[0019] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.
[0020] like Figures 1 to 4 As shown, it is a schematic diagram of the structure of the global camera housing cover molding die provided by the present invention. The global camera housing cover molding die includes an upper mold base assembly 10, an upper mold assembly 20 arranged on the upper mold base assembly 10, a lower mold base assembly 30 matched with the upper mold base assembly 10, a lower mold assembly 40 arranged on the lower mold base assembly 30, an exhaust assembly 50 arranged on the lower mold assembly 40, a pouring assembly 60 arranged on the lower mold assembly 40, and a side die drawing assembly 70 arranged on the lower mold base assembly 30. It can be imagined that the global camera housing cover molding die also includes some other functional modules, such as assembly components, installation components, temperature control components, and ejector components, etc., which are well known to those skilled in the art and will not be repeated here.
[0021] First of all, it should be noted that the global camera housing cover forming mold is used to cast the material into a die casting 100. A through hole 110 is provided on one side of the die casting 100. It can be imagined that the die casting 100 itself should be a prior art and will not be described in detail here.
[0022] The upper die base assembly 10 includes an upper die base 11 , four guide posts 12 disposed at four corners of the upper die base 11 , and a pouring hole 13 disposed on the upper die base 11 .
[0023] The upper die seat 11 is connected to an external moving device, and the upper die seat assembly 10 is driven to reciprocate along its axial direction by the external moving device to realize the opening or closing of the upper die assembly 20 and the lower die assembly 40. An upper die mounting groove is provided on an end surface of the upper die seat 11 facing the lower die assembly 40. The upper die mounting groove is used to set the upper die assembly 20. The guide column 12 is used to cooperate with the lower die seat assembly 30 and guide, so as to ensure the accuracy when closing the mold. The pouring hole 13 is used to set the pouring assembly 60.
[0024] The upper mold assembly 20 includes an upper mold body 21 disposed on the upper mold base 11 , a molding groove 22 disposed on the upper mold body 21 , a flow channel 23 disposed on the upper mold body 21 , and an opening 24 disposed on one side of the upper mold body 21 .
[0025] The upper mold body 21 moves with the upper mold base 11 and is used to set the above-mentioned functional components. The molding groove 22 is set on an end surface of the upper mold body 21 facing the lower mold assembly 40. After the upper mold assembly 20 and the lower mold assembly 40 are molded together, the molding groove 22 is spaced apart from the molding protrusion 42 described below, so that a molding cavity is formed between the molding groove 22 and the molding protrusion 42 described below. The molding cavity is used to contain the die-casting solution to mold the die-casting part 100.
[0026] The flow channel 23 includes two main flow channels 231 arranged on the upper mold body 21, a plurality of branch flow channels 232 arranged on the upper mold body 21, and two slag holes 243 arranged on the upper mold body 21 and respectively connected to the two main flow channels 231. One end of the main flow channel 231 is connected to the casting assembly 60, and the other end is connected to the slag hole 243, and the angle between the flow directions of the two main flow channels 231 is an obtuse angle. One end of the branch flow channel 232 is connected to the main flow channel 231, and the other end is connected to the molding cavity and its opening size gradually increases. The opening of the branch flow channel 232 gradually increases from the main flow channel 231 toward the molding cavity, so as to gradually reduce the speed while ensuring the pressure, so as to achieve the purpose of filling the molding cavity. The main channel 231 and the branch channel 232 are located on one side of the molding cavity. When the material to be poured flows from the pouring assembly 60 into the main channel 231, it is diverted by the branch channel 232 and then flows into the molding cavity from one side to fill it. Each adjacent branch channel 232 is arranged at intervals, so that the pressure of the material flowing in can be reduced and made uniform, avoiding product deformation or uneven filling. Two slag holes 243 are located at the end of the main channel 231, and are used to collect the cold material generated between two pourings and the air in the flow channel, so as to prevent the main channel 231 or the branch channel 232 from being blocked, and to speed up the flow rate of the injection, but it is a prior art itself and will not be described here.
