Description

Technical Field

[0001] The invention relates to the field of injection molds and the technology, and in particular to a tilting ejector mechanism for solving product interference by using a movable insert and a use method thereof. Background Art

[0002] In the production of injection molded products, the undercut inside the product needs to be formed by a "lift" to shape the product structure. Due to the special shape and angle of some products, the lift will interfere with the product during movement. In actual production, the lift will scrape off the product, causing appearance defects. The lift mechanism includes a lift column and a lift piece. When demolding, the interference distance between the outer side of the lift piece and the top of the product is S1, such as Figure 1 As shown. At the same time, the plastic debris generated will get stuck in the gap of the mechanism movement, causing the mechanism movement to stagnate. Usually, the problem is solved by changing the direction of the lifter movement and modifying the product. However, modifying the product will change its appearance or assembly relationship, limiting the freedom of product design. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a tilting mechanism and a method of using the mechanism which can prevent interference with product demoulding and cause product damage, prevent mechanism jamming, and efficiently and simply solve product interference using movable inserts.

[0004] The technical solution of the present invention is achieved as follows: a tilted lift mechanism that uses a movable insert to solve product interference, includes a mold core, a tilted lift piece, a tilted lift column and a sliding assembly, the upper end of the mold core is provided with an opening, the tilted lift piece is arranged in the opening, the upper surface of the tilted lift piece is flush with the opening, and a hook forming cavity is formed between the molding surface of the tilted lift piece and the side wall of the mold core, the upper end of the tilted lift column passes through the mold core and is fixedly connected to the tilted lift piece, the lower end of the tilted lift column is connected to the sliding assembly, the tilted lift piece is provided with a first notch at the connection between the other side of the tilted lift piece relative to the hook forming cavity and the upper surface of the tilted lift piece, the first notch is provided with a movable insert that is slidably connected to the tilted lift piece, the movable insert is spaced apart from the bottom of the opening, the spacing part forms a movable stroke S2, a driving mechanism that drives the movable insert to move in the opposite direction relative to the movement direction of the tilted lift piece is provided between the movable insert and the mold core, and a guide limiting mechanism is provided between the movable insert and the tilted lift piece.

[0005] By adopting the above technical solution, the mold core, the inclined ejector, the inclined ejector column and the sliding assembly are included. The upper end of the mold core is provided with an opening, the inclined ejector is arranged in the opening, the upper surface of the inclined ejector is flush with the opening, so it is convenient for injection molding, and a barb molding cavity is formed between the molding surface of the inclined ejector and the side wall of the mold core. The upper end of the inclined ejector column passes through the mold core and is fixedly connected to the inclined ejector, and the lower end of the inclined ejector column is connected to the sliding assembly. The inclined ejector is provided with a first notch at the connection between the other side of the inclined ejector relative to the barb molding cavity and the upper surface of the inclined ejector The first notch is provided with a movable insert slidably connected with the inclined ejector. The initial position of the movable insert is that the upper surface of the movable insert, the upper surface of the inclined ejector and the upper surface of the mold core constitute a convex mold. When the convex mold and the concave mold are closed, the cavity at this time is connected with the barb molding cavity to form the cavity of the entire product. The movable insert is spaced apart from the bottom of the opening, and the spaced portion forms a movable stroke S2. The setting of the movable insert facilitates the decrease of the S2 value during demoulding. At this time, the convex injection molding surface generated by the inclined ejector and the movable insert is separated. At this time, no There will be interference problems. A driving mechanism is provided between the movable insert and the mold core to drive the movable insert to move in the opposite direction to the moving direction of the inclined ejector. The driving mechanism is provided to facilitate the downward movement of the movable insert during demoulding. A guide limiting mechanism is provided between the movable insert and the inclined ejector. The setting of the guide limiting mechanism can facilitate the upper surface of the movable insert, the upper surface of the inclined ejector and the upper surface of the mold core to form a punch, which can limit the maximum rising distance of the movable insert, facilitate injection molding, and greatly improve the efficiency of use. At the same time, it can improve the stability of the movement of the movable insert and prevent the generation of gaps. Since the movable insert and the mold collide to form a height difference when the mold is closed, a downward pulling force can be generated on the movable insert through the telescopic mechanism during demoulding, which effectively solves the interference problem of the product. At the same time, since there is no interference problem, no debris will fall into the gap to cause damage to the mechanism. The inclined ejector block is ejected 170mm, the angle is 18°, and the movement distance of the inclined ejector is: 170mm*tan18=55.2mm.

