[0001] The utility model relates to the technical field of injection molds, in particular to a novel automobile fan cover injection mold. Background Art

[0002] The protective cover on the car fan is used to protect the front end of the fan, helping to guide the air flow and maintain the stability of the entire cooling system. It is usually a plastic product and is formed by injection molding.

[0003] The automobile fan cover injection molding device consists of a movable mold and a fixed mold. The movable mold is connected to the injection pipe and moved by the driving part. The hot melt plastic is transported to the closed fixed mold and the internal mold cavity of the movable mold through the injection pipe, and cooled and formed. However, during the demolding process after the fan cover is processed, the fan cover will have strong adhesion to the fixed mold. Manual demolding is not only laborious, but also the hands move at the movable mold, which poses a safety hazard. For this reason, we propose a new type of automobile fan cover injection mold to solve the existing problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 5As shown, a novel automobile fan cover injection mold proposed by the utility model comprises a base 1, a mounting frame 2, a turntable 3, a fixed mold 7, a sliding seat 10 and a push rod 14. A turntable 3 is arranged above the base 1, a reduction motor body is arranged at the upper end of the base 1, and the output end of the upper end of the reduction motor is connected to the center position of the lower end of the turntable 3. The turntable 3 is provided with a fixed mold 7 distributed in a circular array. The front and rear ends of the fixed mold 7 are provided with a mounting shaft 16 rotatably mounted inside the turntable 3. The outer wall of the mounting shaft 16 is sleeved with a torsion spring 17. The two ends of the torsion spring 17 are respectively connected to the fixed mold 7 and the inner wall of the turntable 3. The turntable 3 is provided with equidistant placement grooves, and the fixed molds 7 are all located inside the placement grooves. The lower end of the turntable 3 is provided with equidistant support plates 18, and the upper end of the support plate 18 is in contact with one side of the lower end of the fixed mold 7. The upper end of the base 1 is provided with an injection structure 8, and the injection structure 8 includes a longitudinal drive rod, a movable mold and an injection pipe. A hydraulic rod 5 is provided at the end, an extrusion plate 6 is provided at the telescopic end of the hydraulic rod 5, a bracket 4 is sleeved on the outer wall of the hydraulic rod 5, one side of the lower end of the bracket 4 is connected to the upper end of the base 1, a mounting frame 2 is provided on the upper end of the base 1, a motor 11 is provided on the upper end of the mounting frame 2, a gear 21 is provided on the output end of the motor 11, a sliding seat 10 is provided on the upper end of the mounting frame 2, an arc plate 9 is rotatably installed inside the sliding seat 10, the center of the arc plate 9 is consistent with the axis of the mounting shaft 16, and a gear ring is sleeved on the outer wall of the arc plate 9 20. A mounting block 22 is provided on the inner wall of the arc plate 9, and a connecting block 12 is provided on the outer wall of one side of the fixed mold 7. The mounting block 22 corresponds to the connecting block 12. A push rod 14 is slidably installed inside the fixed mold 7. A push block 19 is provided on the upper end of the push rod 14. A groove adapted to the push block 19 is provided inside the upper end of the fixed mold 7. A spring 15 is sleeved on the outer side of the lower end of the push rod 14. A fixed plate 13 is provided at the lower end of the push rod 14. The upper and lower ends of the spring 15 are connected to the fixed plate 13 of the fixed mold 7.

[0022] Based on the implementation steps of Example 1: the longitudinal driving rod of the injection molding structure 8 drives the movable mold to descend, and the movable mold is docked with the fixed mold 7 corresponding to the lower end, and then the injection pipe conveys the hot melt liquid material to the mold cavity closed by the fixed mold 7 and the movable mold, and the hot melt raw material is filled in the mold cavity. After cooling, the movable mold is lifted, and then the reduction motor drives the turntable 3 to rotate, and the unused fixed mold 7 is re-aligned with the lower end of the movable mold;

[0023] When the fixed mold 7 with undemolded residue inside rotates to the bottom of the sliding seat 10, the motor 11 drives the gear 21 to push the ring gear 20. When the ring gear 20 rotates, it drives the mounting block 22 to squeeze the connecting block 12. After the fixed mold 7 is squeezed, it rotates with the mounting shaft 16 as the axis, and squeezes the torsion spring 17 at the same time. When the fixed mold 7 rotates ninety degrees, the hydraulic rod 5 drives the extrusion plate 6 to move laterally, pressurizes the corresponding fixed plate 13, and the fixed plate 13 is forced to squeeze the spring 15. By squeezing the ejector rod 14 and the ejector block 19, the ejector block 19 applies force to the lower end of the automobile fan blank cover inside the fixed mold 7, so that the automobile fan blank adhered to the inside of the fixed mold 7 is ejected, and the automobile fan blank is automatically demolded. During the demolding process, the injection molding structure 8 is simultaneously subjected to a new injection molding process, which improves the processing efficiency. During the demolding process, the staff is prevented from being active at the injection molding structure 8, and the operating errors are avoided, and the hands are prevented from being crushed by the movable mold that is mistakenly started.

[0024] After the hydraulic rod 5 is reset, the fixed plate 13 is elastically supported by the spring 15, driving the ejector rod 14 and the ejector block 19 to reset, thereby ensuring the effective use of the fixed mold 7 again. The motor 11 drives the gear 21 to rotate in the opposite direction, and the gear ring 20 is pushed in the opposite direction to reset. The mounting block 22 ends the extrusion of the connecting block 12. The mounting shaft 16 loses the extrusion of the fixed mold 7, and is driven to reset through the torsional elastic support of the torsion spring 17. The opening of the fixed mold 7 faces upward, and is effectively docked with the movable mold, thereby realizing automatic demoulding of the automobile fan cover after processing.
