Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a double-layer inclined lift mechanism. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The heated and melted material is injected into the mold and the molded product is obtained after cooling and solidification.

[0003] In the process of demolding, undercut demolding is an issue that cannot be ignored. Therefore, how to achieve demolding with undercuts at different angles is a technical problem that needs to be solved urgently in mold technology. Summary of the invention

[0004] The present application provides a double-layer inclined ejector mechanism, which can realize demoulding with undercuts at different angles.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In the first aspect, an embodiment of the present application provides a double-layer inclined ejector mechanism, including a base plate, an ejector plate, a first inclined ejector rod, a second inclined ejector rod, a first inclined ejector block, and a second inclined ejector block; the ejector plate approaches or moves away from the base plate along a first direction, and the first direction is parallel to the vertical direction; along the length direction of the first inclined ejector rod, the first inclined ejector rod has a first end and a second end, the first end is located below the second end, and the first end is slidably disposed on the ejector plate; along the length direction of the second inclined ejector rod, the second inclined ejector rod has a third end and a fourth end, the third end is located below the fourth end, and the third end is slidably disposed on the ejector plate; the first inclined ejector block is disposed at the second end, and the second inclined ejector block is disposed at the fourth end, and the inclination angle of the first inclined ejector rod relative to the first direction is different from the inclination angle of the second inclined ejector rod relative to the first direction.

[0007] A double-layer inclined lift mechanism is proposed in an embodiment of the present application, and the first inclined lift rod and the second inclined lift rod are respectively provided with inclined lift blocks at one side end along their respective lengths, that is, the first inclined lift block and the second inclined lift block move synchronously with the corresponding first inclined lift rod and the second inclined lift rod respectively, and because the inclination angle of the first inclined lift rod compared to the first direction is different from the inclination angle of the second inclined lift rod compared to the first direction, when the first inclined lift rod and the second inclined lift rod slide, they slide along different angles respectively, thereby making the first inclined lift block and the second inclined lift block slide along different angles, thereby completing the demolding of two undercuts in different directions.

[0008] Optionally, the double-layer inclined ejector mechanism also includes a first slide and a second slide, the first slide is fixed to the ejector plate, the first slide is provided with a first slide groove, the first end has a first slider, and the first slider is slidably matched with the first slide groove; the second slide is fixed to the ejector plate, the second slide is provided with a second slide groove, the third end has a second slider, and the second slider is slidably matched with the second slide groove.

[0009] In the above scheme, the first slider located at the first end slides in the first sliding groove, that is, the first slider drives the first inclined lift rod to slide through the first end, so that the first inclined lift block exits the undercut; the second slider located at the second end slides in the second sliding groove, that is, the second slider drives the second inclined lift rod to slide through the second end, so that the second inclined lift block exits the undercut. The design of the slider and the sliding groove makes the movement process smoother, which helps to reduce errors and wear caused by shaking or vibration.

[0010] Optionally, the length direction of the first sliding groove is perpendicular to the length direction of the first inclined lift rod, and the length direction of the second sliding groove is perpendicular to the length direction of the second inclined lift rod.

[0011] In the above scheme, the length direction of the first slide groove is perpendicular to the length direction of the first inclined lift rod, so that the first inclined lift rod can move along the direction perpendicular to its own length direction, thereby realizing oblique movement, thereby realizing exiting the undercut along its inclination angle; the length direction of the second slide groove is perpendicular to the length direction of the second inclined lift rod, so that the second inclined lift rod can move along the direction perpendicular to its own length direction, thereby realizing oblique movement, thereby realizing exiting the undercut along its inclination angle direction.

[0012] Optionally, the angle between the first inclined lift rod and the first direction is greater than the angle between the second inclined lift rod and the first direction.

[0013] In the above scheme, since the angle between the first inclined lift rod and the first direction is greater than the angle between the second inclined lift rod and the first direction, that is, the downward slope angle of the first inclined lift rod is greater than the downward slope angle of the second inclined lift rod, the first inclined lift block can be separated from the product faster than the second inclined lift block, which helps to reduce the probability of interference between the first inclined lift block and the second inclined lift block.

[0014] Optionally, the angle between the first inclined lift rod and the first direction is A, and the angle between the second inclined lift rod and the first direction is B, satisfying A≥B+5°.

