Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to an in-mold compression injection molding mold for industrial control instrument panels. Background Technology

[0002] In the field of industrial control equipment manufacturing, instrument panels, as key appearance and functional components, directly impact the overall performance and user experience of the equipment due to their molding quality. Traditional injection molding of industrial control instrument panels presents numerous challenges due to the need for side convex shaft structures (for assembly and connection), side vertical strip structures (for reinforcement or positioning), and top panel hole structures (for mounting buttons, displays, and other components). Traditional molds typically employ a single-cavity molding method. For lateral protrusions such as side convex shafts and vertical strips, it's difficult to mold them in one step using conventional demolding methods, requiring secondary processing after injection molding, such as manual milling and drilling. Top hole structures require a separate punching process, further increasing the complexity of the production process and increasing the risk of dimensional errors and structural damage due to secondary processing, thus reducing product yield. Furthermore, secondary processing incurs additional labor and equipment costs, extending the production cycle and keeping the production cost of industrial control instrument panels high, making it difficult to meet the efficiency and cost requirements of large-scale industrial production. Furthermore, traditional molds have low cooling efficiency, and uneven cooling of the molded parts after injection molding can easily lead to defects such as warping and shrinkage marks, further affecting product quality stability. Therefore, there is an urgent need to design an in-mold compression injection mold for industrial control instrument panels that can overcome the above defects.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses an injection mold for an automotive dashboard panel [Application No.: 201420387561.7], which includes an upper mold, a lower mold, and a temperature control device. The upper and lower molds are each fixed with a mold core and have several heating chambers. One end of each heating chamber penetrates the side of the upper or lower mold to form an inlet. Several PTC heating elements are arranged within the heating chambers, and each PTC heating element is connected to a conductive wire. The conductive wire passes through the inlet and is electrically connected to the temperature control device to receive temperature information from each PTC heating element and control the temperature of each PTC heating element. The gap between the heating chambers and the PTC heating elements is filled with ceramic powder and metal powder. However, this solution still cannot simultaneously mold the side convex shaft structure, side vertical strip structure, and top panel hole structure required for the dashboard panel during injection molding, still requiring secondary processing and resulting in low production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing an in-mold compression injection molding die for industrial control instrument panels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An in-mold compression injection molding die for an industrial control instrument panel includes a lower instrument panel molding die and an upper instrument panel molding die.

[0009] In the above-mentioned in-mold compression injection molding die for industrial control instrument panel, the panel hole forming part includes a plurality of panel hole forming rods disposed at the bottom of the upper mold for forming the instrument panel, and the side oblique stripping forming rods, the middle oblique stripping forming rods and the panel hole forming rods are arranged alternately.

[0010] In the above-mentioned in-mold compression injection molding die for industrial control instrument panels, the injection molded part includes an injection main board and an injection pressure plate disposed above the upper mold for forming the instrument panel.

[0011] In the above-mentioned in-mold compression injection molding die for industrial control instrument panel, a side fixing frame is provided between the injection main board and the upper mold for forming the instrument panel.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, an in-mold compression injection molding die for an industrial control instrument panel includes a lower instrument panel molding die 1 and an upper instrument panel molding die 2. An injection molded part 3 is provided above the upper instrument panel molding die 2, and a panel molding cavity 4 is provided at the bottom of the upper instrument panel molding die 2. A panel molding protrusion 5 is provided on the lower instrument panel molding die 1, which corresponds to the position of the panel molding cavity 4 and is matched with its shape. A panel hole molding part 6 is provided at the bottom of the upper instrument panel molding die 2. A side oblique ejection auxiliary molding component 7 is provided between the injection molded part 3 and the upper instrument panel molding die 2, extending into the panel molding cavity 4. A straight ejector part 8 is provided below the lower instrument panel molding die 1.

[0026] In this embodiment, when the mold is closed, the lower mold 1 and the upper mold 2 of the instrument panel are closed, and the panel forming protrusion 5 on the lower mold 1 is precisely embedded in the panel forming cavity 4 at the bottom of the upper mold 2, together forming a molding cavity that is consistent with the shape of the industrial control instrument panel; the injection molded part 3 is disposed above the upper mold 2 of the instrument panel and is used to inject molten plastic into the molding cavity; the panel hole forming part 6 is fixed to the bottom of the upper mold 2 of the instrument panel, and its lower end extends into the molding cavity, and is used to form the top hole of the panel; the side oblique ejection auxiliary forming component 7 is installed between the injection molded part 3 and the upper mold 2 of the instrument panel, and its lower end extends through the upper mold 2 of the instrument panel to the side area of ​​the molding cavity, and is used to form the side structure of the panel; the straight ejector part 8 is located below the lower mold 1 of the instrument panel, and its upper end corresponds to the ejection channel in the lower mold 1 of the instrument panel, and is used to eject the plastic part after the mold is opened.

