Description

Technical Field

[0001] This invention relates to the field of injection molding technology, and more particularly to a male mold and an injection mold. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of styles and shapes (from simple to complex), sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] In existing technology, injection molds include a male mold and a female mold, which separate after injection molding. The product is usually located on the male mold, which has an ejector pin structure to eject the product. In injection molding, the molded object includes not only the desired product but also the sprue. Before ejecting the product, the sprue needs to be ejected first, followed by the product. This ejection sequence ensures the desired product appearance and feature integrity. However, existing injection molds have poor stability during ejection. Specifically, the male mold's float plate may slightly spring back during mold opening. Since the product is located on the float plate, its movement can cause product deformation, damage, and other issues, leading to quality problems, failing to achieve the desired product appearance, and making it difficult to guarantee the integrity of product features.

[0004] Therefore, there is an urgent need for a public mold and injection mold to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a common mold that can reduce the probability of product deformation and damage during ejection, and has high reliability.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0012] The abutment assembly includes an abutment structure and an elastic abutment member sleeved on the abutment structure. One end of the abutment structure is connected to the product ejector pin assembly, and the other end passes through the male mold base plate and the male mold float plate in sequence and is limited to the side of the male mold float plate away from the male mold base plate. The elastic abutment member abuts against the male mold base plate and the product ejector pin assembly so that the male mold base plate is tightly attached to the male mold float plate.

[0013] Optionally, the abutment structure includes an abutment body and a spacer connected to one end of the abutment body. The other end of the abutment body is connected to the product ejector pin assembly. The surface of the spacer connected to the abutment body can contact the surface of the male mold floating plate away from the male mold base plate.

[0014] Optionally, it also includes a first limiting member, wherein the male mold base plate is provided with a receiving structure, a first limiting head at one end of the first limiting member is slidably disposed in the receiving structure and can be limited by the receiving structure, and the other end of the first limiting member is connected to the male mold floating plate.

[0015] Optionally, it further includes a guide rod and an elastic reset member sleeved on the guide rod. One end of the guide rod is connected to the male mold base plate, and the other end of the guide rod passes through the sprue ejector plate and is installed in the product ejector assembly. One end of the elastic reset member abuts against the sprue ejector plate, and the other end of the elastic reset member abuts against the male mold base plate.

[0016] Optionally, it also includes a second limiting member. The surface of the product ejector assembly away from the sprue ejector plate is provided with a limiting groove. A second limiting head at one end of the second limiting member is located in the limiting groove. The other end of the second limiting member is connected to the mold base plate. The product ejector assembly and the sprue ejector plate can slide on the second limiting member. The second limiting member is used to limit the reset distance of the product ejector assembly and the sprue ejector plate.

[0017] Optionally, it also includes a third limiting member, which is disposed on the surface of the sprue ejector plate facing the male mold base plate and is used to limit the lower limit of the distance between the sprue ejector plate and the male mold base plate.

[0018] Optionally, it also includes a pusher, one end of which is connected to the sprue ejector plate, and the other end of which passes through the product ejector assembly and is exposed for a predetermined length of the product ejector assembly.

[0019] Optionally, multiple abutment components are provided, which are evenly and spaced apart, and the sprue ejector plate is provided with multiple clearance openings corresponding to the multiple abutment components, through which the abutment components pass.

[0020] Optionally, the product ejector assembly includes a product ejector plate and an ejector base plate. The ejector base plate is located on the side of the product ejector plate away from the sprue ejector plate. At least one product ejector pin is mounted on the product ejector plate. The elastic abutment abuts against the mold base plate and the product ejector plate. One end of the abutment structure is connected between the product ejector plate and the ejector base plate.

[0021] The purpose of this invention is to provide an injection mold with high reliability.

[0023] The injection mold includes a female mold and a male mold as described above. The female mold can be engaged with the male mold, and the surface of the female mold facing the male mold float is provided with a relief groove to avoid the abutment structure.