[0015] In the above scheme, since the angle between the first inclined lift rod and the first direction and the angle between the second inclined lift rod and the first direction satisfy the above relationship, on the one hand, it can be ensured that the first inclined lift rod and the second inclined lift rod have different ejection angles, thereby respectively exiting the undercuts at different angles, and on the other hand, the probability of interference and jamming between the first inclined lift block and the second inclined lift block during the process of exiting the undercut can be reduced.

[0016] Optionally, the number of the first inclined lift rods is two, the first inclined lift block includes a first body, a first side wall and a second side wall, the first side wall and the second side wall are both arranged on the same side of the first body and spaced apart from each other, the second ends of the two first inclined lift rods are respectively connected to the first side wall and the second side wall, and the second inclined lift block is arranged below the first body.

[0017] In the above scheme, the first side wall and the second side wall are located on the same side of the first body and are spaced apart from each other, thereby forming two fixed areas arranged at intervals. The first side wall and the second side wall are respectively connected to the second ends of the two first inclined lift rods. That is to say, the two first inclined lift rods are spaced apart on the same side of the first body and act on the first body together, reducing the probability of stress concentration in the first body. The second inclined lift block is arranged below the first body, which helps to reduce the probability of spatial interference between the second inclined lift block and the first inclined lift rod.

[0018] Optionally, the lower side of the first body has a first inclined surface, the upper side of the second inclined lift block has a second inclined surface, and the first inclined surface and the second inclined surface are in contact with each other.

[0019] In the above scheme, it can be understood that the first body and the second inclined lift block are fitted together by the first inclined surface and the second inclined surface, thereby reducing the probability of movement interference between the first body and the second inclined lift block when exiting the undercut, thereby ensuring that the first body and the second inclined lift block with different exit directions can be ejected smoothly respectively.

[0020] Optionally, the angle between the first inclined surface and the first direction is greater than the angle between the length direction of the first sliding groove and the first direction.

[0021] In the above scheme, since the angle between the first inclined surface and the first direction is greater than the angle between the length direction of the first slide groove and the first direction, it can ensure that the first body and the second inclined lift block are ejected smoothly, reducing the probability of movement interference between the first body and the second inclined lift block, thereby reducing the probability of the first body and the second inclined lift block being stuck.

[0022] Optionally, the angle between the first inclined surface and the first direction is C, and the angle between the length direction of the first sliding groove and the first direction is D, satisfying C≥D+3°.

[0023] In the above scheme, since the angle between the first inclined surface and the first direction and the angle between the length direction of the first slide groove and the first direction satisfy the above range, on the one hand, it ensures that the first body and the second inclined ejector block can be ejected along different directions respectively, and on the other hand, it can reduce the influence of motion errors and precision errors on the first inclined surface and the second inclined surface, thereby reducing the probability of jamming between the first body and the second inclined ejector block.

[0024] Optionally, the double-layer inclined lift mechanism further includes a first auxiliary inclined rod and a second auxiliary inclined rod, wherein the length direction of the first auxiliary inclined rod is parallel to the length direction of the first inclined lift rod, and the length direction of the second auxiliary inclined rod is parallel to the length direction of the second inclined lift rod;

[0025] One end of the first auxiliary diagonal rod in the length direction is fixed to the base plate, and the other end of the first auxiliary diagonal rod in the length direction is slidably set on the first slider. One end of the second auxiliary diagonal rod in the length direction is fixed to the base plate, and the other end of the second auxiliary diagonal rod in the length direction is set on the second slider.

[0026] In the above scheme, it can be understood that the first auxiliary diagonal rod and the second auxiliary diagonal rod can assist the first diagonal rod and the second diagonal rod in ejecting. On the one hand, it can reduce the vibration and shaking generated when the first diagonal rod and the second diagonal rod are subjected to force. On the other hand, the first auxiliary diagonal rod and the second auxiliary diagonal rod can disperse the load on the first diagonal rod and the second diagonal rod.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0049] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0050] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0053] The term "multiple" as used in the present application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0054] After the product is injected, the mold needs to be opened to remove the product. Since the injection molded part becomes hard after cooling, it is usually necessary to rely on the mold's ejection system to remove the product from the mold. This process usually involves the design and manufacture of the mold to ensure that the product can be separated from the mold smoothly.