[0027] The opening 24 is used to avoid the side mold extraction assembly 70 so that the side mold extraction assembly 70 can extend into the upper mold body 21. Therefore, the structure and size of the opening 24 should be adapted to the structure and size of the side mold extraction assembly 70.
[0028] The lower die base assembly 30 includes a lower die base 31 located directly below the upper die base 11, and four guide sleeves 32 arranged at the four corners of the lower die base 31. The lower die base 31 is provided with a lower die mounting groove on one end surface facing the lower die assembly 40. The lower die mounting groove is used to set the lower die assembly 40. The lower die base 31 is used to set the lower die assembly 40, the exhaust assembly 50, the pouring assembly 60, and the side die drawing assembly 70. Therefore, the lower die base 31 is provided with a variety of functional structures, such as a plurality of mounting grooves of different sizes, etc., to complete the installation and assembly of the above functional modules, which can be set according to actual needs, and will not be described in detail one by one here. The guide sleeve 32 arranged at each corner coincides with the central axis of the guide column 12 at each corner, so when the guide column 12 is inserted in the guide sleeve 32, the accuracy of the upper die base assembly 10 and the lower die base assembly 30 when the mold is closed is guaranteed. The guide column 12 and the guide sleeve 32 themselves should be prior art for those skilled in the art and will not be described in detail here.
[0029] The lower die assembly 40 includes a lower die body 41 disposed in the lower die seat 31, and a molding protrusion 42 disposed on the lower die body 41. The lower die body 41 is fixedly disposed in the lower die groove for arranging the molding protrusion 42. The molding protrusion 42 fits with the molding groove 22 and is used to form the molding cavity after the molding is closed with the molding groove 22.
[0030] The exhaust assembly 50 includes a plurality of exhaust grooves 51 disposed on the lower mold body 41 , at least two lower exhaust blocks 52 disposed on the lower mold body 41 , and at least two upper exhaust blocks 53 disposed on the upper mold body 21 .
[0031] The exhaust groove 51 and the main flow channel 231 and the branch flow channel 232 are respectively arranged on the opposite sides of the molding cavity and are centrally arranged, and the exhaust groove 51 is located on one side of the molding cavity. One end of the exhaust groove 51 is connected to the molding cavity, and the other end is connected to the upper and lower exhaust blocks 53, 52, so as to discharge excess material and air to the upper and lower exhaust blocks 53, 52. The flow channel 23 and the exhaust groove 51 are respectively located on both sides of the molding cavity, so that when the material flows into the molding cavity from one side, the air in the molding cavity can be discharged from the other side of the molding cavity, which is more conducive to the discharge of air, makes the filling faster, and makes the air discharged in a centralized manner, so as to avoid air remaining in the molding cavity, so as to prevent the product from being deformed or bubbles appearing. One end face of the lower exhaust block 52 is flush with the top surface of the lower mold body 41. One end face of the upper exhaust block 53 is flush with the bottom face of the upper mold body 21, so that when the upper mold body 21 and the lower mold body 41 are molded together, the lower exhaust block 52 and the upper exhaust block 53 are closed to each other, thereby forming an exhaust airway. In order to improve the exhaust effect, the lower exhaust block 52 is provided with a plurality of array-arranged protrusions 521, and the upper exhaust block 53 is concavely provided with a plurality of grooves 531. After the mold is closed, the protrusions 521 are inserted into the grooves 531, and there is a gap between the protrusions 521 and the grooves 531, so that air can be discharged from the gap to improve the exhaust effect. At the same time, it can also effectively resist the material solution and prevent the material solution from rushing out of the upper and lower exhaust blocks 53 and 52, causing the phenomenon of flying materials, so as to ensure the safety of molding.
[0032] The casting assembly 60 includes two first slide rails 61 arranged on the lower mold base 31, a first slider 62 slidably arranged on the first slide rails 61, a sleeve 63 arranged in the casting hole 13, a guide column 64 arranged on the first slider 62, and two first slide rods 65 obliquely arranged on the first slider 62.
