Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to a valve mold that can be quickly demolded. Background Technology
[0002] As a core tool in industrial production, mold technology has undergone a leapfrog development from traditional manual manufacturing to modern intelligent manufacturing.
[0003] According to a public disclosure (publication number: CN219151504U), a valve casting mold structure with rapid demolding is provided: It includes a lower mold plate, a supporting side plate fixedly connected to the top of the lower mold plate, an upper mold plate fixedly connected to the top of the supporting side plate, a lower mold base fixedly installed at the top center of the lower mold plate, supporting side plates symmetrically arranged on both sides of the lower mold base, an upper mold base connected to the top of the lower mold base, and a supporting seat fixedly connected to the inner wall of the left supporting side plate. This utility model, through the setting of a corrugated pipe and a disassembly structure, can utilize the deformation of the corrugated pipe to remove the casting pipe from the pipe groove, avoiding the problem of liquid in the pipe groove cooling and solidifying and sticking to the bottom of the casting pipe, thus preventing difficulty in demolding. Furthermore, after the corrugated pipe has been used for a period of time, it can be separated from the discharge pipe and the casting pipe, allowing for cleaning or replacement of the corrugated pipe and preventing blockage that could prevent normal casting.
[0004] In the aforementioned application, the cooperation between the lower template and supporting side plates and other components makes it difficult to solve the problem of material adhesion and sticking to the inner surface of the mold during injection molding, resulting in low demolding efficiency. Therefore, we propose a valve mold that can be demolded quickly. Utility Model Content

[0012] There are two limiting blocks, which are symmetrical about each other along the central axis of the concave block. The inner side of the concave block is slidably connected to the inner side of the lower mold box. Its function is to ensure that the concave block can be stably engaged with the limiting block during the movement, thereby further fixing the mold and improving the safety of demolding.
[0013] The side of the limiting block two is located on the displacement trajectory of the side of the concave block. The circumferential surface of the telescopic end of the cylinder three penetrates and slides through the side of the fixing plate three. Its function is to ensure that the cylinder three can stably push the concave block during the telescopic process, thereby achieving effective demolding of the mold.
[0014] According to another aspect, at least one embodiment of the present invention also provides a valve mold that can be quickly demolded, including a pneumatically assisted demolding device.

[0035] like Figures 1-7 As shown, it illustrates a valve mold that can be quickly demolded according to an embodiment of the present invention, including an upper mold box 1, a lower mold box 2 at the bottom of the upper mold box 1, a demolding device 3 inside the lower mold box 2, a locking post 4 fixedly connected to the top of the lower mold box 2, and a locking hole 5 on the side of the upper mold box 1.
[0036] The demolding device 3 includes a first fixing plate 301, the side of which is fixedly connected to the side of the lower mold box 2. A first cylinder 302 is provided on the side of the first fixing plate 301. An inclined slider 303 is fixedly connected to the telescopic end of the first cylinder 302. A limit block 304 is slidably connected to the side of the inclined slider 303. A second fixing plate 305 is fixedly connected to the side of the lower mold box 2. A second cylinder 306 is provided on the side of the second fixing plate 305. A pad 307 is fixedly connected to the telescopic end of the second cylinder 306. A slide plate 308 is fixedly connected to the side of the pad 307. A mold column 309 is fixedly connected to the side of the slide plate 308. A third fixing plate 310 is fixedly connected to the side of the lower mold box 2. A third cylinder 311 is provided on the side of the third fixing plate 310. A recess 312 is fixedly connected to the telescopic end of the third cylinder 311. A limit block 313 is fixedly connected to the inner side of the lower mold box 2.
[0037] In some examples, the following are also included: the inner side of the lower mold box 2 is fixedly connected to the wear-resistant copper plate 6, and the side of the slide plate 308 is slidably connected to the side of the wear-resistant copper plate 6, which serves to enhance the durability of the mold.
[0038] There are two cylinders 302, fixed plate 301 and inclined slider 303, which are symmetrical about each other along the central axis of the lower mold box 2. Their function is to ensure the stability of the mold during the demolding process and improve the demolding efficiency.
[0039] The side of the limiting block 304 is slidably connected to the side of the inclined slider 303, and the side of the inclined slider 303 is slidably connected to the side of the lower mold box 2. Its function is to ensure that the inclined slider 303 can stably push the limiting block 304 during the movement, thereby realizing the smooth demolding of the mold.
