Description

Technical Field

[0001] This application relates to the field of injection molds, and in particular to a slanted ejector guide structure. Background Technology

[0002] In injection molds, angled ejector mechanisms are commonly used to achieve lateral demolding or to form undercut structures. Existing injection molds often employ angled ejector structures for lateral demolding. Traditionally, guides or wedges are only placed at the tail of the angled ejector, resulting in a lack of guidance in the front section near the cavity during ejection, forming a "suspended section." When the angled ejector angle is large or the ejector body is thin, this suspended section is prone to bending, affecting molding stability and lifespan.

[0003] To improve guidance, some solutions introduce angled ejector guides. These guides require guide holes or bushings coaxial with the guide rod and a complete stroke channel within the mold. This completed flow channel occupies a significant amount of mold space, restricts its placement, and hinders compact mold design and maintenance. Therefore, a stable, full-stroke guide structure for angled ejectors is needed. Utility Model Content

Detailed Implementation

[0018] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0020] This application provides a full-length inclined ejector guide structure for injection molds. The inclined ejector guide structure includes an inclined ejector, a sliding member, and a guide member. One end of the inclined ejector has a molding surface for contacting the molding surface of the plastic part. The sliding member is slidably connected to the other end of the inclined ejector along a first direction. The guide member is slidably connected to the sliding member along a second direction perpendicular to the first direction, and the guide member is in contact with and guides the inclined ejector.

[0021] The inclined top member is inclinedly disposed within the guide member, and the inclined top member slides along the first direction and the second direction to form an inclined movement, and during the inclined movement, the inclined top member is in contact with the guide member.

[0022] The inclined top full-length guide structure provided above is provided by the inclined top being inclinedly set inside the guide member, and by adopting two sets of mutually right-angled sliding cooperation, namely the inclined top sliding with the sliding member along the first direction and the sliding member sliding with the guide member along the second direction, to decompose the inclined ejection of the inclined top into orthogonal composite motion.

[0023] Meanwhile, by setting the tilting ejector to be in contact with the guide throughout the entire tilting motion, the tilting ejector is always constrained by the guide surface from ejection to reset, eliminating the "suspended section" at the front end. Lateral forces are continuously borne and straightened by the guide surface, reducing the bending risk of large-angle or thin tilting ejectors. Furthermore, it does not rely on additional guide rods and their channels, ensuring stable guidance throughout the entire process while reducing the space occupied within the mold.

[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] To facilitate understanding and assembly, this embodiment first establishes unified directions and terminology in the specification. The first direction refers to the linear sliding direction of the ejector relative to the sliding member, which is typically parallel to the side demolding direction of the product. The second direction refers to the linear sliding direction of the sliding member relative to the guide member, which is perpendicular to the first direction and typically parallel to the movement direction of the mold ejection mechanism. Tilt motion refers to the linear compound motion of the ejector relative to the guide member along a predetermined tilt trajectory. Contact with the guide refers to the sliding fit where the ejector maintains surface contact with the guide surface of the guide member throughout its entire stroke from the ejection start position to the reset position, continuously constraining the degrees of freedom of posture and providing bending resistance. The effect of the mold opening force or mold closing force in this embodiment is manifested by the linear driving force applied by the ejection mechanism and the reset mechanism. The ejection mechanism pushes the sliding member outward along the second direction, and the reset mechanism drives the sliding member back to its original position along the second direction.

[0026] Please see Figures 1-8 This application provides a slanted ejector guide structure 100 for injection molds. The slanted ejector guide structure 100 includes a slanted ejector 1, a sliding member 2, and a guide member 3. One end of the slanted ejector 1 has a molding surface 11 for contacting with the molding surface 11 of the plastic part. The sliding member 2 is slidably connected to the other end of the slanted ejector 1 along a first direction X. The guide member 3 is slidably connected to the sliding member 2 along a second direction Y perpendicular to the first direction X, and the guide member 3 is in contact with and guides the slanted ejector 1. The slanted ejector 1 is inclinedly disposed within the guide member 3. The slanted ejector 1 slides along the first direction X and the second direction Y to form an inclined movement, and during the inclined movement, the slanted ejector 1 is in contact with the guide member 3.

[0027] The inclined ejector 1 is disposed on the side of the mold cavity and forms a molding surface 11 at the front end that fits with the molding surface 11 of the plastic part. The inclined ejector 1 forms a sliding groove 12 at the rear end for cooperating with the sliding member 2. The outer surface of the inclined ejector 1 is machined into a mating surface that matches the guide surface of the guide member 3.

[0028] In this embodiment, it should be noted that the inclined top full-process guide structure 100 includes an inclined top component 1, a sliding component 2, and a guide component 3, which are assembled in sequence to form a spatial motion chain. The inclined top component 1 is an integral inclined surface component, with a forming surface 11 at its front end for engaging with the side wall or undercut part of the product, and a sliding groove 12, such as a dovetail or a T-shaped groove, at its rear end.

