Abstract
The utility model discloses a novel rapid change ejector and relates to the technical field of casting machine die design. The rapid change ejector comprises a die, an ejector rod and a double-piston-rod oil cylinder, wherein an ejector is fixedly connected to the die, and a locating pin is arranged on the ejector; the ejector rod is fixedly connected with an ejector plate, a pin hole corresponding to the locating pin is formed in the ejector plate, a clamping plate is arranged on the ejector plate, and a locking hole corresponding to the locating pin is formed in the clamping plate; the double-piston-rod oil cylinder is arranged on the ejector plate and used for driving the clamping plate to slide up and down. Through the matching of the clamping plate and the locating pin, the die is rapidly and efficiently changed, and the labor intensity of workers is reduced.
Description
Technical field
The utility model relates to casting machine die design field, particularly a kind of novel quick change liftout attachment.
Background technology
Mould is the main tool in Die Casting, therefore in the time of designing mould, should be noted that to make the general structure of mould rationally safe and reliable as far as possible, be convenient to manufacture and produce, ordinary circumstance lower push rod Length Ratio is longer, the existing pin-lift arrangement that changes generally adopts push rod to be threaded, artificial replacing, or semi-automatic replacing, efficiency is not high.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is how to make ejector pin of die set device change easily and fast.
(2) technical scheme
In order to address the above problem, the utility model provides a kind of novel quick change liftout attachment, and described quick change liftout attachment comprises:
Mould, described mould is fixedly connected with liftout attachment, and described liftout attachment is provided with alignment pin;
Knock-pin, described knock-pin is fixedly connected with top board, and described top board is provided with the pin-and-hole corresponding with described alignment pin, and described top board is provided with clamping plate, and described clamping plate is provided with the locking hole corresponding with described alignment pin;
Double rod cylinder, it is located on described top board, for driving described clamping plate to slide up and down.
Further, in the middle of described clamping plate, be provided with oil cylinder socket, described double rod cylinder is located in described oil cylinder socket, and the piston rod end of described double rod cylinder and the inwall of described socket offset.
Further, described locking hole be " Pear-Shaped ", it comprises macropore and aperture.
(3) beneficial effect
The utility model is by the cooperation of clamping plate and alignment pin, and fast, efficient, ground is mold exchange more, alleviates workman's labour intensity.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the schematic diagram of the utility model in locking state;
Fig. 3 is the schematic diagram of the utility model in releasing orientation;
Fig. 4 is the structural representation of clamping plate in Fig. 3 or Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1～4, described quick change liftout attachment comprises:
Knock-pin 3, described knock-pin 3 is fixedly connected with top board 4, and described top board 4 is provided with the pin-and-hole 40 corresponding with described alignment pin 20, and described top board 4 is provided with clamping plate 6, and described clamping plate 6 is provided with the locking hole 60 corresponding with described alignment pin 20;
Preferably, in the middle of described clamping plate 6, be provided with oil cylinder socket 61, described double rod cylinder 5 is located in described oil cylinder socket 61, the inwall of the piston rod end of described double rod cylinder 5 and described socket 61 offsets, the piston rod of double rod cylinder 5 contacts with 6 of clamping plates, do not adopt rigid connection, self-correcting performance is good.
Preferably, described locking hole 60 be " Pear-Shaped ", it comprises macropore 602 and aperture 601.
As shown in Figure 3, in the time of releasing orientation: the piston rod of double rod cylinder 5 drives clamping plate 6 to move upward, while waiting the macropore 602 of locking hole 60 to aim at the pin-and-hole 40 of top board 4, be releasing orientation, alignment pin 20 can be extracted or insert.
As shown in Figure 2, in the time of locking state: alignment pin 20 is through the macropore 602 of pin-and-hole 40 and clamping plate 6, the piston rod of double rod cylinder 5 drives clamping plate 6 to move downward, the aperture 601 of locking hole 60 is facing to pin-and-hole 40, be now locking state, move downward generation self-locking because gravity can make clamping plate 6 in addition.
Above embodiment is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
