Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a quick mold change and reference alignment device. Background Technology

[0002] In the heat treatment industry, die-pressing and quenching presses are key equipment for achieving dimensional stability and mechanical properties of precision ring parts such as bearing rings. These types of equipment usually need to have a certain degree of versatility to adapt to the production needs of different specifications of workpieces within the same series. Therefore, when it is necessary to switch production varieties or repair and adjust molds that have been used for a period of time, the disassembly and installation of molds become a necessary and frequent process.

[0003] However, the current mold replacement and benchmark alignment process has revealed many drawbacks in practice. Currently, these operations mainly rely on manual labor. For molds used on large workpieces, which are often enormous and heavy, manual handling and replacement are not only time-consuming and labor-intensive, severely restricting production line changeover efficiency and overall output, but also pose significant safety hazards to on-site operators. Meanwhile, ensuring the precise coaxiality of the upper and lower molds is a core factor determining the precision of the press-quenched finished product. Traditional manual alignment methods heavily rely on the operator's experience and feel, making it difficult to guarantee stability and accuracy. This often leads to alignment errors between the upper and lower molds, ultimately resulting in substandard precision in the press-quenched finished product and an increased product defect rate.

[0004] Besides the challenges of the replacement process, the salt bath quenching process itself presents a thorny technical problem. During the working cycle, the upper mold repeatedly comes into contact with high-temperature molten salt and is exposed to air, causing the molten salt adhering to its surface to rapidly crystallize upon cooling. This hardened crystal layer severely affects the fitting accuracy during the next mold closing, directly compromising the final dimensions of the workpiece and potentially damaging the mold surface, shortening its service life. Existing technologies often fail to address this crystallization problem promptly and thoroughly, unable to fundamentally guarantee the cleanliness and temperature stability of the mold during continuous production, thus affecting process stability and product quality consistency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a quick mold replacement and benchmark alignment device, which solves the problems of inconvenient mold replacement and difficulty in cleaning salt crystals on the mold surface.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick mold replacement and reference alignment device, comprising a base, a multi-functional truss arm fixedly connected to the upper part of the base, a worktable fixedly connected to the upper left side of the base, a lower mold disposed on the upper part of the worktable, an automatic centering structure fixedly connected to the middle part of the worktable, first anti-rotation mechanisms fixedly connected to the left and right sides of the upper part of the worktable, a quick-change plate mechanism fixedly connected to the lower part of the multi-functional truss arm, parallel adjustment mechanisms fixedly connected to the lower left and right sides of the quick-change plate mechanism, an upper mold disposed on the outer side of the quick-change plate mechanism, second anti-rotation mechanisms disposed on the left and right sides inside the upper mold, and a crystal removal component disposed on the upper right side of the base for further removing salt solution crystals.

[0007] Preferably, the crystallization removal component includes a dry ice blasting machine, which is fixedly connected to the upper right side of the base. A connecting pipe is fixedly connected to the output end of the dry ice blasting machine, and a second valve is fixedly connected to the outside of the connecting pipe. A regeneration dock is fixedly connected to the upper right side of the upper middle part of the base, and a guide tube is fixedly connected to the upper part of the regeneration dock. A discharge pipe is uniformly fixedly connected to the inside of the guide tube, and a first valve is fixedly connected to the upper part of the discharge pipe. Second mounting posts are uniformly fixedly connected around the upper right side of the upper middle part of the base. A camera is fixedly connected to the upper part of the second mounting post, and a second mounting frame is fixedly connected to the outside of the second mounting post. A second infrared lamp is fixedly connected to the side of the second mounting frame away from the second mounting post.

[0008] Preferably, a support frame is evenly fixedly connected around the lower perimeter of the base.

[0009] Preferably, a first mounting column is evenly fixedly connected to the four sides of the upper left side of the base, and a first thermal imager is fixedly connected to the upper part of the first mounting column.

[0010] Preferably, the upper mold is located above the lower mold.

