A quick detachable injection head

Abstract

A quick assembling and disassembling injection head, comprising an injection head (1), an outer sleeve (2), an upper locking block (3), a lower locking block (4), a bottom plate (5), and a round clamp pin (6), wherein a clamp pin mounting slot (41) is formed in the lower locking block, the round clamp pin is provided in the clamp pin mounting slot of the lower locking block by means of a spring, and the round clamp pin is provided with a force which is always upward; the upper locking block is of an ''inverted T''-shaped structure, an upper surface of the upper locking block is fixedly connected to the injection head body, and a clamp pin groove (31) for clamping the round clamp pin is formed in the lower surface; an opening matched with the upper locking block is formed in an upper surface of the outer sleeve, and allows the upper locking block to pass through smoothly; and the lower locking block is provided on the bottom plate, and the outer sleeve is sleeved outside the lower locking block and is connected to the bottom plate. The injection head is rotatably fixed by means of the clamp pin, it is convenient to operate and disassemble, jamming would not occur after long-time use, and the injection head is prevented from rotating excessively by providing a limiting block (7).

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, in particular to a quick disassembly injection head. Background technique [0002] There is friction between the injection head and the mold, and the injection head needs to be replaced after long-term use. In the existing technology, the injection head of the mold is generally packaged with multiple barrels and the screw of the cylinder is threaded. If it is not disassembled for a long time, it may be stuck. , It is not easy to replace the injection head later, and the heavy injection head is easy to deviate from the barrel after being heated in the mold for a long time, resulting in wear of the barrel. Contents of the invention [0003] Aiming at the defects of the above prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses a quick disassembly injection head, including an injection head, a jacket, an upper lock block, a ...
