Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a secondary forced release mechanism for a plastic flower pot base mold used in landscape engineering. Background Technology

[0002] In the field of landscape engineering, plastic flower pots are widely used due to their advantages such as light weight, low cost, and corrosion resistance. The flower pot base, as a key component for support and drainage, directly affects the construction quality and progress of landscape projects due to its structural integrity and production efficiency. Currently, plastic flower pot bases are mostly molded using injection molding. However, because flower pot bases for landscape engineering typically require complex structures such as reinforcing ribs, positioning clips, and multiple drainage holes, traditional molds face many problems in the demolding process: Traditional molds often use a single demolding structure (such as ejector pin ejection or integral core pulling), which easily leads to high demolding resistance, product deformation, and even mold jamming due to the concave and convex structures at the ends and sides of the flower pot base. Forced ejection can cause cracks at the base edges or breakage of reinforcing ribs, resulting in a high scrap rate. If multiple core pulling mechanisms are used, there are problems with poor structural linkage and insufficient synchronization, requiring multiple adjustments to ensure smooth demolding, seriously affecting production efficiency. Furthermore, traditional molds suffer from low positioning accuracy of the central forming component, which is prone to shifting after long-term use. This leads to deviations in the center hole of the flowerpot base, preventing precise alignment with the flowerpot body and further increasing assembly difficulty during construction. Therefore, there is an urgent need to design a secondary forced release mechanism for plastic flowerpot base molds used in landscape engineering that can overcome these defects.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a novel flowerpot mold [Application No.: 202010532937.9], which is composed of a base, an outer mold, an inner mold, and connecting bolts. The base is fixed to the ground, the outer mold is installed on the base, the inner mold is fitted inside the outer mold, and the connecting bolts pass through the center hole on the bottom surface of the inner mold and the outer mold, and are detachably connected to the base. However, this solution is still prone to problems such as high demolding resistance, product deformation, and even mold jamming during the demolding process. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a secondary forced release mechanism for plastic flowerpot base molds used in landscape engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A secondary forced release mechanism for a plastic flowerpot base mold used in landscape engineering includes a lower mold and an upper mold. An injection molding distributor is located above the upper mold. A central molding insert is located on the lower mold.

The limiting plate passes through the limiting abutment frame and the bottom of the locking head can abut against the top of the limiting abutment frame.

[0010] In the above-mentioned secondary forced release mechanism for plastic flower pot base molds used in landscape engineering, the side auxiliary forming structure includes two side auxiliary forming slides disposed between the lower mold and the upper mold of the flower pot base forming.

[0013] In the above-mentioned secondary forced release mechanism for plastic flower pot base molds used in landscape engineering, the transverse locking component includes a transverse locking plate disposed between the end auxiliary forming slide and the side auxiliary forming slide. One end of the transverse locking plate is engaged with the end auxiliary forming slide, and the other end is engaged with the side auxiliary forming slide.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, a secondary forced release mechanism for a plastic flowerpot base mold used in landscape engineering includes a lower mold 1 and an upper mold 2 for forming flowerpot bases. An injection molding distributor 3 is provided above the upper mold 2. A central forming insert 4 for the flowerpot base is provided on the lower mold 1. A slidable end auxiliary forming structure 5 and a side auxiliary forming structure 6 are provided between the lower mold 1 and the upper mold 2. The end auxiliary forming structure 5 and the side auxiliary forming structure 6 correspond in position and are shaped to the central forming insert 4. A transverse locking member 7 is provided between the end auxiliary forming structure 5 and the side auxiliary forming structure 6. One end of the transverse locking member 7 is engaged with the end auxiliary forming structure 5, and the other end is engaged with the side auxiliary forming structure 6. Limiting members 8 are provided at both ends of the lower mold 1 to limit the sliding stroke of the end auxiliary forming structure 5.

