Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic stamping equipment, in particular to a discharge mechanism for aluminum-plastic film stamping forming. Background Art

[0002] Aluminum-plastic has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc. It is non-toxic, non-absorbent, dust-proof, and does not peel or desquamate. It has excellent sealing performance. Therefore, in the medical field, many medicine bottles' plastic caps or rubber caps are wrapped with a layer of aluminum-plastic cap. This aluminum cap is made of aluminum-plastic plate by stamping through a stamping die machine.

[0003] For example, the patent application with application number CN202011016775.X includes a machine base, a lower die base is fixedly installed on the top of the machine base, a frame located on one side of the lower die base is fixedly connected to the top of the machine base, an upper die base located on the lower die base is fixedly installed on the frame, a lower module is fixedly installed on the top of the lower die base, and a first hydraulic rod is provided on both sides of the top of the upper die base. The aluminum-plastic stamping die machine, through the design of the metal diaphragm structure that can be raised up and down in the middle of the upper die, when the aluminum-plastic plate is stamped into an aluminum-plastic cover, the pressing block is further moved downward to cooperate with the lower die to further stamp the middle of the formed aluminum-plastic cover, so that the thickness value of the middle part of the formed aluminum-plastic cover is small, so that when the aluminum-plastic cover is applied to the mouth of the medical oral liquid bottle in the later stage, it is convenient to use a straw to pierce the aluminum-plastic cover, so as to avoid the problem that when the aluminum-plastic cover is thick, the straw is not easy to pierce, affecting the use, and when the aluminum-plastic cover is thin, the strength of the oral liquid bottle is not enough.

[0004] However, when the above-mentioned aluminum-plastic stamping die machine is in use, the control linkage shaft drives the piston to move upward, so that the metal diaphragm bulges upward, and a negative pressure space is formed between the metal diaphragm and the formed aluminum-plastic cover, so that the aluminum-plastic cover and the upper mold move upward as a whole and separate from the lower mold. If the negative pressure space has a large negative pressure, the metal diaphragm cannot be removed from the upper mold; if the negative pressure space has a small negative pressure, the metal diaphragm cannot be removed from the lower mold, thereby reducing the unloading effect of the aluminum-plastic stamping die machine. It is urgent to design an unloading mechanism for aluminum-plastic film stamping to solve the above-mentioned problems. Utility Model Content
