Description

Technical Field

[0001] The utility model relates to the technical field of engine bracket casting, in particular to a pouring device for engine bracket castings. Background Art

[0002] Automobile engine bracket castings are one of the important components of the engine mounting system. Engine bracket castings produced by die-casting process have precise dimensions, excellent mechanical properties, dense internal structure, and can be mass-produced. Therefore, they can be used to manufacture engine bracket castings.

[0003] Chinese Patent Grant Publication No. CN206716960U discloses a hybrid pouring device for bracket castings, including a template. A pouring cup is arranged on the upper part of the template. A plurality of bracket patterns are arranged on the template. The template and the bracket patterns are connected and communicated through a cross-riser. The cross-riser is divided into a horizontal cross-riser and a vertical cross-riser. The bracket pattern is externally connected with a riser. The riser and the bracket pattern are connected and communicated through a riser neck. The riser is externally connected with the horizontal cross-riser. The riser and the horizontal cross-riser are connected and communicated through a lap joint; the pouring channel of this utility model has good slag avoidance effect and high qualified rate of castings; the filling is stable and smooth, reducing sand washing defects and improving the qualified rate of castings.

[0004] By referring to the above comparative documents, it can be seen that the prior art still has the following deficiencies. Generally, the engine bracket casting is formed by pouring through a pouring mold. However, after the hot-melted material is poured into the bracket forming cavity, the hot-melted material is prone to uneven distribution inside, resulting in poor pouring quality of the engine bracket casting. Moreover, the hot-melted material generally remains in the pouring channel. Since it is difficult to clean the inside of the pouring channel, after long-term use, after the hot-melted material cools and solidifies, the inside of the pouring channel is prone to blockage, which will affect the pouring smoothness. Summary of the Utility Model

[0005] The utility model provides a pouring device for engine bracket castings, which is beneficial to ensuring the pouring quality of engine bracket castings and is convenient for cleaning and dredging the pouring channel to ensure the pouring smoothness.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] The casting mold is provided with a bracket forming cavity, and a pouring channel communicating with the bracket forming cavity is opened at the upper end of the casting mold. Fixed plates are respectively fixed on the left and right sides of the inner bottom end of the frame. A guide rod is fixed between the two fixed plates. The left and right ends of the periphery of the guide rod are slidably sleeved with sliding plates. Return springs are connected between the sliding plates and the adjacent fixed plates. Semi-circular blocks are respectively fixed at the lower ends of the inner sides of the sliding plates. An oscillation driving assembly is arranged at the inner bottom end of the frame;

[0009] Two scraping plates are arranged at the upper end of the casting mold.

[0010] Further, the oscillation driving assembly includes a driving motor and an impact ball. The driving motor is fixed at the inner bottom end of the frame, and a linkage rod is connected to the power end of the driving motor.

[0011] Further, the lower end of the casting mold is fixed with a support plate by bolts, and the upper ends of the sliding plates are fixed to the lower end of the support plate.

[0012] Further, an electric cylinder is fixed at the inner top end of the frame. A rotating motor is connected to the power end of the electric cylinder, and a rotating shaft is connected to the power end of the rotating motor.

[0013] Further, the scraping plates are located on both sides of the rotating shaft, and two spring return rods distributed up and down are respectively connected between the scraping plates and the rotating shaft.

[0014] Further, the scraping plates correspond to the pouring channel up and down, and the lower ends of the scraping plates are inclined. The inner diameter of the pouring channel is larger than the distance between the two scraping plates.

[0015] The beneficial effects of the present utility model:

Specific implementation mode

[0023] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the implementation mode does not limit the present utility model.

