Description

Insert guide structure

Technical Field

The utility model relates to the field of mold design, in particular to an insert guide structure.

Background

The mold is a tool for manufacturing molded articles, and in order to improve the production efficiency and reduce the pouring loss of a runner, a multi-cavity mold can be adopted, and a plurality of identical or different products can be finished in one mold at the same time. The precise multi-cavity die has the special emphasis that the size of each cavity is the same, and the size of a glue position is unstable easily due to the fact that the hole position of the rear die insert on the die plate is eccentric, and the rear die is easy to scratch.

For this reason, a technical means is needed to solve the above-mentioned drawbacks.

an insert guide structure comprises a rear template, a rear mold core, a guide block and a rear mold insert; the rear mold core is arranged in the rear mold plate; the guide block is arranged on the rear die core, and a guide hole facing the rear die core is formed in the guide block; one end of the rear mold insert is arranged in the rear mold core, and the other end of the rear mold insert is arranged in the guide hole.

Preferably, the device also comprises a limiting block; the limiting block is arranged below the guide block; a limiting hole is formed in the limiting block; one end of the rear mold insert penetrates out of the guide hole and is fixedly arranged in the limiting hole.

Preferably, the whole limiting hole is a T-shaped limiting hole.

Preferably, the device also comprises a bottom plate; the bottom plate is arranged below the rear template; the bottom plate is provided with a first mounting hole; the limiting block is installed in the first installation hole.

Preferably, the rear template is provided with a second mounting hole; the guide block is installed in the second installation hole.

Preferably, the device also comprises a front template; the front template is mounted on the rear template.

According to the insert guide structure, due to the arrangement of the guide block, when the mold is closed, one end of the rear mold insert is arranged in the guide hole of the guide block, so that the condition that the rear mold insert is eccentric due to inaccurate machining is avoided, the rear mold insert and the rear mold insert are protected from being scratched, and the service life of the mold is prolonged.

Detailed Description

The following description of the embodiments of the present utility model will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 to 2, an insert guide structure includes a rear mold plate 10, a rear mold core 20, a guide block 30, and a rear mold insert 40; the rear mold core 20 is arranged in the rear mold plate 10; the guide block 30 is mounted on the rear mold core 20, and a guide hole 301 facing the rear mold core 20 is arranged in the guide block 30; one end of the rear mold insert 40 is installed in the rear mold core 20, and the other end is installed in the guide hole 301.

Specifically, a cavity through hole 201 for installing the rear mold insert 40 is provided in the rear cavity 20, and the cavity through hole 201 is aligned with the guide hole 301; through the setting of guide block 30, during the compound die, because the one end of back mould mold insert 40 is installed in the guiding hole 301 of guide block 30, avoided back mould mold insert 40 to have taken place because of the inaccurate circumstances that causes the decentration of processing, and then protected back mould mold insert 40 and back mould benevolence 20 can not scratch to the life of mould has been improved.

In a specific embodiment, a base plate 50 is also included; the bottom plate 50 is installed below the rear form 10; the bottom plate 50 is provided with a first mounting hole; the stopper 70 is installed in the first installation hole. Further, the rear mold plate 10 is provided with a second mounting hole; the guide block 30 is mounted in the second mounting hole. Further, a front template 60 is included; the front form 60 is mounted to the rear form 10.

In a specific embodiment, a stopper 70 is also included; the limiting block 70 is arranged below the guide block 30; a limiting hole 701 is formed in the limiting block 70; one end of the rear mold insert 40 penetrates the guide hole 301 and is fixedly installed in the limit hole 701. During die opening, the rear die plate 10 is ejected under the action of the ejector rod, and the rear die insert 40 is kept fixed through the limiting block 70, so that a molded finished product on the rear die plate 10 is effectively separated from the rear die insert 40.
