Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold with a rotating ejection mechanism. Background Technology

[0002] Molds are key tools used in industrial production to shape parts, and their design directly affects product quality and production efficiency. For example... Figure 1 The breast pump shown has a connected horizontal channel 401 and a vertical channel 402, with a horizontally inclined guide ramp 403 at the connection point. The opening directions of the horizontal channel 401 and the vertical channel 402 are inconsistent, and the guide ramp 403 is positioned below the bottom of the horizontal channel 401, preventing the guide ramp 403 from being molded and pulled synchronously with the horizontal channel 401. Simultaneously, the vertical channel 402 is relatively narrow, causing the guide ramp 403 to easily interfere with the vertical channel 402 during ejection and demolding, affecting the normal opening and closing of the mold and the smooth demolding of the product, potentially resulting in defective products. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mold with a rotating ejection mechanism, which achieves molding and demolding in a small space through rotation, resulting in a simple and convenient structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A mold with a rotating ejection mechanism includes: a front mold assembly, a rear mold assembly disposed below the front mold assembly, an ejection assembly disposed below the rear mold assembly, a base plate disposed below the ejection assembly, a side core-pulling mechanism for forming a transverse channel disposed on the front mold assembly, and a rotating ejection mechanism disposed on the rear mold assembly and connected to the ejection assembly.

[0006] The rotating ejection mechanism includes an ejection structure for forming a vertical channel and a rotating structure disposed on the ejection structure for forming a guide slope; during demolding, the ejection assembly can drive the rotating structure to eject upwards for demolding, and at the same time drive the rotating structure to rotate for demolding.

[0007] According to some embodiments of the present invention, the rotating structure includes a fixed seat disposed on the top of the ejection structure and a rotatable rotating block disposed on the fixed seat. The rotating block includes a forming part for forming the guide slope and a rotating part for rotating.

[0008] According to some embodiments of the present invention, the rotating part includes a connecting block and a rotating shaft disposed at the end of the connecting block. The fixed seat is provided with a first groove that cooperates with the connecting block. When the rotating block rotates, the connecting block can slide relative to the first groove.

[0009] According to some embodiments of the present invention, the rotating shaft is disposed below the first groove, and the length of the rotating shaft is greater than the width of the first groove.

[0010] According to some embodiments of the present invention, the top of the ejector structure is provided with a second groove that cooperates with the rotating shaft, and the rotating shaft can rotate within the second groove.

[0011] According to some embodiments of the present invention, the rotating structure includes a positioning structure disposed on one side of the rotating part for positioning the forming part.

[0012] According to some embodiments of the present invention, the positioning structure includes a positioning block disposed on the top of the ejection structure, and the bottom of the rotating part has a positioning groove that cooperates with the positioning block. When the rotating block is reset, the positioning block can be inserted into the positioning groove.

[0013] According to some embodiments of the present invention, the ejection structure includes a forming rod and a push tube sleeved on the outside of the forming rod; the bottom of the forming rod is connected to the base plate; the bottom of the push tube is connected to the ejection assembly; the rotating ejection mechanism is disposed on the top of the forming rod; during demolding, the ejection assembly can push the push tube upward to drive the molded part to be lifted upward, and the rotating structure can be lifted by the molded part and flipped upward to demold.

[0014] According to some embodiments of the present invention, the side core-pulling mechanism includes a core-pulling block for forming a transverse channel and a driving structure for driving the core-pulling block to pull the core transversely.

[0015] According to some embodiments of the present invention, the tops of the ejection structure and the rotating ejection mechanism are both in contact with the bottom of the forming core-pulling block.

