Technical Field
The utility model relates to a die-casting equipment technical field specifically is a die casting die runner cuts off structure.
Background
The die casting is a metal casting process, and is characterized in that the high pressure is applied to the molten metal by utilizing the inner cavity of the die, so that the die casting is suitable for producing light metal castings in a large scale, and the die casting is the most widely used process in various casting processes. The runner is used as a channel for the casting liquid to pass through during die-casting, after a product is formed, the runner and the product need to be cut off, the runner is cut off by a cutter generally at present, chips are easy to remain in the cutting mode, and the quality of the product can be influenced when the chips enter a cavity.
SUMMERY OF THE UTILITY MODEL
For solving prior art's not enough, this application provides a die casting die runner cutting structure, including movable mould, cover half and mould benevolence, mould benevolence sets up the movable mould with between the cover half, the cover half with set up the runner that supplies the pouring liquid to pass through on the mould benevolence, the runner includes horizontal runner and vertical runner, vertical runner top sets up and is used for carrying out the subassembly that cuts off that extrudees the runner after the shaping, it includes hydro-cylinder and extrusion round pin to cut off the subassembly, the hydro-cylinder sets up directly over the vertical runner, the extrusion round pin is connected to the output of hydro-cylinder.
Furthermore, the vertical runners comprise a plurality of vertical runners which are arranged at intervals along a straight line or arranged at intervals in the circumferential direction, and the multi-point feeding mode is adopted, so that the flow length can be reduced, the performance requirements on large-size die castings are met, and the consistency of products is improved.
Further, horizontal runner includes sprue and branch runner, branch runner includes many and one end is connected to vertical runner, the other end is connected the sprue.
Furthermore, the extrusion pin and the vertical runner are both of cylindrical structures, and the diameter of the circular section of the extrusion pin is larger than that of the circular section of the vertical runner.
Furthermore, a pin sleeve is arranged at the joint of the extrusion pin and the output end of the oil cylinder.
The application has the advantages that: the die casting die runner cutting structure who provides cuts off the product after the shaping through adopting extruded mode, and the structure is reliable, and mould action security is high, and crowded back of cutting does not have and remains and the piece, avoids getting into the die cavity and influences product quality, and provides product secondary pressure boost effect through the extrusion, increases the product feeding effect.

Labeled as: 10. the device comprises a movable die, 11, a fixed die, 12, a die core, 13, a sprue bush, 14, a cutting assembly, 141, an oil cylinder, 142, an extrusion pin, 143, a pin bush, 15, a runner, 151, a main runner, 152, a branch runner, 153, a vertical runner, 16 and a product.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the embodiment provides a die casting die runner cutting structure, including a movable die 10, a fixed die 11 and a die core 12, the die core 12 is disposed between the movable die 10 and the fixed die 11, an installation groove is formed in an end portion of the fixed die 11, a sprue bush 13 is disposed in the installation groove, a liquid outlet is disposed at a bottom of the sprue bush, a runner 15 through which a casting liquid passes is disposed on the fixed die 11 and the die core 12, the runner 15 includes a horizontal runner and a vertical runner 153, a cutting assembly 14 for performing extrusion cutting on the molded runner is disposed above the vertical runner, the cutting assembly 14 includes an oil cylinder 141 and an extrusion pin 142, the oil cylinder 141 is disposed directly above the vertical runner 153, and the extrusion pin 142 is connected to an output end of the oil cylinder 141.
Fig. 1 intercepts the local structure of the whole die-casting die, the number of the vertical runners 134 and the branch runners 133 is set according to the actual size of the product, the vertical runners adopted in this embodiment are arranged on the same straight line, and also can be arranged at the center of the fixed die according to different products, and other vertical runners can be circumferentially arranged along the vertical runners.
Specifically, pin sleeves 143 are provided at the connection positions of the squeeze pins 142 and the output ends of the oil cylinders 141, and the number of the oil cylinders 141 is set according to the number of the vertical flow passages 134.
Specifically, the horizontal runners include a main runner 151 and branch runners 152, the number of the branch runners 152 corresponds to the number of the vertical runners 153, one end of each branch runner is connected to the vertical runner, the other end of each branch runner is connected to the main runner, and the main runner is connected to a liquid outlet at the bottom of the sprue bush 13.
Preferably, the squeeze pin 142 and the vertical flow passage 153 are cylindrical, and the diameter of the circular cross section of the squeeze pin is larger than that of the vertical flow passage, and only needs to be slightly larger.
The working principle is as follows: the molten metal flows out from a liquid outlet at the bottom of the sprue bush 13, and flows out from the main runner 151 to the branch runners 152 in sequence, and then flows into the cavity through each vertical runner 153, after the product is preliminarily formed, the oil cylinder 141 is started to drive the extrusion pin 143 to cut off the upper end of the vertical runner, and then the mould is opened to take out the product 16 and the horizontal runner.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
