Description

Technical Field

[0001] This utility model belongs to the field of forming mold technology, specifically relating to an automatic oil injection system for forming molds of high specific gravity products. Background Technology

[0002] During the metal injection molding process, the counterweight product shrinks after sintering, and the inner frame becomes concave. The shaping process requires inserts to be stamped into the inner frame of the product to meet the dimensional requirements. During the shaping process, friction occurs between the product and the inserts, which causes burrs to form on the product, making it impossible to meet the product's appearance requirements. Furthermore, due to frequent friction, the inserts will wear down, increasing the cost of accessories. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0018] Please see Figure 1-4 An automatic oil injection system for high-density product shaping molds includes an oil inlet pipe 1, an oil storage tank 2, an oil discharge channel 4, an oil discharge pipe 5, and an oil storage tank 6.

[0019] Specifically, the oil inlet pipeline 1 includes an oil inlet connecting hose 101 and an oil inlet stainless steel pipe 102. The oil inlet stainless steel pipe 102 is installed inside the upper mold of the mold. The outer end of the oil inlet connecting hose 101 is connected to the outlet of the oil storage tank 2, and its inner end is connected to the outer end of the oil inlet stainless steel pipe 102. In this embodiment, a forming mold is provided with multiple forming stations. The oil inlet stainless steel pipe 102 is a bent pipe structure. Each forming station is provided with a corresponding branch pipe. The pipe opening of the branch pipe is set directly above the stamping forming insert 3, so as to guide the oil flowing out of the oil storage tank 2 to the forming position.

[0020] Specifically, the oil drain channel 4 is set on the lower mold base plate of the forming mold, including the oil guide groove 401, the oil drain groove 402 and the oil drain hole 403.

[0021] The lower die base plate is provided with a recessed groove structure, and multiple oil guide grooves 401 are formed on the bottom surface of the recess, which are strip-shaped groove structures with one side opening; oil drain grooves 402 are formed on the bottom surface of the recess and are set along the four sides of the recess. One side of the oil guide groove 401 is located below the stamping and forming insert 3, and the other side is an open side that communicates with the oil drain groove 402. An oil drain hole 403 is formed on one side wall of the recess and has a threaded structure for connection.

[0022] Specifically, the oil drain line 5 includes an oil drain connecting hose 501 and a stainless steel connector 502. The outer end of the stainless steel connector 502 is connected to the oil storage tank 6 through the oil drain connecting hose 501. The inner end of the stainless steel connector 502 is provided with a threaded section and is fixedly assembled in the oil drain hole 403.

[0023] Specifically, the mold is equipped with insert 7, insert 8, and insert 3 11 to limit the product 9. Insert 7, insert 8, and stamping forming insert 3 are respectively limited in the mold by fixing seat 10, fixing seat 2 11, and fixing seat 3 12.