[0029] The sliding member 2 serves as a transitional connecting component. One side of it forms a sliding pair along the first direction X with the sliding groove 12 of the inclined top member 1, and the other side of its shape forms a sliding pair along the second direction Y with the sliding cavity 31 inside the guide member 3. The two sliding directions are orthogonal to each other.

[0030] The guide component 3 is a cavity-type part fixed on the template. The inner wall of the guide component 3 is machined to match the outer inclined surface of the inclined top component 1, with the inclination angle defined as α. The guide component 3 is positioned on the template in the first direction X by fasteners to ensure the stability of its inclined inner wall in space. During assembly, the inclined mating surfaces of the inclined top component 1 and the guide component 3 maintain surface contact throughout the entire stroke, with the sliding component 2 sandwiched between them, so that the first sliding pair and the second sliding pair respectively bear the axial and lateral relative displacement.

[0031] To ensure repeatability and durability of the motion, the mating surfaces of the inclined top component 1 and the guide component 3 are preferably treated with HRC5058 carburizing or nitriding, with a surface roughness Ra of 0.4-0.8 μm. The clearance between the first and second sliding pairs is preferably controlled between 0.01 and 0.03 mm.

[0032] The inner cavity of the guide member 3 has an annular or longitudinal oil groove in the area that contacts the sliding member 2, and the sliding member 2 has corresponding lubrication channels to maintain a stable oil film. To limit the limit stroke and prevent overshoot, an adjustable limiting mechanism such as a limiting screw / limiting block is provided between the rear end of the sliding member 2 and the template. The return stroke can be achieved by a return spring or a return hook.

[0033] During operation, the ejector mechanism applies force to the sliding member 2 along the first direction X, and the first sliding pair generates a relative displacement in the first direction X. Since the inclined ejector 1 and the guide member 3 are in full-range surface contact on the inclined surface, the inclined ejector 1 (1) is constrained to execute an inclined trajectory along the inclination angle α, while the second sliding pair provides the necessary lateral compensation displacement in the second direction Y. This motion can be characterized by vector decomposition: let the resultant ejection force be F, then the component force along the axis of the inclined ejector 1 (1) is F·cosα, and the component force along the side is F·sinα; the corresponding displacement relationship satisfies tanα=ΔY / ΔX.

[0034] Due to the superposition of the orthogonal sliding pairs and the full contact of the inclined surface, the inclined ejector 1 achieves a predetermined inclined trajectory within the limited mold cavity space, and there is no overhanging section at the front end. The force on the inclined ejector 1 is diverted and transmitted through the sliding member 2 and the guide member 3, significantly suppressing the risk of deflection caused by cantilever bending moment. Preferably, to enhance the resistance to eccentric load, the effective contact length between the inclined ejector 1 and the guide member 3 is not less than 70% of the total stroke at any working position. To reduce wear and creep, a small preload, such as an elastic baffle or a thin shim, can be provided between the sliding member 2 and the guide member 3 to eliminate initial clearance and stabilize the low-speed start-up friction state. This structure is compact, easy to assemble and disassemble, and suitable for molding scenarios with limited space and requiring lateral core pulling.

[0035] In one specific implementation, the guide member 3 has a sliding cavity 31 arranged along the second direction Y, the inclined top member 1 passes through the sliding cavity 31, the sliding cavity 31 encloses the sliding member 2, and the sliding member 2 is attached to and slidably connected with the sliding cavity 31.

[0036] In this embodiment, it should be noted that the guide member 3 is integrally provided with a sliding cavity 31 extending along the second direction Y. The sliding cavity 31 is a closed, fully enclosed structure, and its cross-section can be rectangular or near-rectangular with chamfered or rounded corners. The cavity length L x Matching the effective envelope length of slider 2, slider 2 is continuously covered by the inner wall of the cavity throughout its entire stroke. Slider 2 is a columnar or block-shaped component that fits into the cavity, and the two form a linear sliding pair along the second direction Y, retaining only the translational degree of freedom in the second direction Y.

[0037] The inclined top part 1 passes through the window (32) set by the guide part 3. The window (32) adopts the circumferential limit δ radial constraint on the outer contour of the inclined top part 1, so that the inclined top part 1 is always radially limited by the cavity wall during the compound motion, and maintains the straightness and repeatability of the motion trajectory of the inclined top part 1.

[0038] The guide member 3 also has an inclined groove 32, which communicates with the sliding cavity 31. The inclined ejector 1 is attached to and slidably connected with the inclined groove 32. The guide member 3 forms the sliding cavity 31 inside along the second direction Y. The guide member 3 forms the inclined groove 32 on the side near the inclined ejector 1. The guide member 3 opens an opening in the side wall of the sliding cavity 31 so that the inclined groove 32 and the sliding cavity 31 intersect and communicate in space. The inclined groove 32 forms an inclined angle C relative to the first direction X. The inclined angle C is preferably in the range of five to twenty-five degrees to balance demolding displacement and guiding length.

