Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically a floating precision positioning structure for mold processing. Background Technology

[0002] Molds are process equipment used in industrial production to shape metal or non-metal materials into specific shapes and sizes. They are widely used in stamping, injection molding, die casting, forging, ceramic molding and other fields. Their core function is to achieve mass production of high-precision parts by precisely controlling the flow or deformation of materials. They are the basic process equipment of modern manufacturing.

[0003] Traditional floating precision positioning structures for mold processing mainly consist of floating positioning pins, floating sleeves, elastic compensation units, guiding mechanisms, and hydraulic buffer modules. The top of the floating positioning pin is a tapered guide, the middle is a cylindrical positioning part, and the bottom is a connecting flange. The floating sleeve is made of self-lubricating bearing steel, with an annular guide groove on its outer circumference. The elastic compensation unit is composed of nitrogen springs or disc springs to provide axial preload. The guiding mechanism consists of a guide groove on the outer circumference of the floating sleeve that engages with a guide key in the mold mounting hole to restrict rotational freedom. Its working principle is as follows: when there is an installation deviation in the mold, the floating sleeve compresses the elastic element and slides along the guide key. The contact point between the positioning pin and the tapered surface of the floating sleeve is automatically adjusted to eliminate radial error. The hydraulic buffer system absorbs the impact force of mold closing through oil damping, avoiding positioning offset caused by rigid collision. The tapered guide guides the positioning pin into the floating sleeve to correct angular deviation. The cylindrical positioning part achieves surface contact with the inner hole of the floating sleeve. The hydraulic chamber pressure is stable, maintaining the positioning state until processing is completed.

[0004] However, traditional floating precision positioning structures used for mold processing are usually fixed structures, which makes it inconvenient to adjust the height of the mold. Since the mold installation height is fixed, it is difficult to meet different processing needs. Utility Model Content

[0005] The purpose of this invention is to provide a floating precision positioning structure for mold processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floating precision positioning structure for mold processing, including a worktable, a plurality of support legs fixedly connected to the bottom of the worktable, an adjustment component fixedly connected to the upper surface of the worktable, an adjustment plate fixedly connected to the outer side wall of the adjustment component, an installation groove provided on the upper surface of the adjustment plate, and a lower mold fixedly connected to the inner wall of the installation groove.

[0010] Preferably, the adjustment assembly includes a fixed rod fixedly connected to the upper surface of the worktable, an adjustment buckle slidably connected to the outer wall of the fixed rod, and the outer surface of the adjustment buckle being fixedly connected to the outer wall of the adjustment plate.

[0011] Preferably, the outer surface of the fixing rod is provided with multiple threaded holes, which are arranged in a linear array, and a limit block is fixedly connected to the end of the fixing rod away from the worktable.

[0012] Preferably, a spring is fitted on the outer surface of the fixing rod, one end of the spring abuts against the upper surface of the worktable, and the other end of the spring away from the worktable abuts against the side of the adjusting buckle closest to the worktable.

[0013] Preferably, the outer surface of the adjusting buckle has a through hole, and a threaded rod is inserted into the inner wall of the through hole. The outer wall of the threaded rod is threaded to the inner wall of the threaded hole. A knob is fixedly connected to the end of the threaded rod away from the through hole, and a plurality of turning protrusions are fixedly connected to the side of the knob away from the threaded rod.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1-4 The present invention provides the following two preferred embodiments: Example 1: A floating precision positioning structure for mold processing includes a worktable 1. Multiple support legs are fixedly connected to the bottom of the worktable 1 to provide stable support for the entire structure. An adjustment assembly 3 is fixedly connected to the upper surface of the worktable 1. An adjustment plate 8 is fixedly connected to the outer wall of the adjustment assembly 3. An installation groove 12 is formed on the upper surface of the adjustment plate 8. A lower mold 7 is fixedly connected to the inner wall of the installation groove 12. The height of the lower mold 7 can be adjusted by adjusting the adjustment assembly 3. A mounting frame 6 is fixedly connected to the upper surface of the worktable 1. A telescopic cylinder 5 is fixedly connected to the upper surface of the mounting frame 6. The output end of the telescopic cylinder 5 is fixedly connected to... The upper mold 4 is connected to a telescopic cylinder 5, which can drive the upper mold 4 to move up and down to realize mold closing and mold opening operations. Connecting plates 9 are fixedly connected to both sides of the upper mold 4. Two vertical plates 2 are fixedly connected to the upper surface of the worktable 1. The two vertical plates 2 are symmetrically arranged. Two guide grooves 10 are opened on the upper surface of the vertical plates 2. Guide rods 11 are slidably connected to the inner walls of the two guide grooves 10. The end of the guide rod 11 away from the guide groove 10 is fixedly connected to the side of the connecting plate 9 close to the vertical plate 2. The cooperation of the guide rod 11 and the guide groove 10 provides guidance for the movement of the upper mold 4, ensuring the stability of the movement of the upper mold 4 and improving the mold closing accuracy.

