Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a two-in-one pressing fixture for mold parts processing. Background Art

[0002] A two-in-one pressing fixture is usually a device used for mold parts processing to improve production efficiency and reduce production cycle. It is necessary to select a suitable two-in-one pressing fixture according to specific production needs and parts processing requirements to ensure that it can effectively meet production requirements.

[0003] For example, a two-in-one pressing jig for processing mold parts disclosed in the authorization announcement number CN213261299U includes a jig seat, screws are arranged on both sides of the jig seat, adjusting nuts are arranged on the annular surface of the screws, a cross bar is arranged between the two groups of screws, an upper template is arranged below the cross bar, a beam gauge is arranged on both sides of the upper template, an upper mold core is arranged at the bottom end of the upper template, a lower template is arranged at the upper end of the jig seat, and the outer two sides of the lower template are arranged on the sensing parts. After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the horizontality of the two-in-one pressing jig can be calibrated, thereby improving the high precision of the pressing of mold parts, and the convenience of the pressing jig to remove the molded parts can be achieved, thereby preventing workers from taking out the workpieces by themselves, which may cause scalding problems, and improving safety.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] However, the above patent has the following shortcomings:

[0006] After the above-mentioned two-in-one pressing fixture presses the workpiece, due to the small gap between the upper and lower molds during pressing, the workpiece will be tightly stuck in the shaping groove of the lower mold after pressing. When the ejector block lifts the workpiece, the workpiece is easily stuck, and the outer surface of the workpiece is easily worn while lifting it with force, resulting in errors in the accuracy of the workpiece after pressing.

[0028] In this embodiment, the first push rod motor 8 is started, and the first push rod motor 8 pushes the clamping plate 401 forward after starting. When the two clamping plates 401 move in the same direction, they push the top block 402 at the bottom, and the top block 402 is received into the telescopic slot 7. At the same time, the top block 402 will compress the first spring 403, and then the workpiece to be pressed is placed on the top of the lower mold 3, and then the workpiece is pressed into shape through the lower mold 3 and the upper mold 5. When the workpiece is formed, the first push rod motor 8 is controlled to retract the clamping plate 401 from the two side surfaces of the workpiece. At this time, the compressed first spring 403 will lift the top block 402 to eject the workpiece, so that the material can be unloaded quickly without causing wear to the workpiece.

[0029] like Figure 3 As shown, second electric push rods 601 are fixedly installed on the outside of both sides of the upper mold 5, and clamping strips 602 are arranged at one end of the two second electric push rods 601 located inside the upper mold 5. A pressing block 603 is arranged in the middle of the upper mold 5, and strip grooves 10 matching the clamping strips 602 are opened on the outer walls of both sides of the pressing block 603;

[0030] In this embodiment, when the pressure block 603 needs to be replaced, the second electric push rod 601 is first started, and the clamping strip 602 is withdrawn from the strip grooves 10 on both sides of the pressure block 603 by the second electric push rod 601. Then, the pressure block 603 can be quickly removed from the bottom of the upper mold 5, and then the pressure block 603 of other specifications is replaced and put in, and the first push rod motor 8 is controlled to start, and the first push rod motor 8 pushes the clamping strip 602 forward to clamp it into the strip groove 10 and fix it.

[0035] Working principle: During processing, first start the first push rod motor 8, and then push the clamping plate 401 forward after starting. When the two clamping plates 401 move in the same direction, they push the top block 402 at the bottom, and put the top block 402 into the telescopic slot 7. At the same time, the top block 402 will compress the first spring 403, and then place the workpiece to be pressed on the top of the lower mold 3, and then press the workpiece into shape through the lower mold 3 and the upper mold 5. When the workpiece is formed, control the first push rod motor 8 to retract the clamping plate 401 from the two side surfaces of the workpiece. At this time, the compressed first spring 403 will lift the ejector block 402 to eject the workpiece. When the pressure block 603 needs to be replaced, the second electric push rod 601 is first started, and the clamping strip 602 is withdrawn from the strip grooves 10 on both sides of the pressure block 603 through the second electric push rod 601. Then, the pressure block 603 can be quickly removed from the bottom of the upper mold 5, and then other specifications of the pressure block 603 are replaced and put in. Then, the first push rod motor 8 is controlled to start, and the first push rod motor 8 pushes the clamping strip 602 forward to clamp it into the strip groove 10 and fix it.
