Description
Technical Field
The utility model relates to an injection mold relates to a button injection mold for highlight class.
Background
Plastics are a general name of articles for daily use and industrial products which are processed by adopting plastics as main raw materials. An injection mold is a tool used in the injection molding industry to match an injection molding machine and give the injection molded article a complete configuration and precise dimensions. Because of the variety of injection molding and processing methods, and the structure of injection molding machines and injection products are various, the variety and structure of injection molds are also various.
The utility model provides an injection mold for highlight product design.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a button injection mold for highlight class for produce the special mould of the high-quality high-finish product.
The technical scheme is as follows: the utility model discloses a key injection mold for highlight, which comprises a bottom plate; the bottom plate is sequentially provided with a supporting plate, ejector pins fixed on the base and vertically arranged, a lower template, an upper template, a pressing plate for fixing the upper template and a main runner, wherein the main runner is positioned in the pressing plate and communicated with the upper template, auxiliary runners are arranged on the side walls of the pressing plate and the supporting plate, and branch runners for injecting liquid plastics into the templates are arranged at the upper template.
By adopting the technical scheme, the upper template and the lower template are closed, then the liquid plastic is injected into the main runner and the auxiliary runner, the liquid plastic of the main runner, the sub-runner and the auxiliary runner flows into a product cavity formed between the upper template and the lower template, after cooling, a product is formed, the pressing plate is pressed downwards, the ejector pins eject the product, then the pressing plate moves upwards, and the product is taken out.
Has the advantages that: the die has reasonable structure and can produce high-quality products; multi-directional injection molding improves the injection molding speed and reduces the product generation time; due to the arrangement of multiple air passages, the cooling time of the product is reduced, and the generation efficiency is improved; the upper and lower templates are detachably connected with the whole die, so that the replacement speed and difficulty are improved.

Detailed Description
As shown in fig. 1 to 3, an injection mold for a highlight key includes a base plate 1; the bottom plate 1 is sequentially provided with a supporting plate 2, a thimble 3 which is fixed on the base and is vertically arranged, a lower template 4 which is positioned in the supporting plate 2, an upper template 5, a pressing plate 6 which is used for fixing the upper template 5 and a main runner 7 which is positioned on the pressing plate 6 and is communicated with the upper template 5, the side walls of the pressing plate 6 and the supporting plate 2 are provided with auxiliary runners 8, and the upper template 5 is provided with a sub-runner 9 which is used for injecting liquid plastics into each template.
Closing the upper template 5 and the lower template 4, then injecting liquid plastic into the main runner 7 and the auxiliary runner 8, enabling the liquid plastic of the main runner 7 and the auxiliary runner 8 to flow into a product cavity formed between the upper template 5 and the lower template 4, after cooling, forming a product, pressing the pressing plate 6 downwards, ejecting the product by the ejector pin 3, then moving the pressing plate 6 upwards, and taking out the product.
In order to rapidly reduce the temperature of the product in the template, the surface of the upper template 5 is provided with air holes 10 for reducing the temperature.
When the product is ejected and the upper template 5 and the lower template 4 are closed, the pressing block moves up and down relative to the supporting plate 2, so that in order to keep the stability of the movement of the pressing plate 6, a slideway 11 is arranged on the supporting plate 2, and a guide rod 12 used for being matched with the slideway 11 is arranged on the pressing plate 6; the guide bar 12 moves up and down in the slide 11 in accordance with the up and down movement of the platen 6.
As shown in fig. 2, 4 and 5, in order to facilitate the detachment between the lower template 4 and the support plate 2, the bottom of the lower template 4 is provided with a pin block 13 for connecting with the support plate 2, and the pin block 13 comprises a built-in sliding groove 131 and a pin hole 132 on the side wall; install the backup pad 2 with lower bolster 4 on, the accuracy of the installation between backup pad 2 and the lower bolster 4 of being convenient for is gone up spout 131 on the lower bolster 4 and the protruding cooperation in the backup pad 2, and pinhole 132 on the 4 round pin piece 13 of lower bolster and the pinhole on the lug in the backup pad 2 of lower bolster pass through the round pin simultaneously and fix, and later stage also is convenient for dismantlement between the two. The upper template 5 and the lower template 4 are matched for use, and the connection mode of the upper template 5 and the pressing plate 6 is consistent with the connection relationship between the lower template 4 and the supporting plate 2.
In order to facilitate the later modification and the taking out of the product, the lower template 4 is provided with a receiving groove 14 for injection molding excess materials; the accommodating groove 14 is used for accommodating allowance plastics, so that a gap is reserved between a product and the lower template 4, and after the product is molded, the ejector pin 3 ejects the product from the lower template 4.
