Description
Technical field
The present invention relates to plastic injection mold field, more particularly to a kind of male die core of key button injection mold.
Background technology
The manufacturing of the injection molding due to being widely used in plastic products the advantages of possessing efficient, high-quality.Injection
Mould is typically put together by two pieces of dies, and mould inside is provided with the runner and die cavity being sequentially communicated.During injection machine injection molding,
Melt by barrel be pumped through nozzle, running channel after reach die cavity so that formed product.But the product of many small volumes, such as
Fruit single product designs a mould and produced, and processing efficiency is low, such as the remote-control key button accessory shown in Fig. 5, because
This can arrange multiple die cavities in die so that multiple products are molded simultaneously, to improve production efficiency.But often occur
Product and the halfway situation of waste material discharging, so, have a negative impact to secondary injecting glue, and how as far as possible discharging is thoroughly
In the urgent need to address the problem of.
The content of the invention
For above-mentioned technical problem, the purpose of the present invention is：Propose a kind of good key button of discharging effect
The male die core of injection mold.
What the technical solution of the present invention was realized in：A kind of male die core of key button injection mold, including mould
Benevolence body；The upper surface middle part of the die body offers horizontal sprue；On the upper surface of the die body two-by-two
Eight die cavities are symmetrically and evenly provided with, and the die cavity is symmetrically distributed in the both sides of sprue；The two ends difference of the sprue
It is symmetrically arranged with two I-shaped secondary channels；The corner of each I-shaped secondary channels is connected by Qian Jiao roads with four die cavities
It is logical；The die body interior and the hollow cooling water channel that an open-ended is offered below die cavity；The cooling
The water inlet and delivery port in water route are arranged on the bottom face of die body；It is symmetrical arranged below the two ends end of the die cavity
There is discharging centre hole；Main glue centre hole is provided with below the middle part of the sprue；The transverse direction of each I-shaped secondary channels with
Vertical-sprue infall is provided with secondary glue centre hole.
It is preferred that, the cooling water channel is looped around the outside of eight die cavities.
It is preferred that, the upper surface corner corner of the die body offers locating slot.
It is preferred that, the bottom of the die body is provided with four threaded mounting holes at corner.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
The male die core of the key button injection mold of the present invention, in order to improve product injection efficiency, arranges on male die core and opens up
There are eight die cavitys, pass sequentially through sprue, secondary channels, Qian Jiao roads and die cavity is carried out to enter glue sideways, one time injecting glue can be produced simultaneously
Eight products；After die sinking, smoothly product and scrap rubber are all pushed up by discharging centre hole, main glue centre hole and secondary glue centre hole
Go out, discharging thoroughly and injection molding product qualification rate it is high.
