Technical Field

[0001] The utility model belongs to the technical field of mold withdrawal and mold closing, in particular to a mold withdrawal and mold closing device. Background Art

[0002] The mold clamping device generally includes mechanical mold clamping device, hydraulic mold clamping device, pneumatic mold clamping device, electric mold clamping device and hydraulic-electric mold clamping device. Its function is to drive the mold to close and perform die casting, injection molding, extrusion and other molding processes on materials such as plastics, rubber, and glass. The mold ejection device is a device that removes the mold from the injection molding machine or performs other operations after the mold is opened. The mold ejection device generally includes mechanical mold ejection device and hydraulic mold ejection device.

[0003] After the template is closed, the material can be stamped and shaped. After the material is shaped, it needs to be demolded. At this time, the stamping equipment needs to be reset upward so that the staff can re-add material to the cavity. At this time, if the top hydraulic rod fails or the start switch of the hydraulic rod is accidentally touched, the upper template and the mold base may accidentally fall down, which may cause injuries to the staff. There are safety hazards and poor safety.

[0004] For this purpose, a mold plate withdrawing and mold plate closing device is proposed. Utility Model Content

[0005] The purpose of the utility model is to prevent the stamping template from deflecting when the stamping template is closed and to improve the safety of the stamping template after the stamping template is withdrawn. The application provides a withdrawing template and a closing template device.

[0009] Furthermore, the anti-slip mechanism includes an electric cylinder, which is fixedly connected to the inner bottom surface of the side groove 1, and a piston rod is installed at the output end of the electric cylinder, and an interception plate is fixedly connected to one end of the piston rod away from the electric cylinder.

[0010] Furthermore, a rubber pad is bonded to the upper surface of the intercepting plate, and a plurality of deformation holes are opened inside the rubber pad.

[0011] Furthermore, the upper surfaces of the lower die base on both sides of the cavity are fixedly connected, the end away from the lower die base is fixedly connected to the lower surface of the top plate, and the two ends of the upper die base are slidably connected to the outer surface.

[0012] Furthermore, the lower surface of the intercepting plate and the inner bottom surface of the second side groove are on the same horizontal plane.

[0015] 1. In the utility model, when the material is closed and stamped, the material to be stamped can be placed inside the cavity first, and then the hydraulic cylinder can be started to make the lifting column drive the upper die base and the stamping template to move downward until the stamping template enters the cavity to stamp the material. When the stamping is completed, the hydraulic cylinder can be started to make the lifting column drive the upper die base and the stamping template to reset. In this process, the upper die base will also slide up and down on the inner surface of the slide groove through the slide plate, thereby guiding the movement trajectory of the upper die base, thereby avoiding the upper die base and the stamping template from offsetting when the mold is closed and the mold is withdrawn.

[0016] 2. In the utility model, after the upper die seat and the stamping template are reset upward, starting the electric cylinder can cause the piston rod to drive the intercepting plate to move into the side groove 2 until the intercepting plate overlaps the inner bottom surface of the side groove 2. At this time, the intercepting plate and the rubber pad can intercept the slide plate that slides downward accidentally, thereby preventing the upper die seat and the stamping template from falling due to accidental start-up or failure of the hydraulic cylinder, thereby improving the safety of the staff when adding materials into the cavity.

The end of the lowering column 42 away from the hydraulic cylinder 41 is fixedly connected to the upper die base 43, the lower surface of the upper die base 43 is installed with a stamping template 44, the two side surfaces of the upper die base 43 are fixedly connected with slides 45, and the input end of the hydraulic cylinder 41 is electrically connected to an external power supply; specifically, the hydraulic cylinder 41 is started to make the lifting column 42 drive the upper die base 43 and the stamping template 44 to move downward until the stamping template 44 enters the cavity 11 to stamp the material. When the stamping is completed, the hydraulic cylinder 41 can be started to make the lifting column 42 drive the upper die base 43 and the stamping template 44 to reset.

[0025] Reference Figure 1-Figure 5There are two side plates 2, and a slide groove 21 is provided on the side surface where the two side plates 2 are close to each other. The outer surface of the end of the slide plate 45 away from the upper mold base 43 is slidably connected to the inner surface of the slide groove 21; specifically, during this stamping process, the upper mold base 43 will also slide up and down on the inner surface of the slide groove 21 through the slide plate 45, and the upper mold base 43 will also slide up and down along 6, thereby guiding the movement trajectory of the upper mold base 43, thereby avoiding the upper mold base 43 and the stamping template 44 from offset when the mold is closed and released.

[0026] Reference Figure 1-Figure 5 A side groove 1 22 is provided on the inner wall of one side of the slide groove 21, and a side groove 23 is provided on the inner wall of the other side of the slide groove 21. An anti-skid mechanism 5 is installed on the inner bottom surface of the side groove 1 22. The anti-skid mechanism 5 includes an electric cylinder 51. The electric cylinder 51 is fixedly connected to the inner bottom surface of the side groove 1 22. A piston rod 52 is installed on the output end of the electric cylinder 51. An end of the piston rod 52 away from the electric cylinder 51 is fixedly connected to an interception plate 53. A rubber pad 54 is bonded to the upper surface of the interception plate 53.

[0028] The implementation principle of an embodiment of a mold plate withdrawing and closing device of the present application is as follows:

[0029] When using the equipment, first connect to an external power source. When the material is closed and stamped, the material to be stamped can be placed inside the cavity 11 first, and then the hydraulic cylinder 41 can be started to make the lifting column 42 drive the upper die base 43 and the stamping template 44 to move downward until the stamping template 44 enters the cavity 11 to stamp the material. When the stamping is completed, the hydraulic cylinder 41 can be started to make the lifting column 42 drive the upper die base 43 and the stamping template 44 to reset. In this process, the upper die base 43 will also slide up and down on the inner surface of the slide groove 21 through the slide plate 45, and the upper die base 43 will also slide up and down along 6, thereby guiding the movement trajectory of the upper die base 43, thereby avoiding the upper die base 43 and the stamping template 44 from offset when the mold is closed and the mold is withdrawn.

[0030] When the upper die base 43 and the stamping template 44 are reset upward, starting the electric cylinder 51 can make the piston rod 52 drive the intercepting plate 53 to move into the side groove 23 until the intercepting plate 53 overlaps the inner bottom surface of the side groove 23. At this time, the intercepting plate 53 and the rubber pad 54 can intercept the slide plate 45 that accidentally slides downward, thereby preventing the upper die base 43 and the stamping template 44 from falling due to accidental start-up or failure of the hydraulic cylinder 41, thereby improving the safety of the staff when adding materials into the cavity 11.
