Description

Technical Field

[0001] This utility model relates to a quick connector forming mold with a spring block structure. Background Technology

[0002] like Figure 1 and Figure 2 As shown, there is a type of water chamber product 4 with a sloping bottom surface. The product has a quick connector on one side. The existing mold uses vertical inserts 2 and inserts 3 to directly demold the quick connector. Since the quick connector is formed on the vertical inserts 2 and inserts 3, the injection molding is completed in one mold opening. However, since the quick connector is not parallel to the bottom surface (there is a 92-degree angle), the quick connector is tilted after injection molding, which does not meet the product requirements. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a quick connector forming mold with a spring block structure, which ensures that the quick connector is perpendicular to the bottom surface of the product, meeting product requirements.

[0004] This utility model adopts the following technical solution: a quick connector molding mold with a spring block structure, including a panel, a hot runner plate and an A plate, with a front mold core disposed inside the A plate. The product with the quick connector is disposed inside the front mold core. A spring block and a spring block insert are disposed above the quick connector. The spring block and the spring block insert are inclined relative to the horizontal plane. The spring block is driven to move by a spring block seat disposed inside the hot runner plate. When the mold is opened, the spring block and the spring block insert are driven to open the mold by the spring block seat. The A plate and the front mold core do not move. After the spring block and the spring block insert open the mold, the A plate and the front mold core open the mold again.

[0005] Preferably, a pressure block assembly is provided between the spring block seat and the spring block.

[0006] Preferably, the pressure block assembly includes a first pressure block and a second pressure block, wherein a needle groove for accommodating the insert pin of the spring block is formed between the first pressure block and the spring block.

[0007] Preferably, the top of the first pressure block forms a cavity to accommodate the end of the spring insert pin.

[0008] Preferably, a transverse groove is formed on the upper part of the second pressure block, and a locking block is formed at the bottom of the spring block seat to match the groove.

[0009] Preferably, the top of the spring block seat is positioned on the hot runner plate by fastening screws.

[0010] This invention adds a front mold spring block and a front insert pin that are inclined to the horizontal plane at the quick connector of the product. The spring block is molded first and then the whole mold is molded, which solves the problem of the quick connector tilting after injection molding and meets the product requirements.

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] like Figure 3 and Figure 4 The quick connector molding die with a spring block structure shown includes a panel 5, a hot runner plate 6, and an A plate 7. A front mold core 1 is set inside the A plate. The product 4 with the quick connector 13 is set inside the front mold core 1. A spring block 11 and a spring block insert 12 are set above the quick connector. The spring block and the spring block insert are inclined relative to the horizontal plane. The spring block is driven by a spring block seat 8 set inside the hot runner plate. When the mold is opened, the spring block 11 and the spring block insert 12 are driven by the spring block seat 8 to open the mold. The A plate 7 and the front mold core 1 do not move. After the spring block 11 and the spring block insert 12 are opened, the A plate 7 and the front mold core 1 open the mold again.

[0018] In one embodiment, a pressure block assembly is provided between the spring block seat 8 and the spring block 11. Specifically, the pressure block assembly includes a first pressure block 9 and a second pressure block 10, with a pin groove formed between the first pressure block and the spring block to accommodate the spring block insert pin.

[0019] In one embodiment, the top of the first pressure block forms a cavity to receive the tip of the spring insert. The upper part of the second pressure block forms a transverse groove, and the bottom of the spring holder forms a locking block that mates with the groove. The top of the spring holder is positioned on the hot runner plate by fastening screws.

[0020] The mold opening sequence of this utility model is as follows: the spring block 11 and the spring block insert 12 are driven to open the mold by the spring block seat 8.

[0021] Plate A7 and front mold core 13 remain stationary. After the spring block 11 and spring block insert are opened, Plate A7 and front mold core 1 are opened again to complete the mold opening process.

[0022] The mold closing sequence is as follows: Plate A 7 and front mold core 1 close. Spring block 11 and spring block insert 12 remain stationary. Spring block 11 and spring block insert 12 are driven to close by spring block seat 8, thus completing the entire mold closing process.

[0023] This invention adds a front mold spring block and a front insert pin that are inclined to the horizontal plane at the quick connector of the product. The spring block is molded first and then the whole mold is molded, which solves the problem of the quick connector tilting after injection molding and meets the product requirements.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. In short, if a person skilled in the art is inspired by it and designs a similar structure and embodiment without departing from the general concept of the present utility model, it shall fall within the protection scope of the present utility model.
