Description

Technical Field

[0001] This application relates to the field of product processing technology, and in particular to a mold ejection device. Background Technology

[0002] After injection molding, the product is typically ejected from the mold cavity using a direct ejection mechanism. However, after ejection, some parts of the product remain tightly bound to the direct ejection mechanism, requiring a secondary ejection mechanism to separate the product from it. This prevents damage from directly removing the product from the direct ejection mechanism. However, the secondary ejection mechanism not only increases production costs but also reduces production efficiency. Utility Model Content

[0003] This application provides a mold ejection device to solve the problem that setting a secondary ejection mechanism in the known technology leads to higher product production costs and lower production efficiency.

[0004] This application provides a mold ejection device, including a forming mold, an ejection assembly, a direct ejection assembly, and a locking / unlocking assembly; a molded part is formed in the forming mold; the ejection assembly is disposed on one side of the forming mold along a first direction, and the ejection assembly can move against the molded part along the first direction; one end of the direct ejection assembly is movably connected to the ejection assembly, and the other end of the direct ejection assembly is fitted into a receiving structure of the molded part to support the movement of the molded part; the locking / unlocking assembly has a defined locked state and an unlocked state. When the locking / unlocking assembly is in the locked state, the direct ejection assembly is fixedly connected to the ejection assembly through the locking / unlocking assembly; when the locking / unlocking assembly is in the unlocked state, the ejection assembly can move relative to the direct ejection assembly along the first direction.

[0005] In one possible implementation, the direct-acting assembly includes a guide and a direct-acting member, wherein the direct-acting member is slidably connected to the guide along the first direction; When the locking / unlocking component is in the locked state, the straight pusher slides relative to the guide; when the locking / unlocking component is in the unlocked state, the straight pusher is fixed relative to the guide through the locking / unlocking component.

[0006] In one possible implementation, the locking / unlocking component includes a movable member along a second direction, the movable member being movably connected to the straight abutment for switching between the locked state and the unlocked state, the second direction intersecting the first direction; When the movable component is in the locked state, it engages with the ejector assembly; when the movable component is in the unlocked state, it engages with the guide component.

[0007] In one possible implementation, the ejector assembly has a first guide groove, and the straight ejector is at least partially slidably disposed in the first guide groove along the first direction. The straight ejector also has a second guide groove, and the guide is at least partially slidably disposed in the second guide groove along the first direction. The first guide groove has a first snap-fit ​​groove on its groove wall, and the first end of the moving part can be snapped into the first snap-fit ​​groove. The outer peripheral surface of the guide part has a second snap-fit ​​groove, and the second end of the moving part can be snapped into the second snap-fit ​​groove.

[0008] In one possible implementation, the straight pusher has a groove extending through the outer peripheral surface of the straight pusher to the second guide groove along the second direction, and the movable part is slidably disposed in the groove.

[0009] In one possible implementation, the unlocking / unlocking assembly further includes a limiting member connected to the straight abutment member, the limiting member being configured to prevent the movable member from moving out of the groove.

[0010] In one possible implementation, the ejection assembly includes a top plate and a connector. Along the first direction, the top plate is disposed on one side of the molding die, the connector is connected to the top plate, and the connector has a first guide groove. Along the first direction, the straight ejector is at least partially slidably disposed within the first guide groove.

[0011] In one possible implementation, the mold ejection device further includes a drive assembly, which is tractively connected to the top plate and is used to drive the top plate to move along the first direction.

[0012] In one possible implementation, the ejection assembly further includes an ejector, one end of which is connected to the top plate, and the other end of which is used to resist movement of the molded part.

[0013] In one possible implementation, the molding die has a first through hole, and the straight ejector passes through the first through hole.

