Problems solved by technology

[0003] However, the existing extruder casting molds still have the following defects: due to the relatively slow flow rate of the feed liquid in the extrusion casting process, on the one hand, in order to ensure the temperature of the feed liquid in the flow channel, and on the other hand, in order to prevent air entrainment in the flow channel, the existing The diameter of the runners is set larger, the ingate is thick, and the vertical squeeze casting is the center feed, so the cake formed in the ingate and the runner during casting is thicker and thicker, which makes it difficult to take out the cake. It is often necessary to manually dig out after mold opening, which is time-consuming and laborious, reducing production efficiency

Embodiment 1

[0025] As shown in the figure, a casting die for a vertical extrusion press includes a fixed die frame 1 and a movable die frame 2. A fixed die core 11 is provided at one end of the fixed die frame 1 facing the movable die frame 2. The fixed die frame 1 and the movable die frame 2 are provided with a fixed die core 11. The middle of the fixed mold core 11 is provided with a flow channel 12 vertically through it, the end of the fixed mold frame 1 facing away from the movable mold frame 2 is provided with a gate sleeve assembly 10, and the end of the movable mold frame 2 facing the fixed mold frame 1 is provided with a sprue sleeve assembly 10. The movable mold core 21, the movable mold core 21 and the fixed mold core 11 cooperate to form the cavity 3 of the casting after the mold is closed. The inner end of the runner 12 is the inner gate 13, which is connected to the cavity 3. The outer end of the runner 12 is connected to the sprue sleeve assembly 10, the outer end of the runn...

Embodiment 2

[0027]The present embodiment proposes a casting die for a vertical extrusion press, which further defines the structure of the hot-cutting mechanism 5 on the basis of the first embodiment. In this embodiment, the hot-cutting mechanism 5 includes a punching needle 51 and an insert sleeve 52 , the punching needle 51 is vertically arranged in the middle of the movable die frame 2 and the movable die core 21 , and the outer end of the punching needle 51 is connected to the hot-cutting driving mechanism 6 , the inner end of the punching needle 51 is flush with the surface of the movable die core 21, the punching needle 51 is arranged coaxially with the runner 12, the diameter of the punching needle 51 is slightly smaller than the diameter of the inner gate 13, when moving to the fixed die side The inner end of the punch 51 enters the gate 13 and fits with the inner wall of the runner 12 , the insert 52 is arranged between the movable die core 21 and the punch 51 , and the outer peri...

Embodiment 3

[0029] The present embodiment proposes a casting die for a vertical extrusion press, which further defines the structure of the hot cutting drive mechanism 6 on the basis of the first embodiment. In this embodiment, the eager drive mechanism 6 includes an oil cylinder 61 and a piston 62. The oil cylinder 61 is provided with a piston chamber 63 for the reciprocating motion of the piston 62. One end of the piston 62 is connected to the piston chamber 63, and the other end of the piston 62 is connected Connected to the outer end of the punching needle 51, the stroke range of the piston 62 is 40 to 50 mm.

Abstract

The invention discloses a casting mold for a vertical extrusion machine, which comprises a fixed mold frame and a movable mold frame. A fixed mold core is arranged in the fixed mold frame towards the end of the movable mold frame. The middle parts of the fixed mold frame and the fixed mold core are vertical Runners are arranged through it, a sprue sleeve assembly is provided in the feed port of the fixed mold frame, and a movable mold core is arranged in the end of the movable mold frame facing the fixed mold frame, and the movable mold core and the fixed mold core are matched after the mold is closed. The cavity of the casting is formed, the inner end of the runner is connected with the cavity, and the outer end of the runner is connected with the sprue sleeve assembly. An eager driving mechanism is arranged outside, and the eager driving mechanism is connected with the eager cutting mechanism, which drives the eager cutting mechanism to move to the fixed mold side to cut off the cake at the inner gate. The advantage is that it can be cut off in the mold after casting The cake at the ingate is cut off toward the fixed mold, and the cake is ejected, so that the cake is easily separated from the runner and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of extrusion casting moulds, in particular to a casting mould of a vertical extrusion machine. Background technique [0002] Squeeze casting is a common light-weight component forming technology in the industry. A certain amount of molten metal to be cast is injected into the cavity directly from the gate sleeve through the material cylinder, and is compressed by the movable mold and the fixed mold, so that the molten metal forms the casting according to the set structure in the cavity. , and demoulding after cooling to obtain casting products. [0003] However, the existing extrusion press casting mold still has the following defects: due to the relatively slow flow speed of the material liquid in the extrusion casting process, on the one hand, in order to ensure the temperature of the material liquid in the flow channel, and on the other hand, in order to prevent air entrainment in the flow channel, the existing T...