[0055] The injection mold tilting mechanism is a conventional mechanism in the design of injection molds. The tilting mechanism is mainly used to form a product structure whose ejection direction is inconsistent with the main ejection direction. This product structure is commonly known as product undercut.

[0056] Conventional inclined ejector mechanisms can generally only form undercuts in the same demolding direction. For undercuts with multiple demolding directions, ordinary inclined ejector mechanisms cannot form the product.

[0057] When a product has two undercuts in two demoulding directions on the same mounting structure, that is, when the two undercuts overlap in the main demoulding direction of the mold, conventional inclined ejectors cannot form them.

[0058] In view of this, in order to demould the two undercuts that overlap in the main demoulding direction, the embodiment of the present application provides a double-layer inclined ejector mechanism, such as Figure 1 As shown, it includes a base plate 1, an ejector plate 2, a first inclined ejector rod 3, a second inclined ejector rod 4, a first inclined ejector block 5 and a second inclined ejector block 6.

[0059] The ejector plate 2 approaches or moves away from the bottom plate 1 along the first direction Z, and the first direction Z is parallel to the vertical direction. It can be understood that the ejector plate 2 and the bottom plate 1 produce relative movement. When the distance between the ejector plate 2 and the bottom plate 1 changes, a stable ejection process or reset process can be provided. Since the relative movement between the ejector plate 2 and the bottom plate 1 is carried out along a certain direction, it can ensure that the ejector can apply force smoothly and evenly during the ejection process, thereby avoiding damage to the product caused by uneven ejection force.

[0060] Please refer to Figure 2 , along the length direction of the first inclined push rod 3, that is, along the extension direction of the first inclined push rod 3, the first inclined push rod 3 has a first end 301 and a second end 302. It can be understood that the first end 301 and the second end 302 are respectively the two side ends of the first inclined push rod 3 along the length direction.

[0061] The first end 301 is located below the second end 302 , and the first end 301 is slidably disposed on the ejector plate 2 , that is, the first inclined ejector rod 3 is slidably connected to the ejector plate 2 through the first end 301 and can slide relative to the ejector plate 2 .

[0062] Please refer to Figure 3 and Figure 4 , along the length direction of the second inclined lift rod 4, that is, along the extension direction of the second inclined lift rod 4, the second inclined lift rod 4 has a third end 401 and a fourth end 402. It can be understood that the third end 401 and the fourth end 402 are respectively the two side ends of the second inclined lift rod 4 along the length direction.

[0063] The third end 401 is located below the fourth end 402 , and the third end 401 is movably disposed on the ejector plate 2 , that is, the second inclined ejector rod 4 is slidably connected to the ejector plate 2 through the third end 401 and can slide relative to the ejector plate 2 .

[0064] The first inclined ejector block 5 is arranged at the second end 302. It can be understood that the two side ends of the first inclined ejector rod 3 along its length direction are respectively connected to the first inclined ejector block 5 and the ejector plate 2. When the first inclined ejector rod 3 and the ejector plate 2 move relative to each other, the first inclined ejector block 5 at the other end of the first inclined ejector rod 3 also moves.

[0065] The second inclined lift block 6 is arranged at the fourth end 402. It can be understood that the two side ends of the second inclined lift rod 4 along its length direction are respectively connected to the second inclined lift block 6 and the ejector plate 2. When the second inclined lift rod 4 and the ejector plate 2 slide relative to each other, the second inclined lift block 6 at the other end of the second inclined lift rod 4 also moves.

[0066] The inclination angle of the first inclined ejector rod 3 relative to the first direction Z is different from the inclination angle of the second inclined ejector rod 4 relative to the first direction Z, that is, the inclination angles of the first inclined ejector rod 3 and the second inclined ejector rod 4 are different compared to the first direction Z, so that the first inclined ejector rod 3 and the second inclined ejector rod 4 slide along different inclination angles during ejection, so that the first inclined ejector rod 3 and the second inclined ejector rod 4 slide along different angles, thereby making the first inclined ejector block 5 and the second inclined ejector block 6 slide along different angles, thereby completing the demolding of two undercuts in different directions.

