Definitions
- the present invention relates to a method of manufacturing an embedded member molded body in which an embedded member is disposed in a thermoplastic resin.
- a conventional method for manufacturing an embedded member molded body is to place a coiled coil as an embedded member in a mold and fill the gap between the inner surface of the mold and the coil with a reinforcing mat to support the coil. To do. Then, a reaction stock solution for performing reaction injection molding is supplied, and a polymerization reaction is performed in a mold (see, for example, Patent Document 1).
- Patent Document 1 Japanese Patent Laid-Open No. 10-315267 (Page 3, FIG. 2)
- the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a method for manufacturing an embedded member molded body that can easily support an embedded member. Means for solving the problem
- a gate that can be filled with a thermoplastic resin is formed, and a plurality of pins that penetrate the outside force to the inside can be withdrawn to the outside.
- a first step of heating the mold to a predetermined temperature a second step of supporting the embedded member in a predetermined position in the mold by supporting it with a pin including the upper side of the embedded member, and embedding from the gate
- the embedded member is held at a predetermined position in the mold by a pin, and thermoplastic resin is filled into the mold on the lower side of the embedded member and pressed against the upper pin.
- thermoplastic resin is filled into the mold on the lower side of the embedded member and pressed against the upper pin.
- FIG. 1 is a plan view showing a molded body of an embedded member manufactured according to Embodiment 1 of the present invention
- FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1
- FIG. 3 is a cross-sectional view taken along line ⁇ - ⁇ in FIG. Fig. 4
- Fig. 4 is an explanatory diagram showing the state in the mold of the portion corresponding to the section II II in Fig. 1
- Fig. 5 is the inside of the mold in the portion corresponding to the section II-II I of Fig. 1. It is explanatory drawing which shows the state of.
- an embedded member 2 having a coil body strength is disposed in a cavity 1 lc of a mold 1 made up of split parts la and lb.
- a gate Id that can be filled with thermoplastic resin is formed at the bottom of the mold 1.
- a plurality of pins 3 penetrating inward and outward are arranged on the upper and lower sides and the left and right sides including the upper side so that they can be withdrawn.
- the embedded member 2 is supported by a pin 3 including the upper side of the mold 1 via a protective body 4 such as an insulating member, and is held at a predetermined position in the cavity lc of the mold 1.
- Each pin 3 that supports the embedded member 2 is fixed by a fixing means not shown in the figure.
- the mold 1 is heated to a predetermined temperature, and the embedded member 2 is disposed in the cavity lc.
- the embedded member 2 is supported by the upper, lower, left and right pins 3 including the upper side of the embedded member 2, and the embedded member 2 is held at a predetermined position in the cavity lc.
- a thermoplastic resin at a predetermined temperature is filled into the cavity lc of the mold 1 from the gate Id arranged on the lower side of the embedded member 2 at a predetermined injection pressure.
- the embedded member 2 is pressed against the pin 3 disposed on the upper side of the mold 1 by the thermoplastic resin previously filled on the lower side of the cavity 1 c of the mold 1.
- thermoplastic resin is filled in the remaining part of the mold lc of the mold 1.
- the fifth step before the temperature decreases to a temperature at which the thermoplastic resin filled in the cavity lc solidifies and loses its fluidity, Take out the pins in order from the pin 3 arranged on the lower side of the mold 1.
- the removal of the pin 3 in the fifth step may be started during the fourth step depending on the filling amount and speed of the thermoplastic resin.
- the embedded member molded body 5 shown in FIG. 1 is taken out from the power mold 1 after a predetermined cooling time has passed.
- the embedded member molded body 5 manufactured as described above has a thermoplastic resin 6 coated on the outer periphery of the coil body with a predetermined thickness as shown in FIGS. 2 and 3 where the embedded member is shown as a coil body. .
- an insulating member such as silicone rubber (not shown) is filled to further improve the insulation.
- the thermoplastic resin 6 is filled in the lower side force mold 1 of the embedded member 2, and the embedded member 2 is pressed against the pin 3 disposed on the upper side of the mold 1 to easily support the embedded member 2 by removing the pins sequentially from the pin 3 placed on the lower side of the mold 1 before the plastic resin 6 is solidified and drops to a temperature at which it loses fluidity. Can be done.
- the pin 3 since the embedded member 2 is pressed upward by the thermoplastic resin 6 filled at a predetermined pressure on the lower side of the embedded member 2, the pin 3 may be taken out before the thermoplastic resin is solidified.
- the embedded member 2 can be prevented from moving in the direction of gravity.
- Embodiment 1 the same effect can be expected even if the embedded member 2 is an electric device other than the force coil body described for the coil body and other things.
- the protector 4 may not be disposed if the pin 3 is not likely to damage the embedded member 2 or a slight scratch is a problem as a product.
- the thermoplastic resin is first filled in the mold 1 on the lower side of the embedded member 2 from the gate Id, and the embedded member 2 is filled with the thermoplastic resin 6 on the upper side of the mold 1.
- the pin 3 is pressed, and the pins are sequentially removed from the pin 3 arranged on the lower side of the mold 1 before the thermoplastic resin 6 is solidified and falls to a temperature at which it loses its fluidity.
- the temperature sensor 7 such as a thermocouple disposed in the mold 1 in the vicinity of each pin 3 is used for the thermoplastic It may be configured to detect the temperature of fat 6. That is, as shown in FIGS.
- the temperature sensor 7 is placed in the vicinity of each pin 3 by being filled with the thermoplastic resin 6 with the embedded member 2 held in the mold 1 by the pin 3. so By detecting the temperature of the thermoplastic resin 6 in the vicinity of each pin 3 and sequentially taking out from the pin 3 in the vicinity of the temperature sensor 7 that detects a value close to the temperature at which the thermoplastic resin 6 is solidified and loses its fluidity. The pin 3 can be taken out in a timely manner as the temperature of the thermoplastic resin 6 decreases.
- a temperature sensor 8 such as a thermocouple is arranged on the pin 3 and the temperature of the thermoplastic resin 6 near each pin 3 is detected. Can be expected.
- FIG. 1 is a plan view showing a molded body of an embedded member manufactured according to Embodiment 1 of the present invention.
- FIG. 2 is a cross-sectional view taken along line II-II in FIG.
- FIG. 3 is a cross-sectional view taken along the line ⁇ - ⁇ in FIG.
