Description

Technical Field

[0001] The utility model relates to the technical field of automobile unlocking handles, in particular to an automobile door emergency unlocking handle mould. Background Art

[0002] The emergency door unlock handle is usually located inside the car door, near the door handle. This handle is usually a small folding lever or button used to manually unlock the car door in the event of an emergency inside the car. It may be red or a striking color to make it easy to identify in an emergency. Pulling or pressing the handle will unlock the door, allowing passengers to quickly escape the vehicle. The emergency door unlock handle is usually manufactured by injection molding or die casting. First, the mold of the handle is made according to the design requirements. The mold is usually made of metal or plastic with the required shape and size. The handle material is then melted and injected into the mold for injection molding.

[0003] For example, the Chinese patent "A Automobile Door Handle Mold" with announcement number CN220163152U includes a lower module and an upper module, and the two opposite side walls of the lower module are protruding with protruding seats, and the inner cavities of the two protruding seats are formed on their top walls. Hydraulic telescopic rods are vertically installed in the two protruding seats, and the tops of the two hydraulic telescopic rods are connected to ear plates, and the two ear plates are symmetrically welded to the two ends of the upper module. A plurality of model grooves distributed in a linear array in the horizontal direction are formed on the top wall of the lower module, and the bottom wall of the upper module is fixedly connected with top sealing plates corresponding to the plurality of model grooves one by one, and one side wall of the lower module is connected to a cold water pool. A water pump is horizontally arranged on the upper side, wherein both ends of the water pump are respectively connected with an input pipe and an output pipe, the end of the output pipe away from the water pump is connected with a water collecting tank, and the water collecting tank is welded to the side wall of the lower module, a plurality of cooling pipes in communication with the water collecting tank are horizontally buried inside the lower module, the other side wall of the lower module is connected with a hot water pool, the inner cavities of the cold water pool and the hot water pool are both opened on the top wall thereof, a horizontal side plate is welded to the side of the inner cavity of the cold water pool facing away from the lower module, wherein the water pump is fixedly mounted on the horizontal side plate, a plurality of the cooling pipes and a plurality of the model slots are cross-distributed in a horizontal direction, and a plurality of the cooling pipes have one end away from the water collecting tank passing through the lower module and being placed above the inner cavity of the hot water pool.

[0004] Although the above-mentioned prior art can realize the production of emergency unlocking handles for automobile doors, in actual use, on the one hand, the cooling effect of the mold is not good enough. When the handle is cooled after it is produced, it is cooled through a cooling pipe, which leads to a slow cooling rate of the handle, thereby reducing the engineering efficiency. On the other hand, it is difficult to demold the handle after it is produced. When demolding the handle, the operator needs to take out the handle, which makes it difficult to take out the handle that is in contact with the inner wall of the fixed mold groove at one time, thereby affecting the production of the next batch of handles. Therefore, it does not meet the existing needs. In this regard, we propose an automobile door emergency unlocking handle mold. Utility Model Content

[0005] The utility model aims to provide an automobile door emergency unlocking handle mold to solve the problems in the above background technology that the mold cooling effect is not good enough and the handle is difficult to demould after it is manufactured.

[0006] To achieve the above object, the utility model provides the following technical solution: an automobile door emergency unlocking handle mold, comprising a base, a cooling box is fixedly arranged at the middle position of the upper end of the base; and further comprising:

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can quickly cool down the fixed mold through the water pump and the cooling cavity. When the handle is cooled after casting, the water pump is turned on to draw the coolant and input it into the cooling cavity until the fixed mold is immersed in the coolant. At this time, the coolant flows into the interior of the fixed mold through one end of the cooling hole on the fixed mold and flows out from the other end of the cooling hole. At this time, the coolant with a lower temperature absorbs the temperature on the fixed mold to reduce the temperature of the handle in the fixed mold. At this time, the coolant that absorbs heat is discharged from the interior of the cooling cavity through the water outlet, which accelerates the cooling rate of the fixed mold, thereby improving the engineering efficiency.

[0016] 2. The utility model can quickly remove the handle from the fixed mold groove through the electric push rod and the ejector block. When the handle is cooled, the electric push rod is turned on, so that the telescopic end of the electric push rod moves upward and drives the ejector block to move upward. The ejector block extends from the ejection cavity and ejects the upper end of the handle from the fixed mold groove through the ejector block. At this time, the operator removes the handle from the fixed mold groove, which speeds up the removal rate of the handle, thereby speeding up the production of the next batch of handles.

[0017] 3. The utility model can quickly fix the fixed mold through the fixing ring and the clamping block. When making the handle, the fixed mold that matches the handle of different shapes is aligned with the opening of the cooling cavity, and then the fixed mold is pushed into the cooling cavity until the clamping block outside the fixed mold abuts against the upper end of the fixing ring. The fixed mold is fixed in the cooling box by clamping the clamping block and the fixing ring. At this time, the fixed mold is inside the cooling cavity, so that the cooling box can fix the fixed molds of different handles, thereby improving the adaptability of the cooling box to handles of different shapes.
