The support block propped up with solid plate lower end, it is ensured that mould is placed horizontal.
Being supplemented as one kind to technical solution described in the utility model, described solid plate one end is provided with 4 guide sleeves,
The solid plate upper end is provided with 4 guide sleeves, and the moving platen lower end is provided with the guide post coordinated with guide sleeve and guide post is in guide sleeve
In slide up and down.
Supplemented as one kind to technical solution described in the utility model, the bottom of the barrel is disposed with spreader.
Ensure that high-temperature liquid metal smoothly enters die cavity.
Supplemented as one kind to technical solution described in the utility model, 3 and mould are disposed with around the core rod
The exhaust block of chamber connection, discharges the gas in die cavity, avoids forming bubble in die cavity.
Beneficial effect：A kind of compression mod of electric power tool shell is the utility model is related to, due to aluminium alloy pouring temperature mistake
Height, type wall is washed away in metal stream front can cause erosion phenomenon, therefore will be as far as possible with less injection speed, by will commonly flow
Road sets the transition part of upward bending close to one end of die cavity so that and the melt of high-voltage high-speed is buffered when entering die cavity, into
And injection speed is effectively reduced, the utility model has the features such as charging is steady, improves product quality.
