FORCED EXTRACTION MOLDED ARTICLE, POLYARYLENE SULFIDE RESIN COMPOSITION, AND METHOD FOR PRODUCING FORCED EXTRACTION MOLDED ARTICLE
A forced extraction molded article that can prevent damage during forced extraction is provided. The force extraction molded article (1) is formed of a polyarylene sulfide resin composition so as to include a cylindrical portion, wherein the cylindrical portion (10) has at a forward end portion a bulge (11), and an inner surface including a step in the outer diameter direction at the forward end portion, a portion excluding the step has a gradient such that the inner diameter of the cylindrical portion increases toward the forward end portion, and equation (a) below using a thickness D2 between a connection portion at the step on the inner surface of the cylindrical portion and the outer surface excluding the bulge, a height D4 of the step, and a height Dt of the gradient excluding the step on the inner surface of the cylindrical portion is satisfied.
Sealing cover and molding method thereof
Provided is a molding method of a sealing cover, realized by setting up a sealing cover mold, the mold includes a cavity and a core group arranged in the cavity, including setting up a first core and a second core, the mold opening direction of the first core and the second core are not parallel. The present application does not need a process hole to perform the injection molding of the sealing cover with a fastening structure, whose sealing is also better.

Gas cell housing molding mold, method for manufacturing gas cell housing, gas cell housing for gas sensor, and gas sensor including same
A gas sensor includes, in a single housing section, a substrate mounting surface 31 mounted with a substrate including a light emitter and a light receiver and a mirror section including plural reflectors. Then, in the housing section, all of the plural reflectors are integrally molded on an inner surface of the housing section to multiple reflect light emitted from the light emitter and cause the light to enter the light receiver in an opposing direction of one side and the other side in an extension direction of the substrate mounting surface.

Injection molding method for degradable intravascular stent with flexible mold core structure
Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing; Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.
Injection mould for producing complex moulded parts from plastic
An injection mould having a first mould half (17) and a second mould half (18) which can be displaced relative to the first in a first direction (z). At least one of the mould halves has a slider arrangement (1) for forming a mould cavity (15). The slider arrangement (1) includes at least two sliders (2) which are moveable relative to one another between a closed and an open position and which are arranged so as to be displaceable with respect to a component (3), adjacent to the sliders (2), of the associated mould halves (17, 18) by means of first and second guide means (6, 7) respectively. A slider drive (4) is used to displace the sliders (2) between the open position and the closed position.
METAL RIB OVERMOLDING JOINING
Metal rib overmolding joining including creating geometrical features in reinforcements for interconnecting a three-dimensional metal reinforcement to a metal base plate of an overmolding part in order to transfer load forces. Interlocked reinforcement is pre-assembled or assembled in an injection molding tool. Geometric features are positioned and joined creating a connection geometry that is overmolded. The joints created between the metal reinforcements are done without a welding process.
