Abstract
The utility model discloses an ejection structure free of an ejection pin. The ejection structure comprises an A plate, a front inner mould, a shovel base, a line position, a demoulding plate, an elastic plate, a back inner mould, a cushion plate, an inclined guide column and an equal height screw. A spring is arranged between the elastic plate and the cushion plate. Due to the fact that the spring is arranged between the elastic plate and the cushion plate, the cushion plate and the elastic plate can be separated in bouncing mode under the elasticity of the spring, and a product breaks away from the back inner mould without being ejected by the ejection pin. The surface of the product can be intact without ejection pin impresses, and appearance attractive degree of the product is remarkably improved.
Description
Technical field
The utility model relates to mould applications, relates in particular to a kind of ejecting structure without the thimble seal.
Background technology
Traditional moulds comprises: A plate, front internal mold, shovel base, line position, stripper plate, diving board, rear internal mold, backing plate, Angle Pin, contour screw;
In the mould production process, after the product moulded section, usually can use thimble with mould ejection, allow a mould line position break away from, but tend to make mould the thimble seal to occur, be unfavorable for very much the attractive in appearance of product.
The utility model content
It is a kind of without thimble seal ejecting structure that problem to be solved in the utility model is to provide, and when guaranteeing the product die sinking, without the thimble seal, makes product more attractive in appearance.
For overcoming the above problems, the utility model by the following technical solutions: without center lift-out structure, comprising: A plate, front internal mold, shovel base, line position, stripper plate, diving board, rear internal mold, backing plate, Angle Pin, contour screw; Be provided with spring between described diving board and the backing plate.
Rear internal mold is screwed on the backing plate, and line position is slided at diving board.When mould is opened, under the elastic force effect of spring, flicked internal mold after this moment, product broke away between backing plate and the diving board.When spacing the working of contour screw, under the pulling force of injection machine, begin to open between A plate and the diving board, the product of this moment is bonded on the line position, so product breaks away from the front internal mold on the A plate.When Angle Pin drive line position begins to slide, because product packs tightly on line position, therefore also simultaneously motion, until product contacts with stripper plate, stripper plate follows line position to break away from product in the slip of line position, product drops automatically.
The utility model arranges spring between diving board and backing plate, under the effect of this spring force, flicked between backing plate and the diving board, internal mold after product breaks away from ejects rear internal mold and need not thimble with product, makes product surface complete, and without the thimble seal, significantly improved the aesthetic measure of product.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, Angle Pin; 2, front internal mold; 3, shovel base; 4, line position; 5, stripper plate; 6, diving board; 7, backing plate; 8, product; 9, spring; 10, contour screw; 11, A plate; 12, rear internal mold.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1: without center lift-out structure, comprising: A plate 11, front internal mold 2, shovel base 3, line position 4, stripper plate 5, diving board 6, rear internal mold 12, backing plate 7, Angle Pin 1, contour screw 10; Be provided with spring 9 between described diving board 6 and the backing plate 6.
Rear internal mold 12 is screwed on the backing plate 7, and line position 4 is slided at diving board 6.When mould is opened, under the elastic force effect of spring 9, flicked internal mold 12 after product 8 disengagings this moment between backing plate 7 and the diving board 6.When spacing the working of contour screw 10, under the pulling force of injection machine, begin to open between A plate 11 and the diving board 6, the product 8 of this moment is bonded on the line position 4, so product 8 breaks away from the front internal mold 2 on the A plate 11.When Angle Pin 1 drive line position 4 begins to slide, because product 8 packs tightly on line position 4, therefore also simultaneously motion, until product 8 contacts with stripper plate 5, stripper plate 5 follows line position 4 to break away from product 8 in the slip of line position 4, product 8 drops automatically.
The utility model is not limited to the above-mentioned specific embodiment; the according to the above description announcement of book and guidance; the utility model those skilled in the art also can carry out suitable change and modification to above-mentioned embodiment, and its change also should fall into the protection domain of claim of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
