For example, in places with relatively harsh working environments such as highways, bridges, buildings, aquaculture ponds, underground projects, and emergency excavations, in order to avoid the influence of the harsh environment on the operation of the personnel inside the cab, a covering part is usually provided on the excavator.

[0003] The existing Chinese patent document CN202022530025.6 is an excavator cab top cover mold. It relates to the technical field of molds. It has a reasonable structure and can reliably blow out sundries to ensure the cavity cleanliness. It includes an upper die base and a lower die base. A punching head is provided at the bottom of the upper die base, a cavity is provided at the top of the lower die base, a receiving groove is also provided at the top of the lower die base, a cover plate is adaptively provided at the notch of the receiving groove, and a cover plate driving device is provided below the cover plate in the receiving groove. The cover plate driving device includes a linear lifting mechanism and a rotating mechanism; the rotating mechanism includes a motor, and the output shaft of the motor is fixedly connected to the bottom of the cover plate; the linear lifting mechanism includes a support plate and a hydraulic cylinder. The motor is provided on the top of the support plate, the hydraulic cylinder is provided at the bottom of the receiving groove, and the push rod of the hydraulic cylinder pushes the support plate; an air passage is also provided in the lower die base, one end of the air passage communicates with the receiving groove, and the other end communicates with a gas source.

[0004] However, there are certain defects when the above patent is used. The device does not have a material lifting mechanism, and it is necessary to manually take out the punched top cover from the mold. Since the top cover is large in volume and heavy in weight, it is time-consuming and laborious, affecting the work efficiency.

[0005] Therefore, an excavator top cover mold is proposed here to solve the above problems. Summary of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides an excavator top cover mold.

[0007] The utility model is realized by adopting the following technical solutions:

[0008] An excavator top cover mold includes a base, support columns, a cross beam, a computer control box, and a lower mold. There are four support columns fixed on the upper surface of the base. The cross beam is fixed at the upper end of each support column. The lower mold is fixed on the base. The computer control box is fixed on the support columns. There is a mold cavity in the lower mold. An electric hydraulic telescopic cylinder is provided at the lower end of the cross beam, fixed on the lower surface of the cross beam, above the lower mold. The output end of the electric hydraulic telescopic cylinder is provided with a connecting plate. A connecting rod is fixedly provided on the lower surface of the connecting plate. A material lifting device is provided at the lower end of the connecting rod. The material lifting device is used to take out the top cover from the lower mold. A punching head is fixedly provided at the lower end of the material lifting device.

[0009] Through the above technical solution, the punched top cover can be taken out from the lower mold cavity of the lower mold by using the material lifting device, without manual handling, greatly reducing the labor intensity of workers and improving work efficiency.

[0010] The material lifting device includes a fixing plate fixed at the lower end of the connecting rod. A material lifting motor is fixedly provided on the left side of the fixing plate. A moving shaft is provided at the output end of the material lifting motor. Threads are provided on both sides of the moving shaft. A clamping arm is sleeved on the moving shaft. There are two clamping arms standing opposite each other.

[0011] Through the above technical solution, the rotation of the material lifting motor drives the rotation of the rotating shaft, and the thread directions at both ends of the rotating shaft are opposite. Therefore, the clamping arms sleeved on the rotating shaft can move axially towards the central part. The clamping arms are in an "L" shape and can just clamp the top cover, and the electric hydraulic telescopic cylinder is used to take it out of the lower mold cavity, saving manpower.

[0012] Fixed blocks are provided on both sides of the lower end of the fixing plate. A guide rod is provided between the fixed blocks. The guide rod penetrates through the clamping arm and the punching head.

[0013] Through the above technical solution, the guide rod limits the clamping arm to ensure that the clamping arm moves axially.

[0014] A moving device is also provided on the cross beam. The moving device includes a moving motor, a rotating shaft, a sliding sleeve, and a bearing. The moving motor is fixed on the left side wall of the cross beam. The rotating shaft is fixed at the output end of the moving motor. The bearing is fixed on the right inner wall of the cross beam. The sliding sleeve is sleeved on the rotating shaft. External threads are provided on the rotating shaft. The sliding sleeve can move left and right on the rotating shaft.

[0015] Through the above technical solution, the top cover taken out from the lower mold cavity can be moved to the side by using the moving device and placed down for transportation, improving work efficiency.

[0016] A sliding rod is provided between the support columns. The sliding rod penetrates through the lower end of the sliding sleeve.

[0017] Through the above technical solution, the sliding rod ensures that the moving device moves left and right along the sliding rod without deviation.

[0018] The utility model has the following beneficial effects compared with the prior art:

[0019] By setting up a material lifting device, the material lifting motor on the material lifting device rotates to drive the rotating shaft to rotate. The thread directions at both ends of the rotating shaft are opposite, so that the clamping arms sleeved on the rotating shaft can move axially towards the central part. The clamping arms are in an "L" shape and can just clamp the top cover. The electric hydraulic telescopic cylinder is used to take it out of the lower die cavity without manual handling, greatly reducing the labor intensity of workers and improving work efficiency.
