Embodiment Construction

[0049] Figures 1 to 9 A resin molding machine is shown. Figures 1 to 2 are a front sectional view and a side sectional view showing a mold in an open state, respectively. image 3 and 4 Respectively, a plane view and a section view of the channel plate ( image 3 section IV-IV). Figure 5 and 6 is a schematic diagram showing a drive unit of the flow channel plate. Figure 7 This is an overview of the resin molding machine. Figure 8 (a) to (d) and Figure 9 (e) to (g) show a molding process using the mold.

[0050] In these figures, reference numeral 1 denotes a resin molding machine for producing an electronic component made of a thermoplastic resin or a thermosetting resin by injection molding.

[0051] The resin molding machine 1 has a fixed bed 1a on which a mold 4, a mold clamping unit 5, and a molding material delivery unit 6 are provided. The mold 4 includes a movable mold unit 2 and a fixed mold unit 3, The mold clamping unit 5 moves the movable mold unit 2 ...

Abstract

To provide a resin molding machine capable of reducing cost and capable of reducing cycle time and amount of residual material without requiring a residual material remover, the resin molding machine comprising a pouring tank (13a) communicated with a mold cavity (C) A fixed cavity plate (13), in which is formed a sprue bushing (16) for feeding a molding material into a sprue (16a) of the cavity (C) through the pouring trough (13a), arranged on A flow channel plate (20) between the fixed cavity plate (13) and the gate bushing (16), used for reciprocating the flow channel plate (20) in a straight line through a molding position A between the ejection positions B1 and B2 A cylinder unit (runner plate drive mechanism) (25), the push-out positions B1 and B2 are separated from the molding position A, the push-out position is used to push out residual materials, and a cylinder unit for pushing out residual materials at the push-out positions B1 and B2 is included. Push-out channel (residual material push-out mechanism).

Description

technical field [0001] The present invention relates to a resin molding machine in which a molding material such as a thermoplastic resin and a thermosetting resin is injected from a gate into a cavity through a pouring groove for producing a resin molded article such as a Electronic component. Background of the invention [0002] These resin molding machines typically employ a three-plate, pinpoint-slot mold. [0003] In this model, if Figure 11 and 12 As shown, a mold cavity 53 is formed between the upper surface of a fixed lower mold 51 and the lower surface of a movable upper mold 52 which moves vertically between open / closed positions of the mold. The upper mold 52 has a channel 55 and a pouring groove 54 communicating with the mold cavity 53 . A gate bush 56a which moves vertically and which includes a gate communicating with the runner 55 is provided on the upper surface of the upper mold. [0004] In order to produce a resin molded product using the above resin ...
