Description
Technical Field
[0001] This invention relates to the field of metal mold processing technology, specifically to a high-precision guiding device for metal mold hardware parts. Background Technology
[0002] The metal mold guide device is a core structural component that guides the precise positioning and smooth sliding of moving parts in the mold. Its core function is to ensure that all moving parts are precisely aligned and operate synchronously during the mold opening and closing process.
[0003] Currently, metal molds commonly employ a guide structure using guide pillars and guide sleeves during hardware processing. This type of structure is prone to wear and tear over long-term use, leading to decreased guiding accuracy and consequently, mold closing deviations and product dimensional instability. This is especially true in the processing of high-precision hardware parts (such as miniature connectors and precision structural components), where traditional guiding devices struggle to meet micron-level alignment requirements. Furthermore, existing guiding structures are mostly single-guide methods, lacking multi-stage buffering and auxiliary positioning mechanisms, resulting in poor equipment stability and short lifespan. Therefore, there is an urgent need for a guiding device with high precision, high stability, and wear resistance to improve mold lifespan and product quality. Summary of the Invention

The top positions of both inner sides are rotatably connected to guide wheels one. The two guide wheels one are respectively embedded in the two guide rails one and slide along them. The center of both sides of the movable groove is provided with guide rails two below the guide wheels one. The center of the bottom of the movable groove is fixedly connected to a support rod. The top of the support rod is fitted with and slidably connected to a sliding sleeve plate. The two sides of the sliding sleeve plate are fixedly connected to fixed plates. The top of the two fixed plates is fixedly connected to the two sides of the bottom of the movable column. The opposite ends of the two fixed plates are rotatably connected to guide wheels two. The two guide wheels two are respectively embedded in the two guide rails two and slide along them. The bottom of the two fixed plates is fixedly connected to a base block. The opposite ends of the two base blocks are fixedly connected to a slider. The slider is embedded in the guide rails two and slides along them. The top of the base is fixedly connected to both sides of the top. The top of the two side plates is fixedly connected to the two sides of the bottom of the top plate.
[0010] Preferably, a cylinder is fixedly installed at the center of the top of the top plate, and the output end of the bottom of the cylinder extends through to the outside of the top plate and is fixedly connected to the center of the top of the lifting plate. Limiting blocks are fixedly connected to both sides of the center of the bottom of the top plate, and the bottom of the limiting blocks contacts the top of the lifting plate.
[0011] Preferably, a support groove is provided at the center of the bottom of the movable column, and the top of the support rod extends through the interior of the support groove and is slidably connected to the support groove.
[0012] Preferably, a bottom pad is fixedly connected to the bottom of the base block, a control panel is fixedly installed at the top position of the outer end of the side plate located on one side, and limit plates are fixedly connected to both sides of the bottom of the groove.
[0013] Preferably, connecting blocks are fixedly connected to both sides of the bottom of the connecting column, and outer plates are fixedly connected to the bottom of the two connecting blocks. An outer sliding groove is opened at the center of both sides of the support column, and a slider is fixedly connected to the bottom of the two outer plates. The slider is embedded in the outer sliding groove and slides along it.
[0014] Preferably, an auxiliary sliding sleeve is fitted and slidably connected to the top position of the column. Two auxiliary moving slots are opened at the opposite ends of the two side plates. The four auxiliary moving slots are on the same horizontal line as the four columns. One end of the auxiliary sliding sleeve is fixedly connected to the outside of the connecting column. A sliding plate is fixedly connected to the other side of the auxiliary sliding sleeve. An inner support rod is vertically fixedly connected to the center of the auxiliary moving slot. The side of the sliding plate away from the auxiliary sliding sleeve extends into the interior of the auxiliary moving slot and is fitted and slidably connected to the inner support rod.
[0015] Preferably, mold-closing pillars are fixedly connected to the four corners of the bottom of the upper mold base, and mold-closing grooves are opened at the four corners of the top of the lower mold base corresponding to the four mold-closing pillars directly below.
[0016] The method for using a high-precision guide device for metal mold hardware parts includes the following steps:
[0017] Step 1: Start the control panel, check whether the cylinder and guide structure are in the initial position, place the hardware to be processed in the designated position of the lower mold base, and confirm that the mold closing slot and mold closing pillar are aligned correctly.
[0018] Step 2: Start the cylinder via the control panel. The cylinder output pushes the lifting plate downward along the column, causing the upper mold base and connecting column to move downward; the movable column then enters the movable groove of the support column.
[0019] Step 3: During the downward movement of the movable column: Guide wheel 1 rolls along guide rail 1 to achieve initial guidance and limitation; Guide wheel 2 rolls along guide rail 2 to further limit horizontal displacement; Slide bar slides within guide rail 2 to enhance lateral stability and torsional resistance; The cooperative structure of support rod and sliding plate provides rigid support in the vertical direction while effectively preventing the movable column from swaying and shaking during movement.
[0020] Step four: The upper mold base and the lower mold base close together, and the hardware parts are formed under the preset pressure; then the cylinder drives the lifting plate to rise, and each guide structure resets in sequence, ready for the next processing cycle.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] This high-precision guiding device for metal mold hardware effectively limits the horizontal displacement of the movable column through a dual guiding mechanism of guide wheel one and guide rail one, and guide wheel two and guide rail two. This ensures high-precision alignment of the upper and lower mold bases during mold closing, meeting micron-level machining requirements. The design of the support rod and sliding sleeve plate, combined with the sliding of the slide bar within guide rail two, forms a multi-level support and limiting system, significantly improving the device's vibration resistance and stability during high-speed operation. The rolling friction between guide wheel one, guide wheel two, and their corresponding guide rails one and two is far less than traditional sliding friction, reducing wear and extending the service life of the guiding system. The bottom pad and limiting plate further buffer impacts and protect structural integrity. The control panel integrates control of the cylinder operation, making operation simple. The limiting block and auxiliary sliding sleeve effectively prevent overshooting or offset of the lifting plate, improving equipment safety. It is suitable for high-precision machining of various metal mold hardware parts, especially for the mass production of micro-parts and complex structural parts, and has promising industrial application prospects.
[0023] This invention effectively solves the technical problems of rapid accuracy decay and poor stability in traditional guide column and guide sleeve structures by setting a two-stage guide wheel and slide rail system between the above-mentioned movable column and support column, and cooperating with the vertical support structure of support rod and slide sleeve plate, thus realizing a high-precision, long-life, and stable guiding function.
