Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] For ease of understanding, Figure 1A schematic diagram of the central control panel in this embodiment is shown. It can be seen that the overall structure is Z-shaped, with a positioning protrusion 001 in the middle. Both side walls extend outwards and are not in the same plane. The upper surface of one side is smooth, i.e., the appearance surface 002, while the upper surface of the other side is a functional surface with several positioning structures 003. During molding production, to ensure the quality of the product's appearance surface 002, the sprue is generally located in the middle of the product or on one side of the functional surface. However, since the two ends and the middle of the product are not coplanar, the positioning protrusion 001 in the middle of the product or the side positioning structure 003 may be damaged during demolding, affecting the subsequent assembly quality of the product.

[0025] like Figures 2-3 As shown, the injection structure of the vehicle center console molding die includes a mold base, a fixed mold plate 10, a fixed mold core 20, a moving mold core 30, and a moving mold plate 40. The ends of the fixed mold core 20 and / or the moving mold core 30 are formed with cavities adapted to the product. The injection channel passes through the fixed mold plate 10 and the fixed mold core 20 and is connected to the cavity. The fixed mold core 20 is provided with one or more first inserts 60. The end of each first insert 60 facing the moving mold core 30 is adapted to the product. At least one first insert 60 is formed with one or more branch channels 61 that pass through the first insert 60 along the mold closing direction. One end of each branch channel 61 is connected to the cavity, and the other end is connected to the injection channel through the main channel provided on the fixed mold plate 10.

[0026] The fixed mold base is also provided with one or more second inserts 90 extending along the mold closing direction. Each second insert 90 passes through the fixed mold plate 10 and the fixed mold core 20 in sequence and is slidably connected with them. The end of each second insert 90 is adapted to the product. When the mold is closed, the end of each second insert 90 extends to the side wall of the cavity or extends to its inner side.

[0027] During mold closing, the moving mold first pulls the fixed mold plate 10 under the action of the mold clamping mechanism, causing the fixed mold core 20 to move away from the fixed mold simultaneously, thus completing the first stage of mold closing. This allows the second insert 90, fixed on the fixed mold base, to detach from the product first. Then, under the action of the upper limit mechanism of the fixed mold, the fixed mold base pulls the fixed mold plate 10 and the fixed mold core 20 on it, causing them to detach from the moving mold plate 40, completing the mold closing action. The moving mold core 30 pulls the product, causing it to detach from the fixed mold core 20 and the first insert 60, completing the demolding process. During demolding, the molded structural components on the fixed mold detach from the product one after another, resulting in a smaller pulling force on the product and making it less likely to damage it.

[0028] In plastic molds, a limiting structure is generally provided between the fixed mold platen and the fixed mold base on the fixed mold, and a fastening structure is generally provided between the fixed mold and the moving mold. The two work together to realize the staged mold closing action when the plastic mold is closed. Its working principle is common knowledge to those skilled in the art, and the specific structural settings have been applied in actual production and are described in many patent documents, so they will not be elaborated here.

[0029] For easier and more intuitive understanding, Figure 4 The sprue structure illustrates the injection structure. Each main runner includes a first runner 11 and a second runner 12. Each first runner 11 is located at the end of the fixed mold plate 10 away from the fixed mold core 20. One end of each first runner 11 is connected to the injection runner, and the other end of each first runner 11 intersects with a second runner 12. Each second runner 12 penetrates the fixed mold plate 10 along the mold closing direction. Several second runners 12 are matched and connected to several branch runners 61 one by one. Several second runners 12 are matched and connected to several third runners 21 one by one. Each third runner 21 penetrates the fixed mold core 20 and is connected to the cavity.

[0030] like Figure 4 , 5 As shown, the fixed mold base is also provided with a number of hooks 70 extending along the mold closing direction. The end of each hook 70 is a horn structure 71 with the larger end facing outward. The end of each hook 70 can extend to the connection between a first flow channel 11 and a second flow channel 12 when the mold is closed.

[0031] Understandably, the hook 70 on the fixed mold base facilitates the product's removal from the fixed mold. During the first stage of mold closing, the passive mold plate 30 of the fixed mold plate 10 is pulled away from the fixed mold base, causing the hook 70 fixed on the fixed mold base to leave the fixed mold plate 10. The flared structure 71 at its end, which is smaller at the top and larger at the bottom, breaks off the sprue at the intersection of the first runner 11 and the second runner 12, leaving only the sprue material in the second runner 12 and the branch runner 61 extending along the mold closing direction to contact the product, so that the product can be demolded later.

[0032] like Figure 4 , 6 As shown, each first flow channel 11 is a straight flow channel or a smooth curved flow channel, and each first flow channel 11 is provided with a flow regulating component 80 that can open, close, or regulate the flow rate of the adhesive. In this embodiment, each flow regulating component 80 is a flow-blocking block 81 slidably mounted on the fixed template 10. Each flow-blocking block 81 passes through a first flow channel 11 and its two ends extend to the outside of both sides of the first flow channel 11, and each flow-blocking block 81 is provided with a flow-blocking channel 82 adapted to a first flow channel 11. Each flow-blocking block 81 is provided with a sliding groove 83, and each sliding groove 83 is provided with a fastening screw 84. The fixed template is provided with a plurality of positioning holes and slots that are adapted to the fastening screws 84 one by one.

[0033] It is understandable that the first flow channel 11, which is in the shape of a straight line or a smooth curve, as well as the flow regulating element 80 or the movable intercepting block 81, can be used to regulate the time and rate at which the adhesive enters each branch channel 61, thereby changing the flow rate and direction of the adhesive in the cavity to adapt to different product structure characteristics and avoid or reduce the formation of injection molding defects on the product.

[0034] This invention, by providing a second insert 90 on the fixed mold base and a first insert 60 on the fixed mold core 20, allows the inserts to detach from the product sequentially during mold closing. Each detachment involves a small area, thus preventing or reducing the likelihood of product damage during mold closing. By providing a hook 70 on the fixed mold base, the product can be separated from the fixed mold plate in the first stage of mold closing, facilitating subsequent demolding. By setting several first flow channels 11 and flow regulating components 80 / movable intercepting blocks 81, the flow rate and direction of the adhesive in the cavity can be adjusted to adapt to different product structural characteristics and to avoid or reduce injection molding defects on the product.

[0035] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
