Description

Injection mold

Technical Field

The utility model relates to an injection mold.

Background

Injection molding is a method for producing and molding industrial products. An injection molding machine (an injection machine or an injection molding machine for short) is a main molding device for making thermoplastic plastics or thermosetting materials into plastic products with various shapes by using a plastic molding die, and the injection molding is realized by the injection molding machine and the die. Injection molding is generally classified into the following types:

1. rubber injection molding: rubber injection molding is a production method in which rubber is directly injected from a cylinder into a mold for vulcanization. The rubber injection molding has the advantages that: although the method is an intermittent operation, the forming period is short, the production efficiency is high, the blank preparation process is omitted, the labor intensity is low, and the product quality is excellent.

2. Plastic injection molding: plastic injection molding is a method of producing plastic products by injecting molten plastic into a plastic product mold under pressure, and cooling and molding the plastic product to obtain various plastic parts. There are mechanical injection molding machines that are specifically used for injection molding. The plastic most commonly used today is polystyrene.

3. Molding and injection molding: the resulting shape is often the final product and no further processing is required prior to installation or use as the final product. Many details, such as bosses, ribs, threads, can be formed in a single injection molding operation.

The automobile body guard strip used on the automobile door increases the aesthetic feeling of the side surface of the automobile body, is highly inosculated with the radian of the automobile body, and is durable and non-deformable. Meanwhile, the automobile body paint which is easy to collide when the automobile door is opened and closed is effectively protected.

Fig. 1 shows an automobile part structure, which is an injection molded part, and a technician designs an injection mold for manufacturing the automobile part 112, but during the design process, the side of the part 112 is provided with a notch 111, the notch 111 is partially formed and then buckled in the forming part of the mold, and the formed part cannot be normally demolded.

Disclosure of Invention

The utility model aims to solve the technical problem that an injection mold is provided, the accessory of above-mentioned structure can be demoulded smoothly after the shaping in this injection mold.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: an injection mold comprises a mold body, wherein a plurality of straight ejection mechanisms, a plurality of inclined ejection mechanisms and an oil cylinder assembly are arranged in the mold body, the mold body comprises a top plate and a lower mold forming plate, the lower mold forming plate is provided with an accessory forming groove and a trough, the accessory forming groove is communicated with the trough, the oil cylinder assembly is connected with the top plate, the oil cylinder assembly can drive the top plate to move in the vertical direction, the straight ejection mechanisms comprise straight ejector rods parallel to the vertical direction, the inclined ejection mechanisms comprise inclined ejector rods obliquely arranged in the mold body and guide blocks capable of sliding left and right on the top plate, the straight ejector rods and the inclined ejector rods are movably connected with the lower mold forming plate, the upper ends of the inclined ejector rods are provided with forming end parts, the forming end parts are positioned in the forming grooves, the lower ends of the inclined ejector rods are fixedly connected with the guide blocks, and the lower ends of the straight ejector rods are fixedly connected with the top plate, the upper end of the straight ejector rod is positioned in the trough.

Compared with the prior art, the utility model has the advantages of rational in infrastructure, can be ejecting smoothly in the accessory shaping groove of mould with the accessory after the shaping.

Briefly, the vertical upward movement of oil cylinder subassembly drive roof, the vertical ejecting stub bar that upwards pushes up of straight ejector pin that links firmly with the roof, meanwhile, oblique ejector pin also receives vertical ascending power, but oblique ejector pin receives the spacing of the internal inclined hole of mould, the slope upward movement is simultaneously, draw close to straight ejector pin, the guide block moves towards straight ejector pin side promptly, and fashioned accessory links together with the stub bar, therefore when the vertical upwards being ejected of accessory after the shaping, oblique ejector pin is moving upwards to one side and breaks away from the notch of shaping accessory lateral part gradually.
