When the inclined surface of number 19 bottom end of mold insert, horizontal active force part is assigned on vertical direction, thus push No. two mold inserts 19 to
Upper movement, excessive injection molding sizing material 21 is compressed to the position of setting and is injected into be molded into using the top protrusion of No. two mold inserts 19
Bubble and the shrinkage cavity of injection-molded finished 9 inside and surface remaining are reduced so that the bubble of interiors of products be extruded in the inside of product 9,
After squeezing one end time, the hydraulic push rod 22 of 20 front end of hydraulic cylinder is retreated, and No.1 mold insert 18 is pulled back, No.1 mold insert 18 is lost
No. two mold inserts 19 of effect under the double action of gravity and reset spring 27 under fall back to original position, prepare next operation,
During this, the ball 30 of activity installation can effectively reduce the friction with No. two mold inserts 19 on 18 front end inclined surface of No.1 mold insert
Power prevents No.1 mold insert 18 and No. two mold inserts 19 from causing movement that setting position is not achieved because friction is excessive, and then influences finally
Squeezing effect opens front template 5 and rear pattern plate 6 after product is cooled and shaped completely, can will be molding using die ejector pin 16
Product ejects front cavity 7 and rear cavity 8, can carry out next subjob after molding again.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
