Embodiment Construction

[0013] The present invention will be described in further detail below by means of specific embodiments:

[0014] The reference signs in the drawings of the specification include: lower valve body 1, valve core 11, air inlet 12, air outlet 13, upper valve body 2, valve stem 21, diaphragm 3, lever handle 4, extension spring 41, column 42 , clip 5.

[0015] The embodiment is basically as attached figure 1 And attached figure 2 Shown:

[0016] The lever diaphragm vacuum valve for die-casting in this solution includes a valve body, a diaphragm 3, and a valve stem 21. The valve stem 21 slides inside the upper valve body 2. The lower end of the valve stem 21 is connected to the diaphragm 3, and the valve core is below the diaphragm 3. 11. The valve core 11 and the lower valve body 1 are integrally manufactured and formed. The two sides of the valve core 11 are respectively provided with an air inlet 12 and an air outlet 13. The air inlet 12 and the air outlet 13 pass through the...

Abstract

The invention relates to the technical field of diaphragm cutoff devices and discloses a lever diaphragm vacuum valve for die casting. The lever diaphragm vacuum valve comprises a valve body, a diaphragm and a valve rod. The valve rod is sleeved with the valve body. The lower end of the valve rod is connected with the diaphragm. A valve element is arranged below the diaphragm. An air inlet and an air outlet are formed beside the valve element. The air inlet and the air outlet are communicated with a gap between the valve element and the diaphragm. A lever handle is arranged above the valve rod and hinged to the valve rod through a stand column on the valve body. One end of the lever handle is connected with the valve body through a tension spring. The middle segment, located over the valve rod, of the lever handle is provided with a sliding wheel. The sliding wheel makes contact with the valve rod. The end, away from the tension spring, of the valve body is provided with clamping pieces. By the adoption of the scheme, lever downwards-pressing replaces screw rotating downwards-pressing, opening and closing are faster, operation is efficient, control is more convenient and faster, and die casting efficiency is improved effectively.

Description

technical field [0001] The invention relates to the technical field of diaphragm cutting devices. Background technique [0002] The vacuum die-casting method is to extract the gas in the cavity, and the molten metal fills the cavity in a vacuum state, so less gas is involved, the mechanical properties of the casting are high, and the vacuum die-casting inherits and maintains the advantages of the ordinary die-casting method. The vacuum degree is in the range of 52-82KPa (380-600mmHg), which can be obtained by mechanical pumps, and the vacuum degree requirements for thin-walled and complex die-casting parts will be higher. Vacuum die-casting has the following advantages: vacuum die-casting method can eliminate or reduce the pores inside die-casting parts, improve the mechanical properties and surface quality of die-casting parts, and improve the coating performance; vacuum die-casting method greatly reduces the back pressure of the cavity and can use lower For alloys with lo...
