Meanwhile, all technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Referring to fig. 1-3, the invention provides an automatic compensation high-precision guide pillar and guide sleeve. The injection mold can be applied to the injection mold, and the injection mold can be used for producing the sealing ring. The existing sealing ring injection mold generally comprises a plurality of product cavities, so that a plurality of sealing rings can be formed in one injection molding process; meanwhile, in order to take out products conveniently, the existing mold is required not to be completely closed when the mold is closed, and a mold closing gap of 0.03-0.08 mm needs to be reserved between an upper mold and a lower mold to be used as a parting surface interlayer. Therefore, after the product is formed, a thin connecting piece is arranged between the sealing rings, so that when the product is taken out, all the sealing rings can be mutually drawn out in a string manner, all the products are taken out in one time, and then the connecting piece is peeled off from the product. In order to improve the molding quality of a product, the upper die and the lower die need to be ensured to be accurate in position when the die is closed, so that the die needs to be positioned by using the guide pillar guide sleeve, but in the traditional guide pillar guide sleeve, the relative position of the guide pillar is invariable, so that the die cannot meet the production requirement when the die is closed.
Therefore, the invention provides the guide pillar and guide sleeve with automatic compensation and high precision. The guide column and guide sleeve structure comprises a guide column 100 and a guide sleeve (not shown), wherein the guide column and guide sleeve are matched products, the guide column 100 comprises a cylindrical mounting part 110 and a cylindrical column body 120, a vertically through cavity 111 is arranged in the mounting part 110, the cavity 111 comprises an upper cavity 112 and a lower cavity 113, the inner diameter of the upper cavity 112 is smaller than that of the lower cavity, the upper cavity 112 and the lower cavity 113 are circular cavities, and the central lines of the upper cavity 112 and the lower cavity 113 are overlapped. A clamping groove 114 is formed between the upper cavity 112 and the lower cavity 113; in addition, a sealing groove 115 is arranged in the middle of the upper cavity 112, and the cross section of the sealing groove 115 is rectangular; an internal thread 116 is provided at the lower end of the lower cavity 113.
The cylinder 120 comprises a tapered section 121, a straight section 122 and a snap ring 123 from top to bottom in sequence, the tapered section 121 is small at the top and big at the bottom, the outer diameter of the straight section 122 is equivalent to that of the lowest end of the tapered section 121, and the outer diameter of the snap ring 123 is larger than that of the straight section 122. In addition, the outer diameter of the straight section 122 is slightly smaller than the inner diameter of the upper cavity 112, and the difference between the two is about 0.002 mm-0.003 mm; and the outer diameter of the snap ring 123 is greater than the inner diameter of the upper cavity 112 and less than the inner diameter of the lower cavity 113. The cylinder 120 is formed by cutting a solid steel rod through a lathe. Because the conical section 121 and the straight section 122 can be formed by one-time clamping processing, the conical section and the straight section have good coaxiality.
When the die is used, the conical section 121 is used for ensuring the coaxiality of the guide pillar and the guide sleeve, so that the die assembly of the fixed die and the movable die is more accurate; then utilize straight body segment to make and have good degree of agreeing with between guide pillar and the guide pin bushing, avoid guide pillar guide pin bushing to appear rocking in work.
In addition, the guide sleeve 100 of the embodiment further includes an adjusting nut 130 and two leaf springs 140, the adjusting nut 130 includes an external thread, the middle of the adjusting nut 130 further includes a screwdriver slot, and the external thread of the adjusting nut 130 is in threaded connection with the internal thread 116 of the mounting portion 110. Two pieces of the spring plate 140 are stacked together and then placed between the adjustment nut 130 and the cylinder 120.
Of course, in some other embodiments, there may be only one spring plate, or no spring plate may be used, and other elastic members such as compression springs may be used.
When the clamping device is installed, the cylinder 120 firstly passes through the cavity 111 from bottom to top, so that the tapered section 121 and the straight section 122 pass through the upper cavity 112, and the outer diameter of the clamping ring 123 is larger than the inner diameter of the upper cavity 112, so that the clamping ring 123 can be relatively abutted against the clamping groove 114; the spring plate 140 is then placed in the cavity 111, and finally the adjusting nut 130 is screwed on, so that the adjusting nut 130 can abut against the spring plate 140 and the spring plate 140 can be forced to abut against the bottom surface of the snap ring 123 at the same time. To ensure that the cylinder 120 does not retract into the cavity 111 in the free state, a pre-load may be applied to the adjustment nut 130.
The innovation point of the embodiment is mainly embodied in the guide post 100, and the guide sleeve is a guide sleeve structure commonly used in the prior art. For example, the guide sleeve includes a sleeve body, and a positioning cavity is provided in the sleeve body, and corresponds to the cylinder 120. When the die is used, the guide sleeve and the guide pillar 100 are installed in a centering mode, then the guide pillar and the guide sleeve are installed in the fixed die and the movable die of the die respectively, when the die is closed, the cylinder 120 is firstly contacted with the positioning cavity, then the movable die and the fixed die are guided to be accurately closed, after the closing of the die is completed, the installation depth of the guide pillar and the guide sleeve is reasonably set, the cylinder 120 can be slightly pressed downwards by the guide sleeve after the guide pillar and the guide sleeve are close to each other, the elasticity of the spring piece 140 can be overcome by the cylinder 120, and the cylinder 120 is partially retracted into the cavity 111. And the distance of travel of the cylinder 120 is approximately equal to the mold clamping gap required for the aforementioned production.
