[0002] In automotive parts manufacturing, gear chamber cover molds are key equipment for achieving efficient and precise manufacturing of gear chamber covers. They possess high wear resistance and good thermal stability, not only giving products precise dimensions, stable mechanical properties, and a smooth appearance, but also enabling large-scale, high-efficiency production with their excellent production capabilities, greatly reducing unit production costs.

[0003] Gear chamber cover molds are the core tools for mass production of gear chamber covers. Through the precise matching of the cavity and the core, plastic raw materials are uniformly filled and molded using processes such as injection molding, giving the product accurate shape and size, and ensuring that each cover meets the assembly precision requirements of automobile engines. However, when using existing gear chamber cover molds, the workpiece is usually removed from the mold. This process requires a certain amount of time and effort, resulting in long production cycles and low equipment utilization. Utility Model Content

[0004] The purpose of this utility model is to provide a gear chamber cover mold that facilitates demolding, in order to solve the problem that the existing gear chamber cover molds usually require a certain amount of time and effort to remove the workpiece from the mold, resulting in a long production cycle and low equipment utilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gear chamber cover mold that is easy to demold, comprising: a mold base, an upper mold mechanism provided on the outer side and top of the mold base, a receiving groove opened at the bottom of the inner side of the mold base, a return spring fixedly connected inside the receiving groove, a spring plate slidably connected to the inner side of the mold base, an inner lower mold box movably slidably connected to the top of the spring plate, a mold cavity opened at the top of the inner lower mold box, a pre-placement frame fixedly connected to one end of the upper part of the mold base, a tail support frame fixedly connected to one end of the upper part of the mold base, and a cooling mechanism provided on one side of the tail support frame.

[0006] As a further embodiment of this utility model: the upper mold mechanism includes an upper mold cover and a side support member. The upper mold cover is disposed on the top of the mold base, and the side support member is fixedly connected to one side of the upper mold cover; a mold core and a cylinder. The mold core is fixedly connected to the bottom of the upper mold cover, and the cylinder is fixedly connected to one end of the outer side of the mold base. The movable end of the cylinder is fixedly connected to the side support member.

[0007] As a further embodiment of this utility model: the cooling mechanism includes a support frame and a motor, the support frame being fixedly connected to the upper end of one side of the tail support frame, the motor being fixedly connected to one end of the support frame; a rotating shaft and a cooling fan, the rotating shaft being rotatably connected to the middle of the upper part of the support frame, the cooling fan being fixedly connected to one end of the rotating shaft, and the other end of the rotating shaft passing through the support frame and being fixedly connected to the output end of the motor.

[0008] As a further embodiment of this utility model: the other end of the reset spring is fixedly connected to the top plate, the inner lower mold box is movably inserted into the mold base, and the pre-placement frame and the tail support frame are both slidably connected to the inner lower mold box.

[0009] As a further improvement of this utility model: multiple sets of the receiving groove and the reset spring are provided, and the multiple sets of the receiving groove are symmetrically arranged at the bottom of the mold base.

[0010] As a further improvement of this utility model: two sets of the side support members and two sets of the cylinders are provided, with the two sets of the side support members symmetrically arranged on both sides of the upper mold cover, and the two sets of the cylinders symmetrically arranged on both sides of the mold base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the unused inner lower mold box is placed on the pre-placement frame. When demolding is required, the cylinder drives the side support to move, causing the upper mold cover to separate from the mold base. At the same time, the compressed return spring releases its elastic potential energy, and the spring plate pushes the inner lower mold box upward until it is level with the pre-placement frame and the tail support frame. This pushes the unused inner lower mold box to the top of the mold base, making it contact the inner lower mold box containing the workpiece and forcing it to move to the tail support frame. After the unused inner lower mold box reaches the top of the spring plate, the cylinder then drives the upper mold cover to press down, and the inner lower mold box enters the mold base. The return spring returns to its initial position, completing the demolding and preparing for injection molding. This method can automatically demold without manual tools, saving demolding time and increasing the output per unit time. Replacing the unused inner lower mold box can form a closed-loop process of "demolding-replacement-injection molding", significantly shortening the single production cycle. The inner lower mold box containing the workpiece on the tail support frame is rotated by a motor-driven shaft, causing the cooling fan to run and cool down, avoiding prolonged demolding time due to cooling inside the mold.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 5In this embodiment of the utility model, a gear chamber cover mold that is easy to demold includes: a mold base 1, which serves as the basic frame of the entire mold, provides a platform for the installation and support of other components, and ensures the stability of the relative positions between the various components of the mold; an upper mold mechanism 2 is provided on the outer side and top of the mold base 1; a receiving groove 3 is provided at the bottom inside the mold base 1; a return spring 4 is fixedly connected inside the receiving groove 3; the receiving groove 3 is used to accommodate the return spring 4 and provide a stable installation space for the return spring 4.

[0022] A spring plate 5 is slidably connected to the inner side of the mold base 1. An inner lower mold box 6 is movably slidably connected to the top of the spring plate 5. The return spring 4 is in a compressed state in the initial state. When it releases its elastic potential energy, it will push the spring plate 5 upward, thereby pushing the inner lower mold box 6 to move upward. A mold cavity 7 is opened on the top of the inner lower mold box 6.

