Embodiment Construction

[0042] Embodiments of the sensor for measuring the internal information of the mold of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Figure 1~Figure 5 Representing the mold internal information measuring sensor 100 of the first embodiment, figure 1 is a vertical cross-sectional view of the mold internal information measurement sensor 100, figure 2 is a sectional view of the sensor part body, image 3 is a partial cut-away top view of the sensor component, Figure 4 yes figure 1 right side view of the , Figure 5 It is a schematic sectional view showing the state of being mounted on a mold.

[0044] The mold internal information measurement sensor 100 of this first embodiment can be mounted on the movable mold 1 a (or the fixed mold 1 b ) of the mold. Therefore if Figure 5 As shown, the movable casting mold 1a is perforated to provide mounting holes 8 reaching the mold cavity 2 from the back thereof. A...

Abstract

Disclosed is a sensor which detects information from a die-casting mold and which determines the quality of a molded product. The sensor detects the gas pressure within a cavity by being provided with: a rod-shaped casing which can be attached to an attachment hole that is drilled on a molding die and that opens to the cavity; a porous filter which is disposed on the tip of the rod-shaped casing, has a tip surface that can conform to the mold cavity surface, and which can separate gas from a melt; an introduction chamber to which the cavity gas is introduced from the porous filter; and a gas pressure sensor which detects the pressure within the gas introduction chamber. The sensor detects the melt pressure within the cavity by being provided with: a pressure transmission rod which is inserted into the rod-shaped casing, can move along the axial direction thereof, and has a tip surface that can conform to the mold cavity surface; and a pressure sensor which faces the rear end of the pressure transmission rod and is fixed and held thereto. Moreover, the sensor detects the melt temperature within the cavity by being provided with a temperature sensor which is attached to a small hole formed on the center of the pressure transmission rod, and which comprises a thermocouple that has a detecting end disposed on the small hole on the side of the tip of the rod.

Description

technical field [0001] The present invention relates to detection of the resin pressure, gas pressure or temperature of the melt in the mold of a die-casting machine for pressurized casting of metal materials such as aluminum alloy and magnesium alloy, and the melt in a mold for resin molding to judge casting-resin molded products Qualified mold internal information measurement sensor. Background technique [0002] It is well known that the quality of die-cast products is affected by the injection speed and injection pressure when filling the mold with molten metal. In the injection process of filling the mold with molten metal in the die-casting machine, the molten metal is supplied to the plunger sleeve, and the plunger is driven at a low injection speed to prevent the molten metal from being entrained by air. until the plunger sleeve and part of the product liner are filled. Then, when the plunger moves to the position where the front end of the molten metal reaches the...
