Abstract
A sprue for jolt moulding comprises a gate sprue, wherein the lower end of the gate sprue is an inverse cone shape, the lower bottom surface of the gate sprue is detachably connected with a shaping plate, a sprue hopper is clamped on the upper part of the gate sprue, and a spring is arranged between the sprue hopper and the gate sprue. The sprue is simple in process and is time-saving and labor-saving; a good sand mould compression effect is obtained, fillets are in smooth transition, and a casting sand inclusion defect which is caused by sandblasting is effectively avoided; a conventional inverse flared gate sprue is changed into a closed gate sprue, a good residue blocking effect is obtained, and air pores are not easy to generate; and the sprue has a light weight and high molten iron utilization rate, the cost is lowered, and the single gate sprue can save 1-3 kilograms of molten iron according to the gate sprues with different heights.
Description
Technical field
The present invention relates to a kind of pouring gate for jolt molding.
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 ram-jolt, that all adopts inverted tubaeform directly waters rod, and the processing method of the cast gate of sand mold a kind of be after compacting, to use excavated by manual work, another kind of way is exactly to imbed a model behind for the first time compacting of pressure head sand mold again, compacting is taken out later on model 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, water buccal funnel more open with the sand that directly waters excellent junction, round-corner transition is rough, and easily casting flaws such as forming burning into sand is made in sand washing.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 the casting flaws such as slag inclusion or pore.4, the sprue of falling the trumpet type is heavy, the waste molten iron.
Summary of the invention
The technical problem that the present invention solves is, a kind of pouring gate for jolt molding is provided, and the cast gate manufacturing that has solved sand mold is wasted time and energy and the improper and problem of the waste molten iron that causes of sprue shape.
The technical solution used in the present invention is:
A kind of pouring gate for jolt molding comprises sprue, and the lower end of described sprue is the bodily form of falling from power, and bottom surface and the template of sprue removably connect, and is covered with above sprue and waters buccal funnel, waters between buccal funnel and the sprue and is provided with spring.
Beneficial effect of the present invention is:
Operation of the present invention is simple, saving of work and time; The sand mold consolidation effect is good, and the transition of fillet place is round and smooth, 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; Lightweight, the molten iron utilization rate is high, has reduced cost, and different according to the sprue height, single sprue can be saved molten iron 1-3 kilogram.
Description of drawings
Fig. 1 is the schematic diagram that sprue of the present invention uses.
Fig. 2 is the partial structurtes schematic diagram of sprue of the present invention after template is combined.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment:
As shown in drawings, a kind of pouring gate for jolt molding comprises sprue 3, the lower end of sprue 3 is the bodily form of falling from power, bottom surface and the template of sprue removably connect, and are covered with above sprue 3 and water buccal funnel 1, water between buccal funnel 1 and the sprue 3 and are provided with spring 2.
During use, as shown in drawings, can be provided with at the bottom surface of sprue 3 running-on 4, sprue 3 is plugged on the latch 5 fixing on the template 6 by running-on 4; Cross gate 7 and ingate are placed on the template 6.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, then one pull out and can take out, very convenient.
Claims (1)
1. a pouring gate for jolt molding comprises sprue, it is characterized in that, the lower end of described sprue is the bodily form of falling from power, and bottom surface and the template of sprue removably connect, and is covered with above sprue and waters buccal funnel, waters between buccal funnel and the sprue and is provided with spring.
