Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding equipment, and in particular relates to a mold ejection structure and an injection mold. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding and processing fields such as products with complex shapes. In the production process of injection molded products, molten plastic is injected into the injection mold under high pressure. The plastic enters the cavity from the runner of the injection mold through the gate, and forms an injection molded product after cooling and solidification in the cavity. The injection molded product is removed from the injection mold through processes such as mold opening and ejection.

[0003] An ejector mechanism is generally provided on the injection mold. The ejector mechanism is usually used in conjunction with a cylinder. The cylinder is provided at the bottom of the mold. The cylinder drives the ejector mechanism to eject the obtained injection molded product upward when the injection molding is completed and the mold is opened, so that the injection molded product can be easily obtained by an external robot or manually. However, in the existing injection mold, the force direction of the cylinder is the same as the ejection direction of the injection molded product, and the space for placing the cylinder at the bottom of the mold is limited, resulting in insufficient ejection stroke of the cylinder. Therefore, the movement stroke of the ejector mechanism is limited, so that the injection molded product cannot be completely separated from the cavity. Utility Model Content

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0034] See also Figures 1 to 4 The embodiment of the present application provides a mold ejection structure for ejecting the molding in the mold cavity. It can be understood that the mold ejection structure is usually used in injection molding equipment, which is used to inject molten plastic material into the mold cavity with high pressure, and obtain a molded product after cooling and solidification.

[0035] Injection molding generally includes a mold frame, an injection molding mechanism, a fixed mold 200 and a movable mold 300, etc. The fixed mold 200 and the movable mold 300 can close and open the mold, the fixed mold 200 has a first cavity, and the movable mold 300 has a second cavity. The first cavity and the second cavity cooperate to form a cavity for molding an injection molded part 100. The injection molding mechanism is used to inject molten plastic material into the cavity. The shape and size of the cavity match the shape and size of the injection molded part 100 to be molded, so that the injection molding mechanism can cool and solidify the molten plastic material into the cavity after injecting it into the cavity. When the fixed mold 200 and the movable mold 300 open the mold, the molded part 100 that has been molded in the cavity can be ejected by the mold ejection structure to be separated from the cavity.

[0036] In the present application, the mold ejection structure includes a power structure 10, a transmission structure 20 and an ejector assembly 30. The transmission structure 20 is connected to the output end of the power structure 10. The power structure 10 is used to transmit power to the transmission mechanism along a first direction X. One end of the ejector assembly 30 abuts against the molded part 100, and the other end of the ejector assembly 30 is transmission-connected to the transmission structure 20 so as to be driven by the transmission structure 20 and eject the molded part 100 along a second direction Y. The first direction X and the second direction Y are arranged at an angle.

[0037] The mold ejection structure provided in the present application is provided with a transmission structure 20. The transmission structure 20 can realize the conversion of the power of the power structure 10 along the first direction X into the thrust of the ejector assembly 30 along the second direction Y, and the first direction X and the second direction Y form an angle with each other. The driving stroke of the power structure 10 does not occupy the ejection stroke of the molded part 100, so that the driving stroke of the power structure 10 is not restricted, and therefore the moving stroke of the ejection mechanism is not restricted, so that the molded part 100 can be completely separated from the mold cavity, thereby improving the smoothness of demolding; moreover, since the mold does not need to reserve space for the driving stroke of the power structure 10 in the ejection direction of the molded part 100, the size of the mold along the ejection direction of the molded part 100 can be reduced, making the mold structure more compact.

[0038] Preferably, if Figure 2 and Figure 3 As shown, the transmission structure 20 is a toggle mechanism, and the power structure 10 is used to drive the toggle mechanism to straighten or bend, so that the ejector assembly 30 ejects the molded part 100 or retracts along the second direction Y. It can be understood that the toggle mechanism is straightened, that is, the toggle mechanism is straightened along the second direction Y. When the toggle mechanism changes from a bent state to an extended state, the length of the toggle mechanism along the second direction Y increases, which can drive the ejector assembly 30 to extend along the second direction Y, thereby ejecting the molded part 100; and when the toggle mechanism changes from a straight state to a bent state, the length of the toggle mechanism along the second direction Y decreases, thereby driving the ejector assembly 30 to retract. By setting up the toggle mechanism, the present application has a simple structure, does not interfere with other structures of the injection mold, is convenient for manufacturing and maintenance, and has strong stability.

