The existing mold has few injection molding channels, molten plastic is extruded into a cavity in the mold through a single channel, the plastic diffusion speed is low, the product molding time is long, and the stability is poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a printer housing preparation mould, the product shaping is more stable.

The utility model provides a technical scheme that its technical problem adopted is: a printer shell preparation mold comprises a fixed mold and a movable mold, wherein after the fixed mold and the movable mold are assembled, a cavity for product molding is formed between the fixed mold and the movable mold; the fixed die is connected with an injection molding port; a plurality of injection molding channels communicated with the injection molding ports are also arranged in the movable mold; the injection molding channel is communicated with the cavity. Molten plastic is injected into a cavity between the fixed die and the movable die through the injection molding channels arranged in the fixed die, so that the injection speed of the molten plastic is increased, the product molding time is shortened, and the product molding stability is improved.

Further, the method comprises the following steps: the injection molding channels are four in total. According to the shape of the printer shell, four injection molding channels are uniformly arranged in the fixed die, so that the injection speed of the molten plastic is improved.

Further, the method comprises the following steps: and the movable die is provided with a guide post for positioning.

Further, the method comprises the following steps: and a guide groove matched with the guide column is arranged in the fixed die. When the die is closed, the guide post is inserted into the guide groove, so that the movable die is positioned, the die can be prevented from deviating during die closing, and the product quality is ensured.

Further, the method comprises the following steps: and the movable die is also provided with an ejection device for demoulding of the product. The mold is opened after the product is molded, the product moves along with the movable mold, and the ejection device can eject the product quickly, so that the product is demolded.

Further, the method comprises the following steps: and cooling channels are arranged in the fixed die and the movable die, and a cooling liquid inlet and a cooling liquid outlet are arranged at the two ends of each cooling channel. The cooling liquid circulates in the cooling channel, so that the molten plastic injected into the cavity can be rapidly cooled, solidified and molded, the molding time of the product is shortened, and the production efficiency is improved.

Drawings

FIG. 1 is a schematic diagram of a printer housing preparation mold.

Labeled as: 100. fixing a mold; 200. moving the mold; 210. a guide post; 300. an injection molding port; 310. injection molding a channel; 400. and (4) an ejection device.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, a printer housing preparation mold comprises a fixed mold 100 and a movable mold 200, wherein when the fixed mold 100 and the movable mold 200 are closed, a cavity for product molding is formed between the fixed mold 100 and the movable mold 200; the fixed die 100 is connected with an injection molding port 300; a plurality of injection molding channels 310 communicated with the injection molding ports 300 are also arranged in the movable mold 200; the injection channel 310 communicates with the cavity. The connecting part of the injection molding channel 310 and the cavity is a feeding port far away from injection, and the feeding port can be uniformly arranged around the cavity according to the shape of a product.

On the basis of the above, as shown in fig. 1, the injection molding channels 310 have four injection molding channels.

In addition, as shown in fig. 1, the movable mold 200 is provided with a guide post 210 for positioning.

In addition, as shown in fig. 1, a guide groove engaged with the guide post 210 is formed in the fixed mold 100.

In addition, as shown in fig. 1, the movable mold 200 is further provided with an ejector 400 for demolding the product. In order to facilitate the clamping of the molded product, the ejector 400 is required to eject the product from the movable mold 200, and an ejector pin or an ejector sleeve may be used, and in this example, the ejector 400 is an ejector pin.

During actual production, the movable mold 200 and the fixed mold 100 are in a mold closing state, plastic in a molten state is injected into the cavity through the injection channel 310 at the moment, after mold materials are cooled, the movable mold 200 is opened, and the molded printer shell is clamped in the movable mold 200 and moves together with the movable mold 200 at the moment; when the movable mold 200 moves in place, namely the mold opening is completed, the product clamping device is waited to be in place, the ejection device 400 is ejected forwards, and the product is ejected out of the movable mold 200, so that the product can be conveniently clamped. The feeding ports of the injection molding channels 310 are uniformly distributed around the cavity according to the shape of the product, so that the injection molding speed is increased, the whole cavity can be filled with the plastic in a molten state more quickly, and the forming speed of the product is increased.

On the basis, as shown in fig. 1, cooling channels are arranged in the fixed die 100 and the movable die 200, and a cooling fluid inlet and a cooling fluid outlet are arranged at two ends of each cooling channel. The mould material gets into the cavity in the cooling process, lets in cooling channel with the coolant liquid, and the coolant liquid takes away the heat in the mould in the flow process, flows from the coolant liquid export again for the shaping is cooled off rapidly to the high temperature mould material in the cavity, can shorten the fashioned time of product cooling, improves production efficiency. Cold water may be used as the cooling liquid.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
