摘要： PURPOSE:To prepare a reel hub excellent in roundness, by molding an intermediate ring shaped part surrounded by an inner annular part having a shaft hole and an outer annular part coming to the outer peripheral surface of the reel hub while simultaneously molding the inner annular part and the outer annular part to the inside and outside of said intermediate ring shaped part. CONSTITUTION:An intermediate ring shaped part 5 surrounded by an inner annular part 3 having a shaft hole 2 through which the reel shaft of a tape recorder is inserted and an outer annular part 4 coming to the outer peripheral surface of a reel hub 1 is at first molded by an injection molding method. In the next step, the intermediate ring shaped part 5 is withdrawn from a cavity for molding the intermediate ring shaped part in a state attached to a movable side mold and, after the movable side mold is rotated by 180 deg. around the central axial line of a mold splitting surface, the mold is closed to fit the intermediate ring shaped part in a cavity for molding the outer annular part and the inner annular part. In the next step, a resin is injected into said cavity to simultaneously mold the inner annular part 3 and the outer annular part 4 to the inside and outside of the intermediate ring shaped part 5.

摘要： PURPOSE:To obtain a reel hub having good roundness and a good flatness degree and capable of stably winding up a magnetic tape, by forming a recessed part to the outer peripheral surface of an inner annular part along the peripheral direction thereof by utilizing the molding contraction of a molding material while using the outer peripheral surface of the inner annular part as the one constitutional surface of a cavity during the molding of an outer annular part. CONSTITUTION:An inner annular part 3 is formed into a thin wall at the inner peripheral part thereof surrounding a shaft hole 2 and a thick wall at the outer peripheral part thereof. The molding of this inner annular part 3 is performed under a molding condition easily generating a sink mark such that injection pressure is low or holding pressure is low. When molding is performed under this condition, a recessed part 5 due to the sink mark is formed to the outer peripheral surface of the inner annular part 3 along the peripheral surface thereof and, subsequently, an outer annular part 4 is molded by using the outer peripheral surface of the inner annular part 3 as one constitutional surface of a cavity. The depth of the recessed part 5 is pref. about 0.05-0.2mm. and, when 0.05mm. or less, the outer annular part 4 is easily pulled off from the inner annular part 3 and, when 0.2mm. or more, inferiority such as short is easily generated on the inner annular part 3.

摘要： PURPOSE:To set up simply a clip, etc. onto the specified position of a molded product by a method in which a mechanical sticking means is arranged onto a mold with its head exposed, and this head is preliminarily covered with the recessed portion of a plastic molding, and then resin is poured under pressure and solidified, after the pressure contact of the splitmolds. CONSTITUTION:On one mold 31 of the molds 3 composed of split molds 31, 32, the cavity 33 into which a molding 10 may be inserted is provided, and on the other mold 32, the hole 34 into which the leg 22 of a mechanical sticking means such as a clip 20 is inserted, is provided. The head 23 of the clip 20 is exposed and its leg 22 is inserted into the hole 34 of the split mold 32. This head 23 is capped with the recessed portion 11 which is preliminarily engraved on the plastic molding 10. Simultaneously, the leg 22 of the clip 20 is press-fitted into the cavity 34 of the mold 32. Then, molten resin is poured under pressure into the recessed portion 11 and solidified, thereby setting up the mechanical sticking means such as a clip 20 onto the plastic molding 10.

摘要： PURPOSE:To simplify the integration process of a cut piece of a sheet plate and a resin by a method wherein the sheet plate continuously fed is cut with a cutting punch in an injection molding die and cut pieces integrated with a resin injected into the die. CONSTITUTION:A sheet plate 7 having a hole 7a formed beforehand is fed continuously into a cutting punch 5 of an injection molding die and the die is closed being cut so that cut pieces are set into a core (formed with cavities 5a and 9a) of the die. A resin 10 is injected about the cut pieces 7b to integrate the cut pieces 7a. After the solidification thereof, a compound injection molding finished is taken out of the die. This method eliminates the need for setting the sheet plate cut beforehand one by one as well as the need for reworking a part of the sheet plate after the integral molding.
摘要翻译：目的：为了简化片状切片和树脂的切割片的一体化处理，其中连续进给的片状板在注射成型模具中用切割冲头切割，并将切割的片与注入模具的树脂形成一体。构成：将具有预先形成的孔7a的板材7连续地供给到注射成型模具的切断冲头5中，并且切断模具，使得切割件被设置成芯部（形成有空腔5a和9a）死了树脂10围绕切割片7b注入以使切割片7a一体化。固化后，从模具中取出成型的复合注塑成型品。该方法不需要预先一次一个地设置板材切割，以及在整体成型后需要对片材板的一部分进行再加工。