[0039] Specifically, the interconnected design of the inclined groove 32 and the sliding cavity 31 forms a dual-channel guide structure. The function of the inclined groove 32 is to provide a direct guide surface in the inclined direction for the inclined push member 1, supplementing the linear guiding limitation of the sliding cavity 31 through sliding contact with the surface of the inclined push member 1. The connection is such that the inclined groove 32 and the sliding cavity 31 are connected inside the guide member 3, and the inclined push member 1 simultaneously contacts the wall of the inclined groove 32 and the inner wall of the sliding cavity 31. Positionally, the inclined axis of the inclined groove 32 forms an angle with the axial direction of the sliding cavity 31, so that the inclined push member 1 is simultaneously subject to linear and rotational constraints during movement. The beneficial effect derived from this design is to reduce the pressure per unit area through multi-directional contact surfaces and guide the inclined push member 1 to move at a preset angle through the groove structure.

[0040] The inclined groove 32 is connected to the sliding cavity 31. The sliding direction of the sliding cavity 31 is opened along the second direction Y. The inclined groove 32 is inclined relative to the sliding cavity 31. The inclined groove 32 is used to generate the inclined movement of the inclined top member 1.

[0041] Specifically, the inclined setting of the inclined groove 32 relative to the sliding cavity 31 defines the motion trajectory of the inclined ejector 1 through geometric relationships. Its inclination angle C matches the designed demolding angle of the inclined ejector 1. Its function is to convert the lateral movement of the sliding component 2 into the composite displacement of the inclined ejector 1 through the constraint of the inclined surface of the groove wall. In terms of connection, the inclined groove 32 and the sliding cavity 31 form a continuous guide surface at their intersection. The positional relationship is controlled by the inclination angle of the inclined groove 32 to control the displacement of the inclined ejector 1 in the second direction Y. The beneficial effect derived from this structure is to reduce additional guide parts through the integrated groove structure and optimize the mold space utilization.

[0042] The sliding member 2 includes a slide rail 21 and a slot 22. The slide rail 21 is arranged along a first direction X, and the inclined top member 1 is attached to and slidably connected with the slide rail 21. The slot 22 is arranged along the first direction X, adjacent to the slide rail 21, and the inclined top member 1 is engaged with the slot 22, and the inclined top member 1 is attached to and slidably connected with the slot 22.

[0043] The slide rail 21 and the slot 22 of the slider 2 combine to form a bidirectional limiting structure. The slide rail 21 provides sliding guidance in the first direction X, while the slot 22 prevents the inclined top member 1 from rotating or disengaging during movement through sidewall constraints. In terms of connection, the slide rail 21 engages with the sliding groove 12 of the inclined top member 1, and the slot 22 engages with the flange of the inclined top member 1. In terms of position, the slide rail 21 and the slot 22 are arranged parallel and adjacent to each other, forming a coaxial double constraint. This design improves motion stability through mechanical interlocking, and is particularly suitable for long-stroke or high-acceleration scenarios.

[0044] The inclined top member 1 has a sliding groove 12 that matches the slide rail 21, and the sliding groove 12 slides along the slide rail 21.

[0045] The sliding groove 12 of the inclined top component 1 and the slide rail 21 are designed with high-precision fit tolerances. Their function is to reduce local stress and wear through surface contact. In terms of connection, the sliding groove 12 wraps around the slide rail 21 to form a sliding pair, and the positional relationship ensures coaxiality of movement through the axial overlap of the groove and rail. The beneficial effect derived from this structure is that it increases the guiding rigidity and wear resistance by increasing the contact area.

[0046] In the event of interference, the material passes through the sliding cavity 31 and enters the working area of ​​the inclined groove 32. The guide member 3 processes the guide surfaces on both sides of the inclined groove 32 into complementary planes to the outer contact surface of the inclined ejector 1. The guide member 3 processes the guide surfaces on both sides to a length not less than the sum of the effective ejection displacement of the inclined ejector 1 in the first direction X and the guide length, so as to ensure that the guide overlap length is always greater than zero throughout the entire stroke. The guide member 3 controls the surface roughness of the guide surfaces on both sides of the inclined groove 32 to be within the range of Ra0.4 to Ra0.8 micrometers, and performs heat treatment and fine grinding on the working surface to obtain stable friction characteristics and wear resistance.

[0047] The cross-sections of the sliding groove 12 and the slot 22 are snap-fit ​​surfaces, and the snap-fit ​​surfaces are complementary limiting snap-fit ​​shapes.

