Based on this, it is now urgent to improve the existing molds. Utility Model Content

DETAILED DESCRIPTION

[0032] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] One aspect of the present application provides a multi-directional demoulding structure, such as Figures 3 to 14 As shown, one preferred embodiment includes a fixed mold 2 and a first movable core 41, a second movable core 42 and a first telescopic device 51 installed on the fixed mold 2. The first movable core 41 and the second movable core 42 cooperate together to form the entire second plate surface 120 of the cover plate 100; wherein, the second movable core 42 is used to form the buckle portion of the second plate surface 120, and the first movable core 41 is used to form the non-buckle portion area of ​​the second plate surface 120. After the molding of the cover plate 100 is completed, the first movable core 41 can be moved in a direction perpendicular to the second plate surface 120 to realize demolding from the second plate surface 120. The second movable core 42 cooperates with the first movable core 41 through a guide structure, and the second movable core 42 also cooperates with the fixed mold 2 through a locking structure. The first telescopic device 51 can drive the first movable core 41 to perform a demolding action.

[0037] During the demolding process of the first movable core 41, the second movable core 42 can perform a demolding process including a first action and a second action. The first action: the second movable core 42 remains relatively still in the demolding direction of the first movable core 41 with the cooperation of the locking structure, that is, the second movable core 42 and the formed buckle portion remain relatively still in the demolding direction of the first movable core 41; at the same time, the second movable core 42 moves along the opening direction of the buckle portion of the second plate surface 120 under the drive of the guide structure until it is completely separated from the buckle portion. The second action: the locking structure is unlocked, so that the second movable core 42 will move away from the second plate surface 120 synchronously with the first movable core 41, so that the first movable core 41 and the second movable core 42 are completely separated from the second plate surface 120.

[0038] It should be known that when using a traditional mold to produce the cover plate 100, a common demoulding method is to use a driving source to drive the first moving core 41, and also use an additional driving source to drive the second moving core 42. When demoulding, the second moving core 42 first moves along the opening direction of the buckle part under the drive of the corresponding driving source until the second moving core 42 is completely demoulded from the buckle part. If the opening directions of the first buckle 121 and the second buckle 122 included in the buckle part are the same, then the corresponding second moving core 42 only needs one additional driving source; if there are buckles with opposite opening directions in the first buckle 121 and the second buckle 122 included in the buckle part, then the number of additional driving sources will be increased to at least two, and then the two parts of the buckle with opposite opening directions are driven from two opposite directions for demoulding. After the demoulding of the second moving core 42 is completed, the first moving core 41 is driven by the corresponding driving source for demoulding. Based on the above process, the use of traditional molds requires more driving sources, which makes the production cost of the cover plate 100 higher; and there is a demolding sequence between the first movable core 41 and the second movable core 42, which results in the demolding time of the second plate surface 120 corresponding to the cover plate 100 being the sum of the demolding times of the first movable core 41 and the second movable core 42.

[0039] After adopting the technical solution of this embodiment, the first movable core 41 and the second movable core 42 are matched with a guide structure, and the second movable core 42 and the fixed mold 2 are matched with an unlockable locking structure. Therefore, when demolding the second plate surface 120, only a single first telescopic device 51 is needed to drive the first movable core 41 to demold. In the process of demolding the first movable core 41, the second movable core 42 can be separated from the buckle part along the opening direction through the coordinated cooperation of the guide structure and the locking structure, and then move away from the second plate surface 120 with the first movable core 41. Compared with the above-mentioned traditional mold, this embodiment only needs a single driving source for demolding the second plate surface 120, which can effectively reduce the production cost of the mold; at the same time, the entire demolding time of the second plate surface 120 is actually the demolding time of the first movable core 41, which can effectively shorten the production time of the cover plate 100 to improve production efficiency.

[0040] It should be known that the specific structure and working principle of the first telescopic device 51 are well-known to those skilled in the art, so they will not be elaborated in detail here. Common first telescopic devices 51 include linear motors, cylinders, hydraulic cylinders, and the like.

