Abstract
The utility model relates to an injection mold and particularly relates to an overflowing port of the injection mold. The overflowing port provided by the utility model is more wear-resistant and can be assembled and disassembled. The overflowing port is characterized in that an embedding block is arranged at the part with the overflowing port on a template; one surface of the embedding block is contacted with a cavity; the other part of the embedding block is embedded in the template; an overflowing port on the surface of the embedding block is connected with the overflowing port on the surface of the template; and the side of the overflowing port is arranged in the embedding block. The template at the bottom part of the embedding block is provided with a disassembling hole. The overflowing port has the obvious characteristics and the beneficial effects that the service life of the injection mold is long, the yield rate of products can be guaranteed, and the embedding block is also easily replaced once the round-corner phenomenon occurs on the overflowing port.
Description
Technical field
The utility model relates to injection mold, especially a kind of flash mouth of injection mold.
Background technology
Along with social development, plastic products, aluminum products that people directly or indirectly use are more and more extensive.Now in daily life or industrial various plastic products, aluminum products, major part is manufactured with injection mold.Injection mold in process of production, contains gas in the inner die cavity of injection mold, and raw material has larger pressure when casting gate enters die cavity, if gas is discharged die cavity not in time, the workpiece of institute's moulding just has damaged or pore, affects product quality; So the template surface that has die cavity at injection mold is provided with flash mouth.But the flash mouth that tool is touched in existing injection moulding is defectiveness also, after type intracavity gas is drained, workpiece raw material also can enter flash mouth, and because of raw material, to enter flash mouth pressure larger, and the time has been grown flash mouth and will wear and tear into fillet, the workpiece of producing just has overlap, has affected the quality of product.
Utility model content
The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of flash mouth of the more wear-resistant and injection mold that can load and unload is provided.
In order to realize the purpose of this utility model, the technical scheme adopting is: the position device that is provided with flash mouth in template is inserted, the one side of inserting contacts with die cavity, the other part of inserting is embedded in template, the flash mouth of inserting surperficial is connected with the flash mouth of template surface, and the side of flash mouth is in the inside of inserting.
In the template of the described bottom of inserting, there is removal hole.
Distinguishing feature of the present utility model and beneficial effect are injection mold long service life, and can guarantee the yields of product.Once flash mouth generation fillet phenomenon, inserts and also replaces at an easy rate.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is the cutaway view of the A-A line of Fig. 1.
Fig. 3 is the cutaway view of the B-B line of Fig. 1.
In figure: 1 template, 2 sides, 3 flash mouths, 4 material bags, 5 insert, 6 die cavities, 7 removal holes.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model is further illustrated.
Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of flash mouth of injection mold, at the flash mouth 3 of template 1, by a side of die cavity 6, offer an otch arrangement and insert 5,5 shapes while overlooking of inserting " T " word as English alphabet, insert and 5 make " T " word shape, be to prevent from inserting 5 from otch, to die cavity 6, coming off, asymmetrical one end of " T " word shape is towards type to die cavity 6 and become a face of die cavity 6, inserts 5 and otch tight fit.Flash mouth 3 in template wraps 4 by material and extends to template 1 outside, and the flash mouth 3 of inserting on 5 is connected with the flash mouth 3 of template 1, and in order to guarantee flash mouth 3 intensity, the side 2 of flash mouth 3 is located at 5 inside of inserting.
The template of general injection mold can not adopt steel alloy to make, and is to make of 45# medium carbon steel or of the 45# medium carbon steel through forging, and this is because 45# mild steel material handling ease and material price are relatively cheap.Insert 5 and can adopt all preferably alloy tool steel making of hardness, toughness, wearability, flash mouth 3 just can not become fillet easily, and the good shape of injection mold is Bao Te for a long time, and the qualification rate of product is significantly improved.Insert 5 and template 1 between can load and unload, in the template 1 of inserting below 5, have a demolition hole 7, once flash mouth 3 has wearing and tearing, available instrument impacts from removal hole 75 the bottom of inserting, the 5 disengaging templates 1 that make to insert, what more renew inserts 5.
The above, be only preferred embodiment of the present utility model, not structure of the present utility model done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of the technical solution of the utility model.
