Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to an injection mold. Background Art

[0002] An injection mold is a tool used in the injection molding process, mainly for producing plastic parts. The injection mold heats the plastic material to a molten state and then injects it into the mold to cool and solidify, finally forming a plastic part with the required shape. For some complex plastic parts, a core-pulling mold needs to be set up. The core is inserted into the mold cavity. After injection molding, the core is then pulled out by pulling it out of the deep groove or inner cavity of the plastic part.

[0003] For plastic parts with grooves and slots having a relatively large depression angle on the same surface, straight extraction will damage the arc surface of the molded part. Core pins for oblique insertion and lateral insertion need to be set up, and the slider that drives the core pin to move is prone to interference when inserting and pulling out. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an injection mold, which solves the problem that interference will occur during the oblique and straight core-pulling actions on the same side of the injection molded part, and can realize the function of the mold to first extract the straight core pin and then obliquely extract the core pin.

[0005] The technical solution of the utility model: An injection mold, including an upper mold, a lower mold, and a bottom plate for fixing the lower mold. An insert is arranged on the lower mold. The upper mold and the lower mold form a mold cavity. A ejection structure is arranged on the lower mold. An injection port is arranged on the upper mold. A runner is communicated between the injection port and the mold cavity. It also includes an inclined slider that can move obliquely relative to the horizontal plane and a straight slider that can move horizontally relative to the inclined slider. The inclined slider is slidably arranged on the insert. The inclined slider includes an inclined core pin that can extend into the mold cavity. The straight slider is fixedly connected with a straight core pin that can extend into the mold cavity. A sliding member one for driving the inclined slider to move and a sliding member two for driving the straight slider to move are fixedly arranged on the upper mold;

[0006] An inclined hole for passing through the sliding member one is arranged on the inclined slider. The sliding member one and the end surface of the inclined hole close to or away from the mold cavity are inclined downward. The distance between the inclined end surfaces of the inclined hole is greater than the distance between the inclined end surfaces of the sliding member one.

[0007] With the above technical solution, the first sliding member and the second sliding member fixedly arranged on the upper mold respectively control the inclined sliding block and the straight sliding block, and the first sliding member and the second sliding member are jointly controlled by the opening and closing actions of the upper mold, converting the opening and closing actions into the actions of the inclined sliding block and the straight sliding block, enabling the mold to realize the extraction or insertion of the mold core during the demolding and closing processes, and the inclined sliding block and the straight sliding block move synchronously. At the same time, due to the gap between the inclined hole and the first sliding member, the straight sliding block moves a longer distance than the inclined sliding block. After the straight sliding block moves out during demolding, the inclined sliding block and the straight sliding block can then jointly extract the injection molded part together, avoiding damage to the injection molded part when the inclined sliding block drives the straight sliding block to move obliquely downward. During closing, the inclined sliding block and the straight sliding block are inserted together. After the inclined sliding block reaches the position, the straight sliding block can still move a certain distance, realizing non-interfering actions of the inclined sliding block and the straight sliding block, and the overall control is smooth.

[0008] A further setting of the present utility model: The second sliding member is provided with a T-shaped card slot, and the end faces of the T-shaped card slot facing the mold cavity are all inclined downward. The straight sliding block is provided with a T-shaped portion that is slidably engaged with the T-shaped card slot.

[0009] With the above further setting, the T-shaped portion is fitted and clamped in the T-shaped card slot and can only slide along its inclined surface. When the second sliding member is controlled by the upper mold to move upward, the inclined surface of the T-shaped card slot presses the T-shaped portion, and the T-shaped portion moves along the inclined surface in a direction away from the mold cavity, realizing the action of extracting the straight sliding block; similarly, when the second sliding member is controlled by the upper mold to move downward, the T-shaped portion moves along the inclined surface in a direction close to the mold cavity, realizing the action of inserting the straight sliding block inward.

[0010] A further further setting of the present utility model: The inclined surface of the T-shaped card slot is parallel to the inclined end surface of the first sliding member.

[0011] With the above further further setting, the inclined surface of the T-shaped card slot and the inclined end surface of the first sliding member have the same inclination angle with respect to the horizontal plane. When the inclined sliding block and the straight sliding block move synchronously, the upper mold action controls the inclined sliding block and the straight sliding block to displace the same distance, ensuring synchronous movement.