[0040] There are two cylinders 306, pad 307, slide plate 308 and mold pillar 309, and they are symmetrical about the central axis of the lower mold box 2. Their function is to ensure that the mold can be evenly stressed during the demolding process, thereby improving the accuracy and stability of demolding.
[0041] There are two limit blocks 313, which are symmetrical about each other along the central axis of the concave block 312. The inner side of the concave block 312 is slidably connected to the inner side of the lower mold box 2. Its function is to ensure that the concave block 312 can be stably engaged on the limit block 313 during the movement, thereby further fixing the mold and improving the safety of demolding.
[0042] The side of the limiting block 313 is located on the displacement trajectory of the side of the concave block 312. The circumferential surface of the extension end of the cylinder 311 penetrates and slides through the side of the fixing plate 310. Its function is to ensure that the cylinder 311 can stably push the concave block 312 during the extension and retraction process, thereby achieving effective demolding of the mold.
[0043] For example, such as Figure 1-7 As shown, the working principle described above is as follows: When demolding is required, cylinder 302 is first activated. The telescopic end of cylinder 302 pushes the inclined slider 303 to move. The inclined design of the slider 303 allows it to push the limiting block 304 during movement, completing the initial separation of the mold. Next, cylinder 306 is activated. The telescopic end of cylinder 306 pushes the pad 307 and the slide plate 308 to move. The slide plate 308 drives the mold pillar 309 to move, and the mold pillar 309 will be removed from the mold, completing the demolding of the product. At the same time, the side of the slide plate 308 slides on the wear-resistant copper plate 6. The wear-resistant copper plate 6 enhances the durability of the mold and extends its service life. Finally, cylinder 311 is activated. The telescopic end of cylinder 311 pushes the concave block 312 to move. The concave block 312 slides along the side of the limiting block 313 and engages with it, realizing the final step of demolding and improving the safety of demolding.
[0044] like Figures 1-7As shown, this invention illustrates a valve mold capable of rapid demolding in another embodiment of the present invention. It is largely the same as the technical solution described above, so only the differences are emphasized. A pneumatic-assisted demolding device 7 is provided on the side of the lower mold box 2. The pneumatic-assisted demolding device 7 includes an air supply block 701, which is disposed on the side of the fixing plate 2 305. An air supply pipe 1 702 is passed through and fixedly connected to the side of the air supply block 701. A connecting block 1 703 is fixedly connected to the end of the air supply pipe 1 702 away from the air supply block 701. An air supply pipe 2 704 is passed through and fixedly connected to the side of the connecting block 1 703. An annular air groove 705 is provided on the circumferential surface of the mold column 309. A connecting block 2 706 is fixedly connected to the end of the air supply pipe 2 704 away from the connecting block 1 703. Its function is to provide additional power for the demolding process of the mold through the pneumatic-assisted demolding device 7, ensuring that the mold can be demolded smoothly and quickly.
[0045] In some examples, the following are also included: a buffer spring 8 is fixedly connected to the circumferential surface of the air supply pipe 702, a buffer spring 9 is fixedly connected to the side of the buffer spring 8, and the end of the buffer spring 9 away from the buffer spring 8 is fixedly connected to the side of the lower mold box 2. Its function is to buffer the impact force generated by the pneumatic assisted demolding device 7 during the demolding process, prevent damage to the mold due to excessive impact force, and improve the service life of the mold.
[0046] The interior of the annular air groove 705 penetrates the interior of the connecting block 2 706, and the interior of the connecting block 2 706 penetrates the interior of the air supply pipe 2 704. Its function is to ensure that the gas in the pneumatically assisted demolding device 7 can flow smoothly into the annular air groove 705.
[0047] For example, such as Figure 1-7 As shown, when pneumatic-assisted demolding is required, gas enters the first gas supply pipe 702 through the gas supply block 701, then enters the second gas supply pipe 704 through the first connecting block 703, and finally flows into the annular air groove 705 on the circumferential surface of the mold pillar 309. The design of the annular air groove 705 allows the gas to be evenly distributed around the mold pillar 309, providing additional power for the demolding process. At the same time, since the circumferential surface of the first gas supply pipe 702 is fixedly connected with the buffer sheet 8 and the buffer spring 9, when the gas passes through the first gas supply pipe 702, the impact force generated will be absorbed and dispersed by the buffer sheet 8 and the buffer spring 9, thereby preventing damage to the pipeline due to excessive impact force.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
