Technical Field

[0001] The utility model relates to the technical field of medical molds, in particular to an oil-free guiding mechanism for medical molds. Background Art

[0002] At present, the existing medical molds usually use standard guide pins and guide sleeves as the guide mechanism. The guide mechanism composed of the standard guide pins and the standard guide sleeves needs to add lubricating oil as a lubricant to reduce the friction between the standard guide pins and the standard guide sleeves, reduce the wear rate of the standard guide pins, and finally extend the use of the guide mechanism. The utility model relates to the field of medical mold technology. With the development of society, the medical mold industry is becoming more and more developed, and medical molds are constantly being improved to meet the needs of production. Most medical molds have the function of producing product molding, but the function of preventing the product from being contaminated by oil is not yet complete. Due to the particularity of the use of medical device products, the safety requirements of the products are extremely high. The existing guide mechanism needs to add lubricating oil as a lubricant, which causes the medical device products to be contaminated by oil molecules, resulting in scrapping and inability to be used, which makes it inconvenient to prevent the product from being contaminated by oil. Utility Model Content

[0003] In order to overcome the problem that medical molds have extremely high safety requirements for products due to the special uses of medical devices during use, the existing guide mechanism needs to add lubricating oil as a lubricant, causing the medical device products to be contaminated by oil molecules, resulting in them being scrapped and unusable, making it inconvenient to prevent the products from being contaminated by oil.

[0004] The technical solution of the utility model is: an oil-free guiding mechanism for a medical mold, comprising an upper mold base, a lower mold base, an auxiliary component, a guiding component, a positioning component and a buffer component; a lower mold base is arranged below the upper mold base, a buffer component with a buffer function is arranged below the lower mold base, an auxiliary component is provided inside the upper mold base, a guiding component with a guiding function is arranged inside the auxiliary component, and a positioning component with a positioning function is arranged above the lower mold base.

[0005] Preferably, when the upper mold base performs up and down reciprocating motion, the upper mold base can perform reciprocating motion through the guide assembly. Since the sliding friction between the guide assemblies is small, there is no need to add lubricating oil, so oil-free production can be achieved, thereby preventing the product from being contaminated by oil. Moreover, when the mold vibrates during operation, the rebound force generated by the elastic deformation of multiple groups of buffer assemblies can achieve a buffering protection effect for the mold.

[0006] Preferably, the auxiliary component includes an injection hole and a mounting hole; an injection hole is opened inside the upper mold base, and a mounting hole is opened inside the upper mold base, and multiple groups of mounting holes are opened; the material can be added through the injection hole, and the guide component can be installed and fixed through multiple groups of mounting holes.

[0007] Preferably, the guide assembly includes a guide ring and an installation groove; a guide ring is arranged inside the installation hole, and an installation groove is opened on the inner wall of the guide ring, and multiple groups of installation grooves are opened; the guide assembly can be accommodated and installed by the multiple groups of installation grooves, and the guide ring can play the role of sliding guide.

[0008] Preferably, the guide assembly also includes a rotating shaft, rotating balls, a guide column and a guide groove; a rotating shaft is arranged inside the mounting groove, and multiple groups of rotating shafts are arranged, both ends of the rotating shaft are rotatably connected to the inner wall of the mounting groove, rotating balls are arranged on the side walls of the rotating shaft, and a guide column is arranged above the lower mold seat, and the guide column is arranged inside the mounting hole, and a guide groove is opened on the side wall of the guide column, and the rotating balls are slidably connected to the guide column through the guide groove; when the upper mold seat reciprocates up and down, the upper mold seat can drive multiple groups of guide rings to move up and down, and the guide rings can drive multiple groups of rotating balls to reciprocate through the guide grooves. Since the sliding friction between the guide column and the rotating balls is small, there is no need to add lubricating oil, so oil-free production can be achieved, thereby preventing the product from being contaminated by oil.

[0009] Preferably, the positioning assembly includes a mounting block and a positioning block; a mounting block is arranged above the lower die base, two groups of mounting blocks are arranged, and a positioning block is arranged above the mounting block; when the upper die base descends and fits with the lower die base, the positioning groove below the upper die base will fit with the positioning block, and the positioning block makes the upper die base more accurately positioned during the stamping process of the mold, and the product production will not be unqualified due to extrusion and collision.

[0010] Preferably, the buffer assembly includes a fixed base plate and a fixed groove; a fixed base plate is arranged below the lower mold base, a fixed groove is opened inside the fixed base plate, and the upper mold base is arranged above the fixed base plate; through the setting of the fixed base plate and the fixed groove, the mold can be supported and fixed.

[0011] Preferably, the buffer assembly includes a buffer spring and a buffer cylinder; a buffer cylinder is arranged inside the fixed groove, and multiple groups of buffer cylinders are arranged, and a buffer spring is arranged inside the buffer cylinder, and one end of the buffer spring is fixedly connected to the bottom of the upper mold base; when the mold vibrates during operation, the rebound force generated by the elastic deformation of the multiple groups of buffer springs can achieve a buffering protection effect on the mold.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional medical molds, due to the special use of medical device products, the safety requirements of the products are extremely high. The existing guide mechanism needs to add lubricating oil as a lubricant, which causes the medical device products to be contaminated by oil molecules, resulting in scrapping and unusability, making it inconvenient to prevent the products from being contaminated by oil. The medical mold is provided with an auxiliary structure and a guide structure. When the upper mold base reciprocates up and down, the upper mold base can reciprocate through the guide structure. Since the sliding friction between the guide structures is small, there is no need to add lubricating oil, so oil-free production can be achieved, thereby preventing the product from being contaminated by oil;

[0014] 2. When the upper die seat reciprocates up and down, the upper die seat can drive multiple sets of guide rings to move up and down, and the guide rings can drive multiple sets of rotating balls to reciprocate through the guide grooves. Since the sliding friction between the guide column and the rotating ball is small, there is no need to add lubricating oil, so oil-free production can be achieved, thereby preventing the product from being contaminated by oil. In addition, when the mold vibrates during operation, the rebound force generated by the elastic deformation of multiple sets of buffer springs can achieve a buffering protection effect on the mold;

[0015] 3. When the upper die seat descends and fits with the lower die seat, the positioning groove under the upper die seat will fit with the positioning block. The positioning block makes the upper die seat more accurately positioned during the stamping process of the mold, and will not cause the product to be unqualified due to extrusion and collision, thereby achieving the effect of precise positioning.
