[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 A television mold with a replaceable ejector block comprises a mold body 1 with a cavity therein, an ejector hole penetrating to the internal cavity is opened on the outer side of the mold body 1, and an ejector mechanism 2 for blocking the ejector hole is arranged in the ejector hole. The ejector mechanism 2 comprises an ejector block 210 arranged in the ejector hole, and the ejector block 210 is detachably connected to an ejector rod 220 for pushing the ejector block 210 to move toward the cavity. The ejector block 210 moving into the cavity ejects the molded workpiece out of the mold, and when the contact surface between the ejector block 210 and the workpiece in the mold is worn due to extensive use, the ejector block 210 can be quickly replaced with a new one.

[0017] The top block 210 also includes a locking pin 230. The outer side of the top block 210 is provided with a receiving groove for receiving the ejection rod 220. The receiving groove is provided with a hole that penetrates the side of the top block 210. The locking pin 230 is slidably connected in the hole. The ejection rod 220 is provided with a hole for receiving the locking pin 230. The top block 210 and the ejection rod 220 are fixed together by the locking pin 230. The top block 210 and the ejection rod 220 can be quickly disassembled and separated by removing the locking pin 230, thereby realizing the quick disassembly and assembly of the top block 210 and the ejection rod 220.

[0018] One end of the ejector rod 220 is provided with a connecting portion 221 for inserting into the receiving groove, and the cross-sectional area of ​​the connecting portion 221 is smaller than the cross-sectional area of ​​the ejector rod 220. That is, the connecting portion 221 is inserted into the receiving groove and fixed inside the ejector block 210, and the body of the ejector rod 220 presses against the outer side of the ejector block 210, so that the thrust exerted by the ejector rod 220 on the ejector block 210 can be evenly distributed, preventing the thrust of the ejector rod 220 from being too concentrated to cause damage to the ejector block 210.

[0019] One side of the ejection hole is an inclined surface, and the opening area of ​​the ejection hole on the side of the cavity is larger than the opening area of ​​the ejection hole on the outer side of the mold body 1. This ensures that the ejection block 210 will not separate from the mold body 1 when moving away from the cavity in the mold body 1.

[0020] One end of the ejector rod 220 away from the ejector block 210 is fixedly connected to the support seat 3, and the support surface of the support seat 3 is arranged perpendicularly to the length direction of the ejector rod 220. The support seat 3 is used to increase the pressure of the ejector rod 220, specifically the pressure generated by the reaction force generated by the ejector rod 220 pushing the ejector block 210. The support surface of the support seat 3 is arranged perpendicularly to the length extension direction of the ejector rod 220, which is a conventional setting in the art and is used to prevent the ejector rod 220 from bending under force.

[0021] A threaded hole is formed on the end surface of the ejector rod 220 away from the ejector block 210 , and a threaded hole corresponding to the threaded hole of the ejector rod 220 is formed on the support seat 3 . The ejector rod 220 and the support seat 3 are connected by bolts.

[0022] Working principle: Connect the ejector rod 220 to the support seat 3 by bolts, place the ejection hole of the mold body 1 at the front end of the connecting part 221, move the mold body 1 so that the connecting part 221 extends into the cavity through the ejection hole, connect and fix the ejector block 210 to the connecting part 221, and then move the mold body 1 to move the ejector block 210 away from the cavity until the ejector block 210 is squeezed by the inclined surface of the ejection hole and cannot move. When in use, after the workpiece in the mold body 1 is formed, move the mold body 1 toward the direction of the support seat 3, and the ejector rod 220 will push the ejector block 210 toward the cavity in the mold body 1 to eject the workpiece in the cavity out of the cavity.

[0023] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, and may be located in one place or distributed over multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
