Description

Technical Field

[0001] This application belongs to the field of manufacturing technology, specifically relating to a mold protector and a mold assembly. Background Technology

[0002] As an important molding equipment in the manufacturing industry for injection-molded products, a mold consists of a second mold plate and a first mold plate. The second mold plate moves relative to the first mold plate. When the second mold plate moves closer to the first mold plate, the mold closing process is achieved; when the second mold plate moves away from the first mold plate, the mold opening process is achieved. However, during the mold opening process, if the second mold plate does not open smoothly to the appropriate position, it will affect the product removal process, and the mold is also more susceptible to collisions and damage. Utility Model Content

[0003] The purpose of this application is to provide a mold protector and mold assembly that can solve the problem of molds being easily bumped and damaged in related technologies.

[0004] In a first aspect, embodiments of this application provide a mold protector, including a magnetic base, a linkage assembly, a universal joint, and a detection element. The linkage assembly is disposed on the magnetic base and includes at least two connecting rods connected in sequence, wherein at least two of the connecting rods are connected through the universal joint. The detection element is provided at one end of the linkage assembly away from the magnetic base, and the detection element is used to detect the opening and closing state of the mold.

[0005] Secondly, embodiments of this application also provide a mold assembly, including the mold protector described above.

[0006] In this embodiment, the mold protector supports the detection element using a magnetic base and a connecting rod assembly. The relative position of two connecting rods can be adjusted via a universal joint, thereby adjusting the position of the detection element relative to the magnetic base. This ensures the detection element is aligned with the mold, facilitating accurate detection of the mold's presence and thus providing feedback on whether the mold is in place, improving detection accuracy. Furthermore, accurate mold placement detection allows operators to perform operations even when the mold is not in place, preventing it from interfering with subsequent product removal and avoiding collisions or damage to the mold.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The mold protector and mold assembly provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0024] Please refer to Figures 1-5 The mold protector 10 disclosed in this application is used to protect the mold. The mold includes a first template S1 and a second template S2. The first template S1 and the second template S2 are a fixed mold and a moving mold, respectively. The first template S1 and the second template S2 can move relative to each other. When the first template S1 and the second template S2 are in contact, it indicates that the mold is in the closed state. When the first template S1 and the second template S2 are separated, it indicates that the mold is in the open state.

[0025] The mold protector 10 includes a magnetic base 100, a connecting rod assembly 200, a universal joint 300, and a detection element 400. The magnetic base 100 is used to magnetically attach to the mold so that the position of the mold protector 10 is fixed. Optionally, the magnetic base 100 can be attached to the first template S1 in the mold, the second template S2 in the mold, or the injection molding machine S. The connecting rod assembly 200 is used to connect the magnetic base 100 and the detection element 400. The universal joint 300 is used to connect two adjacent connecting rods 210 in the connecting rod assembly 200.

[0026] A linkage assembly 200 is disposed on the magnetic base 100. The linkage assembly 200 includes at least two sequentially connected connecting rods 210, and at least two of the connecting rods 210 are connected by a universal joint 300. Optionally, the connecting rods 210 and the magnetic base 100 can be fixedly connected by welding, bonding, or bolting. The linkage assembly 200 may include two, three, or other numbers of connecting rods 210. This embodiment does not limit the number of connecting rods 210. The connecting rods 210 and the universal joint 300 can also be connected by welding, bonding, or bolting. Thus, the relative position of two of the connecting rods 210 can be adjusted through the universal joint 300.

[0027] Optionally, there may be one universal joint 300, through which two adjacent connecting rods 210 are connected; or there may be multiple universal joints 300, through which any two adjacent connecting rods 210 can be connected.

[0028] A detection element 400 is provided at the end of the connecting rod assembly 200 away from the magnetic base 100. The detection element 400 is used to detect the opening and closing state of the mold. Optionally, the detection element 400 can be a proximity sensor, which detects the presence or absence of the mold and then provides feedback on the opening and closing state of the mold. Specifically, when the mold protector 10 is set on the first template S1, the proximity sensor detects the presence or absence of the second template S2; when the mold protector 10 is set on the second template S2, the proximity sensor detects the presence or absence of the first template S1. Of course, the detection element 400 can also be a photoelectric sensor or other detection element 400 that can provide feedback on the opening and closing state of the mold.

