Description

Technical Field

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

[0002] The demolding mechanism for plastic molds is one of the core functional components of plastic injection molding molds. It refers to a mechanical structure system that, after injection molding and during the mold opening stage, uses mechanical force, pneumatic pressure, hydraulic pressure, or electric drive to smoothly and completely remove the cooled and solidified plastic product from the mold cavity or core in a specific motion manner, ultimately realizing the removal of the product and the continuous production cycle of the mold. The demolding mechanism for plastic molds is used in scenarios where, after the plastic product is injection molded, the cooled and solidified plastic product is smoothly removed from the mold cavity or core during the mold opening stage, ensuring the integrity and undamaged nature of the product and enabling continuous production.

[0003] When workers need to demold material from a plastic mold, they inject the material into the mold so that the demolding mechanism can demold the material. However, existing demolding mechanisms usually use a single ejection mechanism to demold the material, which can cause scratches on the surface of the material and lead to a decrease in the quality of the material.

[0016] The following section will explain the specific setup and function of the demolding device 3 and the ejection device 4.

[0017] In this embodiment: the demolding device 3 includes a main platform 37, which is placed on the lower surface of the second mold 2 and located below the first mold 1. A guide groove 36 is provided on the surface of the main platform 37. A slider 34 is fixedly connected to the lower surface of the second mold 2 and is slidably connected to the inside of the guide groove 36. A drive motor 31 is fixedly connected to the surface of the main platform 37 and is located below the second mold 2. A connecting block 35 is placed on the lower surface of the main platform 37, and an adjusting strip 33 is rotatably connected between the connecting block 35 and the slider 34. The adjusting strip 33 is located below the second mold 2. An adjusting component is provided on the lower surface of the main platform 37.

[0018] Specifically, the adjustment component includes a transmission rod 32, which is fixedly connected to the drive end of the drive motor 31, rotatably connected to the inside of the main platform 37, and threadedly connected to the inside of the connecting block 35. The transmission rod 32 can cooperate with the connecting block 35 to adjust the two connecting blocks 35 to move closer to each other. The transmission rod 32 is a bidirectional threaded rod.

[0019] Specifically, the surface of the main platform 37 is fixedly connected to a guide bar 38, and the two second molds 2 are slidably connected to the surface of the guide bar 38.

[0020] In this embodiment, the guide bar 38 can cooperate with the main platform 37 to guide the second mold 2 to slide.

[0021] In this embodiment: the surface of the main platform 37 is provided with an ejection device 4, which includes an electric rod 42. The electric rod 42 is fixedly connected to the interior of the main platform 37. The electric rod 42 is located below the second mold 2. The electric rod 42 can cooperate with the main platform 37 to achieve the purpose of supporting the electric rod 42.

[0022] Specifically, a column 41 is fixedly connected to the surface of the main platform 37, two second molds 2 are fitted on the surface of the column 41, and the drive end of the electric rod 42 is inside the column 41.

[0023] In this embodiment, the column 41 can cooperate with the main platform 37 to achieve the purpose of supporting the column 41.

[0024] Specifically, a storage slot 43 is provided at the top of the column 41. The storage slot 43 is located above the electric rod 42. The storage slot 43 can cooperate with the column 41 to achieve the purpose of storing the push plate 44.

[0025] Specifically, the drive end of the electric rod 42 is fixedly connected to a push plate 44, and the push plate 44 is slidably connected to the inside of the storage slot 43.

[0027] Working principle: By setting up the demolding device 3, when the worker needs to protect the surface of the material, the worker starts the drive motor 31, which drives the conveyor rod 32. The conveyor rod 32 adjusts the two connecting blocks 35 to move closer together. The connecting blocks 35 push the adjusting strip 33, which pushes the slider 34. The two sliders 34 drive the two second molds 2 to move away from each other, and the material detaches from the second mold 2. The material adheres to the surface of the column 41, and the ejection device 4 is activated to eject the material. By setting up the demolding device 3, the surface of the material can be effectively protected, preventing the surface of the material from being exposed. The absence of scratches improves material quality. Furthermore, by installing the ejector device 4, when the worker needs to eject the material, the electric rod 42 is activated, pulling the push plate 44. Guided by the receiving groove 43, the push plate 44 detaches from the material. Then, the electric rod 42 is controlled to push the push plate 44 upwards, lifting the material and detaching it from the column 41. The worker can then remove the material. The ejector device 4 effectively ejects the material, avoiding inconvenience for workers when unloading, thus improving work efficiency.
