[0002] To improve the filtration performance of pipe fittings, filter accessories are usually added inside the fittings. These filter accessories include horizontal pipe fittings and branch pipe fittings. During manufacturing, horizontal pipe fittings and branch pipe fittings are formed sequentially, which requires more time and results in lower product precision. Therefore, it is necessary to design a mold for pipe fitting filter accessories that can form horizontal pipe fittings and side branch pipe fittings in one step, thereby improving production efficiency and ensuring product precision. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mold for pipe fitting filter accessories, which can form horizontal pipe fittings and side branch pipe fittings in one step, thereby improving production efficiency and ensuring product precision.

[0004] To achieve the above objectives, this utility model provides a mold for a pipe fitting filter accessory, comprising an upper plate, an upper mold, a lower mold, a sprue sleeve, a transverse sliding insert, a side sliding insert, a sliding fixing plate, a shovel, a hydraulic cylinder, a base plate, mold feet, a pull pin, and pressure strips. The lower mold is mounted on the base plate using mold feet, and the upper mold covers the lower mold. The upper mold is mounted on the bottom of the upper plate. A transverse cavity and a side cavity are interconnected between the upper mold and the lower mold. The sprue sleeve passes through the upper plate and the upper mold and connects to the transverse cavity. A pull pin is provided in the lower mold below the sprue sleeve. Two transverse sliding inserts are arranged face-to-face in the transverse cavity. The outer ends of the transverse sliding inserts are connected to the sliding fixing plate. The piston rod of the hydraulic cylinder is connected to the sliding fixing plate. A side sliding insert is provided in the side cavity. The outer ends of the side sliding inserts are mounted on the front side of the lower mold using shovels. Pressure strips extending into the lower mold are provided on both sides of the side sliding inserts.

[0005] The base plate, mold feet and lower mold, upper mold and upper mounting plate, and slide fixing plate and transverse slide insert are fixed with screws.

[0006] The hydraulic cylinder is mounted on the hydraulic cylinder fixing plate, and the piston rod of the hydraulic cylinder passes through the pull plate and is connected to the sliding fixing plate.

[0007] An O-ring is provided between the positioning plate and the transverse positioning insert.

[0008] The gate sleeve is provided with a positioning ring.

[0009] The base plate is provided with a ejector plate, and a number of ejector pins are vertically arranged on the ejector plate.

[0010] The ejector plate and the lower mold are provided with a spring bend.

[0011] Compared with existing technologies, this invention designs a mold for pipe fitting filter accessories, enabling one-time molding of horizontal pipe fittings and side branch pipe fittings, thereby improving production efficiency and ensuring product precision. This invention has the advantages of simple structure, stability, and high efficiency. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] See Figures 1-4 This utility model relates to a mold for a pipe fitting filter accessory, comprising an upper platen, an upper mold, a lower mold, a sprue sleeve, a transverse sliding insert, a side sliding insert, a sliding fixing plate, a spatula, a hydraulic cylinder, a base plate, mold feet, a pull pin, and a pressure strip. The lower mold 11 is mounted on the base plate 22 using mold feet 19. The upper mold 9 covers the lower mold 11 and is mounted on the bottom of the upper platen 10. A transverse cavity and a side cavity are provided between the upper mold 9 and the lower mold 11. The sprue sleeve 5 passes through the upper platen 10 and the upper mold. After 9, it is connected to the transverse cavity. The lower mold 11 below the sprue sleeve 5 is provided with a pull pin 4. Two transverse sliding inserts 17 are provided face to face in the transverse cavity. The outer end of the transverse sliding insert 17 is connected to the sliding fixing plate 12. The piston rod of the oil cylinder 15 is connected to the sliding fixing plate 12. The side sliding insert 28 is provided in the side cavity. The outer end of the side sliding insert 28 is installed on the front side of the lower mold 11 by a spade 27. The two sides of the side sliding insert 28 are provided with pressure strips 30 extending into the lower mold 11.

[0018] For ease of fixing, screws 3 are used to fix the base plate 22, the mold foot 19 and the lower mold 11, the upper mold 9 and the upper mounting plate 10, and the sliding fixing plate 12 and the transverse sliding insert 17.

[0019] The hydraulic cylinder 15 is mounted on the hydraulic cylinder fixing plate 14. After the piston rod of the hydraulic cylinder 15 passes through the pull plate 13, it is connected to the sliding fixing plate 12.

[0020] An O-ring 8 is provided between the slide fixing plate 12 and the transverse slide insert 17 to ensure stable internal pressure in the transverse cavity during injection molding and improve the filling effect. A positioning ring 6 is provided on the outside of the sprue sleeve 5 to facilitate positioning of the sprue sleeve 5.

[0021] The base plate 22 is provided with an ejector plate 21, and several ejector pins 20 are vertically arranged on the ejector plate 21. The ejector pins 20 can help the product to be demolded.

[0022] A spring bend 18 is provided between the ejector plate 21 and the lower mold 11. The spring bend 18 assists the movement of the ejector plate 21 and provides structural support.

[0023] In operation, the material enters the transverse cavity and the side cavity from the sprue sleeve 5. Under the combined action of the transverse sliding insert 17 and the side sliding insert 28, a pipe filter accessory is formed. The hydraulic cylinder 15 provides sufficient pressure to the transverse sliding insert 17 to prevent displacement between the transverse sliding inserts 17 and between the transverse sliding insert 17 and the side sliding insert 28 during operation, thus ensuring product accuracy.

[0024] This invention designs a mold for pipe fitting filter accessories, enabling one-time molding of horizontal pipe fittings and side branch pipe fittings, improving production efficiency and ensuring product precision. This invention has the advantages of simple structure, stability, and high efficiency.