[0041] In this embodiment, there are many specific configuration methods for the guide structure. For ease of understanding, a detailed description will be given below using one of the methods. Figure 4 , Figure 5 and Figures 9 to 12 As shown, the second movable core 42 includes at least one core rod 422 and a sliding plate 421. The sliding plate 421 is slidably mounted on the fixed mold 2 in a direction perpendicular to the second plate surface 120 and cooperates with the fixed mold 2 through a locking structure. The core rod 422 is obliquely slidably mounted on the first movable core 41, one end of the core rod 422 is used to form the buckle portion, and the other end of the core rod 422 is slidably matched with the sliding plate 421 along the opening direction of the buckle portion, and then the core rod 422 is slidably matched with the first movable core 41 and the sliding plate 421 to form a guide structure.

[0042] Therefore, when performing the first action, the sliding plate 421 is locked by the locking structure, so that the sliding plate 421 remains stationary relative to the fixed mold 2; at this time, the first movable core 41 moves away from the second plate surface 120, and due to the inclined sliding cooperation between the first movable core 41 and the core rod 422, the core rod 422 will move synchronously with the first movable core 41; but the movement freedom of the core rod 422 along the demoulding direction parallel to the first movable core 41 is limited by the sliding plate 421, and the driving force applied to the core rod 422 by the first movable core 41 can be decomposed into a first component force parallel to the demoulding direction of the first movable core 41 and a second component force perpendicular to the demoulding direction of the first movable core 41; and then the core rod 422 will move perpendicular to the demoulding direction of the first movable core 41, that is, the opening direction of the buckle part, along the sliding plate 421 under the action of the second component force, until the end of the core rod 422 used to form the buckle part is completely separated from the buckle part. When performing the second action, the sliding plate 421 is unlocked so that the movement restriction of the sliding plate 421 along the demolding direction of the first movable core 41 is released; then the sliding plate 421 can drive the core rod 422 to move synchronously with the first movable core 41 under the drive of the first movable core 41, so that the first movable core 41 and the second movable core 42 are all away from the second plate surface 120 to complete the demolding process.

[0043] It should be known that the specific number of the core rods 422 can be determined according to the number of buckles included in the buckle portion, for example Figure 1 As shown, the buckle portion corresponding to the second plate surface 120 includes four first buckles 121 and one second buckle 122. Among them, a first buckle 121 close to the side can be molded and demolded together with the core used to mold the side plate of the cover plate 100; at the same time, a first buckle 121 and a second buckle 122 are arranged adjacently and have the same opening direction, so they can be molded by the same core rod 422. The specific number of the core rod 422 corresponding to this embodiment is as follows: Figure 4 and Figure 5 Three are shown. At the same time, the inclination direction of the core rod 422 is determined according to the opening direction of the correspondingly formed buckle.

[0044] In this embodiment, there are multiple sliding installation methods between the core rod 422 and the sliding plate 421. For ease of understanding, a detailed description will be given below using one of the installation methods. Figure 5As shown, a plurality of slide grooves 4211 are arranged at intervals on the sliding plate 421. The cross section of the slide groove 4211 can be L-shaped, T-shaped or cross-shaped. It is only necessary to ensure that after the core rod 422 and the slide groove 4211 are slidably matched, the freedom of movement in the direction perpendicular to the sliding plate 421 is limited; T-shaped and cross-shaped are preferably used in this embodiment. A connecting block 4221 is fixedly installed at one end of the core rod 422 close to the sliding plate 421, and a slider 4222 is rotatably installed at at least one end of the connecting block 4221, so that the core rod 422 can slide with the slide groove 4211 through the slider 4222. In order to ensure the sliding stability of the core rod 422, sliders 4222 can be rotatably installed at both opposite ends of the connecting block 4221, and then the core rod 422 slides with the opposite sides of the slide groove 4211 through two opposite sliders 4222.

[0045] In this embodiment, Figure 3 , Figure 4 and Figures 9 to 12 As shown, a sliding cavity 410 is provided in the first movable core 41 and penetrates on both sides along the demoulding direction. The second movable core 42 can be slidably installed in the sliding cavity 410 through a sliding plate 421, and both ends of the sliding plate 421 can extend outside the sliding cavity 410 and cooperate with the fixed mold 2 through a locking structure. Therefore, when performing the first action, the sliding plate 421 can remain stationary with the fixed mold 2 under the locking of the locking structure, and then the sliding plate 421 will slide relative to the sliding cavity 410 under the movement of the first movable core 41 to ensure that the first movable core 41 can move smoothly. When the first action is completed, the sliding plate 421 can just abut against one side of the sliding cavity 410, and then when performing the second action, the sliding plate 421 can move synchronously under the extrusion of the first movable core 41 by abutting against one side of the sliding cavity 410.

