Description

Technical Field

[0001] This utility model relates to the field of inner coating technology for box lids, specifically to an inner coating mold for manufacturing high and low temperature resistant, two-color transparent food storage box lids. Background Art

[0002] Food storage containers are not only convenient and practical, but they also allow for the organized storage of food. Plastic food storage containers should not be placed in microwaves or ovens, as high temperatures can cause the plastic to release harmful substances. Plastic food storage containers can be placed inside other food storage containers. Furthermore, tempered glass food storage containers may spontaneously shatter under extreme cold or heat; therefore, molds are required when manufacturing the lids.

[0003] In existing molds, the upper and lower molds are typically limited by a connecting plate during the casting and encapsulation process. This ensures that the distance the molds move is just right for removing the product. However, when dealing with upper and lower molds of different thicknesses, the gap between the molds increases, rendering the original limiting plate unsuitable and requiring replacement of the connecting plate. Furthermore, aligning the upper and lower molds necessitates repeated adjustments to the upper mold's position, which is quite cumbersome. Therefore, technological innovation and design optimization are needed to improve the inner encapsulation mold used for manufacturing high and low temperature resistant dual-color transparent food storage box lids. Utility Model Content

[0004] In existing upper and lower molds, during the pouring and encapsulation process, a connecting plate typically limits the movement of the upper and lower molds to ensure the product can be removed precisely within that distance. However, when dealing with upper and lower molds of varying thicknesses, the gap between the molds widens, rendering the original limiting plate unsuitable and necessitating replacement of the connecting plate. Furthermore, aligning the upper and lower molds requires repeated adjustments to the upper mold's position, which is cumbersome. To address these issues, this application provides an inner encapsulation material for manufacturing high and low temperature resistant, two-color transparent food storage container lids. The mold adjusts the position of the threaded post in the sliding hole by inserting the limiting block on the ring into the limiting groove of the corresponding thickness, and then passing the threaded post two through the ring and rotating it into the threaded hole two. This allows the upper and lower molds to move at a distance that is just right for opening the upper and lower templates and removing the product. This adapts to upper and lower templates of different thicknesses, making it highly versatile. At the same time, by fixing protrusions around the upper mold and concave blocks around the lower mold, the protrusions are inserted into the concave blocks, which facilitates the limiting and alignment of the upper and lower molds. In addition, the setting of upper and lower magnetic blocks can improve the efficiency of alignment.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] Inner encapsulation molds for manufacturing high and low temperature resistant, two-color transparent food storage container lids include:

[0007] The lower mold has an upper mold at its top, a lower template at its top, an upper template at its bottom, and an injection port at its top that penetrates the upper template.

[0008] A connecting plate is located on the same side of the upper mold and the lower mold. The connecting plate is provided with an adjustment mechanism for adjusting the distance between the upper mold and the lower mold.

[0009] Alignment mechanism, located on the four side walls of the upper and lower molds, for aligning the upper and lower molds.

[0010] In one possible implementation, the upper mold and the lower mold are respectively provided with a threaded hole one and a threaded hole two, the connecting plate is provided with a sliding hole and an adjusting groove, the sliding hole is provided with a threaded post one, the adjusting groove is provided with a threaded post two, and the threaded post one can slide in the sliding hole.

[0011] In one possible implementation, the first threaded post can be threadedly connected to the first threaded hole, and the second threaded post can be threadedly connected to the second threaded hole. Rotating the first and second threaded posts can connect the upper and lower molds, which can improve the adhesion of the two colored adhesives and improve product quality.

[0012] In one possible implementation, the adjustment mechanism includes a ring fitted on the threaded post II, a limit block fixed on the ring, and a limit groove formed on the connecting plate. The limit block matches the limit groove. When it is necessary to connect upper and lower templates of different thicknesses, it is necessary to adjust the position of the threaded post II inside the adjustment groove. At this time, the limit block on the ring is inserted into the limit groove of the corresponding thickness, and then the threaded post II is passed through the ring and rotated into the threaded hole II, thereby completing the adjustment of the threaded post II. When the threaded post slips, it can also limit the connection plate, improving the stability of the connection plate.

[0013] In one possible implementation, the alignment mechanism includes protrusions fixed around the upper mold and concave blocks fixed around the lower mold. The protrusions and concave blocks are matched, and the protrusions are inserted into the concave blocks. The concave blocks can align the protrusions and also prevent the upper mold from sliding on the lower mold.

[0014] In one possible implementation, an upper magnetic block is fixed to the bottom of the protrusion and a lower magnetic block is fixed to the top of the concave block, further improving the convenience of alignment.

[0015] In one possible implementation, both the first and second threaded posts are fixed with circular baffles to facilitate the rotation of the first and second threaded posts, while also preventing the connecting plate from falling off the first and second threaded posts.

[0016] In one possible implementation, the magnetic poles of the upper and lower magnetic blocks facing each other are opposite, and the upper and lower magnetic blocks attract each other.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] 1. By inserting the limiting block on the ring into the limiting groove of the corresponding thickness, and then passing the threaded post two through the ring and rotating it into the threaded hole two, the position of the threaded post one in the sliding hole is adjusted so that the moving distance between the upper mold and the lower mold is just right to open the upper template and the lower template and take out the product. This adapts to upper and lower templates of different thicknesses and has high applicability.

