Description

Technical Field

[0001] This utility model relates to a cosmetic bottle cap forming mechanism. Background Technology

[0002] Cosmetic bottles are primarily used for containing cosmetics. A cosmetic bottle generally consists of two parts: the bottle body and the cap. The bottle body is typically made of materials such as ceramic, glass, or crystal, while the cap is mostly made of plastic, with a few being metal. Plastic caps are generally produced through injection molding, while metal caps are typically produced through casting. With the expansion and changes in the variety and market of cosmetics, and the accelerated pace of product updates, existing cosmetic bottles can no longer meet market demands. Simultaneously, as the external structure and aesthetics of products increasingly influence sales, designing styles that appeal to consumers has become essential. To meet market demands and the needs of increasing competition, our company has designed a new type of cap; however, the production of this cap requires the design of a corresponding molding mechanism. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a cosmetic bottle cap forming mechanism that is easy to use, simple to operate, highly automated, and capable of realizing the casting and molding of bottle caps and the automatic demolding of bottle caps. It is practical and widely used.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A cosmetic bottle cap forming mechanism includes an upper mold, a lower mold, a mold core one, and a mold core two, which form a mold cavity.

[0006] The upper and lower molds are provided with slide rail one and slide rail two. Mold core one is set in slide rail one and mold core two is set in slide rail two. The slide rail one and slide rail two guide the movement direction of mold core one and mold core two.

[0007] The upper mold and the lower mold are provided with a bottle cap shape shaping structure in the middle. The bottle cap shape shaping structure includes a groove structure, an arc surface structure, an annular groove structure one and an annular groove structure two.

[0008] The mold core has a concave surface at one end, and a pouring gate is provided around the concave surface; the pouring gate facilitates the entry of the poured molten metal into the mold cavity.

[0009] One end of the mold core is provided with a bottle cap inner cavity shaping structure, which achieves the shaping of the inner shape of the bottle cap through the bottle cap inner cavity shaping mechanism.

[0010] Preferably, both mold core one and mold core two are provided with mounting grooves; the mounting grooves facilitate the connection between mold core one and mold core two and mechanisms such as cylinders and oil cylinders, thereby enabling back-and-forth movement and achieving the effects of casting and molding, and demolding after molding.

[0011] Preferably, the lower mold is provided with multiple pouring holes, and pouring channel one, pouring channel two and pouring channel three are formed between the upper mold and the lower mold, and the pouring holes are connected to pouring channel one, pouring channel two and pouring channel three.

[0012] The multiple pouring channels increase the convenience of pouring, enable rapid pouring, and improve the quality of pouring.

[0013] Preferably, the upper and lower molds are provided with air channels; the design of the air channels facilitates the discharge of air during pouring, thereby reducing the internal pressure of the equipment and improving the quality of the poured bottle caps.

[0014] Preferably, the upper mold is provided with a second coolant channel, and the lower mold is provided with a first coolant channel, with the first coolant channel and the second coolant channel respectively located on the inner side of the lower mold and the upper mold.

[0015] The beneficial effects of this utility model are as follows: This utility model forms a sealed casting cavity through the upper mold, lower mold, mold core one, and mold core two; through the groove structure, arc surface structure, annular groove structure one, annular groove structure two, and casting channel, the casting and molding operation of the bottle cap is realized; through the setting of coolant channel one and coolant channel two, the rapid cooling and molding operation of the bottle cap is realized; through the moving operation of mold core one and mold core two, the automatic demolding operation of the bottle cap is realized, thus realizing the automation of bottle cap production. It has practicality and wide applicability. Attached Figure Description

The bottle cap shape shaping structure includes a groove structure 14, an arc-shaped surface structure 15, an annular groove structure one 16, and an annular groove structure two 17.

[0027] Furthermore, one end of the mold core 1 is provided with a concave surface 31, and the concave surface 31 is provided with a pouring gate 32 around its perimeter.

[0028] Furthermore, one end of the mold core 2 is provided with a bottle cap inner cavity shaping structure 41.

[0029] Furthermore, both mold core 1 and mold core 2 are provided with mounting grooves 33, which are connected to drive mechanisms such as cylinders and oil cylinders.

[0030] Furthermore, the lower mold 2 is provided with a plurality of pouring holes 6, and a pouring channel 10, a pouring channel 21 and a pouring channel 32 are formed between the upper mold 1 and the lower mold 2, and the pouring holes are connected to the pouring channel 1, the pouring channel 2 and the pouring channel 3.

[0031] Furthermore, air passages 13 are provided on the upper mold 1 and the lower mold 2.

[0032] Furthermore, the upper mold 1 is provided with a second coolant channel 18, and the lower mold 2 is provided with a first coolant channel.

[0033] Furthermore, the upper mold 1 and the lower mold 2 are provided with positioning holes 5, and guide posts (not shown) are provided in the positioning holes 5.

[0034] Furthermore, the bottle cap of this utility model includes a flange 20, an annular boss 21, a cap body 22 and a cap top 23, wherein the cap top is provided with an arc-shaped surface 24.

[0035] Furthermore, the arc-shaped surface matches the concave surface structure of the mold core.

[0036] Furthermore, the shape of the cover matches the shape of the groove structure.

At the same time, the mold core one and mold core two are installed and calibrated. During operation, the upper mold, lower mold, mold core one, and mold core two are closed to form a mold cavity. Then, the casting operation is performed. The molten metal enters the mold cavity through the casting hole, casting channel one, casting channel two, and casting channel three. When a certain time or a certain amount is reached, the injection stops. Subsequently, the coolant in the coolant channel circulates rapidly (or can circulate continuously as needed) to remove heat, allowing the bottle cap to cool and solidify quickly. Then, the upper mold and lower mold separate, and mold core one and mold core two move to the sides to achieve the demolding operation.

[0042] The casting channel 1, casting channel 2, and casting channel 3 of this utility model can also be used as slag collection bags to collect residual metal slag.
