Description

Technical Field

[0001] This utility model relates to the technical field of mold closing guide devices, and in particular to a mold closing guide device. Background Technology

[0002] Mold closing refers to the process in which the upper and lower molds move towards each other and fit together. This process usually requires the cooperation of a transmission structure to enable the molds to move towards each other. During the mold closing process, in order to prevent the upper and lower molds from shifting positions due to external vibrations or other factors, a guiding device is usually used to assist in mold closing.

[0003] In practical applications, the existing mold-closing guide devices have relatively complete structures and functions, which can meet basic usage requirements. However, the following problems still exist:

[0004] In actual use, during the mold closing process between the upper and lower molds, excessive impact force can easily cause significant wear on the contact surfaces of the upper and lower molds. At the same time, during the guiding process, the guide rod used for guiding is directly inserted into the interior of the upper mold. When the transmission distance is too large, the guide rod is prone to separating from the guide hole of the upper mold during the upward movement of the upper mold, requiring re-alignment and installation, which is very inconvenient.

[0005] Therefore, this utility model provides a mold closing guide device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a mold closing guide device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mold closing guide device, comprising an upper mold and a lower mold, wherein a disassembly and assembly buffer structure is provided between the upper mold and the lower mold, the disassembly and assembly buffer structure comprising two mounting plates, a sliding rod fixedly connected to the bottom of the upper mounting plate, a fixed cylinder slidably connected to the bottom end of the sliding rod, and the bottom of the fixed cylinder being fixedly connected to the lower mounting plate; a guide limiting structure is provided between the upper mold and the lower mold, the guide limiting structure comprising limiting rods, the number of limiting rods being two and symmetrically fixedly connected to the top of the lower mold.

[0008] In a preferred embodiment, a buffer spring is sleeved on the outer surface of the sliding rod, and the two ends of the buffer spring are fixedly connected to the mounting plate and the fixing cylinder, respectively. A rectangular clip frame is fixedly connected to one side of the mounting plate, and rectangular clip blocks are fixedly connected to both sides of the upper mold and the lower mold.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular card block and the rectangular card frame, the mounting plate can be disassembled and assembled with the upper mold and the lower mold. In this way, after the buffer spring or other components such as the sliding rod are damaged, they can be replaced in time or disassembled without affecting the disassembly and assembly between the upper mold and the lower mold.

[0010] In a preferred embodiment, a first insertion hole is provided on one side of the rectangular card block, and a second insertion hole is provided on one side of the rectangular card frame, and a threaded rod is inserted between the first insertion hole and the second insertion hole, with a fixing nut threadedly connected to one end of the threaded rod.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded insert rod, in conjunction with the first and second insert holes, the rectangular card block and the rectangular card frame are fixed, so that the rectangular card block and the rectangular card frame will not easily separate.

[0012] In a preferred embodiment, the top of the upper mold has a limiting hole, the limiting rod is inserted into the limiting hole, the top of the upper mold has a guide hole between the two limiting holes, the top of the lower mold is fixedly connected to a guide rod, the guide rod is inserted into the inner wall of the guide hole, the top of the guide rod has a threaded locking hole, the inner wall of the threaded locking hole is threaded with a threaded locking rod, and the top of the threaded locking rod is fixedly connected to a round stop block.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the guide rod and guide hole, in conjunction with the limiting rod and limiting hole, the upper mold and the lower mold can be guided during the mold closing process. At the same time, under the action of the round stop block, the limiting rod and the limiting hole, and the guide rod and the guide hole will not easily separate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a disassembly and assembly buffer structure, under the action of the sliding rod and the fixed cylinder, and in conjunction with the buffer spring, the impact force can be buffered during the mold closing process of the upper mold and the lower mold, so as to avoid excessive impact force causing wear to the upper mold and the lower mold. At the same time, under the action of the rectangular block and the rectangular frame, the mounting plate and other components can be disassembled and assembled, which facilitates the disassembly, maintenance and replacement of the buffer spring and its connecting parts. By setting up a guide and limit structure, under the action of the limit rod and the limit hole, the upper mold and the lower mold can be guided when they close. At the same time, under the action of the guide rod and the guide hole, in conjunction with the round stop block and other components, the guide rod and the limit rod will not easily separate from the guide hole and the limit hole.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, this embodiment provides a technical solution: a mold closing guide device, including an upper mold 1 and a lower mold 2, with a disassembly and assembly buffer structure 3 between the upper mold 1 and the lower mold 2. The disassembly and assembly buffer structure 3 includes two mounting plates 37. A sliding rod 38 is fixedly connected to the bottom of the upper mounting plate 37, and a fixed cylinder 39 is slidably connected to the bottom end of the sliding rod 38. The bottom of the fixed cylinder 39 is fixedly connected to the lower mounting plate 37. A guide limiting structure 4 is provided between the upper mold 1 and the lower mold 2. The guide limiting structure 4 includes two limiting rods 45, which are symmetrically fixedly connected to the top of the lower mold 2. By setting the disassembly and assembly buffer structure 3, under the action of the sliding rod 38 and the fixed cylinder 39, the mold closing guide device can... With the help of the buffer spring 310, the impact force can be buffered during the process of the upper mold 1 closing with the lower mold 2, so as to avoid excessive impact force causing wear on the upper mold 1 and the lower mold 2. At the same time, with the action of the rectangular block 31 and the rectangular frame 33, the mounting plate 37 and other components can be disassembled and assembled, which facilitates the disassembly, maintenance and replacement of the buffer spring 310 and its connecting parts. By setting the guide limit structure 4, the upper mold 1 and the lower mold 2 can be guided when they close with the limit rod 45 and the limit hole 47. At the same time, with the action of the guide rod 41 and the guide hole 46, and with the help of the round stop block 44 and other components, the guide rod 41 and the limit rod 45 will not easily separate from the guide hole 46 and the limit hole 47.