[0029] In this embodiment, the mold protector 10 supports the detection element 400 via the magnetic base 100 and the connecting rod assembly 200. The relative positions of two connecting rods 210 can be adjusted via the universal joint 300, thereby adjusting the position of the detection element 400 relative to the magnetic base 100. This ensures the detection element 400 is aligned with the mold detection, facilitating accurate detection of the mold's presence or absence and providing feedback on whether the mold is in place, thus improving detection accuracy. Furthermore, accurate mold placement detection by the detection element 400 allows operators to perform operations even when the mold is not in place, preventing the out-of-place mold from affecting subsequent product removal and avoiding collisions and damage to the out-of-place mold.

[0030] In one optional embodiment, the end of the linkage 200 away from the magnetic base 100 can be directly fixed to the detection element 400 by means of welding, bonding or bolting.

[0031] In another embodiment, the mold protector 10 further includes an adjustment structure, wherein one end of the linkage 200 away from the magnetic base 100 is connected to the detection element 400 through the adjustment structure to adjust the position of the detection element 400 relative to the linkage 200.

[0032] Optionally, the adjustment structure may include a first connecting block and a second connecting block. The first connecting block is connected to the detection element 400, and the second connecting block is connected to the connecting rod 210. The first and second connecting blocks are rotatably connected. By adjusting the relative positions of the first and second connecting blocks, the position of the detection element 400 relative to the connecting rod assembly 200 can be adjusted. The first connecting block and the detection element 400 can be connected by welding, bonding, or bolting, and the second connecting block and the connecting rod 210 can be connected by welding, bonding, or bolting. The first and second connecting blocks can be rotatably connected via a rotating shaft. Of course, the adjustment structure can also be other structures, as long as it can adjust the position of the detection element 400 relative to the connecting rod assembly 200.

[0033] In this embodiment, the mold protector 10 is equipped with an adjustment structure. The user can adjust the position of the detection element 400 relative to the connecting rod assembly 200 as needed, so that the position of the detection element 400 is more suitable for detecting the opening and closing state of the mold, which helps to improve the detection accuracy.

[0034] In a further embodiment, reference is made to... Figure 1As shown, there are at least two universal joints 300, including a first universal joint 310 and a second universal joint 320, wherein at least two connecting rods 210 are connected through the first universal joint 310, and the second universal joint 320 serves as an adjustment structure. Optionally, the structures of the first universal joint 310 and the second universal joint 320 may be the same or different.

[0035] In this embodiment, the second universal joint 320 serves as an adjustment structure. The position of the detection element 400 relative to the connecting rod assembly 200 can be adjusted in all directions through the second universal joint 320. This helps to expand the adjustable range of the detection element 400, making the position of the detection element 400 more suitable for detecting the opening and closing state of the mold, and further improving the detection accuracy of the detection element 400.

[0036] Of course, in other embodiments, the end of the linkage 200 away from the magnetic base 100 can be connected to the detection element 400 via a structure other than the universal joint 300.

[0037] In one alternative embodiment, there is one first universal joint 310, through which two connecting rods 210 are connected.

[0038] In another embodiment, the number of first universal joints 310 is at least two, and any two adjacent connecting rods 210 are connected by the first universal joints 310.

[0039] In this embodiment, the number of first universal joints 310 is increased, which can adjust the relative position of any two adjacent connecting rods 210, thereby adjusting the position of the detection element 400. Therefore, the range of motion of the detection element 400 is further increased, which is more conducive to adjusting the position of the detection element 400, making the position of the detection element 400 more suitable for detecting the opening and closing state of the mold, which is conducive to further improving the detection accuracy of the detection element 400.

