Technical Field

[0001] This invention relates to the field of perfume bottle processing equipment technology, specifically to an injection molding machine for producing perfume bottle caps. Background Technology

[0002] Perfume is a product made by dissolving fragrance ingredients in ethanol. Sometimes, trace amounts of pigments, antioxidants, bactericides, glycerin, surfactants, and other additives are added as needed. It has a rich and fragrant aroma and is mainly used by spraying it on clothing, handkerchiefs, and hair to emit a pleasant scent; it is an important cosmetic product. Perfume bottles are containers used to hold perfume, and their production involves injection molding and transportation.

[0030] This invention provides an injection molding machine for manufacturing perfume bottle caps, such as... Figure 1-8As shown, the method for manufacturing perfume bottle caps includes a base 1, an injection module 9 fixedly mounted on the top of the base 1, a lower mold 2 fixedly mounted on the top of the injection module 9, an upper mold 3 arranged on the top of the lower mold 2, a die-casting cavity 22 formed on the top of the lower mold 2, and a base 7 fixedly mounted on the bottom of the upper mold 3. An injection hole 23 is formed at the bottom of the inner wall of the die-casting cavity 22, and the injection hole 23 communicates with the injection module 9. The injection module 9 is used to inject raw materials into the die-casting cavity 22, which is a conventional existing technology.

[0031] A vertical connecting pipe 71 is fixedly installed at the center of the bottom of the base 7. The upper end of the connecting pipe 71 passes through the base 7 and the upper mold 3, extending above the upper mold 3. Multiple sliding grooves 72 are formed around the center of the bottom of the base 7. A vertical support rod 73 is slidably fitted into each groove 72. An air ring 75 is provided between the connecting pipe 71 and the support rod 73. An extension section 751 is provided on the inner side of the air ring 75, and the air ring 75 and the extension section 751 are integrally formed. The air ring 75 is connected to the connecting pipe 71 through the extension section 751, and the outer side of the air ring 75 is fixedly bonded to the support rod 73.

[0032] It also includes an elastic sleeve 74 and rubber bands 76. The rubber bands 76 are looped around and pass through multiple support rods 73. The support rods 73 and the rubber bands 76 form a frame that can expand and contract. The elastic sleeve 74 is fitted over the frame and is stretched out. Therefore, under the action of elasticity, the inner wall of the elastic sleeve 74 is in close contact with the support rods 73, and the upper end of the elastic sleeve 74 is in close contact with the bottom of the base 7.

[0033] During operation, the bottom of the upper mold 3 presses against the lower mold 2, and the elastic sleeve 74 enters the die-casting cavity 22. Air is supplied into the connecting pipe 71, causing the air ring 75 to expand and bulge. The air ring 75 pushes the support rods 73 away from each other, and the support rods 73 expand the elastic sleeve 74. Next, the injection module 9 feeds the raw material into the die-casting cavity 22. This allows for the production of cylindrical bottle caps of different thicknesses according to requirements, facilitating subsequent processing, polishing, and decoration of the bottle cap's outer surface.

[0034] A small air pump 16 is fixedly installed on the top of the chassis 1, and a hose is fixedly installed on the top of the small air pump 16. The hose can extend into the connecting pipe 71.

[0035] A molding module is located directly above the upper mold 3. The molding module cuts the top of the bottle cap to make the bottle cap into a polygon.

[0036] The molding module consists of a disc 4, a sphere 5, and a cutting tool 6. The sphere 5 is pivotally connected to the center of the disc 4 and can rotate left and right. The cutting tool 6 is positioned above the sphere 5, with its lower end angled and penetrating the sphere 5. Multiple slots 51 are provided on the top left side of the sphere 5. A positioning block 41 is welded to the top of the disc 4, and an insert plate 42 is inserted into the positioning block 41, engaging with the slots 51. By inserting the insert plate 42 into different slots 51, the tilt angle of the cutting tool 6 can be adjusted, thus allowing different degrees of bevel to be cut on the top edge of the bottle cap.

