Abstract
Description
Technical Field
[0001] The present application relates to the technical field of injection molds, and in particular to a molding mold. Background Art
[0002] At present, when using injection molds to mold products with complex structures such as earphone shells, two sets of oblique drawer components are usually used to cooperate with the mold core to form the structural features of the product. However, when using two sets of oblique drawer components, due to the internal space limitations of the mold, one set of oblique drawer components must be designed with a small inclination angle and the other set of oblique drawer components with a large inclination angle. In order to allow the two sets of oblique drawer components to exit the mold core at the same time, the oblique drawer component with a large inclination angle needs to be locked on the fixed mold, resulting in the need to completely disassemble the fixed mold when disassembling and maintaining the two sets of oblique drawer components, which in turn affects the efficiency of disassembling and maintaining the oblique drawer components.

Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0077] See also Figure 1 The embodiment of the present application provides a molding die 100, and the molding die 100 is used for injection molding products. The product may be an earphone shell, a mobile phone charger shell, etc. For ease of description and understanding, the embodiment of the present application takes the earphone shell as an example for description, and defines the first direction as Figure 1 , Figure 4 and Figure 5 The Z-axis direction is shown, and the second direction is Figure 1 , Figure 4 and Figure 5 In the X-axis direction shown, the first direction and the second direction are perpendicular to each other. Obviously, this is not a limitation of the embodiment of the present application.
[0078] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The molding die 100 of the embodiment of the present application includes a fixed die 10, a movable die 20, an extrusion elastic component 30, a first oblique drawer component 40, a second oblique drawer component 50 and a limiter 60.
[0079] The fixed mold 10 has a mold core 14, a guide channel 15 extending to the mold core along a first direction, and a sliding channel 114 extending along a second direction and connected to the guide channel 15. The movable mold 20 is adapted to be molded with the fixed mold 10 along the first direction, and the extrusion elastic component 30 is arranged at one end of the guide channel 15 away from the mold core 14.
[0080] The first oblique drawer assembly 40 is slidably disposed in the guide channel 15 and abuts against the extrusion elastic assembly 30. The first oblique drawer assembly 40 is provided with a limiting hole 411 communicating with the sliding channel 114, and the limiting hole 411 is extended along the first direction. The second oblique drawer assembly 50 is disposed in the fixed mold 10 and is spaced apart from the first oblique drawer assembly 40. The first oblique drawer assembly 40 and the second oblique drawer assembly 50 both correspond to the mold core 14. When the movable mold 20 and the fixed mold 10 are closed, the first oblique drawer assembly 40 and the second oblique drawer assembly 50 are inserted into the mold core 14 and cooperate with the mold core 14 to form a product.
[0081] The limit member 60 is arranged in the sliding channel 114 and is plug-in connected to the fixed mold 10. The limit member 60 is inserted into the limit hole 411. The limit member 60 is used to limit the first oblique pull-out component 40 from being disengaged from the fixed mold 10. The limit member 60 is also used to cooperate with the limit hole 411 to limit the stroke of the first oblique pull-out component 40 when the movable mold 20 and the fixed mold 10 are opened, so that the first oblique pull-out component 40 and the second oblique pull-out component 50 can exit the mold core 14 at the same time.
