Pill pressing die

Abstract

The utility model provides a pill pressing die, which relates to the field of medicine processing and comprises a lower cylinder, an upper die holder is placed on the upper portion of the lower cylinder, an upper cylinder is arranged in the center of the bottom end face of the upper die holder, and a first hemispherical groove is formed in the bottom end face of the upper cylinder. Through the arrangement of the pushing mechanism, after discharging, only the right end of a pressing handle needs to be loosened, then a round limiting plate drives a square pushing rod and a square table to fall back downwards under the elastic force effect of a spring outside the square pushing rod, and therefore the square table can be automatically adjusted to the original position without reversing a drum type structure. The pill pressing mold is simpler and more convenient to operate; the pill pressing die solves the problems that when an existing pill pressing die is used for discharging, a rotating cylinder needs to be manually twisted to enable a square table and a pressing disc to move upwards together, then discharging is conducted, and in order to not affect the pressing work of a next pill, the rotating cylinder needs to be reversely rotated to enable the square table to be adjusted to the original position, and consequently operation of the pill pressing die is too tedious.

Description

TECHNICAL FIELD

[0001] The utility model relates to medicine processing technical field especially, relate to a pill pressing mould. BACKGROUND

[0002] In the pharmaceutical, food and health care products industries, pills are a very common dosage form. Pills have many advantages such as convenient to take, easy to store, and can mask the unpleasant odor of the drug, and are therefore widely used in the production of various products. In the production process of pills, a pressing mold is needed.

[0003] For example, the pill pressing mold in the prior art (the pill pressing mold disclosed in the prior patent application No. 202321432347.4) can conveniently unload the pills pressed and formed inside the hemispherical mold groove, reducing the difficulty of unloading for personnel. However, when unloading, the square table and the pressing plate need to be moved upward together by manually twisting the rotating cylinder, and then unloading is performed. After unloading, in order not to affect the pressing work of the next pill, the rotating cylinder needs to be reversed to adjust the square table back to the original position, resulting in that the operation of the pill pressing mold is too cumbersome. In addition, the existing pill pressing mold lacks effective fixing structure at the bottom, resulting in poor stability of the pill pressing mold when used on a smooth table top. SUMMARY

[0004] The disclosed embodiment relates to a pill pressing mold. By providing a pushing mechanism, when unloading, the worker only needs to manually press the right end of the pressing handle downward, which can move the square table, the upper cylinder and the upper mold seat upward in a straight line, and then unloading work can be performed. After unloading, only the right end of the pressing handle needs to be released, and then the circular limiting plate, the square pushing rod and the square table are brought down under the action of the spring force outside the square pushing rod, so that the square table can be automatically adjusted back to the original position without reversing the rotating cylinder structure, making the operation of the pill pressing mold more convenient.

[0005] In the first aspect of the disclosure, a pill pressing mold is provided, which specifically comprises: a lower cylinder, an upper mold seat is placed on the upper part of the lower cylinder, an upper cylinder is arranged at the center part of the bottom end face of the upper mold seat, and a first hemispherical groove is formed in the bottom end face of the upper cylinder; a circular groove is formed in the center part of the upper end face of the lower cylinder, a first conical groove is formed in the bottom end face inside the circular groove, a square sliding groove is formed in the first conical groove, a square table is slidably connected inside the square sliding groove, a second conical groove is formed in the upper end face of the square table, and a second hemispherical groove is formed in the second conical groove; a base is fixedly connected to the bottom of the lower cylinder through four supporting columns, and a pushing mechanism is arranged on the upper part of the base at the bottom of the square table; and an adsorptive fixing assembly is arranged at the bottom of the base.

[0006] In at least some embodiments, six guide columns are arranged in a ring array at the edge of the upper end surface of the lower cylinder; and the diameter of the base is larger than the diameter of the lower cylinder.

[0007] In at least some embodiments, six positioning holes are arranged in a ring array at the edge of the upper end surface of the upper die holder, and an annular anti-skid stripe is arranged on the outer circumferential surface of the upper die holder.

[0008] In at least some embodiments, the pushing mechanism comprises a square pushing rod, a driving column, a circular limiting plate, a rotating frame, a pressing handle, a strip-shaped sliding port and a rotating support block. The square pushing rod is fixedly connected to the middle part of the bottom end surface of the square table, and penetrates through the bottom of the lower cylinder. The lower end of the square pushing rod is fixedly connected with the driving column, and the lower side of the outer part of the square pushing rod is fixedly connected with the circular limiting plate. A spring is arranged between the circular limiting plate and the lower cylinder outside the outer part of the square pushing rod. The rotating frame is rotatably connected with the rotating support block at the inner right side, and the rotating support block is fixedly connected to the upper end surface of the base. The pressing handle is fixedly connected to the right end of the rotating frame. A strip-shaped sliding port is arranged on each of the left sides of the front and rear end surfaces of the rotating frame, and the two strip-shaped sliding ports are respectively slidably connected with the outer circumferential surfaces of the front and rear ends of the driving column.

[0009] In at least some embodiments, when the right end of the pressing handle is in a downward pressing state, the left side of the rotating frame is upwardly rotated, and the driving column moves upwardly linearly with the square pushing rod and the square table.

[0010] In at least some embodiments, the adsorption type fixing assembly comprises four suction cups, four communication pipes, an air pipe and a threaded sealing cover. The four suction cups are fixedly connected to the bottom end surface of the base. The four suction cups are communicated through the four communication pipes.

[0011] The pill pressing mold has the following beneficial effects:

[0012] Through the arrangement of the pushing mechanism, when discharging, the operator only needs to manually press the right end of the pressing handle downward, so that the square table, the upper cylinder and the upper die holder can move upwardly linearly. Then, the discharging work can be performed. After discharging, the right end of the pressing handle is loosened, and then the circular limiting plate moves downwardly with the square pushing rod and the square table under the elastic force of the spring outside the square pushing rod, so that the square table can be automatically adjusted to the original position without reversing the rotating drum structure. Therefore, the pill pressing mold is more convenient to operate, has a simple structure and high practicability.

[0013] Through the arrangement of the four suction cups, when the pill pressing mold is used on the smooth table top, the four suction cups are adsorbed and fixed to the smooth table top by pressing the base downward, so that the pill pressing mold can be effectively fixed on the smooth table top, thereby improving the stability of the pill pressing mold when used on the smooth table top.

[0014] Through the arrangement of the communication pipe, the air pipe and the threaded sealing cover, when the four suction cups need to be separated from the smooth table top, the threaded sealing cover is only needed to be unscrewed from the upper end of the air pipe, so that the four suction cups lose the negative pressure effect, thereby the four suction cups can be easily separated from the smooth table top, and the convenience of the pill pressing mold when being taken off from the smooth table top is improved.
