Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold that facilitates the ejection of a riser sleeve. Background Art

[0002] Riser refers to the supplementary part added on the top or side of the casting to avoid defects in the casting. Function In the casting, the cavity of the riser is the cavity for storing liquid metal. It supplies metal when the casting is formed, and has the functions of preventing shrinkage, shrinkage, exhaust and slag collection. The main function of the riser is to compensate for shrinkage. The design function of the riser is different. The form, size and opening position of the riser are different.

[0003] For example, a metal mold casting mold with a publication number of CN220127543U includes a cavity and a riser, one side of the riser is connected to the cavity, and the other side of the riser is connected to the external environment through an exhaust hole, and the inner wall of the cavity and the inner wall of the riser are both attached with a thermal insulation asbestos coating. With the technical solution of the utility model, the riser is only connected to the external environment through an exhaust hole with a limited diameter, and an inert gas can be fed through the exhaust hole to remove oxygen in the cavity, so that the molten magnesium alloy liquid is condensed in an inert gas protection atmosphere, which can prevent the molten magnesium alloy liquid from being oxidized or ignited, and improve the inclusion defects of the magnesium alloy casting. The riser also forms a replenishment effect on the molten magnesium alloy liquid during the condensation process, which has the effect of preventing the casting from generating shrinkage cavities, shrinkage and slag collection defects. In addition, the thermal insulation asbestos coating slows down the condensation and heat dissipation speed of the molten magnesium alloy liquid, avoids the defects of cold shut and undercasting easily generated in the magnesium alloy casting, and further improves the molding quality of the magnesium alloy casting.

[0004] However, according to the working principle proposed in the above patent, the applicant believes that although the above device can achieve a certain degree of molding quality, in actual use, the above device lacks an effective solution for removing the riser sleeve, which is easy to affect the efficiency of the mold when used.

[0005] Therefore, in view of the above problems, a mold is proposed which is convenient for ejecting the riser sleeve. Utility Model Content

[0006] The technical problem to be solved by the utility model is that: the prior art has the disadvantage that it is difficult to take out the riser sleeve, so we propose a mold that is convenient for ejecting the riser sleeve.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a mold for convenient ejection of a riser sleeve, comprising an upper mold base; a feeding tube is fixedly installed on the inner side of the upper mold base, a limiting tube is fixedly installed on the bottom of the inner cavity of the feeding tube, an electromagnetic rod is fixedly installed inside the limiting tube, a sleeve ring is fixedly installed on the top of the electromagnetic rod, a magnetic rod is movably installed on the inner side of the sleeve ring, a top ring is fixedly installed on the top of the magnetic rod, a material guiding cone tube is fixedly installed on the bottom of the top ring, a first limiting soft ring is arranged on the surface of the top ring, and a second limiting soft ring is arranged on the top of the inner surface of the feeding tube.

[0008] Preferably, an upper extension plate is fixedly mounted on the outer side of the upper die base, and a hydraulic telescopic rod is fixedly mounted on the surface of the upper extension plate.

[0009] Preferably, the top of the hydraulic telescopic rod is fixedly connected to a top plate, and support columns are fixedly installed around the bottom of the top plate.

[0010] Preferably, a bottom plate is fixedly mounted on the bottom of the support column, and a lower mold base is fixedly mounted inside the bottom plate.

[0011] Preferably, a lower extension plate is fixedly mounted on the outer side of the lower die base, and a supporting leg is fixedly mounted on the bottom of the base plate.

[0012] Preferably, a feed pipe is fixedly mounted on the bottom of the lower die base, and a connecting flange is fixedly mounted on the top of the feed pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a combination of a top ring and a material introducing cone tube, which are combined into a riser sleeve, so that the user can use the riser sleeve to supplement the material for the mold into the mold. A magnetic rod is installed at the bottom of the top ring. When the riser sleeve is in use, the magnetic rod is first aligned with the position of the sleeve ring inside the feeding tube, and then it is pressed downward. The first limiting soft ring and the second limiting soft ring are both lightweight and soft materials, and only a force greater than gravity needs to be applied to them to press them down or eject them. In the conventional installation completed state, the riser sleeve can be limited in position by the limiting soft ring and will not be ejected at will. Through the setting of the electromagnetic rod, the magnetic force formed after the electromagnetic rod is energized repel the magnetic force of the magnetic rod.
