Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a reusable economical insulation feeder device with an efficient feeding function, which includes a feeder cavity 11, and an insulation layer 12 with a preset thickness is disposed on an outer side of the feeder cavity 11, so that a casting liquid in the feeder cavity 11 is maintained in a liquid state within a preset time period, so as to fill a cavity formed by cooling shrinkage during a molding process of the casting liquid in a device cavity.

Based on the property of expansion with heat and contraction with cold, the casting liquid in the device cavity continuously dissipates heat to cause cold contraction to form a cavity in the process of forming the device by solidification, and if the casting liquid in the riser cavity 11 is still maintained in a liquid state in the solidification process of the casting liquid in the device cavity, the casting liquid in the riser cavity 11 can flow back to the device cavity through the casting liquid inlet 111 of the riser cavity, so that the cavity formed by cold contraction in the molding process of the casting liquid in the device cavity can be effectively compensated. It is noted that a predetermined inlet is provided in the device cavity, and the casting process is performed by entering the device cavity through the predetermined inlet 131 and then entering the feeder cavity 11 through the casting liquid inlet 111 of the feeder cavity 11, as an alternative embodiment, the casting liquid enters the device cavity through the casting liquid inlet 111 of the device cavity after filling the device cavity. And in the process of forming the device by solidifying the casting liquid in the device cavity, the casting liquid in the riser cavity 11 flows back to the device cavity through the casting liquid inlet 111, so that the shrinkage caused by solidification of the casting liquid in the device cavity is supplemented.

It is noted that the predetermined thickness is not specifically limited, and may be set according to the solidification rate of the casting liquid and the thickness of the corresponding device, and specifically may be: after the casting liquid in the device cavity is solidified, the casting liquid in the riser cavity 11 is still maintained in a liquid state under the heat preservation effect of the heat preservation layer 12, so that the casting liquid in the riser cavity 11 flows back to the device cavity through the casting liquid inlet 111. However, after a portion of the casting liquid in the riser cavity flows back to the device cavity, the casting liquid in the riser cavity may enter the solidification stage.

In one embodiment of the present invention, the insulating layer 12 is made of refractory fiber paste. The specific setting method may be: the space of the insulating layer 12 may be set first, and then the set space of the insulating layer may be filled with the refractory fiber paste material.

In an embodiment of the present invention, the insulating layer 12 is made of a cotton insulating material, such as insulating cotton. The specific setting method can be as follows: the space of the heat-insulating layer 12 is arranged, then cotton heat-insulating material is laid in the space of the heat-insulating layer 12, and finally the space of the heat-insulating layer 12 is sealed.

According to the reusable economical heat-insulating riser device with the efficient feeding function, after a device casting process is completed, after pouring liquid in a riser cavity is solidified and taken out, the device can be detached and connected with other device cavities again, and only preset outlets of other device cavities are matched with pouring liquid inlets of the riser cavity.

Referring to fig. 2, in a specific application scenario of the reusable economical insulated feeder apparatus with an efficient feeding function provided in the present invention, the casting liquid inlet 111 of the feeder cavity 11 is located at one side. As shown, the device cavity 13 includes a thicker first portion 131 and a thinner second portion 132, and a preset outlet 133 is provided at the right side of the thicker first portion 131, and is connected to the casting liquid inlet 111 of the riser cavity 11 through the second inlet 134, so that the riser cavity 11 is connected to the device cavity 13, and the casting liquid in the riser cavity can flow back to the device cavity 13 through the casting liquid inlet 111 (the preset outlet 133). It is noted that the placement of the casting liquid inlet 111 on the left side of the feeder cavity 11 is merely for convenience of description, and is not a specific limitation that the casting liquid inlet 111 must be placed on the left side of the feeder cavity 11, and it is equally possible to place the casting liquid inlet 111 on the other sides of the feeder cavity 11. Alternatively, the casting liquid inlet 111 may be provided at a corner of the riser cavity 11. The specific location of the casting liquid inlet 111 may be determined according to actual requirements.

In another embodiment of the invention, as shown in fig. 3, the pouring liquid inlet of the feeder cavity 11 is located below. Therefore, when the device cavity generates a gap due to shrinkage in the solidification process, the casting liquid in the riser cavity 11 can flow back to the device cavity under the action of gravity, so that the gap in the device cavity can be effectively fed, and the yield of the device is effectively ensured.

Referring to fig. 4, a schematic view of an application scenario of the reusable economical insulation feeder device with efficient feeding function according to another embodiment of the present invention is shown, in which the device cavity 13 includes at least two portions with different thicknesses, such as a thicker first portion 131 and a thinner second portion 132; a preset outlet 133 is arranged above the thicker first part 131, and is connected with the casting liquid inlet 111 through the preset outlet 133, so that the device cavity 13 is connected with the riser cavity 11; when a gap is formed due to cooling shrinkage in the solidification process of the casting liquid in the device cavity 13, and the casting liquid in the riser cavity 11 is still maintained in a liquid state under the heat preservation effect of the heat preservation layer 12, the casting liquid in the riser cavity 11 flows back to the device cavity 13 through the casting liquid inlet 111 (the preset outlet 133) under the action of gravity, so that the gap formed due to cooling shrinkage in the solidification process of the casting liquid in the device cavity 11 can be effectively compensated, and the casting efficiency and the yield of devices are effectively ensured.

In an embodiment of the present invention, the feeder cavity 11 is made of a metal material, and a melting point of the feeder cavity 11 is higher than a liquid temperature corresponding to the casting liquid. The riser cavity 11 is made of metal, and the melting point of the metal is higher than the liquid temperature corresponding to the casting liquid, so that the riser cavity 11 cannot be melted or deformed due to heating when the liquid casting liquid is injected, and the casting efficiency can be effectively guaranteed.

In an embodiment of the present invention, the top view of the riser cavity 11 is circular, and the riser cavity 11 is circularly arranged based on the circular heat consumption, so that the heat loss rate can be reduced, the liquid time of the casting liquid can be effectively prolonged, and the casting efficiency can be ensured to a certain extent.

In one embodiment of the invention, the shape of the top view of the feeder cavity 11 is elliptical. When the space in which the riser cavity 11 can be arranged in the mold body is not easy to be set to be circular, the shape of the riser cavity 11 can be preferentially considered to be elliptical, the heat can be concentrated, the heat loss rate can be reduced, the liquid time of casting liquid can be effectively prolonged, and the casting efficiency is ensured to a certain extent.

In an embodiment of the invention, a preset gap is arranged between the insulating layer 12 and the riser cavity 11. The preset gap is formed between the heat insulation layer 12 and the riser cavity 11, so that the heat insulation effect of the heat insulation layer 12 is good, and the specific value of the preset gap can be set according to actual requirements, and is determined according to the heat insulation efficiency of the actual requirements and the size of the space outside the device cavity in the mold.

According to the reusable economical heat-insulation riser device with the efficient feeding function, the heat-insulation layer with the preset thickness is arranged on the outer side of the riser cavity, so that the casting liquid in the riser cavity can be still maintained in a liquid state after the casting liquid in the device cavity is solidified, and a cavity formed by solidification of the casting liquid in the device cavity can be filled.

It should be noted that, in the embodiments of the present invention, the term "connected" may be a direct connection or an indirect connection. The connection can be through a wire or other connection structure, such as a hose. The present solution is not particularly limited.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