[0040] In one optional embodiment, the universal joint 300 and the connecting rod 210 can be connected by a non-removable method such as welding or bonding. Optionally, the first universal joint 310 is connected to the connecting rod 210 to it by a non-removable method such as welding or bonding; the second universal joint 320 and the connecting rod 210, and the second universal joint 320 and the detection element 400 can also be connected by a non-removable method such as welding or bonding.

[0041] In another embodiment, the universal joint 300 is detachably connected to the connecting rod 210.

[0042] Optionally, the first universal joint 310 is connected to the connecting rod 210 connected to it by means of snap-fit, bolt connection or other means, and the second universal joint 320 is also connected to the connecting rod 210 and the detection element 400 by means of snap-fit, bolt connection or other means.

[0043] Alternatively, one of the first universal joint 310 and the connecting rod 210 may have a connecting hole, and the other may have a threaded hole. Fasteners such as screws and bolts are used to connect the first universal joint 310 and the connecting rod 210 by passing through the connecting hole and extending into the threaded hole. By loosening the fasteners, the fasteners are disengaged from the threaded hole and the connecting hole, thereby separating the first universal joint 310 and the connecting rod 210, and achieving disassembly of the first universal joint 310. This structure can also be used between the second universal joint 320 and the connecting rod 210, and between the second universal joint 320 and the detection element 400, to achieve disassembly of the second universal joint 320.

[0044] Using this embodiment, the user can install and disassemble the universal joint 300 as needed, which facilitates the replacement and maintenance of the universal joint 300, ensures the smooth adjustment of the position of the detection element 400, and also allows for the convenient storage of the mold protector 10 by disassembling the universal joint 300 when the mold protector 10 is not in use.

[0045] In a further embodiment, the universal joint 300 is provided with a slot, and the connecting rod 210 is engaged in the slot. Optionally, the shape of the slot is the same as the shape of the cross-section of the connecting rod 210. More preferably, the connecting rod 210 is a square rod and the slot is a square groove, or the connecting rod 210 is a round rod and the slot is a round groove. The part with the slot can be made of plastic or other structures that can produce slight deformation to ensure that the connecting rod 210 is smoothly engaged in the slot.

[0046] In this embodiment, the connecting rod 210 is directly snapped into the slot to install the universal joint 300. The connecting rod 210 can be directly disengaged from the slot to disassemble the universal joint 300. The installation and disassembly process of the universal joint 300 is simplified, making it easier to install and disassemble the universal joint 300.

[0047] In this application, the magnetic base 100 has opposing magnetic surfaces 100a and mounting surfaces 100b. The connecting rod 210 is connected to the mounting surface 100b and is perpendicular to it. Optionally, the magnetic base 100 can be a cubic structure or other structures. This application does not limit the specific structure of the magnetic base 100. The magnetic surface 100a and the mounting surface 100b can be parallel, or they can intersect but not be parallel. The connecting rod 210 and the mounting surface 100b can be fixedly connected by welding, bonding, or bolting.

[0048] In this embodiment, the connecting rod 210 is perpendicular to the mounting surface 100b, that is, the connecting rod 210 is vertically arranged relative to the mounting surface 100b. Therefore, the other end of the connecting rod 210 is relatively far away from the mounting surface 100b. Other connecting rods 210 and the detection element 400 can be arranged at positions relatively far away from the mounting surface 100b, which helps to expand the adjustable range of the detection element 400 and facilitates the adjustment of the position of the detection element 400. This avoids the situation where other connecting rods 210 are too close to the mounting surface 100b, which would limit the adjustable range of the detection element 400 due to the mold connected to the magnetic base 100.

[0049] Of course, in other embodiments, the magnetic surface 100a and the mounting surface 100b may not be arranged opposite each other. Optionally, the magnetic surface 100a and the mounting surface 100b may be directly connected; the connecting rod 210 may intersect with the mounting surface 100b but not be perpendicular to it.

