Detailed Description
The following description will be made in conjunction with the accompanying drawings.
As a specific embodiment, the mobile phone bottom case ejection mold according to an embodiment of the present invention includes an ejection assembly 2 and a forming mold 1 having a mold core surface 11. The core surface 11 is used to form a cavity in cooperation with other parts of the forming mold 1, and after fluid plastic or the like is injected into the cavity, the workpiece W is formed after the fluid plastic is cooled.
The ejection assembly 2 comprises a product thimble 21 in linear sliding connection with the forming die 1, and one end of the product thimble 21 is exposed out of the die core surface 11. The product thimble 21 is inserted into a hole formed in the forming die 1 so as to realize a linear sliding connection with the forming die 1. One end of the product thimble 21 is exposed from the mold core surface 11 and is approximately flush with the mold core surface 11. The product thimble 21 moves linearly, and one end of the product thimble 21 abuts against the workpiece W, so that the workpiece W is demolded.
The molding die 1 includes a movable element 12 having a linear power. The movable element 12 is provided with linear power by a linear power element (not shown) such as a hydraulic cylinder or an air cylinder.
The ejection assembly 2 further comprises an accelerator 22 and a rotary member 23 articulated to the movable member 12. The rotary member 23 is provided with a hinge shaft 239, the movable member 12 is provided with a hinge seat 121, and the hinge shaft 239 is embedded in the hinge seat 121, so that the rotary member 23 is hinged to the movable member 12.
The forming die 1 is provided with a stopper surface 13. In a specific embodiment, the movable member 12 is located in a cavity (not shown) of the forming mold 1, and the top end surface of the cavity of the forming mold 1 is a stopper surface 13.
The two ends of the rotating member 23 are a product ejecting end 231 and an accelerating end 232, respectively, and the axial line of the rotating member 23 hinged to the movable member 12 is located between the product ejecting end 231 and the accelerating end 232.
The product ejecting end 231 abuts against the movable element 12 (i.e. the positioning surface 235 abuts against the movable element 12), and the product ejecting pin 21 abuts against the product ejecting end 231, so that the movable element 12 can drive the product ejecting pin 21 to move.
The accelerating element 22 is located between the accelerating end 232 and the limiting surface 13.
The ejection assembly 2 further comprises a reset piece 211, and the reset piece 211 is respectively connected with the product thimble 21 and the movable piece 12, so that the product thimble 21 has a tendency to be reset close to the rotating piece 23.
As a specific embodiment, the reset element 211 is a spring and is sleeved on the product thimble 21, the movable element 12 includes a fixed mounting element 122, the mounting element 122 is fixedly provided with a reset mounting cover 212, and two ends of the reset element 211 respectively abut against the reset mounting cover 212 and the product thimble 21, so that the product thimble 21 tends to be reset close to the rotating element 23. The movable piece 12 and the ejection assembly 2 are assembled into a whole, so that the assembly of the mold is facilitated.
The working principle is that when the workpiece W needs to be demolded, the movable part 12 moves to move the product thimble 21 until the two ends of the accelerating part 22 respectively abut against the accelerating end 232 and the limiting surface 13, so that the rotating part 23 rotates, and the product thimble 21 has a faster moving speed than the movable part 12, so that the workpiece W is accelerated and ejected by the product thimble 21 for a certain distance, and the workpiece W is not easily clamped and is relatively smooth in production.
In one embodiment, the movable member 12 includes a fixed mounting member 122, and the accelerating member 22 is slidably coupled to the mounting member 122 in a linear direction and contacts the accelerating end 232. The movable piece 12 and the ejection assembly 2 are assembled into a whole, so that the assembly of the mold is facilitated.
As a specific embodiment, the accelerator 22 is fixedly disposed on the stopper surface 13.
The ejection assembly 2 further comprises a locking member 24 shorter than the accelerating member 22, the rotating member 23 comprises a fixed portion 234, the locking member 24 is disposed between the fixed portion 234 and the limiting surface 13, and the locking member 24 substantially passes through the hinge axis line of the rotating member 23 and the movable member 12. The movable piece 12 moves to make the product thimble 21 move until the two ends of the accelerating piece 22 respectively support against the accelerating end 232 and the limiting surface 13, so that the rotating piece 23 rotates; until the two ends of the locking piece 24 are respectively abutted against the fixing part 234 and the limiting surface 13, the locking piece 24 applies a force pointing to the hinge axis of the rotating piece 23 and the movable piece 12 to the fixing part 234, so that the rotating piece 23 stops rotating, that is, the rotation of the rotating piece 23 can be locked, and the position of the workpiece W after demoulding is relatively stable.
In one embodiment, the movable member 12 includes a fixed mounting member 122, and the locking member 24 is linearly slidably coupled to the mounting member 122 and contacts the accelerator end 232. The movable piece 12 and the ejection assembly 2 are assembled into a whole, so that the assembly of the mold is facilitated.
The edge of the cross section of the fixing portion 234 that can abut against the locking member 24 is a circular arc. It is possible to ensure that the rotation effect of the locking rotator 23 is relatively stable.
