Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a split-type inclined top seat structure and a mold. Background Technology

[0002] In mold forming technology, the angled ejector structure is a crucial part of product demolding, especially when dealing with products with undercuts, bosses, or recessed surfaces. While traditional integral angled ejector structures can meet demolding requirements to some extent, their limitations become increasingly apparent when dealing with small, precision, or complex molds. Conventional angled ejector seats are often directly locked to the mold's top plate. While this design is simple in mold manufacturing, it presents several problems in practical application. Particularly during screw tightening, the angled ejector seat is prone to rotation. This rotation not only leads to inaccurate positioning of the ejector seat but also affects the overall structure of the mold.

[0003] For high-precision molds in small spaces, the rotation problem of the ejector pin is particularly prominent. Due to the limited space in the mold, the installation position of the ejector pin is usually quite compact, and the rotation phenomenon will further aggravate the friction and interference between the ejector pin and other parts of the mold. During long-term use of the mold, this friction and interference can cause the ejector pin to jam or even break, seriously affecting the normal use of the mold and the production quality of the product. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a split-type inclined top seat structure and mold. By adding a fastening insert to the bottom of the inclined top seat and fixing the fastening insert by pressing, the rotation phenomenon that may occur when the inclined top seat screw is tightened is effectively avoided. This improvement not only reduces the risk of jamming and breakage, but also improves the service life and reliability of the inclined top seat mechanism.

[0005] The objective of this utility model is achieved through the following solution:

[0006] The first aspect of this utility model provides a split-type inclined ejector structure, which is disposed on the ejector plate of a mold. It includes an inclined ejector, a fastening insert, and a fixing block. The lower end of the inclined ejector passes through the ejector plate and is connected to the fastening insert. The upper end of the inclined ejector is connected to the inclined ejector block. The fastening insert is disposed in the ejector plate and has a retaining groove recessed at its upper end. The inclined ejector is provided with a retaining part that cooperates with the retaining groove. The retaining part is installed in the retaining groove. The fixing block is detachably installed at the bottom of the ejector plate and abuts against the lower surface of the fastening insert. The fixing block and the fastening insert are fixedly connected by fasteners.

[0007] Furthermore, the retaining groove is a T-shaped groove, and the retaining part is a T-shaped seat.

[0008] Furthermore, the upper surface of the fixing block is recessed with a limiting groove, and the fastening insert is sleeved in the limiting groove.

[0009] Furthermore, the bottom of the fastening insert is provided with a mounting hole, which is connected to the limiting groove.

[0010] Furthermore, the fixing block has a fixing hole that matches the mounting hole.

[0011] Furthermore, the fastener passes through the fixing hole and is screwed into the mounting hole.

[0012] A second aspect of this utility model provides a mold, including an upper mold plate, a lower mold plate, and an ejector plate. A cavity for molding a product is provided between the upper mold plate and the lower mold plate. The ejector plate is located below the lower mold plate. The mold also includes an inclined ejector block and a split inclined ejector seat structure as described above. The upper end of the inclined ejector seat passes through the lower mold plate and is movably connected to the inclined ejector block. The upper end of the inclined ejector block extends out of the upper surface of the lower mold plate. When the mold is closed, the inclined ejector block, the lower mold plate, and the upper mold plate together form the cavity.

[0013] Furthermore, the upper end of the inclined top seat is provided with an arc groove structure, and the inclined top block is sleeved in the arc groove structure.

[0014] Furthermore, a guide block is embedded in the lower template, which is used to guide the movement of the inclined top seat.

[0015] Furthermore, the guide block has a through hole, and the inclined top seat is disposed in the through hole.

[0016] The advantages of this invention are as follows: the addition of the fastening insert effectively avoids the rotation phenomenon that may be caused by the traditional screw locking method, and significantly enhances the stability and reliability of the inclined ejector mechanism; secondly, by pressing the insert between the ejector plate and the fixing block, not only is the fastening insert firmly installed on the ejector plate, but the installation process is also simplified. During high-frequency actions such as mold opening and closing and product ejection, the inclined ejector mechanism needs to withstand enormous pressure and friction. The use of the fastening insert makes the connection between the inclined ejector block and the inclined ejector seat tighter and more secure, thereby improving the load-bearing capacity and service life of the inclined ejector mechanism.