[0012] A further setting of the present utility model: A sinking groove for arranging the straight sliding block is provided on the end surface of the inclined sliding block away from the mold cavity, and the straight mold core passes through the inclined sliding block and the first sliding member and extends into the mold cavity.

[0013] With the above further setting, the straight sliding block can be arranged inside the inclined sliding block. While constructing the mold cavity structure, the internal structure of the mold is made compact, saving material costs.

[0014] A further setting of the present utility model: A buffer structure is provided between the inclined sliding block and the straight sliding block. The buffer structure includes V-shaped grooves provided on the left and right sides of the straight sliding block and V-shaped members provided on the inclined sliding block through springs. The V-shaped members can be clamped in the V-shaped grooves.

[0015] With the above further settings, a buffer structure is provided between the straight slider and the inclined slider. The V-shaped part is always pressed against the left and right sides of the straight slider by the spring. After the straight slider moves a certain distance relative to the inclined slider, the V-shaped part is clamped in the V-shaped groove to realize the synchronous movement of the straight slider and the inclined slider. Only after the inclined slider reaches the position during the final mold closing, the second sliding part continues to move downward to push the straight slider to move. At this time, the force exerted on the straight slider by the second sliding part in the moving direction is greater than the force exerted on the straight slider by the spring extrusion of the V-shaped part in the moving direction, causing the V-shaped part to leave the V-shaped groove and continue to extend. Thus, the buffer structure ensures that the straight slider and the inclined slider can be synchronously linked and can move independently.

[0016] A further setting of the present utility model: It further includes an upper fixing seat, a top plate, and a base. The upper fixing seat, the top plate, the upper mold, the lower mold, the bottom plate, and the base are arranged in sequence from top to bottom. A guide pillar is penetrated and arranged between the upper fixing seat and the bottom plate. The lower mold and the bottom plate are positioned by positioning columns and positioning sleeves, and the upper mold and the lower mold are connected by arranging nylon hooks.

[0017] With the above further settings, the positions of various parts of the mold are positioned by the guide pillar, and it can move along the direction of the guide pillar to realize the actions of demolding and mold closing. The position of the lower mold is positioned by the positioning column and the positioning sleeve, and the upper mold and the lower mold are closed by using the nylon hook, so that only when the mold opening force is greater than the expansion force of the nylon hook can the upper mold and the lower mold be separated.

[0018] A further setting of the present utility model: The ejection structure includes an ejector pin bottom plate and an ejector pin fixing plate arranged between the bottom plate and the base. The ejector pin fixing plate is provided with a product ejector pin and a runner ejector pin. The ejector pin bottom plate is arranged below the ejector pin fixing plate to push the product ejector pin and the runner ejector pin, and a reset part is arranged between the ejector pin fixing plate and the bottom plate.

[0019] With the above further setting, the product ejector pin and the runner ejector pin are arranged below the insert, and are evenly distributed below the injection molded part and the injection runner respectively, as part of the auxiliary injection of the mold cavity. When the ejector pin bottom plate is pushed by an external push rod, the ejector pin fixing plate drives the product ejector pin and the runner ejector pin to move upward respectively to eject the injection molded part and the injection runner to realize demolding. After demolding, the external push rod retracts, and the product ejector pin and the runner ejector pin are reset under the action of the reset part.

[0020] A further setting of the present utility model: Waterway pipes for cooling the runner and the mold cavity are penetrated in the top plate, the upper mold, and the lower mold.

[0021] With the above further setting, by arranging the waterway pipes, it can be ensured that during the injection molding process, the injection runner and the injection mold cavity can be cooled by water flow, accelerating the cooling and molding of the injection molded part and ensuring the quality of the injection molded product.

[0033] The technical solutions in the present embodiment will be clearly and completely described below in conjunction with the accompanying drawings.

If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, in the present invention, the descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0036] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0037] As Figure 1-10 shown, an injection mold includes an upper mold 1, a lower mold 2, and a bottom plate 17 for fixing the lower mold 2. A ejection structure is provided below the lower mold 2. An injection port is provided on the upper mold 1. An insert 21 is provided on the lower mold 2. The insert 21 includes two symmetrically arranged fixed mold cores and two symmetrically arranged inclined sliders 3. Each inclined slider 3 has an inclined core 31 near the center. The upper mold 1, the insert 21, and the two fixed mold cores and the inclined core 31 form a mold cavity 5. The injection port is communicated with the mold cavity 5 through an injection runner.