[0046] It is understandable that the first movable core 41 and the second movable core 42 can be designed separately, that is, the second movable core 42 can be directly slidably installed on the fixed mold 2, and then the second movable core 42 can be tilted and slidably matched with the first movable core 41 through the core rod 422. However, such a design will lead to a larger installation space requirement between the first movable core 41 and the second movable core 42, and when the core is worn or fails, the first movable core 41 and the second movable core 42 may need to be disassembled at the same time.

[0047] In the present embodiment, a sliding cavity 410 is provided inside the first movable core 41, and then the second movable core 42 is slidably installed in the sliding cavity 410 through a sliding plate 421, so that a modular core group 4 can be formed between the first movable core 41 and the second movable core 42. Compared with the separate design of the first movable core 41 and the second movable core 42, the modular core group 4 can effectively reduce the demand for installation space. Moreover, when the first movable core 41 or the second movable core 42 is worn or fails, the modular core group 4 can be directly removed from the fixed mold 2, and then the first movable core 41 or the second movable core 42 can be replaced, which can provide a convenient and open disassembly and installation environment for the maintenance of the first movable core 41 and the second movable core 42 compared with the traditional method.

[0048] At the same time, the core rod 422 is a relatively important component in the molding mold of the cover plate 100. The second movable core 42 is designed to be inside the first movable core 41. The second movable core 42 can be structurally and anti-fouling protected by the rigid structure of the first movable core 41, thereby effectively improving the service life and molding accuracy of the core rod 422.

[0049] Specifically, Figure 3 and Figure 4 As shown, the first movable core 41 includes a first core block 411 and a second core block 412. The first core block 411 is close to the first telescopic device 51 and is drivingly connected thereto. The second core block 412 is provided with a molding portion for molding the second plate surface 120 on a side away from the first core block 411. At least one side of the two opposite sides of the first core block 411 and the second core block 412 is provided with a sliding groove, and when the first core block 411 and the second core block 412 are connected by fasteners such as bolts to form the first movable core 41, the sliding groove can form a sliding cavity 410 through corresponding cooperation. Therefore, when installing the second movable core 42, the first core block 411 and the second core block 412 can be separated first, and then the sliding plate 421 can be slid and installed in the sliding groove, and then the core rod 422 can be inserted into the second core block 412 by sliding from the outside until the end of the core rod 422 extends into the sliding groove, and finally the end of the core rod 422 is slidably matched with the sliding plate 421 to complete the installation of the second movable core 42.

[0050] In this embodiment, Figure 5 , Fig.13 and Fig.14As shown, the locking structure mainly includes an unlocking block 413, a locking block 21 and a locking groove 4210. When performing the first action, the sliding plate 421 and the fixed mold 2 can be locked by the engagement between the locking block 21 and the locking groove 4210; during this process, the unlocking block 413 installed on the first moving core 41 will move closer to the position of the locking block 21 as the first moving core 41 moves, until the first action is completed, the unlocking block 413 realizes the unlocking of the sliding plate 421 and the fixed mold 2 by cooperating with the locking block 21; and then in the second action, the sliding plate 421 can carry the core rod 422 and move synchronously with the first moving core 41.

[0051] It is understandable that there are two main specific configurations of the locking block 21 and the locking slot 4210. For ease of understanding, the two specific configurations are described in detail below.

[0052] Setting method 1: Figure 2 , Figure 5 , Fig.13 and Fig.14 As shown, the locking groove 4210 is provided at the end of the sliding plate 421, and the locking block 21 is elastically mounted on the fixed mold 2. When performing the first action, the locking block 21 can be engaged with the locking groove 4210 to lock the sliding plate 421. During this process, the unlocking block 413 and the locking block 21 gradually approach each other from the gap, until the first action is completed, the unlocking block 413 can squeeze the locking block 21 to drive the locking block 21 out of the locking groove 4210.

