に塗布することが難しかった。When applying mold release agent to the mold in die casting,
Conventionally, spray application was performed using automatic spray equipment. Spray application using an automatic spray device can save labor, but since the release agent is simultaneously sprayed from multiple spray nozzles facing the mold cavity, the release agents may interfere with each other. Most of the mold release agent does not reach the cavity surface and scatters, resulting in a lot of waste of mold release agent, and at the same time, it is difficult to apply enough mold release agent to the narrow and deep four parts.

。The present invention has been made in view of the drawbacks of spray application using an automatic spray device, and includes a movable bottle that is installed so as to be retractable from the parting surface in or near the cavity, and a tip portion of the movable bottle. By forming a mold release agent injection port in the mold, it is possible to effectively spray the mold release agent onto the cavity surface of the mold without using an automatic spray device, and at the same time, it is possible to spray the mold release agent onto the cavity surface narrowly. To provide a die casting machine capable of sufficiently applying a mold release agent even if there are deep four parts.
以下、本発明実施の一例を図面に基づいて説明する。Hereinafter, an example of implementing the present invention will be described based on the drawings.

側面に離型剤噴射口（６）を開口形成するものである。The movable pin (5) may be a well-known extrusion pin, carrier pin, return pin, etc., or may be a dedicated movable pin for achieving the purpose of the present invention. The illustrated embodiment is an example in which an extrusion pin attached to an extrusion plate α0 is used as the movable pin (5). Then, this movable pin (5) is installed so that it can come out and go out from the cavity part (3) or the parting surface (4) in its vicinity, and a release agent injection port (6) is provided at its tip (5a). An opening is formed so that the mold release agent (a) can be sprayed from the mold release agent injection port (6) to the cavity portion (3) of both molds (1) and (2). That is, in the embodiment shown in FIGS. 1 to 3, the inside of the movable pin (5) is formed into a hollow shape to form a passage (7), and an injection pump (not shown) is installed in the passage (7). A release agent supply hose (8) is connected to the movable pin (5), and a release agent injection port (6) is formed on the circumferential side of the tip (5a) of the movable pin (5) by communicating with the passageway (7). It is something.

の周側面に開口形成し、その噴射方向はキャビティ部（
３）の形状に応じて適当に設定される。The release agent injection port (6) is located at the tip (5a) of the movable pin (5).
An opening is formed on the circumferential side of the cavity, and the injection direction is
3) is set appropriately according to the shape.

ることも可能である。In addition, when a return pin is used as the movable pin (5), for example, a release agent injection port (
6) may be formed as an opening, or a spray nozzle separate from the movable pin (5) may be attached to the tip of the movable pin (5).

ある。Further, in the embodiment shown in FIGS. 4 and 5, a mold release agent chamber (9) is formed in the mold (2), and a movable pin (5) is inserted into this mold release agent chamber (9). At the same time, a mold release agent supply hose (8) connected to an injection pump (not shown) is connected, and a groove-shaped mold release agent with a substantially concave cross section is provided on the circumferential side of the tip (5a) of the movable pin (5). A jet nozzle (6) is formed therein.

射口（６）から離型剤（イ）を噴射させればキャビテイ
面（４）に離型剤（イ）を噴射塗布することが出来る。In this way, the die-casting apparatus of the present invention has the movable pin (5) installed so as to be freely protrusive and retractable from the parting surface (4) in the cavity portion (3) or the vicinity thereof, and the tip portion (5a) of the movable pin (5). Since the mold release agent injection port (6) is formed in the mold, after the mold is opened and the product (b) is taken out, the tip (5a) of the movable pin (5) is inserted into the cavity (3) or its vicinity. If the mold release agent (A) is made to protrude beyond the parting surface (4) and is injected from the mold release agent injection port (6), the mold release agent (A) can be sprayed onto the cavity surface (4). I can do it.
従って、自動スプレー装置を使用せずとも金型のキャビ
テイ面に離型剤を塗布することが出来ると共に、キャビ
テイ面に狭くて深い凹部が有ってもそこに離型剤を確実
に十分塗布することが出来る。Therefore, the mold release agent can be applied to the cavity surface of the mold without using an automatic spray device, and even if there is a narrow and deep recess on the cavity surface, the mold release agent can be reliably applied sufficiently to the cavity surface. I can do it.

、経済的である。Moreover, since the mold release agent is injected from a place very close to the cavity surface, the mold release agents injected from each mold release agent injection port are less likely to interfere with each other. #) It is economical as there is no wasted cost of mold release agent.

る時間を短縮することが出来る分である。Furthermore, existing extrusion pins, carrier pins, return pins, etc. can be used as the movable pins that form the release agent injection port, which is convenient and can speed up the timing of spraying and sys-spraying with automatic spraying equipment, which improves overall efficiency. The casting cycle time can be shortened. In other words, yes. 5- If an ejector pin is used as the movable bottle, the ejector pin operates at the same time as the mold opens and extrudes the product, and the tip of the ejector pin protrudes from the cavity, making it difficult to remove the product. After this, the mold release agent can be injected from the mold release agent injection port immediately after the mold release agent is applied, thereby shortening the time from the product removal process to the spraying process.
よって、所期の目的を達成し得る。Therefore, the intended purpose can be achieved.
