It closes.
By said program as it can be seen that in the present invention, first using the first mold dynamic model mating mold cover half to product
Carry out the injection molding of the first material, reuse after the completion the second mold dynamic model mating mold cover half product topmost
Carry out the covering injection molding of second of material, wherein since product has hole slot, need using slide structure cooperation inclined guide pillar
It can be molded, in matched moulds stage, inclined guide pillar is inserted into oblique straight slot, since the place of the lower contacts of pin and inclined guide pillar is equal
For arc-shaped, so pin is got by inclined guide pillar in pin hole, so slide structure will not integrally be moved, in addition, in molding latter stage,
Pin is popped up due to the relationship of the oblique unfilled corner on inclined guide pillar and is stuck at the top of oblique unfilled corner；When in die sinking stage, inclined guide pillar
It pulls out upwards, pin heads on the side wall of oblique unfilled corner so that inclined guide pillar pushes the drive of entire slide structure aside in upper pull out so that injection molding
The product finished can be removed.The utility model coordinates the movement of oblique straight slot progress line position, precision high using inclined guide pillar.
Further, several cavities compatible with product are provided on the mode, if the slide structure further includes
Slide block corresponding with the cavity is done, several slide blocks are fixedly connected with the line position main body, the slide block
It is matched with product, convex block corresponding with the groove on product is provided in the slide block.
By said program as it can be seen that in the present invention, driving multiple slide blocks to carry out simultaneously using one piece of line position main body
Simultaneously operating improves injection efficiency.
Further, ramp structure is provided on the outside of the line position main body, the shovel base matches with the ramp structure
It closes, the front and rear sides of the line position main body are both provided with cross slide way, and the cross slide way is matched with stationary mould for mould.
By said program as it can be seen that in the present invention, design shovel base is used to that slide block to be inserted into cavity at the beginning,
It waits for and is molded the first material, the i.e. molding of product bed die.
Further, the upper end of the inclined guide pillar is fixedly connected with push-and-pull block, and the push-and-pull block is fixed with mold dynamic model to be connected
It connects.
By said program as it can be seen that in the present invention, inclined guide pillar is connected by pushing and pulling block with mold dynamic model simultaneously same
Step movement.