[0048] Specifically, the complementary cross-sectional shapes of the sliding groove 12 and the locking groove 22, such as T-shapes or trapezoids, form a mechanical interlock. This interlocking shape prevents the inclined pin 1 from disengaging from the sliding pin 2 under lateral force. The concave-convex fit of the cross-sectional shapes in the connection creates multi-dimensional constraints, while the symmetrical distribution of the shapes in the positional relationship ensures balanced force distribution. The beneficial effect derived from this design is improved system reliability through geometric locking.

[0049] The sliding member 2 also includes an abutting surface 23, which is located on the side opposite to the inclined ejector 1 along the first direction X, and abuts against the guide member 3 when the mold is closed during the tilting movement.

[0050] Specifically, the abutment surface 23 of the sliding member 2 is located on its bottom plane along the first direction X. This plane is ground to ensure a flatness of ≤0.01mm and maintains parallel fit with the corresponding abutment area at the bottom of the guide member 3's inner cavity. When the mold is closed, the abutment surface 23 forms rigid contact with the bottom surface of the guide member 3's inner cavity. At this time, the inclined ejector 1 is in its final working position, and its forming surface 11 and the mold cavity together constitute the plastic part forming space. The area of ​​the abutment surface 23 is optimized through finite element analysis and is usually designed to be 1.2-1.5 times the projected area of ​​the sliding member 2 to ensure uniform distribution of the mold closing locking force. In addition, the abutment surface 23 has a chamfered structure around its perimeter to avoid motion interference while guiding precise positioning during mold closing.

[0051] The rigid contact between the abutment surface 23 and the guide member 3 forms a mechanical stop at the mold closing endpoint, eliminating the cumulative stroke error that may exist in the hydraulic system or spring return, and ensuring that the positioning accuracy of the forming surface 11 of the inclined ejector 1 is stable within ±0.02mm. The mold closing force is directly transmitted to the body of the guide member 3 through the large-area abutment surface 23, avoiding crushing deformation caused by local stress concentration of the sliding member 2 in the traditional inclined ejector structure. The planar contact design between the abutment surface 23 and the guide member 3 can also serve as a cleaning surface, scraping off residual molten material during mold closing and preventing jamming. This structure is particularly suitable for molding scenarios of high-precision medical device molds.

[0052] The area of ​​the contact surface is denoted as A1, and the area of ​​the bottom surface of the sliding cavity is denoted as A2, satisfying the following relationship: A1 > A2.

[0053] In this embodiment, the working process is completed continuously in three stages: mold closing, ejection, and resetting. When the mold is in the closed state, the guide 3 is fixed on the mold fixing component, the slider 2 is located at the starting position of the sliding cavity 31, and the forming surface 11 of the inclined ejector 1 is in contact with the forming surface 11 of the cavity to form the side wall or undercut of the plastic part. The outer contact surface of the inclined ejector 1 and the inclined guide surface of the guide 3 form at least two mutually spaced surface contacts to establish the initial posture constraint. When the mold enters the ejection stage, the ejection mechanism pushes the slider 2 to move in and out of the sliding cavity 31 along the second direction Y. Under the cooperation of the sliding groove 12 and the slide rail 21, the inclined ejector 1 moves synchronously along the first direction X. At the same time, the inclined ejector 1 is geometrically constrained by the inclined guide surface and ejects at an angle along a straight line trajectory consistent with the inclination angle C. The inclined ejector 1 and the guide 3 maintain surface contact and sliding cooperation throughout the entire ejection stroke, and the guide surface continuously bears the lateral reaction force and straightening function. When the mold enters the reset stage, the reset mechanism drives the sliding member 2 back to the starting position along the second direction Y. Under the joint constraint of the sliding groove 12, the slide rail 21 and the inclined guide surface, the inclined ejector 1 returns to its original position along the reverse inclined trajectory. The forming surface 11 of the inclined ejector 1 re-attaches with the cavity forming surface 11 and completes the preparation for the next cycle.

[0054] Therefore, the inclined top full-range guide structure 100 provided above is inclinedly set inside the guide member 3 by the inclined top member 1, and adopts two sets of mutually right-angle sliding cooperation of the inclined top member 1 sliding with the sliding member 2 along the first direction X and the sliding member 2 sliding with the guide member 3 along the second direction Y, so as to decompose the inclined top ejection into an orthogonal composite motion.

[0055] Meanwhile, by ensuring that the inclined ejector 1 is in contact with the guide 3 throughout the entire tilting motion, the inclined ejector is always constrained by the guide surface from ejection to resetting, eliminating the "suspended section" at the front end. Lateral forces are continuously borne and corrected by the guide surface, reducing the bending risk of large-angle or thin inclined ejectors. Furthermore, it does not rely on additional guide rods or channels, ensuring stable guidance throughout the entire process while reducing the space occupied within the mold. The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
