Description

Forming die of lamp shell

Technical Field

The utility model belongs to the technical field of the mould and specifically relates to a forming die of lamp housing is related to.

Background

The injection molding process is a processing method frequently used in mass production of parts with complex shapes, and particularly relates to a method for obtaining a molded product by injecting a molten melt which is heated into a mold cavity and cooling and solidifying the molten melt. The injection mold is a tool for producing plastic products, and can obtain the complete structure and accurate size of the plastic products. The injection mold generally comprises a movable mold and a fixed mold, wherein the movable mold is arranged on a movable mold plate of the injection molding machine, the fixed mold is arranged on a fixed mold plate of the injection molding machine, the movable mold and the fixed mold are closed to form a pouring system and a cavity during injection molding, and the movable mold and the fixed mold are separated during mold opening so as to take out plastic products.

Fig. 1 shows a plastic molded part to be manufactured, which is an upper shell and a lower shell of a lamp housing, and the upper shell and the lower shell are combined together to form the overall appearance of the lamp. In traditional technology, the enterprise can adopt monoblock square stock to carry out the finishing impression under the general condition, treats that the upper casing and lower casing all process and accomplish the back and then make up the assembly, and this processing method not only work efficiency is low, and the cost is improved moreover, is unfavorable for enterprise batch production.

For this reason, the existence of the above problems requires the enterprise engineers to propose corresponding solutions.

Disclosure of Invention

The utility model aims to solve the technical problem that a forming die of lamp housing is provided, the core setting that will go up casing and casing down is in the die cavity of same pair mould, casing and lower casing on can the one-time molding to improve work efficiency, reduce cost.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a forming die of lamp housing, includes mould, lower mould, last mould be provided with the cope match-plate pattern, the lower mould be provided with the framed, framed cover be equipped with mould benevolence, last mould, lower mould, mould benevolence three form the die cavity after making up, mould benevolence include casing core, casing core down, casing core and casing core bilateral symmetry down and terminal surface laminating be connected, the lower mould activity be provided with first slider, second slider, first slider include boss portion, jack portion, boss portion and jack portion fixed connection, the second slider include the lug and with lug fixed connection's contact pin.

As a further improvement of the utility model, the upper casing core and the lower casing core be provided with the reference column, last mould be provided with reference column assorted concave part. The matching of the positioning column and the concave part can ensure the stable and reliable position of the upper die and the lower die when the upper die and the lower die are combined.

As a further improvement of the utility model, the upper shell core and the lower shell core are all fixedly provided with inserts. For the upper shell core and the lower shell core, the upper shell core and the lower shell core are difficult to process in place at one time, so the upper shell core and the lower shell core are assisted by the insert to achieve the purpose of forming.

As a further improvement, the insert is provided with a U-shaped groove, and the central shaft of the groove and the central shaft of the contact pin are the same central shaft. The U-shaped groove is used for forming the lower shell and the inner part of the lower shell, and when the central shaft of the groove and the central shaft of the contact pin are the same axis, the wall thickness of the contact pin hole and the wall thickness of the groove in the diameter direction are guaranteed to be uniform.

As a further improvement of the utility model, the first slider be two sliders of bilateral symmetry, the second slider be two sliders of bilateral symmetry.

As a further improvement of the utility model, the fixed die plate that is provided with of cope match-plate pattern, the lower mould be provided with the roof. The fixed die plate is used for fixedly mounting the upper die plate, and the top plate is used for ejecting the upper shell and the lower shell, so that the demoulding is facilitated.

The utility model has the advantages of can be with last casing core and the casing core setting down in same framed, casing and lower casing on the disposable shaping to improve work efficiency, reduce cost.

In the lower mould, go up casing core and lower casing core bilateral symmetry and laminating mutually, in the framed of lower mould is located to the cover simultaneously, when going up mould, lower mould and merge, but the casing is gone up in the one shot forming and lower casing, can improve work efficiency, and boss portion and the jack portion of first slider are arranged in the left and right sides structure of casing and lower casing in the forming die, and the lug and the contact pin of second slider are arranged in the rear side structure of casing and lower casing in the forming die.
