Description

Technical Field

[0001] This application relates to the field of mold demolding technology, and in particular to a strong demolding structure combining a large mold inclined ejector and a pull block. Background Technology

[0002] The sub-instrument panel is the mounting platform for various control components in modern automobiles and a crucial component in automotive manufacturing. Also known as the center console or center tunnel, it is a longitudinal component located between the driver and passenger seats, connecting the instrument panel (front center console) and the rear seat area; it is not merely an armrest box, but a functionally integrated area.

[0003] With the rapid development of the automotive industry, product quality requirements are getting higher and higher, new processes are constantly emerging, and structures are becoming more and more complex. Due to structural requirements, multiple mounting points need to be set on the side wall, resulting in a particularly large undercut area and demolding stroke. If a conventional mold structure is used, demolding will be difficult and normal demolding and forming will not be possible.

[0004] Reference Figure 1 The diagram shows a product model. Product 1 includes an upper side panel 11 and side panels 12 arranged on both sides of the upper side panel 11. Numerous fixing buckles 13 are arranged on the inner side of the side panels 12, and these fixing buckles 13 have a relatively large area. After injection molding, these fixing buckles 13 will be molded and limited within the mold. Therefore, due to the limitation provided by the fixing buckles 13, the molded product 1 cannot be ejected from the mold using a traditional angled ejector method. Summary of the Invention

[0005] To improve the demolding efficiency of the sub-instrument panel, this application provides a large mold inclined ejector and pull block combination strong demolding structure.

[0006] This application provides a combined inclined ejector and pull block structure for strong release in a large mold, employing the following technical solution: A large mold inclined ejector and pull block combined strong release structure includes a core seat frame, a core insert arranged on the core seat frame for product forming, a pull-out assembly arranged on both sides of the core seat frame, and an inclined ejector assembly arranged on the core seat frame for inclined lifting of the product. The pull-out assembly includes a large slider slidably arranged on the core seat frame, a pull block arranged on the core insert and abutting against the large slider, and a hydraulic cylinder for driving the large slider to slide on the core seat frame. The large slider is provided with a barb at the abutting point with the pull block, and the pull block is provided with a protrusion that limits the barb. The large slider moves away from the core insert and drives the pull block to demold the two sides of the product from the core insert. The inclined ejector assembly includes a large inclined ejector arranged within the core insert for product demolding, an inclined ejector rod arranged within the core frame for lifting the large inclined ejector, and a lifting component for driving the inclined ejector rod.

[0007] By adopting the above technical solution, the core insert on the core seat frame realizes product molding. The large slider in the pull assembly slides on the core seat frame under the drive of the hydraulic cylinder. The large slider cooperates with the protrusion of the pull block through the barb, and drives the pull block to demold the two sides of the product from the core insert. The inclined ejector assembly drives the inclined ejector rod to move through the lifting component, and lifts the large inclined ejector to demold the product at an angle. This realizes strong demolding by combining the inclined ejector and the pull block of the large mold, and improves the demolding efficiency and quality of the product.

[0008] Optionally, the large slider is provided with a positioning boss that is wedged into the core insert, the core seat frame is provided with a guide bar for the large slider to slide, and the core seat frame is also provided with a pressure block slide bar, which is arranged on both sides of the large slider.

[0009] By adopting the above technical solutions, the positioning boss wedged into the core insert can improve the matching accuracy and stability of the large slider and the core insert; the guide bar provides guidance for the large slider to slide on the core seat frame, making the movement of the large slider more precise; the pressure block slide bar arranged on both sides of the large slider can limit the displacement of the large slider in the non-sliding direction, ensure the smooth sliding of the large slider, and thus ensure the stable operation of the entire strong demolding structure, so as to achieve smooth demolding of the product.

[0010] Optionally, the pull block includes a vertical portion arranged within the core insert and a horizontal portion arranged within the core seat frame, wherein the vertical portion and the large slider form a mold cavity, and the product is formed within the mold cavity.

[0011] By adopting the above technical solution, the pull block is provided with a vertical part and a horizontal part, and the vertical part and the large slider form a mold cavity, which allows the product to be formed in the cavity, providing a specific space for product forming and ensuring that the product is formed according to the design requirements.

[0012] Optionally, the horizontal part is provided with a movable part for the barb to move, and a spring connecting rod is provided at the end of the horizontal part, the spring connecting rod being arranged inside the core seat frame.