[0014] In the mold ejection device of this application, a locking / unlocking component is used to fix the straight ejector component and the ejection component together, so that the straight ejector component moves synchronously with the ejection component to eject the molded part from the mold. After the molded part is ejected from the mold, the locking / unlocking component releases the fixed connection between the straight ejector component and the ejection component, so that the ejection component continues to hold the molded part in place while the straight ejector component does not move with the ejection component, thereby separating the molded part from the straight ejector component. This achieves the separation of the molded part from the mold and the separation of the molded part from the straight ejector component solely through the action of the ejection component, eliminating the need for a secondary ejection structure to achieve the separation of the molded part from the straight ejector component. This reduces the cost of the mold ejection device and improves the ejection efficiency of the molded part. Attached Figure Description

[0025] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, an embodiment of this application provides a mold ejection device 100, including a forming mold 10, an ejection assembly 20, a direct ejection assembly 30, and an unlocking assembly 40.

[0027] For ease of reading, this application introduces a first direction Z, a second direction Y, and a third direction X to describe the embodiments of this application. The first direction Z, the second direction Y, and the third direction X can be three non-parallel straight lines in space; further, the first direction Z, the second direction Y, and the third direction X can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction Y is the Y-axis direction of the three-dimensional coordinate system, and the third direction X is the X-axis direction of the three-dimensional coordinate system.

[0028] Along the first direction Z, the molding die 10 has a first surface P1 and a second surface P2 disposed opposite to each other. The molding die 10 has a molding cavity 11, which is formed by recessing from the first surface P1 toward the second surface P2. A molded part can be formed within the molding cavity 11 by injection molding. Along the first direction Z, ejector components 20 are spaced apart on the side of the second surface P2 away from the first surface P1. Along the first direction Z, the ejector components 20 can abut against the molded part to push it out of the molding cavity 11. One end of a direct ejector component 30 is movably connected to the ejector component 20, and the other end of the direct ejector component 30 is fitted into a receiving structure of the molded part to abut against the movement of the molded part. The receiving structure can be a slotted structure or similar structure on the molded part, and one end of the direct ejector component 30 can extend into the slotted structure.

[0029] The locking / unlocking component 40 has defined locked and unlocked states. When the locking / unlocking component 40 is in the locked state, the direct ejector component 30 is fixedly connected to the ejector component 20 through the locking / unlocking component 40, so that the direct ejector component 30 and the ejector component 20 move synchronously to jointly eject the molded part from the molding cavity 11. When the locking / unlocking component 40 is in the unlocked state, the ejector component 20 can move relative to the direct ejector component 30 along the first direction Z, so that the direct ejector component 30 no longer moves with the ejector component 20.

[0030] Thus, in the mold ejection device 100 of this application, the straight ejector component 30 and the ejection component 20 are fixedly connected by the locking / unlocking component 40, thereby causing the straight ejector component 30 to move synchronously with the ejection component 20 to eject the molded part from the mold 10. After the molded part is ejected from the mold 10, the locking / unlocking component 40 releases the fixed connection between the straight ejector component 30 and the ejection component 20, allowing the ejection component 20 to continue to support the movement of the molded part, while the straight ejector component 30 does not move with the ejection component 20, thereby separating the molded part from the straight ejector component 30. This achieves the separation of the molded part from the mold 10 and the separation of the molded part from the straight ejector component 30 solely through the action of the ejection component 20, eliminating the need for a secondary ejection structure to achieve the separation of the molded part from the straight ejector component 30, reducing the cost of the mold ejection device 100, and improving the ejection efficiency of the molded part.

[0031] Please combine Figures 1 to 3 In one embodiment, the ejection assembly 20 includes a top plate 21 and a connector 22. Along the first direction Z, the top plate 21 is spaced apart on the side of the second surface P2 away from the first surface P1, and the top plate 21 can move closer to or further away from the molding die 10 along the first direction Z.

[0032] The connector 22 is disposed along the first direction Z, and one end of the connector 22 is connected to the side of the top plate 21 away from the molding mold 10. The connector 22 can be detachably connected to the top plate 21 by fasteners such as screws. It is understood that in other embodiments, the connector 22 can also be welded to the top plate 21 or connected by other structures such as snap-fit ​​structures.