[0019] 2. By fixing protrusions around the upper mold and concave blocks around the lower mold, the protrusions are inserted into the concave blocks, which facilitates the limiting and alignment of the upper and lower molds. At the same time, the setting of upper and lower magnetic blocks can improve the efficiency of alignment. Attached Figure Description

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] This embodiment describes the specific structure of the inner rubber-coating mold used to manufacture a high- and low-temperature resistant, two-color transparent food storage box lid. See details in the attached document. Figures 1-6 As shown, the inner encapsulation mold for manufacturing a high and low temperature resistant, two-color transparent food storage container lid includes:

[0029] The lower mold 1 has an upper mold 2 at its top and a lower template 8 at its top. The upper mold 2 has an upper template 10 at its bottom and an injection port 4 at its top, which penetrates the upper template 10.

[0030] The connecting plate 3 is located on the same side of the upper mold 2 and the lower mold 1. The connecting plate 3 is provided with an adjustment mechanism for adjusting the distance between the upper mold 2 and the lower mold 1.

[0031] Alignment mechanism, located on the four side walls of upper mold 2 and lower mold 1, is used for alignment of upper mold 2 and lower mold 1.

[0032] When it is necessary to connect the upper mold and the lower mold 1, the upper mold 2 and the lower mold 1 are respectively provided with threaded hole 7 and threaded hole 9. The connecting plate 3 is provided with sliding hole 17 and adjusting groove 15. Threaded post 13 is provided inside the sliding hole 17, and threaded post 24 is provided inside the adjusting groove 15. Threaded post 13 can slide in the sliding hole 17.

[0033] Among them, threaded post 13 can be threaded to threaded hole 7, and threaded post 24 can be threaded to threaded hole 9. Rotating threaded post 13 and threaded post 24 can connect the upper mold 2 and the lower mold 1, which can improve the adhesion of the two colors of the coating and improve the product quality.

[0034] When upper mold plate 10 and lower mold plate 8 of different thicknesses are installed between upper mold 2 and lower mold 1, the position of threaded post 13 in sliding hole 17 needs to be adjusted to adjust the movable distance between upper mold 2 and lower mold 1. The adjustment mechanism includes a ring 18 fitted on threaded post 14, a limit block 19 fixed on the ring 18, and a limit groove 16 on the connecting plate 3. The limit block 19 matches the limit groove 16. The position of threaded post 14 in the adjustment groove 15 needs to be adjusted. At this time, the ring 13 is adjusted to adjust the position of threaded post 14 in sliding hole 17. The limiting block 19 on the ring 18 is inserted into the limiting groove 16 of the corresponding thickness. Then, the threaded post 14 is passed through the ring 18 and rotated into the threaded hole 9 to complete the adjustment of the threaded post 14. When the threaded post slips, it can also limit the connection plate 3, which improves the stability of the connection plate 3. In addition, circular baffles are fixed on both the threaded post 13 and the threaded post 14 to facilitate the rotation of the threaded post 13 and the threaded post 14, and at the same time, it can prevent the connection plate 3 from falling off the threaded post 13 and the threaded post 14.

[0035] When the upper mold 2 is placed on top of the lower mold 1, the alignment mechanism includes protrusions 5 fixed around the upper mold 2 and concave blocks 6 fixed around the lower mold 1. The protrusions 5 and concave blocks 6 match each other. The protrusions 5 are inserted into the concave blocks 6, and the concave blocks 6 can align the protrusions 5. At the same time, it can also prevent the upper mold 2 from sliding on the lower mold 1. The bottom of the protrusions 5 is fixed with an upper magnetic block 11, and the top of the concave blocks 6 is fixed with a lower magnetic block 12, which further improves the convenience of alignment. It is worth noting that the magnetic poles of the facing surfaces of the upper magnetic block 11 and the lower magnetic block 12 are opposite, and the upper magnetic block 11 and the lower magnetic block 12 attract each other.

[0036] When workers need to cast the box lid, they first place the cast first-color outer lid onto the lower mold plate 8. Using a molding machine, the upper mold 2 is aligned with the lower mold 1 and placed on top of it, so that the protrusion 5 is inserted into the concave block 6. The second-color coating is added from the injection port 4. The second-color coating will enter between the upper mold plate 10 and the lower mold and bond and solidify with the first-color outer lid. After a period of time, the molding machine can be controlled to lift the upper mold 2. At this time, the threaded column 13 slides in the sliding hole 17 to limit the movement distance of the upper mold 2 and the lower mold 1, so that the movement distance between the upper mold 2 and the lower mold 1 is just right to open the upper mold plate 10 and the lower mold plate 8 and take out the product.

[0037] When different thicknesses of adhesive coating need to be poured, upper template 10 and lower template 8 of different thicknesses need to be used. At this time, it is necessary to adjust the position of threaded column 13 in the sliding hole 17, insert the limiting block 19 on the ring 18 into the limiting groove 16 of the corresponding thickness, and then pass the threaded column 14 through the ring 18 and rotate it into the threaded hole 9 to complete the adjustment of threaded column 13.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