[0016] This utility model has at least the following beneficial effects:

[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0027] An embodiment of this utility model provides a mold with a rotating ejection mechanism, such as... Figure 1-6 As shown, it includes: a front mold assembly 101, a rear mold assembly 102 disposed below the front mold assembly 101, an ejector assembly 103 disposed below the rear mold assembly 102, a base plate 104 disposed below the ejector assembly 103, a side core-pulling mechanism 2 disposed on the front mold assembly 101 for forming the transverse channel 401, and a rotating ejector mechanism 3 disposed on the rear mold assembly 102 and connected to the ejector assembly 103;

[0028] The rotating ejection mechanism 3 includes an ejection structure 301 for forming the vertical channel 402 and a rotating structure 302 provided on the ejection structure 301 for forming the guide slope 403; during demolding, the ejection assembly 103 can drive the rotating structure 302 to eject upwards and demold, and at the same time drive the rotating structure 302 to rotate and demold.

[0029] During demolding, the side core-pulling mechanism 2 first pulls the core laterally, facilitating demolding of the rotating ejector mechanism 3. The ejector assembly 103 drives the ejector structure 301 upwards, simultaneously achieving demolding of the rotating structure 302. This linked demolding method allows the rotating structure 302 to demold the guide ramp 403 while the vertical channel 402 is demolding, enabling molding and demolding within a small space and reducing demolding steps. Compared to structures like the inclined ejector structure, which require lateral displacement of the vertical channel 402 to achieve demolding of the guide ramp 403, the rotating structure 302 reduces lateral displacement requirements through rotation, eliminating defects caused by collisions and interference during demolding. The structure is mounted on the ejector structure 301, reducing the complexity and size of the mold. Specifically, the ejection method can involve directly lifting the rotating structure 302 using ejector pins, ejector plates, or ejector sleeves, or indirectly lifting the rotating structure 302 by lifting the ejection structure 301 or the molding part 4, so that the rotating structure 302 can complete the demolding of the guide slope 403 through rotation. When the mold is reset, the rotating structure 302 can be reset along with the reset of the ejection structure 301, or it can be pushed and reset along with the reset of the side core-pulling mechanism 2.

[0030] In some embodiments, such as Figure 3 , 5 As shown, the rotating structure 302 includes a fixed base 303 disposed on the top of the ejection structure 301 and a rotatable rotating block 304 disposed on the fixed base 303. The rotating block 304 includes a forming part 305 for forming the guide slope 403 and a rotating part 306 for rotating.

[0031] The rotatability of the rotating block 304 allows the guide slope 403 to detach from the formed guide slope during demolding by rotation. The rotating part 306 can be located at the middle or end of the rotating block 304. The rotating part 306 can be directly fixed to the fixed base 303 for rotation, or it can be fixed to the ejector structure 301 for rotation. Furthermore, as in this embodiment, the rotating part 306 can also be movably fixed to the ejector structure 301 and rotate under the limiting action of the fixed base 303, resulting in a flexible and versatile structure with wide applicability.

[0032] Furthermore, such as Figure 1-2As shown, the rotating part 306 includes a connecting block 307 and a rotating shaft 308 disposed at the end of the connecting block 307. The fixed base 303 is provided with a first groove 309 that cooperates with the connecting block 307. When the rotating block 304 rotates, the connecting block 307 can slide relative to it within the first groove 309.

[0033] The connecting block 307 serves to connect the rotating shaft 308 and the molding part 305. In this embodiment, the connecting block 307 extends downward to facilitate the rotating block 304 being engaged in the fixed seat 303, so that its top surface abuts against the bottom surface of the side core-pulling mechanism 2, ensuring the precise positioning of the rotating block 304 during molding and demolding. Meanwhile, the rotating shaft 308 provides a reliable rotation fulcrum for the rotating block 304, allowing it to rotate smoothly and steadily during demolding. Specifically, the rotating shaft 308 can rotate within the first groove 309, or it can rotate through the first groove 309 under the fixed seat 303, or it can rotate on the ejector structure 301.

[0034] Furthermore, such as Figure 3-5 As shown, the rotating shaft 308 is located below the first groove 309, and the length of the rotating shaft 308 is greater than the width of the first groove 309.

[0035] The length of the rotating shaft 308 is greater than the width of the first groove 309, which can confine the rotating block 304 within the fixed seat 303, preventing accidental detachment during rotation, and also providing a reliable support point for the rotating block 304. Specifically, the rotating shaft 308 can be fixed inside the bottom of the fixed seat 303, or it can pass through the fixed seat 303 and be fixed to the top of the ejector structure 301.

