Abstract

The utility model discloses a two-step ejecting mould structure, which comprises a soleplate, coupling screws, a support plate, a lower push plate, an upper push plate, an oscillating bar, a limiting nut, a push rod, a lower template, an upper template, a guide rod, a locating pin, a connecting rod and the like. The soleplate, the support plate and the lower template of the mould are integrated as a whole by the coupling screws; the upper and lower push plates are respectively connected with corresponding push rods by pins; the guide rod is fixed on the lower push plate; the guide rod and the push rod fixed to the lower push plate both pass through the upper push plate; the push rod fixed on the lower push plate is provided with limiting nuts for the upper and lower push rods to fall off together after passing through the upper push plate; the oscillating bar arranged on the lower push plate finishes mutual push motion of the upper push plate; the oscillating bar is out of contact with the upper push plate at the end of location of the upper push plate but continues to move forwards in a containing groove of the support plate so as to finish two-step ejection of the injection-moulded parts by the lower push plate and the push rod thereof. The moulds on the injection-moulded parts are matched with the lower mould by a locating pin sleeve, and the support plate is provided with a locating mechanism for limiting the motion position of the upper push plate.

Description

A kind of secondary is released mould structure

Technical field

The utility model relates to a kind of injection mould and goes out mode structure, belongs to mechanical driving device, is mainly used in the continuous depanning of secondary of moulding.

Background technology

In the production mould structure of moulding; Plastic mostly adopts an ejecting mechanism that moulding is released mold cavity after being shaped, because the requirement of injection moulding; Pushing piece can not be done very greatly, once releases the method for moulding and in push, the plastic pushing is out of shape or damage easily.Bigger for asymmetrical shaped piece influence especially.

Summary of the invention

For the better moulding of realizing does not produce distortion and damages in going out mold process, the utility model provide a kind of simple in structure, be easy to make, the frame for movement of handiness, this frame for movement can realize that the secondary of moulding releases function.

The technical scheme of the utility model is: a kind of secondary is released mould structure, comprises base plate, joint bolt, a seat board, push pedal down, stop nut, upward push pedal, fork, push rod, lower bolster, cope match-plate pattern, guide post, alignment pin, extension bar etc.The base plate of said mould, a seat board and lower bolster are in aggregates with the joint bolt combination; Push pedal links with pin with corresponding push rod separately respectively up and down; Guide post is fixed with following push pedal, and guide post all passes push pedal with the push rod that is fixed in the push pedal down, forms the common direction of motion; Fixing push rod common stop nut that falls after rise of lower push-rod on the Position Design of push pedal has on passing in the following push pedal, following push pedal are provided with the control spacing fork that advances jointly of push pedal up and down, on a seat board, are designed with the detent mechanism of push pedal movement position.

During use; Push pedal drive push rod is separately released moulding integral body from mould along the track that guide post limits up and down, after the depanning of moulding main part, and the stop motion under the detent mechanism effect of last push pedal and push rod; Following push pedal and push rod move on and release the local depanning of moulding; At this moment, the hinge fulcrum of fork in following push pedal that is arranged at down in the push pedal produces sideshake, and the pin of swing link end part setting moves along a seat board upper containing groove; Fork produces with the contacted inclined-plane of last push pedal and separates before, realizes that push pedal down and push rod continue the release moulding and go up push pedal and push rod stop motion.When push rod resetted, following push pedal and push rod fell after rise in advance, and the swing link end part pin skids off along a seat board tank inclined-plane, and the swing link end part inclined-plane contacts with last push pedal inclined-plane, and last push pedal and push rod be common falling the after rise under following push pedal and the effect of push rod upper limit nut thereof.The exact position is realized by the detent mechanism on the seat board.

Secondary described in the utility model is released mould structure and is comprised push pedal and push rod, following push pedal and push rod thereof; The common once release function of accomplishing moulding; And when last push pedal and push rod is limited stop after, following push pedal and push rod thereof the local secondary of accomplishing moulding that moves on is released function.The described fork that is arranged at down in the push pedal accomplish to be gone up the common ahead running of push pedal, and fork breaks away from when last push pedal stops to locate with contacting of last push pedal and in the tank that props up seat board, moves on.Described guide post can be two distributions of symmetry on being provided with.Described moulding mold matches with bed die through set pin sleeve.

It is simple that this secondary is released mould structure, is easy to make, easy to use, realizes the secondary depanning function of special-shaped moulding preferably.

Description of drawings

Accompanying drawing is the cross-sectional view of the utility model.

The specific embodiment

Referring to accompanying drawing; The utility model provides a kind of secondary to release mould structure, comprises base plate 1, joint bolt 2, joint bolt 9, a seat board 3, a seat board 13, push pedal 4 down, hinge 5, stop nut 8, goes up push pedal 17, fork 6, push rod 7, push rod 15, lower bolster 10, cope match-plate pattern 11, guide post 14, alignment pin 12, extension bar 18.

The push rod 7 that said secondary is released mould structure is fixed in the push pedal 4 down, push rod 15 is fixed in the push pedal 17; The guide post 14 that is fixed in the down push pedal 4 can move in the pilot hole of last push pedal and bed die, and the pilot hole that push rod 7 passes on it when last push pedal stop motion can move on.

Base plate 1, a seat board 3, a seat board 13, lower bolster 10 that said secondary is released mould structure fix through joint bolt 2 and joint bolt 9.Fork 6 is bearing in down in the push pedal through hinge 5, and the tank that is provided with on the seat board 3 can whole beat after the swing link end part pin slips into the inclined-plane tank, and fork and last push pedal are disengaged.Be arranged at the position that the detent mechanism on the seat board 13 has limited push rod 7, push rod 15 depannings and answer.

The inclined-plane that said secondary is released the last push pedal 17 of mould structure contacts with fork 6 end chamfer; Locating slot in the last push pedal 17 and the detent mechanism Elastic Contact of propping up on the seat board 13; Be connected with push rod 7 and guide post 14 in the push pedal 4 down, following push pedal 4 is being connected with fork 6 with seat board 3 sides adjacent through hinged support.

The pin that said secondary is released fork 6 ends of mould structure in following push pedal 4 slides along seat board 3 surface; The pin of fork 6 ends falls into the tank of a seat board 3 when last push pedal 17 location, and fork 6 separates with last push pedal 17.
