Description

Technical Field

[0001] This utility model relates to the field of mold mechanism, specifically to a three-waisted hole guide mechanism and mold. Background Technology

[0002] In applications involving heavy loads and high-frequency repetitive motion, such as mold processing, short-distance linear guide mechanisms are key components for ensuring stable equipment operation.

[0003] While existing linear guide solutions, such as guide post and guide sleeve structures, offer high guiding accuracy, they suffer from structural complexity, large installation space requirements, and high maintenance costs. Simple single-hole guide structures, on the other hand, suffer from limited contact area and insufficient stability, making them prone to misalignment and wear under heavy loads and high-frequency movements, leading to decreased guiding accuracy and impacting mold efficiency and lifespan. Therefore, this technical field desires more short-distance linear guide mechanisms with simple structures, good stability and load-bearing capacity, and adaptability to the heavy-load, high-frequency repetitive movements required by molds, to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a three-waisted hole guiding mechanism and mold.

[0005] To solve the above problems, on the one hand, this utility model provides a three-waisted hole guiding mechanism. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: A three-slotted hole guide mechanism includes: a multi-hole block having several slotted holes parallel to each other in the length direction, each slotted hole including a first slotted hole and two second slotted holes, the two second slotted holes being symmetrically distributed on both sides of the first slotted hole, and the line connecting the centroids of the first slotted hole and the two second slotted holes forming a triangle; a bolt, one bolt passing through each slotted hole, the bolt being movably assembled with the slotted hole; a push rod, one end of which is assembled with the side wall of the multi-hole block, the length direction of the push rod being parallel to the length direction of the slotted hole; and a compression spring, one end of which is assembled with the side wall of the multi-hole block, the push rod and the compression spring being located on both sides of the multi-hole block respectively; wherein, a first bolt passes through the first slotted hole, a second bolt passes through the second slotted hole, and the two second bolts are laterally fixed together by a connecting strip.

[0006] As a further improvement of this utility model, the diameter of the bolt is not greater than the width of the oblong hole, and the triangle formed by connecting the centroids of one first oblong hole and two second oblong holes is the same in shape and size as the triangle formed by connecting the centroids of one first bolt and two second bolts. The triangle formed by connecting the centroids of the first oblong hole and the two second oblong holes is an isosceles triangle.

[0007] As a further improvement of this utility model, the surface of the porous block has a lower groove, one end of the second waist-shaped hole is located on the bottom surface of the lower groove, the lower groove is movably fitted with a wrapping block, and the wrapping block is fixedly assembled with two second bolts; the sidewall of the lower groove restricts the extreme position of the wrapping block's linear movement.

[0008] As a further improvement of this utility model, the opening at one end of the first waist-shaped hole is partially located on the bottom surface of the lower groove, and the first bolt does not contact the wrapping block.

[0009] As a further improvement of this utility model, both ends of the connecting strip are exposed from the wrapping block.

[0010] As a further improvement of this utility model, the two side walls of the lower groove are respectively a first side wall and a second side wall, the distance between the first side wall and the second side wall is equal to the length of the second waist-shaped hole, and the first side wall and the second side wall are parallel to each other.

[0011] As a further improvement of this utility model, the two second bolts also jointly fix a through block, and the wrapping block and the through block are located on both sides of the porous block.

[0012] As a further improvement of this utility model, the two end side surfaces of the porous block are respectively provided with threaded holes and blind holes. The threaded holes are assembled with the top rod, and the blind holes are assembled with the compression spring. The end of the compression spring away from the porous block also contacts a stop block.

[0013] As a further improvement of this utility model, the axial direction of the bolt is parallel to the through direction of the waist-shaped hole, the bolt is divided into an external thread section and a smooth axis section along the axial direction, and the bolt in the waist-shaped hole is the smooth axis section of the bolt.

[0014] On the other hand, a mold includes the three-waisted hole guide mechanism described in any one of the above.

