Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to foam mould feeding equipment. Background Art

[0002] Lost foam casting is a process of bonding wax or foam models that are similar in size and shape to the casting into a model cluster, brushing refractory coating and drying, burying it in dry quartz sand for vibration molding, pouring under negative pressure to vaporize the model, and liquid metal occupies the model position. Lost foam casting requires the manufacture of a foam mold, and then the foam mold needs to be fed into the mold for plasticity using a feeding device.

[0003] Some equipment on the market generally expands the foam raw materials through a steam pre-foaming machine, and then transmits the foam to the inside of a storage box through a feed pipe, and then transports it to the inside of a mold through high-pressure gas for heating and forming when in use.

[0004] However, during actual use of the above equipment, the heated foam may stick together due to overheating when entering the storage box, thereby blocking the material when it is transmitted out of the storage box; in view of this, we propose a foam mold feeding device. Utility Model Content

[0005] The purpose of the utility model is to provide a foam mold feeding device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foam mold feeding device, comprising a shell, a discharge pipe is arranged at the bottom of the shell, a feed pipe is arranged at the top of the shell, an air pipe is arranged at the top of the shell, an engine is arranged at the top of the shell, the output end of the engine is fixedly connected with a rotating shaft, the outer surface of the rotating shaft is fixedly connected with a stirring blade, a dispersion device is arranged at the top of the inner wall of the shell, the dispersion device includes a collecting piece, the top of the inner wall of the shell is fixedly connected with a collecting piece, a slider is arranged at the bottom of the collecting piece, a connecting rod is hinged at the bottom of the slider, a dispersion block is hinged at one end of the connecting rod away from the slider, the dispersion block is arranged as a special-shaped block, and the dispersion block is composed of a cylinder and a cone, and the arc-shaped outer surface of the dispersion block is fixedly connected with a guide.

[0007] Preferably, the guide members are arranged in a fan shape, the number of the guide members is four, and the four guide members are evenly distributed on the outer surface of the dispersion block in a circular array, and the guide members and the connecting rods are staggered, which can enable the guide members to better guide the materials.

[0008] Preferably, the collecting member is arranged in a truncated cone shape, with the small diameter end of the collecting member arranged downward, and the position of the collecting member corresponds to the position of the feed pipe, which enables the collecting member to effectively accelerate the speed at which the material enters the shell.

[0009] Preferably, the position of the dispersion block corresponds to the center of the collecting piece, and the size of the dispersion block matches the size of the collecting piece, which enables the dispersion block to better disperse the material.

[0010] Preferably, a slide groove is provided at the bottom of the collecting member, a sliding block is provided inside the slide groove, and a guide plate is fixedly connected to one side of the connecting rod close to the inside of the collecting member.

[0011] Preferably, the size of the slide groove is matched with the size of the slider, the guide plate is arranged at an angle, and a semicircular cylindrical protrusion is arranged on the upward side of the guide plate.

[0012] Compared with the prior art, the utility model provides a foam mold feeding device having the following

[0013] Beneficial effects:

[0014] 1. In order to prevent the material from sticking together after entering the shell and thus being difficult to transport, the raw material is expanded into granular material by the steam pre-foaming machine, and then enters the shell through the feeding pipe for storage. The material will first enter the collecting piece through the feeding pipe. The collecting piece is arranged in a truncated cone shape, and the small diameter end of the collecting piece is arranged downward, so that the material can be transmitted faster when passing through the collecting piece. When the material comes out of the collecting piece, it will contact the dispersion block. The dispersion block is a special-shaped block, and the dispersion block is composed of a cone fixedly connected to the top of a cylinder. When the material contacts the top of the dispersion block, it will flow around, and when it contacts the two sides of the guide, the material will disperse inside the shell after moving a distance along the two sides of the guide, and then cooperate with the rotation of the stirring blade to prevent the material from sticking together inside the shell and blocking the discharge pipe.

[0015] 2. In order to achieve a better material dispersion effect, when the material comes out from the collecting part, it will contact the inclined guide plate, which will push the connecting rod to one side, so that the slider moves inside the slide, which will cause the dispersion block and the guide to rotate, so that the material can be better dispersed inside the shell after contacting the dispersion block and the guide.

[0021] In the embodiment of the utility model, a collecting piece 8 is fixedly connected to the top of the inner wall of the shell 1. The collecting piece 8 is truncated and arranged in a cone shape. The small diameter end of the collecting piece 8 is arranged downward. A slide groove 13 is provided at the bottom of the collecting piece 8. The size of the slide groove 13 is adapted to the size of the slide block 9. A slide block 9 is arranged inside the slide groove 13. A guide plate 14 is fixedly connected to the side of the connecting rod 10 close to the inside of the collecting piece 8. The guide plate 14 is arranged in an inclined manner, and a semicircular cylindrical protrusion is arranged on the upward side of the guide plate 14. The position of the collecting piece 8 corresponds to the position of the feeding pipe 2, which can enable the collecting piece 8 to accelerate the speed at which the material enters the shell 1. A slide block 9 is provided at the bottom of the collecting piece 8, and the bottom of the slide block 9 is hinged with A connecting rod 10 is hingedly connected with a dispersion block 11 at one end of the connecting rod 10 away from the slider 9. The dispersion block 11 is a special-shaped block and is composed of a cylinder and a cone. The position of the dispersion block 11 corresponds to the center of the collecting piece 8, and the size of the dispersion block 11 is adapted to the size of the collecting piece 8, so that the dispersion block 11 can better disperse the material. A guide member 12 is fixedly connected to the arc-shaped outer surface of the dispersion block 11, and the guide member 12 is fan-shaped.
