Door Silent Hinge Lost Wax Casting

Product Introduction

A door hinge is a device that allows a door to rotate open and close naturally and smoothly.

The door hinge includes: hinge seat and hinge body, one end of the hinge body is connected with the door frame through the mandrel, and the other end is connected with the door leaf; the hinge body is divided into two sections, one is connected with the mandrel, the other is connected with the door leaf, and the two sections The body is connected into a whole through the connecting plate, and the connecting plate is provided with a hole for adjusting the gap between the doors. Because the hinge body is divided into two sections, which are connected into a whole through the connecting plate, the door leaf can be removed for repair after the connecting plate is pulled down.

The door gap adjustment hole of the connecting plate includes a long hole for adjusting the gap between the upper and lower door gaps and a long hole for adjusting the gap between the left and right door gaps. The hinge can be adjusted not only up and down, but also left and right.

Select points

Door hinges are opened and closed more than 10 times a day on average in everyone's life, so the quality of a hinge depends on the performance of your furniture, and you need to pay great attention to choosing the hinge hardware in your home.

The quality of the door hinge can be distinguished from the following three aspects:

1. Surface

Check whether the surface material of the Door silent hinge lost wax casting is smooth. If you see scratches and deformations, it is produced with scrap (leftover material). This kind of hinge has an ugly appearance and makes your furniture lack grade.

2. Hydraulic performance

The key of the hinge is to act as a switch, so this is very important. The key is obtained from the damper of the hydraulic hinge and the assembly of rivets. The damper mainly depends on whether there is noise when opening and closing. If there is noise, it is a low-quality product, and the round speed is uniform. Is the hinge cup loose? If there is looseness, it proves that the rivets are not tightly riveted and are easy to fall off. Close it several times to see if the indentation in the cup is obvious. If it is obvious, it proves that there is a problem with the thickness of the cup material, and it is easy to "explode the cup".

3. Screws

Generally, the hinge comes with two screws, both of which are adjustment screws, up and down adjustment screws, and front and rear adjustment screws. Some new hinges also have left and right adjustment screws, which are so-called three-dimensional adjustment hinges. Generally, two adjustment positions are sufficient. Tips, use a screwdriver to adjust the upper and lower adjustment screws three to four times, then remove the screw, and check if the hinge arm is damaged, because the hinge arm is made of iron material, not as hard as the screw, easy to wear, and if the precision is not enough when the factory is tapping, it is easy to slip the wire, or it may not be able to be screwed. The front and rear adjustment screws are also tested.

Common types

1. Furniture hinge

According to different installation combinations, it can be divided into in-line type and self-unloading type; according to the opening angle of the door panel, it can be divided into 90 degrees, 100 degrees, 110 degrees, 180 degrees, 270 degrees, etc.; according to the different cabinet assembly requirements, it can be divided into full cover (straight plate) ) half cover (small bend) and no cover (big bend or embedded).

2. Bathroom cabinet hinge

The number of switches in the bathroom cabinet is as many as tens of thousands of times, and the quality of the door hinge is very important. The practice has proved that in terms of the nature of the use of the bathroom cabinet, in terms of the accuracy of the arrangement of the bathroom cabinet, and the weight of the bathroom cabinet door itself, the selection of the hinge is the most important. Hinges are what we commonly call hinges. During the frequent opening and closing of bathroom cabinet doors, the hinges are the most tested. Most of the hinges seen on the market are detachable and are divided into two parts: the base and the buckle. Hinges generally have two-point and three-point hinges, and three-point hinges are of course better. The most important thing is the steel used to make the hinge. If the choice is not good, after a period of time, the door panel may lean forward and close, slip shoulders and drop corners. Almost all bathroom cabinet hardware of major brands use cold-rolled steel, and its thickness and toughness are perfect.

3. Buffer hydraulic hinge

The buffer hydraulic hinge is designed to provide a hydraulic buffer hinge that utilizes the buffer performance of the liquid and has an ideal buffer effect. The utility model includes a support, a door box, a buffer, a connecting block, a connecting rod, and a torsion spring. One end of the buffer is hinged on the support; The piston rod of the buffer is hinged; the connecting block, connecting rod, support, and door box form a four-bar linkage; the buffer includes a piston rod, a housing, and a piston. There are through holes and holes on the piston, and the piston rod drives When the piston moves, the liquid can flow from one side to the other through the through hole, thus playing a buffering role.

Installation Method

1. Use 2 screws to install the hinge cup on the hinge hole of the cabinet door (usually the hole is opened in advance);

2. Install the hinged seat on the side panel of the cabinet;

3. According to the installation of the door hinge and the cabinet body, adjust the door hinge to achieve the most uniform gap between the cabinet door and the cabinet door;

4. Accurate up and down height adjustment can be realized through the height-adjustable hinge base;

5. After adjusting the gap, all the screw holes on the door hinge should be filled with screws to ensure the service life of the door hinge
