Embodiment 1

[0038] A mold for manufacturing a door closer housing in this embodiment includes a movable template 10, a movable mold core 11 embedded in the movable template 10, a fixed template 23, a fixed mold core 24 embedded in the fixed template 23, and a reset rod 13. Push rod 18, guide column 12 and guide sleeve 26 connecting movable formwork 10, fixed formwork 23, main flow channel 19, shunt flow channel 20, slag ladle groove 21, horizontal core-pulling mechanism, longitudinal core-pulling mechanism and two symmetrical centers cavity, the reset rod 13 and the push rod 18 are installed on one side of the movable template 10, the main flow channel 19 is opened on the fixed mold core 24, and is located at the lower position in the middle of the two center-symmetrical cavities. There are two cavities in the auxiliary mold, and the production efficiency is improved under the condition that the production cost is basically unchanged, and the benefit can be increased by about 40%. The run...

Embodiment 2

[0047] The basic structure of a mold for manufacturing the door closer housing of this embodiment is the same as that of Embodiment 1, the difference is that the inclination angle of the inclined guide column 15 of the mold in this embodiment is 20.5°, and the side of the cavity is provided with a Mold slope, demoulding slope is 1.2°; in the method for manufacturing the door closer shell of this embodiment, the mold cavity is preheated, the preheating temperature is 275°C, the molten aluminum alloy liquid is injected, and the injection pressure The temperature is 135 bar, the speed is 4m / s, and the cooling time is 5s. The aging treatment is to heat the door closer shell 1 to 175°C, keep it warm for 2.5h, and then cool it in the air.

Embodiment 3

[0049] The basic structure of a mold for manufacturing the door closer housing of this embodiment is the same as that of Embodiment 1, the difference is that the inclination angle of the inclined guide post 15 of the mold in this embodiment is 21°, and the side of the cavity is provided with a knockout Mold slope, demoulding slope is 1.5°; in the method for manufacturing the door closer shell of this embodiment, the mold cavity is preheated, the preheating temperature is 350°C, the molten aluminum alloy liquid is injected, and the injection pressure The temperature is 140bar, the speed is 5m / s, and the cooling time is 6s. The aging treatment is to heat the door closer shell 1 to 180°C, keep it warm for 2 hours, and then cool it in the air.

Abstract

The invention discloses a mold for manufacturing a door closer housing and a method for manufacturing the door closer housing, belonging to the technical field of mold manufacturing. The invention includes a movable template, a movable mold core, a fixed template, a fixed mold core, a reset rod, a push rod, a guide post, a guide sleeve, two center-symmetrical cavities, a main flow channel, a runner channel, a slag ladle groove, and a horizontal core pulling Mechanism and longitudinal core-pulling mechanism, the runner is set on the fixed mold core, and connected with the main channel, the shape of the runner is a flat hourglass shape with a small middle and big ends, and the junction between the runner and each cavity is divided into Two slot gates, the slag ladle grooves are evenly distributed on the side of the cavity, the horizontal core pulling mechanism adopts the inclined guide column core pulling mechanism, and the vertical core pulling mechanism adopts the hydraulic core pulling mechanism. Through the mold for manufacturing the door closer housing and the method for manufacturing the door closer housing of the present invention, the production efficiency of the door closer housing is greatly improved, the benefit is obviously increased, and the yield is high. At the same time, the door closer housing has High strength and hardness.

Description

technical field [0001] The present invention relates to a mold and a method for manufacturing products using the mold, more specifically, to a die-casting mold for manufacturing a door closer housing and a method for manufacturing a door closer housing using the mold. Background technique [0002] The significance of the door closer is to automatically close the door, which can protect the door frame and the door body (smooth closing), and more importantly, the door closer has become a non-negligible executive part of the intelligent management of modern buildings, mainly used in commercial and public buildings objects, but there are also situations where it is used at home. They have many uses, the most important of which is to allow doors to close themselves, to limit the spread of fire and to ventilate buildings. The door closer housing is the main part of the door closer, usually formed by aluminum alloy die-casting, such as figure 1 and figure 2 As shown, there are ...
