Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing equipment, and particularly relates to a forming device for a three-way elbow. Background Technique

[0002] A three-way elbow refers to a fitting used on water pipes and is very common in our daily life. The main materials are stainless steel and plastic. In order to improve the tightness of the three-way elbow, most three-way elbows are injection molded using an integrated forming device.

[0003] The existing integrated forming device has the following deficiencies in the specific use process:

[0004] 1. The upper and lower molds are fixedly connected by bolts, the operation is cumbersome, and the connection efficiency is low;

[0005] 2. Demoulding requires manual knocking and removing of the three-way elbow, and there is a certain probability of damage.

[0006] For example, an integrated forming device for processing a three-way elbow with a publication number of CN219236043U includes a heat dissipation box. A baffle is fixedly installed on the heat dissipation box. A bottom mold and a first electric push rod are fixedly installed on the baffle. And a cover mold matching with the bottom mold is installed on the baffle through a sliding mechanism. A plugging plate is fixedly installed on the first electric push rod. A first steel column is fixedly installed on the plugging plate. A second electric push rod is fixedly installed on the heat dissipation box. A second steel column is fixedly installed on the second electric push rod. The advantages are as follows: There is no need to manually knock the three-way elbow off the steel column, which can effectively protect the formed three-way elbow. At the same time, the clamping and fixing between the hook and the clamping block are used to replace the original bolt fixed connection method, making the fixation between the cover mold and the bottom mold more convenient and the installation and disassembly efficiency higher.

[0007] The above technical solution still has problems of low disassembly and assembly efficiency of the mold combination and inconvenient demoulding after the three-way is formed in practical applications.

[0008] Therefore, it is very necessary to invent a forming device for a three-way elbow to solve the above problems. Content of the Utility Model

At one end of the two inserting rods 7 away from each other, a positioning sleeve 17 is sleeved, and the positioning sleeve 17 is fixedly arranged inside the support frame 1. The positioning sleeve 17 is used to limit the movement track of the inserting rod 7;

[0026] More specifically, on both sides of the movable seat 3, extending arms 10 are movably arranged through pin shafts, and the extending arms 10 are movably connected to the top ends of the movable arms 4 through pin shafts. The movable seat 3 can drive the movable arms 4 to move through the extending arms 10. Since the movable seat 3 and the extending arms 10 are connected through pin shafts, the movement among the three will not interfere with each other;

[0027] Moreover, outer molds 11 are arranged on both sides of the core mold 8. A connecting ear 12 is fixedly arranged at the top of the outer side wall of the outer mold 11. A pin rod 13 is penetratingly arranged at the top of the connecting ear 12, and the pin rod 13 is fixedly arranged inside the support frame 1;

[0028] Furthermore, a transmission arm 14 is fixedly arranged at the bottom end of the outer side wall of the outer mold 11.

The melted raw material is injected between the outer mold 11 and the core mold 8 through the feed pipe 18 and is formed between the outer mold 11 and the core mold 8. After the tee product is formed, the electric push rod 2 drives the movable seat 3 to move upward. The movable seat 3 drives the top end of the movable arm 4 to move through the extension arm 10, so that the movable arm 4 rotates around the pin shaft at its bottom end. At this time, the movable arm 4 squeezes the sliding rod 6 through the chute in the middle thereof, and the sliding rod 6 drives the insertion rod 7 to move, so that the insertion rod 7 drives the core mold 8 to move. At this time, the three core molds 8 are mutually separated. During this process, the movable seat 3 drives the driving arm 15 to move through the connecting arm 16, and the driving arm 15 drives the outer mold 11 to move through the transmission arm 14, so that the outer mold 11 drives the connecting ear 12 to rotate around the pin rod 13. At this time, the two outer molds 11 open, and the three core molds 8 are mutually separated. At this time, the formed tee product is separated from the core mold 8 and the outer mold 11 and freely falls to complete the automatic demolding of the product.