[0024] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0026] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0027] Please see Figure 1 , Figure 2A split-type inclined ejector structure is provided on the ejector plate 100 of a mold, including an inclined ejector 10, a fastening insert 20, and a fixing block 30. When the ejector plate 100 is driven, it will drive the inclined ejector 10 to move together, thereby realizing the ejection function of the inclined ejector. The lower end of the inclined ejector 10 passes through the ejector plate 100 and is connected to the fastening insert 20.

[0028] Please see Figure 3 , Figure 4 The fastening insert 20 is disposed within the ejector plate 100 and has a retaining groove 21 recessed at its upper end. The inclined ejector seat 10 is provided with a retaining part 11 that mates with the retaining groove 21. The retaining part 11 is installed within the retaining groove 21, which is a T-shaped groove, and the retaining part 11 is a T-shaped seat. The tight fit between the T-shaped groove and the T-shaped seat effectively prevents the fastening insert 20 from shifting or loosening under stress, thereby ensuring the stable operation of the inclined ejector mechanism. The fastening insert 20 is provided to prevent the inclined ejector seat 10 from being directly connected to the fastener 50, thereby effectively preventing breakage problems caused by stress concentration or material mismatch.

[0029] Please see Figure 4 The upper surface of the fixing block 30 is recessed with a limiting groove 31, and the fastening insert 20 is fitted into the limiting groove 31. When the fastening insert 20 is fitted into the limiting groove 31, the fit between the two becomes tight and stable. This connection method can not only effectively prevent the fastening insert 20 from shifting or loosening under force, but also ensure the stable operation of the inclined ejector mechanism during high-frequency actions such as mold opening and closing and product ejection.

[0030] Please see Figure 3 The fastening insert 20 has a mounting hole 22 at its bottom, which communicates with the limiting groove 31. The design of the mounting hole 22 allows for quick and easy fixing of the fastener 50 during installation. Because the mounting hole 22 communicates with the limiting groove 31, the fastener 50 can easily pass through the mounting hole 22 and be fixed at the bottom of the limiting groove 31, thus achieving a stable connection between the fastening insert 20 and the fixing block 30. The communication between the mounting hole 22 and the limiting groove 31 allows the fastener 50 to be embedded more deeply into the mold structure, thereby enhancing the stability of the connection.

[0031] Please see Figure 2 The fixing block 30 has a fixing hole 32 that matches the mounting hole 22. Through the matching of the fixing hole 32 and the mounting hole 22, the fastening insert 20 and the fixing block 30 are more firmly connected via the fastener 50. This connection method not only enhances the connection strength between the fastening insert 20 and the fixing block 30, but also improves the overall stability and load-bearing capacity of the mold.

[0032] The fixing block 30 is detachably mounted on the bottom of the ejector plate 100 and abuts against the lower surface of the fastening insert 20. The fixing block 30 and the fastening insert 20 are fixedly connected by a fastener 50. The fastener 50 passes through the fixing hole 32 and is screwed into the mounting hole 22. Preferably, the fastener 50 is a process screw, which achieves a firm fixation of the connector by means of the tightening action of the thread. When the fastener 50 passes through the fixing hole 32, its threaded portion will match the thread in the mounting hole 22. By rotating the fastener 50, it can be tightly screwed together with the mounting hole 22. This step not only achieves a firm connection between the fastening insert 20 and the fixing block 30, but also ensures the sealing and stability of the connection.

[0033] The fixing block 30 secures the fastening insert 20, ensuring that the fastening insert 20 can be stably pressed between the ejector plate 100 and the fixing block 30. The ejector plate 100 and the fixing block 30 are fixed by pressing the fastening insert 20 together. This fixing method eliminates the need for screw tightening, thus avoiding the rotation phenomenon that may occur when screws are tightened. This not only improves the stability of the angled ejector mechanism but also reduces the risk of jamming.

[0034] In addition, this utility model also provides a mold, please refer to [link / reference]. Figure 5 , Figure 6 The mold includes an upper mold plate, a lower mold plate 200, and an ejector plate 100. A cavity for forming a product is provided between the upper mold plate and the lower mold plate 200. The ejector plate 100 is located below the lower mold plate 200. The mold also includes an inclined ejector block 40 and a split inclined ejector seat structure as described above. The upper end of the inclined ejector seat 10 passes through the lower mold plate 200 and is movably connected to the inclined ejector block 40. The upper end of the inclined ejector block 40 extends out of the upper surface of the lower mold plate 200. When the mold is closed, the inclined ejector block 40, the lower mold plate 200, and the upper mold plate together form the cavity.

