Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a mold. Background Technology

[0002] Casting is a plastics processing technology that typically involves injecting liquid monomers or prepolymers into a mold cavity under normal pressure, where they are polymerized and solidified to form a workpiece with the same shape as the inner cavity of the mold.

[0003] In related technologies, casting molds typically employ side-opening molds, also known as rotary-opening molds. However, during the production of large-sized products, the internal pressure of the mold cavity is relatively high after molding. If the moving mold is unlocked directly under conditions such as unstable raw materials or incompatible production environments, the moving mold will bounce up directly due to the high pressure of the mold cavity, seriously affecting the personal safety of the operators and posing a serious safety hazard. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a mold that can achieve pressure relief, thereby enabling the mold to open smoothly and ensuring the personal safety of relevant personnel.

[0005] To achieve the above objectives, embodiments of the present invention provide a mold, comprising:

[0006] Base;

[0007] The first mold includes a movable mold and a mold frame. The movable mold is rotatably connected to one side inside the mold frame, and the movable mold can be locked to the mold frame.

[0008] The second mold is connected to the base, and the second mold and the first mold are arranged opposite to each other along a first direction. The moving mold is capable of rotating in a direction away from the second mold.

[0009] A transmission assembly connects the base and the mold frame respectively;

[0010] The moving mold has a first position that forms a cavity with the second mold and a second position that is spaced apart from the second mold. The transmission assembly is configured to enable the moving mold to switch between the first position and the second position along the first direction.

[0011] In some embodiments, the mold further includes a rotating assembly, wherein the moving mold is rotatably connected to the mold frame via the rotating assembly, and the rotating assembly includes:

[0012] The first connector includes a first bent portion and a first connecting hole. The first connecting hole is disposed at one end of the first connector away from the first bent portion. The first connector is connected to the moving mold through the first bent portion.

[0013] The second connector includes a second bent portion and a second connecting hole. The second connecting hole is disposed at one end of the second connector away from the second bent portion. The second connector is connected to the mold frame through the second bent portion.

[0014] A rotating shaft passes through the first connecting hole and the second connecting hole to connect the first connecting member and the second connecting member;

[0015] The second connecting hole is positioned at a height higher than the frame surface of the mold frame along the first direction.

[0016] In some embodiments, the base includes a worktable and a support frame for supporting the worktable, and the transmission assembly has a drive member that passes through the worktable and is connected to the mold frame along the first direction.

[0017] In some embodiments, the driving range of the driving element is 0mm-10mm.

[0018] In some embodiments, the mold further includes a locking member connected to the side of the mold frame opposite to the second mold, wherein in the first position, the locking member can lock the moving mold to the mold frame.

[0019] In some embodiments, a locking block is provided on the first periphery of the moving mold, and a locking groove is provided on the second periphery of the mold frame. When the moving mold is in the first position, the locking block passes into the locking groove.

[0020] In some embodiments, when the moving mold is in the first position, the surface of the moving mold extends out of the frame of the mold frame along the first direction toward the mold surface of the second mold.

[0021] In some embodiments, the locking member is rotatably connected to the mold frame, and the locking member has a third position abutting against the moving mold along the first direction and a fourth position that allows the moving mold to rotate.

[0022] In some embodiments, a plurality of locking members are provided, and the plurality of locking members are spaced apart circumferentially along the mold frame.

[0023] In some embodiments, the mold further includes an elastic element, one end of which is connected to the base and the other end to the mold frame, the elastic element having an elastic force capable of moving the mold frame away from the base.

[0024] According to the above embodiments, the present invention has at least the following beneficial effects:

[0025] In the technical solution of this application, when it is necessary to open the mold to remove the workpiece, the transmission component in the mold can drive the mold frame to move the moving mold along the first direction to the second position, thus separating the moving mold from the second mold. The high pressure accumulated in the mold cavity can then be released through this gap. Compared to ordinary side-opening molds, this avoids the situation where the moving mold bounces directly due to the high pressure inside the mold cavity after being unlocked, ensuring the safety of relevant operators and extending the service life of the mold. After depressurization, the moving mold can be unlocked and rotated to open in the direction away from the second mold. Compared to opening the mold directly without depressurization, this solution uses an active depressurization method, which is smoother and has less impact on the product in the mold cavity, thereby ensuring product quality and improving the product yield. When the mold needs to work again, simply drive the transmission component to move the moving mold in the opposite direction of the first direction to the first position, where the moving mold abuts against the second mold to form the mold cavity. The overall operation is convenient and quick, improving the production efficiency of the mold. Compared to the solution that directly moves the moving mold away from the second mold to remove the workpiece, the solution proposed in this application has a shorter movement distance of the moving mold during pressure relief, which can ensure the accuracy of mold movement, reduce mold wear, and save production costs.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] Casting is a plastics processing technology that typically involves injecting liquid monomers or prepolymers into a mold cavity under normal pressure, where they are polymerized and solidified to form a workpiece with the same shape as the inner cavity of the mold.