[0013] By adopting the above technical solution, the large slider moves away from the core insert, driving the pull block to demold the product from both sides of the core insert. The inclined ejector rod in the inclined ejector assembly lifts the large inclined ejector for product demolding. The horizontal part of the pull block is provided with a movable part for the hook to move, which allows the hook to move within the movable part, ensuring the flexibility of the cooperation between the large slider and the pull block. The spring connecting rod arranged at the end of the horizontal part in the core seat frame can provide buffering and reset during the demolding process, assisting the product to be demolded smoothly.

[0014] Optionally, the spring connecting rod has a first connecting rod arranged within the core seat frame, a second connecting rod arranged on the side of the first connecting rod facing the core insert, the diameter of the first connecting rod being larger than the diameter of the second connecting rod, and a first spring arranged circumferentially on the second connecting rod.

[0015] By adopting the above technical solution, the spring connecting rod is equipped with a first link and a second link, with the diameter of the first link being larger than that of the second link. This can provide a stable connection and guidance between the core seat frame and the core insert. The first spring arranged circumferentially on the second link can provide elastic buffering force, ensuring that the pull block moves smoothly during demolding, avoiding rigid collisions that could damage the mold and the product, and improving the service life of the mold and the quality of the product molding.

[0016] Optionally, a first cavity for the spring connecting rod to move is arranged on the horizontal part, and a second cavity for the second connecting rod to move is arranged on the side of the first cavity; the diameter of the first cavity is larger than that of the second cavity, the diameter of the first cavity is larger than that of the spring connecting rod, and the diameter of the second cavity is larger than that of the second connecting rod; the first cavity, the second cavity, and the spring connecting rod are arranged coaxially.

[0017] By adopting the above technical solution, the spring connecting rod has a first link and a second link with different diameters, and the first spring is arranged circumferentially on the second link; with the first cavity and the second cavity on the horizontal part that are adapted to the spring connecting rod and the second link and are arranged coaxially, the spring connecting rod can move smoothly in the horizontal part, making the spring extension and contraction process stable, thereby ensuring the movement stability and reliability of the pull block during the demolding process, which helps the product to be demolded smoothly from the core insert.

[0018] Optionally, the lifting component includes a horizontal plate slidably arranged within the core frame, a universal slide seat arranged on the horizontal plate and hinged to the inclined push rod, and an ejection cylinder arranged on the side of the horizontal plate, wherein the inclined push rod is inclinedly arranged within the core frame.

[0019] By adopting the above technical solution, a horizontal plate is slidably arranged in the core frame, a universal slide is arranged on the horizontal plate and hinged to the inclined ejector rod, and an ejector cylinder is arranged on the side of the horizontal plate. The inclined ejector rod is inclinedly arranged in the core frame. The ejector cylinder can drive the horizontal plate to slide in the core frame, and then drive the inclined ejector rod to move through the universal slide, so as to realize the lifting of the large inclined ejector rod and complete the inclined demolding of the product.

[0020] Optionally, the core frame is provided with a sliding guide rail on its side, the ejector cylinder is fixedly arranged in the sliding guide rail, the cross plate is provided with a side block, the side block is slidably arranged in the sliding guide rail and is connected and fixed to the ejector cylinder.

[0021] By adopting the above technical solution, the sliding guide rail on the side of the core seat frame fixes the ejector cylinder in it, and the side block of the horizontal plate can also slide in the sliding guide rail and be connected and fixed to the ejector cylinder. This allows the horizontal plate of the lifting component to slide stably in the core seat frame, ensuring that the lifting action of the inclined ejector is smooth and reliable, thereby enabling the large inclined ejector to successfully lift the product for demolding.

[0022] Optionally, the hydraulic cylinder is fixedly arranged on the core seat frame, and a cylinder connecting block is arranged on the large slider. The output end of the hydraulic cylinder is fixedly connected to the cylinder connecting block.

[0023] By adopting the above technical solution, the hydraulic cylinder is fixed on the core seat frame, and its output end is fixedly connected to the cylinder connecting block on the large slider. This enables the hydraulic cylinder to stably drive the large slider to slide on the core seat frame, thereby realizing the demolding of the product from both sides of the core insert.

[0024] Optionally, a limit switch is arranged on the core frame, and a lever is arranged on the large slider to contact the limit switch. When the lever moves to a set position, it triggers a feedback signal from the limit switch and stops the hydraulic cylinder.

