せる機構等ある。Conventionally, a molding die for producing this type of molded product consists of a fixed mold plate, a movable mold plate, a plurality of side walls provided between them, and a movable mold plate inside the side wall, which is integrated with the movable mold plate. The mold consists of a core with an inclined mounting surface and a slide core that is engaged with the inclined surface of the core so as to slide on the inclined surface.This mold is used to mold a molded product with undercapsulation on the inner and outer surfaces. Mine core C heart! ! ! The mold must be removed from these undercuts by moving it inside and outside the sidewall (side wall type) Fi. Therefore, conventionally, the mechanism described below has been adopted as a mechanism for releasing from these undercuts. There is. That is,
The sidewall mold release mechanism has an inclined pin fixed to the fixed mold plate, and when the movable mold plate and sidewall move at the same time when the mold is opened, the sidewall is pushed outward by the inclined pin to release the mold. The cylinder that serves as the power source for moving outward and the tilting pin are attached to a fixed mold plate, and the tilting pin is used as a guide to release the mold.In this case, a mold plate is used that allows multiple sidewalls to be released from the undercuff simultaneously. In the mold, the number of cylinders used is smaller than the number of sidewalls, and the sidewalls are connected with connecting pins or interlocking plates, or a mounting plate and a movable mold plate attached to the movable die plate of the injection molding machine main body are used. A spacer is installed in between to create a space, and an extrusion plate that connects to the extrusion port +7 of the injection molding machine body and moves forward and backward is installed inside this space, and this extrusion plate is linked to a side wall having an inclined surface. There is a mechanism for extruding the extrusion plate and releasing the sidewall outward along the slope of the reinforcing frame on the outside of the sidewall.
コアの離型機構は前述したサイドウオールの離型機構と
同じよ−うに取付板と移動型板との間に押出板を設け、
この押出板とスライドコアとをリンクで連結し押出板を
押出すことによりコアの傾斜面を滑らせ離型させるよう
になっている。The core mold release mechanism is similar to the sidewall mold release mechanism described above, by providing an extrusion plate between the mounting plate and the movable mold plate.
This extrusion plate and the slide core are connected by a link, and by extruding the extrusion plate, the inclined surface of the core is slid and released from the mold.

に取付けの取付板と移動型板との間に押出板を設け、と
の押出板とスライドコアおよびサイドウオールの両方を
それぞれリンクで連結してサイドウオールとコアとを同
時に移動させるようにしたものである。The above-described mechanism for separating the sidewall and core from the undercarriage is employed, and most of its operations involve a single operation in which the core is moved after the entire sidewall has been moved. However, U.S. Pat. No. 3,905,740 provides an extrusion plate between a mounting plate attached to a movable die plate of an injection molding machine and a movable die plate, and both the extrusion plate and the slide core and sidewall are connected to each other. The sidewall and core are connected by links so that they can be moved at the same time.
従来の射出成形用金型は以上説明した構成となっている
ため、サイドウオールとコアとを個々に移動させる場合
、すなわち、サイドウオールを移動させた後コアを移動

する機構は押出板が進退するスペースが必要となり金型
全体が大きくなり重量が増すとともにリンク機構が複雑
で部品点数も多くなり故障が多く保守の面でも好ましく
ない等種々問題がある。Conventional injection molds have the configuration described above, so if the sidewalls and core are moved individually, that is, if the core is moved after the sidewalls are moved, the molding cycle becomes longer. Productivity drops and becomes a problem. Furthermore, if the sidewalls are not moved only by the tilt pins, excessive force is applied to the tilt pins and the mold opening speed must be slowed down, which is also undesirable as the molding cycle becomes longer. In addition, the mechanism connected by extrusion requires space for the extrusion plate to move forward and backward, which increases the size and weight of the entire mold.The link mechanism is complicated, the number of parts increases, and there are many problems such as failure and poor maintenance. be.
本発明はこれらの欠点を解消するために発明されたもの
で従来の金型に比較してより金型を小さくし重量を軽減

ことを目的とした射出成形用金型である。The present invention was invented in order to eliminate these drawbacks, and compared to conventional molds, the mold is made smaller and weighs less, increasing the cycle time, reducing the number of parts, reducing failures, and making maintenance easier. This is an injection mold that can be manufactured at a lower cost.

A plurality of side walls and slide cores can be moved simultaneously by connecting the side walls and the slide cores with a connecting member Ct;
This is a more compact mold.

It extends inward, and its tip is connected to the gate 7 located inside the fixed mold plate 2. The inside of the fixed mold plate 2 is a mold for molding the bottom surface of the molded product S and the outer surface of the side wall of the portion near the bottom surface. Two hydraulic cylinders 9 are installed diagonally to the movable mold plate 4 so as to pass through the movable mold plate 4 from the mounting plate 3 side and open from each other on the fixed mold plate 2 side. A nut 12 having a cylindrical shape and a headband-shaped center portion is screwed onto the tip of the rod 10 of each hydraulic cylinder 9, and a molded product 8 is inserted into the groove 1).
U-shaped notches 15 (see FIG. 9) of the side walls 13 and 14 are fitted to form the surfaces of the side walls (upper and lower surfaces in FIG. 2) of the hydraulic cylinders 90 and 10 when the hydraulic cylinders 90 and 10 move forward or backward. The walls 13, 14 are also adapted to move at the same time along the tilting pins described below. In addition, two sidewalls that are combined with sidewalls +3 and +4 to form the other two outer surfaces of the molded product 8 are provided, and these four sidewalls cover most of the outer surface of the molded product S. Four id pins penetrate the movable mold plate 4 from the mounting plate 3 side and protrude from the fixed mold plate 26m so as to form the mold.
The tips of these guide pins 15 fit into holes 16 at corresponding positions in the fixed mold plate 2 when the mold is closed. A core 17 having a trapezoidal cross section is fixed to the movable mold plate 4 by bolts 18 approximately in the center of the movable mold plate 4.

The mold is clamped by a mold clamping device of an injection molding machine (not shown), and molten resin is injected under pressure from the runner block 6 in the state shown in FIG. The injected resin is press-fitted from the gate 7 into the cavity in which the molded product 8 is to be molded, and is cooled to harden except for the runner block 6 portion. Next, the mold opens. First, as shown in FIGS. 7 and 8, the core 17 is placed on the fixed mold plate 2'1 and directly attached to the movable mold plate 4, the oilfield cylinder 9 and the side wall 13 connected by interlocking plates 26 and 27.
, I4.24.25 Furthermore, the slide core 1g, +9 connected by the connecting plate 29.30 moves to the left side together with the molded product 8. The state shown in FIG. 7 is that after the movable mold plate 4 has retreated to the retraction limit (moved to the left), the hydraulic cylinder 9 is actuated and the robot 1 is

8.19 is moved via the connecting plate 29.30e. The state shown in FIG. 7 has been explained assuming that the hydraulic cylinder 9 is activated after the movable mold plate 4 has retreated to the retraction limit, but it is also possible to operate the hydraulic cylinder 9 while the movable mold plate 4 is retracting. It is advantageous to adopt this method in order to shorten the operating cycle. Molded product 8t - The mold closing operation after removal is performed in the reverse order of mold opening.
