Abstract: The invention provides a split-type mold for wheel casting, the mold having an upper die, a split-type water-cooling side die and a lower die, and the split-type water-cooling side die is divided into four pieces along a circumferential direction of the wheel mold. A thermal deformation arc compensation surface is machined on ¼ arc portion of each split-type water-cooling lower side die, and a compensation surface is machined on key portions of 45-degree matching surfaces of adjacent split-type water-cooling upper side dies. The side die can effectively solve the problems such as untight matching between the matching surfaces, flashes of the matching surfaces and aluminum sticking and the like due to the thermal deformation and non-homogeneous expansion and shrinkage of the two portions of the split-type water-cooling side die.

Abstract: The present invention provides an integrated mold for casting of wheels. The integrated mold has an upper mold, integrated side molds and a lower mold, wherein the number of the integrated side molds is four in the circumferential direction of the wheel mold. Thermal deformation circular arc compensation surfaces are formed by processing on an upper and lower one-fourth circular arc part of each integrated side mold, and compensation surfaces are formed by processing on key parts of 45-degree matching surfaces of the adjacent integrated side molds. The integrated side molds can effectively solve the problems such as imprecise matching of the matching surfaces, parting-line flashes of the matching surfaces and adhesion of aluminum caused by thermal deformation of the integrated side molds.

Abstract: The present invention provides an integrated mould for casting of wheels. The integrated mould has an upper mould, integrated side moulds and a lower mould, wherein the number of the integrated side moulds is four in the circumferential direction of the wheel mould. Thermal deformation circular arc compensation surfaces are formed by processing on an upper and lower one-fourth circular arc part of each integrated side mould, and compensation surfaces are formed by processing on key parts of 45-degree matching surfaces of the adjacent integrated side moulds. The integrated side moulds can effectively solve the problems such as imprecise matching of the matching surfaces, parting-line flashes of the matching surfaces and adhesion of aluminum caused by thermal deformation of the integrated side moulds.

Abstract: A connecting assembly for connecting a first member and a second member, and the connecting assembly includes a resilient receiver and a securing plug. The second member defines a through hole. The resilient receiver is fixed to the first member and also defines a receiving space. A top of the resilient receiver passes through the through hole. The securing plug is configured to be inserted into the receiving space, which expands a part of the resilient receiver so as to fix the top of the resilient receiver on the second member thereby connecting the first member with the second member. Present disclosure also provides an electronic apparatus having the connecting assembly.

Abstract: A fastener includes a sleeve and a rod received in the sleeve. The sleeve includes a top end including at least one outer flange extending radially outward therefrom and at least one inner flange extending radially inward therefrom and a lower end including at least one spring tab. At least one spring tab comprises an outer flange at its end that extends radially outward. the sleeve is inserted into the receiving holes of the top article and the bottom article until the outer flange of the top end rests on the top plate, the rod is then pressed to move to drive at least one spring tab to deflect outwardly until the outer flange of at least one spring tab is held in contact with the bottom plate.

Abstract: A method for affixing adhesive films to a main board is provided. The main board includes a main body and a shield. The shield includes a first shield and a second shield. The second shield defines openings. When the second shield is attached to the main body, components of the main body are confined within the openings, respectively. The method includes: first absorbing a single adhesive film to an electrostatic absorbing film. Then, stamping the electrostatic absorbing film and the single adhesive film to form adhesive films that have substantially the same shape and arrangement as the openings. Next, aligning the electrostatic absorbing film with the first shield and affixing the adhesive films to the first shield. Then, removing the electrostatic absorbing film from the first shield. And, assembling the first shield to the second shield.

Abstract: An electronic device includes a housing and a button. The housing defines a through hole. The sidewall of the through hole defines a pair of positioning holes. The button includes a frame, a sliding bar assembly, an elastic conductive member, and a pressing member. The sliding bar assembly is received in the frame with two external ends respectively received in the positioning holes to cause the frame to be received in the through hole. The elastic conductive member is fixed in the housing. The pressing member hooks the frame and extends through the frame to resist the sliding bar assembly. When the pressing member is depressed, the pressing member resists the sliding bar assembly to cause the external ends to move out of the positioning holes. Further depress on the pressing member causes the frame to press the elastic conductive member to actuate the button.

Abstract: A switch assembly includes a cover, a main body, a base and a fixing member to connect the cover with the base. The cover is fixed to the base to define a space for the main body. Two switch elements are disposed apart from each other on the base. The main body includes two buttons connected by a connection element. The connection element includes a combination portion, two elastic arms and two connection portions. The combination portion is fixed to the base. The elastic arms extend respectively upwards from the combination portion. The elastic arms are respectively connected to one end of the connection portion away from the combination portion.