[0028] In this embodiment, during the injection molding process, the injection manifold 3 is fixed above the upper mold 2 of the flowerpot base molding and communicates with the injection channel of the upper mold 2; the flowerpot base center molding insert 4 is installed in the central area of ​​the lower mold 1 of the flowerpot base molding and forms a detachable connection with the lower mold 1; the end auxiliary molding structure 5 and the side auxiliary molding structure 6 are both disposed between the lower mold 1 and the upper mold 2 of the flowerpot base molding, and the two are distributed around the flowerpot base center molding insert 4, and the inner contour of the end auxiliary molding structure 5 and the inner contour of the side auxiliary molding structure 6 are matched with the outer contour of the flowerpot base center molding insert 4, together forming the flowerpot base. Cavity; lateral locking member 7 laterally connects the end auxiliary molding structure 5 and the side auxiliary molding structure 6, one end of which is snapped and fixed to the end auxiliary molding structure 5, and the other end of which is snapped and fixed to the side auxiliary molding structure 6; limiting member 8 is symmetrically arranged at both ends of the lower mold 1 for forming the flower pot base, and its position corresponds to the sliding trajectory of the end auxiliary molding structure 5. Through the combination of "upper and lower molds + center insert + sliding auxiliary molding structure", a complete molding space is provided for the flower pot base; lateral locking member 7 ensures that the auxiliary molding structure does not shift during mold closing and injection molding, ensuring the stability of the molding cavity shape; limiting member 8 prevents the auxiliary molding structure from sliding excessively during demolding, extending the service life of the mold.

[0029] Combination Figure 1-5 As shown, the end auxiliary forming structure 5 includes two end auxiliary forming slides 9 disposed between the lower mold 1 and the upper mold 2 of the flower pot base forming. The inner side of the end auxiliary forming slide has an end forming surface, which is directly opposite to the center forming insert 4 of the flower pot base. The two ends of the end auxiliary forming slide are attached to the side auxiliary forming structure 6.

[0030] Specifically, two end auxiliary forming slides 9 are symmetrically arranged at both ends of the center forming insert 4 of the flowerpot base, and are located between the lower forming mold 1 and the upper forming mold 2 of the flowerpot base; the inner side of the end auxiliary forming slides 9 is machined with an end forming surface that matches the end structure of the flowerpot base, and the end forming surface is directly opposite the end area of ​​the center forming insert 4 of the flowerpot base; the two side surfaces of the end auxiliary forming slides 9 are flat and fitting surfaces, which fit tightly with the end face of the side auxiliary forming structure 6 to ensure that there is no gap in the forming cavity.

[0031] The lower mold 1 for forming the flowerpot base is provided with an end inclined shaft 10 that passes through the end auxiliary forming slide 9. The end auxiliary forming slide 9 and the end inclined shaft 10 are in sliding cooperation.

[0032] In this embodiment, the end inclined shaft 10 is fixed to the lower mold 1 of the flowerpot base forming in an inclined state, and its inclined direction is consistent with the sliding direction of the end auxiliary forming slide 9. The end auxiliary forming slide 9 is provided with an inclined hole that matches the diameter of the end inclined shaft 10. The end inclined shaft 10 passes through the inclined hole, and the two form a sliding fit. The end auxiliary forming slide 9 can slide back and forth along the axial direction of the end inclined shaft 10. The inclined shaft guide design makes the sliding trajectory of the end auxiliary forming slide 9 more accurate and avoids jamming during the sliding process. Compared with the traditional linear guide rail, the inclined structure allows the slide to simultaneously "slide outward and lift upward" when demolding, reducing friction with the flowerpot base and reducing the risk of product scratches.

[0033] Combination Figure 3 , Figure 4 As shown, the limiting member 8 includes two limiting plates 11 disposed on the lower mold 1 for forming the flowerpot base. The outer side of the end auxiliary forming slide 9 is provided with a limiting abutment frame 12. The outer side of the limiting plate 11 has a locking head 13. The limiting plate 11 passes through the limiting abutment frame 12 and the bottom of the locking head 13 can abut against the top of the limiting abutment frame 12.