[0038] The inclined sliders 3 are slidably arranged on the insert 21. The sliding surface 211 of the insert 21 in contact with the inclined sliders 3 is inclined towards the bottom of the mold cavity 5, and a chute 212 with the same inclination angle as the sliding surface 211 is provided for the side protrusions of the inclined sliders 3 to slide in, so that the inclined sliders 3 can slide obliquely relative to the horizontal plane, enabling the inclined core 31 to be demolded obliquely and avoiding damaging the injection molded part.

[0039] To meet the requirement of constructing the cavity structure, a sunk groove 32 is formed on the end face of the inclined slider 3 away from the cavity 5. A straight slider 4 is arranged in the sunk groove 32. A straight insert core 41 is clamped on the straight slider 4. The straight insert core 41 passes through the inclined slider 3 and the first sliding member 6 and extends into the cavity 5. The straight slider 4 is directly arranged inside the inclined slider 3 and can move linearly along the horizontal plane relative to the inclined slider 3. The internal structure of the mold is compact, saving material costs. The straight insert core 41 and the injection molded part with holes at the injection molding part inserted horizontally into the cavity 5 need to be demolded by a straight pulling action, and the angle is different from that of the inclined insert core 31. Therefore, the first sliding member 6 and the second sliding member 7 are also provided in this embodiment.

[0040] The first sliding member 6 and the second sliding member 7 are fixedly connected to the upper mold 1. Thus, the first sliding member 6 and the second sliding member 7 move synchronously under the action of the upper mold 1. The first sliding member 6 is used to drive the inclined slider 3 to move, and the second sliding member 7 is used to drive the straight slider 4 to move. Thus, the inclined slider 3 and the straight slider 4 are respectively controlled by the first sliding member 6 and the second sliding member 7 fixedly arranged on the upper mold 2, and the first sliding member 6 and the second sliding member 7 are jointly controlled by the opening and closing actions of the upper mold 2. The opening and closing actions are converted into the actions of the inclined slider 3 and the straight slider 4, so that the mold realizes the extraction or insertion of the core during the demolding and closing processes, and the inclined slider 3 and the straight slider 4 move synchronously.

[0041] An inclined hole 33 for passing through the first sliding member 6 is provided on the inclined slider 3. The end faces of the first sliding member 6 and the inclined hole 33 close to or away from the cavity 5 are inclined downward. The spacing of the inclined end face of the inclined hole 33 is greater than the spacing of the inclined end face of the first sliding member 6.

[0042] The second sliding member 7 is provided with a T-shaped card slot 71. The end faces of the T-shaped card slot 71 facing the cavity 5 are all inclined downward. The straight slider 4 is provided with a T-shaped part 42 that is slidably matched with the T-shaped card slot 71. The T-shaped part 42 is fitted and clamped in the T-shaped card slot without clearance and can only slide along its inclined surface. When the second sliding member 7 is controlled by the upper mold 1 to move upward, the inclined surface of the T-shaped card slot 71 squeezes the T-shaped part, and the T-shaped part moves in the direction away from the cavity 5 along the inclined surface, realizing the action of pulling out the straight slider 4; similarly, when the second sliding member 7 is controlled by the upper mold 1 to move downward, the T-shaped part moves in the direction close to the cavity 5 along the inclined surface, realizing the action of inserting the straight slider 4 inward.

[0043] Thus, the straight slider 4 moves a longer distance than the inclined slider 3. After the straight slider 4 moves and is pulled out during demolding, the inclined slider 3 and the straight slider 4 can then be pulled out of the injection molded part together, avoiding damage to the injection molded part when the inclined slider 3 drives the straight slider 4 to move obliquely downward. And when closing the mold, the inclined slider 3 and the straight slider 4 are inserted together. After the inclined slider 3 reaches the position, the straight slider 4 can still move a certain distance to insert into the cavity 5, realizing the non-interfering actions of the inclined slider 3 and the straight slider 4, and the overall control is smooth.

[0044] The inclined surface of the T-shaped card slot 71 is parallel to the inclined end surface of the first sliding member 6, and the inclined angles between the inclined surface of the T-shaped card slot 71 and the inclined end surface of the first sliding member 6 and the horizontal plane are the same. When the inclined slider 3 and the straight slider 4 move synchronously, the upper die 1 is actuated to control the same displacement distance of the inclined slider 3 and the straight slider 4, ensuring synchronous movement.