[0011] Preferably, the lower mold is located outside the first anti-rotation mechanism, and the automatic centering structure is located in the lower middle part of the lower mold.

[0012] Preferably, the end of the connecting pipe away from the dry ice blaster is fixedly connected to the conduit.

[0013] Preferably, the first valve is electrically connected to the camera, and the camera is electrically connected to the second valve and the dry ice jetting machine.

[0014] Preferably, a first mounting bracket is fixedly connected to the outside of the first mounting post, and a first infrared lamp is fixedly connected to the side of the first mounting bracket away from the first mounting post.

[0015] Preferably, the first thermal imager is electrically connected to the first infrared lamp.

[0016] Working Principle: When the upper mold needs to be changed, the multi-functional gantry hand moves above the loading and unloading platform. The mold is then manually changed using the quick-change mechanism. When the lower mold needs to be changed, the multi-functional gantry hand moves above the worktable. The lifting and loading device lowers the gantry hand into position. A servo motor drives a ball screw to retract the multi-functional gantry hand. A moving trolley transfers the lower mold picked up by the multi-functional gantry hand to the loading and unloading platform. After manual replacement, the multi-functional gantry hand picks up the replaced lower mold and places it on the worktable via the moving trolley and lifting and loading device. The automatic centering structure aligns the mold, achieving automatic centering and rapid switching. This avoids the risk of manual contact with salt solution. The gantry-type structure allows for quick, convenient, accurate, and reliable manual replacement, shortening mold change time. When it is necessary to remove melt adhering to the upper mold... During salt crystallization, the molten salt adhering to the upper mold is melted and crystallized by the thermal radiation of the high-temperature workpiece during the transfer of the red-hot workpiece. During short-term shutdowns, the surface temperature of the upper mold is monitored by a first thermal imager and a first infrared lamp. Once the temperature drops below the set crystallization threshold, the first infrared lamp is activated for auxiliary irradiation and heat preservation, maintaining the state with minimal energy consumption. When further cleaning is required, the upper mold is moved to the recycling dock using a multi-functional gantry crane. The contamination level is assessed by scanning with a camera. If the contamination level is low, the second infrared lamp is activated for economical heat preservation. If significant crystallization is detected, the first valve at the corresponding position is opened, and the dry ice blasting machine is activated and the second valve is opened. Dry ice is then sprayed onto the crystallized area through the discharge pipe for cleaning. This process facilitates cleaning of the mold by crystallizing the salt solution, thus improving the service life of the mold.

[0017] This invention provides a quick mold change and reference alignment device. It has the following beneficial effects: 1. This invention uses a multi-functional truss to grab the lower mold and transfer it to the loading and unloading platform. After manual replacement, the multi-functional truss grabs the replaced lower mold and places it on the worktable. The automatic centering structure is aligned by the automatic centering mechanism, thereby realizing automatic mold centering and rapid switching. This avoids the risk of manual operation coming into contact with salt solution. The use of a plug-in plate structure allows for manual replacement, which is quick, convenient, accurate and reliable, shortening the mold change time.

[0018] 2. This invention utilizes the thermal radiation of the high-temperature workpiece to melt the molten salt crystals adhering to the upper mold during the transfer of the red-hot workpiece. During short-term shutdowns, the surface temperature of the upper mold is monitored by a first thermal imager and a first infrared lamp. Once the temperature drops below the set crystallization threshold, the first infrared lamp is activated for auxiliary irradiation and heat preservation, maintaining the state with minimal energy consumption. The upper mold is then transported to the recycling dock using a multi-functional gantry crane. The contamination level is assessed by scanning with a camera, and a second infrared lamp is activated for economical heat preservation. The first valve at the corresponding position is opened, and simultaneously, a dry ice blasting machine is activated and the second valve is opened. Dry ice is blasted through the discharge pipe to clean the crystallized area, thereby achieving salt crystallization on the mold surface for easy cleaning and improving the mold's service life.