[0067] In the above scheme, the first inclined ejector rod 3 and the second inclined ejector rod 4 have different inclination angles respectively, so that when they slide along their respective inclination angles, they can complete the demoulding of undercuts in different directions. When the product has undercuts in two demoulding directions on the same mounting structure at the same time, the undercuts in the two demoulding directions can be demoulded by the first inclined ejector rod 3 and the second inclined ejector rod 4 respectively.

[0068] In other embodiments, the double-layer tilting mechanism further includes a first slide 7 and a second slide 8. The arrangement of multiple slides can provide ample layout space and reduce the probability of motion interference between the first sliding rod and the second sliding rod.

[0069] The first slide 7 is fixed to the ejector plate 2, please refer to Figure 5 The first slide seat 7 is provided with a first slide groove 701. It can be understood that the first slide groove 701 can provide a sliding space, thereby limiting the sliding range and guiding the sliding.

[0070] The first end 301 has a first slider 3011, and the first slider 3011 is slidably matched with the first slide groove 701, that is, the first end 301 is slidably connected to the first slide groove 701 through the first slider 3011, and the first slider 3011 slides in the first slide groove 701 to drive the first end 301 and the first inclined push rod 3 to move.

[0071] The second slide seat 8 is fixed to the ejector plate 2, and the second slide seat 8 is provided with a second slide groove 801. It can be understood that the second slide groove 801 can provide a sliding space, thereby limiting the sliding range and guiding the sliding.

[0072] The third end 401 has a second slider 4011, and the second slider 4011 slides in cooperation with the second sliding groove. That is, the third end 401 is slidingly connected to the second sliding groove 801 through the second slider 4011, and the second slider 4011 slides in the second sliding groove 801, thereby driving the third end 401 and the second inclined push rod 4 to move.

[0073] In the above scheme, when ejection is performed, the first slider 3011 drives the first inclined ejector rod 3 to slide through the first end 301, so that the first inclined ejector block 5 exits the undercut, and the second slider 4011 drives the second inclined ejector rod 4 to slide through the third end 401, so that the second inclined ejector block 6 exits the undercut.

[0074] The design of the slider and the slide makes the movement process smoother, which helps to reduce errors and wear caused by shaking or vibration.

[0075] In other embodiments, the length direction of the first slide groove 701 is perpendicular to the length direction of the first inclined push rod 3, that is, the extension direction of the first inclined push rod 3 is perpendicular to the length direction of the first slide groove 701, so that the first inclined push rod 3 can also move along the length direction of the first slide groove 701, so that the first inclined push rod 3 can move along the inclined direction.

[0076] The length direction of the second slide groove 801 is perpendicular to the length direction of the second inclined lift rod 4, that is, the extension direction of the second inclined lift rod 4 is perpendicular to the length direction of the second slide groove 801, so that the second inclined lift rod 4 can also move along the length direction of the second slide groove 801, so that the second inclined lift rod 4 can move along the inclined direction.

[0077] In the above scheme, the first inclined ejector rod 3 and the second inclined ejector rod 4 are guided by the first slide groove 701 and the second slide groove 801 respectively, and move along their respective inclined directions respectively, so as to realize demoulding with undercuts in different directions.

[0078] In some other embodiments, the angle between the first inclined lift rod 3 and the first direction Z is greater than the angle between the second inclined lift rod 4 and the first direction Z.

[0079] In the above scheme, the angle between the first inclined ejector rod 3 and the first direction Z is greater than the angle between the second inclined ejector rod 4 and the first direction Z, so that the movement of the first inclined ejector rod 3 in the horizontal direction is faster than the movement of the second inclined ejector rod 4 in the horizontal direction, so that the first inclined ejector rod 3 and the second inclined ejector rod 4 are demolded at different speeds respectively.

[0080] It can be understood that the downward slope angle of the first inclined lift rod 3 is greater than the downward slope angle of the second inclined lift rod 4, so that the first inclined lift block 5 can be separated from the product faster than the second inclined lift block 6, which helps to reduce the probability of interference between the first inclined lift block 5 and the second inclined lift block 6.

