Description

Simplified secondary ejection structure

Technical Field

The utility model relates to a plastic mould technical field, concretely relates to ejecting structure of secondary who simplifies.

Background

The traditional secondary ejection mode has the following technical defects and shortcomings: 1. 2 groups of ejector pin plates are needed, the thickness of the die is thicker than that of a normal die, the processing cost is increased, and the installation is troublesome; 2. due to the increase of the thickness, a plurality of molds need to be enlarged for the production of a first injection molding machine, so that the cost of the machine is wasted; 3. two groups of ejector pin plates are ejected, secondary ejection standard parts or buckling machines are required to be added, and cost is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a two-shot ejection structure of simplifying.

The technical scheme of the utility model as follows:

a simplified double ejection structure, comprising:

the first ejection mechanism consists of an ejector rod, a small ejector plate and a small ejector pin, the second ejection mechanism consists of a large ejector plate and an ejector pin, a movable key is arranged in the large ejector plate, and a groove is formed in the ejector rod corresponding to the position of the movable key so as to be matched with the movable key.

The utility model discloses in, the inside yellow spring that is equipped with of feather key, yellow spring and a stop device cooperation, according to in order to guarantee the feather key with the ejector pin contact.

The utility model discloses in, ejector pin middle part one side is equipped with a navigation key.

The utility model discloses in, big thimble board is connected with external drive arrangement, and by the drive arrangement drive.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the utility model discloses a big thimble board drives the thimble and drives ejector pin and little thimble through the movable key simultaneously and ejecting with the product, and rethread movable key makes the movable key rebound with stop device separation cooperation yellow spring, makes the ejector pin lose power, only drives the thimble through big thimble board and further ejecting to the product, and whole action is simple, only needs a set of thimble board reduction in production cost, reduces the use of secondary top standard component or fastener, the risk that probably appears when avoiding ejecting.

Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical solution of the present invention, the following description is made by using specific examples.

Examples

Referring to fig. 1 to 3, the present invention provides a simplified secondary ejection structure, including:

the ejector pin comprises a first ejector mechanism and a second ejector mechanism, wherein the first ejector mechanism consists of an ejector pin 1, a small ejector pin plate 2 and a small ejector pin 3, the second ejector mechanism consists of a large ejector pin plate 4 and an ejector pin 5, a movable key 6 is arranged in the large ejector pin plate 4, and a groove 11 is formed in the ejector pin 1 corresponding to the position of the movable key 6 and matched with the movable key 6. The ejector pins 5 are driven by the large ejector pin plate 4, the ejector pins 1 are driven by the cooperation of the movable keys 6 and the grooves 11, the small ejector pin plate 2 and the small ejector pins 3 are driven by the ejector pins 1, the product 9 is ejected synchronously, and the ejection for the first time is completed.

In this embodiment, a yellow spring 61 is disposed inside the movable key 6, and the yellow spring 61 cooperates with a limiting device 7 to ensure that the movable key 6 contacts with the push rod 1. Before the first ejection action is finished, the limiting device 7 and the yellow spring 61 cannot rebound, so that the movable key 6 is always clamped with the groove 11 to drive the ejector rod 1 to move, after the first ejection action is finished, the limiting device 7 is separated from the yellow spring 61 at the same time, the yellow spring 61 rebounds and drives the movable key 6 to move to be separated from the clamping groove 11, the ejector rod 1 loses power, and the large ejector plate 4 only drives the ejector pin 5 to further eject the product 9, so that the second ejection action is finished.

In this embodiment, a positioning key 8 is arranged on one side of the middle part of the top rod 1. The movement distance of the mandril 1 can be effectively ensured.

In the present embodiment, the large ejector plate 4 is connected to and driven by an external drive.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