[0027] Combination Figure 1-5As shown, the side oblique ejection auxiliary molding component 7 includes a fixing plate 9 disposed between the injection molded part 3 and the instrument panel molding upper mold 2. Two side oblique ejection molding rods 10 and one middle side oblique ejection molding rod 11 are provided below the fixing plate 9, and the middle side oblique ejection molding rod 11 is located between the two side oblique ejection molding rods 10.

[0028] Specifically, the fixing plate 9 is horizontally installed in the gap between the injection molded part 3 and the upper mold 2 for forming the instrument panel. Its upper and lower surfaces are respectively attached to the bottom of the injection molded part 3 and the top of the upper mold 2 for forming the instrument panel, serving to fix and guide. Two side oblique ejector rods 10 are symmetrically arranged on both sides below the fixing plate 9, and the middle oblique ejector rod 11 is located in the middle of the two side oblique ejector rods 10. The upper ends of all three are slidably connected to the fixing plate 9, and the lower ends extend vertically downward and pass through the upper mold 2 for forming the instrument panel, finally extending into the mold. The corresponding areas on the sides of the cavity, and the positions of the three in the molding cavity correspond one-to-one with the design positions of the two side convex shafts, the central vertical strip and the convex shaft on the side of the instrument panel. The three oblique ejection molding rods are positioned and guided by the fixing plate 9 to ensure that they maintain a stable posture during injection molding and demolding. The positional distribution of the side oblique ejection molding rod 10 and the central oblique ejection molding rod 11 is just right to match the complex structure of different positions on the side of the industrial control instrument panel. It can simultaneously mold the two side convex shafts and the central vertical strip and convex shaft, avoiding the problem of traditional molds requiring multiple molding or secondary processing.

[0029] Combination Figure 1-5 As shown, the side-side oblique stripping forming rod 10 has a panel side-side protruding shaft forming hole 12 on the inner side of its bottom, and the top of the side-side oblique stripping forming rod 10 is slidably connected to the fixing plate 9 through a first connecting slide 13.

[0030] In this embodiment, the side-mounted oblique ejector forming rod 10 is a long strip structure. Its bottom side (i.e., the inner side) facing the center of the forming cavity is recessed inward to form a panel side-mounted convex shaft forming hole 12. The shape and size of this forming hole are completely consistent with the design parameters of the convex shaft on the side of the industrial control instrument panel, ensuring precise forming of the convex shaft. The top of the side-mounted oblique ejector forming rod 10 is fixedly connected to the first connecting slide 13. The outer side of the first connecting slide 13 is provided with a slide rail, and the corresponding position on the fixing plate 9 is provided with a slide groove that matches the slide rail. The first connecting slide 13 can drive the side-mounted oblique ejector forming rod 10 to slide obliquely along the slide groove. The sliding direction (with a preset angle to the mold opening direction) enables lateral release during demolding. The side convex shaft forming hole 12 directly serves as the forming cavity for the convex shaft, forming a complete convex shaft structure without subsequent processing, ensuring the dimensional accuracy and surface finish of the convex shaft. The sliding fit between the first connecting slide 13 and the fixed plate 9 allows the side oblique demolding forming rod 10 to detach along an oblique trajectory during demolding, avoiding collision or scratching with the formed convex shaft, protecting the structural integrity of the convex shaft. At the same time, the stability of the sliding fit ensures the consistency of each demolding action, improving production stability.

[0031] The bottom inner side of the center-side oblique strip forming rod 11 has two panel center-side convex shaft forming holes 14 and panel vertical strip forming grooves 15. The top of the center-side oblique strip forming rod 11 is slidably connected to the fixing plate 9 through the second connecting slide 16.

[0032] In this embodiment, the center-side oblique ejector forming rod 11 is also a long strip structure. Two spaced-apart panel center-side convex shaft forming holes 14 are provided on its bottom inner side (towards the center of the forming cavity). The spacing and size of the two forming holes are consistent with the design requirements of the two convex shafts in the center of the instrument panel. Between the two panel center-side convex shaft forming holes 14, a panel vertical strip forming groove 15 is provided along the length of the center-side oblique ejector forming rod 10. The width and depth of this groove match the dimensions of the panel side vertical strip. The top of the center-side oblique ejector forming rod 11 is fixed to the second connecting slide 16. The structure of the second connecting slide 16 is consistent with that of the first connecting slide 13, and it is also fixed via a slide rail. The sliding fit of the groove on plate 9 can drive the center-side oblique ejection molding rod 11 to slide along a preset oblique trajectory. By integrating the panel center-side convex shaft forming hole 14 and the panel vertical strip forming groove 15 at the bottom of the center-side oblique ejection molding rod 11, the two convex shafts and one vertical strip in the middle of the panel can be formed simultaneously during the injection molding process, realizing the integrated molding of various complex structures and further reducing processing steps. The sliding fit of the second connecting slide 16 ensures that the center-side oblique ejection molding rod 11 is smoothly released when demolding, avoiding damage to the center convex shaft and vertical strip. At the same time, the sliding trajectories of the center-side oblique ejection molding rod 11 and the side-side oblique ejection molding rod 10 are independent of each other and do not interfere with each other, ensuring the coordination of the overall mold movement.