[0034] In this embodiment, two limiting plates 11 are symmetrically fixed at both ends of the lower mold 1 for forming the flowerpot base, perpendicular to the upper surface of the lower mold 1; the limiting abutment frame 12 is a rectangular frame structure, welded or bolted to the outer wall of the end auxiliary forming slide 9; the limiting plate 11 penetrates the interior of the limiting abutment frame 12, and the latch 13 on the outside of the limiting plate 11 is a barbed structure, the bottom of which forms a contactable limiting fit with the top of the limiting abutment frame 12 - when the end auxiliary forming slide 9 slides outward along the end inclined axis 10 to the maximum stroke, the bottom of the latch 13 abuts tightly with the top of the limiting abutment frame 12, preventing the slide from continuing to slide, accurately limiting the sliding stroke of the end auxiliary forming slide 9, avoiding the slide from colliding with other parts of the mold due to excessive sliding due to inertia, and ensuring that the reset position of the slide is consistent after each demolding, thus improving production stability.

[0035] The side auxiliary forming structure 6 includes two side auxiliary forming slides 14 disposed between the lower mold 1 and the upper mold 2 of the flower pot base forming. The side auxiliary forming slides 14 have a side forming surface on their inner side, and the side forming surface is directly opposite to the center forming insert 4 of the flower pot base.

[0036] In this embodiment, two side auxiliary molding slides 14 are symmetrically arranged on both sides of the center molding insert 4 of the flowerpot base, and together with the end auxiliary molding slides 9, they form a rectangular molding cavity periphery; the inner side of the side auxiliary molding slides 14 is machined with a side molding surface that matches the side structure of the flowerpot base, and the side molding surface is directly opposite the side area of ​​the center molding insert 4 of the flowerpot base.

[0037] Combination Figure 3As shown, the two ends of the side auxiliary forming slide 14 are in contact with the end auxiliary forming slide 9. The lower mold 1 for forming the flower pot base is provided with a side inclined shaft 15 that passes through the side auxiliary forming slide 14. The side auxiliary forming slide 14 and the side inclined shaft 15 are in sliding cooperation.

[0038] In this embodiment, the two end faces of the side auxiliary forming slide 14 are flat surfaces, which are tightly fitted with the two side faces of the end auxiliary forming slide 9 to form a sealed fit; the side inclined shaft 15 is fixed on the lower mold 1 of the flower pot base forming in an inclined state, and its inclined direction is consistent with the sliding direction of the side auxiliary forming slide 14; the side auxiliary forming slide 14 is provided with an inclined hole that matches the diameter of the side inclined shaft 15, and the side inclined shaft 15 passes through the inclined hole, and the two form a sliding fit - the side auxiliary forming slide 14 can slide back and forth along the axial direction of the side inclined shaft 15.

[0039] The side oblique axis 15 and the end oblique axis 10 are staggered.

[0040] In this embodiment, the staggered layout ensures that the end auxiliary molding slide 9 and the side auxiliary molding slide 14 do not interfere with each other when sliding, and can realize the sequential action of "side demolding first and rear demolding".

[0041] Combination Figure 1-5 As shown, the transverse locking member 7 includes a transverse locking plate 16 disposed between the end auxiliary molding slide 9 and the side auxiliary molding slide 14. One end of the transverse locking plate 16 is engaged with the end auxiliary molding slide 9, and the other end is engaged with the side auxiliary molding slide 14.

[0042] In this embodiment, the transverse locking plate 16 is a rectangular metal plate with a protruding buckle processed at one end. The side of the end auxiliary forming slide 9 is provided with a slot that matches the protruding buckle, and the two are fixed by a buckle-slot structure. The other end of the transverse locking plate 16 is also provided with a protruding buckle, and the side of the side auxiliary forming slide 14 is provided with a corresponding slot. The two are also fixed by a buckle-slot structure. One or two transverse locking plates 16 are provided between each end auxiliary forming slide 9 and the adjacent side auxiliary forming slide 14 to ensure locking strength.

[0043] Combination Figure 1-5 As shown, the lower mold 1 for forming the flowerpot base has a positioning protrusion 17 at its center, and the bottom of the center forming insert 4 of the flowerpot base is engaged with the positioning protrusion 17.

