Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
Example (b): the improved structure that the 1 slider of front mould was taken out to one side, including front mould 1 and back mould 15, be fixed with front mould benevolence 4 and back mould benevolence 17 on front mould 1 and the back mould 15 respectively, be equipped with the chamber in order to form the product of treating processing between front mould benevolence 4 and the back mould benevolence 17.
Front mould 1 includes panel 2 and the A board 3 with 4 fixed connection of front mould benevolence, and panel 2 and A board 3 can part each other, and the installation is fixed with shovel machine 6 on the panel 2, and the mounting groove 26 that runs through the panel 2 surface is seted up to the upside of panel 2, and it has fixing bolt 27 to peg graft in the mounting groove 26, fixing bolt 27's bottom and shovel machine 6's upper surface threaded connection, and the bottom surface of fixing bolt 27's nut contradicts with the upper surface of panel 2. Shovel 6 slant right side sets up and during shovel 6 right side bottom inserted A board 3, offer on the A board 3 and supply the appearance groove 7 that shovel 6 right bottom placed. Have slider seat 5 along the sliding connection of A board 3 side by side, the left side fixedly connected with cushion 28 of slider seat 5, the left end of slider seat 5 rotates and is connected with slider mold insert 8, and slider mold insert 8 slant left side pierces through front mould benevolence 4 and stretches into fashioned chamber, is equipped with on A board 3 and supplies slider mold insert 8 male mold insert groove 9, and the width of mold insert groove 9 is greater than the diameter of slider mold insert 8.
In traditional mould, shovel machine 6 directly shifts up along with panel 2 usually under injection molding machine power, shovel machine 6 conflicts slider seat 5 and moves right, and slider mold insert 8 slides along mold insert groove 9, and slider seat 5 drives slider mold insert 8 and breaks away from the product upper surface in the chamber between front mould benevolence 4 and back mould benevolence 17, reaches the effect that slider mold insert 8 and product upper surface break away from, and the right side fixedly connected with dog 10 of A board 3 is with the stroke that restricts slider seat 5 and move right. Because the sliding resistance of the sliding block seat 5 is large, the driving force required when the shovel machine 6 abuts against the sliding block seat 5 is large, and long before, the surface of the shovel machine 6 is easy to scratch or wear, so that the situation that the shovel machine 6 is frequently replaced by a die is caused.
In order to overcome the problem of quick abrasion of the shovel machine 6, a limit screw 11 is inserted into a stop block 10, the limit screw 11 and the stop block slide relatively, the left end of the limit screw 11 is in threaded connection with the right end of the slider seat 5, a side sliding spring 12 is arranged between a nut at the right end of the limit screw 11 and the right surface of the stop block 10, and the side sliding spring 12 is in a compressed state during mold closing. When panel 2 during the rebound under the effect of injection molding machine, the elasticity of sideslip spring 12 resumes, and sideslip spring 12 moves slider seat 5 right through spacing screw 11 drive, and the supplementary slider seat 5 of sideslip spring 12 moves right in order to reduce shovel machine 6 and to the drive power of slider seat 5 to reduce the condition that shovel machine 6 surface produced the damage.
In addition, a spring groove 13 is arranged on the A plate 3, an opening spring 14 is arranged in the spring groove 13, and the opening spring 14 is in a compressed state to assist in pushing the panel 2 to move upwards when the panel 2 and the A plate 3 are opened.
Rear die 15 includes B board 16, the bottom side fixedly connected with fixing base 18 of B board 16, the bottom side and the injection molding machine fixed connection of fixing base 18, the hollow liftout groove 19 that is equipped with in middle part of fixing base 18, sliding connection has ejector pin plate 20 and ejector pin plate 21 down in the liftout groove 19, the lower surface of going up ejector pin plate 20 passes through fixed connection with the upper surface of ejector pin plate 21 down, the inside of going up ejector pin plate 20 is equipped with a plurality of ejector pin 22, ejector pin 22 upwards pierces through ejector pin plate 20, B board 16 and rear die core 17, the upper end of ejector pin 22 will be in the product lower surface top in the cavity between rear die core 17 and front die core 4 and leave rear die core 17, be convenient for the product and the drawing of patterns of rear die core 17. The lower surfaces of the ejector rods 22 are fixed with convex disks 23, and the bottom sides of the upper ejector plate 20 are provided with convex grooves 24 for limiting the convex disks 23. The lower surface of the lower ejector plate 21 is fixedly connected with a push rod 25, the push rod 25 penetrates out of the lower end of the fixed seat 18, the push rod 25 is connected with the injection molding machine, and the injection molding machine can push the ejector rod 22 to move through the push rod 25 under the action of the injection molding machine.
The action process is as follows:
opening the mold for the first time: panel 2 moves up under the effect of injection molding machine, and panel 2 and A board 3 separate each other, and shovel machine 6 promotes slider seat 5 and moves to the right, and sideslip spring 12 assists slider seat 5 to move to the right, and die sinking spring 14 assists panel 2 and A board 3 to separate. The slider seat 5 moves to the right in-process drives the slider insert 8 to break away from the upper surface of the product, the slider seat 5 moves to the right and collides with the left side of the stopper 10 and does not slide any more, and the slider insert 8 is not completely broken away from the slider seat 5 at this moment.
Opening the die for the second time: the slide block insert 8 is not completely separated from the slide block seat 5, the shovel machine 6 drives the A plate 3 to move upwards through the slide block seat 5 under the continuous pulling of the injection molding machine, the front mold core 4 and the rear mold core 17 are separated, and the upper surface of the product is separated from the bottom surface of the front mold core 4. The piston rod of the injection molding machine pushes the push rod 25 to move upwards, the push rod 25 enables the lower surface of the product to be separated from the upper surface of the rear mold core 17 through the ejector rod 22, and the product is collected by workers after being demolded.
The above detailed description merely describes the preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the design concept and spirit scope of the present invention, the ordinary skilled in the art should belong to the protection scope of the present invention according to the present invention provides the text description and drawings to the various modifications, replacements and improvements made by the technical solution of the present invention. The scope of protection of the present invention is determined by the claims.