[0006] The present invention is further configured as follows: the driving mechanism includes a telescopic mechanism for driving the movable insert to move in the opposite direction to the moving direction of the inclined top piece and a boss for controlling the position of the movable insert relative to the inclined top piece, the telescopic mechanism includes a fixed column and a driving spring sleeved on the outer wall of the fixed column, one end of the fixed column is fixedly connected to the inclined top piece, the other end of the fixed column is inserted into the movable insert, a driving spring is sleeved on the outer side of the upper end of the fixed column, the upper end of the driving spring is fixedly connected to the fixed column, and the lower end of the driving spring is fixedly connected to the inside of the movable insert.

[0007] By adopting the above technical solution, the initial position of the movable insert is that the upper surface of the movable insert, the upper surface of the inclined top piece and the upper surface of the mold core form a convex mold. At this time, the bottom of the movable insert will conflict with the boss, and the driving spring of the telescopic mechanism will be compressed in the movable insert. The compression force will be released when the movable insert is separated from the boss during demolding. The driving spring will give the movable insert a downward force, which is convenient for shortening the movable stroke S2 ​​until the movable insert conflicts with the bottom of the first notch. Since S2>S1, the interference problem at S1 is solved at this time; the T-shaped setting of the fixed column , the end with a larger diameter faces the movable insert, the upper end of the driving spring is fixedly connected to the bottom of the end with a larger diameter of the fixed column, the movable insert includes a through hole for the fixed column to be inserted, and the lower end of the driving spring is fixedly connected to the inner wall of the through hole. Therefore, after the mold is closed, one end of the movable insert contacts the mold, and a height difference is formed between the movable insert and the first notch, that is, S2=3mm. The driving spring is pressed between the fixed column and the movable insert. When demolding, the driving spring provides a downward force to the movable insert, and the movable insert contacts the first notch. At this time, the value of S2 is 0.

[0008] The present invention is further configured as follows: the guide and limiting mechanism includes a first guide mechanism, which includes a guide rail arranged on the end surface of the inclined top piece facing the movable insert, and a first guide block is arranged on the end surface of the guide rail facing the movable insert, and a first sliding groove adapted to the first guide block is provided on the end surface of the movable insert facing the first guide block, and the first guide block is slidably connected to the first sliding groove along the movement direction of the movable insert relative to the inclined top piece.

[0009] By adopting the above technical scheme, since the movable insert slides on the inclined top, the setting of the guide limit mechanism can prevent the movable insert from generating a gap during the upward sliding movement or the movable insert from falling off during demolding, thereby improving the working stability. The setting of the first guide mechanism further improves the stability of the movable insert. The guide rail improves the stability of the sliding connection and prevents the generation of gaps. The upper end of the guide rail is connected to the bottom of the limit block, and the first guide block is fixedly connected to the guide rail. The setting of the first slide groove facilitates the sliding of the movable insert and improves the sliding efficiency. At the same time, it plays a limiting role, which is convenient for the formation of the injection molding punch.

[0010] The present invention is further configured as follows: a limit block is provided on the end surface of the inclined lift member facing the movable insert, and a second notch for contacting with the bottom of the limit block is provided on the end surface of the movable insert facing the inclined lift member.

[0011] By adopting the above technical solution, since the movable insert is slidably connected at the first notch, when the movable insert rises to the maximum height, the second notch will conflict with the limit block, which further plays a limiting role, facilitates injection molding, and greatly improves the efficiency of injection molding.

[0012] The present invention is further configured as follows: the guide and limiting mechanism also includes a second guide mechanism, which includes a second guide block and a limiting slide groove, one end of the second guide block is fixedly connected to the movable insert, and the other end is slidably connected to the limiting slide groove, and the limiting slide groove is arranged on the guide rail.

[0013] By adopting the above technical solution, the limiting slide groove is located on the guide rail, and one end of the second guide block is slidably connected to the limiting slide groove to facilitate the up and down movement of the movable insert, thereby improving the stability of the sliding connection. When the movable insert is in the initial state, the bottom of the movable insert cooperates with the boss to form a movable formation S2. When demolding, the movable insert needs to move downward, so the second guide mechanism plays a role in further improving the stability of the movement.

[0014] The present invention is further configured as follows: the boss is arranged at the bottom of the mold opening and is away from the side of the barb forming cavity, the top of the boss is in contact with the bottom of the movable insert, when the movable insert is in the mold closing state, the boss pushes the movable insert toward the mold opening, and the driving spring is in a compressed state; when the movable insert is in the mold opening state, the movable insert moves upward following the inclined ejector, and the movable insert moves downward under the action of the driving spring.

