A pressing spring group 23 is provided in the guide groove 17 for pressing the corresponding hinge plate 15 or guide plate 16, and the pressing heights of the pressing spring groups 23 in the two groups of guide grooves 17 are the same to ensure that the driving force of the pressing can be balanced as much as possible.

[0035] One end of the upper template 1 is overlapped on the slot of the hinge plate 15, and the two sides of the end of the upper template 1 are connected and installed in the slot through the pin shaft 24. The end of the upper template 1 is also provided with an arc surface 25 that always fits against the bottom of the slot during rotation. That is, when the upper template 1 rotates around the top of the hinge plate 15, in addition to the support provided by the pin shaft 24, the abutment between the arc surface 25 and the slot can also provide rotation support for the upper template 1, thereby improving the stability of the rotation of the upper template 1.

[0036] A drive motor 26 is also installed on the lower template 3, and a drive wheel 27 is installed on the drive end of the drive motor 26. A straight rack 28 that engages with the drive wheel 27 is arranged on the side of the slide 11 and the slide 2 12. Therefore, the power of the drive motor 26 can be used to drive the side cylinder group 5 to slide away from between the upper template 1 and the lower template 3, and the degree of automation is better.

[0037] The upper template 1 and the lower template 3 are also provided with detachable plug-in baffles 30 with limited positions at both ends of slide 11, slide 2 12, slide rail 13 and slide rail 2 14, so as to limit the ends of slide 11, slide 2 12, slide rail 13 and slide rail 2 14 that slide into place, so as to improve the overall stability.

[0038] Example 3

[0039] like Figure 7 As shown, a mold frame structure, in this embodiment, is further limited based on Example 2, and the difference from Example 2 is that an arc-shaped groove surface 29 is further provided on the docking groove 19 and the docking groove 2 20, and the mounting end and the driving end of the side cylinder body 18 are provided with a convex arc arranged in the arc-shaped groove surface 29, and the curvature of the arc-shaped groove surface 29 is less than 30°. Because the side cylinder body 18 has a small swing amplitude when the upper template 1 is rotated by the top pressure driving, the support of the arc-shaped groove surface 29 is provided, and the line support is changed to the surface support, which not only improves the stability of the support, but also the curvature is smaller. At the same time, the swing amplitude of the side cylinder body 18 is also smaller, so it will not form a restriction on the swing amplitude of the side cylinder body 18.

[0040] Example 4

[0041] A side cylinder disassembly process of a mold frame structure, based on the above mold frame structure, includes the following steps:

[0042] When the upper mold 1 is lifted and the lower mold 3 is lifted, the upper mold 1 is rotated and the lower mold 3 is opened, and the upper mold 1 is opened and the lower mold 3 is opened.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
