Description

Technical Field

[0001] This invention relates to the field of oil pump housing technology, and more specifically, to a molding device for an engine oil pump housing. Background Technology

[0002] The oil pump is used to pressurize the oil in the oil pan to the filter, ensuring that the oil, after passing through the filter, can still be reliably delivered to various lubrication channels and friction surfaces of moving parts. When the engine is running, the oil pump works continuously to ensure the oil circulates continuously in the lubrication circuit. In the known published patent CN202322433196.0, a die-casting mold for assisting in the forming of an oil pump housing is mentioned. The oil pump housing is an important component of the oil pump. As shown in the figure, the oil pump housing includes a housing body 31, which has a main chamber 32 and a secondary chamber 33. The main chamber 32 and the secondary chamber 33 have shaft holes 34. The secondary chamber 33 is generally long and tubular. Multiple channels 35 are arranged around the secondary chamber 33 in the housing body 31. A small hole 36 is opened on the left side of the main chamber 32 in the housing body 31. The entire oil pump housing is relatively difficult to form.

[0003] Therefore, it is necessary to provide a molding device for an engine oil pump housing to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a molding device for an engine oil pump housing, which facilitates molding and improves product qualification rate.

[0005] The technical solution adopted by this application to solve its technical problem is: a molding device for an engine oil pump housing, including a base, a bracket fixedly installed on the upper end of the base, limit baffles fixedly installed on both sides of the bracket, a connecting platform fixedly installed on the upper end of the bracket, a storage slot fixedly installed on the upper end of the connecting platform, a control panel fixedly installed on the front end of the bracket, a molding assembly provided at the lower end of the storage slot, and a molding assembly provided on the inner side of the limit baffles.

[0006] Furthermore, the injection molding assembly includes a hydraulic cylinder, which is fixedly installed in the middle section of the storage groove. A piston rod is fixedly installed at the lower end of the hydraulic cylinder, and an injection platform is fixedly installed at the lower end of the piston rod. An injection pipe is connected to the lower end of the injection platform.

[0007] Furthermore, the casting mold assembly includes a telescopic cylinder, which is fixedly installed on both sides of the limiting baffle. A threaded telescopic rod is fixedly installed at the front end of the telescopic cylinder, and a clamping plate is fixedly installed at the front end of the threaded telescopic rod. A mold groove is engaged on the inner side of the clamping plate, and an injection hole is opened at the upper end of the clamping plate.

[0008] Furthermore, rotating disks are fixedly installed on both sides of the inner wall of the limiting baffle, and the rotating disks are fixedly connected to the threaded telescopic rod.

[0009] Furthermore, fixing buckles are fixedly installed on both sides of the limiting baffle and the clamping plate, and a telescopic rod is fixedly installed at the front end of the fixing buckle.

[0010] Furthermore, a sand storage tank is fixedly installed on the upper end of the base.

[0011] The beneficial effects of this utility model are: the threaded telescopic rod and the extension of the telescopic rod drive the clamping plate at the front end to move forward. When the telescopic rod extends to half of the threaded telescopic rod, it will stop extending and disengage from the fixing buckle on the clamping plate. The threaded telescopic rod continues to drive the clamping plate to move inward until the two clamping plates are closed together. Through the above steps, the molding device can be adapted to a variety of molds. Through bidirectional pneumatic clamping, the stability of core making can be improved more effectively.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.

[0020] like Figure 1-3 As shown, this application provides a molding device for an engine oil pump housing, including a base 1, a bracket 2 fixedly installed on the upper end of the base 1, limit baffles 8 fixedly installed on both sides of the bracket 2, a connecting platform 3 fixedly installed on the upper end of the bracket 2, a storage slot 14 fixedly installed on the upper end of the connecting platform 3, a control panel 15 fixedly installed on the front end of the bracket 2, an injection molding assembly provided at the lower end of the storage slot 14, and a molding assembly provided on the inner side of the limit baffles 8.

[0021] The injection molding assembly includes a hydraulic cylinder 4, which is fixedly installed in the middle section of the storage slot 14. A piston rod 6 is fixedly installed at the lower end of the hydraulic cylinder 4, and an injection platform 5 is fixedly installed at the lower end of the piston rod 6. An injection pipe 7 is connected to the lower end of the injection platform 5.

[0022] The mold assembly includes a telescopic cylinder 10, which is fixedly installed on both sides of the limiting baffle 8. A threaded telescopic rod 19 is fixedly installed at the front end of the telescopic cylinder 10, and a clamping plate 11 is fixedly installed at the front end of the threaded telescopic rod 19. A mold groove 12 is engaged on the inner side of the clamping plate 11, and an injection hole 13 is opened at the upper end of the clamping plate 11.

[0023] Rotary discs 18 are fixedly installed on both sides of the inner wall of the limiting baffle 8, and the rotating discs 18 are fixedly connected to the threaded telescopic rod 19.

[0024] The limiting baffle 8 and the clamping plate 11 are fixedly installed with fixing buckles 17 on both sides, and the front end of the fixing buckle 17 is fixedly installed with a telescopic rod 9.

[0025] A sand storage tank 16 is fixedly installed on the upper end of the base 1.

[0026] Specifically, when the device is first put into use, the operator first replaces the mold slot 12 with a trial-fit oil pump housing mold. After the replacement is completed, the operator activates the telescopic cylinders 10 on both sides of the limit baffle 8 through the control panel 15. The telescopic cylinders 10 are activated to absorb external air, which drives the threaded telescopic rod 19 and telescopic rod 9 at the front end to extend forward. The threaded telescopic rod 19 and telescopic rod 9 extend forward, which drives the clamping plate 11 at the front end to move forward. When the telescopic rod 9 extends to half of the threaded telescopic rod 19, it will stop extending and disengage from the fixing buckle 17 on the clamping plate 11. The threaded telescopic rod 19 continues to drive the clamping plate 11 to move inward until the two clamping plates 11 are closed together. Through the above steps, the molding device can be adapted to various molds. Through bidirectional air pressure clamping, the stability of core making can be improved more effectively.

[0027] When the clamping plates 11 are closed, the worker pours the sand to be cast into the injection platform 5 through the storage groove 14. At this time, the worker starts the hydraulic cylinder 4 through the control panel 15. The hydraulic cylinder 4 drives the lower piston rod 6 to extend downward. The downward extension of the piston rod 6 drives the injection platform 5 to move downward. The downward movement of the injection platform 5 drives the lower injection pipe 7 to extend into the injection hole 13 at the upper end of the clamping plate 11. Then, the casting material is poured into the clamping plate 11 through the storage groove 14. Through the above steps, the casting of the shell can be completed more efficiently.

[0028] After all steps are completed, wait for the mold to cool. After cooling, the operator starts the hydraulic cylinder 4 through the control panel 15 to drive the piston rod 6 to move the injection platform 5 upward. After the injection platform 5 moves upward, start the rotating disks 18 on both sides of the limit baffle 8. The rotating disks 18 start to drive the threaded telescopic rod 19 to rotate. The rotation of the threaded telescopic rod 19 drives the clamping plate 11 at the front end to rotate 180° to flip it over. After the clamping plate 11 flips over, the excess sand inside will be poured out through the injection hole 13 into the sand storage tank 16 at the top of the base 1. Finally, the clamping plate 11 is released and the shell of the mold inside the clamping plate 11 is taken out.
