Description

Technical Field

[0001] This utility model relates to the field of ductile iron pipe production technology, specifically to a quick-change production date code component for ductile iron pipes. Background Technology

[0002] The production of ductile iron pipes and fittings requires the production date to be cast onto the fittings. Therefore, the outer mold of the mold used to produce the fittings must have embossed characters indicating the production date, and these characters must be changed according to the actual production date of the fittings.

[0003] Currently, the production date code made of rubber is widely used in the pipe fitting production process. When the production date needs to be changed, the original code must be destructively removed from the mold and a new code must be re-attached. This makes the rubber code a disposable consumable, which not only increases production costs, but also takes time to replace and clean, which is not conducive to production. At the same time, the removed rubber code cannot be reused, resulting in resource waste.

[0004] Therefore, there is an urgent need for a quick-change production date code component for ductile iron pipes to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a quick-change production date code component for ductile iron pipes, so as to solve the problem that the existing rubber code for the outer mold of ductile iron pipes needs to be improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change production date code component for ductile iron pipes, comprising a character block base and multiple character blocks. The bottom surface of the character block base is fixedly connected to the outer mold of the ductile iron pipe. A sliding groove is fixedly provided in the middle of the top surface of the character block base. At least one end of the sliding groove is open for inserting a character block. Both ends of the character block are respectively provided with sliders that match the side walls of the sliding groove and are slidably connected to the sliding groove. The top surface of each character block is fixedly provided with a protrusion for indicating the production date code. A blocking block is provided at the open end of the sliding groove, which is detachably fixedly connected to the character block base. The blocking block has two working states. In the first working state, it is fixedly connected to the character block base, and the side of the blocking block near the sliding groove is coplanar with the opening. In the second working state, the blocking block is separated from the character block base.

[0007] Preferably, the groove is a dovetail groove, the base of the character block has an isosceles trapezoidal cross-section, and the length of the lower base of the trapezoid matches the width of the groove bottom.

[0008] Preferably, the block holder has a screw hole at the connection point of the block, and the block and the block holder are connected by screws.

[0009] Preferably, there is only one block, and countersunk threaded through holes are respectively opened in the middle of the block seat and at the end away from the block, and the end of the slide groove away from the block is closed. The outer mold of the ductile iron pipe is provided with threaded holes that match the two countersunk threaded through holes. The block seat and the ductile iron pipe are fixedly connected by two countersunk screws.

[0010] Preferably, the block holder, the block, and the block are all made of metal.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This quick-change production date code component for ductile iron pipes has a simple structure and is easy to replace. Compared with the original rubber adhesive code, it eliminates the time-consuming processes of removal, cleaning, gluing, pasting, and drying, thus saving production time. It can be reused and does not lead to resource waste. In addition, it can be made of all-metal material, making it wear-resistant and durable. Attached Figure Description

[0021] like Figures 1 to 3As shown, a quick-change production date code assembly for ductile iron pipes includes a character block base 1 and multiple character blocks 2. The bottom surface of the character block base 1 is fixedly connected to the outer mold of the ductile iron pipe. A slide groove 11 is fixedly provided in the middle of the top surface of the character block base 1. At least one end of the slide groove 11 is open for inserting the character block 2. The two ends of the character block 2 are respectively provided with sliders that match the two side walls of the slide groove 11 and are slidably connected to the slide groove 11. The top surface of each character block 2 is fixedly provided with a protrusion for indicating the production date code.

[0022] A blocking block 3 is provided at the opening end of the slide groove 11, which is detachably and fixedly connected to the character block base 1. (See reference) Figure 2 In a preferred embodiment, the block holder 1 may have a screw hole 12 at the connection point of the block 3, and the block 3 and the block holder 1 are connected by screws.

[0023] The block 3 has two working states. In the first working state, it is fixedly connected to the character block seat 1, and the side of the block 3 near the slide groove 11 is coplanar with the opening. In the second working state, the block 3 is separated from the character block seat 1.

[0024] In a preferred embodiment, see [reference] Figures 4 to 6 The slide 11 is a dovetail groove, and the base of the character block 2 has an isosceles trapezoidal cross section, and the length of the lower base of the trapezoid matches the width of the bottom of the slide 11.

[0025] In a preferred embodiment, there is only one block 3. The middle part of the block seat 1 and the end away from the block 3 are respectively provided with countersunk threaded through holes, and the end of the slide groove 11 away from the block 3 is closed. The outer mold of the ductile iron pipe is provided with threaded holes that match the two countersunk threaded through holes. The block seat 1 and the ductile iron pipe are fixedly connected by two countersunk screws. Of course, a double block 3 can also be used, but when replacing the block 2, one of the block 3 does not need to be disassembled.

[0026] In a preferred embodiment, the character block holder 1, the character block 2, and the block block are all made of metal.

[0027] For reference, the production date displayed on the block 1 can be composed of numbers and letters. For example, it can be combined to form a production date of 4 numbers plus 1 letter, indicating the week of a certain year. Therefore, 5 blocks 2 are sufficient. From the perspective of convenient replacement, the block 3 for disassembly should be set at the end close to the block 2 indicating the week of the week. In most cases, only one block 2 needs to be replaced. When adjusting the week, 2 to 3 blocks 2 need to be replaced.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
