Description

Technical Field

[0001] The utility model relates to the field of cosmetics, in particular to a bottle blowing mold for special-shaped cosmetic containers. Background Art

[0002] Cosmetics are widely used in daily life. Cosmetic liquids or materials are stored in containers. Currently, cosmetic containers on the market are typically made of plastic, mostly transparent or white. They are typically formed using the blow molding process. The basic principle is to blow air into a hot preform inside a mold, thermoforming the preform along the mold's inner walls. After the mold separates, the bottle cools and takes shape.

[0003] The molds currently used in the production process are generally mirror-symmetrical and can produce common cylindrical bottles. However, when the sides of the bottles are set with convex or irregular curves, the existing molds cannot produce qualified bottles and cannot be printed or hot-stamped on the product surface. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a bottle blowing mold for special-shaped cosmetic containers.

[0005] The technical solution of the utility model is: a bottle blowing mold for special-shaped cosmetic containers, comprising:

[0006] an upper die, wherein a first molding surface is provided below the upper die;

[0008] a left slider, wherein a third forming surface is provided on the right side of the left slider;

[0009] a right slider, wherein a fourth forming surface is provided on the left side of the right slider;

[0010] The first molding surface, the second molding surface, the third molding surface and the fourth molding surface form a processing cavity.

[0011] Furthermore, transition slopes are provided on both sides of the first molding surface, the second molding surface, the third molding surface, and the fourth molding surface, respectively, so as to connect with each other and ensure smooth mold closing and mold opening.

[0012] Furthermore, lower sliding grooves are provided on the left and right sides of the lower mold, and a left slider and a right slider are slidably provided in the lower sliding grooves, thereby ensuring stable movement of the two during mold closing.

[0013] Furthermore, upper sliding grooves are respectively provided on the left and right sides of the upper portion, and the left slider and the right slider slide along the upper sliding grooves respectively, thereby ensuring stable movement of the left slider and the right slider.

[0014] Furthermore, limiting grooves are protruded on both sides of the lower sliding groove, and limiting blocks are respectively provided on the left and right sliding blocks, which are slidably arranged in the limiting grooves, thereby ensuring the stable movement of the left and right sliding blocks.

[0015] Furthermore, upper stop surfaces are provided inside the upper sliding grooves, and after the mold is closed, the left and right slide blocks respectively fit in with the upper stop surfaces, thereby ensuring the stability of the mold closing and avoiding damage to the molding surface.

[0016] Furthermore, lower stop surfaces are provided inside the lower sliding grooves, and after the mold is closed, the left and right sliders are respectively fitted with the lower stop surfaces, thereby ensuring the stability of the mold closing and avoiding damage to the molding surface.

[0017] Furthermore, the bottle blowing direction is the front-back direction.

[0018] Furthermore, thread grooves are respectively provided on the front sides of the upper die and the lower die. The thread grooves on the upper and lower sides are matched to ensure that an external thread can be naturally formed at the position of the bottle mouth during molding.

[0019] Furthermore, an upper driving source is provided on the upper mold, which drives the upper mold to move in a vertical direction, thereby ensuring mold closing and mold opening.

[0020] Furthermore, a left driving source and a right driving source are also provided on the left slider and the right slider respectively. Under the joint action of the left driving source and the right driving source, the left slider and the right slider can be closed and separated.

[0021] Furthermore, cooling channels are provided in the upper and lower molds. By providing cooling liquid in the cooling channels, smooth cooling after bottle blowing is ensured, ensuring smooth demoulding. Cooling channels can also be provided in the left and right sliders to ensure smooth demoulding.

[0022] Furthermore, a positioning groove and a positioning block are respectively provided between the upper mold and the lower mold. When the mold is closed, the positioning block is inserted into the positioning groove, thereby ensuring the stability of the mold closing.

[0023] The beneficial technical effect of the utility model is that by adding the left slider and the right slider, when processing special-shaped bottles, especially when there are undercuts on the left and right sides, the parting line can be effectively avoided from appearing on the undercut surface, which provides a reliable guarantee for the blowing of such products with uneven and complex curved surfaces, and at the same time provides a flat surface for subsequent printing or hot stamping on the side.

[0044] The right slider 4 has a fourth molding surface 401 provided on the left side of the right slider 4;

[0045] The first molding surface 101 , the second molding surface 201 , the third molding surface 301 and the fourth molding surface 401 form a processing cavity.

[0046] Furthermore, transition slopes 5 are provided on both sides of the first molding surface 101, the second molding surface 201, the third molding surface 301, and the fourth molding surface 401. The transition slopes 5 are connected to each other to ensure smooth mold closing and mold opening.

[0047] Furthermore, lower sliding grooves 6 are respectively provided on the left and right sides of the lower mold 2, and the left slider 3 and the right slider 4 are respectively slidably provided in the lower sliding grooves 6, thereby ensuring the stable movement of the two during mold closing.

[0048] Furthermore, upper sliding grooves 7 are respectively provided on the left and right sides, and the left slider 3 and the right slider 4 slide along the upper sliding grooves 7, respectively, thereby ensuring the stable movement of the left slider 3 and the right slider 4.

[0049] Furthermore, limiting grooves 8 are provided on both sides of the lower sliding groove 6, and limiting blocks 9 are provided on the left slider 3 and the right slider 4, respectively, and the limiting blocks 9 are slidably provided in the limiting grooves 8. This can better ensure the stable movement of the left slider 3 and the right slider 4.

[0050] Furthermore, an upper stop surface 10 is provided inside the upper sliding groove 7. After the mold is closed, the left slider 3 and the right slider 4 are respectively fitted with the upper stop surface 10 to ensure the stability of the mold closing and avoid damage to the molding surface.

[0051] Furthermore, a lower stop surface 11 is provided inside the lower sliding groove 6. After the mold is closed, the left slider 3 and the right slider 4 are respectively fitted with the lower stop surface 11 to ensure the stability of the mold closing and avoid damage to the molding surface.

[0052] Furthermore, the bottle blowing direction is the front-back direction.

[0053] Furthermore, thread grooves are respectively provided on the front sides of the upper die 1 and the lower die 2. By coordinating the thread grooves on the upper and lower sides, it is ensured that an external thread can be naturally formed at the position of the bottle mouth during molding.

[0054] Furthermore, an upper driving source is provided on the upper mold 1. The upper driving source drives the upper mold 1 to move in a vertical direction, thereby ensuring mold closing and mold opening.
