Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a vacuum forming demolding and ejection structure that prevents the film of an IML product from falling over. Background Technology

[0002] IML products have an inverted structure. IML film vacuum forming uses forced demolding. The film at the inverted position is stretched, making demolding difficult, causing the film to deform and the product appearance to fail to meet customer requirements. Utility Model Content

[0003] To address the shortcomings of existing technologies, a vacuum forming demolding ejection structure is provided to prevent the IML product film from falling over during vacuum forming. The structure includes an ejection mechanism mounted on a high-pressure vacuum forming mold. An IML product structure is mounted on the high-pressure vacuum forming mold. A pressure block presses the IML film onto the ejection mechanism, and the IML film and the IML product structure are closely connected.

[0004] Furthermore, it also includes a parting surface structure, which is disposed on the high-pressure vacuum forming mold.

[0005] Furthermore, the parting surface structure is connected to the IML product structure.

[0006] Furthermore, the ejection mechanism includes a spring and a spring block, with the bottom of the spring fixedly mounted on the high-pressure vacuum forming mold and the top of the spring connected to the spring block.

[0007] Furthermore, the pressure block presses the IML diaphragm onto the spring block of the ejection mechanism.

[0008] The beneficial effects of this invention are as follows: The ejection structure of this invention enables rapid separation of the diaphragm from the mold, reducing tensile resistance, solving the problem of diaphragm deformation, and ensuring that the appearance of the IML product structure meets customer requirements. This invention also optimizes the parting surface structure next to the high-pressure vacuum forming mold, increasing the strength of the adjacent diaphragm and solving the diaphragm deformation problem, thus ensuring that the product appearance meets customer requirements.

[0021] A thermoforming ejection structure to prevent the film from falling out of the IML product, such as Figures 1-8 As shown, it includes an ejection mechanism 1, which is mounted on a high-pressure vacuum forming mold 4. An IML product structure 5 is mounted on the high-pressure vacuum forming mold 4. A pressure block 2 presses an IML film 3 onto the ejection mechanism 1, and the IML film 3 is bonded and connected to the IML product structure 5.

[0022] It also includes a parting surface structure 6, which is disposed on the high-pressure vacuum forming mold 4.

[0023] Parting surface structure 6 is connected to IML product structure 5. After optimization of the parting surface structure, as follows: Figures 9-10 As shown, the strength of the diaphragm in region 6 of the parting surface structure with different heights is increased to prevent demolding deformation, thus solving the problem of weak diaphragm strength in the planar structure before the parting surface structure optimization.

[0024] The ejection mechanism 1 includes a spring 11 and a spring block 12. The bottom of the spring 11 is fixedly mounted on the high-pressure vacuum forming mold 4, and the top of the spring 11 is connected to the spring block 12.

[0025] The pressure block 2 presses the IML diaphragm 3 onto the spring block 12 of the ejection mechanism 1.

[0026] The structure of the IML product consists of three sides covered with an IML film, with two sides being inverted. The film is vacuum-formed in a high-pressure vacuum forming mold. After forming, the inverted parts cannot be easily demolded, causing the film to be stretched and deformed. To address this, the high-pressure vacuum forming mold is optimized with an improved parting surface structure 6 to increase the strength of the adjacent film; an ejector structure 1 is added. During the vacuum forming and mold closing process, the pressure block 2 presses onto the IML film 3 and pushes the spring block 12 back into place. During the mold opening process after vacuum forming, the pressure block 2 quickly lifts up, and the spring block 12, under the action of the spring 11, ejects the IML film 3 first. The IML film 3 quickly separates from the mold, reducing tensile resistance, solving the deformation problem of the IML film 3, and ensuring that the appearance of the IML product structure 5 meets customer requirements.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
