Detailed Implementation
[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0026] like Figures 1 to 7 As shown, a multi-cavity oblique hole injection mold includes a device body, characterized in that the device body includes a first injection structure located on the front and rear sides, a second injection structure located on the left and right sides, a third injection structure located on the upper and lower sides, and two fourth injection structures 5 disposed directly above the second injection structure 3.
[0027] The first injection molding structure 2 includes a first insert block 21, a first slider structure 22, and a first injection rod 23. The first slider structure 22 has a first insertion hole. The first insert block 21 is inserted downward into the first insertion hole of the first slider structure 22 to drive the first slider structure 22 to move towards the injection molded part. The first injection rod 23 is fixed on the first slider structure 22 and is set towards the front or rear side of the injection molded part. When the first insert block 21 is inserted downward into the first slider structure 22, the first slider structure 22 has a first inclined part 221 and the first insert block 21 also has a second inclined part 211. This causes the first insert block 21 to push the first injection rod 23 on the first slider structure 22 towards the injection molded part when it is inserted downward into the first slider structure 22, thereby inserting the first injection rod 23 set on the front and rear sides into the injection molded part, which is beneficial for automatically injecting the front and rear sides of the injection molded part.
[0028] The second injection molding structure 3 includes a second insert block 31, a second slider structure 32, and a second injection rod 33. The second slider structure 32 has two insertion holes 34. The second insert block 31 is inserted downward into the second insertion hole of the second slider structure 32 to drive the second slider structure 32 to move towards the injection molded part. The second injection rod 33 is fixed on the second slider structure 32 and is set towards the left or right side of the injection. Through the action of the film-closing force, the second slider structure 32 has a third inclined part 321, and the second insert block 31 also has a fourth inclined part 311. This causes the second insert block 31 to push the second injection rod 33 on the second slider structure 32 towards the injection molded part when it is inserted downward into the second slider structure 32, thereby inserting the second injection rod 33 set on the left and right sides into the injection molded part, which is beneficial for automatically injecting the left and right sides of the injection molded part.
[0029] The third injection molding structure 4 includes a telescopic rod 41 and a third injection rod 42 located at the bottom of the injection molded part. The third injection rod 42 is installed on the telescopic rod 41 and extends upward and through the injection molded part. Through the stretching action of the telescopic rod 41, the third injection rod 42 on the telescopic rod 41 is driven to move upward and insert into the injection molded part for automatic injection molding.
[0030] The fourth injection molding structure 5 includes a second inclined injection rod 51, a third insert block 52, a third slider structure 53, and a third inclined injection rod 54. The second slider structure 32 is also equipped with an inclined second injection rod 51, with the rod head of the second inclined injection rod 51 facing the injection molded part. The third slider structure 53 has a third insert hole 55, and the third insert block 52 is inserted into the third insert hole 55 for moving towards the injection molded part. The second slider structure 32 is fixed with a third inclined injection rod 54, which faces the injection molded part. The third insert 52 is inserted downward into the third slider structure 53. Due to the action of the film-closing force, the third slider structure 53 has a fifth inclined portion 531, and the third insert 52 also has a sixth inclined portion 521. When the third insert 52 is inserted downward into the third slider structure 53, it can push the third injection rod 42 on the third slider structure 53 to move towards the injection part, thereby inserting the third injection rod 42 set on the front and rear sides into the injection part. This is beneficial for automatically injecting the upper hemisphere position of the injection part at an angle. The second slider structure 32 also has a seventh inclined portion 81, and the second insert 31 also has an eighth inclined portion 82. A travel gap is provided between the seventh inclined portion 81 and the eighth inclined portion. When the third inclined injection rod 54 set on the eighth inclined portion 82 is subjected to the force of the second insert 31 towards the second slider structure 32, it can drive the third inclined injection rod 54 to automatically inject the lower hemisphere position of the injection part at an angle while the second injection rod 33 is inserted into the injection part.
[0031] The second injection molding structure 3 also includes two first oblique injection molding rods 6 symmetrically arranged on both sides of the second injection molding rod 33. The second slider structure 32 is also symmetrically equipped with a push assembly, each of which is provided with a first oblique injection molding rod 6 for obliquely inserting the injection molded part in the horizontal direction.
[0032] By advancing the two first oblique injection rods 6 through the propulsion assembly, it is beneficial to automatically insert the injection molded part obliquely in the horizontal direction.
[0033] By adopting the above structure, the first injection molding structure 2, the second injection molding structure 3, the third injection molding structure 4, and the fourth injection molding structure 5 work together to exert the film-forming force. The first injection molding rod 23, the second injection molding rod 33, the third injection molding rod 42, the first inclined injection molding rod 6, the second inclined injection molding rod 51, and the third inclined injection molding rod 54 work together to automatically inject the molded parts. This greatly improves the injection molding processing efficiency, while reducing the use of oil pumps and cylinders, and significantly reducing the weight of the device and processing costs.
[0034] like Figures 1 to 7As shown, the second slider structure 32 has a propulsion cavity 71. The propulsion assembly is a propulsion block 73 that can push the first inclined injection rod 6. The propulsion block 73 is installed in the propulsion cavity 71 with a propulsion gap 72. The first inclined injection rod 6 for oblique insertion of the injection molded part is installed on the propulsion block 73. By setting the propulsion block 73, the propulsion block 73 pushes two first inclined injection rods 6 forward, which is beneficial for automatic oblique insertion of the injection molded part in the horizontal direction without the need for additional slider structures, thus reducing the processing cost of the device.
[0035] like Figures 1 to 7 As shown, the first injection rod 23 is aligned with the front and rear of the injection molded part. This structure facilitates automatic and precise injection molding of the front and rear of the injection molded part, resulting in higher injection quality.
[0036] like Figures 1 to 7 As shown, the second injection molded part is aligned with the left and right sides of the injection molded part. This structure facilitates automatic and precise injection molding of the left and right sides of the injection molded part, resulting in higher injection quality.
[0037] like Figures 1 to 7 As shown, the third injection rod 42 is aligned directly below the injection molded part. This structure facilitates automatic and precise injection molding from both directly below and above the injection molded part, resulting in higher injection quality.
[0038] like Figures 1 to 7 As shown, the first angled injection rod 6, the second angled injection rod 51, and the third angled injection rod 54 are all aligned with the injection molded part. This structure facilitates automatic and precise injection molding in the angled direction of the injection molded part, resulting in higher injection quality.