[0044] In this embodiment, the alignment protrusion 17 is a cylindrical or square protrusion structure, which is integrally formed with the lower mold 1 of the flowerpot base or bolted together; the bottom of the center molding insert 4 of the flowerpot base is provided with a positioning hole that matches the alignment protrusion 17, and the alignment protrusion 17 is inserted into the positioning hole to form an interference fit or a transition fit; the outer contour of the center molding insert 4 of the flowerpot base is designed according to the central structure of the flowerpot base, and different products can be adapted by replacing the insert with a different contour.

[0045] Combination Figure 1-5 As shown, the injection molding manifold 3 includes an injection molding main plate 18 and an injection molding manifold 19 disposed above the upper mold 2 for forming the flowerpot base.

[0046] In this embodiment, the injection molding main board 18 is fixed directly above the upper mold 2 for forming the flowerpot base. Its top is provided with an interface for connecting to the nozzle of the injection molding machine, and its bottom is bolted to the injection manifold 19. The injection manifold 19 has multiple manifold channels processed inside. One end of these manifold channels is connected to the main channel of the injection molding main board 18, and the other end is connected to multiple gates of the upper mold 2 for forming the flowerpot base, forming a complete injection path of "main channel-manifold channel-gate".

[0047] The working principle of this utility model is as follows:

[0048] During mold closing, the upper mold 2 for forming the flowerpot base moves downward and closes with the lower mold 1 for forming the flowerpot base. During this process, the end auxiliary forming slide 9 slides inward along the end inclined axis 10, and the side auxiliary forming slide 14 slides inward along the side inclined axis 15 until the two are tightly fitted together, forming a closed molding cavity around the center molding insert 4 of the flowerpot base. The two ends of the transverse locking plate 16 are respectively engaged with the slots of the end auxiliary forming slide 9 and the side auxiliary forming slide 14, locking the auxiliary forming structure as a whole to prevent displacement. The injection molding machine delivers molten plastic to the injection manifold 19 through the injection main plate 18. The plastic is distributed to each gate of the molding cavity through the manifold channel, filling the molding cavity. Subsequently, the cooling system cools the molding cavity (cooling temperature controlled at 40-60℃), and the plastic solidifies to form the flowerpot base blank.

[0049] During demolding, the upper mold 2 of the flowerpot base molding opens upward and separates from the lower mold 1; the injection molding manifold 3 rises synchronously with the upper mold 2, detaching from the flowerpot base blank; the mold drive mechanism (such as a cylinder or hydraulic cylinder) drives the transverse locking plate 16 to move outward, causing the latches at both ends to disengage from the slots of the end auxiliary molding slide 9 and the side auxiliary molding slide 14, completing the unlocking; the side auxiliary molding slide 14, driven by the drive mechanism, slides outward along the side inclined axis 15, and its side molding surface detaches from the side structure of the flowerpot base blank, completing the "first strong demolding"—this step prioritizes the removal of the side reinforcing ribs to avoid interference during subsequent end sliding; during the second demolding, the end auxiliary... Driven by the driving mechanism, the auxiliary forming slide 9 slides outward along the end inclined axis 10. When it slides to the maximum stroke, the locking head 13 of the limiting plate 11 abuts against the top of the limiting abutment frame 12, and the slide stops sliding. Its end forming surface is completely separated from the end structure of the flower pot base blank, completing the "secondary forced removal". The ejection mechanism (such as ejector pin or top plate) in the lower mold 1 of the flower pot base moves upward and ejects the flower pot base blank from the center forming insert 4 of the flower pot base. The worker or robot takes away the product. The driving mechanism drives the end auxiliary forming slide 9 and the side auxiliary forming slide 14 to reset, and the transverse locking plate 16 re-locks and enters the next production cycle.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.

[0051] Although this document frequently uses terms such as lower mold for flowerpot base forming 1, upper mold for flowerpot base forming 2, injection molding manifold 3, center molding insert for flowerpot base 4, end auxiliary molding structure 5, side auxiliary molding structure 6, transverse locking component 7, limiting component 8, end auxiliary molding slide 9, end inclined shaft 10, limiting plate 11, limiting abutment frame 12, locking head 13, side auxiliary molding slide 14, side inclined shaft 15, transverse locking plate 16, alignment protrusion 17, injection main plate 18, and injection manifold 19, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