[0033] The connector 22 has a first guide groove 220 extending through the end face of one end of the connector 22 to the end face of the other end along the first direction Z. The direct push assembly 30 is at least partially slidably disposed in the first guide groove 220 so that the direct push assembly 30 can slide relative to the connector 22 along the first direction Z.

[0034] In this embodiment, the ejection assembly 20 further includes an ejector 23, one end of which is connected to the top plate 21, and the other end of which is used to support the movement of the molded part. The end of the ejector 23 away from the top plate 21 can be inserted into a structure such as a hole or groove formed on the molded part to improve the stability of the ejector 23 when it pushes the molded part to move.

[0035] The molding die 10 has a second through hole (not shown in the figure), which connects to the molding cavity 11. The ejector 23 is inserted through the second through hole so that one end of the ejector 23 can pass through the second through hole and extend into the molding cavity 11, thereby supporting the molded part located in the molding cavity 11.

[0036] In this embodiment, the mold ejection device 100 further includes a base plate 50 and a drive assembly 60. The drive assembly 60 is a hydraulic lifting device or a lifting cylinder, etc., and the drive assembly 60 is connected to the top plate 21 for driving the top plate 21 to move along the first direction Z.

[0037] Along the first direction Z, the bottom plate 50 is located on the side of the top plate 21 away from the forming mold 10, and the driving component 60 is located on the side of the bottom plate 50 away from the top plate 21. The driving end of the driving component 60 can pass through the through hole opened in the bottom plate 50 and then connect to the top plate 21.

[0038] Please combine Figures 1 to 3 In one embodiment, the straight-push assembly 30 includes a guide 32 and a straight-push member 31. The straight-push member 31 is disposed along a first direction Z, and the straight-push member 31 includes a first straight-push member 311, a second straight-push member 312, and a third straight-push member 313 connected in sequence.

[0039] The first straight top 311 is at least partially slidably disposed within the first guide groove 220. A second guide groove 33 is formed at the end of the first straight top 311 away from the second straight top 312. A guide member 32 is disposed along the first direction Z, with one end connected to the base plate 50, specifically by fasteners such as screws. The other end of the guide member 32 is slidably disposed within the second guide groove 33, allowing the straight top member 31 to slide relative to the guide member 32, and guiding the straight top member 31 to slide along the first direction Z via the guide member 32. A guide hole 211 is formed in the top plate 21, extending through the top plate 21 along the first direction Z. The first straight top 311 passes through the guide hole 211, and the first straight top 311 slides within the guide hole 211.

[0040] One end of the second straight top 312 is detachably connected to the first straight top 311, specifically via fasteners such as screws. One end of the third straight top 313 is detachably connected to the second straight top 312, specifically via fasteners such as screws. The other end of the third straight top 313 is adapted to the receiving structure of the molded part, so that the end of the third straight top 313 away from the second straight top 312 extends into the receiving structure, ensuring stability during ejection of the molded part. The detachable connection between the third straight top 313 and the second straight top 312 allows for easy replacement of the third straight top 313.

[0041] The molding die 10 has a first through hole 12, a second straight top 312 passing through the first through hole 12, and a third straight top 313 connected to the second straight top 312 and extending out of the top of the first through hole 12. The first through hole 12 is arranged along the first direction Z and includes a first hole segment 121 and a second hole segment 122. The first hole segment 121 is formed by recessing from the second surface P2 of the molding die 10 toward the first surface P1. One end of the second hole segment 122 is connected to the first hole segment 121, and the other end is connected to the molding cavity 11. The diameter of the first hole segment 121 is larger than the diameter of the second hole segment 122, so as to form a second stepped surface P4 between the first hole segment 121 and the second hole segment 122. The second straight top 312 is inserted into the second hole section 122. The outer diameter of the first straight top 311 is greater than the outer diameter of the second straight top 312 and the hole diameter of the second hole section 122, and the outer diameter of the first straight top 311 is smaller than the hole diameter of the first hole section 121, so that the second step surface P4 can abut against the top of the first straight top 311 and restrict it from continuing to slide upward.

