Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to an anti-flying nozzle half-cover injection mold. Background Technology

[0002] An anti-flip nozzle is used in conjunction with a hair dryer to prevent hair from flying up during blow-drying. It mainly consists of an air duct and a plastic part with a certain arc shape. For example, Chinese patent CN220832220U discloses an anti-flip nozzle, which is formed by two thin-walled half-caps fastened together. When using normal injection molding, the sprue is attached to the product, and separation can easily damage the product. If a submersible injection method is used, a waist-shaped hole needs to be opened on the slider for the ejector rod to eject the sprue. The sprue can easily leak along the waist-shaped hole to the bottom of the slider, causing the slider to jam and damaging the mold. Therefore, there is an urgent need for an injection mold specifically designed for molding the anti-flip nozzle half-caps. Utility Model Content

[0003] The purpose of this invention is to overcome one or more shortcomings in the prior art and to provide an anti-flying nozzle half-cover injection mold.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is an anti-flying nozzle half-cover injection mold, comprising:

[0005] The mold core has a cavity inside which a half-cover for forming an anti-warping nozzle is formed. The mold core is composed of an openable lower mold core and an upper mold core.

[0006] A slider is slidably mounted on the lower mold core. The upper surface of the slider is provided with a runner and a submerged injection nozzle. The submerged injection nozzle is located at the end of the runner near the cavity and penetrates the side wall of the slider. The submerged injection nozzle connects the runner and the cavity.

[0007] The slider is equipped with a long strip-shaped top block that can slide up and down. The outer wall of the top block is dynamically sealed to the slider. When the mold is closed, the upper end face of the top block is flush with the upper end face of the slider. A part of the runner is located on the upper end face of the top block. When the mold is opened, the slider slides horizontally relative to the lower mold core, so that the sprue in the runner and the submerged injection gate separates from the anti-warping nozzle half cover in the cavity. At the same time, the top block moves upward relative to the slider, pushing the sprue upward.

[0008] Preferably, the slider is connected to a slider seat for driving the slider to slide horizontally. The slider seat is located outside the lower mold core. When the mold is closed, the side wall of the slider seat is in contact with the side wall of the lower mold core. When the mold is opened, the side wall of the slider seat is spaced apart from the side wall of the lower mold core.

[0009] More preferably, an inclined guide rod is axially slidably inserted on the slider seat, and the upper end of the inclined guide rod is connected to the upper template on which the upper mold core is set.

[0010] Preferably, the lower end of the top block is provided with a push rod for driving the top block to move up and down. The upper end of the push rod is horizontally slidably connected to the lower end of the top block. When the push rod drives the top block to move upward, the top block adapts to the horizontal sliding of the slider relative to the lower mold core by sliding relative to the push rod.

[0011] More preferably, the lower end of the top block is provided with a downward through T-shaped groove, and the upper end of the top rod is provided with a T-shaped boss that matches the T-shaped groove. The T-shaped boss can be horizontally slidably embedded in the T-shaped groove.

[0012] More preferably, the lower end of the push rod is connected to the drive plate, the drive plate is movably disposed above the lower template, and the lower mold core is disposed on the lower template.

[0013] Preferably, the anti-warping nozzle half-cover injection mold further includes an injection rod, which extends vertically and the lower end of the injection rod passes through the upper mold core and is aligned with the flow channel on the upper surface of the top block.

[0014] More preferably, the upper end face of the top block is also provided with a downwardly extending buffer blind hole, which is located in the middle of the flow channel. When the mold is closed, the buffer blind hole is coaxial with the injection rod.

[0015] More preferably, the bottom wall of the flow channel is provided with a downwardly extending easy-release blind hole, the easy-release blind hole is located on the slider, and the easy-release blind hole is used to form an easy-release column on the material head to facilitate the material head to detach from the top block.