[0039] In some embodiments, the mold ejection structure also includes a base plate 40, and a toggle mechanism is arranged between the ejector assembly 30 and the base plate 40. The base plate 40 can be placed on a workbench, so the base plate 40 is fixed. The toggle mechanism includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 and the second connecting rod 22 are hinged through a first hinge structure 25. The end of the first connecting rod 21 away from the first hinge structure 25 is hinged to the ejector assembly 30, and the end of the second connecting rod 22 away from the first hinge structure 25 is hinged to the base plate 40. The power structure 10 is used to drive the first hinge structure 25 to move along the first direction X so that the angle formed by the first connecting rod 21 and the second connecting rod 22 increases or decreases.

[0040] It can be understood that the line a between the hinge point of the first link 21 and the ejector assembly 30 and the hinge point of the second link 22 and the bottom plate 40 is in the same direction or nearly in the same direction as the second direction Y, and the first hinge structure 25 is located on one side of the line a. When the power structure 10 drives the first hinge structure 25 to move along the first direction X and approach the line a, the angle formed by the first link 21 and the second link 22 gradually increases, which is equivalent to the first link 21 and the second link 22 "expanding" to both sides. At this time, the bottom plate 40 is fixed, and the end of the first link 21 moves away from the first hinge structure 25 along the second direction Y. The first connecting rod 21 moves in the direction of the first hinge structure 25, thereby driving the ejector assembly 30 to move away from the bottom plate 40, so that the molded part 100 is ejected away from the bottom plate 40; and when the power structure 10 drives the first hinge structure 25 to move along the first direction X and away from the connecting line a, the angle formed by the first connecting rod 21 and the second connecting rod 22 gradually decreases, which is equivalent to the first connecting rod 21 and the second connecting rod 22 "closing", and the end of the first connecting rod 21 moves along the second direction Y toward the first hinge structure 25, thereby driving the ejector assembly 30 to move toward the bottom plate 40, so that the ejector assembly 30 retracts in the direction toward the bottom plate 40. It can be understood that if the angle formed by the first connecting rod 21 and the second connecting rod 22 is 180 degrees, the ejector assembly 30 has the farthest ejection stroke at this time.

[0041] Optionally, the toggle mechanism of the present application may include a plurality of connecting rods arranged along the second direction Y, the plurality of connecting rods are hinged in sequence, and two adjacent connecting rods are connected by a hinge structure. Therefore, the toggle mechanism of the present application may include a plurality of hinge structures. Accordingly, a plurality of power structures 10 may also be provided, and each power structure 10 is connected to each hinge structure. Each power structure 10 drives each hinge structure to connect and move, and then transmits a plurality of connecting rods, thereby improving the transmission efficiency of the transmission structure 20.

[0042] In other possible embodiments, the mold ejection structure may further include a guide structure. When the multiple power structures 10 drive the multiple hinged structures to move, the multiple connecting rods are driven to connect the ejector pin assembly 30 under the limit of the guide structure, thereby reasonably limiting the force transmission direction and making the transmission of the transmission structure 20 more stable.

[0043] Furthermore, the toggle mechanism also includes a third connecting rod 23 and a fourth connecting rod 24, and the third connecting rod 23 and the fourth connecting rod 24 are hinged through a second hinge structure 26. The end of the third connecting rod 23 away from the second hinge structure 26 is hinged to the ejector assembly 30, and the end of the fourth connecting rod 24 away from the second hinge structure 26 is hinged to the base plate 40. The power structure 10 includes a cylinder body 11 and a push rod 12 that can be telescopically connected to the cylinder body 11 along a first direction X. The second hinge structure 26 is connected to the cylinder body 11, and the first hinge structure 25 is connected to the end of the push rod 12 away from the cylinder body 11.

[0044] When the push rod 12 is extended, the distance between the first hinge structure 25 and the second hinge structure 26 increases, the angle formed by the first link 21 and the second link 22 and the angle formed by the third link 23 and the fourth link 24 decrease, and the ejector assembly 30 moves toward the bottom plate 40, so that the ejector assembly 30 retracts in the direction close to the bottom plate 40; when the push rod 12 is retracted, the distance between the first hinge structure 25 and the second hinge structure 26 decreases, the angle formed by the first link 21 and the second link 22 and the angle formed by the third link 23 and the fourth link 24 increase, and the ejector assembly 30 moves away from the bottom plate 40, so that the ejector assembly 30 ejects the molded part 100 in the direction away from the bottom plate 40. By providing the third link 23 and the fourth link 24, and providing the first hinge structure 25 and the second hinge structure 26 as two hinge structures, the transmission structure 20 can transmit the driving force of the power structure 10 more efficiently and fully, and the movement of the ejector assembly 30 can be more stable.

