Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to an eagle beak forming mechanism and a mold for producing an air guide plate having the eagle beak forming mechanism. Background Art

[0002] The existing air guide plate production molds produce air guide plates that are easy to break during use, resulting in poor quality of finished air conditioners, customer complaints, and a huge waste of human and financial resources, affecting the company's image. Therefore, it is urgent to improve the current production situation.

[0003] The applicant has conducted a comprehensive analysis of the cavity, molding cycle, and cooling effect of the beak molding part of the existing air deflector production mold, and found that the existing air deflector production mold has at least the following defects:

[0004] (1) The cooling water circuit of the mold is mainly used to cool the plane of the air guide plate, but the beak 1 located at both ends of the air guide plate is far away from the cooling water circuit. The existing cooling water circuit has no cooling effect on the beak 1. Since the beak 1 is not cooled in time after the high-temperature molding of the plastic, the beak 1 of the product shrinks and the molding strength is insufficient. (2) Figure 1 As shown, the movable mold insert 2 of the mold only contains a part of the beak wall. Specifically, the beak 1 has a wall thickness of 1.5958mm and is not covered by the passive mold insert 2. A parting line 3 is generated between the side covered by the passive mold insert 2 and the side not covered by the passive mold insert 2 on the outer surface of the beak 1. Since the slider insert and the movable mold insert 2 of the mold frequently collide and move, and the beak 1 of the air guide plate product is between the slider insert and the movable mold insert 2, the beak 1 of the product has quality risks such as part assembly step difference and parting line burr. Specifically, the slider insert and the movable mold insert 2 respectively contain a part of the beak 1. Each time the slider insert and the movable mold insert 2 are formed, they will be closed once. Long-term production will cause wear of the two parts. The wall thickness of the assembled parts is different. The clamping line of the product beak is prone to gaps during molding. The clamping line is located at the glue surface of the slider insert and the movable mold insert 2, which produces a height difference. Therefore, the parting surface of the product beak 1 will produce step difference and burr quality problems.

[0005] The above defects of the air deflector production mold lead to the failure of the air deflector beak structure with a strength greater than 400N and no burrs and other quality problems to be stably produced, resulting in poor quality of finished products and customer complaints. Therefore, it is urgent to improve the beak forming mechanism of the existing air deflector production mold. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] Below is combined with Examples 1 and 2 and the appendix of the specification Figures 2 to 4 The hawk beak forming mechanism and the mold for producing the air guide plate of the present invention are described in detail.

[0032] Example 1

[0033] This embodiment is combined with the specification Figures 2 to 4 The eagle beak forming mechanism is described in detail.

[0034] The beak forming mechanism of this embodiment includes a beak cooling assembly, which is located below the beak accommodating portion and cools the beak 1 contained in the beak accommodating portion by a coolant flowing through the beak cooling assembly. Preferably, the coolant flowing through the beak cooling assembly is water.

[0035] The beak forming mechanism of the present embodiment cools the beak by adding a beak cooling component, so that the beak 1 can be cooled in time after the plastic is formed at high temperature, and the cooling effect on the beak 1 is enhanced. The strength of the beak 1 is greater than 400N; the beak forming mechanism of the present embodiment cools the beak by adding a beak cooling component, which optimizes the molding quality and cycle of the beak 1 and avoids the shrinkage of the beak 1 and the quality abnormality of insufficient strength.

[0036] That is, the beak forming mechanism of the preferred technical solution of this embodiment, by adding a beak cooling component, solves the problem that the cooling water channel of the existing mold is far away from the beak 1, and has no cooling effect on the beak 1, resulting in poor cooling effect of the product's beak 1, causing shrinkage and quality abnormalities such as insufficient molding strength.

[0037] According to a preferred embodiment, the beak cooling assembly includes a first cooling passage and a second cooling passage 6, the first cooling passage and the second cooling passage 6 are connected to form a beak cooling circuit, such as Figure 2 Preferably, the first cooling passage includes a first passage 51 and a second passage 52, wherein the outlet end of the first passage 51 is connected to the inlet end of the second cooling passage 6, and the outlet end of the second cooling passage 6 is connected to the inlet end of the second passage 52, as shown in FIG. Figure 2 Preferably, the second cooling passage 6 is located below the beak accommodating portion, and the distance between the second cooling passage 6 and the beak 1 is short, so the beak 1 can be cooled in time by the coolant flowing through the second cooling passage 6 .

[0038] In the beak cooling assembly of the preferred technical solution of this embodiment, water flows through the first passage 51 and then flows through the second cooling passage 6. The beak 1 can be cooled by the coolant flowing through the second cooling passage 6, and then flows out from the second passage 52. The second cooling passage 6 of the preferred technical solution of this embodiment is located below the beak 1, which can enhance the cooling effect on the beak 1 of the product.

[0039] According to a preferred embodiment, the eagle beak cooling assembly further includes a blocking portion 7, such as Figure 2 Preferably, the blocking portion 7 is disposed on the air guide plate plane cooling passage between the first passage 51 and the second passage 52, and the first air guide plate plane cooling passage 81 located on one side of the blocking portion 7 is connected to the inlet end of the first passage 51, and the second air guide plate plane cooling passage 82 located on the other side of the blocking portion 7 is connected to the outlet end of the second passage 52, as shown in FIG. Figure 2 Preferably, the blocking portion 7 is copper blocking, that is, the blocking portion 7 is made of copper material.

