Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to an injection mold mounting device and an injection molding machine. Background Art

[0002] With the increasing update and iteration of injection molding technology and injection molded products, in order to meet different production needs, for example, when performing multi-component injection molding, multiple half molds are required for injection molding. During the production process, a part of the half molds can be first closed, and then another part of the half molds can be closed. To achieve this function, a mold rotating device (or can be called an intermediate turntable of the mold closing unit) is used to carry part of the half molds to rotate, and then close the mold with other half molds.

[0003] In the prior art, fluid media such as water, oil, and gas required for injection molding must pass around the bottom of the template (or can be understood as the intermediate turntable template) to the media distributor. For example, the media can be distributed through a media centralized redistribution block at the bottom of the template and then enter the media distributor. The template generally adopts a solid steel plate structure.

[0004] However, by concentrating the water and oil circuits at the bottom area of the steel plate, the pipe density is high in the narrow space, resulting in the oil being often forced to be heated by high-temperature water, which affects the injection molding product effect and the service life of the equipment. Summary of the Utility Model

[0005] The utility model provides an injection mold mounting device and an injection molding machine, which solve the problems of poor injection molding product effect and short equipment service life existing in the prior art.

Under the condition of not changing the traditional position layout of the turntable bottom plate and the template and with limited space, while realizing the decentralized distribution of the medium pipelines, it can effectively improve the injection molding product effect and the service life of the equipment. Moreover, since the medium channels are opened inside the template, the template of the utility model can cancel the setting of the medium centralized redistribution block, and the medium pipelines do not need to be transitionally connected, reducing the risk of liquid leakage. And compared with the traditional forged solid structure, it has the advantages of light weight and low cost.

[0042] To make the purpose, technical solution and advantages of the present utility model clearer, the implementation mode of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0043] The present utility model provides an injection mold mounting device 1, which is mostly applied to the injection molding scenario of multi-component injection molding. In this application scenario, generally multiple half molds are required. For example, as Figure 1a shown, in an injection molding scenario, half mold A and half mold C are first closed for molding, and the first injection station injects. Then, the turntable bottom plate drives the injection mold mounting device to rotate, for example, rotate 180°. Half mold B and half mold C are closed for molding, and the second injection station injects. In this way, the injection of one product is completed, and this process is repeated. When injecting, each component (such as fluid media like water, oil, gas, etc.) needs to flow through the media pipeline. In the traditional technology, the media pipeline must be wound around from the bottom of the injection mold mounting device to the media distributor, and the media pipelines are stacked in the narrow area between the injection mold mounting device and the turntable bottom plate, resulting in poor heat dissipation and easy mutual influence between the media.

[0044] Please refer to Figure 1 and Figure 2 , the present utility model provides an injection mold mounting device 1, which includes a template 12, a media pipeline 13 (as Figure 6 shown) and a media distributor 14. The media distributor 14 is arranged on the outer peripheral side of the template 12, and two opposite side surfaces of the template 12 are used for mounting the injection mold 2. The media distributor 14 is connected to the injection mold 2.

[0045] The bottom of the template 12 is installed on the turntable bottom plate 11 of the injection molding machine and can rotate following the turntable bottom plate 11;

[0046] The interior of the template 12 has multiple media channels 120, and the multiple media channels 120 are radially distributed from the bottom to the top of the template 12. The media pipeline 13 (as Figure 6 shown) is embedded in the media channel 120 and is connected to the corresponding media distributor 14.

[0047] The above-mentioned radial shape can also be understood as a tree shape, that is, a distribution method that spreads out from bottom to top.

[0048] The present utility model makes full use of the spatial position of the template 12 through multiple media channels 120 built inside the template 12. The multiple media channels 120 are radially distributed, and the technical solution of embedding the media pipelines therein greatly improves the problem of mutual interference during the media transportation process. Under the condition of not changing the traditional position layout of the turntable bottom plate 11 and the template 12 and with limited space, the dispersed distribution of the media pipelines is realized, which can effectively improve the injection molding product effect and the service life of the equipment. Moreover, since the media channels 120 are opened inside the template 12, the template 12 of the present utility model can cancel the setting of the media centralized redistribution block, and the media pipelines do not need to be transitionally connected, reducing the risk of liquid leakage. And compared with the traditional forged solid structure, it has the advantages of light weight and low cost.

[0049] The shape of the medium channel of the present utility model is not limited, and its cross-sectional shape can be, for example, circular, rectangular, elliptical, etc. When a plurality of medium channels 120 are radially divergently distributed, each medium channel 120 can extend linearly, or extend along an arc (as shown in Figure 2 ), or can extend along a curve, such as an S-shaped extension, or can extend along a broken line, such as a V-shaped extension or an L-shaped extension.

[0050] Further, in one embodiment, the medium pipeline 13 (as shown in Figure 6 ) includes a first medium pipeline, a second medium pipeline, and a third medium pipeline. The plurality of medium channels 120 include a first channel group 121, a second channel group 122, and a third channel group 123 that are not connected to each other, as shown in Figure 2 and Figure 3 . Among them, each channel group includes a plurality of connected medium channels 120; the first medium pipeline is arranged in the first channel group 121, the second medium pipeline is arranged in the second channel group 122; the third medium pipeline is arranged in the third channel group 123. Among them, the first medium pipeline, the second medium pipeline, and the third medium pipeline can respectively accommodate different media, for example, can respectively accommodate water, oil, and gas. Since the different channel groups are not connected to each other, the mutual interference between different media is further avoided. Those skilled in the art can understand that the first medium pipeline, the second medium pipeline, and the third medium pipeline can also accommodate the same medium.

