Composite mold of pressure cooker lid

Abstract

A composite die for a pressure pot lid comprises an upper die plate (2) and a lower die plate (1); guide columns (12) are arranged at two ends between the upper die plate (2) and the lower die plate (1), and fixed on the lower die plate (1); a pot lid concave die (11) is fixed on lower die plate (1); a punching convex die (21) and a pitting convex die (22) are fixed on the upper die plate (2); a punching concave die (14) matched with the punching convex die (21) and a pitting concave die (15) matched with the pitting convex die (22) are fixed on the a pot lid concave die (11). The composite die overcomes the disadvantages in the prior pot lid of superabundant operating positions in processing operation, long operation procedure, easy waste product forming, etc. By adopting the composite die for the pressure pot lid, the operation procedure of the prior process is shortened, and the product quality is effectively ensured.

Description

technical field [0001] The invention relates to a composite mold for a pressure cooker lid. Background technique [0002] The pot cover of existing pressure cooker has five operations when making, namely: 1. pressure cooker cover presses handle pit (hereinafter referred to as press pit, as figure 1 shown), ②Punching valve holes (including three valve holes, such as figure 2 shown), ③ press the limit file (limit mark, such as image 3 shown), ④ press the opening and closing mark (such as Figure 4 shown), ⑤permanent identification (such as Figure 4 shown). The lid of the existing pressure cooker requires 4 pairs of molds during production, 1). First use the first pair of molds to press the pressure cooker cover on the first equipment; 2). Use the second pair of molds on the second equipment Punch the valve hole (three valve holes); 3). Press the limit gear on the third device; 4). Press the opening and closing mark and permanent mark on the fourth device. [0003] The...

AI Technical Summary

Problems solved by technology

[0003] The processing technology of the existing pressure cooker cover has many stations and long operation process, and the product will easily cause bumps after repeated turnover, which will affect the surface quality of the product; the pressing handle pit and the punching valve hole (three valve holes) are operated separately, and the If the product positioning is inaccurate during the operation of the staff, it is easy to cause one-sided punching and waste products

[0004] The processing technology of the existing pressure cooker cover requires 4 sets of equipment, the production site is large, and 4 employees are required to operate, that is, the demand for manpower and equipment is large, and the energy consumption is large; due to the operation on multiple presses, there are many potential safety hazards