[0053] In related technologies, casting molds typically employ side-opening molds, also known as rotary-opening molds. However, during the production of large-sized products, the internal pressure of the mold cavity is high after molding. If the moving mold is unlocked directly under conditions such as unstable raw materials or incompatible production environments, the moving mold will rapidly bounce up due to the high pressure from the mold cavity, seriously affecting the personal safety of the operators and posing a serious safety hazard.

[0054] In view of this, refer to Figures 1 to 7 This invention proposes a mold 10, which can be applied to various processing methods such as injection molding and casting. For ease of description, the injection mold 10 is used as an example below. Specifically, the mold 10 includes a base 100, a first mold 200, a second mold 300, and a transmission assembly 400.

[0055] The base 100 is a component that supports the first mold 200 and the second mold 300. Different shapes and structures of the base 100 can be designed according to the specific structures of the first mold 200 and the second mold 300 and actual usage requirements. In some embodiments of the present invention, the base 100 is exemplified by a combination of the workbench 110 and the support frame 120, with reference to... Figures 1 to 5 .

[0056] The first mold 200 refers to a part of the main structure used to form the workpiece. The first mold 200 includes a moving mold 210 and a mold frame 220, see reference. Figures 1 to 7 The moving mold 210 is rotatably connected to one side inside the mold frame 220, meaning the moving mold 210 can open or close relative to the mold frame 220. (See reference...) Figure 1 and Figure 3 Mold 10 is in the open position. (Refer to...) Figure 2 The mold 10 is in a closed state. The first mold 200 can be made of various metal materials. In some embodiments, the first mold 200 can be made of manganese steel. In another embodiment, the first mold 200 can be made of carbon steel, depending on the actual situation.

[0057] During the workpiece forming process, the moving mold 210 can be locked inside the mold frame 220, that is, the moving mold 210 and the mold frame 220 can be in a relatively static state. In some embodiments of the present invention, the moving mold 210 is locked by a long strip-shaped locking member 600.

[0058] The second mold 300 refers to another part of the main structure used to form the workpiece, and the second mold 300 is detachably connected to the base 100. The material selection of the second mold 300 is similar to that of the first mold 200, and will not be repeated here. In this embodiment of the invention, the second mold 300 is made of the same carbon steel material as the first mold 200.

[0059] The second mold 300 and the first mold 200 are arranged opposite each other along the first direction Z. It should be noted that the first direction Z can be horizontal, vertical, or inclined, depending on the specific circumstances. For ease of understanding and description, some embodiments of the present invention are illustrated using the vertical direction as an example.

[0060] Before the workpiece is formed, the moving mold 210 needs to be rotated in a direction close to the second mold 300 to close the mold 10 and form a mold cavity. When it is necessary to open the mold, the moving mold 210 needs to be rotated in a direction away from the second mold 300 to open the mold 10.

[0061] The transmission assembly 400 is connected to both the base 100 and the mold frame 220. It is understood that one end of the transmission assembly 400 can be detachably connected to the base 100, and the other end can be detachably connected to the mold frame 220. The transmission assembly 400 has multiple power sources. In some embodiments, the transmission assembly 400 can be driven by an electric motor. In other embodiments, the transmission assembly 400 can be hydraulically driven. In still other embodiments, the transmission assembly 400 can be pneumatically driven. This embodiment of the invention uses a hydraulically driven transmission assembly 400 as an example. Specifically, the transmission assembly 400 includes a driving member 410.

[0062] Reference Figure 4The moving mold 210 has a first position relative to the second mold 300. In the first position, the moving mold 210 abuts against the second mold 300 and forms a mold cavity, the interior of which can be used to mold various workpieces. (Refer to...) Figure 5 The moving mold 210 also has a second position relative to the second mold 300. In the second position, the moving mold 210 is spaced apart from the second mold 300. It should be noted that the spaced apart here refers to the spaced apart between the moving mold 210 and the second mold 300 along the first direction Z. The transmission assembly 400 is configured to enable the moving mold 210 to switch between the first position and the second position along the first direction Z.

