Description

Technical Field

[0001] This utility model relates to the field of mold ejection technology, and in particular to a height-adjustable conformal ejection mechanism. Background Technology

[0002] In precision manufacturing fields such as injection molding and die casting, the ejection mechanism, as a core component of the mold system, primarily functions to smoothly and completely detach the solidified workpiece from the mold cavity or core surface after molding. This directly determines the workpiece's molding quality, production efficiency, and the mold's lifespan. As the manufacturing industry moves towards high-end and personalized products, product structures are becoming increasingly complex. The demand for workpieces with non-planar ejection surfaces, such as curved shells, irregularly shaped supports, and multi-step thin-walled parts, is surging, posing unprecedented challenges to the adaptability and precision of the ejection mechanism.

[0003] The initial installation height or maximum ejection stroke of existing ejector pins are mostly fixed. When dealing with workpieces with complex curved surfaces or varying thicknesses, it is often difficult to achieve precise fit and stable support, thus making it difficult to adapt to different working conditions. Utility Model Content

[0008] As a further embodiment of this utility model, both sets of mold plates are provided with sliding grooves inside, and both sets of ejector plates are slidably connected inside the sliding grooves. The sliding grooves enable the ejector plates to slide.

[0014] (III) Beneficial Effects

[0015] This utility model provides a height-adjustable conformal ejection mechanism, which has the following beneficial effects:

[0016] 1. This height-adjustable conformal ejection mechanism, through the setting of the ejection component, when the upper mold and lower mold are separated, the compression spring drives the ejection plate to move, and the ejection plate ejects the produced mold from inside the lower mold. When facing molds of different shapes, rotating the adjusting rod causes the adjusting rod to engage and rotate in the threaded hole of the ejection plate. Through threaded transmission, the rotational motion is converted into axial displacement, thereby precisely adjusting the initial installation height or maximum ejection stroke of the ejection plate. This allows the ejection plate to adapt to molded workpieces of different thicknesses and structures, effectively improving the versatility and adaptability of the mechanism, and ensuring that all types of workpieces can achieve a smooth and efficient demolding effect.

[0017] 2. This height-adjustable conformal ejection mechanism, through the setting of the snap-fit ​​component, allows for easy operation when the rotary valve is rotated. The rotation of the rotary valve drives the threaded rod to rotate, which in turn moves the sliding plate on the fixed frame. The movement of the sliding plate moves the snap-fit ​​rod, which is then pulled out from inside the mold plate, releasing the mold plate from its limiting position. The mold plate is no longer constrained by the snap-fit ​​rod, allowing workers to easily remove the mold plate without the need for complex tools, thus achieving rapid disassembly of the mold plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Example 1

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a height-adjustable conformal ejection mechanism, including a lower mold 1, with several sets of limiting grooves on both sides of the lower mold 1 and the upper mold 2, and several sets of snap-fit ​​rods 303 inserted into the limiting grooves. Guide blocks 6 are fixedly connected to the top surface of the lower mold 1 around its perimeter, and four sets of guide grooves are provided on the bottom surface of the upper mold 2. A mold block 7 is provided on the right side of the top surface of the lower mold 1. Positioning plates 8 are fixedly connected to both sides of the lower mold 1. Several sets of flow guide holes are provided on both sides of the lower mold 1 and the upper mold 2. Cooling grooves are provided inside the upper mold 1 and the lower mold 2. The upper mold 2 is overlapped and connected to the top surface of the lower mold 1. Snap-fit ​​components 3 are fixedly connected to both sides of the lower mold 1 and the upper mold 2. Mold plates 4 are snap-fitted and connected inside the upper mold 1 and the lower mold 2. Each of the mold plates 4 has a sliding groove inside. Both sets of ejector plates 501 are slidably connected inside the sliding groove. Ejector components 5 are slidably connected inside the mold plates 4. Each of the four sets of snap-fit ​​components 3 includes a fixing frame 301 fixedly connected to both sides of the lower mold 1 and the upper mold 2. Each of the four fixing frames 301 has a sliding plate 302 slidably connected inside. Each of the four sliding plates 302 has two snap-fit ​​rods 303 fixedly connected to one side. Each of the four sliding plates 302 has a threaded rod 304 rotatably connected to the other side. Each of the four threaded rods 304 has a rotary valve 305 fixedly connected to one end. Each of the two sets of ejector components 5 includes an ejector plate 501 slidably connected inside the mold plate 4. Each of the two sets of ejector plates 501 has an adjusting rod 502 threadedly connected inside. Each of the two adjusting rods 502 has a compression spring 503 sleeved on the outside.

[0026] Furthermore, the mold groove inside the mold block 7 is used to shape the injection liquid, so that the device can produce the required mold. The positioning plate 8 is used to position the device, and the positioning bolt 9 is used to fix the lower mold 1 so that the device can be fixed in the required position.

[0027] In this invention, the working steps of the device are as follows:

[0028] First step: When the upper mold 2 separates from the lower mold 1, the compression spring 503 drives the ejector plate 501 to move. The ejector plate 501 ejects the produced mold from the inside of the lower mold 1. When facing molds of different shapes, the adjusting rod 502 is rotated. The adjusting rod 502 rotates in the threaded hole of the ejector plate 501. The rotational motion is converted into axial displacement through thread transmission, thereby precisely adjusting the initial installation height or maximum ejection stroke of the ejector plate 501. This allows the ejector plate 501 to adapt to molded workpieces of different thicknesses and structures, thereby effectively improving the versatility and adaptability of the mechanism and ensuring that all kinds of workpieces can achieve a smooth and efficient demolding effect.

[0029] The second step: During use, rotating the rotary valve 305 causes the threaded rod 304 to rotate, which in turn moves the sliding plate 302 on the fixed frame 301. The movement of the sliding plate 302 then moves the locking rod 303, which is pulled out from inside the mold plate 4, releasing the limiting effect on the mold plate 4. The mold plate 4 is no longer constrained by the locking rod 303, allowing workers to easily remove it without complex tools, thus achieving rapid disassembly.
