  • Patent number: 10131081
    Abstract: Because it is possible to cool down a column member at a higher speed than natural cooling, throughput can be improved further. Especially, when the tubular body M42 and the column part M43 are made of different metals and the column part M43 is pressed into the tubular body M42, a distortion will occur in the column member M42 and M43 and the top board M41 fixed to the column member M42 and M43 due to the difference in thermal expansion coefficients between them, but the cooling paths P1 and P2 can absorb a distortion caused by the difference in thermal expansion coefficients of these metals. In particular, when the top board M41 is used as a mold for resin molding, it is possible to perform resin molding precisely because distortion caused by the difference in thermal expansion coefficients does not easily occur.

As a result, a weld structure is obtained in which portions having a high welding strength are continuously formed over the whole periphery of the peripheral edge path (330).

  • Patent number: 7549207
    Abstract: A manufacturing method for an actuator including a casing and a housing. The method includes setting a metallic ring in a molding die; injection molding a first flange portion of the casing using one annular hooking piece of the metallic ring as a part of a surface of the molding die so as to outsert-mold the metallic ring on a molded surface of the first flange portion, the molded surface being opposite to a first connecting end surface of the first flange portion; engaging the first flange portion with a second flange portion of the housing so as to be opposed to each other; and applying force to bend the metallic ring to form an other annular hooking piece, thereby crimping and fixing the first connecting end surface of the casing with a second connecting end surface of the housing.

  • Patent number: 7504059
    Abstract: An apparatus for manufacturing products from material which is thermoplastically deformable, as from plastic, comprising:—a mold (2) with at least one mold cavity (3);—in the or each mold cavity (3) at least one slide (8);—movement means for moving each slide (8);—closing means for opening and closing the mold (2);—feed means for introducing, with the mold cavity (3) closed, said material in at least substantially plastic condition into the or each mold cavity; wherein the movement means (9) for moving the slide (3) are arranged for moving said slide forward at a relatively high speed relative to the movement speed of the mold parts upon opening and closing thereof, from a position at least partly retracted from the mold cavity, such that said material, as a result, is displaced in the mold cavity for obtaining the filling thereof, preferably at a speed high such that adiabatic heat development occurs in the or each mold cavity.

  • Patent number: 7482700
    Abstract: A technique of accurately recognizing a semiconductor device and of specifying a package type thereof. By forming, on the package surface, projections having a geometric pattern such as a circle pattern using an ejector pin and by judging only presence or absence of the circular projections using an image processor, it is possible to reduce a risk of recognition failure of the geometric pattern even if the pattern has some omission in the constitutive line thereof or has any addition of a new line. For example, when the circular projections are provided on the surface of a package, an image processor reads only presence or absence of the circular projections even if disconnection of the line or addition of a line should occur, and this allows the circular projections to be always read as being “present”.

  • Patent number: 7338627
    Abstract: The present invention provides an injection molding method which intends to lower a mold clamping force in view of both of a projected area of a molded article and an injection pressure, and contributes to an energy saving and a reduction in a cost of equipment and a manufacturing cost. In a cavity (13) formed in a metal mold (5) for an injection molding, there are arranged a first gate (21) injecting a first molten resin (101) anteceding in one end side (a charging start side) in a longitudinal direction, and a second gate (22) injecting a second molten resin (102) following in another end side (a charging finish side). The second molten resin (102) is newly injected from the second gate (22) before a fluid head portion of the first molten resin (101) injected from the first gate (21) reaches a position of the second gate (22).

The machine includes a carton erection station to receive and erect a carton and a direct injection molding station. The molding station has an internal mold tool for receipt of the carton, and an external mold tool set. The internal tool and external tool set are configured to receive and secure a portion of the carton therebetween and define a mold cavity with the portion of the carton disposed therein. The external mold tool set defines an opening for receiving a polymer injection system to inject polymer into the mold cavity. A closure is directly molded in place on the carton, with the polymer encapsulating the inner peripheral edge of the carton opening that is disposed within the mold cavity. The packaging machine also includes a filling station for filling the carton and a sealing station for forming a seal on the carton.
