Abstract
Description
Technical Field
[0001] This invention relates to the field of mold processing technology, specifically a lightweight valve body die-casting mold. Background Technology
[0002] The valve body is a major component of a valve; different mechanical manufacturing methods are used depending on the pressure rating. For example, casting and forging are employed. It has a wide range of applications in various industrial fields, and in the field of mold technology, it is well known that different structural forms of die-casting molds are used to achieve the die-casting process of products.
[0003] In the prior art, such as the valve body die-casting mold in Chinese patent application CN 214720429 U, a fixed mold assembly and a moving mold assembly are provided opposite to the fixed mold assembly. The fixed mold assembly includes a fixed template, a fixed core, and fixed mold inserts. The fixed core is disposed within the fixed template, and the fixed mold inserts are disposed within the fixed core. The fixed mold inserts are arranged in blocks and are detachably connected to the fixed core. The moving mold assembly includes a moving template, a moving core, moving mold inserts, and a sliding unit. The moving core is disposed within the moving template, and the moving mold inserts are disposed within the moving core. The moving mold inserts are arranged in blocks and are detachably connected to the moving core. The sliding unit is disposed on the moving template and located on both sides of the moving core. The sliding unit drives the moving core to move horizontally. Through the above method, this utility model can extend the service life of the mold and reduce the mold replacement cost. Moreover, replacing individual small inserts facilitates operation, reduces mold maintenance time, and improves production efficiency.
[0004] While the aforementioned equipment can extend the service life of molds and reduce mold replacement costs, and facilitate operation by replacing individual small inserts, thereby reducing mold maintenance time and improving production efficiency, some complex workpieces require demolding after cooling and forming during the die-casting process of lightweight valve bodies. This requires manual demolding using irregular demolding equipment, which can easily damage the workpieces. This is not only time-consuming and labor-intensive, increasing labor costs, but also makes it difficult to accurately locate the parting surface of the mold during the design process due to its complex shape, resulting in lower precision after the valve body is processed.

[0018] In this invention, through the action of a lateral moving mechanism, a rotating demolding mechanism, a pressing mechanism, a demolding drive mechanism, and a transport mechanism, the raw material is first injected into the inside of the pressing mechanism via an injection tube. This effectively allows the lightweight valve body to cool and solidify inside the pressing mechanism. After cooling and solidification, two second electric telescopic rods pull the side pressing templates to move in opposite directions, causing the two side pressing templates to separate from the outer wall of the bottom pressing template, thus allowing flow on both sides. Subsequently, the first electric telescopic rod drives the linkage plate to move laterally, thereby moving the top pressing mechanism and the valve body to one side. Then, two drive motors drive the drive rod to rotate the adjusting block vertically by 90°, which allows the top valve body to separate from the inside of the pressing mechanism and fall into the transport mechanism for conveying, thus enabling automated demolding. Furthermore, the valve body forming mechanism using multiple pressing templates simplifies the parting surface between the forming modules and the fixed mold, facilitating demolding.
[0019] The equipment integrates injection molding, cooling, demolding, and transportation into a single production process, which can effectively reduce manual operations, saving costs and greatly improving the efficiency of die casting. Attached Figure Description

[0036] The molding mechanism 4 includes a cylinder 401. The output end of the cylinder 401 is fixedly fitted with a top pressing template 402. The top of the top pressing template 402 is fixedly connected to an injection tube 403. The outer wall of the top pressing template 402 is movably fitted with a bottom pressing template 404. The outer wall of the bottom pressing template 404 is provided with two sets of embedding grooves 405. The inner surface of the two sets of embedding grooves 405 is movably fitted with embedding blocks 406. The outer side of the outer wall of the two sets of embedding blocks 406 is fixedly fitted with a side pressing template 407.
[0037] First, the two sets of embedding blocks 406 can be movably embedded in the two sets of embedding slots 405 respectively, and the two side pressure plates 407 can be movably embedded on one side of the outer wall of the bottom pressure plate 404 respectively. Finally, the cylinder 401 drives the top pressure plate 402 to extend and retract to the top of the bottom pressure plate 404, forming a cavity between the inner surface walls of the top pressure plate 402, the bottom pressure plate 404 and the two side pressure plates 407.

