Abstract
The invention discloses a flexible glue runner ejector pin which is applied to molds. The flexible glue runner ejector pin comprises an ejector pin countersunk head as well as an ejector pin rod, wherein the ejector pin countersunk head is arranged at the tail end of the ejector pin rod; the outer diameter of the tail end is less than that of the head end at the other end of the ejector pin rod; the head end of the ejector pin rod is in contact with a runner, and an integral transition end is also arranged between the tail end and the head end of the ejector pin rod; the outer diameter of the transition end is increased gradually in the direction from the tail end to the head end. According to the flexible glue runner ejector pin provided by the invention, a flexible glue runner and a mold plate generate a pocket hole when the flexible glue runner is arranged in a mold by changing outer diameters of different sections of the ejector pin rod, so that overflow glue falls out of the mold from the pocket hole, the phenomenon the clamping of the flexible glue runner ejector pin by the overflow glue is prevented, and the mold cost is reduced.
Description
[technical field]
The present invention relates to a kind of thimble, be specifically related to a kind of thimble for top flexible glue runner.
[background technology]
Thimble, when the flexible glue runner of top, when service time is long, easily grinds gap between thimble and runner, and because flexible glue is more liquid, glue especially easily overflows.Refer to shown in Fig. 1, the flexible glue runner thimble 10 of prior art is when the flexible glue runner 20 of top, and excessive glue makes thimble 10 easily stuck, need to change thimble or incision, has greatly increased die cost.
In view of this, be necessary to develop in fact a kind of novel flexible glue runner thimble, this novel flexible glue runner thimble can avoid overflowing glue by the stuck phenomenon appearance of thimble.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of novel flexible glue runner thimble, this flexible glue runner thimble can avoid overflowing glue by the stuck phenomenon generation of thimble, has reduced die cost.
In order to achieve the above object, flexible glue runner thimble of the present invention, is applied in mould, and this flexible glue runner thimble comprises:
Thimble countersunk head; And
Thimble rod, above-mentioned thimble countersunk head is located at the tail end of this thimble rod, the outside dimension of this tail end is less than the outside dimension of thimble rod other end head end, this thimble rod head end contacts with runner, and between the tail end of this thimble rod and head end, be also provided with the transitioning end of one, it is large that the outside dimension of this transitioning end becomes gradually in the direction to head end from tail end.
Especially, described flexible glue runner thimble is column.
Especially, the outside dimension of described thimble countersunk head is greater than the outside dimension of thimble rod.
Especially, when described flexible glue runner thimble is located in mould, between the tail end of thimble rod and transitioning end and mould template, produce emptiness avoiding hole.
Compared to prior art, flexible glue runner thimble of the present invention, by the outside dimension of conversion thimble rod, thereby while making flexible glue runner in being located at mould, produce emptiness avoiding hole with mould template, make excessive glue from emptiness avoiding hole, drop out mould, avoided excessive glue that the stuck phenomenon of flexible glue runner thimble is occurred, reduced die cost.
[accompanying drawing explanation]
Fig. 1 illustrates the structural representation of prior art flexible glue runner thimble.
Fig. 2 illustrates the structural representation of flexible glue runner thimble of the present invention.
Fig. 3 illustrates the local enlarged diagram of flexible glue runner thimble of the present invention in mould.
[specific embodiment]
Refer to shown in Fig. 2, flexible glue runner thimble of the present invention, is applied in mould, and in the present embodiment, this flexible glue runner thimble 100 is column, and it comprises:
Thimble rod 120, above-mentioned thimble countersunk head 110 is positioned at the tail end 121 of this thimble rod 120, the outside dimension of the tail end 121 of this thimble rod 120 is less than the outside dimension of thimble rod 120 other end head ends 122, the head end 122 of this thimble rod 120 contacts with runner 200, and 122 of the tail end 121 of this thimble rod 120 and head ends are also provided with the transitioning end 123 of one, it is large that the outside dimension of this transitioning end 123 becomes gradually in the direction to head end 122 from tail end 121.This transitioning end 123 has strengthened the intensity of this flexible glue runner thimble 100, prevents that this flexible glue runner thimble 100 from fractureing.
Wherein, the outside dimension of described thimble countersunk head 110 is greater than the outside dimension of thimble rod 120.When this flexible glue runner thimble 100 is placed in to mould, in mould, be provided with corresponding holding tank located therein for this flexible glue runner thimble 100.
Refer to shown in Fig. 3, the head end 122 of thimble rod 120 matches with the holding tank of mould, for sealing; And due to the tail end 121 of thimble rod 120 and the outside dimension of transitioning end 123 less, and 300 of mould templates have produced emptiness avoiding hole 310, flexible glue runner thimble 100 is ejecting and excessive adhesive tape can entered during return in described emptiness avoiding hole 310 like this, excessive glue can drop out mould along the emptiness avoiding hole 310 of mould template 300, avoided excessive glue by the stuck phenomenon of this flexible glue runner thimble 100, reduce the action of changing thimble or inserting piece, saved die cost.
