[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0027] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they actually express the meaning of order according to the context, they should be understood as being merely for the purpose of distinction.
[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0029] A mold with a multi-point support structure includes a hot runner plate 1 and a panel 2. The hot runner plate 1 includes a mating surface 11 that cooperates with the bottom of the panel 2, and a cavity 3 that is recessed from the mating surface 11 and is used to accommodate the hot runner system. The cavity 3 is provided with multiple raised platforms 4, and a support structure 5 for respectively supporting the multiple platforms 4 and the bottom of the panel 2.
[0030] The present invention provides a mold with a multi-point support structure. The hot runner plate is provided with a cavity to accommodate the hot runner system, and multiple platforms of varying heights are provided on the cavity. The support structure is used to support the plate between the multiple platforms and the panel, thereby improving the strength of the hot runner plate at the locations corresponding to the support structure. This avoids the occurrence of stress concentration and insufficient strength of the hot runner plate due to the uneven thickness of the hot runner plate caused by the provision of the cavity.
[0031] In this embodiment, in order to accommodate the hot runner system and other components, the hot runner plate has a cavity on which the thickness is thinner at locations where there are more and denser parts and where space needs to be given, and a thickness thicker at locations where there are fewer parts. This creates multiple platforms of different heights in order to further utilize the space in the cavity and thicken the hot runner plate where it can be thickened, thereby ensuring the strength of the hot runner plate.
[0032] Furthermore, as a preferred embodiment of this solution but not a limitation, the platform 4 includes a first platform 41, and the support structure 5 includes a first support head 51 disposed on the first platform 41 and extending from the first platform 41 to be flush with the mating surface 11. The first support head is fixed to the first platform, thereby enhancing the strength of the first support head at the position where the first support head contacts the hot runner plate. At the same time, when the hot runner plate and the panel are mated and installed, the first support head plays a supporting role, supporting between the hot runner plate and the panel, thereby enhancing the overall strength of the mold and maintaining the precision of the mold.
[0033] Furthermore, as a preferred embodiment of the present invention but not a limitation, the cavity 3 includes an opening 31 connected to the side of the hot runner plate 1, and the first support head 51 is provided at a position corresponding to the opening 31. The cavity is connected to the side of the hot runner plate, so that the strength at the opening position of the hot runner plate is insufficient. Therefore, the first support head is provided at the opening position, which can enhance the strength at the opening position of the hot runner plate, thereby enhancing the overall strength of the mold and maintaining the accuracy of the mold. The opening is provided for connecting the hot runner system with the outside world. Figure 2 、 Figure 3 As shown, the hot runner system 7 is a part of the hot runner system in the mold.
[0034] Furthermore, as a preferred embodiment of this solution but not a limitation, the first support head 51 is provided with an inclined surface 511 for making way for the hot runner system extending outside the side of the hot runner plate 1. The inclined surface 511 and the opening 31 form a clearance space 512 that gradually narrows from the outside to the inside of the hot runner plate 1. The hot runner system has multiple pipes connecting to the outside of the mold, and the pipes are bent at the opening. The inclined surface is used to make way for the pipes, allowing the multiple pipes to gradually transition to the outside of the mold.
[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the cavity 3 includes a bottom surface 32, and the support structure 5 includes a plurality of support columns 53 provided on the bottom surface 32 to make way for the hot runner system and extending from the bottom surface 32 to be flush with the mating surface 11. In this embodiment, the support columns play the role of strengthening the hot runner plate in two ways. The first is that the support columns and the hot runner plate are integrally formed and set when the mold is initially manufactured. The support columns integrally formed with the hot runner plate can more effectively strengthen the strength of the hot runner plate. The second is a support column fixedly connected to the hot runner plate. The support column is set according to the excess space position on the cavity, can be set according to different hot runner systems, or can be flexibly set when the hot runner system is changed to strengthen the strength of the hot runner plate.
[0036] Furthermore, as a preferred embodiment of this solution but not a limitation, the platform 4 includes a second platform 42 lower than the first platform 41, and the support structure 5 includes a plurality of second supports 52 disposed on the second platform 42 and extending from the second platform 42 to be flush with the mating surface 11. The second supports are used to support between the hot runner plate and the panel, strengthening the overall strength of the mold and maintaining the mold's precision. Depending on the requirements of the mold design, the platform may also include a third height level, a third platform, etc., with corresponding supports provided on each platform to comprehensively strengthen the overall strength of the mold and maintain the mold's precision.
[0037] Furthermore, as a preferred embodiment of this solution but not limiting, the support structure 5 includes two diagonally-arranged support blocks 57 disposed on the second platform 42, and the second support head 52 is disposed between the two support blocks 57 and diagonally opposite to the two support blocks 57. The diagonally-arranged support blocks provide excellent support for the panel. Furthermore, the space between the two support blocks can also serve as an installation location for the hot runner system. When the hot runner system does not need to pass through the space between the two support blocks, the second support head is provided to enhance the support function and the strength of the hot runner plate.
[0038] Furthermore, as a preferred embodiment of this solution but not limiting, it further includes a sprue bushing 6 and a fastener 61. The support structure 5 includes a sprue bushing support head 54 provided on the cavity 3 and corresponding to the position of the sprue bushing 6. The fastener 61 passes through the sprue bushing 6 and the faceplate 2 and is fixedly connected to the hot runner plate 1. The fastener connects the sprue bushing, the faceplate, the sprue bushing support head, and the hot runner plate, thereby enhancing the tightness and strength of the entire mold.
[0039] Furthermore, as a preferred embodiment of this solution but not a limitation, according to the mold with a multi-point support structure as described above, the support structure 5 is provided with a plurality of connection holes 56 for fixed connection with the hot runner plate 1. In this embodiment, the support structure has multiple connection holes, so that the support structure and the hot runner plate are tightly connected.
[0040] Furthermore, as a preferred embodiment of the present solution but not a limitation, the support structure 5 includes a hot runner support head 55 provided on the hot runner system and extending to be flush with the mating surface 11 .
[0041] The working principle of this embodiment is as follows:
[0042] The present invention provides a mold with a multi-point support structure. The hot runner plate is provided with a cavity to accommodate the hot runner system, and multiple platforms of varying heights are provided on the cavity. The support structure is used to support the plate between the multiple platforms and the panel, thereby improving the strength of the hot runner plate at the locations corresponding to the support structure. This avoids the occurrence of stress concentration and insufficient strength of the hot runner plate due to the uneven thickness of the hot runner plate caused by the provision of the cavity.