[0015] By adopting the above technical solution, the setting of the boss facilitates the formation of the initial state of the movable insert, thereby facilitating the injection molding of the injection molded product. Since the driving spring in the initial state is in a compressed state, when demolding, the driving spring will reset and give the movable insert a downward force, allowing the movable insert to move downward, thereby greatly improving the work efficiency.

[0016] A method for using a tilting lift mechanism that uses a movable insert to solve product interference includes the following steps:

[0017] a. When closing the mold, the outer side of the inclined ejector contacts the inner cavity of the mold, the side of the bottom of the movable insert away from the inclined ejector contacts the side of the inner cavity of the mold, the height of the movable insert rises, the second notch contacts the bottom of the limit block, and the top of the movable insert and the top of the inclined ejector form an injection surface, completing the mold closing;

[0018] b. During demoulding, the inclined ejector column moves toward the direction of the injection molded product, and the sliding assembly slides, and the inclined ejector begins to separate from the boss in the mold core. At this time, the movable insert descends through the telescopic mechanism;

[0019] c. The movable insert is separated from the injection molding surface formed by the inclined ejector, and the movable insert descends. The movable insert moves downward by a distance of S2;

[0020] d. At this time, the product interference value S1 is less than the distance S2 that the movable insert descends, and the demoulding work is successfully completed.

[0021] By adopting the above technical scheme, after the mold is closed, the bottom of the inclined top piece will conflict with the bottom of the mold cavity. A boss is provided on the side of the mold cavity close to the movable insert. After the inclined top piece is installed, the outer side of the bottom of the movable insert will conflict with the boss. At this time, a height difference S2 is formed between the bottom of the movable insert and the first notch. Since the second notch and the bottom of the limit block will conflict, that is, S2=3mm, the top of the movable insert and the top of the inclined top piece cooperate to form an injection surface for injection molding of the product. During the rising process of the movable insert, the guide limit mechanism and the telescopic mechanism play a role in stabilizing the rise of the movable insert and preventing the generation of gaps. After the injection molding of the product is completed, when demolding is performed, the inclined top piece moves along the direction of the inclined top column, and the inclined top piece begins to separate from the mold. At this time, the conflict between the movable insert and the boss is gradually eliminated. Under the action of the driving spring of the telescopic mechanism, the movable insert is subjected to a downward force and decreases. The value of S2 is greater than S1. Therefore, when the value of S2 is 0, the product interference problem is eliminated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 2 to 7As shown, the present invention discloses a tilting mechanism for solving product interference by using a movable insert, comprising a mold core 8, a tilting member 3, a tilting column 1 and a sliding assembly 2, wherein the mold core 8 is provided with an opening 9 at the upper end, and the tilting member 3 is arranged in the opening 9, and the upper surface of the tilting member 3 is flush with the opening 9, so as to facilitate injection molding, and a barb molding cavity is formed between the molding surface of the tilting member 3 and the side wall of the mold core 8, the upper end of the tilting column 1 passes through the mold core 8 and is fixedly connected to the tilting member 3, the lower end of the tilting column 1 is connected to the sliding assembly 2, and the tilting member 3 is connected to the other side of the barb molding cavity with respect to the tilting member 3. A first notch 301 is provided at the connection of the upper surface of the inclined ejector 3, and a movable insert 4 slidably connected to the inclined ejector 3 is provided at the first notch 301. The initial position of the movable insert 4 is that the upper surface of the movable insert 4, the upper surface of the inclined ejector 3 and the upper surface of the mold core 8 constitute a punch 7. When the punch 7 and the die are closed, the cavity at this time is connected to the barb molding cavity to form the cavity of the entire product. The movable insert 4 is spaced apart from the bottom of the opening 9, and the spaced portion forms a movable stroke S2. The setting of the movable insert 4 facilitates the decrease of the S2 value during demoulding. At this time, the inclined ejector 3 and The injection surface of the convex mold 7 generated by the movable insert 4 is separated, and there will be no interference problem at this time. A driving mechanism is provided between the movable insert 4 and the mold core 8 to drive the movable insert 4 to move in the opposite direction relative to the moving direction of the inclined ejector 3. The setting of the driving mechanism is convenient for the movable insert 4 to move downward during demoulding. A guide limiting mechanism 5 is provided between the movable insert 4 and the inclined ejector 3. The setting of the guide limiting mechanism 5 can facilitate the upper surface of the movable insert 4, the upper surface of the inclined ejector 3 and the upper surface of the mold core 8 to form the convex mold 7, which can limit the maximum rising distance of the movable insert 4 and is convenient for injection molding. , greatly improving the efficiency of use, and at the same time can improve the stability of the movement of the movable insert 4 and prevent the generation of gaps. Since the movable insert 4 and the mold are in conflict to form a height difference when the mold is closed, the telescopic mechanism 6 can generate a downward pulling force on the movable insert 4 during demoulding, which effectively solves the interference problem of the product. At the same time, since there is no interference problem, no debris will fall into the gap to cause damage to the mechanism. The inclined ejector block is ejected 170mm and the angle is 18°, so the inclined ejector movement distance is: 170mm*tan18=55.2mm.