[0042] Furthermore, the guide hole 211 is a stepped hole, meaning it consists of two sections with different diameters to form a first stepped surface P3. Its specific structure can be found in the first through hole 12, and will not be described further here. The first vertical top 311 is located in the section of the guide hole 211 and its shape is adapted to fit the guide hole 211, so that the first stepped surface P3 can abut against the first vertical top 311 and apply downward pressure to it.

[0043] Thus, when the locking / unlocking component 40 is in the locked state, the first vertical top 311 is fixedly connected to the connector 22 via the locking / unlocking component 40, and the first vertical top 311 slides relative to the guide 32. When the locking / unlocking component 40 is in the unlocked state, the first vertical top 311 is fixed relative to the guide 32 via the locking / unlocking component 40, and the connector 22 slides relative to the first vertical top 311.

[0044] Please combine Figures 2 to 5 In one embodiment, the locking / unlocking assembly 40 includes a movable member 41 movably connected to a direct abutment 31 along a second direction Y, for switching between a locked state and an unlocked state. When the movable member 41 is in the locked state, it engages with the direct abutment 31; when the movable member 41 is in the unlocked state, it engages with the guide member 32.

[0045] The straight pusher 31 has a groove 34 extending through the outer peripheral surface of the straight pusher 31 along the second direction Y to the second guide groove 33. The movable member 41 is partially slidably disposed within the groove 34. The movable member 41 includes a moving part 411, a first end 412, and a second end 413. Along the second direction Y, the first end 412 and the second end 413 are integrally formed at opposite ends of the moving part 411. The first end 412 is disposed near the connector 22, and the second end 413 is disposed near the guide member 32.

[0046] The first end 412 and the second end 413 have the same structure, and both have an isosceles trapezoidal cross-sectional shape. Along the first direction Z, the opposite surfaces of the first end 412 and the second end 413 are inclined surfaces, respectively designated as a first inclined surface P5 and a second inclined surface P6. Along the first direction Z, the first inclined surface P5 is located below the second inclined surface P6. Along the second direction Y, the first inclined surface P5 extends downwards and obliquely toward the moving part 411, while the second inclined surface P6 extends upwards and obliquely toward the moving part 411.

[0047] The first guide groove 220 has a first engaging groove 221 on its groove wall. The shape and size of the first engaging groove 221 are adapted to the first end 412, and the first end 412 of the moving member 41 can be engaged in the first engaging groove 221. The first engaging groove 221 is located approximately in the area of ​​the connecting member 22 away from the top plate 21.

[0048] The guide member 32 has a second engaging groove 320 on its outer peripheral surface. The shape and size of the second engaging groove 320 are adapted to the second end 413, and the second end 413 of the moving member 41 can be engaged in the second engaging groove 320. The second engaging groove 320 is located approximately in the area of ​​the guide member 32 away from the bottom plate 50.

[0049] The first snap-fit ​​groove 221 has a third inclined surface P7 and a fourth inclined surface P8 on its groove wall. When the first end 412 is snapped into the first snap-fit ​​groove 221, the third inclined surface P7 abuts against the first inclined surface P5 of the first end 412, and the fourth inclined surface P8 abuts against the second inclined surface P6 of the first end 412. The second snap-fit ​​groove 320 has a fifth inclined surface P9 and a sixth inclined surface P10 on its groove wall. When the second end 413 is snapped into the second snap-fit ​​groove 320, the fifth inclined surface P9 abuts against the first inclined surface P5 of the second end 413, and the sixth inclined surface P10 abuts against the second inclined surface P6 of the second end 413.