[0036] Furthermore, such as Figure 3-6 As shown, the top of the ejector structure 301 is provided with a second groove 311 that cooperates with the rotating shaft 308, and the rotating shaft 308 can rotate within the second groove 311.

[0037] The second groove 311, in conjunction with the rotating shaft 308, provides a limiting space for the rotating block 304, allowing it to be movably fixed, facilitating disassembly and subsequent maintenance, and improving the mold's service life. Furthermore, the top of the ejector structure 301 is provided with a third groove 310 for placing the fixed seat 303, enhancing the stability of the fixed seat 303 and increasing the overall molding height of the rotating structure 302. This prevents displacement during molding and demolding, thus ensuring the molding accuracy of the guide slope 403.

[0038] Furthermore, such as Figure 3 As shown, the rotating structure 302 includes a positioning structure 312 disposed on one side of the rotating part 306 for positioning the forming part 305.

[0039] The positioning structure 312 improves the forming accuracy of the rotating structure 302. It can be a limiting protrusion, sliding groove, buckle, or other structure that enables the forming part 305 to be quickly positioned.

[0040] Furthermore, such as Figure 4-6 As shown, the positioning structure 312 includes a positioning block 313 disposed on the top of the ejector structure 301, and the bottom of the rotating part 306 has a positioning groove 314 that cooperates with the positioning block 313. When the rotating block 304 is reset, the positioning block 313 can be inserted into the positioning groove 314.

[0041] The cooperation between the positioning block 313 and the positioning groove 314 ensures that the rotating block 304 can accurately return to its initial position during reset, avoiding molding errors or demolding interference caused by inaccurate reset.

[0042] In some embodiments, such as Figure 2-4 As shown, the ejection structure 301 includes a forming rod 315 and a push tube 316 sleeved on the outside of the forming rod 315; the bottom of the forming rod 315 is connected to the base plate 104; the bottom of the push tube 316 is connected to the ejection assembly 103; the rotating ejection mechanism 3 is located on the top of the forming rod 315; during demolding, the ejection assembly 103 can push the push tube 316 upward to drive the molded part 4 to be lifted upward, and the rotating structure 302 can be lifted by the molded part 4 and flipped upward to demold.

[0043] The push tube 316 is sleeved on the outside of the forming rod 315 and is used to form the bottom of the molded part 4. It also pushes the molded part 4 out of the mold during demolding. Because the bottom of the forming rod 315 is connected to the base plate 104, the ejector assembly 103 keeps the push tube 316 stationary when pushing it upwards, while the rotating structure 302 is lifted during the lifting process of the molded part 4, achieving flipping demolding and avoiding interference and damage. The abutment design between the forming rod 315 and the side core-pulling mechanism 2 ensures the accurate forming of the transverse channel 401, while the connection between the push tube 316 and the ejector assembly 103 provides stable power support for the entire demolding process.

[0044] Furthermore, such as Figure 2-3 As shown, the side core-pulling mechanism 2 includes a core-pulling block 201 for forming the transverse channel 401 and a drive structure 202 for driving the core-pulling block 201 to pull the core laterally; the tops of the ejection structure 301 and the rotating ejection mechanism 3 are both in contact with the bottom of the core-pulling block 201.

[0045] Since the core-pulling block 201 is a horizontal core-pulling block, which is inconsistent with the mold opening direction, it is pulled horizontally by the drive structure 202 such as a hydraulic cylinder. The bottom of the core-pulling block abuts against the forming rod 315, the ejector structure 301, and the rotating structure 302, forming a tight linkage structure. This allows the forming rod 315, the ejector structure 301, and the rotating structure 302 to be restricted in position during molding, ensuring the precise molding of the horizontal channel 401, the vertical channel 402, and the guide slope 403. Furthermore, it allows for direct pushing and resetting of the rotating structure 302 after rotation.

[0046] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
