Description
Technical field
The utility model relates to injection mold field, particularly a kind of mold in turn ejecting mechanism.
Background technology
Injection mo(u)lding refers to, the material that melts that is heated is injected die cavity by high pressure, after cooling curing, obtains the method for formed products.The method is applicable to the batch production of complex-shaped parts, is one of important processing method.The action that ejects of ordinary circumstance bed die is all one step completed, but when the shape of product the special or demand during according to volume production, need carry out repeatedly sequentially ejecting.Specifically refer to install in the mould side sequencing mechanism, utilize the principle that ejects of injector, mould dynamic model side is formed repeatedly eject, thereby complete mould a series of actions, guarantee that product is not damaged, and causes the defective on product when avoiding ejecting when the demoulding.Often encountering in die design process first needs B plate and backing plate somatotype, then carries out dynamic model side Double-ejection, and in the past mostly is to need two nested structures to realize, safety and reliability directly affect formed in mould cost and efficient nearly less than requiring.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of structure comparatively simple, safe and reliable mold in turn ejecting mechanism.
the technical scheme in the invention for solving the above technical problem is: a kind of mold in turn ejecting mechanism, the jacking block that comprises the sidewall that is fixedly connected on the B plate, be fixedly connected on the sidewall of backing plate and be sleeved on the outer tapered wedges of described jacking block, slide block, at least one spring and be fixedly connected on the second Ejector Retainer Plate and be used for supporting the back-up block of described slide block, described slide block is slidably tied in the cavity of the first Ejector Retainer Plate, and an end of described spring is butted on described slide block, the other end of described spring is butted on the inwall of described the first Ejector Retainer Plate, described slide block is provided with the inclined plane, the bottom of the sidewall of described tapered wedges and middle part are provided with successively for the first inclined-plane that matches with the inclined plane of described slide block and the second inclined-plane.
Compared with prior art, the utility model has the advantage of: this mold in turn ejecting mechanism utilizes a simple structure of cover can realize that three orders eject, namely by slide block in ejection process respectively with the first inclined-plane of the contact-making surface of jacking block, tapered wedges, the coordinating of the second inclined-plane of tapered wedges realize that three orders eject, durability better, more safe and reliable.
As improvement, it also comprises protective sleeve, and described protective sleeve is sleeved on the outside of described back-up block and tapered wedges, and described protective sleeve is fixedly connected on the sidewall of the first thimble fixed head and the first Ejector Retainer Plate.Can play the effect of protection like this.
As further improvement, offer the blind hole for an end of accommodating described spring on described slide block, offer the groove for the other end of accommodating described spring on the correspondence position of described the first Ejector Retainer Plate.Like this, the motion of spring is more steady, better reliability.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
as shown in Fig. 1-4, a kind of mold in turn ejecting mechanism, the jacking block 1 that comprises the sidewall that is fixedly connected on B plate 7, be fixedly connected on the sidewall of backing plate 8 and be sleeved on the outer tapered wedges 2 of described jacking block, slide block 4, at least one spring 6 and be fixedly connected on the second Ejector Retainer Plate 12 and be used for supporting the back-up block 5 of described slide block, described slide block 4 is slidably tied in the cavity of the first Ejector Retainer Plate 10, and an end of described spring 6 is butted on described slide block 4, the other end of described spring 6 is butted on the inwall of described the first Ejector Retainer Plate 10, described slide block 4 is provided with inclined plane 4.1, the bottom of the sidewall of described tapered wedges 2 and middle part are provided with successively for the first oblique 2.1 and the second inclined-plane 2.2 that matches with the inclined plane 4.1 of described slide block 4.
It also comprises protective sleeve 3, and described protective sleeve 3 is sleeved on the outside of described back-up block 5 and tapered wedges 2, and described protective sleeve 3 is fixedly connected on the sidewall of the first thimble fixed head 9 and the first Ejector Retainer Plate 10.
Offer the blind hole for an end of accommodating described spring 6 on described slide block 4, offer the groove for the other end of accommodating described spring 6 on the correspondence position of described the first Ejector Retainer Plate 10.
Operation principle of the present utility model is: after injection machine injection moulding die sinking, owing at jacking block 1 and slide block 4, a contact-making surface being arranged, realize ejecting for the first time (as shown in Figure 2) by this face when ejecting.When ejecting certain distance L 1, slide block 4 touches the first inclined-plane 2.1 of tapered wedges 2, under the inclined-plane squeezing action, makes slide block 4 and spring 6 carry out primary compression rollback, realize the disengaging of jacking block 1 and slide block 4 contact planes, but also contact (as shown in Figure 2) with back-up block 5.Eject for the second time, when ejecting distance L 2, slide block 4 touches the second inclined-plane 2.2 of tapered wedges 2 again, under the inclined-plane squeezing action, make slide block 4 and spring 6 carry out again secondary compression rollback, realize the disengaging of back-up block 5 and slide block 4 contact planes, thereby realize secondary top (as shown in Figure 3).When ejecting for the third time, all mechanism's parts are rollback all, when ejecting distance L 3, contacts with Ejector Retainer Plate 1, thereby realizes three tops (as shown in Figure 4).
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in the utility model protection domain.