[0050] Thus, when the molded part is formed in the molding cavity 11, the connecting member 22 is close to or abuts against the bottom plate 50. At this time, the first end 412 of the moving member 41 is located in the first snap-fit ​​groove 221. The driving assembly 60 drives the top plate 21 to move upward. The third inclined surface P7 abuts against the first inclined surface P5 and pushes the straight push member 31 to move upward synchronously. Then, the ejector 23 and the straight push member 31 push the molded part upward synchronously until the molded part leaves the molding cavity 11. In this process, since the third inclined surface P7 and the first inclined surface P5 are both inclined surfaces and form a wedge structure, when the connecting member 22 pushes the straight push member 31 upward, the connecting member 22 always applies a thrust to the first inclined surface P5 of the first end 412 along the second direction Y toward the guide member 32 through the third inclined surface P7, so that the second end 413 abuts against the outer surface of the area of ​​the guide member 32 where the second snap-fit ​​groove 320 is not opened.

[0051] When the molded part moves a certain distance away from the molding cavity 11, the second step surface P4 abuts against the first straight top 311 of the straight ejector 31, restricting the straight ejector 31 from moving further upward. At this time, the moving part 41 moves with the straight ejector 31 to the height of the second locking groove 320. Based on the thrust along the first direction Z applied by the third inclined surface P7 to the first inclined surface P5, the moving part 41 moves toward the guide 32 to the second end 413 and enters the second locking groove 320, while the first end 412 also disengages from the first locking groove 221. The drive assembly 60 continues to drive the top plate 21 to move upward, while the straight ejector 31 is supported by the guide 32 and no longer moves upward with the top plate 21. The molded part disengages from the straight ejector 31 under the pushing action of the ejector 23 of the top plate 21, thereby completing the demolding operation of the molded part.

[0052] After the molded part completes the demolding process, the drive assembly 60 drives the top plate 21 to descend. The top plate 21 descends until it abuts against the first vertical top 311 at the first step surface P3, thereby applying downward pressure to the first vertical top 311. At this time, the fifth inclined surface P9 applies a thrust to the first inclined surface P5 of the second end 413, moving it towards the guide member 32 in the second direction Y, thereby moving the moving member 41 until the first end 412 enters the first locking groove 221, while the second end 413 disengages from the second locking groove 320. Subsequently, the vertical ejector 31 moves downward with the top plate 21 to its reset position.

[0053] In this embodiment, there are two slide grooves 34, located on opposite sides of the first top edge 311 along the second direction Y. Correspondingly, there are also two first locking grooves 221 and two locking grooves 320.

[0054] It is understood that in other embodiments, the two slides 34 may also be disposed on opposite sides of the first top 311 along a third direction X. In this case, the moving member 41 moves within the slide 34 along a third direction X.

[0055] Please combine Figures 2 to 4 In one embodiment, the unlocking component 40 further includes a limiting member 42 connected to the straight abutment 31, and the limiting member 42 is configured to prevent the moving member 41 from moving to disengage from the slide 34.

[0056] Along the first direction Z, a mounting groove 35 is formed on the side of the slide 34 near the top plate 21, and one end of the limiting member 42 is fixed in the mounting groove 35. A limiting groove 4110 is formed on the moving part 411, and the other end of the limiting member 42 extends into the limiting groove 4110. Along the second direction Y, the length of the limiting groove 4110 is greater than the outer diameter of the limiting member 42, so that the limiting member 42 can move in the limiting groove 4110 along the second direction Y until the limiting member 42 moves to abut against the groove walls on opposite sides of the limiting groove 4110 in the second direction Y, and then the limiting member 42 abuts against the moving part 41 and restricts the moving part 41 from continuing to move.

[0057] In some embodiments, when the limiting member 42 abuts against the groove wall of the limiting groove 4110 on one side in the second direction Y, the first end 412 of the moving member 41 is located within the first engaging groove 221. When the limiting member 42 abuts against the groove wall of the limiting groove 4110 on the other side in the second direction Y, the second end 413 of the moving member 41 is located within the second engaging groove 320.

[0058] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