[0050] In an optional embodiment, refer to Figure 1 As shown, the mold protector 10 also includes a magnetic switch 500, which is disposed on the magnetic base 100 and located between the mounting surface 100b and the magnetic surface 100a. The magnetic switch 500 is used to control the magnetic state of the magnetic base 100.

[0051] Optionally, an energized coil can be installed inside the magnetic base 100. The magnetic control switch 500 is used to control the energization and de-energization of the energized coil. When the magnetic control switch 500 controls the energized coil to be energized, the magnetic base 100 generates a magnetic field. The magnetic field generates a magnetic attraction force on the external mold or injection molding machine S, fixing the magnetic base 100 to the mold or injection molding machine S. When the magnetic control switch 500 controls the energized coil to be de-energized, the magnetic field generated by the magnetic base 100 disappears, and the magnetic base 100 does not generate a magnetic attraction force. At this time, the magnetic base 100 can be detached from the mold or injection molding machine S.

[0052] In this embodiment, the mold protector 10 is equipped with a magnetic switch 500. Therefore, there is no need to manually overcome the magnetic force generated by the magnetic base 100. The magnetic force generated by the magnetic base 100 is not limited by human intervention; it can be greater, making it easier to install the magnetic base 100 in different positions and improving the installation stability of the mold protector 10. Furthermore, the magnetic switch 500 is located between the mounting surface 100b and the magnetic surface 100a, which does not affect the installation of the connecting rod 210 or the magnetic base 100's attachment to external equipment, facilitating operator control of the magnetic switch 500.

[0053] Of course, in other embodiments, the mold protector 10 may not be equipped with a magnetic switch 500, and the magnetic base 100 may use a permanent magnet, that is, the magnetic base 100 may be in a magnetic state.

[0054] In an optional embodiment, refer to Figure 1 As shown, the mold protector 10 also includes a signal line 600. The first end of the signal line 600 is connected to the detection element 400, and the second end is used to connect to the injection molding machine S. Optionally, the signal line 600 can be an electrical connection line. Thus, the detection element 400 and the external injection molding machine S are connected via the signal line 600, allowing the external injection molding machine S to control the driving components that move the second mold plate S2 based on the information detected by the detection element 400.

[0055] In this embodiment, the mold protector 10 is further equipped with a signal line 600 to realize the communication connection between the detection element 400 and the external injection molding machine S. This is beneficial for the injection molding machine S to automatically control the driving component that drives the second template S2 according to the detection element 400. It is also beneficial to control the mold in time when it is not in place, effectively avoiding the impact of the mold on the subsequent product removal process. At the same time, it effectively avoids the mold being collided and damaged when it is not in place.

[0056] Based on the mold protector 10 disclosed in this application, embodiments of this application also disclose a mold assembly, which includes the mold protector 10 described above.

[0057] Optionally, the mold assembly also includes a mold, and the magnetic base 100 of the mold protector 10 can be disposed on the mold, specifically, see reference. Figures 2-4 As shown, the mold includes a first template S1 and a second template S2, and the magnetic base 100 can be disposed on either the first template S1 or the second template S2; or, refer to Figure 5 As shown, the mold is usually installed on the injection molding machine S. The position of the injection molding machine S is fixed. The magnetic base 100 of the mold protector 10 can be set on the injection molding machine S. In short, the installation position of the magnetic base 100 is not limited. The magnetic base 100 can be fixed relative to the first template S1 or the second template S2 of the mold.

[0058] In this embodiment, the mold protector 10 of the mold assembly adopts a special structure. It relies on the magnetic base 100 and the connecting rod group 200 to support the detection element 400. By adjusting the universal joint 300, the relative position of two connecting rods 210 can be adjusted, thereby adjusting the position of the detection element 400 relative to the magnetic base 100. This makes the detection element 400 face the mold detection, which is conducive to the accurate detection of the presence or absence of the mold, thereby providing feedback on whether the mold is in place. This is beneficial for the staff to operate when the mold is not in place, avoiding the impact of the incomplete mold on the subsequent product removal process, and also avoiding collisions and damage to the incomplete mold.

[0059] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