[0025] By adopting the above technical solution, the limit switch on the core frame and the lever on the large slider can trigger the limit switch when the lever moves with the large slider to the set position, so that the limit switch feeds back a signal and stops the hydraulic cylinder, thereby achieving precise control of the movement stroke of the large slider, avoiding excessive movement of the large slider, and ensuring the stability and accuracy of the product demolding process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining the pull-out assembly and the angled ejector assembly, the pull-out assembly is responsible for demolding the product from both sides, while the angled ejector assembly lifts the product from the angle. The two work together to ensure that the product can be completely and smoothly ejected from the mold, which greatly improves demolding efficiency and product quality. 2. The large slider and the pull block have a tight fit between their barbs and protrusions. When the hydraulic cylinder drives the large slider to move, this fit can accurately demold the product from both sides of the core insert. Compared with the traditional method, this can effectively avoid the product from getting stuck or damaged in some areas, ensuring that the product's appearance and performance are not affected, and improving the product's pass rate. 3. The large angled ejector, angled ejector rod, and lifting components of the angled ejector assembly work together to lift the product at an angle. During the demolding process of large molded and complex products, the angled lifting can provide additional demolding force, make up for the deficiencies of other components, further assist in product demolding, and fully meet the strong demolding requirements of large molded and complex products.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a combined strong release structure of a large mold with an inclined ejector and a pull block. Example 1:

[0037] Reference Figure 2 and Figure 3As shown, a large mold with a combination of inclined ejector and pull block for strong demolding includes a core frame 2, a core insert 3, a pull-out assembly 4, and an inclined ejector assembly 5. The core insert 3 is arranged on the core frame 2 for molding the product 1. The pull-out assembly 4 is arranged on both sides of the core frame 2 to demold the product 1 from both sides of the core insert 3. The inclined ejector assembly 5 is arranged on the core frame 2 and is used to lift the product 1 at an angle. This combination structure allows the large mold to demold both sides of the product 1 through the pull-out assembly 4 and to lift it at an angle through the inclined ejector assembly 5. This effectively solves the limitations of demolding with a single structure and can meet the demolding requirements of large products 1 with complex shapes, lateral demolding needs, and undercuts or lateral protrusions.

[0038] Reference Figure 3 and Figure 4 As shown, the pull-out assembly 4 includes a large slider 41 slidably arranged on the core holder 2, a pull block 42 arranged on the core insert 3 and abutting against the large slider 41, and a hydraulic cylinder 43 driving the large slider 41 to slide on the core holder 2. The large slider 41 is arranged on both sides of the core insert 3 and is made of high-strength alloy to ensure it can withstand injection molding pressure. The pull block 42 slides on the core holder 2 via the large slider 41. The pull block 42 is made of the same high-strength alloy material as the large slider 41 to ensure the strength and wear resistance of the contact area between the pull block 42 and the large slider 41.

[0039] Reference Figure 4 and Figure 5 As shown, the large slider 41 is provided with a positioning boss 412 that wedges into the core insert 3. The positioning boss 412 is located on the bottom side of the large slider 41 facing the core insert 3, and the core insert 3 is provided with a positioning groove for the positioning boss 412. When the large slider 41 slides, it weds the positioning boss 412 into the positioning groove. The positioning boss 412 and the positioning groove achieve mutual positioning between the large slider 41 and the core insert 3, avoiding deviation between the large slider 41 and the core insert 3 that would cause changes in the dimensions of the final product 1. The core frame 2 is provided with a guide bar 21 for the large slider 41 to slide. The guide bar 21 is fixed to the core frame 2 with bolts, ensuring the stability of the guide bar 21 as it slides on the core frame 2. The core frame 2 is also provided with pressure block slides 22, which are arranged on both sides of the large slider 41. The pressure block slides 22 can prevent the large slider 41 from shaking or shifting during the sliding process. The pressure block slides 22 are connected to the core frame 2 by bolts.

[0040] Hydraulic cylinder 43 drives large slider 41 to slide on core frame 2. Hydraulic cylinder 43 is fixedly arranged on core frame 2. Large slider 41 is equipped with a cylinder connecting block 414 fixed to hydraulic cylinder 43. The output end of hydraulic cylinder 43 is fixedly connected to cylinder connecting block 414, ensuring that hydraulic cylinder 43 can stably drive large slider 41 to slide on core frame 2. The model of hydraulic cylinder 43 can be set according to the weight of large slider 41 and the actual required pressure.

