) and inject the resin (7) from the injection port (lc). At this time, the viscosity of the resin is 1000-20,000.
It is about CP. [Problems to be Solved by the Invention] In the conventional casting mold apparatus as described above, when casting, the spacer member (4) for positioning is required every time. (4)
... not only had to be glued to the iron core (3), but also because the fixing method was adhesive, the spacer member (
4). (4)... tends to become unstable, the spacer members (4>, (4)...) may come off, or the positioning accuracy is adversely affected, and the spacer members (4). (4) - When the adhesion of the interface between the metal resin and the metal resin is poor, there are problems such as water intrusion along the interface and flash failure.The present invention solves the above problems. It was created to enable conductors to be resin-sealed (molded) with high precision.
Another purpose is to provide a casting mold device that produces electrically superior electrical equipment. [Means for Solving the Problems] The casting mold device according to the present invention has a conductor attached to the upper mold in order to position the conductor in the upper mold on the lower mold by sliding it from the outside of the upper mold to the inside of the upper mold. It is equipped with a plurality of sliding and airtight positioning support members, and a suction means provided on the lower die to hold the conductor positioned by the support members at the position. [Function] In this invention, the conductor is positioned on the lower mold by the support member, and the conductor is held at the positioned position by the suction means, and in this state, resin is injected into the upper mold and the lower mold. It will be done. [Examples] Examples of the present invention will be described below. Figures 1 and 2
The figure is a vertical sectional view showing one embodiment of the present invention and its A.
- It is an Ali cross-sectional view, and the same or corresponding parts as in FIGS. 3 to 5 described above are given the same reference numerals, and their explanations will be omitted. In the figure, (10) is a support member that replaces the conventional baser, and the support member (10) is divided into two parts (la). (l
b) A plurality of molds are provided on each side and the top surface of the upper mold (1) and configured to be slidable from the outside of the upper mold to the inside of the upper mold,
and each support member (10) protruding from the outside of the upper mold (1).
and the end protruding into the inside of the upper die (1) are each provided with a strike bar (1) to prevent the support member (10) from coming off.
0a) and (Job) are formed, and the iron core (3) is pressed and supported by a stopper (10b) protruding inside the upper mold (1). (11) is a supporting member (10). A stopper (10b) that protrudes into the inside of the upper mold (1) when the upper mold (1) is slid to the outside of the maximum mold (<1)
is a recess formed in the inner wall of the upper mold so that it is flush with the inner wall surface of the upper mold (1), and (l2) is the sliding part 7 of the support member (10)! Inner t! Snow OL 10m or Shinkakuta Olling (IJ1t ÷ Lower part 2) Adsorption groove for fixing the iron core (3), (1
4) indicates a leak-preventing packing placed at the opening of the suction groove (13), and (15) indicates a vacuum communication hole formed in the lower mold to communicate with the suction groove; l3
) and the communication hole <15) constitute a suction means for the iron core (3).In the casting mold device configured as above, the upper mold (1)
After accurately positioning the iron core (3) placed on the lower mold (2) within the upper mold (11) using a plurality of supporting members (10) provided for the upper mold (1) and the lower mold (2), Bolt (5) ,
(6), the suction groove (13) formed in the lower mold (2) is evacuated and the iron core (3) is suctioned and held, and then each support member (10) is released and the support member (10) ) Pull out the stopper (tab) at the protruding end inside the upper mold to the inside of the four parts (1l), make sure that the support member (10〉) is not inside the upper mold (1), and then pour the synthetic resin from the injection port (lc). In the above embodiment, the vacuum suction means described as the suction means for holding the conductor {3> in the lower mold (2) is -ht.

Of course, if (3) is a magnetic material, it may be an electromagnet. [Effects of the Invention] As explained above, according to the casting mold device of the present invention, the conductor to be resin-sealed is positioned on the lower mold by the support member placed on the upper mold, and Since the conductor is held by the suction means configured on the lower mold, the conductor is sealed with resin with good accuracy, and the base material is not embedded in the synthetic resin that is the sealing material, so it is electrically superior. This has the effect of making it possible to obtain electrical equipment that can be used in a variety of ways.
