Description

Technical Field

[0001] The utility model relates to the technical field of plastic car lamp molds, and particularly relates to a water connection structure for facilitating the quick disassembly and assembly of ejector blocks. Background Art

[0002] The mold ejector block, also known as the angled pin or angled lifter, is a common term in the mold industry in the Pearl River Delta region mainly composed of Hong Kong-funded mold factories. It is a mechanism used in mold design to form internal undercuts of products and is suitable for relatively simple undercut situations. It is often used in plastic car lamp molds.

[0003] When a plastic car lamp mold is in production, cooling water is required to quickly cool down the mold, and cooling water is also needed in the set ejector block for quick cooling. However, in the past, the water connection structure of the ejector block usually connected the water pipe to an extended water pipe, and the extended water pipe was then connected to the ejector rod. Each time the ejector block needed to be replaced, the extended water pipe had to be removed before the ejector block (angled lifter) could be removed, as Figure 1 shown, resulting in very inconvenient replacement of the ejector block. For this reason, we propose a water connection structure for facilitating the quick disassembly and assembly of the ejector block to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water connection structure for facilitating the quick disassembly and assembly of the ejector block to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water connection structure for facilitating the quick disassembly and assembly of the ejector block, comprising:

[0006] An ejector plate, two insertion slots are opened on the ejector plate, two ejector rods are movably inserted into the two insertion slots respectively, a connecting pipe is fixedly installed at the top ends of the two ejector rods, a same ejector block is fixedly installed at the top ends of the two ejector rods, the connecting pipe is arranged inside the ejector block, two installation slots are opened on the front side wall of the ejector plate, the two installation slots are respectively communicated with the two insertion slots, extended water pipes are hermetically installed in the two installation slots, an annular semi-circular groove is opened at the bottom end position of the ejector rod, and a water inlet hole is opened on the annular semi-circular groove, and the water inlet hole is communicated with the inner cavity of the ejector rod.

[0007] Preferably, a water inlet pipe is fixedly installed at the outer end of one of the extended water pipes, and a water outlet pipe is fixedly installed at the outer end of the other extended water pipe.

[0008] Preferably, two installation holes are opened on the bottom wall of the ejector plate, the two installation holes are respectively communicated with the two insertion slots, fastening bolts are arranged in the installation holes, and the fastening bolts are threadedly connected to the bottom ends of the ejector rods.

[0009] Preferably, sealing ring grooves are formed in the bottom wall of the ejector rod and the surface above the annular semi-circular groove, and a waterproof sealing ring is fixedly installed in the sealing ring groove.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model changes the traditional connection method of connecting the ejector rod to the water pipe through an extended water pipe to a connection method where the water pipe is connected to the ejector pin plate through an extended water pipe. The ejector rod is movably inserted into the insertion groove of the ejector pin plate and sealed by the provided waterproof sealing ring. The bottom end of the ejector rod is fixedly connected to the insertion groove of the ejector pin plate by a fastening bolt provided in a threaded manner. When it is necessary to disassemble and assemble the top block at the top end of the ejector rod, it is only necessary to remove the fastening bolt and pull out the ejector rod from the insertion groove, making the ejector rod easy to disassemble, thereby improving the convenience of disassembling and assembling the top block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a water transportation connection structure for facilitating the quick disassembly and assembly of the top block, including:

[0019] The ejector plate 1 is provided with two insertion slots 2. Two ejector rods 3 are movably inserted into the two insertion slots 2 respectively. A connecting pipe 4 is fixedly installed at the top ends of the two ejector rods 3. A same ejector block 5 is fixedly installed at the top ends of the two ejector rods 3. The connecting pipe 4 is arranged inside the ejector block 5. Two installation slots 6 are formed on the front side wall of the ejector plate 1. The two installation slots 6 are respectively communicated with the two insertion slots 2. Two extension water pipes 7 are hermetically installed in the two installation slots 6 respectively. An annular semi-circular groove 10 is formed at the bottom end position of the ejector rod 3. A water inlet hole 11 is formed in the annular semi-circular groove 10. The water inlet hole 11 is communicated with the inner cavity of the ejector rod 3.

[0020] The outer end of one of the extension water pipes 7 is fixedly installed with a water inlet pipe 8. The outer end of the other extension water pipe 7 is fixedly installed with a water outlet pipe 9. The water inlet pipe 8 facilitates the cooling water to enter the inner cavity of the ejector rod 3 and flow into the water outlet pipe 9 through the connecting pipe 4 for discharge.

[0021] Two installation holes 12 are formed on the bottom wall of the ejector plate 1. The two installation holes 12 are respectively communicated with the two insertion slots 2. A fastening bolt 13 is arranged in the installation hole 12. The fastening bolt 13 is threadedly connected to the bottom end of the ejector rod 3. By providing the fastening bolt 13, it is convenient to fixedly install the ejector rod 3 in the insertion slot 2. When it is necessary to remove the ejector rod 3, only the fastening bolt 13 needs to be removed and the ejector rod 3 can be pulled out from the insertion slot 2, improving the convenience of disassembly and assembly of the ejector rod 3.

[0022] Sealing ring grooves 14 are formed on the bottom wall of the ejector rod 3 and the surface above the annular semi-circular groove 10. A waterproof sealing ring 15 is fixedly installed in the sealing ring grooves 14. The waterproof sealing ring 15 can improve the sealing performance when the ejector rod 3 is inserted into the insertion slot 2 and avoid water leakage.

[0023] Working principle: The utility model changes the connection mode of the traditional ejector rod with the water pipe through the extension water pipe 7 to the connection mode of the water pipe with the ejector plate 1 through the extension water pipe 7. The ejector rod 3 is movably inserted into the insertion slot 2 of the ejector plate 1 and is sealed by the provided waterproof sealing ring 15. The bottom end of the ejector rod 3 is threadedly fixed to the connection of the insertion slot 2 of the ejector plate 1 by the provided fastening bolt 13. When it is necessary to disassemble and assemble the ejector block 5 at the top end of the ejector rod 3, only the fastening bolt 13 needs to be removed and the ejector rod 3 can be pulled out from the insertion slot 2, making the ejector rod 3 easy to disassemble, thereby improving the convenience of disassembly and assembly of the ejector block.
