Detailed Description

Referring to fig. 1 to 14, a blade forming mold in the drawings includes an upper mold 1, a lower mold 2, a petiole forming mold 3, and a petiole forming module 4; the molding of the integral blade 5 can be completed by the four molds. The blade 5 mainly comprises a blade handle 51, a blade body 52 and a blade tail, wherein the blade body 52 is positioned between the blade handle 51 and the blade tail.

The upper die 1 and the lower die 2 are integrally spliced into a conventional square die structure, wherein a first petiole forming die placing groove 11, a blade body protruding part 12 and a first blade tail forming die placing groove 13 are formed in the joint position of the upper die 1 and the lower die 2; wherein the first petiole forming die placing groove 11 is used for placing the upper half of the petiole forming die 3. The blade body protrusion 12 is used to match with the blade body groove 22 of the lower die 2 to form a blade body forming cavity, so that the blade body forming cavity corresponding to the shape of the blade body 52 is formed inside the upper die 1 and the lower die 2 except for the blade stalk 51 and the blade tail. The first blade tail forming die placing groove 13 is used for placing the upper half part of the blade tail forming die.

A second blade handle forming die placing groove 21, a blade body groove portion 22 and a second blade tail forming die placing groove 23 are sequentially matched with the corresponding matching position of the lower die 2; the second petiole forming die placing groove 21 is used for placing the lower half part of the petiole forming die 3; the second blade tail forming die placing groove 23 is used for placing the lower body part of the blade tail forming die. Wherein, the blade body convex part 12 and the blade body concave part 22 are fit to correspond to the shape of the blade body 52 of the blade 5.

Through the design of the upper die 1 and the lower die 2, the blade handle forming die 3 and the blade tail forming die set 4 can be fixed to simultaneously complete the forming of the blade 5. In practical application, the petiole forming die 3 and the petiole forming die group 4 are respectively arranged at the left side edge position and the right side edge position of the joint of the upper die 1 and the lower die 2. The top of the upper die 1 is correspondingly provided with an injection port which is directly communicated with the joint of the upper die 1 and the lower die 2 so as to form the blade 5.

The petiole forming die 3 is provided with a petiole forming cavity 31 mainly for forming a part of the petiole 51 in front of the blade 5.

The blade tail forming module 4 is internally provided with a blade tail forming cavity 43; mainly for forming the tail portion of the blade 5. The blade tail forming module 4 comprises a blade tail top die 41 and a blade tail bottom die 42; the shape of the joint of the leaf tail top die 41 and the leaf tail bottom die 42 corresponds to the shape of the leaf tail; the blade tail bottom mold 42 has two first blade tail grooves 421, i.e., front and rear first blade tail grooves 421, and the blade tail top mold 41 has two second blade tail grooves 411 corresponding to the first blade tail grooves 421. The bottom of the blade tail top mold 41 has a first curved surface 441, the top of the blade tail bottom mold 42 has a second curved surface 442, and the shape of the combination of the first curved surface 441 and the second curved surface 442 corresponds to the shape of the blade tail. Therefore, when the blade 5 is made into a short blade 5, the plastic of the injection molding opening only needs to be injected to the first blade tail groove 421 in the front, and a strip-shaped stopper can be added for placing the plastic injected to the first blade tail groove 421 in the back; when the long blade 5 needs to be manufactured, the plastic of the injection port is injected to the position of the first rear blade tail groove 421, so that the lengthened section 531 is formed; by adopting the configuration, the blade 5 with two length specifications can be manufactured by one die.