[0033] The driving mechanism includes a telescopic mechanism 6 for driving the movable insert 4 to move in the opposite direction relative to the inclined ejector 3 and a boss 10 for controlling the position of the movable insert 4 relative to the inclined ejector 3. The telescopic mechanism 6 includes a fixed column 601 and a driving spring 602 sleeved on the outer wall of the fixed column 601. One end of the fixed column 601 is fixedly connected to the inclined ejector 3, and the other end of the fixed column 601 is inserted into the movable insert 4. The outer side of the upper end of the fixed column 601 is sleeved with a driving spring 602. The upper end of the driving spring 602 is fixedly connected to the fixed column 601, and the lower end of the driving spring 602 is fixedly connected to the inside of the movable insert 4. The initial position of the movable insert 4 is that the upper surface of the movable insert 4, the upper surface of the inclined ejector 3 and the upper surface of the mold core 8 constitute a punch 7. At this time, the bottom of the movable insert 4 will conflict with the boss 10, and the driving spring 602 of the telescopic mechanism 6 will be compressed in the movable insert 4. The compression force will cause the movable insert 4 to be demolded during demolding. When it is released from the boss 10, the driving spring 602 will give the movable insert 4 a downward force, which is convenient for shortening the movable stroke S2 ​​until the movable insert 4 and the bottom of the first notch 301 collide. Since S2>S1, the interference problem at S1 is solved at this time; the fixed column 601 is set in a T shape, with the end with a larger diameter facing the movable insert 4, the upper end of the driving spring 602 and the bottom of the end with a larger diameter of the fixed column 601 are fixedly connected, the movable insert 4 includes a through hole for the fixed column 601 to be inserted, and the lower end of the driving spring 602 is fixedly connected to the inner wall of the through hole. Therefore, after the mold is closed, one end of the movable insert 4 and the mold collide, and a height difference S2=3mm is formed between the movable insert 4 and the first notch 301. The driving spring 602 is pressed between the fixed column 601 and the movable insert 4. When demolding, the driving spring 602 provides a downward force for the movable insert 4, and the movable insert 4 will collide with the first notch 301. At this time, the value of S2 is 0.

[0034] The guide and limit mechanism 5 includes a first guide mechanism, which includes a guide track 501 arranged on the end surface of the inclined top member 3 facing the movable insert 4, and a first guide block 502 is arranged on the end surface of the guide track 501 facing the movable insert 4. The end surface of the movable insert 4 facing the first guide block 502 is provided with a first slide groove 401 adapted to the first guide block 502, and the first guide block 502 is slidably connected with the first slide groove 401 along the moving direction of the movable insert 4 relative to the inclined top member 3. Since the movable insert 4 slides on the inclined top, the setting of the guide and limit mechanism 5 can prevent the movable insert 4 from sliding. 4 generates a gap during the upward sliding movement or the movable insert 4 falls off during demoulding, which improves the working stability. The setting of the first guide mechanism further improves the stability of the movable insert 4. The guide track 501 improves the stability of the sliding connection and prevents the generation of gaps. The upper end of the guide track 501 is connected to the bottom of the limit block 302, and the first guide block 502 is fixedly connected to the guide rail. The setting of the first slide groove 401 facilitates the sliding of the movable insert 4, improves the sliding efficiency, and plays a limiting role, which is convenient for the formation of the injection punch 7.

[0035] A limit block 302 is provided on the end face of the inclined top piece 3 facing the movable insert 4, and a second notch 402 for abutting against the bottom of the limit block 302 is provided on the end face of the movable insert 4 facing the inclined top piece 3. Since the movable insert 4 is slidably connected at the first notch 301, when the movable insert 4 rises to the maximum height, the second notch 402 will abut against the limit block 302, which further plays a limiting role, facilitates injection molding, and greatly improves the efficiency of injection molding.

