An injection mold with a front mold ejection mechanism

technical field

The utility model relates to the technical field of injection molds, in particular to an injection mold with a front mold ejection mechanism. the

Background technique

Injection molding is a processing method that injects hot-melt plastic material into a closed cavity with the required shape in the mold at high speed, and after the plastic material cools and solidifies, the mold is opened to eject the solidified plastic product to obtain a molded product. Since the injection molding processing method has the characteristics of low molding cost, short molding cycle, simple molding process and easy molding of plastic products with complex shapes, it is widely used in the field of plastic product applications. In terms of injection mold design, the product will also have a buckle on the fixed side of the mold. Generally, the buckle needs to be released through a mechanism such as an oil cylinder, and then the mold is opened. This form increases the cost of the mold, and at the same time the oil cylinder moves slowly, which reduces the production efficiency of the mold. the

The technical solution adopted by the utility model to solve the technical problems is: an injection mold with a front mold ejection mechanism, including a fixed mold, a movable mold and an inclined ejector mechanism, and the fixed mold is provided with an ejector plate on the fixed mold and a fixed mold Lower ejector plate, fixed mold and movable mold are provided with ejection mechanism, and this ejection mechanism includes ejection connecting rod, pull bar, limit block and ejection guide sleeve. the

Further, as a specific form, the upper end boss part of the ejection connecting rod described in the utility model is fixed in the groove on the lower ejector pin plate of the fixed mold, and the ejector guide sleeve is fixed on the fixed mold, and the ejection guide sleeve is fixed on the fixed mold. The connecting rod, the pull rod and the limit block are assembled into one body and arranged in the ejection guide sleeve, and the pull rod is fixed on the movable mold by screws. the

Further, as a specific form, the lower end of the slanting jack mechanism described in the utility model is fixedly installed on the movable mold, and the upper end of the slanting jack mechanism is arranged between the upper ejector plate of the fixed mold and the lower ejector plate of the fixed mold. in the slot. the

Beneficial effects of the utility model: an injection mold with a front mold ejection mechanism of the utility model adopts a fully mechanical compression and pop-up action, has a simple structure and smooth action, and will not adversely affect the structural strength of the mold. Low, the stability of the mold is improved, the action cycle is short, and the efficiency of the mold to produce products is improved. the

Fig. 3 is the assembly diagram of the ejection mechanism of the utility model. the

In the figure 1, fixed mold, 2, movable mold, 3, inclined ejector mechanism, 4, upper ejector plate of fixed mold, 5, lower ejector plate of fixed mold, 6, ejection connecting rod, 7, tie rod, 8, limit block , 9, eject the guide sleeve. the

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These accompanying drawings are all simplified schematic diagrams, only illustrate the basic structure of the utility model in a schematic way, so it only shows the formation relevant to the utility model. the

As shown in Figure 1, Figure 2 and Figure 3, an injection mold with a front mold ejection mechanism includes a fixed mold 1, a movable mold 2 and an inclined ejector mechanism 3, and the fixed mold 1 is provided with an ejector plate 4 on the fixed mold and the lower ejector plate 5 of the fixed mold, the fixed mold 1 and the movable mold 2 are provided with an ejection mechanism, and the ejection mechanism includes an ejection connecting rod 6, a pull rod 7, a limit block 8 and an ejection guide sleeve 9, and the ejection connection The boss part at the upper end of the rod 6 is fixed in the groove on the lower ejector plate 5 of the fixed mold, the ejector guide sleeve 9 is fixed on the fixed mold 1, and the ejector connecting rod 6, the pull rod 7 and the limit block 8 are assembled into one body. In the ejection guide sleeve 9, the pull rod 7 is fixed on the movable mold 2 by screws, the lower end of the tilting jack mechanism 3 is fixedly installed on the movable mold 2, and the upper end of the tilting jack mechanism 3 is set on the fixed mold with the ejector plate 4 and the fixed mold. In the groove between the lower ejector plates 5. the

When the mold is opened, the movable mold 2 is fixed together by the pull rod 7 and the screw. Under the action of the mold opening force of the injection molding machine, the upper ejector plate 4 of the fixed mold and the lower ejector plate 5 of the fixed mold are moved forward together. 8 When the fixed mold 1 is released, the pull rod 7 is separated from the ejection connecting rod 6, and the fixed mold 1 is separated from the movable mold 2 at the same time. At this time, the buckle of the front mold of the product is completely released through the inclined top, and continues to move to the final opening with the movable mold. mode status.

In the same way, during the mold clamping process, the pull rod 7 moves with the movable mold 2. When the limit block 8 touches the ejection guide sleeve 9, the limit block 8 of the ejection guide sleeve 9 snaps into the slot of the pull rod 7. Under the action of the spring force, the upper thimble plate 4 of the fixed mold and the lower thimble plate 5 of the fixed mold are pushed back to the end, thereby completing mold closing. the