[0024] As Figure 1 shown, in this embodiment, it includes a frame 1 and a casting mold 2. The casting mold 2 is arranged at the lower end inside the frame 1. A support forming cavity 3 is opened in the casting mold 2, and a pouring channel 4 communicating with the support forming cavity 3 is opened at the upper end of the casting mold 2. Fixed plates 6 are fixed on both the left and right sides of the bottom end inside the frame 1. A guide rod 8 is fixed between the two fixed plates 6. Sliding plates 7 are slidably sleeved on the left and right ends of the periphery of the guide rod 8. Return springs 9 are connected between the sliding plates 7 and the adjacent fixed plates 6. Semi-circular blocks 12 are fixed at the lower ends of the inner sides of the sliding plates 7. An oscillation driving assembly is arranged at the bottom end inside the frame 1. The oscillation driving assembly includes a driving motor 10 and an impact ball 11. The driving motor 10 is fixed at the bottom end inside the frame 1, and a connecting rod is connected to the power end of the driving motor 10. The impact ball 11 is fixed at the end of the connecting rod, and the impact ball 11 corresponds to the semi-circular block 12. The lower end of the casting mold 2 is fixed with a support plate 5 by bolts. The upper ends of the sliding plates 7 are fixed to the lower end of the support plate 5.

[0025] After injecting the hot molten material into the support forming cavity 3 through the pouring channel 4, the driving motor 10 works to drive the connecting rod and the impact ball 11 to rotate. The impact ball 11 continuously impacts the semi-circular block 12, so as to push the sliding plate 7 to slide along the guide rod 8 outwards. At the same time, the sliding plate 7 will compress the return spring 9. After the impact ball 11 moves away from the semi-circular block 12, the elastic force of the return spring 9 drives the sliding plate 7 to slide inwards along the guide rod 8 to reset. In summary, when the sliding plate 7 moves left and right, it will drive the support plate 5 and the casting mold 2 to reciprocate left and right. Therefore, it is beneficial to oscillate the hot molten material in the support forming cavity 3, so that the hot molten material can be evenly distributed in the support forming cavity 3, effectively ensuring the casting quality of the engine support casting.

[0026] As Figures 1-3As shown in the figure, in this embodiment, two scraping plates 14 are provided at the upper end of the casting mold 2. A power cylinder 13 is fixed to the inner top end of the frame 1. The power end of the power cylinder 13 is connected to a rotating motor 15. The power end of the rotating motor 15 is connected to a rotating shaft 16. The scraping plates 14 are located on both sides of the rotating shaft 16, and two spring return rods 17 distributed vertically are connected between the scraping plates 14 and the rotating shaft 16. The scraping plates 14 correspond to the casting channel 4 up and down, and the lower end of the scraping plate 14 is inclined. The inner diameter of the casting channel 4 is larger than the distance between the two scraping plates 14.

[0027] When it is necessary to clean the casting channel 4, the power cylinder 13 extends to drive the rotating motor 15, the rotating shaft 16, the spring return rods 17 and the scraping plates 14 to move downward. Since the distance between the two scraping plates 14 is smaller than the inner diameter of the casting channel 4, the scraping plates 14 are inserted into the casting channel 4 through the inclined surface at their lower ends. During this process, the opening of the casting channel 4 will push the scraping plates 14 inward along the inclined surface of the scraping plates 14, and the scraping plates 14 will compress the spring return rods 17, so that the two scraping plates 14 can be smoothly inserted into the casting channel 4. The elastic force of the spring return rods 17 will drive the scraping plates 14 to be tightened against the inner wall of the casting channel 4. Then, the rotating motor 15 works to drive the rotating shaft 16, the spring return rods 17 and the scraping plates 14 to rotate, which is beneficial to rotating and scraping the inner wall of the casting channel 4, and is also beneficial to conveniently cleaning the hot-melted materials adhered to the inner wall of the casting channel 4, thus avoiding the situation that the casting channel 4 is blocked due to the solidification of the hot-melted materials, and effectively ensuring the smoothness of casting.

[0028] As Figure 1 As shown in the figure, in this embodiment, a support plate 5 is fixed to the lower end of the casting mold 2 by bolts. The upper end of the sliding plate 7 is fixed to the lower end of the support plate 5.

[0029] The casting mold 2 is fixed to the support plate 5 by bolts. Therefore, by disassembling and assembling the bolts, the effect of disassembling and assembling the casting mold 2 can be achieved, and the casting mold 2 of other specifications can be conveniently replaced. Therefore, the hot-melted materials in the casting molds 2 of various specifications can be oscillated evenly, ensuring the applicability of the device.

[0030] All the technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiment is a preferred implementation scheme of the present invention. In addition, there are other implementation manners. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