[0063] In the technical solution of this application, when it is necessary to open the mold 10 to remove the workpiece, the transmission component 400 in the mold 10 can drive the mold 210 frame to move the moving mold 210 along the first direction Z to the second position, so that the moving mold 210 is separated from the second mold 300. The high pressure accumulated in the mold cavity can be released through the gap. Compared with ordinary side-opening molds 10, this can avoid the situation where the moving mold 210 is directly bounced up due to the high pressure inside the mold cavity after being unlocked, thus ensuring the personal safety of relevant operators and extending the service life of the mold 10. After the pressure is released, the moving mold 210 can be unlocked and rotated to open in the direction away from the second mold 300. Compared with the case of opening the mold directly without pressure release, this solution adopts an active pressure release method, which is smoother and has less impact on the product in the mold cavity, thereby ensuring product quality and improving the product yield. When mold 10 needs to be used again, the transmission assembly 400 simply drives the moving mold 210 to move in the opposite direction of the first direction Z to the first position, where the moving mold 210 abuts against the second mold 300 to form a mold cavity. The overall operation is convenient and quick, improving the production efficiency of mold 10. Compared to the solution of directly moving the moving mold 210 away from the second mold 300 to remove the workpiece, the solution of this application has a shorter movement distance of the moving mold 210 during pressure relief, thereby ensuring the accuracy of mold 10 movement, reducing mold 10 wear, and saving production costs.

[0064] In some embodiments, refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The mold 10 also includes a rotating assembly 500, which enables the moving mold 210 to rotate relative to the mold frame 220. The moving mold 210 is rotatably connected to the mold frame 220 via the rotating assembly 500. Specifically, the rotating assembly 500 includes a first connecting member 510, a second connecting member 520, and a rotating shaft 530.

[0065] Reference Figure 6The first connector 510 includes a first bent portion 511 and a first connecting hole 512. The first bent portion 511 refers to the bent part of the first connector 510, and can be configured with various bending angles, depending on the required rotation range of the moving mold 210 and the structure of the second connector 520. The first connector 510 is detachably connected to the moving mold 210 via the first bent portion 511. The first connecting hole 512 is located at the end of the first connector 510 opposite to the first bent portion 511. The first connecting hole 512 can be a circular hole.

[0066] Reference Figure 7 The second connector 520 includes a second bent portion 521 and a second connecting hole 522. The second bent portion 521 is similar in configuration to the first bent portion 511, and will not be described again here. The second connector 520 is detachably connected to the mold frame 220 via the second bent portion 521. The second connecting hole 522 can be the same as the first connecting hole 512, both being round holes.

[0067] Reference Figure 3 The rotating shaft 530 can pass through the first connecting hole 512 and the second connecting hole 522 to connect the first connecting member 510 and the second connecting member 520. The second connecting hole 522 is positioned at a height higher than the frame surface 221 of the mold frame 220 along the first direction Z. It should be noted that the frame surface 221 of the mold frame 220 here refers to the frame surface 221 of the mold frame 220 that is away from the second mold 300.

[0068] The rotating assembly 500 allows the moving mold 210 to rotate and open relative to the second mold 300, facilitating the removal of the molded workpiece from the mold cavity and the maintenance of the mold 10. Furthermore, because the second connecting hole 522 is positioned higher than the mold frame 220, the moving mold 210 has a larger rotation range. This prevents the moving mold 210 from scraping against the mold frame 220 during rotation, extending the service life of the mold 10.

[0069] Reference Figures 1 to 5 In some embodiments, the base 100 includes a worktable 110 and a support frame 120. The worktable 110 may be made of steel and is used to support and mount the first mold 200 and the second mold 300. The support frame 120 is used to support the worktable 110. The support frame 120 may be composed of multiple support blocks. In some embodiments, the support blocks may be cubes, and in other embodiments, they may be cylinders. The extension length of the support blocks can be determined according to actual needs. An example of this embodiment is a combination of four cylinders.

[0070] The transmission assembly 400 includes a driving member 410. The driving member 410 includes a driving member 411 and a driven member 412. In this embodiment of the invention, the driving member 411 is exemplified by a cylindrical driving rod and a driven rod. The driving member 410 passes through the worktable 110 along a first direction Z and connects to the mold frame 220. Specifically, the driven rod passes through the worktable 110 and connects to the mold frame 220.

[0071] The transmission assembly 400 enables the mold frame 220 to move closer to or further away from the second mold 300 along the first direction Z. Furthermore, since the drive component 410 passes through the platform, the platform can guide the drive component 410, reducing the swaying of the mold frame 220 during movement.

[0072] In some embodiments, the driving range of the drive member 410 is 0mm to 10mm. That is, the mold frame 220 can move 0mm to 10mm along the first direction Z. It should be noted that the movement stroke of the drive member 410 can be controlled by an external controller 800, and different movement strokes can be set according to actual needs. The external controller 800 can realize the automated control of the drive member 410, improving production efficiency. Compared with the solution of directly moving the moving mold 210 away from the second mold 300 to remove the workpiece, the solution of this application has a shorter movement distance of the moving mold 210 when depressurizing, thereby ensuring the accuracy of the mold 10 movement, reducing the wear of the mold 10, and saving production costs.

