Description

Rotary mode changing blister machine

Technical Field

The utility model relates to the technical field of blister machines, in particular to a rotary mode-changing blister machine.

Background Art

The blister machine, also known as the thermoplastic forming machine, is a machine that blister-forms heated and plasticized thermoplastic plastic coils such as PVC, PE, PP, PET, HIPS, etc. into various shapes of advanced packaging decoration boxes, frames and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened thermoplastic plastic sheets such as PVC and PET are blister-formed into various shapes of vacuum covers, blister trays, bubble shells, etc. through molds. At present, some blister machines on the market usually have only one mold base, that is, one blister machine can only produce blister trays one by one, and the production efficiency is very low, because only one mold can be installed on the blister machine, and when a failure occurs, the entire mold needs to be replaced, which not only has low production efficiency, but also is very inconvenient to load and unload the mold.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

In this embodiment, as shown in Figures 1 to 6, it includes a blister machine body 1 and a molding assembly. The blister machine body 1 is the body of the thermoplastic molding machine, and the molding assembly is a thermoplastic mold assembly. The molding assembly includes a turntable 2. In this embodiment, the blister machine body 1 has a base and a top molding mechanism located above the base. The top molding mechanism is provided with a lifting rod, and the top of the lifting rod is provided with an upper mold seat.

The turntable 2 is rotatably connected to the base of the blister machine body 1. A plurality of cavities 3 are circumferentially arranged on the turntable 2, that is, the plurality of cavities 3 are distributed in a circular array along the circular turntable 2. A lower mold base 4 is installed in each cavity 3. Symmetrical protrusions 11 are arranged on the outer periphery of the lower mold base 4. A groove 12 cooperating with the protrusion 11 is arranged on the inner wall of the cavity 3. In the present embodiment, the protrusion 11 is in the shape of a vertically arranged triangular prism. Four protrusions 11 are equidistantly distributed on the outer peripheral wall of the lower mold base 4 in the circumferential direction, and the groove 12 on the inner wall of the cavity 3 is also in the shape of a triangular prism. The lower mold base 4 is circular, and the cavity 3 is also correspondingly circular. When the lower mold base 4 is placed in the cavity 3, the height of the lower mold base 4 is higher than the height of the cavity 3, which is conducive to the easy removal when replacing the lower mold base 4, and also facilitates the heat dissipation of the lower mold base 4.

In addition, a gap 13 is left between the outer wall of the lower die base 4 and the inner wall of the cavity 3. Due to the cooperation of the protrusion 11 and the groove 12, even if there is a gap 13 between the lower die base 4 and the cavity 3, it will not affect the installation of the lower die base 4, that is, the lower die base 4 can still be stably installed in the cavity 3. Since the protrusion 11 and the groove 12 are both triangular prisms, after the protrusion 11 and the groove 12 cooperate, one prism surface of the protrusion 11 is tightly against the corresponding concave prism surface of the groove 12 to form a triangular contact surface, which is very stable. The gap 13 between the lower die base 4 and the cavity 3 not only facilitates the loading and unloading of the lower die base 4, but also plays a very important role in the heat dissipation of the lower die base 4. At the same time, the lower die base 4 will not have a large-area contact with the cavity 3 and wear each other, thereby extending the overall service life of the mold.

A cavity 5 is provided in the lower mold base 4, and the cavity 5 is also a circular disc-shaped structure, which is used to install a circular blister mold 6 to make a circular blister disc. The circular inner wall of the cavity 5 is circumferentially provided with four right-angle notches 8 located at the four corners. The four right-angle notches 8 are used to install a square blister mold 7, that is, a lower mold base 4 can be used to install a square mold and a circular mold at the same time, so as to produce square blister discs and circular blister discs respectively, that is, two types of blister discs only need one pair of upper and lower mold bases 4, which is not only convenient for production, but also saves mold opening costs.

In addition, a through hole 9 is provided in the center of the bottom surface of the cavity 5 . The provision of the through hole 9 can prevent the blister mold from being adsorbed in the cavity 5 of the lower mold base 4 , which is not conducive to taking out the blister mold.

Further, the blister machine body 1 is provided with a telescopic rod 10 below the turntable 2, that is, the blister machine body 1 or the bottom of the turntable 2 is provided with a telescopic rod 10, the fixed end of the telescopic rod 10 is connected to the driving member, the movable end of the telescopic rod 10 is located in the through hole 9 or directly below the through hole 9, and the movable end of the telescopic rod 10 can rise axially along the through hole 9 to the outside of the through hole 9, when the blister mold is installed in the cavity 5, the telescopic rod 10 drops below the through hole 9, and does not affect the blister mold; when the blister disk in the blister mold is formed, it is necessary to remove the blister mold or demould the blister disk, the telescopic rod 10 rises quickly to lift the blister mold, and as the telescopic rod 10 rises and falls quickly, the blister mold is constantly pushed up, so that the blister mold forms a state of up and down vibration, so that the blister disk in the blister mold can be quickly separated from the blister mold. This facilitates demoulding, and when the blister mold needs to be removed, only the telescopic rod 10 needs to rise and push the blister mold up, so that the blister mold is separated from the cavity 5.

In addition, a silicone layer is provided at the top of the movable end of the telescopic rod 10, so that when the movable end of the telescopic rod 10 is lifting the blister mold, the telescopic rod 10 is prevented from hard collision with the blister mold to avoid damaging the blister mold and the telescopic rod 10, and the noise generated by the collision can be reduced.

An annular groove 14 is also provided on the bottom surface of the cavity 5. The annular groove 14 is arranged around the through hole 9. In this embodiment, the bottom of the annular groove 14 is an arc-shaped bottom surface. There are two annular grooves 14, which are concentrically distributed with different diameters. The purpose of this arrangement is to make the bottom surface of the lower mold base 4 dissipate heat more quickly.

The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
