Description

Technical Field

[0001] This utility model relates to a guide sleeve disassembly and assembly structure for a mold, and more specifically, it relates to a guide sleeve disassembly and assembly structure for a mold. Background Technology

[0002] The guide bushing assembly / disassembly structure mainly involves the fit between the guide bushing and the guide pillar, as well as the installation and disassembly methods of the guide bushing in the mold. The guide bushing and guide pillar together form the guiding device of the mold, used to ensure the relative positional accuracy of the moving mold and the fixed mold during mold opening and closing.

[0003] The guide bushings of existing molds are prone to wear after long-term use. The overall structure of the mold makes the connection between the guide bushing and other parts of the mold too tight or complicated, which requires the disassembly of a large number of other parts when replacing a single guide bushing, increasing the difficulty of replacement.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a guide sleeve disassembly and assembly structure for molds. By using screws and threaded holes to fix the blocking ring and the limiting ring, the guide sleeve is fixed. At the same time, rotating the positioning bolt contacts and fixes the blocking ring, improving the fixing effect of the guide sleeve. The operation process is simple, and it can easily and quickly replace a single worn guide sleeve, reducing the difficulty of replacement.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a guide sleeve disassembly and assembly structure for a mold, including a base, a lower mold provided at the upper end of the base, an upper mold provided above the lower mold, and a guide post fixedly installed at each of the four corners of the upper end of the base. The upper mold is characterized by: a limiting groove being provided at each of the four corners of the upper end, a limiting ring being fixedly installed in the limiting groove, a guide sleeve being movably inserted and connected within the limiting groove and the limiting ring, a blocking ring being fixedly installed at the upper end of the guide sleeve, two positioning bolts being movably inserted and connected to the left and right ends of the upper mold, the positioning bolts being movably inserted and abutting against the blocking ring, and the guide post being movably inserted within the guide sleeve.

[0007] The present invention is further configured such that the blocking ring and the limiting ring are in contact.

[0008] The present invention is further configured such that two threaded holes are provided at the upper ends of both the blocking ring and the limiting ring.

[0009] The present invention is further configured such that the upper mold and the base maintain a parallel positional relationship.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. When replacing a worn guide sleeve, insert the new guide sleeve into the limiting ring of the limiting groove. At this time, the blocking ring and the limiting ring are in contact, so that the upper part of the guide sleeve will not leave the limiting groove. The axis of the threaded holes of the limiting ring and the blocking ring coincides. The blocking ring and the limiting ring are fixed by screws in the threaded holes, thus completing the fixation of the guide sleeve. At the same time, rotating the positioning bolt contacts and fixes the blocking ring, improving the fixation effect of the guide sleeve. The operation process is simple and can easily and quickly complete the replacement of a single worn guide sleeve, reducing the difficulty of replacement. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A guide sleeve assembly / disassembly structure for a mold, such as Figures 1 to 3 As shown, the system includes a base 1, a lower mold 2 at the upper end of the base 1, and an upper mold 3 above the lower mold 2. The upper mold 3 and the base 1 are parallel to each other. A guide post 4 is fixedly installed at each of the four corners of the upper end of the base 1. A limiting groove 5 is opened at each of the four corners of the upper end of the upper mold 3. A limiting ring 6 is fixedly installed in the limiting groove 5. A guide sleeve 7 is movably inserted and connected to the limiting groove 5 and the limiting ring 6. A blocking ring 8 is fixedly installed at the upper end of the guide sleeve 7. The blocking ring 8 is in contact with the limiting ring 6. Two positioning bolts 9 are movably inserted and connected to the left and right ends of the upper mold 3. The positioning bolts 9 movably insert and abut against the blocking ring 8. The guide posts 4 are movable. Inserted within the guide sleeve 7, when a single guide sleeve 7 is worn and needs replacement, the new guide sleeve 7 is inserted into the limiting ring 6 of the limiting groove 5. At this time, the blocking ring 8 contacts the limiting ring 6, so that the upper part of the guide sleeve 7 will not leave the limiting groove 5. The axis between the threaded holes 10 of the limiting ring 6 and the blocking ring 8 coincides. The blocking ring 8 and the limiting ring 6 are fixed by screws engaging the threaded holes 10, thereby completing the fixation of the guide sleeve 7. At the same time, rotating the positioning bolt 9 contacts and fixes the blocking ring 8, improving the fixation effect of the guide sleeve 7. The operation process is simple and can easily and quickly complete the replacement of a single worn guide sleeve 7, reducing the difficulty of replacement.

[0021] like Figure 3 As shown, both the blocking ring 8 and the limiting ring 6 have two threaded holes 10 at their upper ends.

[0022] Working principle: When a single guide sleeve 7 is worn and needs to be replaced, the new guide sleeve 7 is inserted into the limiting ring 6 of the limiting groove 5. At this time, the blocking ring 8 contacts the limiting ring 6, so that the upper part of the guide sleeve 7 will not leave the limiting groove 5. The axis between the threaded holes 10 of the limiting ring 6 and the blocking ring 8 coincides. The blocking ring 8 and the limiting ring 6 are fixed by screws in the threaded holes 10, thereby completing the fixation of the guide sleeve 7. At the same time, rotating the positioning bolt 9 contacts and fixes the blocking ring 8, improving the fixation effect of the guide sleeve 7. The operation process is simple and can easily and quickly complete the replacement of a single worn guide sleeve 7, reducing the difficulty of replacement.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