[0019] In actual use, the telescopic cylinder 5 is activated, which drives the upper mold 4 to move downward. The guide rod 11 slides in the guide groove 10 to ensure that the upper mold 4 descends smoothly. After the upper mold 4 and the lower mold 7 are closed, the mold processing operation is performed. After the processing is completed, the telescopic cylinder 5 is controlled to retract, which drives the upper mold 4 to move upward, completing the mold opening action and taking out the processed mold.

[0020] Example 2: The adjustment assembly 3 includes a fixed rod 301 fixedly connected to the upper surface of the worktable 1. An adjustment buckle 304 is slidably connected to the outer wall of the fixed rod 301. The outer surface of the adjustment buckle 304 is fixedly connected to the outer wall of the adjustment plate 8. The adjustment buckle 304 can slide on the fixed rod 301, thereby driving the adjustment plate 8 and the lower mold 7 to move up and down. A plurality of threaded holes 303 are opened through the outer surface of the fixed rod 301. The threaded holes 303 are distributed in a linear array. A limit block 302 is fixedly connected to the end of the fixed rod 301 away from the worktable 1. The limit block 302 can prevent the adjustment buckle 304 from slipping off the fixed rod 301. A spring 305 is sleeved on the outer surface of the fixed rod 301. One end of the spring 305 abuts against the upper surface of the worktable 1. The end of the spring 305 away from the worktable 1 abuts against the side of the adjusting buckle 304 near the worktable 1. The spring 305 provides a certain elastic support for the adjusting buckle 304, making the adjustment process more stable. A through hole is opened through the outer surface of the adjusting buckle 304. A threaded rod 306 is inserted into the inner wall of the through hole. The outer wall of the threaded rod 306 is threadedly connected to the inner wall of the threaded hole 303. A knob 307 is fixedly connected to the end of the threaded rod 306 away from the through hole. Multiple turning protrusions 308 are fixedly connected to the side of the knob 307 away from the threaded rod 306. The turning protrusions 308 are arranged in a ring array. By holding the turning protrusions 308 and turning the knob 307, the threaded rod 306 can be rotated, realizing the connection and separation of the threaded rod 306 and the threaded hole 303.

[0021] In actual use, when it is necessary to adjust the height of the lower mold 7, first loosen the knob 307 so that the threaded rod 306 disengages from the threaded hole 303. At this time, the adjusting buckle 304 can slide freely on the fixed rod 301. According to the actual processing requirements, move the adjusting buckle 304 up or down. The adjusting buckle 304 drives the adjusting plate 8 and the lower mold 7 fixed on the adjusting plate 8 to move together, thereby adjusting the height of the lower mold 7. After the lower mold 7 is adjusted to a suitable height, align the threaded rod 306 with the threaded hole 303 of the corresponding height on the fixed rod 301, and then tighten the knob 307 to make the threaded rod 306 tightly connected with the threaded hole 303, thereby fixing the adjusting buckle 304 on the fixed rod 301, and thus fixing the height of the adjusting plate 8 and the lower mold 7.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