[0015] The beneficial technical effects of using the three-waisted hole guide mechanism of this application are: The three-slotted holes are distributed in a triangular pattern, which is equivalent to providing multiple short guide grooves arranged in different positions to serve the same linear reciprocating motion. This can significantly improve the load-bearing capacity and anti-skew performance of the guide mechanism and is suitable for heavy-duty mold working conditions.

[0016] The second bolt is horizontally fixed by the connecting strip, which strengthens the bond between the different bolts. The bolt is movably assembled with the slotted hole, and the guide direction of the push rod is consistent with the length direction of the slotted hole. Together with the synchronous constraint of the second bolt, the guiding accuracy of short-distance linear motion is guaranteed.

[0017] The overall structure consists of only a perforated block, bolts, top rod, compression spring, and connecting strip, which is simple and compact. This reduces the installation space requirements and maintenance costs, and makes up for the shortcomings of the complex structure of traditional guide post and guide sleeve.

[0024] The beneficial effect of adopting the above technical solution is that the bolt has a linear reciprocating translational degree of freedom in the waist-shaped hole, so the waist-shaped hole acts as a guide groove, and the length of the waist-shaped hole is basically equal to the length that can move linearly.

[0025] The number and distribution of the waist-shaped holes give this linear guide mechanism greater structural strength, enabling it to withstand greater impacts and loads, making it less prone to skew during guidance, and ensuring that it maintains design requirements even after long-term use.

[0026] In some other embodiments of this utility model, the diameter of the bolt is not greater than the width of the oblong hole. The triangle formed by connecting the centroids of one first oblong hole 101 and two second oblong holes 102 is the same in shape and size as the triangle formed by connecting the centroids of one first bolt 4 and two second bolts 5. The triangle formed by connecting the centroids of one first oblong hole 101 and two second oblong holes 102 is an isosceles triangle.

[0027] The beneficial effects of adopting the above technical solution are: the bolt diameter is no greater than the width of the slotted hole, ensuring that the bolt can move freely in the slotted hole and avoiding motion interference.

[0034] The beneficial effects of adopting the above technical solution are: the two ends of the connecting strip 6 are exposed from the wrapping block 8, which facilitates the disassembly and assembly of the connecting strip 6, and at the same time provides an interface for external connection or adjustment, enhancing the adjustability and maintenance convenience of the mechanism.

[0035] like Figure 1 As shown, in some other embodiments of this utility model, the two side walls of the lower groove 103 are a first side wall 1031 and a second side wall 1032, respectively. The distance between the first side wall 1031 and the second side wall 1032 is equal to the length of the second waist-shaped hole 102. The first side wall 1031 and the second side wall 1032 are parallel to each other.

[0036] The beneficial effects of adopting the above technical solution are: ensuring that the wrapping block 8 moves in a straight line, consistent with the guide direction of the waist-shaped hole, improving the motion accuracy and guide stability, and preventing skewing.

[0037] In some other embodiments of this utility model, the two second bolts 5 also jointly fix the through block 9, and the wrapping block 8 and the through block 9 are located on both sides of the porous block 1.

[0038] The beneficial effects of adopting the above technical solution are: forming bidirectional support, enhancing the rigidity of the second bolt 5 and the overall structural strength, preventing the bolt from bending or deforming under heavy load, and improving load-bearing capacity.

[0039] like Figure 1 , Figure 3 As shown, in some other embodiments of this utility model, the two end side surfaces of the porous block 1 are respectively provided with threaded holes 104 and blind holes. The threaded holes 104 are assembled with the top rod 7, and the blind holes are assembled with the compression spring 3.

[0040] The beneficial effects of adopting the above technical solution are: providing stable buffering or restoring force, ensuring the smoothness and restoring accuracy of the mechanism in reciprocating motion, and adapting to the needs of high-frequency motion.

[0041] In some other embodiments of this utility model, the axial direction of the bolt is parallel to the through direction of the waist-shaped hole, and the bolt is divided into an external thread section and a smooth axis section along the axial direction.