[0033] The two ends of the first slider 62 are respectively slidably arranged on the two first slide rails 61, so that the first slider 62 can slide along the first slide rails 61. The first slider 62 extends into the upper mold body 21 and abuts against the side wall of the die casting 100, and fits with the upper mold body 21 when the mold is closed, thereby closing the main flow channel 231 and the branch flow channel 232 to form a channel for circulating the casting solution, and the casting solution flows on the smooth and flat surface of the first slider 62, so that the casting solution flows faster and the distance is shorter, shortening the filling stroke. The sleeve 63 is arranged in the pouring hole 13 and is used to add the casting solution. The sleeve 63 is provided with a discharge port 631 on one side of the flow channel 23, and the casting solution flows out from the discharge port 631 and then flows into the main flow channel 231. The guide column 64 is arranged on the first slider 62 and is located in the sleeve 63. The top surface of the guide column 64 is inclined. The guide column 64 is provided with a guide groove 641 on the side facing the discharge port 631. The guide groove 641 is connected to the main channel 231. The guide column 64 and the guide groove 641 are used to even out the speed of material flow and avoid excessive pressure when the material just enters the main channel 231. One end of the first slide bar 65 is fixedly arranged on the upper die seat 11, and the other end is inserted into the first slider 62. Two first slide bars 65 are located on both sides of the sleeve 63. When the mold is separated, the upper mold base assembly 10 and the lower mold base assembly 30 are separated. Since the first slide bar 65 is tilted, the first slide bar 62 slides along the direction of the central axis of the first slide bar 65 under the drive of the lower mold base assembly 30 and the guidance of the first slide bar 65 and the first slide rail 61, so that the guide column 64 and the sleeve 63 and the first slide bar 62 and the die-casting 100 are separated from each other, thereby facilitating the demoulding of the die-casting 100 and cleaning the waste in the sleeve 63 and the molding cavity.
[0034] The side die drawing assembly 70 includes two second slide rails 71 arranged on the lower die base 31, a second slider 72 slidably arranged on the second slide rails 71, a drawing block 73 arranged on the second slider 72, and a second slide rod 74 obliquely arranged on the upper die base 11.
[0035] The two ends of the second slider 72 are respectively slidably arranged on the two second slide rails 71, so that the second slider 72 can slide on the two second slide rails 71. The draw block 73 is fixedly arranged on the second slider 72 and moves with the second slider 72. The draw block 73 passes through the opening 24 and abuts against one side of the forming protrusion 42. The draw block 73 is used to form the through hole 110. One end of the second slide rod 74 is fixedly arranged on the upper die seat 11, and the other end is inserted into the second slider 72. The sliding principle of the second slider 72 is the same as that of the first slider 62, which will not be repeated here. When the mold is separated, the draw block 73 is pulled out of the through hole 110 driven by the second slider 72, and then the die casting 100 is taken out.
[0036] Compared with the prior art, the global camera housing cover molding die provided by the present invention designs the structure and position of the flow channel 23 and the exhaust component 50. Specifically, the flow channel 23 includes a main flow channel 231, a branch flow channel 232, and a slag hole 243. The main flow channel 231 and the branch flow channel 232 are located on one side of the molding cavity, while the exhaust component 50 is located on the other side of the molding cavity, and the exhaust groove 51 of the exhaust component 50 is centrally arranged. When the material flows into the molding cavity from one side, the air in the molding cavity can be discharged from the other side of the molding cavity, so that the air is discharged in a centralized manner, which is more conducive to the discharge of air and makes the filling faster. At the same time, it is avoided that the air remains in the molding cavity to prevent the product from being deformed, and the casting solution flows on the smooth and flat surface of the first slider 62, so that the casting solution flows faster and the distance is shorter, shortening the filling stroke. In addition, when the mold is separated, the first slider 62 will slide along the direction of the central axis of the first slide rod 65 under the drive of the lower mold base assembly 30 and the guidance of the first slide rod 65 and the first slide rail 61, so that the guide column 64 and the sleeve 63 and the first slider 62 are separated from the die casting 100, thereby facilitating the demolding of the die casting 100 and cleaning of the casting assembly 60.
