TECHNICAL FIELD
[0001] The utility model relates to the mold guide pillar guide bushing with heat dissipation function. BACKGROUND
[0002] The mold guide bushing is a guide part in a mold, which is used to ensure that the movable mold plate and the fixed mold plate can be accurately aligned and move along a straight line during mold opening and closing, and prevent the mold parts from being deflected or worn.
[0003] During a long working process, the guide bushing will generate friction heat due to the relative movement with the guide pillar. If the heat cannot be effectively dissipated, the material of the guide bushing may be expanded due to heat, thereby affecting the precision and the fitting clearance, and ultimately affecting the guiding performance of the mold and the quality of the molded product. In addition, the lubricant (such as oil or grease) between the guide bushing and the guide pillar is very sensitive to temperature changes. An excessively high temperature may cause the lubricant to fail or lose, resulting in dry friction and increased wear.

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0028] As Figures 1-7The utility model discloses a mould guide pillar guide bush with heat dissipation function, including guide bush body 1 and guide pillar 2, the guide bush body 1 includes the cooperation sleeve 11 of guide pillar 2 and is located the support sleeve 12 below cooperation sleeve 11, and the guide bush is generally installed on the fixed mold plate of mould, and the corresponding guide pillar 2 is installed on the movable mold plate, when the mould is closed, the guide pillar 2 will slide into the cooperation sleeve 11 of guide bush, and the relative position accuracy between the upper and lower mold plate is guaranteed by the clearance fit of guide pillar 2 and guide bush, thereby ensuring the quality stability of the quality of the product (this is prior art, here do not make specific elaboration), still including a plurality of inside contact convex strip 3 with condensate and the cover 4 of detachable connection with each contact convex strip 3 through bolt mode, cooperation sleeve 11 is hollow cylinder setting, each contact convex strip 3 is along the circumferential spacing arrangement of cooperation sleeve 11 and is fixedly connected with cooperation sleeve 11, the support sleeve 12 is detachably installed with protective cover 5 through buckle, bolt mode, each cover 4 downward projection all fall on protective cover 5, because the guide bush body 1 circumferential setting has a plurality of contact convex strip 3 with condensate, so after each guide pillar 2 is respectively inserted into the corresponding guide bush body 1, the circumferential of each guide pillar 2 can contact each contact convex strip 3 at this moment and the temperature of condensate can be transferred to each contact convex strip 3 and then to each guide pillar 2 to realize the cooling of each guide pillar 2, that is, heat dissipation, and because of the existence of each contact convex strip 3, the guide pillar 2 loaded into the guide bush body 1 is difficult to rotate compared with the guide bush body 1 and can be stably installed together, 2, and because each cover 4 is detachably connected with contact convex strip 3, condensate is not easy to be contaminated and can stably play performance under the action of no external force, and if condensate fails, then after each cover 4 is detached from contact convex strip 3, the condensate can be poured out for treatment, and then new condensate is loaded, 3, because protective cover 5 is located on the support sleeve 12 and the downward projection of each cover 4 all fall on protective cover 5, so the user will not directly contact each cover 4 under the action of no external force, and will not randomly disassemble the cover 4.
[0029] Among them, the guide pillar 2 is provided with a contact groove 21 corresponding to each contact convex strip 3, each contact convex strip 3 is a semicylinder with an outward opening, and because each contact convex strip 3 is a semicylinder with an outward opening, the contact between the contact convex strip 3 and the guide pillar 2 is linear contact rather than surface contact, which can reduce the friction resistance between the two to some extent, facilitate smooth movement of the guide pillar 2, and the outer side of each contact convex strip 3 can stably fit with the cooperation sleeve 11 of the guide bush body 1 to complete fixation. The design of the semicylinder can increase the contact area between the condensate and the guide pillar 2. Compared with planar contact, the curved surface can better fit the surface of the guide pillar 2 to ensure more uniform heat distribution.
[0030] The guide sleeve body 1 is provided with a plurality of air holes 13 between the adjacent contact protrusions 3, and the air holes 13 are arranged in the up-down direction. The air holes 13 between the guide sleeve body 1 and the contact protrusions 3 facilitate air circulation, further enhance the cooling effect, and enable the external air to enter the guide sleeve body 1 and the guide column 2 to achieve heat dissipation of the guide column 2 and the guide sleeve body 1, thereby further improving the heat dissipation effect between the guide column 2 and the guide sleeve body 1.
[0031] Preferably, each air hole 13 is arranged in a flared manner from the inside to the outside. Since the outer diameter of each air hole 13 is the largest and the inner diameter is the smallest, the external air can quickly enter between the guide sleeve body 1 and the guide column 2.
[0032] In addition, the support sleeve 12 is provided with a positioning plug 121 made of rubber or other materials that can easily deform in the circumferential direction. Each positioning plug 121 includes a plug-in section 1211 and a limiting section 1212 below the plug-in section 1211. The protective cover 5 is provided with a positioning slot 121 corresponding to each positioning plug 121. Each plug-in section 1211 is located in the corresponding positioning slot 121, and each limiting section 1212 is located below the corresponding positioning slot 121 and abuts the support sleeve 12. After the protective cover 5 is placed in the support sleeve 12, each positioning plug 121 on the support sleeve 12 can be inserted into the corresponding positioning slot 121 on the protective cover 5. At this time, the limiting section 1212 at the bottom of each positioning plug 121 will first enter the corresponding positioning slot 121, and each limiting section 1212 will forcibly pass through the corresponding positioning slot 121. At this time, each limiting section 1212 is located below the corresponding positioning slot 121 and abuts the support sleeve 12. At this time, each plug-in section 1211 is located in the corresponding positioning slot 121. Therefore, without external force, each limiting section 1212 cannot pass through the corresponding positioning slot 121, and each positioning plug 121 can be stably positioned in the positioning slot. Therefore, the protective cover 5 cannot be separated from the support sleeve 12 and can cover each cover body 4, so that each cover body 4 cannot be directly contacted and can be stably positioned on the corresponding contact protrusion 3 without external force.
[0033] Each limiting section 1212 is arranged in a triangular prism with the top angle facing down. When the protective cover 5 is installed on the support sleeve 12, the bottom of each limiting section 1212, i.e., the top corner position, of each positioning plug 121 on the protective cover 5 is first inserted into the positioning slot 121. At this time, the bottom of each limiting section 1212 can be more smoothly aligned with the positioning slot 121, thereby exerting a downward force on the positioning slot 121 and forcibly passing through the corresponding positioning slot 121. At this time, each limiting section 1212 is located below the corresponding positioning slot 121 and abuts the support sleeve 12.
[0034] Each of the limiting sections 1212 is provided with a matching groove 12121 along the front and back direction, and the presence of each matching groove 12121 can effectively reduce the thickness of each limiting section 1212, so that when each limiting section 1212 needs to forcibly pass through the corresponding positioning slot 121, each limiting section 1212 can more smoothly deform to pass through the corresponding positioning slot 121, and complete the cooperation of each positioning plug 121 and the corresponding positioning slot.
[0035] The above description of disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
