Description

Notebook pivot support frame plastic frock

Technical Field

The utility model relates to a plastic frock field, concretely relates to notebook pivot support frame plastic frock.

Background

The metal powder injection molding (MIM) is a new molding technology which is rapidly developed internationally in recent years, and has the advantages that the method is suitable for mass production of metal part products with precision, complex three-dimensional shapes and special performance requirements, and the molded and sintered products have not only the same complex shapes and high precision as those of products obtained by a plastic injection molding method, but also the physical, chemical and mechanical properties close to those of forged pieces.

The general process flow is as follows: the selected powder is mixed with a binder and the feedstock is then granulated and injected into the desired shape. After forming, the binder is removed, and the degreased blank is sintered. Sintering is a high temperature process that strengthens and compacts the formed powder blank, directly affecting the quality of the product.

Due to the influence of factors such as heating speed, sintering temperature and time, cooling speed, sintering atmosphere, sintering pressurization condition and the like in the sintering process, stress release occurs, and the sintered part has adverse reactions such as size deviation, deformation and the like.

For parts with high precision requirements, if products cannot meet the size requirements, the phenomena of incapability of installation, clamping or loosening after installation and the like can occur. Although the problem of product deformation is solved by the shaping tool developed before, the product is seriously out of tolerance in size after the sintering process, and the shaping tool can generate large crushing damage when controlling the size, so that the product is poor, the production efficiency is low, and the long-term effective production cannot be well carried out.

To sum up, the utility model designs a notebook pivot support frame plastic frock.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 3, the following technical solutions are adopted in the present embodiment: the utility model provides a notebook pivot support frame plastic frock, including an upper fixing plate 1, the upper die base 2, guide pillar 3, the die holder 4, blanking plate 5, lower die fixing plate 6, slider 7, lower die mold insert 8, go up die mold insert 10 and slider guide pillar 11, upper die base 2 is fixed on upper fixing plate 1, guide pillar 3 is fixed on upper die base 2, be provided with die insert 10 and slider guide pillar 11 in the upper die base 2, die holder 4 is fixed on blanking plate 5, blanking plate 5 is fixed on lower die fixing plate 6, be provided with slider 7 and lower die insert 8 in the die holder 4, it carries out the pre-compaction when the compound die to set up the spring on the die insert 10, go up the mould and link through guide pillar 3 with the lower mould.

It should be noted that a specially-made upper mold insert 10 is arranged in the upper mold base 2 for pre-pressing to prevent the product from moving upwards during extrusion.

It is worth noting that the lower die holder 4 is provided with two sliding blocks 7 for extrusion, so as to achieve the shaping effect.

It is worth noting that the adjusting and positioning device 9 is arranged at the tail end of the sliding block 7, and the position of the sliding block can be freely adjusted, so that the product cannot fall down when being placed.

It is worth noting that a specially-made lower die insert 8 is arranged on the lower die base 4, the lower die insert is a rectangular insert, the rectangular insert is matched with the slide block 7, and the two slide blocks are matched up and down to perform extrusion, so that automatic blanking can be performed, material taking time is saved, and production efficiency is improved.

In addition, the height of the slider guide post 11 can be adjusted by padding a gasket with a corresponding size at the tail part, and the slider guide post is matched with the slider 7 on the lower die seat 4 to meet the shaping size requirement of the bottom opening of a product, and meanwhile, the width size of the product can also meet the requirement.

After the tool is shaped, the two sides of the bottom opening of the product are slightly stamped and almost have no deformation phenomenon, so that whether the product is subjected to a shaping process or not can be distinguished, the stamping after the shaping process can disappear in a rear-section polishing process, the performance of the product is not influenced completely, and the stamping only plays a role of temporary marking in the whole circulation process.

The shaping tool is assembled on a hydraulic press to operate, and a product is extruded through the cooperation of the slide block guide post 11 of the upper die holder and the slide block 7 of the lower die holder in the die assembly process so as to meet the requirement of shaping the size of the bottom opening of the product.

After the upper die and the lower die of the notebook computer rotating shaft support frame shaping tool are assembled, the product slotting part is extruded by the sliding block to realize the shaping function, and after the die is opened, the product slotting size is extruded to the required size, falls out of the lower die insert and falls out through the blanking plate slope slide way. The process does not influence the product performance, ensures the qualification rate of the product, can effectively improve the common deformation phenomenon of the powder injection molding process in the sintering process and the appearance crushing phenomenon caused in the shaping process, and well solves the problem that the size of the bottom opening of the product is unqualified due to the stress expansion factor after sintering.
