Description

Technical Field

[0001] This utility model relates to the field of insert separation technology, specifically to an injection-molded insert separation device. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are typically made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Some workpieces require the use of cores during injection molding, and these cores need to be removed after the injection molding process. Currently, this process requires manually separating each product from the core, which is inefficient; the cores are exposed to high temperatures when removed from the mold, posing a risk of burns; and long-term manual operation is physically demanding.

[0003] Most existing separation processes require manual separation of products from the core one by one, which is inefficient. Long-term manual operation is physically demanding for workers, and the core is hot when it is removed from the workpiece, posing a risk of burns. Utility Model Content

A second fixing plate 3 is movably connected to the top of the slide rails 21. Slide grooves 26 are provided at both ends of the bottom of the second fixing plate 3. A cylinder 20 is fixedly connected to one side of the top of the base 1. The power output end of the cylinder 20 is fixedly connected to one side of the second fixing plate 3. A first positioning hole 27 is provided on the top of both the first fixing plate 2 and the second fixing plate 3. A positioning rod 35 is placed, and a first limiting block 36 is fixedly connected to one end of the positioning rod 35. The first limiting block 36 is located on one side of the second fixing plate 3. A core 34 is fixedly connected to one end of the positioning rod 35. An injection molded part 5 is connected to the outside of the core 34. A second limiting block 33 is fixedly connected to one end of the injection molded part 5. The second limiting block 33 is located on one side of the first fixing plate 2. A clamping assembly is provided on the top of the base 1. A feeding assembly is provided on one side of the bottom of the base 1. A cooling assembly is provided on one side of the bottom of the base 1.

[0027] The top of both the first fixing plate 2 and the second fixing plate 3 are movably connected with pins 29, and the top end of the pressure plate 4 is provided with a pin hole 32.

[0028] Specifically, multiple positioning rods 35 are placed in the first positioning holes 27 at the top of the first fixed plate 2 and the second fixed plate 3. Multiple pressure plates 4 are rotated, and the pressure plates 4 rotate along the through holes 28 until they close to the tops of the first fixed plate 2 and the second fixed plate 3 respectively. The positioning rods 35 are limited by the second positioning holes 31 and the first positioning holes 27. The pin 29 is pushed until one end is inserted into the pin hole 32, locking the pressure plate 4. The cylinder 20 is activated, pulling the second fixed plate 3 to slide along the slide rail 21. The first fixed plate 2 and the second limiting block 33 are then engaged. A unidirectional force is applied to the injection molded part 5, while the second fixing plate 3 and the first limiting block 36 cooperate to apply a reverse force to the core 34, separating the core 34 from the injection molded part 5. The separated injection molded part 5 is output through the feeding assembly. At the same time, during the separation process, the feeding assembly drives the cooling assembly to cool the core 34. This solves the problem that most existing separation processes require manual separation of products from the core one by one, which results in low work efficiency, long-term manual operation, high physical exertion for workers, and the risk of burns when the core is removed from the workpiece due to its high temperature.

[0029] Example 2

[0030] Please see Figure 1-3 The feeding assembly includes a drive motor 23. One side of the drive motor 23 is fixedly connected to one side of the bottom of the base 1.

Fan blades 18 are fixedly connected to the top of the first gear 15 and multiple second gears 16. Multiple ventilation slots 19 are provided on one side of the top of the base 1.

[0034] Specifically, the separated injection molded part 5 falls to the top of the conveyor belt 37 through the through groove 22. Under the action of the drive motor 23, the first feeding roller 24 is rotated, which conveys the injection molded part 5 to the guide plate 6 for discharge. At the same time, the first feeding roller 24 drives the second bevel gear 8 to rotate. Through the cooperation of the second bevel gear 8 and the first bevel gear 19, the first pulley 11 is rotated. Under the action of the transmission belt 14, the first gear 15 is rotated. Under the action of the toothed belt 17, multiple second gears 16 are rotated, which causes multiple fan blades 18 to generate upward airflow. During the pulling process of the second fixed plate 3, the airflow cools the core 34 through the ventilation groove 19 to prevent burns when the core 34 is removed for further separation.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
