Description

Technical Field

[0001] The utility model belongs to the field of automobile door lock molds, in particular to an automobile door lock mold which is easy to demould. Background Art

[0002] The vehicle body refers to the portion of a vehicle used to carry passengers and cargo, and also refers to the vehicle as a whole. In some vehicles, the vehicle body serves as both the driver's workplace and the space for passengers and cargo. The vehicle body includes windows, doors, the cockpit, passenger compartment, engine compartment, and luggage compartment, while the door lock frame is part of the vehicle's door.

[0003] According to a Chinese patent with the announcement number "CN216369824U", a mold for producing automobile door locks is disclosed, which includes a fixed mold base and a movable mold base. The movable mold base is arranged directly above the fixed mold base. A first mold placement groove is provided on the top of the fixed mold base. A lower mold core is provided inside the first mold placement groove. A clamping block and a handle are fixedly connected to the outer side of the lower mold core. A clamping groove and a receiving groove are provided on the side wall of the first mold placement groove. The clamping block is engaged with the clamping groove. The handle is arranged inside the receiving groove. A limiting mechanism is provided on the top of the fixed mold base. The limiting mechanism includes a limiting ring. The utility model splits the lower mold into the fixed mold base and the lower mold core, and splits the upper mold into the movable mold base and the upper mold core. Through the modular structural design, the lower mold core and the upper mold core can be quickly disassembled and assembled, and the fixed mold base and the movable mold base do not need to be changed. The upper mold core and the lower mold core can be replaced separately, and can be easily replaced after wear, which is conducive to extending the overall service life of the mold and thus reducing the maintenance cost of the mold.

[0004] According to the above structure, the lower mold is split into a fixed mold base and a lower mold core, and the upper mold is split into a movable mold base and an upper mold core. Through the modular structural design, the lower mold core and the upper mold core can be quickly disassembled and assembled, and the fixed mold base and the movable mold base do not need to be changed. The upper mold core and the lower mold core can be replaced separately. However, the above method cannot conveniently disassemble and demold the internal parts, which affects the production efficiency of the door lock and cannot help the model cool down quickly. After the mold is cooled, the molded part cannot be taken out quickly, which leads to a longer processing time for the entire mold, resulting in a waste of processing time. It is also possible that the operator will be scalded after demolding when the temperature is insufficient. Utility Model Content

Until the push plate 106 completely enters the bottom of the demoulding groove 101, the operating plate 108 also enters the bottom of the lower mold 5, and then the stamping process is also ended at the same time. Then, when demoulding, the hydraulic cylinder 6 is controlled upward to disengage the first contact rod from the second contact rod, so that the push plate 106 moves upward under the action of the lifting rod 105, the spring 109 and the tension spring 110, so that the operating plate 108 moves upward under the action of the operating rod 107. In the process of the operating plate 108 moving upward, The door lock parts inside the lower mold 5 are demoulded, and after the parts are stamped into the lower mold 5, the water pump 91 can be turned on so that the water in the water tank 95 enters the lower mold 5 through the water inlet pipe 96 under the action of the water pump 91, and then enters the drain pipe 97 through the lower mold 5, and then under the action of the water pump 91, the water enters the cooling box 93 through the first connecting pipe 92 for cooling, and then enters the water tank 95 again under the action of the second connecting pipe 94. After the water enters the interior of the lower mold 5, the lower mold 5 can be cooled. Before using the device, the electric push rod 14 is controlled to move the rubber pad 15 toward the inside of the shell 13. However, during the movement of the rubber pad 15, the air pressure at the bottom of the rubber pad 15 becomes smaller, thereby generating suction, so that the device can be firmly fixed.
