SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect and provide a keep away metal terminals of metal fillings and bury forming die, effectively solve and bury the shaping metal fillings problem, promote the product quality.
The technical scheme for realizing the purpose is as follows:
a metal terminal embedding forming die for avoiding metal chips is inserted into a metal terminal and comprises a first terminal groove insert, a second terminal groove insert and a terminal stop block, wherein,
a plurality of terminal grooves are formed on the front vertical surface of the first terminal groove insert along the vertical direction,
a placing groove for placing the terminal stop block is formed in the middle of the front vertical surface of the first terminal groove insert along the horizontal direction;
two first chip-avoiding grooves are formed at two ends of the bottom of each terminal groove;
the second terminal slot insert and the first terminal slot insert are spliced front and back;
and the right positions of the rear vertical surface of the second terminal groove insert and the terminal grooves are provided with two second chip-avoiding grooves which are right opposite to the corresponding two first chip-avoiding grooves one by one along the vertical direction.
Preferably, an upper portion of each terminal groove above the terminal block, an upper portion of the corresponding first chip groove, and an upper portion of the corresponding second chip groove are combined to form each terminal fixing groove hole; the metal terminals are inserted into the terminal fixing groove holes.
Preferably, the root chamfer of the first chip-avoiding groove and the second chip-avoiding groove is less than 0.02mm,
the in-groove roughness of the terminal groove, the first chip-avoiding groove and the second chip-avoiding groove is less than Ra0.1.
Preferably, the depth of the first chip-avoiding groove and the second chip-avoiding groove is smaller than the overflow limit of the plastic material;
the metal terminals have a contact width greater than 2/3 of the metal terminal width.
The utility model has the advantages that: the utility model discloses a chip groove on the chip groove of avoiding designing special construction effectively avoids the metal fillings on the metal terminal and the contact of injection mould terminal groove to it is bad to have avoided the metal fillings on the plastic product, compares with traditional terminal fixed slot, can effectively improve the injection moulding product yield, produces because of the very big reduction metal fillings of production process, so great reduction the frequency of repairing the mould, improvement production efficiency.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 to 5, the metal terminal for avoiding the metal chips of the present invention is embedded in a molding die and inserted into a metal terminal 100, which includes a first terminal groove insert 1, a second terminal groove insert 2 and a terminal stopper 3.
The front vertical surface of the first terminal groove insert 1 is provided with a plurality of terminal grooves 11 along the vertical direction, and the middle of the front vertical surface of the first terminal groove insert 1 is provided with a placing groove 12 for placing the terminal block 3 along the horizontal direction.
Two first chip-avoiding grooves 4 are formed at two ends of the bottom of each terminal groove 11; the second terminal slot insert 2 and the first terminal slot insert 1 are spliced front and back.
The right positions of the rear vertical surface of the second terminal groove insert 2 and the terminal grooves 11 are provided with two second chip-avoiding grooves 5 which are right opposite to the corresponding two first chip-avoiding grooves 4 one by one in the vertical direction.
The upper part of each terminal groove 11 above the terminal block 3, the upper part of the corresponding first chip-avoiding groove 4 and the upper part of the corresponding second chip-avoiding groove 5 are combined to form each terminal fixing groove hole; the metal terminals 100 are inserted into the terminal fixing groove holes.
Root clearance angles of the first chip grooves 4 and the second chip grooves 5 are less than 0.02mm, and the in-groove roughness of the terminal grooves 11, the first chip grooves 4 and the second chip grooves 5 is less than Ra0.1. The depth of the first chip-avoiding groove 4 and the second chip-avoiding groove 5 is less than the overflow limit of the plastic material; the contact width L2 of the metal terminal 100 is greater than 2/3 of the width L1 of the metal terminal 100.
The material used for the first terminal groove insert 1 and the second terminal groove insert 2 is SKD61 tool steel. The depth D of the first chip flutes 4 and the second chip flutes 5 is determined by the plastic material and the injection pressure.
In summary, the terminal block 3 divides the upper and lower portions of the terminal groove 11 into a chip-avoiding region and a chip-storing region, and a very small portion of metal chips adhered to the metal terminal 100 will slide into the chip-storing region below the terminal block 3 along the first chip-avoiding groove 4 and the second chip-avoiding groove 5 during the process of inserting into the terminal-fixing groove hole. The problem of embedding molding metal chips can be effectively solved, the product quality is improved, the die repairing frequency is reduced, and the production efficiency is improved.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
