Abstract
The utility model discloses a seamless tunnel gate structure. The seamless tunnel gate structure comprises a main runner, an auxiliary runner, a gate and a cavity which are communicated in sequence, wherein the tunnel gate is arranged on an integral type die cavity insert below the side of the cavity. According to the seamless tunnel gate structure, the tunnel gate is arranged on the integral type die cavity insert below the side of the cavity, so that only a trace similar to a pin-point gate is reserved on a product due to the hidden splicing manner, a splicing line is not reserved, and the appearance of the product is better.
Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to the seamless structure of a kind of tunnel cast gate.
Background technology
Injection mold is the most general a kind of mould of application in thermoplastic plastic parts production, and its structure is mainly made up of parts such as profiled part, running gate system, guiding parts, ejecting mechanism, thermoregulating system, gas extraction system, support components.Product vestige is little owing to having for tunnel cast gate, can automatically cut off when the demoulding, can fully-automatic production etc. advantage and extensive use.But tunnel cast gate is in manufacture process, and the sprue mold insert that must adopt edge to spell, just can process, and just has like this edge and spell line on product, affects product appearance.
Utility model content
The purpose of this utility model is to provide a kind of seamless structure of tunnel cast gate of spelling line without edge.
For achieving the above object, technical solution of the present utility model is:
The utility model is the seamless structure of a kind of tunnel cast gate, and it comprises sprue, runner, cast gate and die cavity, and described sprue, runner, tunnel cast gate and die cavity sequentially connect; On the monoblock type die cavity that described tunnel cast gate is opened in cavity side below is inserted.
Described runner is opened in monoblock type die cavity and inserts and support on the faying face of inserting.
Adopt after such scheme, the monoblock type die cavity that tunnel cast gate is opened in to cavity side below due to the utility model is inserted upper, and this hidden edge spell shape formula only leaves the vestige of similar spot pouring mouth on product, does not have edge and spells line, and the outward appearance of product is better.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1 at A place.
The specific embodiment
As shown in Figure 1, the utility model is the seamless structure of a kind of tunnel cast gate, and it comprises sprue 1, runner 2, cast gate 3 and die cavity 4.
Described sprue 1, runner 2, tunnel cast gate 3 and die cavity 4 sequentially connect.
As shown in Figure 2, the monoblock type die cavity that described tunnel cast gate 3 is opened in die cavity 4 side-lowers is inserted on 5, and it 5 is parts as die cavity 4 that this monoblock type die cavity is inserted.Described runner 2 be opened in monoblock type die cavity insert 5 with support on 6 the faying face inserted.The monoblock type die cavity that is opened in die cavity 4 side-lowers due to tunnel cast gate 3 is inserted on 5, has reduced the joint line of die cavity 4, makes product edge spell line less.
Emphasis of the present utility model is just: tunnel waters on the monoblock type die cavity that is opened in cavity side below inserts.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
1. the seamless structure of tunnel cast gate, it comprises sprue, runner, cast gate and die cavity, described sprue, runner, tunnel cast gate and die cavity sequentially connect; It is characterized in that: on the monoblock type die cavity that described tunnel cast gate is opened in cavity side below is inserted.
2. the seamless structure of tunnel according to claim 1 cast gate, is characterized in that: described runner is opened in monoblock type die cavity and inserts and support on the faying face of inserting.
