[0021] When the injection mold for the transfer insulating core of the present invention is closed, the front mold core 10 and the rear mold core 20 cooperate, and the protrusion 201 of the rear mold core 20 is inserted into the groove 101 of the front mold core 10. The first slider assembly 3 and the second slider assembly 4 both cooperate with the mold cavity to facilitate the injection molding of the colloid into the mold cavity, thereby obtaining the transfer insulating core. The arrangement of the protrusion 201 and the groove 101 facilitates the accurate alignment of the front and rear mold cores. At the same time, the inclined arrangement of the side walls of the two facilitates the separation of the front mold core 10 from the rear mold core 20 during demolding, avoiding the phenomenon of the two being stuck when inserted vertically, thereby ensuring the normal opening and closing of the mold.

[0022] The first slider assembly 3 includes a first oblique guide rod 31, a first slider 32, a first moving block 33 and a first guide block 34. One end of the first slider 32 extends into the mold cavity, and the other end is connected to the first moving block 33. The first moving block 33 is arranged on the rear template 7. One end of the first oblique guide rod 31 is fixed on the front template 6, and the other end can pass through the first moving block 33. The first oblique guide rod 31 is arranged at an angle, and the first guide block 34 is fixed below the front template 6. A first inclined surface is provided on the inner side of the first guide block 34, and a second inclined surface is provided on the outer side of the first moving block 33. The first inclined surface can be fitted with the second inclined surface.

[0023] When closing the mold, the front template 6 drives the first inclined guide rod 31 to move downward, and under the guidance of the first inclined guide rod 31, drives the first moving block 33 to move toward the side close to the cavity, thereby driving one end of the first slider 32 to extend into the cavity; at the same time, when the front template 6 moves toward the side of the rear template 7, it drives the first guide block 34 to move downward together, so that the first inclined surface acts on the second inclined surface, and jointly pushes the first moving block 33 to move toward the side of the cavity to achieve mold closing.

[0024] When the mold is opened, the front template 6 moves upward in the opposite direction, thereby driving the first inclined guide rod 31 to move upward. Under the action of the first inclined guide rod 31, the first moving block 33 is pushed outward, so that the first moving block 33 and the first slider 32 move outward, so that the first slider 32 is demolded and separated from the product formed in the mold cavity; at the same time, the first guide block 34 is pulled upward together by the front template. Due to the setting of the first inclined surface, sufficient space is provided for the first moving block 33 to move outward.

[0025] The second slider assembly 4 comprises a second inclined guide rod 41, a second slider 42, a second moving block 43 and a second guide block 44, one end of the second slider 42 extends into a cavity, the other end is connected with the second moving block 43, the second moving block 43 is arranged on the rear mold plate 7, one end of the second inclined guide rod 41 is fixed on the front mold plate 6, the other end can penetrate through the second moving block 43, the second inclined guide rod 41 is arranged obliquely, the second guide block 44 is fixed below the front mold plate 6, the inner side of the second guide block 44 is provided with a third inclined surface, and the outer side of the second moving block 43 is provided with a fourth inclined surface, and the third inclined surface can be matched with the fourth inclined surface.

[0026] The second slider assembly 4 moves in the same way as the first slider assembly 3 when the mold is opened and closed, and the second slider 42 moves to one side of the cavity by moving the front mold plate 6 downward, and is matched with the cavity; the second slider 42 is separated from the cavity by moving the front mold plate 6 upward, and the second slider is demolded.

[0027] The rear mold core 20 is provided with a through hole, a sleeve 50 is arranged in the through hole, and the rear mold insert 40 is matched with the sleeve 50. The sleeve 50 is sleeved and fixed in the through hole, which is convenient for molding the corresponding shape of the product, without the need to process the through hole of the rear mold core 20 which is relatively large in volume, and is beneficial to simplify the processing of the mold.

[0028] The adapter insulating inner core injection mold also comprises a reset spring 60 and a mounting rod 70, one end of the mounting rod 70 is fixed on the ejector pin plate 1, the other end can penetrate through the rear mold plate 7, the reset spring 60 is sleeved on the mounting rod 70, one end of the reset spring 60 abuts against the ejector pin plate 1, and the other end abuts against the rear mold plate 7.

[0029] The adapter insulating inner core injection mold also comprises a guide column 80, one end of the guide column 80 is fixed on the rear mold plate 7, the other end can penetrate through the rear mold plate 7 and extend into the front mold plate 6. Therefore, when the mold is opened and closed, the front mold plate 6 can realize accurate mold closing with the rear mold plate 7 under the guidance of the guide column 80, which is beneficial to ensure the injection molding precision of the product.

[0030] The opening and closing process of the adapter insulating inner core injection mold is as follows:

[0031] When the mold is closed, the front mold plate 6 moves to one side of the rear mold plate 7, so that the front mold core 10 is matched with the rear mold core 20; when the front mold plate 6 moves to one side of the rear mold plate 7, the first slider 32 and the second slider 42 are correspondingly driven to move to one side of the cavity and are matched with the cavity, and the mold closing is completed. After the mold closing is completed, glue is injected into the cavity, the injection molding is completed, and the adapter insulating inner core (as shown in the drawing) is obtained. Figure 8

[0032] ​After the injection molding is completed, the mold is demolded. During demolding, an external force opens the front template 6. When the front template 6 moves away from the rear template 7, the front mold core 10 and the front mold insert on the front mold core gradually separate from the product in the cavity. When the front template 6 moves, it drives the first slider 32 and the second slider 42 to move outward, separating from the product molded in the cavity, thereby achieving demolding of each slider. After each slider is demolded and separated from the product, the ejector plate 1 moves upward, driving the ejector 2 to move upward. The ejector 2 ejects the product in the cavity, thereby achieving demolding of the product. When the ejector plate 1 moves upward, the reset spring 60 is compressed. After the product is ejected and demolded, the rebound force of the reset spring 60 drives the ejector plate 1 downward, thereby driving the ejector 2 downward to reset, which is convenient for the next injection molding.

[0033] The above are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