[0045] In addition, in the present application, the first connecting rod 21 and the third connecting rod 23 can also be hinged to the same rotating shaft, that is, the first connecting rod 21 and the third connecting rod 23 can be hinged to the same hinge seat, so that the structure of the toggle mechanism is simpler and cost can be saved.

[0046] Optionally, there are two groups of toggle mechanisms, which are arranged at intervals, and the two hinge points of the two groups of toggle mechanisms and the ejector assembly 30 are distributed on both sides of the ejector assembly 30, so that the ejector assembly 30 is more evenly stressed and moves more smoothly, and the two first hinge structures 25 of the two groups of toggle mechanisms are connected by a connecting plate 28, and the connecting plate 28 is connected to the end of the push rod 12 away from the cylinder body 11, so that the two first hinge mechanisms can be driven to move simultaneously through one connecting plate 28. In the present application, the push rod 12 is connected to the center of the connecting plate 28.

[0047] In some embodiments, the toggle mechanism also includes a third hinge structure 27, which is disposed on the base plate 40, and the end of the second connecting rod 22 away from the first hinge structure 25 and the end of the fourth connecting rod 24 away from the second hinge structure 26 are both hinged to the third hinge structure 27, and the two third hinge structures 27 of the two sets of toggle mechanisms are connected to the same rotating shaft. Therefore, the components of the transmission structure 20 of the present application are closely connected and have strong linkage, which can effectively improve the transmission stability of the transmission structure 20.

[0048] In the present application, the first direction X is perpendicular to the second direction Y, and the second direction Y is arranged in the same direction as the mold opening direction of the mold, that is, the second direction Y is perpendicular to the top surface of the bottom plate 40, so the present application can effectively utilize the horizontal space above the bottom plate 40 and increase the moving stroke of the ejector assembly 30. Of course, in other possible implementations, the first direction X and the second direction Y can also form other angles, such as 60°, 70°, 75°, etc., and the present application does not make a unique limitation on the angle formed between the first direction X and the second direction Y.

[0049] In some embodiments, the ejector pin assembly 30 includes a ejector plate 31 and a plurality of ejector pins 32 connected to the ejector plate 31, each ejector pin 32 abuts against the molded part 100, the ejector plate 31 is transmission-connected to the transmission structure 20, the transmission structure 20 transmits power to the ejector plate 31, and the ejector pin 32 moves with the ejector plate 31, so that the ejector pin 32 can eject the molded part 100 or retract along the second direction Y.

[0050] Specifically, the first link 21 and the third link 23 are hinged to the top plate 31, and the hinge points of the first link 21 and the third link 23 and the top plate 31 are located at the center of the top plate 31, so that the movement of the top plate 31 is smoother and does not deviate or shake to the sides, and a plurality of ejector pins 32 are arranged around the edge of the top plate 31, and each ejector pin 32 abuts against the edge of the molded part 100, so that the ejection process of the molded part 100 is smoother.

[0051] The utility model also proposes an injection mold, which includes a mold ejection structure. The specific structure of the mold ejection structure refers to the above-mentioned embodiment. Since the injection mold adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0052] In some embodiments, the injection mold includes a fixed mold 200 and a movable mold 300, the fixed mold 200 has a first cavity, the movable mold 300 has a second cavity, the first cavity and the second cavity cooperate to form a mold cavity for molding the injection-molded part 100, the ejector assembly 30 is connected to the fixed mold 200, and the power structure 10 and the transmission structure 20 are arranged on the side of the movable mold 300 away from the fixed mold 200.

[0053] In summary, the mold ejection structure provided by the present application, by setting the transmission structure 20, the transmission structure 20 can realize the conversion of the power of the power structure 10 along the first direction X into the thrust of the ejector assembly 30 along the second direction Y, and the first direction X and the second direction Y form an angle with each other, and the driving action stroke of the power structure 10 does not occupy the ejection space of the molded part 100, so that the driving action stroke of the power structure 10 is not restricted, and therefore the moving stroke of the ejection mechanism is not restricted, so that the molded part 100 can be completely separated from the mold cavity, thereby improving the smoothness of demolding; moreover, since the mold does not need to reserve space for the driving action stroke of the power structure 10 in the ejection direction of the molded part 100, the size of the mold along the ejection direction of the molded part 100 can be reduced, making the mold structure more compact.