[0024] The beneficial effects of this invention are:

[0025] The male mold and injection mold provided by this invention, by setting a resisting structure and an elastic resisting component, wherein one end of the resisting structure is connected to the product ejector pin assembly, and the other end of the resisting structure is limited to the side of the male mold float away from the male mold base plate, and the elastic resisting component elastically resists the male mold base plate against the male mold float plate, so that the male mold base plate and the male mold float plate can be tightly attached. During the mold opening process, when the female mold and the male mold float plate are separated, the elastic resisting component tightly attaches the male mold base plate to the male mold float plate, thereby preventing the male mold float plate from springing away from the male mold base plate, ensuring the order of ejection head and product, and preventing problems such as deformation and damage caused by the movement of the male mold float plate at the moment of mold opening, so as to achieve a rational product appearance, ensure the integrity of product features and product quality, and have high reliability.

[0038] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0043] This embodiment provides a common mold that can reduce the probability of product deformation or damage during ejection, and has high reliability.

[0044] like Figure 1 and Figure 2 As shown, the mold includes a mold base plate 1, a mold float plate 2, a sprue ejector plate 3, a product ejector assembly 4, and an ejector assembly 5.

[0045] The male mold float 2 is located on one side of the male mold base plate 1. The male mold float 2 can be used to connect with the female mold 100; the connection method can refer to existing technology. A limited relative displacement can occur between the male mold float 2 and the male mold base plate 1, which will be described in detail later. The sprue ejector plate 3 is located on the other side of the male mold base plate 1; that is, the sprue ejector plate 3 and the male mold float 2 are located on opposite sides of the male mold base plate 1, as shown below. Figure 8As shown, at least one sprue ejector pin 30 is mounted on the sprue ejector plate 3. The sprue ejector pin 30 passes through the male mold base plate 1 and the male mold float plate 2 and is used to eject the sprue head formed simultaneously with the product during injection molding. The product ejector assembly 4 is located on the side of the sprue ejector plate 3 away from the male mold base plate 1. At least one product ejector pin 40 is mounted on the product ejector assembly 4, and the product ejector pin 40 is used to eject the product. In this embodiment, the connection method between the male mold base plate 1 and the sprue ejector plate 3, and between the sprue ejector plate 3 and the product ejector assembly 4, can refer to the prior art. This embodiment does not limit this, as long as the corresponding function can be achieved.

[0046] like Figure 3 As shown, the abutment assembly 5 includes an abutment structure 51 and an elastic abutment member 52 sleeved on the abutment structure 51. One end of the abutment structure 51 is connected to the product ejector pin assembly 4, and the other end passes sequentially through the male mold base plate 1 and the male mold float plate 2, and is confined to the side of the male mold float plate 2 away from the male mold base plate 1. The elastic abutment member 52 abuts against the male mold base plate 1 and the product ejector pin assembly 4, thereby abutting the male mold base plate 1 against the male mold float plate 2, so that when the male mold and female mold 100 separate, the male mold float plate 2 will not move relative to the male mold base plate 1. It should be noted that the elastic abutment member 52 can be a spring or similar component, and the elastic abutment member 52 is in a contracted state, providing a force through the elastic abutment member 52 to press against the male mold float plate 2.

[0047] The male mold provided in this embodiment is equipped with a resisting structure 51 and an elastic resisting member 52. One end of the resisting structure 51 is connected to the product ejector pin assembly 4, and the other end of the resisting structure 51 is limited to the side of the male mold float plate 2 away from the male mold base plate 1. The elastic resisting member 52 elastically resists the male mold base plate 1 against the male mold float plate 2, so that the male mold base plate 1 and the male mold float plate 2 can be tightly attached. During the mold opening process, when the female mold 100 separates from the male mold float plate 2, the elastic resisting member 52 tightly attaches the male mold base plate 1 to the male mold float plate 2, so that the male mold float plate 2 will not spring away from the male mold base plate 1. This ensures the order of ejection head and product, and prevents problems such as deformation and damage caused by the movement of the male mold float plate 2 at the moment of mold opening. This achieves a rational product appearance, ensures the integrity of product features and product quality, and has high reliability.

[0048] Optionally, please continue to see Figure 3The abutment structure 51 includes an abutment body 511 and a spacer 512 connected to one end of the abutment body 511. The other end of the abutment structure 51 is limited by the spacer 512 to the side of the male mold float plate 2 away from the male mold base plate 1. Specifically, the other end of the abutment body 511 is connected to the product ejector assembly 4, and the surface of the spacer 512 connected to the abutment body 511 can contact the surface of the male mold float plate 2 away from the male mold base plate 1. That is, the cross-section of the hole in the male mold float plate 2 through which the abutment body 511 passes is smaller than the cross-section of the spacer 512, so that the spacer 512 will not move into the hole, thereby limiting one end of the abutment body 511. In some embodiments, the abutment body 511 is cylindrical, such as cylindrical in shape, and the spacer 512 is cylindrical in shape, so that it can have a larger contact area with the male mold float plate 2, thereby ensuring the reliability of limiting one end of the abutment body 511.

