Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for forming a display shell. Background Technology

[0002] Currently, molds are tools used to create shaped objects. These tools are composed of various different parts. Molds mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are known as the "mother of industry". At the same time, injection molds are tools for producing plastic products, and also tools for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used for mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidification, obtaining the shaped product.

[0003] Furthermore, the product structure determines the structure of the injection mold. For products that are concave or convex, the mold core will have an undercut structure, and the amount of undercut determines the demolding structure of the mold. The molding mechanism is selected according to the amount of undercut of the product. However, the existing display shell molding mold design is not good. Its molding slider is centrally set on the lower mold, which makes the overall structure of the lower mold complicated, the production cost is high, and the slider is prone to damage to the product when it detaches from the injection molded product, affecting the product injection effect, failing to meet the user's needs, and having poor usability and limited application range.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a display shell molding mold. Through the design of each component, it facilitates the ingenious arrangement of the overall mold structure. In conjunction with the setting of the first release coating, it reduces the contact friction between the corresponding molding slider and the injection molded product, thereby avoiding damage when the injection molded product separates from the corresponding slider, ensuring the molding quality of the injection molded product, and meeting the user's needs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A display casing molding die includes an upper die, a lower die, a first molding mechanism, and a second molding mechanism; wherein:

[0008] The upper mold has a cavity. The first molding mechanism is disposed on one side of the upper mold and located beside the cavity. The first molding mechanism includes a first molding part and a first displacement device for driving the first molding part to move. The first displacement device is disposed on the outside of the upper mold. The outside of the upper mold has a clearance opening that communicates with the cavity. The output end of the first displacement device is connected to the first molding part through the clearance opening. The inner end of the first molding part is provided with a first molding surface.

[0009] The lower mold has a core, and the second forming mechanism is located on the other side of the lower mold away from the first forming mechanism and next to the core.

[0010] Furthermore, a first release coating is provided on both the first molding surface and the second molding surface, and an injection mold cavity is formed between the core, the cavity, the first molding surface and the second molding surface.

[0011] As a preferred embodiment, the cavity is provided with a second release coating.

[0042] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0043] A display casing molding die includes an upper mold 10, a lower mold 20, a first molding mechanism 12, and a second molding mechanism 22; wherein:

[0044] The upper mold 10 has a cavity 11. The first molding mechanism 12 is disposed on one side of the upper mold 10 and located beside the cavity 11. The first molding mechanism 12 includes a first molding part 121 and a first displacement device 122 for driving the first molding part to move. The first displacement device 122 is disposed on the outside of the upper mold 10. The outside of the upper mold 10 is provided with a clearance opening 111 communicating with the cavity. The output end of the first displacement device 122 is connected to the first molding part 121 through the clearance opening 111. The inner end of the first molding part 121 is provided with a first molding surface (not shown in the figure).

[0045] The lower mold 20 has a core 21. The second molding mechanism 22 is disposed on the other side of the lower mold 20 away from the first molding mechanism 12 and located beside the core 21. The second molding mechanism 22 includes a second molding part 221, a mounting base 222 and a second displacement device 223 for driving the second molding part. The mounting base 222 is disposed on the outer side of the lower mold 20. The second displacement device 223 is driven and connected to the second molding part 221 and disposed on the mounting base 222. The inner end of the second molding part 221 is provided with a second molding surface 224. The upper mold 10 is provided with a relief groove 112 corresponding to the second molding part.

[0046] Furthermore, a first release coating 225 is provided on both the first molding surface and the second molding surface 224, and an injection mold cavity 101 is formed between the core 21, the cavity 11, the first molding surface and the second molding surface 224;

[0047] When the upper mold closes to the lower mold, the first displacement device and the second displacement device control the inward displacement of the first molding part and the second molding part, respectively. After the product is injected, the first displacement device controls the first molding part to move away from the injected product, and then the second displacement device controls the second molding part to move away from the injected product. Finally, the upper mold and the lower mold open and the workpiece is removed. In this way, through the design of each component, the first and second molding mechanisms are set at the upper mold and the lower mold, respectively, eliminating the centralized arrangement of the molding mechanism. This is conducive to the ingenious arrangement of the overall mold structure. With the setting of the first release coating, the contact friction between the corresponding molding slider and the injected product is reduced, thereby avoiding damage when the injected product separates from the corresponding slider. Furthermore, the sequential separation of the first molding part and the second molding part avoids the pulling on both sides when the first and second molding parts separate from the injected product at the same time, thus avoiding mutual interference and damage to the injected product. This ensures the molding quality of the injected product. The structural design is ingenious and reasonable, meets the user's needs, has good usability, and a wide range of applications.

