Abstract
The invention discloses an investment casting gate stick which comprises a stick body, a motor and a buffering laminar flow device. The buffering laminar flow device is arranged at the bottom of the stick body. The motor is provided with a connecting sleeve. A gate is formed in the top of the stick body. The outer side of the gate is provided with a connecting gear. The connecting gear is engaged with the connecting sleeve through a gear. By means of the investment casting gate stick, the motor is used for driving the whole stick body to slowly rotate so that an alloy solution can be prevented from splashing in the filling process, the flow speed of the alloy solution in a casing cavity in the casting process also can be driven to be increased, and the overall casting speed is increased; due to the buffering laminar flow device, after the alloy solution enters a larger buffering cavity from narrow runners and the buffering cavity is filled with the alloy solution, the flow speed of the alloy solution is reduced, the situation that the decelerated solution splashes from the gate, generates metal particles and enters the cavity is avoided, and the quality of a casting is improved; and the inner runners are evenly and symmetrically formed in all the side faces of a communicating runner, so that it is ensured that the gate stick cannot incline.
Description
Technical field
The present invention relates to a kind of gate stick, particularly to a kind of model casting gate stick.
Background technology
Model casting is also known as lost-wax casting.Model casting typically refers to make apperance at fusible material, if making shell at apperance Surface coating dried layer refractory material, then apperance fusing is discharged shell, thus obtains the casting mold without die joint, gets final product the founding method of back-up sand cast after high-temperature roasting.Owing to the widely used wax material of apperance manufactures, therefore often model casting is referred to as lost-wax casting, and the pouring procedure of existing casting is to use traditional precision casting technology design concept to design.Due to hot investment casting part product compared with sand foundry goods less, it is impossible to sand casting equally use single running gate system, can only be poured into a mould by runner system.Rising head casting is that alloy molten solution directly pours into following die cavity from watering casting rod running channel, speed owing to pouring at the beginning is fast, producing little metallic particles entrance die cavity from cast gate alloy molten solution meeting splash out, this defect is mostly owing to product metallic particles produced that splashes of alloy molten solution in casting process enters generation after die cavity mixes with alloy molten solution with generating relatively thick oxide film.To this end, it is proposed that a kind of model casting gate stick.
Summary of the invention
nullA kind of model casting gate stick of offer is provided，Slowly rotated by the whole barred body of driven by motor and be so possible not only to prevent alloy solution from occurring when pouring into situation about splashing can also drive the flow velocity in casting type intracavity portion of the alloy solution in cast，Thus accelerate the poring rate of entirety，By buffering laminar flow device，After alloy molten solution enters bigger cushion chamber in narrow running channel，After cushion chamber is filled，The reduced velocity flow of alloy molten solution，Liquation after slowing down will not splash from cast gate and produce metallic particles entrance die cavity，Liquation is to pour into from watering casting rod upper end simultaneously，The alloy molten solution of front end can produce a thick layer of oxide-film with the oxygen effect in running channel air after entering running channel，The oxide layer of alloy molten solution can be introduced into cushion chamber，Die cavity will not be entered，Prevent forming curves shape and irregular cast defect in alloy-steel casting，Improve the quality of cast，By each side at through running channel, ingate is set symmetrically，The centre-of gravity shift of gate stick can be avoided，Ensure gate stick not run-off the straight，Can effectively solve the problem in background technology.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of model casting gate stick, including barred body, motor and buffering laminar flow device, buffering laminar flow device it is provided with bottom described barred body, described motor is provided with adapter sleeve, described barred body top is provided with cast gate, is provided with connection gear outside described cast gate, and described connection gear and adapter sleeve are engaged by gear, described barred body is provided with through running channel, ingate on described through running channel.
Further, cushion chamber, described through running channel connection cushion chamber it are provided with in described buffering laminar flow device.
Further, described cushion chamber horizontal cross-section is rectangle, described in run through running channel horizontal cross-section for circle.
Further, described ingate both sides are equipped with reinforcement.
Further, it is provided with prolongation running channel between described through running channel and cushion chamber.
nullCompared with prior art，There is advantages that slowly to be rotated by the whole barred body of driven by motor and be so possible not only to prevent alloy solution from occurring when pouring into situation about splashing can also drive the flow velocity in casting type intracavity portion of the alloy solution in cast，Thus accelerate the poring rate of entirety，By buffering laminar flow device，After alloy molten solution enters bigger cushion chamber in narrow running channel，After cushion chamber is filled，The reduced velocity flow of alloy molten solution，Liquation after slowing down will not splash from cast gate and produce metallic particles entrance die cavity，Liquation is to pour into from watering casting rod upper end simultaneously，The alloy molten solution of front end can produce a thick layer of oxide-film with the oxygen effect in running channel air after entering running channel，The oxide layer of alloy molten solution can be introduced into cushion chamber，Die cavity will not be entered，Prevent forming curves shape and irregular cast defect in alloy-steel casting，Improve the quality of cast，By each side at through running channel, ingate is set symmetrically，The centre-of gravity shift of gate stick can be avoided，Ensure gate stick not run-off the straight.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, the present invention is expanded on further.
As shown in Figure 1, a kind of model casting gate stick, including barred body 4, motor 8 and buffering laminar flow device 11, being provided with buffering laminar flow device 11 bottom described barred body 4, described motor 8 is provided with adapter sleeve 5, and described barred body 4 top is provided with cast gate 7, connection gear 6 it is provided with outside described cast gate 7, described connection gear 6 and adapter sleeve 5 are engaged by gear, and described barred body 4 is provided with through running channel 9, ingate 3 on described through running channel 9.
One model casting gate stick of the present invention, by cast gate 7, alloy solution is injected in barred body 4, alloy solution flows down by running through running channel 9, extend running channel 10 and have certain buffering effect, whole cushion chamber 1 is filled up when alloy solution continues cast, alloy solution can pass sequentially through ingate 3 and flow out, thus fills up whole casting die cavity, barred body can be driven to rotate by motor 8.
Wherein, being provided with cushion chamber 1 in described buffering laminar flow device 11, described through running channel 9 connects cushion chamber 1, is possible to prevent alloy solution in casting cycle to produce metallic particles from cast gate splashing by buffering laminar flow device 11 and enters die cavity.