[0073] Reference Figures 2 to 5 The mold 10 also includes a locking element 600. In some embodiments, the locking element 600 may be elongated. In other embodiments, the locking element 600 may also be elliptical, depending on the specific circumstances. In this embodiment, the locking element 600 is an elongated structure.

[0074] The locking member 600 is located on the side of the mold frame 220 away from the second mold 300, which can limit the movement of the moving mold 210 in the direction away from the second mold 300. The locking member 600 can lock the moving mold 210 inside the mold frame 220, which facilitates the stability of the mold cavity formed by the moving mold 210 and the second mold 300 and facilitates the processing and forming of the workpiece.

[0075] In some embodiments, a locking block 212 is provided on the first periphery 211 of the moving mold 210. It should be noted that the first periphery 211 of the moving mold 210 can be the portion around the periphery of the moving mold 210 perpendicular to the first direction Z. The locking block 212 can have various structural forms; it can be a rectangular locking block 212 or a trapezoidal locking block 212. The locking block 212 can be integrally formed with the moving mold 210, or it can be a component fixedly connected to the moving mold 210. In some embodiments of the present invention, the locking block 212 is exemplified by a rectangular locking block 212 integrally formed with the moving mold 210.

[0076] The second periphery 222 of the mold frame 220 is provided with a slot 223. It should be noted that the second periphery 222 of the mold frame 220 can be the portion of the mold frame 220 surrounding the internal notch of the moving mold 210. The specific structure of the slot 223 depends on the structural shape of the locking block 212. It is understood that the depth of the slot 223 should be less than the thickness of the mold frame 220, so that when the moving mold 210 is in the first position, the locking block 212 can pass through the slot 223. That is, the mold frame 220 can support the locking block 212 through the slot 223 and limit the movement of the moving mold 210 towards the second mold 300. In addition, the locking block 212 and the slot 223 also serve a guiding function, allowing the moving mold 210 to rotate more accurately to engage with the mold frame 220, improving the sealing of the mold cavity, enhancing product quality, reducing collisions between the moving mold 210 and the mold frame 220, and extending the service life of the mold 10.

[0077] When the moving mold 210 is in the first position, the surface of the moving mold 210 facing the mold surface 213 of the second mold 300 extends out of the frame surface 221 of the mold frame 220 along the first direction Z. It should be noted that the frame surface 221 of the mold frame 220 here refers to the surface of the mold frame 220 facing the second mold 300. The protrusion of the moving mold 210 out of the mold surface 213 facilitates direct contact between the moving mold 210 and the second mold 300, improving the sealing of the mold cavity, increasing the product yield, and reducing production costs.

[0078] In some embodiments, the locking member 600 is rotatably connected to the mold frame 220, meaning the locking member 600 can rotate relative to the mold frame 220. (Refer to...) Figure 2 In the third position, the locking member 600 abuts against the moving mold 210 along the first direction Z, thus limiting the displacement of the moving mold 210. (Refer to...) Figure 3 In the fourth position, the locking member 600 rotates to a position outside the moving mold 210, allowing the moving mold 210 to rotate freely. Rotating the locking member 600 allows the moving mold 210 to switch between the first and second positions, which is convenient and quick to operate and can greatly improve production efficiency.

[0079] Reference Figure 2 Multiple locking elements 600 can be provided, and the specific number can be determined according to the actual situation. This embodiment of the invention takes three locking elements 600 as an example. The multiple locking elements 600 are arranged at intervals along the circumference of the mold frame 220. The setting of multiple locking elements 600 can further improve the reliability of the locking stop mold 210 and ensure the continuous and normal operation of production.

[0080] In some embodiments, refer to Figure 2 , Figure 3 and Figure 6A handrail 900 is also provided on the side of the moving mold 210 opposite to the first mold 200. In this embodiment, the handrail 900 is exemplified by a T-shaped rod structure. The handrail 900 is connected to the end of the moving mold 210 opposite to the rotating connection. The handrail 900 facilitates the opening or closing of the moving mold 210, improving production efficiency.

[0081] Reference Figures 1 to 5 The mold 10 also includes an elastic element 700, which can be a spring. One end of the elastic element 700 is connected to the base 100, and the other end is connected to the mold frame 220. The elastic element 700 has an elastic force that moves the mold frame 220 away from the base 100. The elastic element 700 can be installed in various ways. In this embodiment of the invention, a spring is sleeved on the drive rod as an example. The elastic force generated by the elastic element 700 can reduce the vibration generated by the drive member 410 driving the mold frame 210 to move, extend the service life of the mold 10, and ensure product quality.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