[0049] Optionally, please continue to see Figure 3 The other end of the abutment body 511 has a protruding structure arranged radially along the abutment body 511 to improve the reliability of the abutment body 511 in the product ejector assembly 4 and prevent the abutment body 511 from coming out of the product ejector assembly 4.

[0050] It should be noted that during product ejection, the male mold float 2 can move relative to the male mold base plate 1 to better eject the product. In some optional embodiments, such as Figure 2 and Figure 4 As shown, the male mold also includes a first limiting member 6, which limits the distance the male mold float 2 moves relative to the male mold base plate 1. The male mold base plate 1 is provided with a receiving structure. One end of the first limiting member 6 has a first limiting head 61 with a large cross-sectional area. The first limiting head 61 is slidably disposed in the receiving structure and can be limited by the receiving structure. That is, the first limiting head 61 can slide in the receiving structure, and in the direction from the male mold base plate 1 to the male mold float 2, the receiving structure can limit the movement limit of the first limiting head 61. The other end of the first limiting member 6 is connected to the male mold float 2, thereby realizing the movement limit of the male mold float 2. For example, the receiving structure can be a groove structure or a sliding hole structure. This embodiment does not limit this. In this embodiment, the receiving structure is a groove structure provided on the surface of the male mold base plate 1 away from the male mold float 2. The first limiting member 6 can be a bolt, and the first limiting head 61 is specifically a bolt nut.

[0051] Optionally, such as Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the male mold also includes a guide rod 7 and an elastic reset member 8 sleeved on the guide rod 7. One end of the guide rod 7 is connected to the male mold base plate 1, and the other end passes sequentially through the sprue ejector plate 3 and the product ejector assembly 4. The sprue ejector plate 3 and the product ejector assembly 4 can slide on the guide rod 7 and be guided by it. One end of the elastic reset member 8 abuts against the sprue ejector plate 3, and the other end abuts against the male mold base plate 1. The elastic reset member 8 is used for resetting the sprue ejector plate 3. In other embodiments, the elastic reset member 8 can also assist the elastic abutment member 52 in resetting the product ejector assembly 4.

[0052] Further optional, such as Figure 2 and Figure 5 As shown, the male mold also includes a second limiting member 9, which is used to limit the reset distance of the product ejector assembly 4 and the sprue ejector plate 3. Specifically, the surface of the product ejector assembly 4 away from the sprue ejector plate 3 is provided with a limiting groove 41. One end of the second limiting member 9 has a second limiting head 91 with a cross-sectional area larger than that of the main body of the second limiting member 9. The second limiting head 91 is located in the limiting groove 41 and can be limited by the limiting groove 41. The other end of the second limiting member 9 is connected to the male mold base plate 1. The product ejector assembly 4 and the sprue ejector plate 3 can slide on the second limiting member 9, so that the second limiting member 9 can limit the reset distance of the product ejector assembly 4 and the sprue ejector plate 3, so as to ensure that when in the reset state, the distance between the sprue ejector plate 3 and the male mold base plate 1 and the distance between the product ejector assembly 4 and the male mold base plate 1 are preset distances. In this embodiment, the second limiting head 91 is cylindrical, and the limiting groove 41 is a cylindrical groove that cooperates with the cylindrical second limiting head 91.

[0053] In some alternative embodiments, such as Figure 5 , Figure 7 Figure 9 and Figure 10 As shown, the male mold also includes a third limiting member 10. The third limiting member 10 is disposed on the surface of the sprue ejector plate 3 facing the male mold base plate 1 and is connected to the sprue ejector plate 3. It is used to limit the lower limit of the distance between the sprue ejector plate 3 and the male mold base plate 1, that is, to limit the minimum value of the distance between the sprue ejector plate 3 and the male mold base plate 1. Specifically, the minimum value of the distance between the sprue ejector plate 3 and the male mold base plate 1 is equal to the length of the portion of the third limiting member 10 exposed on the sprue ejector plate 3 in the thickness direction of the sprue ejector plate 3. By setting the third limiting member 10, the moving distance of the sprue ejector plate 3 when moving towards the male mold base plate 1 can be limited, so as to ensure the size of the ejected sprue head and facilitate subsequent processing and manufacturing.