[0045] Furthermore, a buffer structure is provided between the inclined slider 3 and the straight slider 4. The buffer structure includes connectors 20 on both sides of the straight slider 4. The connectors 20 are snap-fitted on the inclined slider 3. A V-shaped member 22 is provided between each connector 20 and the straight slider 4. The V-shaped member 22 is always pressed against the left and right side surfaces of the straight slider 4 under the action of a spring. The V-shaped member 22 and the spring are inserted through the straight slider 4 to prevent it from shaking left and right. After the straight slider 4 moves a certain distance relative to the inclined slider 3, the V-shaped member 22 is snap-fitted into the V-shaped groove 23 to achieve synchronous movement of the straight slider 4 and the inclined slider 3. Only after the inclined slider 3 reaches its position during the final mold closing, the second sliding member 7 continues to move downward to push the straight slider 4. At this time, the force exerted on the straight slider 4 by the second sliding member 7 in the movement direction is greater than the force exerted on the straight slider 4 by the spring extrusion of the V-shaped member 22 in the movement direction, causing the V-shaped member 22 to leave the V-shaped groove 23 and continue to extend. Thus, the buffer structure ensures that the straight slider 4 and the inclined slider 3 can be synchronously linked and can also move independently.

[0046] This embodiment further includes an upper fixing seat 15, a top plate 16, and a base 18. The upper fixing seat 15, the top plate 16, the upper die 1, the lower die 2, the bottom plate 17, and the base 18 are arranged in sequence from top to bottom. The bottom plate 17 and the base 18 are supported and fixed circumferentially by partitions and support columns, and a space is formed inside for arranging an ejection structure. The top plate 16 is used to ensure the stability between the upper die 1 and the upper fixing seat 15, reduce vibration and deformation caused by mold movement, and improve the accuracy during the production process. A push rod is provided below the base 18. A guide post 19 is disposed through between the upper fixing seat 15 and the bottom plate 17. The guide post 19 is slidably connected to the upper fixing seat 15, the top plate 16, the upper die 1, the lower die 2, and the bottom plate 17 through guide sleeves. While positioning each part of the mold, it can move along the direction of the guide post 19 to achieve the actions of demolding and mold closing. The lower die 2 and the bottom plate 17 are positioned by positioning columns and positioning sleeves to ensure accurate positioning and installation of the lower die 2, so as to ensure that the subsequent push rod can push the injection molded part more evenly. The upper die 1 and the lower die 2 are connected and closed by setting nylon hooks, so that only when the mold opening force is greater than the expansion force of the nylon hooks can the upper die 1 and the lower die 2 be separated.

[0047] The ejection structure includes an ejector plate base 8 and an ejector plate 9 disposed between the bottom plate 17 and the base 18. In this embodiment, it is a submarine gate, and the injection runner flows through the insert 21. Accordingly, a product ejector rod 12 and a runner ejector rod 13 are provided on the ejector plate 9. Both the product ejector rod 12 and the runner ejector rod 13 pass through the lower insert and are evenly distributed below the injection molded part and the injection runner, so that the ejection thrust is evenly distributed in the circumferential direction of the injection molded part, preventing the injection molded part from deforming due to uneven force during demolding. Moreover, the product ejector rod 12 and the runner ejector rod 13 serve as parts of the mold cavity 5 or the runner and are used to assist injection molding.

[0048] The ejector plate base 8 is disposed below the ejector plate 9 and is used to push the product ejector rod 12 and the runner ejector rod 13. When the ejector plate base 8 is pushed by a push rod, the ejector plate base 8 pushes the ejector plate 9 to drive the product ejector rod 12 and the runner ejector rod 13 to move upward, ejecting the injection molded part and the injection runner to achieve demolding. After demolding, the external push rod retracts. A reset member 14 is provided between the ejector plate 9 and the bottom plate 17. The reset member 14 can be a spring, and both ends of the spring are respectively abutted against the countersunk heads on the ejector plate 9 and the bottom plate 17. The product ejector rod 12 and the runner ejector rod 13 are reset under the action of the reset member 14.

[0049] Water channels 24 for cooling the runner and the mold cavity 5 are provided through both the upper mold 1 and the lower mold 2. By providing the water channels, it can be ensured that during the injection molding process, the injection runner and the injection mold cavity 5 can be cooled by water flow, accelerating the cooling and molding of the injection molded part and ensuring the quality of the injection molded product.
