[0020] Referring to Figures 1-7 The socket shell injection mold comprises a ejector rod plate 1, an ejector rod 2, a slider assembly 3, a front mold insert 4, a rear mold insert 5, a front mold insert pin 6, a rear mold insert pin 7, and a face plate 8, an upper mold plate 9, a lower mold plate 10, a square iron 20 and a bottom plate 30 arranged in sequence from top to bottom, a front mold core 40 is arranged below the upper mold plate 9, a rear mold core 50 is arranged above the lower mold plate 10, the front mold core 40 and the rear mold core 50 are arranged correspondingly and form a cavity, the slider assembly 3 is arranged correspondingly with the cavity, the front mold insert 4 is a plurality of and is fixed on the front mold core 40, the ejector rod plate 1 is arranged on the inner side of the square iron 20, one end of the ejector rod 2 is fixed on the ejector rod plate 1, the other end can penetrate the lower mold plate 10 and extend into the cavity, the rear mold insert 5 is a plurality of and is fixed on the rear mold core 50, the front mold insert pin 6 is fixed in one of the front mold inserts 4, the rear mold insert pin 7 is fixed in one of the rear mold inserts 5, the bottom end of the front mold insert pin 6 is provided with a groove 61, the top end of the rear mold insert pin 7 is provided with a protrusion 71, the protrusion 71 is matched with the groove 61, the outer periphery of the front mold insert pin 6 is provided with a first ventilation groove 62 and a second ventilation groove 63, the first ventilation groove 62 is horizontally arranged, the second ventilation groove 63 is vertically arranged and penetrates the top end of the front mold insert pin 6, the first ventilation groove 62 is communicated with the second ventilation groove 63, and the second ventilation groove 63 is located above the cavity.
[0021] The cavity in the socket shell injection mold is two, which facilitates the injection molding of two socket shells (as shown in the figure) at one time and improves the production efficiency of the mold. Figure 8
[0022] When the socket shell injection mold is closed, the protrusion 71 on the back mold pin 7 is inserted into the groove 61 of the front mold pin 6, so that they can be tightly fitted; at the same time, the side wall of the protrusion 71 is inclinedly arranged, and the inner wall of the groove 61 is correspondingly inclinedly arranged, so that the mold can be better separated from the back mold pin 7 and the front mold pin 6 when demolding.
[0023] When the mold is closed for injection, the cavity is injected, and the air in the cavity can enter the first ventilation groove 62 through the gap between the front mold pin 6 and the front mold insert 4, and then enter the second ventilation groove 63 through the first ventilation groove 62, so that the air can be easily discharged through the second ventilation groove 63, avoiding the accumulation of air in the cavity, thereby avoiding the formation of air holes on the product, and effectively avoiding the formation of air holes on the product. Ensure the quality of the injection molding product. In actual injection, the gap between the front mold pin 6 and the front mold insert 4 allows air to pass through, but the gel during injection cannot pass through.
[0024] The slider assembly 3 includes a slider 31, a moving block 32, an inclined guide rod 33, and a side pin 34. The slider 31 is located on the side of the cavity, the moving block 32 is located on the lower mold plate 10, one end of the inclined guide rod 33 is fixed on the upper mold plate 9, the other end can be inserted into the moving block 32, the slider 31 is fixed with the moving block 32, and the side pin 34 is fixed on one end of the slider 31, and the other end can extend into the cavity.
[0025] The slider assembly 3 further includes a spring 35, one end of the spring 35 is fixed in the moving block 32, and the other end abuts against the side wall of the back mold core 50. When the slider 31 moves to the side of the cavity, the moving block 32 is tightly attached to the back mold core 50, and at this time, the spring 35 is in a compressed state. When the mold needs to be opened, the inclined guide rod 33 pulls the moving block 32 with an outward pulling force, the spring 35 rebounds, so that the side surface of the slider 31 is separated from the corresponding side surface of the product injected in the cavity, facilitating the demolding separation of the slider 31 and the product.
[0026] The slider assembly 3 further includes a guide block 36, the guide block 36 is fixed below the upper mold plate 9, the inner side wall of the guide block 36 is inclinedly arranged, and the outer side wall of the moving block 32 is inclinedly arranged. The inner side wall of the guide block 36 can abut against the inner side wall of the moving block 32.
[0027] Specifically, when the mold needs to be closed, the upper mold plate 9 moves downward and approaches the lower mold plate 10. When the upper mold plate 9 moves downward, the guide block 36 and the inclined guide rod 33 are driven to move downward, so that the inclined guide rod 33 is inserted into the moving block 32, and the moving block 32 is driven to move to one side of the cavity under the action of the inclined guide rod 33. When the upper mold plate 9 moves downward to the position, the sliding block 31 is driven to move to one side of the cavity.
[0028] When the product in the cavity is injected, the upper mold plate 9 moves upward and drives the inclined guide rod 33 to move upward. Under the action of the inclined guide rod 33, the moving block 32 is driven to move away from the cavity, thereby driving the sliding block 31 to move away from the cavity, so that the sliding block 31 and the product are separated, and the product is demolded.
[0029] The rear mold insert 5 matched with the rear mold pin 7 is provided with a through hole 51, and the through hole 51 is horizontally arranged. The rear mold pin 7 penetrates the through hole 51 from top to bottom, and the other end of the side pin 34 can extend into the through hole 51. The through hole 51 is located below the cavity. When the product in the cavity is injected, the air in the cavity can also enter the through hole 51 through the gap between the rear mold pin 7 and the rear mold insert 5, so that the air in the cavity is prevented from accumulating and the product is prevented from forming pores.
[0030] The socket shell injection mold further comprises a reset spring 60 and a mounting rod 70. One end of the mounting rod 70 is fixed on the ejector plate 1, and the other end can penetrate the lower mold plate 10. The reset spring 60 is sleeved on the mounting rod 70, one end of the reset spring 60 abuts against the ejector plate 1, and the other end abuts against the lower mold plate 10. When the ejector plate 1 moves upward, the reset spring 60 is compressed. When the ejection of the top pin 2 is completed, the rebound force of the reset spring 60 drives the ejector plate 1 to move downward and reset, so that the mold closing and opening of the next time are facilitated.
[0031] The opening and closing process of the socket shell injection mold is as follows:
[0032] When the mold is closed, the upper mold plate 9 and the lower mold plate 10 are pressed tightly, the front mold core 40 is matched with the rear mold core 50, and the sliding block 31 moves to one side of the cavity and is matched with the cavity, so that the mold is closed. When the mold is closed, the product in the cavity is injected, and the corresponding socket shell is obtained.
[0033] After the product is injection molded, the mold is opened, the panel 8 and the upper mold plate 9 move upward, the upper mold plate 9 drives the sliding block 31 to move away from the cavity, so that the sliding block 31 is separated from the product. With the gradual upward movement of the upper mold plate 9, the upper mold plate 9 drives the inclined guide rod 3 to move upward together, under the guidance of the inclined guide rod 3, the sliding block 4 is pushed to move outward as a whole, so that the second moving block 42 is completely separated from the product. When the upper mold plate 9 moves upward to the position, the front mold core 40 is separated from the product, the ejector plate 1 moves upward, the ejector plate 1 drives the ejector pin 2 to move upward, the ejector pin 2 upwardly ejects the product from the cavity, and the demolding of the product is realized.
[0034] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the inventive concept of the present application, can make a number of deformation and improvement, these all belong to the protection scope of the present application.