A first electric telescopic rod 203 is fixedly inserted between the inner surface walls of the mounting groove 202. The output end of the electric telescopic rod 203 is fixedly fitted with a linkage plate 204. A first placement plate 205 is fixedly installed on one side of the outer wall of the linkage plate 204.

Two telescopic guide columns 104 are fixedly installed on the top of each of the two first mounting plates 102. A top plate 105 is fixedly fitted between the tops of the two telescopic guide columns 104. A hole 106 is opened at the center of the top of the top of the top plate 105. Four support discs 107 are fixedly inserted into the bottom of the support base plate 101.
[0039] In use, the two drive motors 305 first drive the drive rods 303 to rotate inside a set of rotating slots 302. During the rotation, the drive rods 303 drive the adjusting block 304 to rotate longitudinally. During the rotation, the bottom pressing plate 404 and the adjusting block 304 are made perpendicular to each other. During the vertical process, the top-injected product can be demolded. Example
[0040] according to Figures 2-8As shown, the demolding drive mechanism 5 includes two first mounting brackets 501, each with a mounting hole 502 at its bottom. A second electric telescopic rod 503 is fixedly mounted on the inner wall of each mounting hole 502. The transport mechanism 6 includes a conveyor frame 601. A set of rotating holes 602 are pre-set inside the conveyor frame 601. Bearings 603 are fixedly inserted into the inner wall of each set of rotating holes 602. Rollers 604 are fixedly inserted between the inner walls of multiple sets of bearings 603. A conveyor belt 605 is movably sleeved between the outer walls of multiple sets of rollers 604. A second placement plate 606 is fixedly mounted on the outer wall of the conveyor belt 605. Four support columns 60 are fixedly inserted into the bottom of the conveyor frame 601. 7. The outer walls of cylinder 401 are all fixedly inserted into the inside of hole 106, the outer walls of conveyor frame 601 are all fixedly inserted into the inside of support base plate 101, the outer walls of two sliders 206 are all slidably embedded in the inside of sliding groove 103, the outer walls of two first mounting plates 102 are fixedly installed on one side of the outer wall of second mounting plate 201, one side of the outer wall of two first mounting brackets 501 is fixedly connected to the outer wall of top plate 105, the bottom of adjusting base 301 is fixedly installed at the top center of first placement plate 205, the output ends of two second electric telescopic rods 503 are all fixedly connected to one side of the outer wall of side pressure template 407, and the top of adjusting block 304 is fixedly connected to the bottom of bottom pressure template 404.
[0041] Firstly, under the action of a set of bearings 603, the inner ring and outer ring can rotate under the action of the internal balls. During the rotation, the rollers 604 are driven to rotate, thereby driving the conveyor belt 605 to rotate, so as to continuously convey the valve body inside the second placement plate 606 and transport it.
[0042] The operating method and working principle of this device are as follows: At the beginning of operation, the raw material enters the molding mechanism 4 through the injection tube 403. The material then cools and solidifies inside the molding mechanism 4. After cooling and solidification, the two second electric telescopic rods 503 drive the two side pressing plates 407 to move in opposite directions, disengaging them from the outer wall of the molding mechanism 4, thus connecting the two sides of the two molding mechanisms 4. Simultaneously, the top cylinder 401 drives the top pressing plate 402 to move towards each other, causing the multiple pressing plates to separate. Then, the first electric telescopic rod 203, through its telescopic property, pushes the linkage plate 204 and the first placement plate 205 to move longitudinally. During this movement, the two sliders 206 slide and embed themselves inside the sliding groove 103, and in conjunction with the longitudinal movement, drive the first placement plate 205 to move longitudinally. Plate 205 and linkage plate 204 move to one side of the outer wall of the equipment. After moving to one side, the two drive motors 305 can drive the drive rod 303 to rotate inside a set of rotating grooves 302, and drive the adjusting block 304 and the bottom pressing plate 404 at the top to rotate, so that they are kept in a 90-degree position relationship. The valve body that is cooled and formed inside the pressing mechanism 4 can be placed into the inside of the transport mechanism 6 for conveying, thereby performing automated demolding. Through the valve body forming mechanism of multiple pressing plates, the parting surface between the forming module splicing and the fixed mold is simple, which facilitates demolding. The equipment integrates injection molding, cooling, demolding and transportation into one production process, which can effectively reduce the manual operation process, not only saving costs, but also greatly improving the efficiency of die casting.
[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