[0082] Specifically, the first oblique pull-out component 40 has a large inclination angle and a small stroke when the mold is opened, and the second oblique pull-out component 50 has a small inclination angle but a large stroke when the mold is opened. When the movable mold 20 and the fixed mold 10 are opened, the second oblique pull-out component 50 is first pulled out of the mold core 14 for a distance. At this time, the extrusion elastic component 30 squeezes the first oblique pull-out component 40 and limits the movement of the first oblique pull-out component 40. The limit member 60 slides in the limit hole 411 along the first direction. When the second oblique pull-out component 50 is pulled out of the mold core 14 for a certain distance, the limit member 60 abuts against the side of the limit hole 411 close to the extrusion elastic component 30, and drives the first oblique pull-out component 40 to start being pulled out of the mold core 14, so that the first oblique pull-out component 40 and the second oblique pull-out component 50 exit the mold core 14 at the same time. When the first oblique drawer assembly 40 and the second oblique drawer assembly 50 are to be disassembled for maintenance, it is only necessary to remove the mold core 14 and then pull out the limit piece 60, so that the parts of the first oblique drawer assembly 40 and the second oblique drawer assembly 50 that need to be maintained can be moved out of the fixed mold 10 without disassembling the entire fixed mold 10, thereby improving the efficiency of disassembling and maintaining the first oblique drawer assembly 40 and the second oblique drawer assembly 50.
[0083] In this embodiment, the fixed mold 10 includes a fixed component 11, a fixed mold plate 12 and a floating elastic component 13. The fixed component 11 is arranged opposite to the movable mold 20, the sliding channel 114 is opened in the fixed component 11, the limiter 60 is arranged in the sliding channel 114, and the end of the limiter 60 away from the first oblique drawer component 40 extends out of the side wall of the fixed component 11; the fixed mold plate 12 is floatingly arranged in the fixed component 11 and is located between the fixed component 11 and the movable mold 20, the mold core 14 is embedded in the side of the fixed mold plate 12 facing the movable mold 20 and is detachably connected to the fixed mold plate 12, the guide channel 15 is opened in the fixed component 11 and the fixed mold plate 12, specifically, a part of the guide channel 15 is opened in the fixed component 11, and another part of the guide channel 15 is opened in the fixed mold plate 12; the extrusion elastic component 30 is arranged The guide channel 15 is connected to the fixed component 11, and the second oblique pull-out component 50 is connected to the fixed component 11 and is slidably inserted into the fixed mold plate 12 along the first direction. When the movable mold 20 and the fixed mold 10 are closed, the fixed mold plate 12 moves toward the fixed component 11 under the extrusion of the movable mold 20, so that the first oblique pull-out component 40 and the second oblique pull-out component 50 are inserted into the mold core 14; the two ends of the floating elastic component 13 are respectively connected to the fixed component 11 and the fixed mold plate 12, and the floating elastic component 13 is used to elastically support the fixed mold plate 12 to drive the fixed mold plate 12 away from the fixed component 11 when the movable mold 20 and the fixed mold 10 are opened, so that the first oblique pull-out component 40 and the second oblique pull-out component 50 withdraw from the mold core 14. By floating the fixed mold plate 12 on the fixed component 11 and arranging the two ends of the floating elastic component 13 to be connected to the fixed component 11 and the fixed mold plate 12 respectively, it is convenient for the floating elastic component 13 and the fixed component 11 to respectively drive the first oblique pull-out component 40 and the second oblique pull-out component 50 to insert into the mold core 14 when the movable mold 20 and the fixed mold 10 are closed, and it is convenient for the first oblique pull-out component 40 and the second oblique pull-out component 50 to withdraw from the mold core 14 when the movable mold 20 and the fixed mold 10 are opened.
