A corresponding core shooting tool is further described.

A core molding apparatus and a core molding method capable of reducing the possibility of the deterioration in the calculation accuracy of the amount of supply of a raw material for a core are provided. A core molding apparatus includes: a kneading tank configured to knead a raw material for a core; a raw material supply unit configured to supply the raw material to the kneading tank; a mold configured to contain a kneaded material made of the raw material kneaded in the kneading tank and to mold the core; a piston configured to inject the kneaded material contained in the kneading tank into the mold; and a control unit configured to control an amount of supply of the raw material from the raw material supply unit to the kneading tank.

A core quality estimation system that estimates quality of a core to be formed by filling a mold with kneaded sand produced by kneading in a kneading tank and heating the kneaded sand includes a computer that executes operations of acquiring mold temperature information of the mold, acquiring environmental information regarding a surrounding environment in which the core is formed, and estimating the quality of the core based on the mold temperature information and the environmental information.

A plurality of upper fins and a plurality of lower fins are each provided in an EGR passage so as to be adjacent to each other across a predetermined space in a direction perpendicular to an exhaust-gas flow direction. The upper fins and the lower fins are gradually narrowed in width toward their respective projection directions, so that both sides thereof in their width direction have inclined surfaces. A tilt angle of the inclined surfaces of the lower fins is made larger than a tilt angle of the inclined surfaces of the upper fins.

The present disclosure relates to a display device. A downward-bending portion is formed on an end of an inner plate arranged on the inner surface of a back cover, which is a back support structure of the display device, such that the outer surface of the downward-bending portion contacts the inner surface of the back cover, thereby improving the rigidity and heat-radiating performance of the inner plate, and guaranteeing that the elastic force from the downward-bending portion prevents the display panel from being damaged by cracks. Furthermore, an inward-bending portion is formed on the front end of the vertical extension portion of the back cover, thereby improving the rigidity of the back cover, and guaranteeing that elastic deformation of the inward-bending portion protects the display device from lateral impacts.

The invention names a method for producing a lost casting core (G), which has a side surface (S1, S2), in a core box (1) that is divided into two core box parts (2, 3) in a parting plane (T), and which box delimits a mold cavity (8) in which an inner surface (14, 15) that reproduces the side surface (S1, S2) of the casting core (G) is provided, through which surface the parting plane (T) of the core box (1) runs. To prevent a burr in a critical section of the side surfaces (S1, S2) of the casting core (G), the following work steps are carried out: (a) producing a casting core insert (E) having a side surface section (SF1, SF2) that is equal to a corresponding section of the side surface of the casting core (G), from a casting core molding material (F); (b) positioning the casting core insert (E) in the mold cavity (8) of the core box (1) in such a manner that the side surface section (SF1, SF2) of the casting core insert (E) sits in the place of the corresponding section of the side surface (S1, S2) of the finished casting core (G), wherein the parting plane (T) runs through the side surface section (SF1, SF2); (c) introducing a casting core molding material (F) into the mold cavity (8) of the core box (1), so as to form the remaining casting core (G), wherein the introduced casting core molding material (F) comes into contact with the casting core insert (E); (d) solidifying the casting core molding material (F), thereby forming a shape-fit and/or material-fit connection between the introduced casting core molding material (F) and the casting core insert (E).

An insulated exhaust port liner of a cylinder head assembly for fluidly connecting to an internal combustion engine of a motor vehicle includes a sealing layer. The sealing layer has a first surface defining a passage for fluidly connecting to the internal combustion engine and receiving exhaust gas. The sealing layer further includes a second surface opposite to the first surface. The liner further includes a thermal barrier layer coated onto the second surface of the sealing layer. The thermal barrier layer is a porous non-woven material for supporting the sealing layer on the cylinder head and reducing a transfer of heat from the sealing layer to the cylinder head.

A riser sleeve (1) for using when pouring metals into a casting mould includes a riser body (2). The riser body (2) includes a riser cavity (3) for holding liquid metal and a riser opening (4) for joining the riser cavity (3) to a mould cavity of the casting mould during the casting process. The riser cavity (3) has a greater diameter than the diameter of the riser opening (4) in at least one portion, the riser body (2) is made of an insulating and/or exothermic riser material. The riser body (2) is formed as a single piece, the riser opening (4) defines an axis (5), and the riser cavity (3) is asymmetric to the axis (5).