[0081] In other embodiments, the angle between the first inclined lift rod 3 and the first direction Z is A, and the angle between the second inclined lift rod 4 and the first direction Z is B, satisfying A≥B+5°.

[0082] In the above scheme, since the angle between the first inclined ejector rod 3 and the first direction Z and the angle between the second inclined ejector rod 4 and the first direction Z satisfy the above relationship, on the one hand, the first inclined ejector rod 3 and the second inclined ejector rod 4 can realize undercut demolding in different directions.

[0083] On the other hand, the first inclined lift block 5 can be separated from the product faster than the second inclined lift block 6, so that the speed at which the first inclined lift block 5 exits the undercut is greater than the speed at which the second inclined lift block 6 exits the undercut, and during the ejection process, the first inclined lift block 5 and the second inclined lift block 6 will gradually separate, reducing the probability of interference and jamming between the first inclined lift block 5 and the second inclined lift block 6 during the process of exiting the undercut.

[0084] In other embodiments, the number of the first inclined lift rods 3 is two. It can be understood that the two first inclined lift rods 3 can provide a stronger supporting force for the first inclined lift block 5, which helps to improve the overall stability and durability.

[0085] like Figure 6 As shown, the first inclined top block 5 includes a first body 501, a first side wall 502 and a second side wall 503. The first side wall 502 and the second side wall 503 are both arranged on the same side of the first body 501 and are spaced apart from each other. That is, the same side of the first body 501 is divided into at least three parts, including the first side wall 502 and the second side wall 503 spaced apart from each other, which helps to reduce stress concentration of the first body 501 and helps to maintain the stability of the first body 501.

[0086] The second ends 302 of the two first inclined lift rods 3 are respectively connected to the first side wall 502 and the second side wall 503, that is, the second ends 302 of the two first inclined lift rods 3 are respectively connected to the same side of the first body 501, and the second ends 302 of the two first inclined lift rods 3 are spaced apart on the same side of the first body 501.

[0087] At this time, the two first inclined push rods 3 respectively support the first body 501 on the same side of the first body 501 , thereby reducing the probability of stress concentration on the first body 501 and improving the stability of the first body 501 .

[0088] The second inclined lift block 6 is arranged below the first body 501, so that the second inclined lift block 6 can be moved from below the first body 501, which helps to reduce the movement interference between the first inclined lift block 5 and the second inclined lift block 6, thereby reducing the probability of movement interference between the first body 501 and the second inclined lift block 6 when exiting the undercut, thereby ensuring that the first body 501 and the second inclined lift block 6 with different exit directions can be ejected smoothly respectively.

[0089] In other embodiments, please refer to Figure 3 The lower side of the first body 501 has a first inclined surface 504, and the upper side of the second inclined top block 6 has a second inclined surface 601, and the first inclined surface 504 and the second inclined surface 601 are in contact with each other.

[0090] It can be understood that the first body 501 and the second inclined lift block 6 are connected by an inclined surface. At this time, when the first body 501 and the second inclined lift block 6 are ejected, the first body 501 and the second inclined lift block 6 can move along the second inclined surface 601 or the first inclined surface 504, thereby changing the relative position between the first body 501 and the second inclined lift block 6, thereby avoiding motion interference between the first body 501 and the second inclined lift block 6.

[0091] In some other embodiments, the angle between the first inclined surface 504 and the first direction Z is greater than the angle between the length direction of the first sliding groove 701 and the first direction Z.

[0092] It can be understood that since the angle between the first inclined surface 504 and the first direction Z is greater than the angle between the length direction of the first slide groove 701 and the first direction Z, it can ensure that the first body 501 and the second inclined lift block 6 move along the first inclined surface 504 to separate smoothly, thereby ensuring that the first body 501 and the second inclined lift block 6 are ejected smoothly.

[0093] In other embodiments, please refer to Figure 7 The angle between the first inclined surface 504 and the first direction Z is C, that is, the inclination angle of the contact surface between the first body 501 and the second inclined lift block 6 is C.

[0094] The included angle between the length direction of the first sliding groove 701 and the first direction Z is D, which satisfies C≥D+3°.