[0041] Reference Figure 6 and Figure 7 As shown, the pull block 42 includes a vertical portion 421 arranged within the core insert 3 and a horizontal portion 422 arranged within the core frame 2. The vertical portion 421 and the horizontal portion 422 are manufactured as a single piece to ensure the overall strength of the pull block 42. The vertical portion 421 is wedged into the core insert 3, and a mold cavity 4211 is formed between the wedged core insert 3 and the large slider 41. The product 1 is formed within the mold cavity 4211. A movable portion 4221 is arranged on the horizontal portion 422, and a barb 411 is arranged on the large slider 41 that moves within the movable portion 4221. A protrusion 423 with a limiting barb 411 is also arranged on the horizontal portion 422. When the large slider 41 slides, the barb 411 on the large slider 41 abuts against the protrusion 423, causing the pull block 42 to move simultaneously with the large slider 41. The vertical part 421 of the pull block 42 disengages from the core insert 3, detaching the side plate 12 of the molded product 1 from the core insert 3. At the same time, the arrangement of the pull block 42 matches the position of the fixing buckle 13 on the inner side of the side plate 12 of the product 1. The movement of the pull block 42 detaches the fixing buckle 13 from the core insert 3. Since the injection-molded product 1 is a plastic product, its material itself has a certain degree of flexibility. Therefore, the deformation of the product 1 caused by the pull block 42 during demolding is controllable and will not damage the product 1. Then, the inclined ejector assembly 5 lifts the entire product 1, realizing the demolding of the entire product 1 from the core insert 3.

[0042] Reference Figure 7As shown, a spring connecting rod 23 is arranged at the end of the horizontal part 422, and the spring connecting rod 23 is arranged inside the core seat frame 2. The spring connecting rod 23 has a first connecting rod 231 arranged inside the core seat frame 2, and a second connecting rod 232 arranged on the side of the first connecting rod 231 facing the core insert 3. The diameter of the first connecting rod 231 is larger than the diameter of the second connecting rod 232, and a first spring 233 is arranged circumferentially on the second connecting rod 232. The function of the first spring 233 is to enable the pull block 42 to automatically return to its original position under the force of the first spring 233 after demolding. A first cavity 4222 for the spring connecting rod 23 to move is arranged on the horizontal part 422. A second cavity 4223 for the second connecting rod 232 to move is arranged on the side of the first cavity 4222. The diameter of the first cavity 4222 is larger than that of the second cavity 4223, the diameter of the first cavity 4222 is larger than that of the spring connecting rod 23, and the diameter of the second cavity 4223 is larger than that of the second connecting rod 232. The first cavity 4222, the second cavity 4223 and the spring connecting rod 23 are arranged coaxially to ensure that the spring connecting rod 23 will not get stuck during the movement, and also to make the movement of the spring connecting rod 23 smoother.

[0043] Driven by the hydraulic cylinder 43, the large slider 41 moves outward along the guide bar 21. At this time, the barb 411 on the large slider 41 moves within the movable part 4221 of the horizontal part 422, so the sliding of the large slider 41 will not cause the pull block 42 to move. At this time, the large slider 41 moves away from the core insert 3, realizing the demolding of the large slider 41 and the molded product 1. At this time, the pull block 42 is supported by the spring connecting rod 23 and the movement of the large slider 41 does not affect the pull block 42, so the pull block 42 is stationary. When the barb 411 of the large slider 41 slides to the protrusion 423, the large slider 41 continues to slide and will abut against the protrusion 423 through the barb 411, causing the pull block 42 to move in the sliding direction of the large slider 41. When the pull block 42 moves, it compresses the first spring 233 on the spring connecting rod 23. Simultaneously, the second connecting rod 232 moves into the second cavity 4223 along with the pull block 42. The end of the second connecting rod 232 abuts against the inner end of the second cavity 4223, indicating that the pull block 42 has moved to the set position. When the pull rod moves, the vertical part 421 disengages from the core insert 3, and at the same time, the fixing buckle 13 on the inner side of the side plate 12 of the product 1 disengages from the core insert 3, solving the problem of difficulty in demolding the fixing buckle 13 of the side plate 12 from the core insert 3 in the prior art. When the large slider 41 moves toward the core insert 3, the hook 411 moves away from the protrusion 423, reducing the pulling force on the protrusion 423. Therefore, the elastic force generated by the first spring 233 on the spring connecting rod 23 drives the pull block 42 to move toward the core insert 3, and the pull block 42 returns to the core insert 3.

