Abstract

The utility model belongs to the technical field of casting, particularly relates to a novel spring gate device used for a modeling and gating system for a vibrating compaction machine. The novel spring gate device solves the problems of time consuming and labor consuming of sand model gate manufacture, hot iron waste led by unsuitable sprue shape, and the like in a machine modeling process in the prior art. The novel spring gate device used for the modeling and gating system for the vibrating compaction machine comprises a sprue, the lower end of the sprue is of an inverted stage body shape, a sleeve hole is arranged on a lower bottom surface of the sprue, the upper part of the sprue is locked and sleeved with a gate funnel, and a spring is arranged between the gate funnel and the sprue. The novel spring gate device used for the modeling and gating system for the vibrating compaction machine has the advantages of reasonable structure, simple procedure, labor conservation, time conservation and favorable sand model compaction effect.

Description

The novel spring gating apparatus

Technical field

The utility model belongs to casting technology field, is specially a kind of novel spring gating apparatus of real machine moulding running gate system that jolt-squeezes that is used to.

Background technology

In machine molding, the running gate system on the sand mold and unlike hand moulding by hand instrument work it out, generally be that cross gate and ingate are placed on the template, sprue then needs to see the method for rramming and determines its structure.When rramming adopts the way of jolt-squeezing real, that all adopts inverted tubaeform directly waters rod, and the processing method of the cast gate of sand mold a kind of be with manually digging after compacting, another kind of way is exactly to imbed a model again behind pressure head compacting for the first time sand mold, and compacting is taken out model later on and can be formed and water buccal funnel again.But do like this and have following drawback: 1, operation is loaded down with trivial details, take a lot of work, time-consuming, effort.2, it is more open with the sand that directly waters excellent junction to water buccal funnel, and round-corner transition is rough, and casting flaws such as forming burning into sand is made in sand washing easily.3, inverted tubaeform directly waters rod, and the pushing off the slag effect is bad, and air is easy to enter molten iron and is brought into die cavity, thereby causes casting flaws such as slag inclusion or pore.4, the sprue of falling trumpet type heaviness, the waste molten iron.

Summary of the invention

The utility model is in order to solve in the machine molding process that exists in the prior art, and the cast gate manufacturing of sand mold is wasted time and energy and the improper and problem such as waste molten iron of causing of sprue shape and a kind of novel spring gating apparatus is provided.

The utility model is realized that by following technical scheme a kind of novel spring gating apparatus comprises sprue, the lower end of sprue is the bodily form of falling from power, bottom surface at sprue is provided with running-on, is covered with to water buccal funnel above sprue, waters between buccal funnel and the sprue and is provided with spring.

In the time of machine molding, sprue is plugged on the latch of template.When pressure head presses down sand, water buccal funnel and also move down along sprue, after sand is compacted pressure relief, water buccal funnel bullet under the active force of spring, one pull out and can take out then, very convenient.

Compare with the existing manual device of making cast gate, the utility model is rational in infrastructure, and operation is simple, saving of work and time; The sand mold consolidation effect is good, and fillet place transition slyness, has effectively avoided sand washing to cause the defective of foundry goods burning into sand; The inverted tubaeform sprue that becomes in the past is closed sprue, and not only pushing off the slag is effective, and is not easy to produce pore; In light weight, molten iron utilization rate height has reduced cost, and according to sprue height difference, single sprue can be saved molten iron 1-3 kilogram.

The specific embodiment

As schematically shown in Figure 1, a kind of novel spring gating apparatus comprises sprue 3, the lower end of sprue 3 is the bodily form of falling from power, bottom surface at sprue 3 is provided with running-on 4, is covered with above sprue 3 and waters buccal funnel 1, waters between buccal funnel 1 and the sprue 3 and is provided with spring 2.

Sprue 3 is plugged on the latch 5 fixing on the template 6 by running-on 4.

Claims

1, a kind of novel spring gating apparatus, it is characterized in that: comprise sprue (3), the lower end of sprue (3) is the bodily form of falling from power, bottom surface at sprue (3) is provided with running-on (4), be covered with in the top of sprue (3) and water buccal funnel (1), water between buccal funnel (1) and the sprue (3) and be provided with spring (2).