[0048] Furthermore, a second release coating 113 is provided on the cavity 11. Both the first release coating 113 and the second release coating 225 are nano-release agent coatings. Thus, the provision of the second release coating reduces the contact friction between the upper mold and the injection molded product when the upper mold separates, avoids damage to the injection molded product when it separates from the cavity, ensures the appearance of the injection molded product, and has strong practicality.

[0049] Furthermore, the cavity 11 is provided with a stop portion 114 for stopping and positioning the displacement distance of the first forming part. The clearance opening 111 is located on the side of the stop portion 114. The inner end of the stop portion 114 is provided with a stop surface 115. When the first forming part 121 moves outward, the outer end of the first forming part 121 contacts the stop surface 115.

[0050] The output end of the first displacement device 122 is provided with a connecting part 123. The connecting part 123 extends into the clearance opening 111 and connects to the first forming part 121. There are two of each of the first displacement device 122 and the connecting part 123, which are arranged at intervals along the length direction of the first forming part. Correspondingly, there are two clearance openings 111. The stop part 114 is located between the two clearance openings 111. In this way, the setting of the stop part is beneficial to the displacement and positioning of the first forming part in the cavity, and ensures the stability of the first forming part in use.

[0051] Furthermore, the mounting base 222 is provided with a first slider 226 extending horizontally from the inside out, and the lower mold 20 is provided with a second slider 211 extending horizontally from the inside out. The first slider 226 is located outside the second slider 211. The second forming part 221 is provided with a sliding groove 227, which is adapted to the first slider 226 and the second slider 211. When the second forming part 221 is displaced, the sliding groove 227 moves on the first slider 226 and the second slider 211 respectively. Specifically, the second forming part 221 is provided with a positioning edge 228 for contacting and positioning with the core. The positioning edge 228 is located at the lower end of the second forming surface 224. Thus, the arrangement of the first slider and the second slider is beneficial to the displacement stability of the second forming part on the mounting base and the lower mold. At the same time, the arrangement of the positioning edge is beneficial to the displacement positioning between the second forming part and the core.

[0052] Preferably, the inner wall surface of the clearance opening 111 is provided with a first wear-resistant coating (not shown in the figure), and the inner wall of the slide groove 227 is provided with a second wear-resistant coating (not shown in the figure). Both the first and second wear-resistant coatings are made by spraying ceramic coatings. Thus, the first wear-resistant coating improves the wear resistance of the clearance opening, and the second wear-resistant coating improves the wear resistance of the slide groove, ensuring the stability of the second forming part in use.

[0053] The key design feature of this utility model lies in the fact that, through the design of each component, the first and second molding mechanisms are respectively set at the upper and lower molds, eliminating the centralized arrangement of the molding mechanisms. This facilitates the ingenious arrangement of the overall mold structure. Combined with the setting of the first release coating, the contact friction between the corresponding molding slider and the injection molded product is reduced, thereby avoiding damage when the injection molded product separates from the corresponding slider. The ingenious and reasonable structural design ensures the molding quality of the injection molded product, meets the user's needs, has excellent usability, and a wide range of applications.

[0054] Secondly, the second release coating is designed to reduce the contact friction between the upper mold and the injection molded product during separation, preventing damage to the injection molded product when it separates from the cavity, ensuring the appearance of the injection molded product, and making it highly practical. At the same time, the stop part is designed to facilitate the displacement and positioning of the first molding part in the cavity, ensuring the stability of the first molding part in use. Furthermore, the first wear-resistant coating improves the wear resistance of the clearance opening.

[0055] Furthermore, the arrangement of the first and second sliders facilitates the displacement stability of the second forming part on the mounting base and the lower mold. At the same time, the arrangement of the positioning edge facilitates the displacement positioning between the second forming part and the core. Additionally, the arrangement of the second wear-resistant coating improves the wear resistance of the groove and ensures the stability of the second forming part in use.

[0056] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
