Abstract

The utility model discloses a secondary ejection device for an injection mould, and the device comprises a substrate (1), wherein the substrate is of a structure which is in the shape of a Chinese character of 'ao'; an oscillating block (2) is arranged in a groove which is in the shape of a Chinese character of 'ao' of the substrate (1); the oscillating block (2) is movably connected to the substrate (1) by a hinge pin (3); and the vertical distance (H) from the center of the hinge pin (3) to two ends of the oscillating block (2) is greater than vertical distance (h) from the center of the hinge pin (3) to the edge of the substrate (1). In the secondary ejection device for the injection mould, the oscillating block structure capable of rotating in the substrate is adopted, the rotation of the oscillating block is used for ejecting a top plate which is ejected out for the second time; and the top plate drives the ejection rod to realize the secondary ejection of the mould. The ejection force which can be transferred by the structure is stable, and the ejection action is reliable, therefore secondary ejection can be quickly and simply realized. According to parameters, such as the size of the mould, demoulding force, secondary ejection distance and the like, standard parts of different specifications can be manufactured for mould production manufacturers so as to lower the mould manufacturing cost and shorten the mould manufacturing period.

Description

Injection mold secondary liftout attachment
Technical field
The utility model relates to a kind of liftout attachment, particularly a kind of injection mold secondary liftout attachment.
Background technology
Many plastic cement products could be accomplished demoulding action because the complexity of structure can not directly be ejected by push rod or ejector sleeve but will eject through secondary after injection mo(u)lding.At present; Secondary liftout attachment used in the injection mold mainly contains several kinds of modes, and they are respectively spring secondary liftout attachments, rely on the secondary of hydraulic cylinder or air cylinder driven to eject, cam secondary liftout attachment, ratchet secondary liftout attachment, slide block secondary liftout attachment etc.The spring secondary ejects, and its advantage is simple in structure, and erection space is little, and shortcoming is to transmit too big power, and spring is prone to lose efficacy, and it is unreliable to move; Several kinds of secondary liftout attachments then, though reliable in action, mechanism is huge, complex structure and since receive mould structure and volume restriction and can not extensive use.
Summary of the invention
The utility model technical problem to be solved is: a kind of injection mold secondary liftout attachment is provided, and it is simple in structure, cost is lower, and reliable in action can guarantee the secondary liftout attachment of the smooth demoulding of plastic product, to overcome the deficiency of prior art.
The utility model be achieved in that injection mold secondary liftout attachment; Comprise pedestal; Pedestal is the concave shape structure; In the concave shape groove of pedestal, be provided with centering block, centering block is movably connected on the pedestal through pivot pin, and the vertical range at the edge of pedestal is arrived at the center of pivot pin greater than the center of pivot pin to the vertical range at the two ends of centering block.
On pedestal, be provided with installing hole.Make things convenient for the installation and removal of pedestal.
Owing to adopted technique scheme; Compared with prior art, the utility model adopts the centering block structure that can in pedestal, rotate, utilizes the rotation of centering block to come jack-up to be used for the top board that secondary ejects; Driving push rod through this top board ejects with the secondary of realizing mould; Reliable in action is stablized, is ejected in the ejecting force that this structure can be transmitted, and therefore can realize simply fast that secondary ejects, and also can eject apart from parameters such as sizes according to size, the size of knockout press, the secondary of mould; The standard component of making different size supplies die production producer to select for use, thereby reduces the Mold Making cost and shorten the Mold Making cycle.The utility model is simple in structure, implements easily, and result of use is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the vertical view of accompanying drawing 1;
Accompanying drawing 3 is the use sketch map of the utility model.
The specific embodiment
The embodiment of the utility model: the structure of injection mold secondary liftout attachment is as shown in Figure 1; The pedestal 1 that comprises the concave shape structure; In the concave shape groove of pedestal 1, be connected with centering block 2 through bearing pin; Centering block 2 can rotate in the concave shape groove of pedestal 1 through pivot pin 3, and the vertical range h at the edge of pedestal 1 is arrived at the center of pivot pin 3 greater than the center of pivot pin 3 to the vertical range H at the two ends of centering block 2; On pedestal 1, be provided with installing hole 13.
In use, pass the installing hole 13 of pedestal 1, pedestal 1 is fixed in the push pedal 5 of injection mold with screw 4.When product carried out the demoulding after injection moulding is accomplished, injection machine push rod 10 pushed push pedal 5 and travels forward, and push pedal 5 whole devices of drive and push rod 11, secondary push rod 12 travel forward, and push rod 11 drives 9 motions of push piece plates, and product is deviate from from core 8; Injection machine push rod 10 continues to push push pedal 5 and travels forward; When the centering block 2 of the utility model is run into the mould pin 6 on the mould; Because centering block 2 receives stopping of mould pin 6; Centering block 2 will rotate and push secondary push pedal 7 around pivot pin 3, and secondary push pedal 7 drives secondary push rods 12 product is ejected push piece plate 9, accomplishes product stripping like this.Matched moulds carries out the injection moulding of following one-period then.

Claims (2)

1. injection mold secondary liftout attachment; Comprise pedestal (1); It is characterized in that: pedestal (1) is the concave shape structure; In the concave shape groove of pedestal (1), be provided with centering block (2), centering block (2) is movably connected on the pedestal (1) through pivot pin (3), and the vertical range (h) at the edge of pedestal (1) is arrived at the center of pivot pin (3) greater than the center of pivot pin (3) to the vertical range (H) at the two ends of centering block (2).