[0053] Arrangement mode 2: The locking groove 4210 is arranged on the fixed mold 2, and the locking block 21 is elastically mounted on the end of the sliding plate 421. When performing the first action, the locking block 21 can be engaged with the locking groove 4210 to lock the sliding plate 421. During this process, the unlocking block 413 and the locking block 21 gradually move closer from the gap, until the first action is completed, the unlocking block 413 can squeeze the locking block 21 to drive the locking block 21 out of the locking groove 4210.

[0054] It can be understood that the above two settings are essentially the same, except that the settings of the locking block 21 and the locking slot 4210 are swapped; therefore, in order to facilitate the description of subsequent contents, the subsequent contents will be described using the above two settings as an example.

[0055] In this embodiment, there are multiple ways to unlock the locking block 21, which can be mainly divided into the following two types.

[0056] Unlock method 1: Figure 7 , Fig.13 and Fig.14As shown, the locking block 21 is elastically slidably installed on the fixed mold 2 through the elastic member 22 along the demoulding direction perpendicular to the first movable core 41; then the unlocking block 413 can squeeze the locking block 21 to achieve unlocking by sliding away from the locking groove 4210 along the demoulding direction perpendicular to the first movable core 41.

[0057] Specifically, Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, the locking block 21 is slidably matched with the mounting groove provided on the fixed mold 2 through the sliding rod, and the elastic member 22 is a spring and is sleeved on the sliding rod, and the two ends of the spring are respectively against the fixed mold 2 and the locking block 21. The locking block 21 is provided with a locking head 211 on one side of the sliding plate 421, and the locking block 21 can be locked by the locking head 211 and the locking groove 4210 provided at the end of the sliding plate 421. In order to ensure the smooth unlocking of the unlocking block 413, the lower part of the locking head 211 can be locked by locking the locking groove 4210, and then the upper part of the locking head 211 can be pressed and matched with the unlocking block 413 to achieve unlocking.

[0058] As for the specific extrusion method between the lock head 211 and the unlocking block 413, one specific example is: an extrusion surface is provided on the side of the upper part of the lock head 211 close to the unlocking block 413 and / or the side of the unlocking block 413 close to the lock block 21; the extrusion surface is an inclined surface or an arc surface, and the lock block 21 and the unlocking block 413 are extruded by the extrusion surface to drive the lock block 21 to slide. In order to further ensure the smooth unlocking, a first extrusion surface 212 can be provided on the side of the upper part of the lock head 211 close to the unlocking block 413, and a second extrusion surface 4130 can be provided on the side of the unlocking block 413 close to the lock head 211. The first extrusion surface 212 and the second extrusion surface 4130 are both inclined, and then through the extrusion of the second extrusion surface 4130 on the first extrusion surface 212, a component force away from the lock slot 4210 can be applied to the lock block 21 to drive the lock block 21 to slide along the installation slot to compress the spring to achieve unlocking.

[0059] Unlocking method 2: the locking block 21 is elastically rotated and installed on the fixed mold 2 through the elastic member 22; and then the unlocking block 413 can squeeze the locking block 21 to rotate in a direction away from the locking groove 4210 to achieve unlocking.

[0060] Specifically, Figure 8As shown, the direction indicated by the dotted arrow is the unlocking direction, and the dotted line indicates the unlocked locking block 21. The locking block 21 is fan-shaped and is rotatably installed on the fixed mold 2 through the rotating shaft 23 installed corresponding to the center position of the fan. The elastic member 22 adopts a torsion spring and is sleeved on the rotating shaft 23. The two ends of the torsion spring are respectively against the fixed mold 2 and the locking block 21; the upper part of the locking block 21 is provided with an extension portion 213 along the radial direction of the rotating shaft 23. The cross-section of the locking groove 4210 provided on the sliding plate 421 is arc-shaped, and the center of the circle corresponding to the locking groove 4210 coincides with the axis of the rotating shaft 23. When the first action is performed, the locking of the sliding plate 421 is achieved by the arc-shaped edge of the locking groove 4210 and the arc-shaped edge of the locking block 21 abutting against each other, and the unlocking block 413 gradually approaches the extension portion 213. When the first action is completed, the extension portion 213 will drive the locking block 21 to rotate around the rotating shaft 23 and compress the torsion spring under the squeezing of the unlocking block 413. During this process, the locking block 21 can be unlocked by relative rotation along the arc edge of the locking groove 4210, thereby ensuring that the sliding plate 421 remains relatively stationary during the unlocking process.