[0095] It can be understood that since the angle between the first inclined surface 504 and the first direction Z and the angle between the length direction of the first slide groove 701 and the first direction Z satisfy the above range, therefore, on the one hand, when the first body 501 and the second inclined lift block 6 are ejected, the first body 501 and the second inclined lift block 6 can move along the second inclined surface 601 or the first inclined surface 504, thereby changing the relative position between the first body 501 and the second inclined lift block 6, thereby avoiding motion interference between the first body 501 and the second inclined lift block 6.

[0096] On the other hand, a safety margin can be provided for the relative movement between the first body 501 and the second lift block 6, reducing the influence of debris obstruction or processing accuracy, thereby reducing the probability of jamming between the first body 501 and the second lift block 6, and ensuring smooth ejection of the first body 501 and the second lift block 6.

[0097] In other embodiments, Figure 8 As shown, the double-layer inclined lift mechanism also includes a first auxiliary inclined rod 9 and a second auxiliary inclined rod 10. It can be understood that the first auxiliary inclined rod and the second auxiliary inclined rod 10 can assist the movement of the first inclined lift rod 3 and the second inclined lift rod 4.

[0098] The length direction of the first auxiliary inclined rod 9 is parallel to the length direction of the first inclined ejector rod 3 . It can be understood that the first auxiliary inclined rod 9 and the first inclined ejector rod 3 which are parallel to each other can have the same ejection direction.

[0099] The length direction of the second auxiliary inclined rod 10 is parallel to the length direction of the second inclined ejector rod 4. It can be understood that the second auxiliary inclined rod 10 and the second inclined ejector rod 4 which are parallel to each other can have the same ejection direction.

[0100] One end of the first auxiliary diagonal rod 9 in the length direction is fixed to the base plate 1, and the other end of the first auxiliary diagonal rod 9 in the length direction is slidably set on the first slider 3011. That is, the first auxiliary diagonal rod 9 is fixed to the base plate 1, and the first auxiliary diagonal rod 9 can slide relative to the first slider 3011.

[0101] It can be understood that the first slider 3011 slides on the first auxiliary inclined rod 9, that is, the first slider 3011 drives the first inclined push rod 3 to move along the extension direction of the first auxiliary inclined rod 9. Since the length direction of the first auxiliary inclined rod 9 is parallel to the length direction of the first inclined push rod 3, the first slider 3011 can drive the first inclined push rod 3 to be ejected along the extension direction of the first inclined push rod 3.

[0102] One end of the second auxiliary diagonal rod 10 in the length direction is fixed to the base plate 1, and the other end of the second auxiliary diagonal rod 10 in the length direction is arranged on the second slider 4011, that is, the second auxiliary diagonal rod 10 is fixed to the base plate 1, and the second auxiliary diagonal rod 10 can slide relative to the second slider 4011.

[0103] It can be understood that the second slider 4011 slides on the second auxiliary inclined rod 10, that is, the second slider 4011 drives the second inclined push rod 4 to move along the extension direction of the second auxiliary inclined rod 10. Since the length direction of the second auxiliary inclined rod 10 is parallel to the length direction of the second inclined push rod 4, the second slider 4011 can drive the second inclined push rod 4 to be ejected along the extension direction of the second inclined push rod 4.

[0104] In another specific embodiment, the embodiment of the present application provides a double-layer inclined ejector mechanism, including a base plate 1, an ejector plate 2, a first inclined ejector rod 3, a second inclined ejector rod 4, a first inclined ejector block 5 and a second inclined ejector block 6.

[0105] The base plate 1 is fixedly provided with a first auxiliary diagonal rod 9 and a second auxiliary diagonal rod 10 . The length direction of the first auxiliary diagonal rod 9 is parallel to the length direction of the first diagonal rod 3 , and the length direction of the second auxiliary diagonal rod 10 is parallel to the length direction of the first diagonal rod 3 .

[0106] Along the length direction of the first inclined lift rod 3, the first inclined lift rod 3 has a first end 301 and a second end 302, and the first end 301 is located below the second end 302; along the length direction of the second inclined lift rod 4, the second inclined lift rod 4 has a third end 401 and a fourth end 402, and the third end 401 is located below the fourth end 402.

