個所で十分な密度が得られない。 When using known methods of manufacturing mold parts, there have long been problems both in achieving a high degree of compaction of the mold material within said mold part, which is necessary to maintain the stability of the mold, and in having a sufficiently high production rate. It is occurring. Particularly in the case of complex mold parts with protruding ribs, if the mold part is introduced under high pressure, turbulence will occur in certain parts of the mold cavity. This turbulence causes an irregular filling action and a concomitant non-uniform density of the molded part. Introducing the mold material under relatively low pressure undesirably increases the working cycle time and does not provide sufficient density everywhere in the mold part.
本発明の目的は、低サイクル時間を用いながら
安定した高密度の鋳型部品が得られる鋳型部品の
製造方法を提供することにある。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for manufacturing molded parts that provides stable, high-density molded parts while using low cycle times.

によつて上記目的を達成することができる。 According to the present invention, the mold chamber 8 has the press plates 11, 12 which are movable toward each other and the mold plates 9, 10 attached to the press plates 11, 12, and the funnel-shaped inflow portion 4 is provided below. A container 1 storing mold material 2 communicates with the mold chamber through a throat portion 4A of the inflow portion 4, and the mold material is filled into the mold chamber 8 through the funnel-shaped inflow portion 4. In order to do this, pressurized gas is injected onto the mold material 2 stored in the container 1, and another pressurized gas is injected into the throat 4A of the funnel-shaped inlet 4 to make the mold material 2 flow. A method for manufacturing mold parts using an automatic mold parts manufacturing apparatus that injects gas onto the mold material 2, in which the pressure of the gas injected onto the mold material 2 is detected, and the feedback control circuit 23 operates based on the detected pressure. The pressure of the gas injected onto the mold material 2 and the pressure of another gas injected into the throat 4A are adjusted continuously and in places according to the shape of the mold part to be molded, When filling the mold chamber 8 with the material 2, the vacuum source 1
6 suctions the gas in the "shadow area" 8a behind the protruding ribs, etc. of at least one mold plate 9 in the mold chamber 8 through the suction passage 14, and the pressure source 17 applies the vacuum when the mold part is peeled off. Source 16
The above object can be achieved by a method of manufacturing a mold part characterized in that pressurized gas is supplied into the mold chamber 8 through the suction passage 14 instead.

れた圧力値に基づいて調節することが可能であ
る。 The introduction of pressurized gas into the funnel-shaped inlet itself allows the mold material to be worked with from the outset with relatively high filling pressures without the risk of creating bridging conditions within the inlet. It is possible to obtain high packing densities and low cycle times. The flow in the funnel-shaped section ensures laminar flow conditions between the final parts of the filling since low friction occurs between the components of the mold material. Separate control of flow pressure and filling pressure can be adjusted based on pressure values that have been proven by testing to be optimal pressures when manufacturing molded parts of a given form.
従来知られている装置の場合、充填圧力と流動

部品の正確な形態に従つて圧力を変化させ得る可
能性がなかつた。 In devices known from the prior art, both the filling pressure and the flow pressure are controlled independently of the instantaneous pressure values above the feed and in the funnel-shaped inlet. That is,
There was no attempt to make a continuous adjustment according to the values actually present in the relevant area, and therefore no possibility to vary the pressure according to the exact form of the molded part to be produced.
また、本発明によれば、鋳型室は「かげ区域」
における幾つかの点において真空源に接続されて
おり、「かげ区域」は真空源と連通することが可
能である。 Further, according to the present invention, the mold chamber has a "shaded area".
The "shaded area" can communicate with the vacuum source at several points in the vacuum source.

型腔内の重要な「かげ区域」すなわち突出リブな
どの背後の区域にも真空が適正に作用するので、
鋳型材料を「かげ区域」へ良好に充填することが
できる。 In this way, on the one hand, the cycle time is shortened because a vacuum is applied within the mold chamber, and on the other hand, the vacuum also acts properly on important "shadow areas" in the mold cavity, i.e. areas behind the protruding ribs, etc. ,
The mold material can be filled into the "shadow area" well.

要な「かげ区域」に関して特に有用であり、鋳型
部品の「かげ区域」の剥脱が極めて容易になる。 When stripping mold parts, as proposed by the invention, an effective cleaning of the filter or nozzle, through which a vacuum is generated by engaging a pressure source instead of a vacuum source, is ensured. A suction passage can be used to introduce the through hole and the vacuum and pressure into the mold chamber. Moreover, pressure jets suitable for stripping are particularly useful with respect to the critical "shadow areas" mentioned above, which greatly facilitate stripping of the "shadow areas" of the mold part.

Pressurized air is injected into the cavity above the sand 2 through a ventilation channel 3 provided in the side wall of the container 1. In the illustrated embodiment, the sand flow is caused by air being supplied at high pressure from the supply duct 5 at the narrowed throat 4A of the funnel-shaped inlet 4 of the container 1, as indicated by the arrow and dashed line in the figure. , an air pocket and flow are provided just above the throat 4A of the inlet 4.

することができる。 In the embodiment shown, pressurized air is supplied to the container 1 via a control valve 20 and a variable restrictor 21, respectively, from a pressurized air container 6, which is supplied with pressurized air from a compressor through a valve 7. Then, the pressure in the cavity of the container 1 (above the molding sand 2) is detected by the pressure gauge 22, and the detected pressure is fed back to the control circuit 23, and the detected pressure value and the setting determined in advance by the test are fed back. The control valve 20 is continuously controlled by the control circuit 23 based on the pressure value. Also, the throat 4A