[0033] Combination Figure 2-3 As shown, the panel hole forming component 6 includes a plurality of panel hole forming rods 17 disposed at the bottom of the instrument panel forming upper mold 2, and the side oblique stripping forming rods 10, the middle oblique stripping forming rods 11 and the panel hole forming rods 17 are arranged alternately.

[0034] In this embodiment, the panel hole forming rod 17 is a cylindrical or square rod-shaped structure (selected according to the shape of the panel hole). Its upper end is fixedly connected to the bottom of the instrument panel forming upper mold 2, and its lower end extends vertically downward into the forming cavity. The distribution position and number of the panel hole forming rods 17 completely correspond to the hole design at the top of the industrial control instrument panel. The side oblique stripping forming rod 10 and the middle oblique stripping forming rod 11 are located in the side area of ​​the forming cavity, and the panel hole forming rod 17 are located in the top area of ​​the forming cavity. The three are spatially staggered, that is, the surface... The lower end of the panel hole forming rod 17 does not contact the inclined ejector forming rod, and the sliding trajectory of the inclined ejector forming rod does not interfere with the panel hole forming rod 17, ensuring that each forming action is performed independently. The panel hole forming rod 17 is directly inserted into the forming cavity. During injection molding, the molten plastic surrounds the forming rod to form the hole. After the mold is opened, the hole at the top of the panel can be formed without subsequent punching processing, improving the efficiency and accuracy of hole forming. The staggered structural design of the three avoids interference between the actions of different forming components, ensuring that the side convex shaft, vertical strip and top hole can be formed simultaneously.

[0035] The injection molded part 3 includes an injection molding main plate 18 and an injection molding pressure plate 19 disposed above the instrument panel molding upper mold 2.

[0036] In this embodiment, the injection molding main plate 18 is horizontally covered on the top of the instrument panel molding upper mold 2. It has an injection flow channel inside, the inlet of which is connected to the outlet of the external injection molding machine, and the outlet corresponds to the feed channel on the instrument panel molding upper mold 2, which is used to transport the molten plastic to the molding cavity. The injection pressure plate 19 is located above the injection molding main plate 18. Its size matches the injection molding main plate 18 and is connected to the external pressure device. It can apply downward pressure during the injection process to push the injection molding main plate 18 to fit tightly with the instrument panel molding upper mold 2, and at the same time apply compressive force to the molten plastic to ensure that the plastic fully fills the molding cavity.

[0037] A side fixing frame 20 is provided between the injection molding main board 18 and the instrument panel molding upper mold 2. One end of the fixing plate 9 abuts against the injection molding pressure plate 19, and the other end abuts against the side fixing frame 20.

[0038] In this embodiment, the side fixing frame 20 not only achieves a sealed connection between the injection molding main board 18 and the instrument panel molding upper mold 2 to prevent molten plastic leakage, but also provides stable support for the fixing plate 9. The fixing plate 9 is fixed by the abutment of both ends to ensure that it remains stable in position during the mold operation, thereby ensuring the molding accuracy of the side oblique ejection molding rod 10 and the middle oblique ejection molding rod 11, avoiding the misalignment of the plastic part structure caused by the offset of the fixing plate 9. At the same time, this fixing method does not require additional fasteners, simplifies the assembly process, and facilitates mold maintenance.

[0039] Combination Figure 5As shown, the straight ejector demolding component 8 includes an ejector pin fixing plate 21 disposed below the instrument panel forming lower mold 1, and the ejector pin fixing plate 21 is provided with a plurality of straight ejector demolding pins 22.

[0040] In this embodiment, the ejector pin fixing plate 21 provides a unified mounting and driving base for the straight ejector pins 22, ensuring that all ejector pins move synchronously; the several straight ejector pins 22 are evenly distributed, which can apply a uniform ejection force to the panel, avoiding excessive local force that could cause panel deformation or damage, and is especially suitable for thin and easily deformable plastic parts such as industrial control instrument panels; the straight ejection method has a simple structure and reliable operation, and compared with the complex side ejection mechanism, it has a lower failure rate and lower maintenance cost, while also having high ejection efficiency, which can shorten the production cycle.