[0040] The beak cooling assembly of the preferred technical solution of this embodiment further includes a blocking portion 7, which is arranged on the cooling passage of the air guide plate plane, and the cooling passage of the air guide plate plane is cut off by the blocking portion 7 and divided into a first cooling passage 81 of the air guide plate plane and a second cooling passage 82 of the air guide plate plane. That is, the blocking portion 7 can change the flow direction of the coolant flowing through the cooling passage of the air guide plate plane, so that the coolant flowing out of the first cooling passage 81 of the air guide plate plane passes through the first cooling passage and the second cooling passage 6, and then flows through the second cooling passage 82 of the air guide plate plane. Figure 2 The arrows in the figure show the coolant flow direction.

[0041] In the prior art, the coolant flows directly from the first air guide plate plane cooling passage 81 to the second air guide plate plane cooling passage 82. The beak cooling assembly of the preferred technical solution of this embodiment changes the flow direction of the coolant flowing out of the first air guide plate plane cooling passage 81 by setting the blocking portion 7. Specifically, the coolant flowing out of the first air guide plate plane cooling passage 81 flows to the first passage 51, the second cooling passage 6, and the second passage 52 before entering the second air guide plate plane cooling passage 82. That is, the beak cooling assembly of the preferred technical solution of this embodiment optimizes the molding quality and cycle of the beak 1.

[0042] According to a preferred embodiment, the first cooling passage is arranged in the movable mold plate, and the second cooling passage 6 is arranged in the movable mold insert 4. The first cooling passage of the preferred technical solution of this embodiment can also be called the first cooling water passage; the second cooling passage 6 can also be called the second cooling water passage. The first cooling passage of the preferred technical solution of this embodiment can also be called the movable mold plate water passage, and the second cooling passage 6 can also be called the movable mold insert water passage. Specifically, the first cooling passage is formed by drilling holes in the movable mold plate, and the second cooling passage 6 is formed by drilling holes in the movable mold insert 4.

[0043] According to a preferred embodiment, the first cooling passage further includes a third passage 53 and a fourth passage 54. Figure 2 As shown. Among them, the third passage 53 is connected to the first passage 51, the fourth passage 54 is connected to the second passage 52, and the ends of the third passage 53 and the fourth passage 54 away from the first passage 51 and the second passage 52 are in a blocked state. In the preferred technical solution of this embodiment, the ends of the third passage 53 and the fourth passage 54 away from the first passage 51 and the second passage 52 are in a blocked state, so that the coolant flowing out of the first air guide plate plane cooling passage 81 can flow into the first passage 51, and the coolant flowing out of the second passage 52 can flow into the second air guide plate plane cooling passage 82.

[0044] According to a preferred embodiment, the beak receiving portion is arranged on the movable mold insert 4, and the beak receiving portion is used for forming the beak 1. Preferably, the beak receiving portion is formed into a structure that independently contains the beak wall, such as Figure 3 Or as shown in 4. The preferred technical solution of this embodiment said that the beak accommodating part is formed as a structure that independently contains the beak wall, which means that the beak accommodating part covers the entire thickness of the beak wall, that is, the width of the beak accommodating part along the beak wall direction is equivalent to the wall thickness of the beak 1.

[0045] The beak forming mechanism of the preferred technical solution of this embodiment completely encompasses the beak wall through the beak accommodating portion on the movable mold insert 4, so that there is no parting line on the outer surface of the beak wall, thereby avoiding the quality risks of part assembly step difference and burrs on the parting line in the product beak 1; on the other hand, the beak wall is completely encompassed by the beak accommodating portion on the movable mold insert 4, so that the product beak 1 is formed in the movable mold insert 4, which effectively avoids the abnormal movement loss of the slider and can reduce the number of times the machine is taken offline for maintenance.

[0046] That is, the beak forming mechanism of the preferred technical solution of this embodiment completely encompasses the beak wall through the beak accommodating portion on the movable mold insert 4, thereby solving the technical problems in the prior art that the beak 1 produced by the beak forming mechanism has quality risks such as part assembly step difference and burrs on the parting line.

[0047] According to a preferred embodiment, the width of the beak accommodating portion is equivalent to the wall thickness of the beak 1. Preferably, the width of the beak accommodating portion is 4.012 mm. Since the width of the beak 1 is 4.012 mm, the width of the beak accommodating portion of the preferred technical solution of this embodiment is 4.012 mm, so that the width of the beak 1 after molding is 4.012 mm. The width of the beak accommodating portion mentioned in the preferred technical solution of this embodiment refers to the width inside the beak accommodating portion.

[0048] According to a preferred embodiment, the height of the upper end surface of the beak accommodating portion from the bottom of the beak 1 is 3.9-4.0 mm. The height of the upper end surface of the beak accommodating portion from the bottom of the beak 1 is 3.9-4.0 mm, which is a safety value to prevent the slider insert from driving the product beak 1 during movement.

[0049] The eagle beak forming mechanism of the preferred technical solution of this embodiment completely solves the problem of the eagle beak breakage of the air guide plate by adding a set of separate eagle beak cooling water channels and arranging an eagle beak accommodating portion on the movable mold insert 4 that independently contains the eagle beak wall. The eagle beak 1 has no quality problems such as shrinkage and burrs, which reduces the waste of raw materials and the poor utilization rate of the machine, reduces the waste of production costs caused by defective products and the problem of after-sales quality complaints; and can also reduce the number of times the mold is taken off the machine for maintenance, so as to improve the stable output of the product.
