Description

Technical Field

[0001] This application relates to the field of molds, and more specifically, to a swimming pool pump housing mold that avoids damaging threaded inserts. Background Technology

[0002] In the field of mold technology, the design and application of swimming pool pump housing molds play a crucial role in the production quality and efficiency of the pumps. With the development of the swimming pool equipment industry, the performance and quality requirements for swimming pool pumps are increasing, which in turn drives continuous optimization and innovation in pump housing molds.

[0003] In the traditional design of swimming pool pump housing molds, a copper nut needs to be placed below the inclined ejector of the mold. Since the threaded insert is placed on the front mold, when the mold is closed, the threaded insert pops out and is located on the back of the ejector. Therefore, when the conventional reset structure resets the inclined ejector during mold closing, it will damage the threaded insert, resulting in the swimming pool pump housing having mismatched threads and being unable to be assembled during use. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a swimming pool pump housing mold that avoids damaging the threaded inserts. It aims to improve the problem that the inclined ejector reset during mold closing will damage the threaded inserts, thereby causing the swimming pool pump housing to fail to assemble due to mismatched threads during use.

[0005] This application provides a swimming pool pump housing mold for avoiding damage to threaded inserts, including a front mold and a rear mold.

[0006] Each of the four corners of the rear mold is provided with a reset rod, and the top of each reset rod is slidably connected with an equal-height bolt. The top of each equal-height bolt contacts the front mold when the front mold and the rear mold are closed. Each equal-height bolt is fitted with a spring.

[0007] In one specific implementation, the reset rod has a sliding groove inside, and one end of the equal-height bolt is slidably disposed inside the sliding groove.

[0008] In one specific implementation, each of the equal-height bolts is fitted with spring washers at both ends of the spring, and one of the spring washers is mounted on the reset rod.

[0009] In one specific implementation, the front mold includes an A plate, on which a top groove is formed to mate with the equal-height bolt.

[0010] In one specific implementation, the top groove on plate A is a T-shaped groove, thereby enabling the movement of the equal-height bolt and the spring.

[0011] In one specific implementation, the rear mold includes a base and a B plate, one end of the reset rod is connected to the base, and the other end of the reset rod passes through the B plate and is connected to the equalizing bolt.

[0012] In one specific implementation, a relief groove is provided on plate B to cooperate with the equal-height bolt and the spring, and the top groove and the relief groove are interconnected.

[0013] In one specific implementation, the equal-height bolt is fixedly connected to a contact plate inside the sliding groove, and the contact plate slides in contact with the inner wall of the sliding groove.

[0014] Beneficial effects: 1. By using the cooperation of equal-height bolts and springs, the springs' own preload is used to press the inclined ejector first, and then the threaded insert is reset. This prevents the threaded insert from being damaged during the inclined ejector reset when the mold is closed, thus ensuring the accuracy of the threads on the swimming pool pump housing.

[0015] 2. By using the sliding connection between the equal-height bolt and the reset rod, the equal-height bolt can slide, thereby ensuring that the preload of the spring can be achieved. Attached Figure Description

[0019] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0020] Please see Figures 1-5 This application provides a swimming pool pump housing mold for avoiding damage to threaded inserts, including a front mold 1 and a rear mold 2.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Each of the four corners of the rear mold 2 is equipped with a reset rod 3, and the top of each reset rod 3 is slidably connected to an equal-height bolt 4. The top of each equal-height bolt 4 contacts the front mold 1 when the front mold 1 and the rear mold 2 are closed. Each equal-height bolt 4 is fitted with a spring 5. When the front mold 1 and the rear mold 2 are closed, the equal-height bolt 4 and the spring 5 work together to allow the spring 5 to pre-press first, achieving the reset of the inclined ejector. This leaves a 20mm gap between the inclined ejector and the threaded insert 7. Then, the threaded insert 7 is reset. Finally, the spring 5 is extended by the pressing force of the front mold 1 and the rear mold 2, allowing the equal-height bolt 4 to contact the front mold 1 after mold closure, thus achieving complete mold closure. The cooperation of the equal-height bolt 4 and the spring 5, with the pre-press of the spring 5 pre-pressing first, prevents damage to the threaded insert 7 during the reset of the inclined ejector, ensuring the accuracy of the threads on the swimming pool pump housing. The sliding connection between the equal-height bolt 4 and the reset rod 3 enables the equal-height bolt 4 to slide, thereby ensuring that the preload of the spring 5 can be achieved.

[0022] In this embodiment, the front mold 1 is provided with an injection port, and the rear mold 2 is provided with a mold core. The specific structure of the front mold 1 and the rear mold 2 and the injection principle are existing technologies and will not be described in detail here.

[0023] In this embodiment, a sliding groove 31 is provided inside the reset rod 3, and one end of the equalizing bolt 4 is slidably disposed inside the sliding groove 31. Each equalizing bolt 4 has a spring washer 6 fitted at both ends of the spring 5, and the two spring washers 6 respectively contact both ends of the spring 5. Under the action of the reset rod 3 and the bolt caps of the equalizing bolts 4, the spring 5 can extend or retract, and one spring washer 6 is supported on the reset rod 3. The front mold 1 includes an A plate, on which a top groove 11 is provided to cooperate with the equalizing bolt 4. The top groove 11 on the A plate is a T-shaped groove, thereby realizing the movement of the equalizing bolt 4 and the spring 5. When the front mold 1 and the rear mold 2 are closed, the equalizing bolt 4 and the spring 5 can slide inside the top groove 11, and after the mold is closed, the equalizing bolt 4 contacts the inner wall of the top groove 11, and under the action of the two spring washers 6, the spring 5 is compressed or extended when the equalizing bolt 4 is closed.

[0024] In its specific configuration, the rear mold 2 includes a base and a B-plate. One end of the reset rod 3 is connected to the base, and the other end of the reset rod 3 passes through the B-plate and is connected to the equalizing bolt 4. The B-plate has a clearance groove 21 that mates with the equalizing bolt 4 and the spring 5, and the top groove 11 is interconnected with the clearance groove 21. The connection between the clearance groove 21 and the top groove 11 allows for the extension and contraction of the spring 5 and the equalizing bolt 4.

[0025] Furthermore, the equal-height bolt 4 is fixedly connected to a contact plate 8 inside the sliding groove 31, and the contact plate 8 slides in contact with the inner wall of the sliding groove 31. The contact plate 8 makes the equal-height bolt 4 more stable when sliding, thereby increasing the stability of the front mold 1 and the rear mold 2 when the mold is closed.

[0026] The working principle of the swimming pool pump housing mold that avoids damaging the threaded inserts: When the front mold 1 and rear mold 2 are closed, the equalizing bolt 4 and spring 5 work together to ensure that the preload of spring 5 is used to preferentially press the mold during the closing process, first achieving the reset of the inclined ejector, leaving a 20mm gap between the inclined ejector and the threaded insert 7. Then, the threaded insert 7 is reset. Finally, the pressing force of the front mold 1 and rear mold 2 extends and contracts the spring 5, allowing the equalizing bolt 4 to contact the front mold 1 after mold closing, ultimately achieving complete mold closing. The cooperation of the equalizing bolt 4 and spring 5, utilizing the preload of spring 5 to preferentially press the mold, first achieves the reset of the inclined ejector, and then the reset of the threaded insert 7. This prevents damage to the threaded insert 7 during the reset of the inclined ejector, ensuring the accuracy of the threads on the swimming pool pump housing. The sliding connection between the equalizing bolt 4 and the reset rod 3 allows the equalizing bolt 4 to slide, thus ensuring that the preload of spring 5 can be achieved.