[0107] The ejector plate 2 approaches or moves away from the base plate 1 along a first direction Z, and the first direction Z is parallel to the vertical direction. The ejector plate 2 is fixedly provided with a first slide 7 and a second slide 8. The first inclined ejector rod 3 is slidably provided on the first slide 7, and the second inclined ejector rod 4 is slidably provided on the second slide 8, so that the first inclined ejector rod 3 and the second inclined ejector rod 4 can slide relative to the ejector plate 2.

[0108] The first end 301 has a first slider 3011, and the first slide seat 7 is provided with a first slide groove 701 cooperating with the first slider 3011; the third end 401 has a second slider 4011, and the second slide seat 8 is provided with a second slide groove 801 cooperating with the second slider 4011, providing multi-directional displacement for the first inclined ejector rod 3 and the second inclined ejector rod 4, ensuring that the first inclined ejector rod 3 and the second inclined ejector rod 4 can be ejected obliquely.

[0109] As an example, the first slider 3011 has two first sub-slide grooves, the first inclined push rod 3 and the first auxiliary inclined rod 9 are respectively slidably set in a first sub-slide groove, and the first slider 3011 is provided with a first sliding sheet on the side along the second direction, the second direction is perpendicular to the first direction Z, and the first sliding sheet is located between the first slide groove 701 and the first slider 3011.

[0111] The length direction of the first slide groove 701 is perpendicular to the length direction of the first inclined lift rod 3 , so that the first inclined lift rod 3 can move along the first slide groove 701 in a direction perpendicular to its own length direction.

[0112] The length direction of the second slide groove 801 is perpendicular to the length direction of the second inclined lift rod 4 , so that the second inclined lift rod 4 can move along the second slide groove 801 in a direction perpendicular to its own length direction.

[0113] The angle between the first inclined ejector rod 3 and the first direction Z is A, and the angle between the second inclined ejector rod 4 and the first direction Z is B, which satisfies A≥B+5°, so that the first inclined ejector rod 3 and the second inclined ejector rod 4 can respectively form undercut demolding in different directions.

[0114] The first inclined lift block 5 includes a first body 501, a first side wall 502 and a second side wall 503. The first side wall 502 and the second side wall 503 are both arranged on the same side of the first body 501 and are spaced apart from each other. The second ends 302 of the two first inclined lift rods 3 are respectively connected to the first side wall 502 and the second side wall 503. The second inclined lift block 6 is arranged below the first body 501, and the lower side of the first body 501 has a first inclined surface 504, and the upper side of the second inclined lift block 6 has a second inclined surface 601, and the first inclined surface 504 and the second inclined surface 601 are in contact with each other.

[0115] It can be understood that when the first body 501 and the second inclined ejector block 6 are ejected, the first body 501 and the second inclined ejector block 6 can slide relative to each other along the second inclined surface 601 and the first inclined surface 504 and finally separate.

[0116] The included angle between the first inclined surface 504 and the first direction Z is C, and the included angle between the length direction of the first sliding groove 701 and the first direction Z is D, which satisfies C≥D+3°.

[0117] Since the angle between the first inclined surface 504 and the first direction Z and the angle between the length direction of the first slide groove 701 and the first direction Z satisfy the above range, on the one hand, it is ensured that the first body 501 and the second inclined surface 601 and the first inclined surface 504 can slide respectively, and on the other hand, it can serve as a safety margin between the first body 501 and the second inclined surface 604 to reduce the probability of jamming between the first body 501 and the second inclined surface 6.

[0118] In another specific embodiment, the first inclined push rod 3 is provided with a plurality of first guide sleeves, and the first guide sleeves are slidably connected to the first inclined push rod 3, that is, the first inclined push rod 3 can slide in the first guide sleeves. It can be understood that the first guide sleeves can play a role in guiding the first inclined push rod 3.

[0119] The second inclined lift rod 4 is provided with a plurality of second guide sleeves, and the second guide sleeves are slidably connected to the second inclined lift rod 4, that is, the second inclined lift rod 4 can slide in the first guide sleeves. It can be understood that the second guide sleeves can play a role in guiding the second inclined lift rod 4.

[0120] The distances between the plurality of first guide sleeves and the plurality of second guide sleeves and the bottom plate 1 along the first direction Z are the same, and the plurality of first guide sleeves and the plurality of second guide sleeves are fixedly disposed in the core.
