Description

A kind of drum washing machine motor shell forming mold

technical field

The utility model relates to the field of injection moulds, in particular to a drum washing machine motor shell forming mould.

Background technique

Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding.

With the rapid development of the plastics industry and the continuous improvement of the strength of general-purpose and engineering plastics, the application scope of plastic products is also expanding, and the amount of plastic products is also rising.

A plastic mold is a tool for producing plastic products. It consists of several groups of parts, and this combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, and then the upper and lower molds are separated, and the product is ejected from the cavity through the ejection system to leave the mold, and finally the mold is closed again. For the next injection, the entire injection process is cyclic.

Generally, a plastic mold consists of a movable mold and a fixed mold. The movable 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 a gating system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product.

Although the structure of the mold may vary due to the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature regulation system, forming parts and structural parts. Among them, the gating system and the 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 changeable parts in the mold, and require the highest processing finish and precision.

Figure 1 shows the structure of a drum washing machine motor casing. It is the most reasonable production method to use mold injection for mass production at present. In view of this, those skilled in the art improve the traditional mold used for molding the plastic part.

SUMMARY OF THE INVENTION

The technical problem to be solved by the utility model is to provide a drum washing machine motor shell forming mold, which is intended to shorten the processing cycle of the mold and reduce the development cost of the mold by simplifying the structure of the mold base.

The technical scheme adopted by the utility model to solve the above technical problems is as follows: a drum washing machine motor shell forming mold, which includes a mold base body, and the mold base body includes an upper mold frame, a lower mold frame and a top plate. The upper mold frame is provided with an upper mold forming plate, the upper mold forming plate is provided with a plurality of upper mold cores that are assembled, the lower mold frame is provided with a lower mold core, and the lower mold core is provided with A cylindrical inner cavity, a cylindrical mold core is arranged in the inner cavity, a first molding gap is reserved between the mold core and the inner wall of the inner cavity, and a jacket and a lower mold core, the upper mold core is The mold core is arranged above the lower mold core and a second forming gap is reserved therebetween, and the first forming gap is communicated with the second forming gap.

A further preferred solution of the present invention: the inner wall of the inner cavity is provided with a plurality of crisscross grooves.

A further preferred solution of the present invention is that the upper die core includes a disc-shaped first insert and a plurality of second inserts spliced around the first insert, and the lower die core includes a plurality of forming sliders.

A further preferred solution of the present invention: the forming slider is provided with a core rod inserted into the first forming gap, and a core pulling slider connected with the core rod.

Compared with the prior art, the utility model has the advantages that the structure of the mold base is simplified, the development cycle of the mold is shortened, and the first molding gap is reserved between the mold core and the inner wall of the inner cavity for molding the side wall of the shell, and the upper The mold core is arranged above the lower mold core and a second forming gap is reserved between the two for forming the bottom of the cylinder.
