If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution. Meanwhile, all technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Referring to fig. 1 to 3, a surface positioning guide pillar and guide sleeve includes a guide pillar 1 and a guide sleeve 2, the guide pillar 1 includes an installation portion 11 and a guide portion 12, the guide portion 12 is fixed on a top surface 13 of the installation portion 11, the guide portion 12 includes a boss 121, the boss 121 includes two first positioning planes 122, an included angle between the first positioning plane 122 and a vertical direction is a, and a tangent function value of the included angle a is 1: 10-1: 120 of a solvent; the guide sleeve 2 comprises a positioning groove 21, the guide sleeve 2 comprises a base surface 23, the base surface 23 is located at the lowest end of the guide sleeve 2, the boss 121 is clamped in the positioning groove 21, the positioning groove 21 comprises two second positioning planes 22, and the inclination of the second positioning planes 22 is the same as that of the first positioning plane 122. The second positioning plane 22 is in clearance connection with the first positioning plane 122, and the base surface of the guide sleeve is abutted to the top surface of the mounting part.
Normally, the guide pillar 1 is fixedly installed on the fixed die, and the guide sleeve 2 is fixedly installed on the movable die, and normally, the closed surfaces (i.e. the contact surfaces of the top surface and the base surface) of the guide pillar and the guide sleeve are flush with the parting surface of the die. After the die is closed, the gap between the two positioning planes of the guide pillar and the guide sleeve is minimum.
When the die assembly precision of the die needs to be adjusted, only the closing surfaces of the guide pillar and the guide sleeve need to be staggered. For example, the installation depth of the guide post and the fixed die is increased, so that the base surface of the guide sleeve is away from the top surface when the die is closed, namely, the guide post and the guide sleeve are not completely closed. Because the first locating plane and the second locating plane are inclined, when the die is closed, the larger the distance between the guide pillar and the guide sleeve (namely, the larger the vertical distance between the top surface and the base surface), the larger the gap between the guide pillar and the guide sleeve and the parting surface. The gap can be used to adjust the clamping accuracy of the mold.
In a further preferred embodiment, the guide portion 12 is integrally formed with the mounting portion 11.
In a further preferred embodiment, two mounting holes 123 are provided on the top surface of the guide portion 12, and the mounting holes 123 penetrate through the guide post 1.
Further, in a preferred embodiment, the height of the boss 121 is smaller than the depth of the positioning groove 21.
Further preferred embodiments are those wherein the tangent function value of the angle a is 1:20 or 1:50 or 1: 100. The tangent function value at the included angle is 1: for example, when the distance between the top surface and the base surface of the guide pillar and the guide sleeve is increased by 1mm, and the guide pillar and the guide sleeve are closed, the distance between the parting surfaces is increased by 0.02 mm. Because the distance adjustment between guide pillar and the guide pin bushing is easy a lot relatively, through simple mathematical conversion, can realize the precision adjustment of guide pillar and guide pin bushing when the compound die.
In a further preferred embodiment, the front end and the rear end of the positioning groove 21 penetrate through the guide sleeve 2.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
