Description

An external pull rod type drive push plate mold

technical field

The utility model belongs to the field of moulds, and in particular relates to a mould, which has a simple structure and is driven by an external pull rod type push plate.

Background technique

Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material, known as the "mother of industry".

At present, the known injection molding and metal die-casting molds all use push rods, push blocks, pneumatic, electric, hydraulic pressure, and at the same time have to design ejection plates and ejection backing plates, so far resulting in complex mold structures. Manufacturing, Installation and maintenance are inconvenient, and mold consumables are large, resulting in high mold costs.

Contents of the invention

The utility model aims at the above deficiencies, and proposes an outer pull rod-type driven push plate mold with relatively precise control of the push-out stroke. The mold eliminates ejector pins, springs, etc., and has a simple structure, convenient installation and maintenance, and low cost.

The technical scheme adopted in the utility model is:

A kind of push plate mould, driven by an external pull rod, comprising an upper die, a lower die, an upper die, a lower die, and a guide post. The mold and the lower mold are movable, and the upper mold and the lower mold are provided with mold cavities, and the upper mold is provided with a feed port, which is connected to the mold cavity, and a push plate is connected to the upper die, and the two push plates The side is connected with an outer pull rod, and the push plate is installed on the guide post and can slide up and down along the guide post.

Preferably, the feed inlet is semi-open.

The beneficial effects of the utility model are:

The structure is simple, the operation is convenient, the mold consumables are small, the mold cost is low, and it is easy to be popularized.

Among the figure 1, upper mold, 2, lower mold, 3, upper template, 4, lower template, 5, guide post, 6, feed inlet, 7, mold cavity, 8, push plate, 9, outer tie rod.

detailed description:

The utility model is described further in conjunction with accompanying drawing now.

As shown in the accompanying drawings, an external pull rod type push plate mold includes an upper mold 1, a lower mold 2, an upper mold 3, a lower mold 4, and a guide post 5. The upper mold 1 is installed on the upper mold 3, and the lower mold 2 Set on the lower template 4, guide pillars 5 are installed on the lower mold 2, the upper mold 1 and the lower mold 2 are movable, the upper mold 1 and the lower mold 2 are provided with a mold cavity 7, and the upper template 3 is provided with a The feed port 6 and the feed port 6 are connected to the mold cavity 7, and the upper mold 1 is connected with a push plate 8, and the two sides of the push plate 8 are connected with outer pull rods 9, and the push plate 8 is installed on the guide post 5 and can be moved along the guide post. Swipe up and down.

The feeding port 6 is a semi-open type, and it will not be drawn when the finished product is finished.

When demolding, just pull the outer pull rods 9 on both sides, and the push plate 8 will be lifted along the guide post 5, pushing the upper mold 1 to move upwards, and the finished product will slowly break away from the upper mold 1 due to its own gravity.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any skilled person familiar with the art can easily think of changes within the technical scope disclosed in the utility model Or replacement, all should be covered within the scope of protection of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