[0016] More preferably, the injection rod, the upper mold core, and the upper template on which the upper mold core is mounted move synchronously.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] This utility model provides an anti-warping nozzle half-cap injection mold, including a mold core consisting of an openable lower mold core and an upper mold core, which form the cavity for molding the anti-warping nozzle half-cap; a slider that can be horizontally slidably disposed on the lower mold core; a runner and a submerged injection gate on the upper surface of the slider; the submerged injection gate is located at the end of the runner near the cavity and penetrates the side wall of the slider, and the submerged injection gate connects the runner and the cavity; by means of a long strip-shaped top block that can slide up and down on the slider and is dynamically sealed, when the mold is closed, the upper end face of the top block is flush with the upper end face of the slider, so that part of the runner is located on the upper end face of the top block; when the mold is opened, the horizontal sliding of the slider relative to the lower mold core can be used to separate the sprue in the runner and the submerged injection gate from the anti-warping nozzle half-cap in the cavity; at the same time, the upward movement of the top block relative to the slider can be used to push the sprue upward, which can realize submerged injection, prevent damage to the product during separation, and prevent the sprue from leaking to the bottom of the slider, thereby extending the service life of the mold.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0033] like Figures 3 to 8 As shown, the anti-warping nozzle half-cap injection mold provided by this utility model includes: a mold core, a slider 30, and an ejector block 40. The mold core has a cavity for forming the anti-warping nozzle half-cap 1, and is composed of an openable lower mold core 10 and an upper mold core 20. The slider 30 is horizontally slidably mounted on the lower mold core 10. The upper surface of the slider 30 has a runner 31 and a submerged injection nozzle 32. The submerged injection nozzle 32 is located at the end of the runner 31 near the cavity and penetrates the side wall of the slider 30. The submerged injection nozzle 32 connects the runner 31 and the cavity. The cavity; the top block 40 is long and can slide up and down through the slider 30. The outer wall of the top block 40 is dynamically sealed to the slider 30. When the mold is closed, the upper end face of the top block 40 is flush with the upper end face of the slider 30. A part of the runner 31 is located on the upper end face of the top block 40. When the mold is opened, the slider 30 slides horizontally relative to the lower mold core 10, so that the sprue 2 in the runner 31 and the injection nozzle 32 is separated from the anti-warping nozzle half cover 1 in the cavity. At the same time, the top block 40 moves upward relative to the slider 30, pushing the sprue 2 upward.

[0034] The advantage of this design is that it can utilize the horizontal sliding of the slider relative to the lower mold core to separate the sprue head in the runner and submerged injection gate from the anti-warping nozzle half-cap in the cavity. It can also utilize the upward movement of the ejector block relative to the slider to push the sprue head upward. This not only achieves submerged injection and prevents damage to the product during separation, but also prevents the sprue from leaking to the bottom of the slider through the dynamic sealing connection between the ejector block and the slider, thereby extending the service life of the mold.

[0035] In this embodiment, a slider seat 50 is connected to the slider 30 for driving the slider 30 to slide horizontally. The slider seat 50 is located outside the lower mold core 10. When the mold is closed, the side wall of the slider seat 50 is in contact with the side wall of the lower mold core 10. When the mold is opened, the side wall of the slider seat 50 is spaced apart from the side wall of the lower mold core 10. Furthermore, an inclined guide rod 51 is axially slidably provided on the slider seat 50. The upper end of the inclined guide rod 51 is connected to the upper template on which the upper mold core 20 is provided.

[0036] To avoid interference between the vertical movement of the top block 40 and the horizontal movement of the slider 30, in this embodiment, the lower end of the top block 40 is provided with a push rod 41 for driving the top block 40 to move vertically. The upper end of the push rod 41 is horizontally slidably connected to the lower end of the top block 40. When the push rod 41 drives the top block 40 to move upward, the top block 40 adapts to the horizontal sliding of the slider 30 relative to the lower mold core 10 by sliding relative to the push rod 41. Specifically, the lower end of the top block 40 is provided with a T-shaped groove 42. The T-shaped groove 42 extends parallel to the sliding direction of the slider 30 and penetrates the side wall of the opposite side of the top block 40. The T-shaped groove 42 also extends downward and penetrates the bottom wall of the top block 40. The upper end of the push rod 41 is provided with a T-shaped boss 43 that matches the T-shaped groove 42. The T-shaped boss 43 is horizontally slidably embedded in the T-shaped groove 41.

[0037] To facilitate the driving of the ejector pin 41, in this embodiment, the lower end of the ejector pin 41 is connected to the drive plate 61. The drive plate 61 is movably positioned above the lower mold plate 62, and the lower mold core 10 is positioned on the lower mold plate 62.

[0038] In this embodiment, the anti-warping nozzle half-cover injection mold also includes an injection rod 70, which extends vertically. The lower end of the injection rod 70 passes through the upper mold core 20 and is aligned with the flow channel 31 on the upper surface of the top block 40. To reduce the impact force of the glue, a downwardly extending buffer blind hole 44 is further provided on the upper surface of the top block 40. The buffer blind hole 44 is located in the middle of the flow channel 31. When the mold is closed, the buffer blind hole 44 is coaxial with the injection rod 70. To facilitate the sprue from the top block 40, a downwardly extending easy-release blind hole 33 is further provided on the bottom wall of the flow channel 31. The easy-release blind hole 33 is located on the slider 30. The easy-release blind hole 33 is used to form an easy-release pillar 3 on the sprue 2 to facilitate the sprue 2 from the top block 40.

[0039] In this embodiment, the injection rod 70, the upper mold core 20, and the upper template on which the upper mold core 20 is set move synchronously.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