[0037] A cavity 52 is formed inside the sphere 5, and a motor 53 is fixedly installed inside the cavity 52. ​​A gear 54 is welded to the drive shaft of the motor 53. A toothed groove 61 is formed on the side of the cutting tool 6 near the cavity 52, and the gear 54 meshes with the toothed groove 61. The motor 53 drives the gear 54, which in turn drives the cutting tool 6 to move up and down.

[0038] A ring 12 is provided on the outer side of the disc 4, and the ring 12 is pivotally connected to the disc 4. The disc 4 can rotate around its center. Support rods 11 are welded to both the front and rear sides of the ring 12, and the support rods 11 are fixedly inserted into the base plate 1. The top edge of the ring 12 is engraved with scale lines 121 around its center, and an indicator 43 is welded to the top edge of the disc 4. This allows the operator to clearly know the rotation angle of the ring 12.

[0039] Slots 51 are distributed around the center of sphere 5, and the angle between two adjacent slots 51 is 10°.

[0040] A secondary groove 721 is provided on the side of the slide groove 72 away from the connecting pipe 71. A shielding plate 77 is slidably fitted in the secondary groove 721. One end of the shielding plate 77 is connected to the body of the support rod 73. When the support rod 73 moves toward the connecting pipe 71, the shielding plate 77 extends out from the secondary groove 721 to shield the slide groove 72. The elastic sleeve 74 is made of high temperature resistant material. The upper end of the elastic sleeve 74 is laid flat and unfolded to fit tightly against the bottom of the base 7.

[0041] The Chinese patent application discloses "a high-elasticity, high-temperature resistant, flame-retardant film" (CN202022351887.2). Therefore, the elastic film 74 is a conventional technical means, and its specific structure and composition are the same as those of the prior art, so it will not be described in detail.

[0042] The lower mold 2 has multiple snap-fit ​​grooves 21 on its top. The bottom of the upper mold 3 is welded with a cylinder 31 at the snap-fit ​​groove 21, and the cylinder 31 can extend into the snap-fit ​​groove 21. An air pump 8 is fixedly installed on the top of the chassis 1. A hollow vertical rod 81 is fixedly installed on the top of the air pump 8. The vertical rod 81 passes through the lower mold 2 and extends into the snap-fit ​​groove 21. An air pipe 82 is fixedly installed at the working end of the air pump 8, and the air pipe 82 is connected to the inside of the vertical rod 81.

[0043] During operation, the air pump 8 extracts the air from the locking groove 21, and the vertical rod 81 tightly sucks the cylinder 31, so that the upper grinding mold 3 and the lower grinding mold 2 are tightly attached together.

[0044] An electric push rod 13 is fixedly installed on the top of the chassis 1. A rotating shaft 14 is pivotally connected to the upper end of the electric push rod 13. The rotating shaft 14 is arranged horizontally, and the end of the rotating shaft 14 away from the electric push rod 13 is welded to the upper mold 3.

[0045] During operation, the air pump 8 inflates and blows air into the locking groove 21, while the electric push rod 13 extends to lift the upper mold 3. The semi-finished product is then removed, and the upper mold 3 is flipped so that the base 7 faces upward. The semi-finished product is then placed on the support rod 73, and the surface of the semi-finished product is processed using the plastic module.

[0046] A control module 15 is fixedly installed on the top of the chassis 1. The control module 15 controls the operation of various electronic components.

[0047] In summary, this injection molding machine for producing perfume bottle caps features a lower mold 2 and an upper mold 3. Through the cooperation of a base 7, support rod 73, elastic band 76, connecting pipe 71, and air ring 75, it forms a frame whose shape can shrink and expand, thus enabling the production of cylindrical bottle caps of varying thicknesses. Furthermore, through the cooperation of a disc 4, a sphere 5, and a cutting tool 6, the bottle caps can be further processed to produce caps of different polygonal shapes. This allows a single machine to produce various bottle caps, thereby reducing production costs.