[0044] Reference Figure 5As shown, the inclined ejector assembly 5 includes a large inclined ejector 51 arranged within the core insert 3 for demolding product 1, an inclined ejector rod 52 arranged within the core seat frame 2 for lifting the large inclined ejector 51, and a lifting component 53 for driving the inclined ejector rod 52. The large inclined ejector 51 is inclined within the core insert 3, and a sliding cavity is provided within the core insert 3 for the large inclined ejector 51 to move. The large inclined ejector 51 lifts within the sliding cavity to lift the upper side panel 11 of the molded product 1 away from the core insert 3. The inclined ejector rod 52 is inclined within the core seat frame 2, and the inclination angle of the inclined ejector rod 52 can be adjusted according to the demolding requirements of product 1.

[0045] Reference Figure 3 and Figure 4 As shown, the lifting component 53 includes a horizontal plate 531 slidably arranged within the core frame 2, a universal slide 532 arranged on the horizontal plate 531 and hinged to the inclined jack 52, and an ejection cylinder 533 arranged on the side of the horizontal plate 531. A sliding guide rail 24 is arranged on the side of the core frame 2, and the ejection cylinder 533 is arranged within the sliding guide rail 24. A side block 5311 is arranged on the side of the horizontal plate 531, and the side block 5311 slides within the sliding guide rail 24 and is fixedly connected to the output end of the ejection cylinder 533. The horizontal plate 531 is raised and lowered by the ejection cylinder 533. The universal slide 532 allows the inclined jack 52 to move flexibly during the lifting process and better achieves the lifting of the large inclined jack 51.

[0046] Reference Figure 2 and Figure 3 As shown, a limit switch 25 is also arranged on the core frame 2, and a lever 415 that contacts the limit switch 25 is arranged on the large slider 41. When the lever 415 slides along the large slider 41 and touches the limit switch 25, the limit switch 25 sends a signal to the control center of the injection molding machine, and the control center sends a feedback signal to stop the hydraulic cylinder 43. The lever 415 can be fixed to the large slider 41 by welding. At the same time, cooling water pipes are also arranged on the core frame 2.

[0047] A wear-resistant plate 413 is arranged on the side of the large slider 41 away from the core insert 3. During injection molding, the mold cavity presses against the wear-resistant plate 413 on the back of the large slider 41.

[0048] The implementation principle of the large mold inclined ejector and pull block combination strong demolding structure in this application embodiment is as follows: the large mold inclined ejector and pull block 42 combination strong demolding structure realizes the simultaneous demolding of the large mold product 1 in multiple directions and angles through the synergistic action of the pull assembly 4 and the inclined ejector assembly 5. The hydraulic cylinder 43 in the pull assembly 4 drives the large slider 41 to move, and through the cooperation of the barb 411 and the protrusion 423, it drives the pull block 42 to demold the two sides of the product 1 from the core insert 3; the ejection cylinder 533 in the inclined ejector assembly 5 drives the horizontal plate 531 to move, and through the universal slide 532 and the inclined ejector rod 52, it lifts the large inclined ejector 51, thereby realizing the inclined demolding of the product 1.

[0049] This combined structure can effectively cope with the demolding requirements of large molds with complex structures and multiple undercuts, avoiding problems such as tearing and deformation of product 1 during demolding, improving the surface quality and dimensional accuracy of product 1, and also improving demolding efficiency, thus meeting the requirements of high-efficiency production. Example 2:

[0050] In this embodiment, the lifting component 53 uses a screw and nut mechanism instead of the ejector cylinder 533. The screw and nut mechanism includes a screw and a nut that cooperates with the screw. The screw is rotatably arranged on the core seat frame 2, and the nut is fixedly connected to the horizontal plate 531. The screw is connected to a drive motor. The drive motor drives the screw to rotate, and the rotation of the screw causes the nut to move linearly along the screw, thereby realizing the movement of the horizontal plate 531, and then lifting the large inclined jack 51 through the universal slide 532 and the inclined jack rod 52.

[0051] The implementation principle of this embodiment is as follows: the use of a screw and nut mechanism can more precisely control the lifting displacement and speed of the inclined ejector rod 52, which can better guarantee the quality of large mold products 1 that have high requirements for demolding accuracy. At the same time, compared with hydraulic cylinder drive, the screw and nut mechanism has a more compact structure, occupies less space, is conducive to the miniaturization design of molds, and has less noise during operation and is relatively simple to maintain, thus improving the overall performance and applicability of the mold.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