[0061] It should be known that the specific structure and working principle of the elastic member 22 are well known to those skilled in the art. For the unlocking method 1 and the unlocking method 2, the elastic member 22 can also be a spring, etc. In the unlocking method 1 and the unlocking method 2, the purpose of the elastic member 22 is to reset the lock block 21 after unlocking, so that the sliding plate 421 can be automatically locked again in the next molding process.

[0062] It is understandable that both of the above two unlocking methods can meet the needs of this application, and those skilled in the art can choose according to actual needs. For ease of understanding, the entire demoulding process of the second panel 120 will be described in detail below using unlocking method 1 as an example.

[0063] (1) When the second plate surface 120 is formed, Fig. 9 and Fig.13 As shown in (1), at this time, the molding end of the core rod 422 is flush with the molding end of the second core block 412 for molding the required second plate surface 120. At the same time, the sliding plate 421 is locked with the locking head 211 of the locking block 21 through the locking groove 4210 set at the end, and the unlocking block 413 is spaced from the locking block 21.

[0064] (2) When performing the first action, Fig.10 and Fig.13As shown in (2), at this time, the first movable core 41 slides along the fixed mold 2 away from the second plate surface 120 under the drive of the first telescopic device 51. At the same time, the sliding plate 421 is locked with the lock head 211 of the lock block 21 through the lock groove 4210 set at the end, so that the sliding plate 421 together with the core rod 422 remains stationary relative to the fixed mold 2 in the demoulding direction of the first movable core 41. And in the process of the movement of the first movable core 41, the core rod 422 can be driven to slide along the sliding plate 421 perpendicular to the demoulding direction of the first movable core 41 by cooperating with the inclined sliding of the core rod 422, so that the molding end of the core rod 422 gradually disengages from the buckle portion. In this process, the first movable core 41 can also drive the unlocking block 413 to continue to approach the lock block 21.

[0065] (3) When the first action is about to be completed, Fig.11 and Fig.14 As shown in (1), at this time, the core rod 422 has been demolded from the buckle portion by sliding along the sliding plate 421, and the first movable core 41 has brought the unlocking block 413 close to and started to contact the lock head 211. As the unlocking block 413 squeezes the first extrusion surface 212 on the lock head 211 through the second extrusion surface 4130, the lock block 21 can compress the elastic member 22 and move away from the lock groove 4210 until the lock head 211 is completely out of the lock groove 4210, and the first action is completed, and at this time the sliding plate 421 just abuts against the side of the sliding cavity 410 close to the second plate surface 120.

[0066] (4) When performing the second action, Fig.12 and Fig.14 As shown in (2), since the lock between the sliding plate 421 and the locking block 21 has been released, as the first movable core 41 continues to move, the sliding plate 421 can move synchronously with the first movable core 41 under the resistance of the sliding cavity 410 close to the second plate surface 120. At this time, the first movable core 41 and the sliding plate 421 remain relatively still, and the core rod 422 and the first movable core 41 will also remain relatively still and move synchronously with the first movable core 41 until the first movable core 41 and the second movable core 42 are all away from the second plate surface 120.

[0067] (5) When the core group 4 is reset after the cover plate 100 is completely demolded, the first telescopic device 51 drives the first movable core 41 in reverse to move closer to the cavity position. During this process, the second movable core 42 can move synchronously with the first movable core 41 as a whole through the inclined sliding cooperation of the core rod 422 and the first movable core 41, until the locking groove 4210 on the sliding plate 421 is aligned with the locking block 21 again, the locking block 21 can extend out under the reset elastic force of the elastic member 22 and engage with the locking groove 4210 through the locking head 211, or after the locking head 211 extends into the locking groove 4210, the sliding plate 421 and the fixed mold 2 are abutted, that is, the locking block 21 only needs to lock the sliding plate 421 along the demolding direction, and the locking in the reset direction can be achieved by the abutment of the fixed mold 2. Subsequently, the sliding plate 421 will remain stationary relative to the fixed mold 2 , and the first movable core 41 will continue to reset, so that the core rod 422 can achieve reset sliding along the sliding plate 421 through the inclined sliding cooperation with the first movable core 41 .
