Description

A secondary ejection mechanism for door panel horn mesh

technical field

The invention belongs to the field of injection molds, in particular to a secondary ejection mechanism for the horn mesh of a door panel.

Background technique

In the process of plastic mold design, especially the front and rear door panels of automobiles, it is often seen that there are speaker mesh designs on the door panels. Because the speaker mesh is small, the required thimble is also small. In this case, a longer thimble is required, which will inevitably cause the thimble to be affected by bending deformation. Therefore, it is necessary to find a kind of ejection mechanism that can not only satisfy the demoulding of the horn mesh, but also make the strength of the thimble pin unaffected.

Utility model content

In view of the above technical difficulties, the purpose of the present invention is to provide a secondary ejection mechanism that can satisfy the ejection of the horn mesh without affecting the strength of the ejector pin.

Above-mentioned purpose realizes through following technical scheme:

A secondary ejection mechanism for the horn mesh of the door panel, characterized in that it includes a horn mesh thimble panel and a horn mesh thimble bottom plate, the two are fixed together by screws, and multiple thimbles are fixed on the horn mesh On the thimble panel, the horn mesh backing plate is fixed on the core plate to prevent it from falling; the bottom end of the horn mesh reset rod is connected to the thimble plate at the lower end, and the top of the horn mesh reset rod passes through the horn mesh backing plate and The speaker mesh thimble bottom plate is fixed on the horn mesh thimble panel; the guide mechanism is fixed on the horn mesh thimble backing plate, which guides the horn mesh thimble panel and the horn mesh thimble bottom plate; the nitrogen spring is installed on the horn mesh thimble The bottom plate and the horn mesh thimble backing plate are provided with ejection limit blocks on the surface of the horn mesh thimble panel 1 .

Further, the horn mesh thimble panel and the horn mesh thimble bottom plate are defined in the ejection cavity between the two by the horn mesh thimble backing plate and the core plate, the horn mesh thimble panel and the core There is an ejection space between the plates.

Further, the thimble plate is composed of a thimble panel and a thimble bottom plate, the top of the horn mesh reset rod is fixed on the horn mesh thimble panel through the horn mesh backing plate and the horn mesh thimble bottom plate, and the horn mesh reset pull rod The bottom end passes through the thimble panel and the thimble bottom plate and is provided with a nut at the end.

Further, the lower end of the ejection limit block is fixed on the horn mesh thimble panel, and the upper end is horn-shaped.

The secondary ejection mechanism with the above structure has the following advantages:

1. The secondary ejection mechanism of the horn mesh simplifies the space structure of the mold, greatly reduces the production cost, and at the same time facilitates maintenance and repairs to ensure high precision.

2. One power output completes the ejection process of the two mechanisms, which improves the efficiency and makes the ejection process smooth and smooth.

3. The design concept of the secondary ejection mechanism of the horn mesh breaks the conventional thinking mode of secondary ejection, expands the application range of the ejection mechanism, and has novel and innovative significance and broad market application prospects.

detailed description

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, a secondary ejection mechanism for the horn mesh of the door panel includes a horn mesh thimble panel 1 and a horn mesh thimble bottom plate 2, the two are fixed together by screws, and multiple The thimble 9 is fixed on the thimble panel 1 of the speaker mesh, the backing plate 3 of the speaker mesh is fixed on the core plate 10 to prevent it from falling, and the bottom ends of the two speaker mesh reset rods 6 are connected to the thimble plate 11 at the lower end, The top of the horn mesh reset rod 6 is fixed on the horn mesh thimble panel 1 through the horn mesh backing plate 3 and the horn mesh thimble bottom plate 2; the guide mechanism 5 is fixed on the horn mesh thimble backing plate 3, and The thimble panel 1 and the horn mesh thimble bottom plate 2 play a guiding role; the nitrogen spring 4 is installed on the horn mesh thimble bottom plate 2 and the horn mesh thimble backing plate 3, and an ejection limit is set on the surface of the horn mesh thimble panel 1 Block 8. The lower end of the ejection limit block 8 is fixed on the horn mesh thimble panel 1, and the upper end is horn-shaped.

As shown in FIG. 2 , in the mold closing state, the horn mesh thimble panel 1 and the horn mesh thimble bottom plate 2 are defined by the horn mesh thimble backing plate 3 and the core plate 10 at the top between the two. In the cavity 20 , there is an ejection distance between the speaker mesh thimble panel 1 and the core plate 10 . The thimble plate 11 is composed of a thimble panel 111 and a thimble bottom plate 112. The top of the horn mesh reset rod 6 is fixed on the horn mesh thimble panel 1 through the horn mesh backing plate 3 and the horn mesh thimble bottom plate 2. The horn mesh The bottom end of the hole reset pull rod 6 passes through the thimble panel 111 and the thimble bottom plate 112 and the end surface of the horn mesh reset pull rod (6) is provided with a nut 61 .

As shown in Figure 3, when the product is being ejected, the ejector plate 111 and the ejector bottom plate 112 of the ejector plate 11 start to eject the ejection signal of the injection molding machine. Mesh thimble bottom plate 2 provides thrust. When the ejection limit block 8 touches the top of the core plate 10, the speaker mesh thimble panel 1 and the speaker mesh thimble bottom plate 2 are no longer ejected, and the first ejection movement is completed. Next, the ejector plate 111 and the ejector bottom plate 112 of the ejector plate 11 continue to be ejected to complete the second ejection of the product. After the parts are picked up, the thimble panel and the thimble bottom plate of the thimble plate 11 are reset under the reset signal of the injection molding machine. At this time, the horn mesh thimble panel 1 and the horn mesh thimble bottom plate 2 are not reset under the action of the nitrogen spring 4. Wait until the thimble panel and the thimble bottom plate of the thimble plate 11 are reset and touch the reset pull rod 6 of the horn mesh, the thimble 9 of the horn mesh and the thimble plate 11 of the horn mesh start to reset, and the nitrogen spring 4 is compressed and returned to Clamping state.

The secondary ejection mechanism of the present invention uses the nitrogen spring 4 as power. When the mold is opened to eject the product, the horn mesh thimble panel and the horn mesh thimble bottom plate complete the ejection of the horn mesh under the action of the nitrogen spring. After stopping, the product will continue to be ejected along with the motion of the ejector plate 11, completing the second ejection action of the entire product. This structure makes good use of the ejection process of the mold to control the ejection distance of the horn mesh, and the ejection process is a stable and safe feasible mechanism.

The above is only a preferred embodiment of the present invention, and any simple modification, equivalent change or modification made to the above principles according to the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