[0026] Going further, such as Figures 2-3 As shown: A buffer spring 310 is sleeved on the outer surface of the sliding rod 38. The two ends of the buffer spring 310 are fixedly connected to the mounting plate 37 and the fixing cylinder 39, respectively. A rectangular frame 33 is fixedly connected to one side of the mounting plate 37. Rectangular blocks 31 are fixedly connected to both sides of the upper mold 1 and the lower mold 2. Under the action of the rectangular blocks 31 and the rectangular frame 33, the mounting plate 37 can be disassembled from the upper mold 1 and the lower mold 2. Thus, if the buffer spring 310 is damaged or the sliding rod 38 or other parts are damaged, they can be replaced in time or disassembled without affecting the disassembly and assembly between the upper mold 1 and the lower mold 2.

[0027] The above solution also has the problem of unstable fixing between rectangular card block 31 and rectangular card frame 33, making them prone to detachment. Figure 2 and Figure 3As shown: In this solution, a first insertion hole 32 is provided on one side of the rectangular card block 31, and a second insertion hole 34 is provided on one side of the rectangular card frame 33, which is penetrated through the rectangular card frame 33. A threaded insertion rod 35 is inserted between the first insertion hole 32 and the second insertion hole 34. A fixing nut 36 is threaded to one end of the threaded insertion rod 35. Under the action of the threaded insertion rod 35, in conjunction with the first insertion hole 32 and the second insertion hole 34, the rectangular card block 31 and the rectangular card frame 33 are fixed, so that the rectangular card block 31 and the rectangular card frame 33 will not easily separate.

[0028] The above solutions also have the problem that when the mold closing distance is large, the limiting rod 45 and guide rod 41 are prone to separating from the limiting hole 47 and guide hole 46, such as... Figure 2 and Figure 4 As shown, the top of the upper mold 1 has a limiting hole 47, and the limiting rod 45 is inserted into the limiting hole 47. The top of the upper mold 1 has a guide hole 46 located between the two limiting holes 47. The top of the lower mold 2 is fixedly connected to a guide rod 41, which is inserted into the inner wall of the guide hole 46. The top of the guide rod 41 has a threaded locking hole 42, and the inner wall of the threaded locking hole 42 is threadedly connected to a threaded locking rod 43. The top of the threaded locking rod 43 is fixedly connected to a round stop 44. Under the action of the guide rod 41 and the guide hole 46, and in conjunction with the limiting rod 45 and the limiting hole 47, the upper mold 1 and the lower mold 2 can be guided during the mold closing process. At the same time, under the action of the round stop 44, the limiting rod 45 and the limiting hole 47, and the guide rod 41 and the guide hole 46 will not easily separate.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] In use, the rectangular card block 31 is snapped into the rectangular card frame 33, the threaded rod 35 is fixed to the first insertion hole 32 and the second insertion hole 34, and the fixing nut 36 is fixed to the threaded rod 35, thereby fixing the rectangular card block 31 and the rectangular card frame 33.

[0032] At this time, the limiting rod 45 is inserted into the limiting hole 47 for guidance, the guide rod 41 is inserted into the guide hole 46 for guidance, and the threaded clamp rod 43 is fixed into the threaded clamp hole 42. Then the round stop block 44 can be installed. Then, during the guidance process, the sliding rod 38 can slide on the inner wall of the fixed cylinder 39, which can be buffered in conjunction with the buffer spring 310. At the same time, the limiting rod 45 can be guided in conjunction with the limiting hole 47, and the guide rod 41 can be guided on the inner wall of the guide hole 46.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