[0041] Combination Figure 1 , Figure 5 As shown, a bottom base plate 23 is provided below the top rod fixing plate 21, and two anti-deviation irons 24 are provided on the bottom base plate 23. The top rod fixing plate 21 and the anti-deviation irons 24 are slidably engaged.

[0042] In this embodiment, the bottom base plate 23 is the bottom support structure of the mold, which is fixedly connected to the ground or the injection molding machine workbench to stabilize the entire mold; the two anti-deviation irons 24 are long strip-shaped metal parts, which are symmetrically fixed on both sides of the top of the bottom base plate 23, and have vertical guide grooves on their inner sides; the two sides of the push rod fixing plate 21 are provided with guide blocks that match the guide grooves, and the guide blocks are embedded in the guide grooves, so that the push rod fixing plate 21 can slide vertically up and down along the guide grooves of the anti-deviation irons 24, and cannot deviate in the horizontal direction.

[0043] Combination Figure 1 As shown, the lower mold 1 and the upper mold 2 for forming the instrument panel have cooling channels 25.

[0044] In this embodiment, after injection molding is completed, cooling water is injected into the cooling water channel 25 to cool the molded plastic part, resulting in high molding quality.

[0045] The working principle of this utility model is as follows: An external injection molding machine delivers molten plastic to the injection main plate 18 of the injection molded part 3. The molten plastic flows through the flow channel of the injection main plate 18 and the feed channel of the upper mold 2 of the instrument panel forming mold, into the micro-gap between the lower mold 1 and the upper mold 2 of the instrument panel forming mold, and gradually fills the molding cavity formed by the panel forming cavity 4 and the panel forming protrusion 5. During this process, the injection pressure plate 19 applies a preset pressure downward under the drive of the external pressure device: on the one hand, the pressure pushes the injection main plate 18 and the upper mold 2 of the instrument panel forming mold to fit tightly together, preventing the molten plastic from leaking from the mold gap; on the other hand, the pressure forces the molten plastic to flow fully in the molding cavity, not only filling the main space of the cavity, but also accurately flowing into the side slope. The panel side convex shaft forming hole 12 of the ejector rod 10 (forming a side convex shaft), the panel center side convex shaft forming hole 14 of the center oblique ejector rod 11 (forming a center convex shaft), and the panel vertical strip forming groove 15 (forming a side vertical strip) simultaneously fill around the panel hole forming rod 17 (forming a top hole), achieving synchronous forming of all complex structures of the panel. This "in-mold compression" process at this stage can significantly reduce the plastic flow resistance compared to traditional injection molding, avoid defects such as material shortage and air bubbles, and ensure the density and structural integrity of the plastic part. After the molten plastic completely fills the molding cavity and completes the structural forming, the mold enters the cooling and solidification stage: cooling medium is continuously introduced into the cooling channel 25, and the heat of the mold and plastic part is carried away through heat exchange. During demolding, the external drive device transmits power through the fixed plate 9, causing the first connecting slide 13 to drive the side oblique demolding rod 10 and the second connecting slide 16 to drive the middle oblique demolding rod 11, which slide obliquely along the groove on the fixed plate 9. Since the side oblique demolding rod 10 and the middle oblique demolding rod 11 are "embedded" with the convex shaft and vertical strip structure on the side of the plastic part, the oblique sliding can gradually separate the molding hole / groove from the side structure of the plastic part, avoiding structural interference during traditional vertical demolding, protecting the integrity of the side convex shaft and vertical strip, and ensuring no wear on the molding parts. After the side oblique demolding rod 10 and the middle oblique demolding rod 11 complete the oblique separation, the external drive device pushes the straight demolding part. The ejector plate 21 of the 8 moves vertically upward along the guide groove of the anti-deviation iron 24 on the bottom base plate 23. The ejector plate 21 drives several straight ejector rods 22 to rise synchronously. The top of the straight ejector rods 22 passes through the ejection channel of the instrument panel forming lower mold 1 and applies a uniform ejection force to the bottom of the plastic part, lifting the plastic part from the panel forming protrusion 5 and separating it from the instrument panel forming lower mold 1. When the straight ejector rods 22 push the plastic part to the preset height, the external part removal device (such as a robotic arm) removes the formed industrial control instrument panel, completing one molding cycle. Subsequently, all parts of the mold are reset (the side oblique ejector rod returns to its original position, the straight ejector part returns to its original position, and the mold closes), entering the next molding cycle.