[0054] In this embodiment, after the male mold and female mold 100 separate, the ejector head and product need to be ejected by a cylinder or linear motor. In this embodiment, during the ejection process, the cylinder or linear motor can apply force to the pusher 20 to drive the sprue ejector plate 3. Figures 8 to 10 As shown, one end of the pusher 20 is connected to the sprue ejector plate 3, and the other end of the pusher 20 passes through the product ejector assembly 4 and protrudes from the surface of the product ejector assembly 4 away from the sprue ejector plate 3 by a predetermined length. The pusher 20 moves under the action of an external force, pushing the sprue ejector plate 3 closer to the male mold base plate 1, thereby moving the sprue ejector pin 30 to eject the sprue head. In this embodiment, the predetermined length is equal to the ejection length of the sprue head.

[0055] It should be noted that after the material head is ejected, the end face of the pusher 20 away from the sprue ejector plate 3 is flush with the surface of the product ejector assembly 4 away from the sprue ejector plate 3. At this point, to eject the product, the product ejector assembly 4 needs to be directly pushed by a cylinder or linear motor to move the product ejector 40 and eject the product. It should also be noted that when pushing the product ejector assembly 4, it needs to avoid the second limiting member 9 so that the product ejector assembly 4 can slide on the second limiting member 9. In some embodiments, the pusher 20 has a cylindrical structure.

[0056] In some alternative embodiments, such as Figures 1 to 8 As shown, multiple abutment components 5 are provided, and these components 5 are evenly and spaced apart to ensure that the male mold base plate 1 and the male mold float plate 2 can fit together evenly, preventing the male mold float plate 2 from partially lifting. Furthermore, as... Figure 7 As shown, the sprue ejector plate 3 is provided with multiple clearance openings 31 corresponding to multiple abutment components 5. Each abutment component 5 passes through its corresponding clearance opening 31. That is, the abutment structure 51 and the elastic abutment member 52 pass through the corresponding clearance opening 31, so that there is no need to open holes in the sprue ejector plate 3, and the sprue ejector plate 3 does not need to be large, saving materials and costs.

[0057] Optional, please see Figure 6The product ejector assembly 4 includes a product ejector plate 42 and an ejector base plate 43. The ejector base plate 43 is located on the side of the product ejector plate 42 away from the sprue ejector plate 3. That is, the ejector base plate 43, product ejector plate 42, sprue ejector plate 3, mold base plate 1, and mold float plate 2 are arranged sequentially. At least one product ejector pin 40 is mounted on the product ejector plate 42. In some embodiments, the ejector base plate 43 and the product ejector plate 42 are interconnected, and the product ejector pin 40 is sandwiched between the ejector base plate 43 and the product ejector plate 42. An elastic abutment member 52 abuts against the mold base plate 1 and the product ejector plate 42. One end of the abutment structure 51 is connected between the product ejector plate 42 and the ejector base plate 43. Specifically, the surface of the product ejector plate 42 facing the ejector base plate 43 has an abutment groove, the ejector base plate 43 covers the abutment groove, and a protruding structure at one end of the abutment structure 51 is limited within the abutment groove.

[0058] The mold provided in this embodiment has a sprue ejection process and a product ejection process during ejection, with the sprue ejection process occurring before the product ejection process. The specific ejection process is as follows:

