[0002] The automotive radiator is a key component of a water-cooled engine cooling system. It cools the engine through forced water circulation and is a heat exchange device that ensures the engine operates continuously within its normal temperature range. The radiator water chamber is one of the main components of the radiator system, and it is typically manufactured using injection molding.

[0003] For example, a plastic injection molding mechanism for producing radiator water chambers, disclosed in CN211763137U, includes an upper top plate and a fixed base plate. Hydraulic cylinders are fixed to both sides of the top of the fixed base plate, and a fixed seat is fixed to the top of the fixed base plate between the two hydraulic cylinders. The top of each hydraulic cylinder is connected to a fixed groove on the upper top plate via a telescopic rod that passes through both ends of the fixed seat. A spring is fitted inside the fixed groove and outside the telescopic rod. In this invention, since the upper and lower modules are detachably fixed to the upper top plate and the fixed seat respectively by bolts, users can replace the upper and lower modules according to the required size and shape of the radiator water chamber, offering greater flexibility and applicability to different radiator water chamber injection molding applications while saving costs.

[0004] The above technical solution has some problems in practical application. After the water chamber is injection molded, manual intervention by staff is required to complete the demolding, which is inefficient.

[0005] Therefore, it is necessary to invent an injection molding equipment for automotive radiator water chambers to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-3 The shown is an injection molding equipment for a car radiator water chamber, including a fixed mold 1 and a movable mold 2. There are two movable molds 2, and the two movable molds 2 are respectively arranged on both sides of the fixed mold 1. Push plates 3 are arranged on both sides of the fixed mold 1.

[0022] Specifically, a movable arm 4 is fixedly installed on the inner side of the push plate 3, and one end of the movable arm 4 extends into the cavity inside the fixed mold 1. A connecting arm 5 is movably installed on one end of the movable arm 4 via a pin, and a movable rod 6 is movably installed on one end of the connecting arm 5 via a pin. The top end of the movable rod 6 is inserted into the middle of the top end of the fixed mold 1. A movable seat 7 is fixedly installed on the top end of the movable rod 6. A transmission rod 8 is movably installed on both sides of the movable seat 7 via pins. A slide rod 9 is fixedly installed on one end of the transmission rod 8. A slide rail 10 is fixedly installed on the top end of the movable mold 2. The slide rod 9 is slidably installed inside the slide rail 10. A telescopic air rod 11 is fixedly installed between the fixed mold 1 and the movable mold 2. The telescopic air rod 11 can adjust the position between the fixed mold 1 and the movable mold 2.

[0023] More specifically, both ends of the upper surface of the fixed mold 1 are fixedly provided with extension arms 12, which are configured as "L"-shaped structures. The bottom inner side of the extension arm 12 is fixedly provided with a pressure block 13. The outer side of the movable mold 2 is provided with a movable plate 14. The four corners of the inner side wall of the movable plate 14 are fixedly provided with push rods 15. The push rods 15 are inserted and installed in the middle of the movable mold 2. A spring is provided between the movable mold 2 and the movable plate 14. One end of the push rod 15 is fixedly provided with a top block 16, which is located inside the movable mold 2.

[0025] Working principle of this utility model:

[0026] When this device is in use, the fixed mold 1 and the movable mold 2 are closed. The molten raw material can be injected into the mold cavity between the fixed mold 1 and the movable mold 2 and formed in the mold cavity. After the product is formed, the telescopic air rod 11 drives the movable mold 2 to move, so that the movable mold 2 is separated from the fixed mold 1. During the movement, the movable mold 2 drives the slide rail 10 to move until the slide rod 9 moves to one end of the slide rail 10. At this time, the slide rail 10 can drive the slide rod 9 to move. The slide rod 9 pulls the transmission rod 8. The transmission rod 8 pulls the movable seat 7 diagonally downward. The movable seat 7 drives the movable rod 6 to move, so that the movable rod 6 moves downward. The movable rod 6 can drive the movable arm 4 to move through the connecting arm 5. The movable arm 4 drives the push plate 3 to move, so that the product is pushed away from the end face of the fixed mold 1. At the same time, during the movement of the movable mold 2, the movable plate 14 on its outer side is squeezed by the pressure block 13 and moves towards the movable mold 2. The movable plate 14 drives the top block 16 to move through the top rod 15, so that the product is separated from the end face of the movable mold 2, so as to achieve the effect of automatic demolding of the product.