[0036] The guide and limiting mechanism 5 also includes a second guide mechanism, which includes a second guide block 503 and a limiting slide groove 504. One end of the second guide block 503 is fixedly connected to the movable insert 4, and the other end is slidably connected to the limiting slide groove 504. The limiting slide groove 504 is arranged on the guide rail 501, and the limiting slide groove 504 is located on the guide rail 501. One end of the second guide block 503 is slidably connected to the limiting slide groove 504 to facilitate the up and down movement of the movable insert 4, thereby improving the stability of the sliding connection. When the movable insert 4 is in the initial state, the bottom of the movable insert 4 cooperates with the boss 10 to form a movable formation S2. When demolding, the movable insert 4 needs to move downward, so the second guide mechanism plays a role in further improving the stability of the movement.

[0037] The boss 10 is arranged at the bottom of the opening 9 of the mold core 8 and is away from the boss 10 on the side of the barb molding cavity. The top of the boss 10 conflicts with the bottom of the movable insert 4. When the movable insert 4 is in the mold closing state, the boss 10 pushes the movable insert 4 toward the opening 9 of the mold core 8. At this time, the driving spring 602 is in a compressed state; when the movable insert 4 is in the mold opening state, the movable insert 4 moves upward following the inclined ejector 3, and the movable insert 4 moves downward under the action of the driving spring 602. The setting of the boss 10 facilitates the formation of the initial state of the movable insert 4, thereby facilitating the injection molding of the injection molded product. Since the driving spring 602 is in a compressed state in the initial state, the driving spring 602 will reset to give the movable insert 4 a downward force during demolding, so that the movable insert 4 moves downward, which greatly improves the work efficiency.

[0038] A method for using a tilting lift mechanism that uses a movable insert to solve product interference includes the following steps:

[0039] a. When closing the mold, the outer side of the inclined ejector contacts the inner cavity of the mold, the side of the bottom of the movable insert away from the inclined ejector contacts the side of the inner cavity of the mold, the height of the movable insert rises, the second notch contacts the bottom of the limit block, and the top of the movable insert and the top of the inclined ejector form an injection surface, completing the mold closing;

[0040] b. During demoulding, the inclined ejector column moves toward the direction of the injection molded product, and the sliding assembly slides, and the inclined ejector begins to separate from the boss in the mold core. At this time, the movable insert descends through the telescopic mechanism;

[0041] c. The movable insert is separated from the injection molding surface formed by the inclined ejector, and the movable insert descends. The movable insert moves downward by a distance of S2;

[0042] d. At this time, the product interference value S1 is less than the distance S2 that the movable insert descends, and the demoulding work is successfully completed.

[0043] Working principle: After the mold is closed, the bottom of the inclined ejector 3 will collide with the bottom of the mold cavity. A boss 10 is provided on the side of the mold cavity close to the movable insert 4. After the inclined ejector 3 is installed, the outer bottom of the movable insert 4 will collide with the boss 10. At this time, a height difference S2 is formed between the bottom of the movable insert 4 and the first notch 301. Since the second notch 402 and the bottom of the limit block 302 will collide, that is, S2 = 3mm, at this time, the top of the movable insert 4 and the top of the inclined ejector 3 cooperate to form an injection surface for the product to be injected. During the rising process, the guide limit mechanism 5 and the telescopic mechanism 6 play a role in stabilizing the rising of the movable insert 4 and preventing the generation of gaps. After the injection molding of the product is completed, when demoulding is performed, the inclined ejector 3 moves along the direction of the inclined ejector column 1, and the inclined ejector 3 begins to separate from the mold. At this time, the interference between the movable insert 4 and the boss 10 is gradually eliminated. Under the action of the driving spring 602 of the telescopic mechanism 6, the movable insert 4 is subjected to a downward force and falls. The value of S2 is greater than S1. Therefore, when the value of S2 is 0, the product interference problem is eliminated.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

When closing the mold, the outer side of the inclined ejector contacts the inner cavity of the mold, the side of the bottom of the movable insert away from the inclined ejector contacts the side of the inner cavity of the mold, the height of the movable insert rises, the second notch contacts the bottom of the limit block, and the top of the movable insert and the top of the inclined ejector form an injection surface, completing the mold closing; b. During demoulding, the inclined ejector column moves toward the direction of the injection molded product, and the sliding assembly slides, and the inclined ejector begins to separate from the boss in the mold core. At this time, the movable insert descends through the telescopic mechanism; c. The movable insert is separated from the injection molding surface formed by the inclined ejector, and the movable insert descends. The movable insert moves downward by a distance of S2; d. At this time, the product interference value S1 is less than the distance S2 that the movable insert descends, and the demoulding work is successfully completed.
