Abstract

PURPOSE:To prevent a molded part from deforming owing to the difference in shrink which develops between inserts and a base after molding by a method wherein the inserts and the base are cut off each other after the inserts are fixed to the predetermined positions in a molding die and before resin molding is performed. CONSTITUTION:First, an insert plate 13 is inserted in a resin molder in such a manner that each insert 12 is set by arranging the horizontal part of the insert plate to grooved parts 23. Secondly, molds are clamped. Thirdly, a cutter 25 descends so as to cut a base 11 off inserts 12, 12,... at the edge 11a. Fourthly, resin material is fed in a cavity 22 in order to mold a resin part 14. Finally, after the molds are opened, runners are cut off in order to obtain a resin molded part, in the resin part 14 of which the inserts 12, 12,... are integrally imbedded. In addition, the above-mentioned molding is especially suitable for molding parts in continuous lengths.

The insert plate (3) integrally formed with... is used because a plurality of inserts (2) (
2)... can be set correctly at one time, which is extremely effective in improving work efficiency and maintaining accurate setting positions. However, the molded product (5) after molding rapidly shrinks at a higher shrinkage rate than the substrate (1) in which the resin part (4) is made of metal as it cools. may be deformed. In particular, if the molded product (5) has an elongated shape as shown in the figure and has a substrate (L) on one side along its length, it may be deformed as shown in Figure 5 or even perpendicular to the plane of the paper. Deformation, including directional warping, is likely to occur, so if the substrate (1) is of such a shape that is easily deformed, if the substrate (1) is not separated quickly after molding, a large number of deformed defective products will be produced and the yield will be reduced. Further, in order to perform the separation in a hurry, there are other problems such as constraints on the layout of the process, making it difficult to design the entire device.

An insert plate is manufactured in which the inserts are integrally formed in a predetermined mutual arrangement,
By inserting this insert plate into a resin molding machine and clamping the mold, each insert is fixed in a predetermined position in the mold, and the cutting blade attached to the mold is used to cut the space between each insert and the substrate. The substrate is removed by cutting it off, and then a resin material is supplied into a molding die to perform resin molding.

る。<Effects of the Invention> -1- As is clear from the description of the embodiments described above, in the present invention, after each insert is fixed at a predetermined position in a molding die, each insert and a substrate are bonded together before resin molding. In order to easily and correctly set multiple inserts in the mold, an insert plate with a shape in which multiple inserts are integrally formed on the substrate is used. There is no possibility that deformation stress will be generated later due to the difference in shrinkage rate between the substrate of the insert plate and the resin portion. Therefore, even if the shape is easily deformed, such as a long product, there will be no deformation, and the yield can be greatly improved. Also, there is no need to quickly separate the substrate after molding, so the manufacturing equipment can be improved. There are advantages that it is easy to design, and it is easy to obtain a device with a rational layout that is easy to work with.
