Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a product demolding mechanism. Background Technology

[0002] Molds are specialized tools used in industrial production for mass manufacturing of products. Through specific shapes and structures, they use external forces to deform or shape raw materials, thereby obtaining parts or products with certain shapes, sizes and precision. They are widely used in many fields such as automobiles, electronics, home appliances, and medical devices, and are key to achieving efficient and standardized production.

[0003] Chinese patent CN220904012U discloses a product demolding mechanism applied to injection molds. It includes a fixed mold and a movable mold adapted to its side. The fixed mold and movable mold cooperate to form an injection cavity. A demolding mechanism for demolding the injection-molded product is provided within the movable mold. The demolding mechanism includes a push plate slidably disposed on the side of the movable mold. The push plate has a through groove adapted to the upper core of the movable mold. Four rectangularly distributed ejector pins are provided on the side surface of the push plate, with the other end of each ejector pin penetrating into the movable mold and fixing a panel thereon. The demolding mechanism also includes a driving component for moving the push plate. This solves the problem of manually demolding products that stick or jam, which increases labor intensity and reduces demolding efficiency.

[0004] Existing related technologies often have the following drawbacks: In the actual use of injection molds, release agent is often applied to the mold plate surface in advance using a brush. However, the brush application efficiency is low and cannot meet the need for rapid application of release agent to the mold plate surface.

[0005] Therefore, this utility model provides a product demolding mechanism. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of quickly applying release agent to the mold plate surface, and to propose a product demolding mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a product demolding mechanism, comprising a lower mold and an upper mold, wherein a mold cavity is formed on the upper surface of the lower mold, a mold plate is fixedly connected to the lower surface of the upper mold, and an applicator is provided on the side wall of the upper mold. The applicator includes a connecting strip fixedly connected to the side wall of the upper mold, a slide bar slidably connected to the lower side of the connecting strip, a rotating shaft rotatably connected inside the slide bar, and a sponge tube glued to the side wall of the rotating shaft.

[0008] The effect achieved by the above components is that the slide bar drives the rotating shaft and the outer sponge cylinder to move synchronously, and the sponge cylinder rolls on the surface of the mold plate, so that the release agent can be evenly coated on the surface of the mold plate.

[0009] Preferably, a stop is fixedly connected to the end side of the slide bar.

[0010] The effect achieved by the above components is that the stop block can prevent the slider from detaching from the connecting bar when it slides.

[0015] Preferably, a piston plate is slidably connected inside the storage box.

[0016] The effect achieved by the above components is that the piston plate slides along the inner wall of the storage box, which can lift the residual release agent at the bottom of the storage box, thus improving the subsequent dipping effect of the release agent.

[0017] Preferably, the storage box has an internal threaded connection to a drive rod, and the drive rod is internally rotatably connected to the piston plate.

[0018] The effect achieved by the above components is: rotating the drive rod on the storage box causes the drive rod to push the internal piston plate to slide along the inner wall of the storage box.

[0020] The effect achieved by the above-mentioned components is that by setting up auxiliary structures, it is convenient to flexibly adjust the gap between the injection molded product and the mold cavity, thereby further improving the demolding efficiency of the injection molded product.

[0021] Preferably, the lower mold is internally threaded with a screw, and the screw is internally rotatably connected to the push plate.

[0022] The effect achieved by the above components is that the screw facilitates the driving of the push plate.

[0023] Preferably, a retaining ring is fixedly connected to the screw on the side outside the lower mold.

[0024] The effect achieved by the above components is that the retaining ring is driven to a position that abuts against the side of the lower mold, at which point the upper mold and the lower mold can be closed.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a product demolding mechanism, including a lower mold 1 and an upper mold 2. The upper surface of the lower mold 1 is provided with a mold cavity 3, the lower surface of the upper mold 2 is fixedly connected with a mold plate 4, the side wall of the upper mold 2 is provided with a coating device 5, and the inner side of the lower mold 1 is provided with an auxiliary structure 6.

[0032] The following section will describe in detail the specific setup and function of its coating device 5 and auxiliary structure 6.