[0059] Figure 1 This is a schematic diagram showing the male mold and female mold 100 in a snap-fit ​​state. After mold opening, the state of the male mold is the same as... Figure 1 The state of the male mold is the same as shown. At this time, the sprue ejector plate 3 is attached to the product ejector plate 42 under the action of the elastic reset member 8. There is no gap between the male mold base plate 1 and the male mold float plate 2, and the push member 20 is exposed beyond the preset length of the ejector base plate 43. During the ejection process of the sprue head, an external force is applied to the push member 20, and the direction of the force is... Figure 1 From left to right, the pusher 20 moves to the right, pushing the sprue ejector plate 3 to the right. Simultaneously, the sprue ejector plate 3 drives the third limiting member 10 to the right, and the sprue ejector 30 also moves to the right. When the left end face of the pusher 20 is flush with the surface of the ejector base plate 43 away from the product ejector plate 42, the sprue head is ejected, thus completing the sprue head ejection step. At this point, the mold presents the following appearance: Figure 9 In this state, the product ejector pin assembly 4 remains stationary, while the elastic reset member 8 is further compressed. (As described) Figure 9 As shown, there is a gap between the sprue ejector plate 3 and the product ejector plate 42. Next, a force is applied to the ejector base plate 43, which pushes the ejector base plate 43, the product ejector plate 42, and the sprue ejector plate 3 together closer to the male mold base plate 1. The ejector base plate 43, the product ejector plate 42, and the sprue ejector plate 3 slide on the guide rod 7 and the second limiting member 9, and the elastic reset member 8 is further compressed, and the elastic abutment member 52 is further compressed. When the third limiting member 10 contacts the male mold base plate 1, the product is completely ejected, completing the product ejection process. At this time, the male mold presents the following position: Figure 10The state shown. After the product is removed, the external force applied to the ejector base plate 43 disappears, and under the action of the elastic reset member 8 and the elastic abutment member 52, the sprue ejector plate 3, the product ejector plate 42, the ejector base plate 43, the abutment structure 51, the first limiting member 6, and the third limiting member 10 all reset. Figure 10 As shown, the male mold float 2 moves a short distance to the right and is then stopped by the first limiting member 6. It should be noted that the short rightward movement of the male mold float 2 is achieved by a pusher. One end of the pusher is connected to the product ejector plate 42 and / or ejector base plate 43, or one end of the pusher is positioned between the product ejector plate 42 and ejector base plate 43, while the other end of the pusher contacts the male mold float 2. Specifically, the male mold float 2 has a spring groove containing a spring piece. The other end of the pusher contacts the spring piece. During the movement of the product ejector plate 42 and ejector base plate 43, the spring piece does not undergo elastic deformation in the initial stage. At this time, the pusher pushes the spring piece and the male mold float 2 to the right. After moving a short distance, the male mold float 2 is stopped by the first limiting member 6 and cannot continue moving. The pusher continues to move to the right, compressing the spring piece and causing it to undergo elastic deformation. After the product is removed, when the external force applied to the ejector base plate 43 disappears, the spring piece returns to its original shape.

[0060] In this embodiment, the male mold float 2 effectively synchronizes with the ejector pins' ejection and reset sequence after the product is injection molded and the mold opens. During mold opening, the float 2 is fixed by the limiting element 512, and under the strong reset action of the elastic abutment 52, the float 2 and the base plate 1 of the male mold are effectively glued together, ensuring the product remains in the male mold at the moment of mold opening without deformation or damage. Furthermore, the element 512 in this embodiment is made of SKD61 high-strength steel with a hardness of 52°. The abutment body 511, through the tension of the elastic abutment 52, achieves the fixing effect of the float 2, ensuring the orderly ejection action during mold opening.

[0061] This embodiment also provides an injection mold, such as Figure 1 As shown, the injection mold includes a female mold 100 and the aforementioned male mold. The female mold 100 can engage with the male mold, and, as... Figure 3 As shown, the female mold 100 has a relief groove 101 with a relief and abutment structure 51 on the surface facing the male mold floating plate 2. The spacer 512 is placed in the relief groove 101 so that the setting of the spacer 512 will not increase the thickness of the injection mold.

[0062] The injection mold provided in this embodiment has a male mold with a stop structure 51 and an elastic stop member 52. One end of the stop structure 51 is connected to the product ejector pin assembly 4, and the other end of the stop structure 51 is limited to the side of the male mold float plate 2 away from the male mold base plate 1. The elastic stop member 52 elastically abuts the male mold base plate 1 against the male mold float plate 2, so that the male mold base plate 1 and the male mold float plate 2 can be tightly attached. During the mold opening process, when the female mold 100 separates from the male mold float plate 2, the elastic stop member 52 tightly attaches the male mold base plate 1 to the male mold float plate 2, so that the male mold float plate 2 will not spring away from the male mold base plate 1. This ensures the order of ejection head and product, and prevents problems such as deformation and damage caused by the movement of the male mold float plate 2 at the moment of mold opening. This achieves a rational product appearance, ensures the integrity of product features and product quality, and has high reliability.