[0035] The upper end of the inclined ejector seat 10 is connected to an inclined ejector block 40. The upper end of the inclined ejector seat 10 has an arc-shaped groove structure 12, and the inclined ejector block 40 is fitted into the arc-shaped groove structure 12. The end of the inclined ejector block 40 near the inclined ejector seat 10 has an arc-shaped mounting platform 41. The inclined ejector and the inclined ejector seat 10 are connected via the arc-shaped mounting platform 41. This connection method not only ensures the stable installation of the inclined ejector on the inclined ejector seat 10 but also allows the inclined ejector to perform smooth reciprocating motion during ejection. During mold opening, the ejector plate 100 is subjected to an external driving force and begins to move upward. Since the inclined ejector seat 10 is connected to the ejector plate 100, the inclined ejector seat 10 also moves upward. Simultaneously, the inclined ejector block 40, driven by the inclined ejector seat 10, moves obliquely along the arc-shaped mounting platform 41, thereby achieving product ejection. When the mold closes, the ejector plate 100 is subjected to a reverse driving force and begins to move downward. The inclined base 10 and the inclined block 40 also move downwards, returning to their initial positions and completing the reset process.

[0036] A guide block 210 is embedded in the lower mold plate 200, which guides the movement of the inclined ejector 10. The guide block 210 is precisely embedded in the lower mold plate 200, and its main function is to guide the movement of the inclined ejector 10. During the reciprocating motion of the inclined ejector mechanism, the guide block 210 ensures that the inclined ejector 10 moves smoothly along a predetermined trajectory, avoiding mold damage or product defects caused by offset or wobbling. Through the guidance of the guide block 210, the movement trajectory of the inclined ejector 10 is strictly controlled, thereby improving the accuracy and stability of the mold.

[0037] The guide block 210 has a through hole 211, and the inclined top seat 10 is disposed within the through hole 211. The through hole 211 on the guide block 210 is a key channel for the installation and movement of the inclined top seat 10. The through hole 211 not only provides sufficient space for the inclined top seat 10 to ensure its smooth reciprocating motion, but also plays a guiding and positioning role. During the reciprocating motion of the inclined top mechanism, the inclined top seat 10 moves along the inner wall of the through hole 211 of the guide block. The inner wall of the through hole 211 plays a guiding and supporting role, ensuring that the inclined top seat 10 can move smoothly along a predetermined trajectory.

[0038] The lower mold plate 200 is fitted with a lower mold core 220, and the inclined ejector block 40 is installed in the lower mold core 220. Guided and supported by the lower mold core 220, precise positioning and stable movement are achieved, ensuring that the inclined ejector block 40 can accurately eject the product during the molding process without damaging the mold or the product. The inclined ejector block 40 is installed in an inclined hole within the lower mold core 220. When the mold is closed, the inclined ejector block 40 engages with the inclined hole. During injection molding, plastic material fills the mold cavity to form the product. When the mold opens, a thrust is applied to the inclined ejector block 40 from bottom to top, pushing it upwards a certain distance. Due to the engagement between the inclined ejector block 40 and the inclined hole, while moving upwards, the inclined ejector block 40 also moves a certain distance in the inclined direction, thus completing the undercut molding and demolding.

[0039] The split-type inclined ejector structure and mold provided by this utility model effectively avoid the rotation phenomenon that may be caused by the traditional screw locking method by adding a fastening insert 20, and significantly enhances the stability and reliability of the inclined ejector mechanism. Secondly, by pressing the insert between the ejector plate 100 and the fixing block 30, the fastening insert 20 is not only firmly installed on the ejector plate, but the installation process is also simplified. In high-frequency actions such as mold opening and closing and product ejection, the inclined ejector mechanism needs to withstand huge pressure and friction. The use of the fastening insert 20 makes the connection between the inclined ejector block 40 and the inclined ejector seat 10 tighter and more secure, thereby improving the load-bearing capacity and service life of the inclined ejector mechanism.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