[0084] In this embodiment, the length of the limiting hole 411 is equal to the difference between the stroke of the second oblique pull-out component 50 exiting the mold core 14 and the stroke of the first oblique pull-out component 40 exiting the mold core 14. Exemplarily, the stroke of the first oblique pull-out component 40 exiting the mold core 14 is 5 mm, the stroke of the second oblique pull-out component 50 exiting the mold core 14 is 30 mm, and the length of the limiting hole 411 is 25 mm. Under normal conditions, the floating elastic component 13 drives the fixed mold plate 12 away from the fixed component 11. When the movable mold 20 is molded with the fixed mold 10, the movable mold 20 squeezes the fixed mold plate 12 to move toward the fixed component 11. At this time, the first oblique pull-out component 40 and the second oblique pull-out component 50 are respectively inserted into the mold core 14 driven by the extrusion elastic component 30 and the fixed component 11, so that the first oblique pull-out component 40 and the second oblique pull-out component 50 cooperate with the mold core 14 to form a product. When the movable mold 20 and the fixed mold 10 are opened, the movable mold 20 first moves 25 mm and does not separate from the fixed mold plate 12. At this time, the floating elastic component 13 drives the fixed mold plate 12 to be 25 mm away from the fixed component 11. The fixed component 11 drives the second oblique pull-out component 50 to move 25 mm out of the mold core 14. The extrusion elastic component 30 squeezes the first oblique pull-out component 40 and limits the movement of the first oblique pull-out component 40. The limiter 60 abuts against the side of the limiter hole 411 close to the extrusion elastic component 30. When the movable mold 20 continues to move and separates from the fixed mold plate 12, the fixed component 11 drives the second oblique pull-out component 50 to continue to move 5 mm out of the mold core 14. The limiter 60 cooperates with the limiter hole 411 to drive the first oblique pull-out component 40 to move 5 mm out of the mold core 14, so that the first oblique pull-out component 40 and the second oblique pull-out component 50 exit the mold core 14 at the same time.
[0085] In this embodiment, the fixing assembly 11 includes an upper fixing plate 111 , a heat flux plate 112 and a fixed mold bearing plate 113 arranged in sequence from top to bottom. The fixed mold bearing plate 113 is located between the heat flux plate 112 and the fixed mold plate 12 and is spaced apart from the fixed mold plate 12 . A portion of the guide channel 15 located on the fixed component 11 extends from the upper fixed plate 111 to the side of the fixed mold bearing plate 113 facing the fixed mold plate 12, the extrusion elastic component 30 is arranged in the guide channel 15 and connected to the upper fixed plate 111, the first oblique withdrawal component 40 is slidably arranged in the guide channel 15 and passes through the heat flow plate 112 and the fixed mold bearing plate 113 to extend into the fixed mold plate 12, the second oblique withdrawal component 50 is connected to the fixed mold bearing plate 113 and is slidably inserted into the fixed mold plate 12 along the first direction, the sliding channel 114 is opened in the fixed mold bearing plate 113, and the two ends of the sliding channel 114 are respectively connected to the outer side wall of the fixed mold bearing plate 113 and the guide channel 15, the limit member 60 is slidably arranged in the sliding channel 114, and the end of the limit member 60 away from the first oblique withdrawal component 40 extends out of the outer side wall of the fixed mold bearing plate 113, one end of the floating elastic component 13 is connected to the fixed mold plate 12, and the other end of the floating elastic component 13 passes through the fixed mold bearing plate 113 and extends into the heat flow plate 112. By designing the specific structure of the fixing component 11 , it is convenient to produce and process the fixed mold 10 , and it is convenient to assemble the extrusion elastic component 30 , the first oblique draw component 40 , the second oblique draw component 50 and the limiter 60 .
[0086] In this embodiment, the floating elastic component 13 includes a guide rod 131 and a floating elastic member 132. One end of the guide rod 131 is connected to the fixed mold plate 12, and the other end of the guide rod 131 passes through the fixed mold bearing plate 113 and is connected to the heat flow plate 112.

When the movable mold 20 and the fixed mold 10 are closed, the extrusion member 32 drives the first oblique pull-out component 40 to be inserted into the mold core 14 under the drive of the extrusion elastic member 31, thereby avoiding the rigid contact between the first oblique pull-out component 40 and the mold core 14 and effectively reducing the probability of damage to the first oblique pull-out component 40; when the movable mold 20 and the fixed mold 10 are opened, the extrusion member 32 continues to extrude the first oblique pull-out component 40 under the drive of the extrusion elastic member 31 to delay the time for the first oblique pull-out component 40 to exit the mold core 14, thereby facilitating the first oblique pull-out component 40 and the second oblique pull-out component 50 to exit the mold core 14 at the same time.