Since the guide post and the guide sleeve are communicated with the cavity of the mold, during the injection molding process, the material may flow into the cavity from the gap between the cylinder 120 and the cavity 111, so that the movement of the cylinder 120 is blocked. Therefore, in this embodiment, an O-ring 150 is disposed in the sealing groove 115 of the upper cavity 112, and the sealing groove 115 is relatively close to the upper side of the upper cavity 112. Certainly, during installation, the O-ring 150 needs to be sleeved in the sealing groove 115, and then the column 120 penetrates through the cavity 111, so that the O-ring 150 can tightly wrap the outer wall of the straight section 122 of the column 120, and materials are effectively prevented from flowing into the lower cavity 113 from the periphery of the column 120.
In other embodiments, an O-ring seal, such as a Y-ring seal, may not be used.
In order to avoid the inflow of materials as much as possible and ensure the mold closing precision of the guide post and guide sleeve, the gap between the cylinder 120 and the cavity is very small, but the gap cannot be too small, so that the clamping between the cylinder 120 and the cavity 111 is easy to occur due to the too small gap, and in the serious case, the guide post and guide sleeve can be damaged, and even the mold is damaged. Therefore, it is important to ensure the gap between the cylinder 120 and the cavity 111. When traditional guide pillar was installed the template of mould, all adopt interference fit's mode to carry out fixed mounting, the mounting hole in the template can be less than the external diameter of the installation department of guide pillar promptly, after the installation is accomplished, the mounting hole of template can produce radial clamp force to the installation department of guide pillar, and this clamp force can make cavity 111 produce local deformation, after cavity 111 warp, can lead to cylinder 120 and upper cavity 112's clearance to be out of shape, thereby make cylinder 120 when reciprocating, the card dun condition appears.
For this reason, in this scheme, abandoned traditional guide pillar guide pin bushing mounting structure, the mounting hole between the installation department 110 of guide pillar 100 and the template adopts clearance fit's mode, and installation department 110 can freely pass in and out the mounting hole relatively promptly, and the installation between guide pillar 100 and the template is fixed, adopts following mounting means:
still included clamping ring 200, clamping ring 200 have two, two the clamping ring be located the left and right sides of installation department 110 respectively, clamping ring 200 presses the up end of installation department 110. In order to avoid the die joint that the up end of clamping ring 200 exceeds the template, installation department 110 processed round step face 117 at its top surface, and clamping ring 200 is equipped with breach 210 towards one side of installation department 110, breach 210 is the arc, and the radian of this cambered surface with installation department 110's appearance phase-match is equipped with the face 220 that compresses tightly of outstanding on breach 210 in the top of this breach 210 simultaneously, the face 220 that compresses tightly supports the top of step face 117. Referring to fig. 2, the pressing surface 220 and the notch 210 are stepped, and the step is just pressed on the step surface of the mounting portion 110, so that the upper end surface of the pressing ring 200 can be substantially flush with the upper end surface of the mounting portion 110. The arc-shaped surfaces of the two notches 210 can be used for positioning the radial direction of the mounting part 110, so that the guide column 100 is prevented from radial deviation, and the mounting precision of the guide column is kept.
Because the installation and fixation of the guide post completely depend on the compression of the two compression rings 200, the compression rings 200 and the template need to be ensured to be stably installed. Referring to fig. 1 to 3, in the scheme, the clamping ring is fixed by using a specially-made screw. The screw 300 used in the scheme is a countersunk head screw and comprises a head part 310 and a screw rod section 320, wherein a transition section 330 is arranged between the head part 310 and the screw rod section 320, the outer diameter of the transition section 330 is smaller than that of the screw rod section 320, the head part 310 is in a conical shape with a large upper part and a small lower part, the conical degree is 15-20 degrees, and preferably, the conical degree of the head part 310 in the scheme is 18 degrees. And a screwdriver slot is provided in the middle of the head 310. The screw 300 of the present embodiment is similar to a conventional counter-sunk screw of the prior art, but the conventional counter-sunk screw generally does not have a reduced transition section 330 and the taper of the head 310 is substantially 45 °. However, it is most important for the pressing ring 200 to provide an axial locking force, but the radial locking force cannot be too large, so that the screw of the present embodiment is optimized to use a screw with 18 ° taper to fit into the countersunk hole in the pressing ring 200, so that the guide post 100 can be firmly and reliably fixed on the die plate.
Because the guide pin bushing is the spare part of simplex structure, the clamping ring fixed mode of this scheme can be adopted to the mounting means of guide pin bushing and mould template, perhaps adopts traditional interference fit's fixed mode again all can.
Further, as a preferred embodiment, in order to ensure the guiding precision and the installation reliability of the guide pillar and the guide sleeve, the taper of the tapered section 121 of the cylinder 120 is 8 ° to 15 °. Specifically, in the present embodiment, the taper angle is 10 °.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous modifications and substitutions without departing from the spirit of the present invention and within the scope of the appended claims.