[0023] A pre-placement frame 8 is fixedly connected to one end of the mold base 1 for placing the inner lower mold box 6 to be used. After demolding, the inner lower mold box 6 to be used can be moved from the pre-placement frame 8 to the top of the mold base 1 to realize the quick replacement of the inner lower mold box 6 and improve production efficiency. A tail support frame 9 is fixedly connected to one end of the mold base 1. During demolding, it is used to receive the inner lower mold box 6 containing the workpiece that is moved from the top of the mold base 1. A cooling mechanism 10 is provided on one side of the tail support frame 9. The other end of the return spring 4 is fixedly connected to the spring plate 5. The inner lower mold box 6 is movably inserted into the mold base 1. The pre-placement frame 8 and the tail support frame 9 are both slidably connected to the inner lower mold box 6. There are multiple sets of receiving grooves 3 and return springs 4. Multiple sets of receiving grooves 3 are symmetrically arranged at the bottom of the mold base 1.

[0024] Reference Figure 1 and Figure 4 The upper mold mechanism 2 includes an upper mold cover 201 and a side support member 202. The upper mold cover 201 is disposed on the top of the mold base 1, and the side support member 202 is fixedly connected to one side of the upper mold cover 201.

[0025] The mold core 203 and cylinder 204 are fixedly connected to the bottom of the upper mold cover 201 and the cylinder 204 is fixedly connected to one side of the mold base 1. The movable end of the cylinder 204 is fixedly connected to the side support 202. There are two sets of side support 202 and cylinder 204. The two sets of side support 202 are symmetrically arranged on both sides of the upper mold cover 201 and the two sets of cylinder 204 are symmetrically arranged on both sides of the mold base 1. The cylinder 204 drives the side support 202 to separate the upper mold cover 201 from the mold base 1. The reset spring 4 releases the elastic potential energy. The spring plate 5 drives the inner lower mold box 6 to be pushed up until it is flush with the pre-placement frame 8 and the tail support frame 9. The waiting inner lower mold box 6 is pushed to the tail support frame 9 and replaces the original inner lower mold box 6. The cylinder 204 reverses the action, the upper mold cover 201 is pressed down to reset, the inner lower mold box 6 returns to its position, and the demolding is completed.

[0026] Reference Figure 1 and Figure 5 The cooling mechanism 10 includes a support frame 1001 and a motor 1002. The support frame 1001 is fixedly connected to the upper end of one side of the tail support frame 9, and the motor 1002 is fixedly connected to one end of the support frame 1001.

[0027] The rotating shaft 1003 and the cooling fan 1004 are rotatably connected to the middle of the upper part of the support frame 1001. The cooling fan 1004 is fixedly connected to one end of the rotating shaft 1003. The other end of the rotating shaft 1003 passes through the support frame 1001 and is fixedly connected to the output end of the motor 1002. The motor 1002 drives the rotating shaft 1003 to rotate, so that the cooling fan 1004 runs continuously, accelerates the air flow, and cools the inner lower mold box 6 on the tail support frame 9 where the workpiece is mounted, preventing the entire mold from being cooled, which would result in a longer demolding time.

[0028] The working principle of this utility model is as follows: During use, the inner lower mold box 6 to be used is placed on the pre-placement frame 8. When demolding is required, the cylinder 204 drives the side support 202 to move, thereby separating the upper mold cover 201 from the mold base 1. During this process, the compressed return spring 4 simultaneously releases its elastic potential energy. As the elasticity recovers, the spring-loaded plate 5 slides upward along the inner side of the mold base 1 under the action of the return spring 4, pushing the inner lower mold box 6 on its top upward until the inner lower mold box 6 is completely lifted, making it level with the pre-placement frame 8 and the tail support frame 9. At this point, the inner lower mold box 6 to be used can be pushed towards the mold base 1 until it contacts the inner lower mold box 6 with the workpiece on top of the mold base 1, forcing it to move horizontally onto the tail support frame 9. At this point, the inner lower mold box 6 to be used is located on top of the spring-loaded plate 5. Then, the cylinder 204 drives the side support 202 to move the upper mold cover 201 downward. The upper mold cover 201 is moved until it fits tightly against the mold base 1. During this process, the inner lower mold box 6 enters the interior of the mold base 1 under the pressure of the upper mold cover 201, and the compression return spring 4 returns to its initial position inside the mold base 1 under pressure, thus completing one demolding operation and preparing for the next injection molding. This method can achieve the purpose of automatic demolding without the need for manual demolding with additional tools, which greatly saves demolding time and increases the output of products per unit time. By replacing the inner lower mold box 6 to be used in conjunction with demolding, a closed-loop process of "demolding-replacement-injection molding" can be formed, which significantly shortens the single production cycle. The inner lower mold box 6 with the workpiece is mounted on the tail support frame 9. The rotating shaft 1003 is driven by the motor 1002 to rotate, so that the cooling fan 1004 runs continuously to accelerate airflow and cool the workpiece, preventing the entire mold from being cooled, which would cause the demolding time to increase.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
