Abstract

The utility model provides a simple secondary ejection structure, which comprises a first ejector pin and a second ejector pin, wherein the first ejector pin is arranged on an ejector pin plate. The simple secondary ejection structure is characterized in that the top of the ejector pin plate is provided with a stop block; an insert block is arranged in the stop block; the bottom of the second ejector pin is fixed on the insert block; the insert block is provided with spacer pins; the top ends of the spacer pins are arranged outside the ejector pin plate; the insert block is arranged on a bearer; and the bearer is connected with a spring. The simple secondary ejection structure has the advantages that the mould thickness can be reduced and has a simple structure and low cost.

Description

A kind of simple secondary ejecting structure
Technical field
The utility model relates to a kind of novel secondary ejecting structure, is applicable to that indivedual thimbles withstand on the mould on the product rib, belong to the injection moulding apparatus technical field.
Background technology
The plastic product of some injection mouldings; because the structural limitations of product; indivedual thimbles must come on the rib of product (rib is deep); usually can use 4 plate ejector retainner plates; as shown in Figure 1; be traditional secondary ejecting structure schematic diagram, formed by upper mounted plate 1, solid plate 2, moving platen 3, mould pin 4, first ejector retainner plate 5, second ejector retainner plate 6, the 3rd ejector retainner plate 7, the 4th ejector retainner plate 8, bottom plate 9, product 10, die 11, first thimble 12 and second thimble 13.For product is come off automatically, so will do the secondary ejecting structure.In order to do the secondary ejecting structure, just added two ejector retainner plates, increased the thickness of mould like this, the moulding board is selected in influence, has improved die cost simultaneously.
Summary of the invention
The purpose of this utility model provides the reduction mold thickness, and processing is simple, lower-cost secondary ejecting structure.
In order to achieve the above object, the technical solution of the utility model has provided a kind of simple secondary ejecting structure, comprise first thimble and second thimble, first thimble is located on the ejector retainner plate, it is characterized in that: the top at ejector retainner plate is provided with limited block, the mold insert piece is located in the limited block, the bottom of second thimble is fixed on the mold insert piece, is provided with spacer pin on the mold insert piece, and the top of spacer pin is located at outside the ejector retainner plate, the mold insert piece is located on the tray, and tray links to each other with spring.
Further, be provided with fixed block in the bottom of described ejector retainner plate, described spring is located in fixed block and the ejector retainner plate.
The utility model has the advantages that: can reduce mold thickness, simple in structure, with low cost.
Description of drawings
Fig. 1 is traditional secondary ejecting structure schematic diagram;
The simple secondary ejecting structure schematic diagram that Fig. 2 provides for the utility model.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 2, a kind of simple secondary ejecting structure that provides for the utility model, comprise that first thimble 14 and second thimble, 15, the first thimbles 14 are located on the ejector retainner plate 16, be provided with limited block 17 at the top of ejector retainner plate 16, mold insert piece 18 is located in the limited block 17, the bottom of second thimble 15 is fixed on the mold insert piece 18, is provided with spacer pin 19 on mold insert piece 18, and the top of spacer pin 19 is located at outside the ejector retainner plate 16, mold insert piece 18 is located on the tray 22, and tray 22 links to each other with spring 20.Be provided with fixed block 21 in the bottom of ejector retainner plate 16, spring 20 is located in fixed block 21 and the ejector retainner plate 16.
When mould ejected, ejector retainner plate 16 drove first thimble 14, second thimble 15, limited block 17, spacer pin 19, mold insert piece 18, tray 22, spring 20 and fixed block 21 and moves together.When spacer pin 19 was run into moving platen, spacer pin 19 began to compress spring 20 with mold insert piece 18 and tray 22, makes 15 stop motions of second thimble, and ejector retainner plate 16 is also moving, thereby reaches the purpose that secondary ejects.