[0051] By setting a plurality of channel groups (such as the first channel group 121, the second channel group 122, and the third channel group 123) in the embodiment of the present utility model, and each channel group has a plurality of medium channels 120, the embodiment of the present utility model has rich and wide applicability to meet the requirements of using different media under different injection molding needs. For example, in the face of non-standard requirements put forward by customers, the traditional technology needs to continuously design new turntable bottoms and different medium pipeline layouts, which is very resource-consuming in design and production.

[0052] In one embodiment, as shown in Figure 3 , the second channel group 122 is located between the first channel group 121 and the third channel group 123, and the medium in the first medium pipeline is oil, and the medium in the third medium pipeline is water. With the above structure, the oil pipeline and the water pipeline can be separated by the second channel group 122, further avoiding the situation that the oil is forced to be heated by high-temperature water, which affects the injection molding production process.

[0053] In one embodiment, as shown in Figure 2 and Figure 3 , at least part of the medium in each channel group is distributed in a Y shape, for example, as shown in Figure 3As shown, the two medium channels 120 in the first channel group 121 are distributed in a Y shape. The second channel group 122 includes two medium channels extending linearly and several medium channels extending obliquely. Each linearly extending medium channel and each oblique channel connected to it are respectively distributed in a Y shape. The two medium channels 120 in the third channel group 123 are distributed in a Y shape, thereby forming a radial or tree-like structure.

[0054] Furthermore, please refer to Figure 3 , and the multiple medium channels 120 in the second channel group 122 are symmetrically arranged about the axis of the turntable base plate. The multiple medium channels 120 in the first channel group 121 and the multiple medium channels 120 in the third channel group 123 are symmetrically arranged about the axis of the turntable base plate.

[0055] In addition, the template 12 in the embodiment of the present invention can be an integrally formed structure, for example, integrally formed by injection molding or casting process. In other alternative embodiments, it can also be a split structure, such as Figure 4 and Figure 5 shown, the template 12 includes a first half-template 125, a second half-template 126, and a fixing member 127.

[0056] Both the first half-template 125 and the second half-template 126 are provided with a plurality of medium grooves (such as the medium groove 1261 of the second half-template 126). The first half-template 125 and the second half-template 126 are fixed together by the fixing member 127, so that the plurality of medium grooves (not shown in the figure) in the first half-template 125 and the plurality of medium grooves 1261 in the second half-template 126 are closed to form a plurality of medium channels. Among them, the fixing member 127 can be, for example, a fastening bolt.

[0057] Adopting the scheme of fixing two half-templates together with fastening bolts makes the processing material selection of the template more flexible. For example, relatively thin steel plates, such as steel plates with a thickness of 125 mm to 150 mm, can directly meet the processing requirements. Compared with the traditional scheme of forging with a solid steel plate of 250 mm - 300 mm, it can not only greatly reduce the processing cost but also has high processing flexibility.

[0058] Furthermore, please refer to Figure 6, positioning pins 128 and guide pins 129 are provided on the first half template 125 and / or the second half template 126. The first half template 125 and the second half template 126 are positioned to the installation position through the positioning pins 128 and the guide pins 129. The installation position is configured as: the positions where multiple media grooves in the first half template 125 and multiple media grooves 1261 in the second half template 126 are closed to form multiple media channels. Among them, the number and the installation positions of the positioning pins 128 and the guide pins 129 are not limited, and those skilled in the art can set them as needed. In an exemplary embodiment, the number of the positioning pins 128 is 4, which are arranged at the four corners of the edge of the first half template 125. The number of the guide pins 129 is 2, which are respectively arranged at the top edge and the bottom edge of the first half template 125. The length of the guide pin 129 is, for example, slightly greater than the length of the positioning pin 128. The combination of the two can greatly improve the alignment accuracy and installation efficiency of the two half templates.

[0059] In one embodiment, please refer to Figure 1 、 Figure 2 and Figures 4 to 6 , the circumferential top ends (which can be understood as the four corners in this embodiment) of the template 12 all have recessed parts 124, or it can be understood that: the template 12 is integrally in a cross-shaped structure, and its recessed parts 124 can be used to avoid other devices of the injection molding machine and reduce the space occupied by the rotation of the mold 12. In one embodiment, as Figure 4 shown, the injection mold mounting device 1 further includes an auxiliary mounting block 15. The auxiliary mounting block 15 is mounted on one side surface of the turntable bottom plate 11 and is located at the bottom of the template 12. The auxiliary mounting block 15 is used to receive the injection mold. In an exemplary embodiment, the auxiliary mounting block 15 includes two semi-cylindrical blocks. One semi-cylindrical block is fixed to the surface of the turntable bottom plate 11 and the bottom of the first half template 125 by screws, and the other semi-cylindrical block is fixed to the surface of the turntable bottom plate 11 and the bottom of the second half template 126 by screws.

[0060] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
