The specific embodiment
In the utility model, the structure of described For Drain Valve of Washing Machine valve plug as shown in Figure 1, valve plug 10 is the semi-closed structure of upper end closed lower end opening, the perisporium of valve plug 10 is ripple struction
The utility model proposes a kind of mould of For Drain Valve of Washing Machine valve plug, as shown in Figure 2, this mould comprises bed die 1, cover die 2, a plurality of core rod 3 and die sleeve, core rod 3 is fixed on the bed die 1, die sleeve is comprised of two Hough bars 4, Hough bar 4 is slidingly mounted on the bed die 1 by dovetail groove, but Hough bar 4 horizontal slip on bed die 1; The cavity that bed die 1, cover die 2, core rod 3 and die sleeve surround has consisted of the die cavity of valve plug.
Above-mentioned mould also comprises the Pneumatic demould mechanism 5 for the described valve plug of jack-up, is provided with air flue 6 at bed die 1, is provided with the through hole that is communicated with air flue 6 in each core rod 3, and Pneumatic demould mechanism 5 is installed in the through hole and can slides up and down in through hole.
As shown in Figure 3; valve plug is moulding in mould; as shown in Figure 4; in the valve plug knockout course; after two Hough bars 4 of die sleeve are opened; in air flue 6, input gases at high pressure; promoting Pneumatic demould mechanism 5 under pneumatic action moves upward valve plug jack-up; valve plug can be sloughed from core rod 3 easily, greatly facilitates the stripping operation of valve plug, has improved the operating efficiency of the valve plug demoulding; and; thereby can promptly promote Pneumatic demould mechanism 5 with valve plug jack-up at knockout course mesohigh gas, the ripple struction of valve plug should not damage, thereby has improved the finished product rate of valve plug.
When specific design, Pneumatic demould mechanism 5 is complementary with the through hole of core rod 3, and in the forming process of carrying out valve plug, the stroke of Pneumatic demould mechanism 5 is zero, Pneumatic demould mechanism 5 structure that is combined as a whole in core rod 3.
In the specific embodiment, as shown in Figure 3, Pneumatic demould mechanism 5 is comprised of demoulding slide block 51 and screw rod 52, and demoulding slide block 51 and screw rod 52 are threaded connection, and moves upward valve plug jack-up thereby drive demoulding slide block 51 by air pressure lead-screw 52.In concrete the application, by tightening or unclamping being threaded between demoulding slide block 51 and the screw rod 52, can realize the accurate adjustment to demoulding slide block 51 positions.
Extremely shown in Figure 4 such as Fig. 2; it is up big and down small inverted trapezoidal structure that the upper end of demoulding slide block 51 is designed to cross section; vertical motion that can conveniently stripped slide block 51, and can increase the contact area of demoulding slide block 51 and valve plug bottom, thus damage to the valve plug bottom avoided in knockout course.
Certainly, in actual applications, Pneumatic demould mechanism 5 can directly adopt demoulding slide block 51, and does not adopt screw rod 52 structures, directly demoulding slide block 51 is placed in the through hole, equally also can realize demoulding functions.
In the valve plug knockout course, because the impulsive force of gases at high pressure is larger, therefore need to the movement travel of Pneumatic demould mechanism 5 be limited, gone out by demoulding slide block 51 or breakage to avoid valve plug.
