Description

Forming mold for telecommunication box

technical field

The utility model relates to the field of injection molds, in particular to a molding mold for a telecommunication box.

Background technique

Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity, and after cooling and solidifying, a molded product is obtained. Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molds are generally composed of a moving mold and a fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and the fixed mold are separated to take out the plastic product when the mold is opened.

Although the structure of the mold varies according to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same, that is, it is mainly composed of the pouring system, molding parts, exhaust system, temperature control system and Ejection system composition. Among them, the gating system and molding parts are the parts that are in direct contact with the plastic, and change with the plastic and the product. They are the most complex and changing parts in the mold, and require the highest processing finish and precision; the gating system refers to the plastic entering the mold from the nozzle. The part of the runner in front of the cavity, including the main runner, cold slug cavity, runner and gate, etc. Molded parts refer to various parts that make up the shape of the product, including moving molds, fixed molds and cavities, cores, molding rods, and exhaust ports.

As shown in Figure 1, the product must be ejected from the mold of the telecommunication box first by ejecting the injection head 4, and the injection head 4 is located directly below the injection channel 44. The plastic head 4 and the injection plastic head 4 will inevitably collide with the injection runner 44, resulting in the destruction of the mold structure.

Contents of the invention

The technical problem to be solved by the utility model is to provide a mold for forming a telecommunication box. The mold can solve the problem of positional conflict between the injection head and the injection flow channel when the mold is opened through a mechanism.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a mold for forming a telecommunication box, including a movable mold and a fixed mold, the product cavity is formed when the movable mold and the fixed mold are combined, An ejector rod assembly and a slide block assembly are provided, the slide block assembly includes a slide block on which an injection plastic head is placed, and an oblique guide post for driving the slide block to translate to the right is arranged on the slide block, and the ejector rod The assembly includes a material head ejector rod, the upper end of the material head ejector rod passes through the slider and is opposed to the injection molding head, and an upwardly ejected core is arranged in the material head ejector rod;

The slider is driven to translate to the right by the inclined guide post, the injection head placed on the slider, and the material head ejector rod passing through the slider are taken out by the slider at the same time, and the injection head is finally set on the The core in the material head ejector rod is pushed out upwards.

As a further improvement of the utility model, the ejector rod assembly further includes a ejector rod slide seat, a slideway is arranged in the ejector rod slide seat, and the lower part of the ejector rod of the material head is arranged in the slideway and can slide in the slideway .

As a further improvement of the utility model, the fixed mold is provided with a sprue sleeve.

As a further improvement of the utility model, a direction guide column is arranged between the movable mold and the fixed mold.

As a further improvement of the utility model, a locking mechanism is provided between the movable mold and the fixed mold.

Compared with the prior art, the utility model has the advantage that the plastic injection head can be ejected smoothly without colliding with the injection flow channel. After the plastic injection head is moved out laterally by using the slider, the plastic injection head can be pushed out by the ejector pin. The collision between the injection runner and the injection plastic head is avoided when the mold is opened. Specifically, the mold includes a movable mold and a fixed mold, and the structure is simple. An inclined guide column connected with the movable mold is set on the slider on which the injection head is placed. When the movable mold falls vertically, the inclined guide column can drive The slider moves to the right, and at the same time, the material head ejector rod passing through the slider also moves to the right along with the slider. Since the injection plastic head and the material head ejector rod are offset, when the slider moves to the right for a certain distance, the material head top The core in the rod pushes out the injection molding head.
