Description

Technical Field

[0001] This utility model relates to the field of vehicle lock processing technology, and in particular to automotive lock processing molds. Background Technology

[0002] Motor vehicle locks are crucial safety components for automobiles and other motor vehicles. They come in various types, primarily including mechanical locks (such as steering wheel locks, door locks, and trunk locks) and electronic locks (such as chip key locks, fingerprint locks, and proximity locks). Their structures and materials vary depending on the functional requirements of each lock. Machining molds, as the core tools for producing motor vehicle lock components, also come in several types, mainly including injection molds, stamping molds, and die-casting molds. Injection molds are mostly used to produce plastic casings and other components, stamping molds are primarily used for metal parts processing, and die-casting molds are commonly used for manufacturing high-precision metal parts. This diversity of mold types provides technical support for the mass production and efficient manufacturing of motor vehicle locks.

[0003] Stamping dies are primarily used in automotive lock manufacturing to produce metal parts such as lock cylinders, bolts, latches, spring clips, and decorative metal components. Through stamping, complex-shaped metal parts can be processed efficiently and precisely, meeting the stringent precision and strength requirements of locks. A stamping die consists of a die base, die cavity and core, guiding mechanism, unloading device, positioning device, and a cooling system designed as needed; its structure is precise and its functions are diverse. The die achieves high-precision machining of metal parts through processes such as forming, cutting, bending, and stretching. Stamping dies provide efficient and stable production support for fields such as automotive locks and are an indispensable key tool in mass production.

[0004] However, while existing mold designs can meet certain processing requirements, heat accumulation in the mold remains a persistent problem during prolonged, high-intensity processing. This can lead to excessively high mold temperatures, resulting in dimensional deviations in the processed parts, decreased surface quality, and shortened mold lifespan. Furthermore, traditional manual or simple mechanical unloading methods are inefficient and prone to problems such as uneven or damaged unloading of processed parts, thus affecting production efficiency and product quality consistency.

[0005] To address the above issues, a solution is proposed for machining automotive lock molds. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a processing mold for motor vehicle locks, which aims to solve the problems of excessive heat accumulation and low unloading efficiency of existing molds during the production process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a motor vehicle lock processing mold, comprising a base and an upper pressure plate, wherein hydraulic rods are provided at the four corners between the base and the upper pressure plate, an upper mold is fixedly connected to the bottom of the upper pressure plate, a lower mold is fixedly connected to the top of the base, an ejection mechanism is provided inside the base, and a cooling component is provided at the connection between the upper mold and the lower mold.

[0008] The ejection mechanism includes an outer frame, inside which a dual-head motor is installed. Both output ends of the dual-head motor are fixedly connected to turntables. Rotating rods are provided on opposite sides of the two turntables. The outer side of the rotating rods slides inside the slider. A push rod is fixedly connected to the top of the slider, and a limit plate is fixedly connected to the top of the push rod.

[0009] As a further description of the above technical solution:

[0010] The rotating rod is located off-center from the turntable, and the rotating rod moves in a circular motion around the center of the turntable.

[0011] As a further description of the above technical solution:

[0012] The top of the top rod extends through the top of the outer frame.

[0013] As a further description of the above technical solution:

[0014] The lower mold has two through holes inside, and the limiting plate is slidably connected inside the lower mold.

[0015] As a further description of the above technical solution:

[0016] A hydraulic device is provided on the upper pressure plate, and the protrusion of the upper mold is inserted into the recess of the lower mold.

[0017] As a further description of the above technical solution:

[0018] Both sides of the top of the lower mold are fixedly connected to fixing blocks.

[0019] As a further description of the above technical solution:

[0020] The cooling assembly includes multiple cooling pipes, and multiple cooling holes are provided inside the two fixed blocks, with the cooling pipes inserted into the cooling holes.

[0021] As a further description of the above technical solution:

[0022] The end of the cooling pipe can be connected to a coolant pipe or a cold air pipe.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, an automatic ejection mechanism is set in the base. After the sheet is processed, the double-head motor is started, and the ejector rod and the limiting plate are adjusted through reciprocating motion to eject the workpiece from the inside of the lower mold. This quickly and accurately ejects the workpiece from the mold cavity, improving production efficiency, reducing manual intervention, and reducing the probability of damage to the product surface caused by improper unloading.

[0025] 2. In this utility model, a cooling pipe is set at the pressure junction of the upper and lower molds, and the temperature can be controlled by coolant or cold air, which can effectively reduce the heat accumulation of the mold during processing, improve the service life of the mold, and ensure the dimensional stability and quality consistency of the processed parts.