[0033] Reference Figures 1-4 As shown, in this embodiment: the coating device 5 includes a connecting strip 501 fixedly connected to the side wall of the upper mold 2, a slide bar 502 slidably connected to the lower side of the connecting strip 501, a rotating shaft 503 rotatably connected inside the slide bar 502, and a sponge tube 504 glued to the side wall of the rotating shaft 503. The slide bar 502 drives the rotating shaft 503 and the outer sponge tube 504 to move synchronously, and the sponge tube 504 rolls on the surface of the mold plate 4, thus uniformly coating the mold release agent onto the surface of the mold plate 4. A stop block 510 is fixedly connected to the end side of the slide bar 502. The stop block 510 can prevent the slide bar 502 from detaching from the connecting strip 501 when sliding. A handle 511 is fixedly connected to the other side of the slide bar 502. By holding the handle 511 on the end side of the slide bar 502, the slide bar 502 is pushed to slide along the connecting strip 501. A fixing rod 506 is fixedly connected to the side wall of the lower mold 1. A sleeve 505 is slidably connected to the lower side of the fixing rod 506, and a storage box 507 is fixedly connected to the lower end of the sleeve 505. The sponge cylinder 504 is dipped in the release agent stored in the storage box 507, ensuring that the release agent can penetrate into the sponge. A piston plate 508 is slidably connected inside the storage box 507. The piston plate 508 slides along the inner wall of the storage box 507, which can lift the release agent remaining at the bottom wall of the storage box 507, improving the subsequent dipping effect of the release agent. A drive rod 509 is threadedly connected inside the storage box 507, and the drive rod 509 and the piston plate 508 are internally rotatably connected. Rotating the drive rod 509 on the storage box 507 causes the drive rod 509 to push the internal piston plate 508 to slide along the inner wall of the storage box 507.

[0034] Reference Figure 1 and Figure 5 As shown, specifically, the auxiliary structure 6 includes four limiting strips 63 that are slidably connected in pairs inside the lower mold 1. Two of the limiting strips 63 are fixedly connected to a push plate 61 at one end inside the mold cavity 3 of the lower mold 1. By setting the auxiliary structure 6, the gap between the injection molded product and the mold cavity 3 can be flexibly adjusted, further improving the demolding efficiency of the injection molded product. A screw 62 is threadedly connected inside the lower mold 1, and the screw 62 is rotatably connected to the push plate 61. The screw 62 facilitates the driving of the push plate 61. A retaining ring 65 is fixedly connected to one side of the screw 62 on the outside of the lower mold 1. The upper mold 2 and the lower mold 1 can be closed when the retaining ring 65 is driven to a position against the side of the lower mold 1. A rotating block 64 is fixedly connected to the end of the screw 62. Rotating the rotating block 64 will cause the screw 62 to twist.

[0035] Working principle: Before injection molding, a release agent needs to be applied to the surface of the mold plate 4. First, the sponge cylinder 504 is moved to the position above the storage box 507. At this time, the sleeve 505 on the surface of the sliding fixing rod 506 lifts the storage box 507, allowing the sponge cylinder 504 to be dipped in the release agent stored in the storage box 507, ensuring that the release agent can penetrate into the sponge. Then, the handle 511 on the end of the slider 502 is held, and the slider 502 is pushed to slide along the connecting strip 501. At this time, the slider 502 drives the rotating shaft 503 and the outer sponge cylinder 504 to move synchronously. The sponge cylinder 504 rolls on the surface of the mold plate 4, thus releasing the release agent. The mold release agent is evenly coated on the surface of the mold plate 4. The stop block 510 can prevent the slide bar 502 from detaching from the connecting bar 501 when sliding, ensuring the stability of the coating process. The operator can rotate the drive rod 509 on the storage box 507 to push the internal piston plate 508 to slide along the inner wall of the storage box 507. This can lift the residual mold release agent at the bottom wall of the storage box 507, improving the subsequent coating effect of the mold release agent. By setting the coating device 5, the mold release agent can be quickly and evenly coated, reducing the inefficiency of manual brush coating and improving the demolding efficiency of injection molded products to a certain extent.

[0036] Before injection molding the product, rotate the rotating block 64. The rotating block 64 will drive the screw 62 to twist until the retaining ring 65 is driven to a position against the side of the lower mold 1. At this time, the upper mold 2 and the lower mold 1 can be closed. After injection molding is completed, after the mold is opened, rotate the rotating block 64 in the opposite direction. At this time, the push plate 61 can be moved and reset. At this time, there will be a certain gap between the injection molded product and the inner side of the mold cavity 3, which reduces the adhesion area between the injection molded product and the mold cavity 3, thereby further improving the demolding efficiency of the injection molded product. By setting the auxiliary structure 6, it is convenient to flexibly adjust the gap between the injection molded product and the mold cavity 3, further improving the demolding efficiency of the injection molded product.
