CN202922900U - Novel submarine gate - Google Patents

Abstract

The utility model relates to a spare part of a die, and particularly relates to a novel submarine gate. The novel submarine gate comprises a submarine gate body, wherein the section shape of a pouring point of the submarine gate body is an ellipse. The section of the pouring point is arranged into the ellipse, so that the pouring area is over twice greater than the round gate; the target of automatically cutting off a water gap also can be achieved; the injection pressure injury is small on the premise of a simple process; and the product is fully filled easily.

Description

A kind of novel latent cast gate

Technical field

The utility model relates to a kind of parts of mould, relates in particular to a kind of novel latent cast gate.

Background technology

The injecting products of full-automatic machinery production often advances cast gate in the product injection moulding and makes latent watering, and to reach automatic shutoff mouth aborning, removes to deduct the cost at the mouth of a river to save manpower.

The advantages such as the general cast gate of diving advances to water a little to be circle, and for the product of rule, this advances to water reliably, and the mouth of a river is easily broken.

But for irregular product, the muscle position is dark, if or adopt circular to advance to water a little, product is not easy to be filled full when injection moulding, and product often has the generation of starved.

And traditional advance to water a little for circular, product advances cast gate less in the time of injection moulding, and the injection pressure of damage is very large.

The utility model content

Defective and deficiency that the utility model exists in order to solve above-mentioned prior art provide a kind of injection pressure damage little, the easier injection moulding of product, and novel latent cast gate easy to process.

The technical solution of the utility model: a kind of novel latent cast gate, comprise the cast gate body of diving, a cross sectional shape that advances to water of described latent cast gate body is ellipse.

Preferably, described latent cast gate body advances to water a little minor axis length＜1.2mm.

Ellipse is arranged in the cross section that the utility model will advance to water a little, makes it advance to water the large more than 2 times of Area Ratio circle, makes it can reach the purpose of automatic shutoff mouth equally, processes under simple prerequisite, and the injection pressure damage is little, and product easily is filled full.

Description of drawings

Fig. 1 is structural representation of the present utility model.

In figure, 1. latent cast gate bodies, 2. advance to water a little.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not restriction to the utility model protection domain.

As shown in Figure 1, a kind of novel latent cast gate comprises the cast gate body 1 of diving, the cast gate body 1 of diving advance to water a little that 2 cross sectional shapes are ellipse.Advance to water a little minor axis length＜1.2mm of 2.

Ellipse is arranged in the cross section that the utility model will advance to water a little, makes it advance to water the large more than 2 times of Area Ratio circle, makes it can reach the purpose of automatic shutoff mouth equally, processes under simple prerequisite, and the injection pressure damage is little, and product easily is filled full.

Claims (2)

1. a novel latent cast gate, comprise the cast gate body of diving, and it is characterized in that: a cross sectional shape that advances to water of described latent cast gate body is ellipse.

2. a kind of novel latent cast gate according to claim 1 is characterized in that: described latent cast gate body advance to water a little minor axis length＜1.2mm.
