Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically relating to a solenoid valve filter. Background Technology

[0002] In the injection molding process of plastic parts for filters currently on the market, various rib structures are often designed on the plastic parts to meet the product's structural strength, assembly requirements, and functional characteristics. However, when some rib structures of the plastic parts have undercut features in the mold demolding direction, demolding becomes a very challenging problem. If the demolding problem is not properly solved, it will not only lead to defects such as tearing, deformation, or even breakage of the plastic parts during demolding, seriously affecting the product's quality and appearance, but may also reduce production efficiency and increase production costs. Utility Model Content

[0003] The purpose of this invention is to provide a solenoid valve filter that facilitates demolding through optimized rib structure design.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a solenoid valve filter, comprising a filter body, wherein the filter body is a rotating body with a central axis as the axis of rotation, having a connecting part and a filtering part coaxially connected in one piece, wherein the side wall of the filtering part is provided with filter mesh holes, and the inner wall of the connecting part is provided with a rib structure that surrounds a ring, wherein the surface of the rib structure is an arc surface.

[0007] Furthermore, the height of the rib structure is 1 / 5 of the wall thickness of the filter section.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can significantly reduce the deformation range of plastic parts and concentrate stress at the ribs, thereby reducing the risk of damage to functional areas, reducing demolding resistance, and preventing the ribs from scratching or breaking.

[0014] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figures 1 to 3 As shown, this utility model discloses a solenoid valve filter, manufactured using injection molding. The solenoid valve filter includes a filter body 1, which is a rotating body with its central axis as the axis of rotation. It has a connecting part 2 and a filtering part 3 that are coaxially connected as a single unit. The connecting part 2 is used for fixed connection with a solenoid valve, and the filtering part 3 is used for filtering the fluid medium.

[0016] The side wall of the filter section 3 is provided with filter mesh 4. The medium is filtered through the filter mesh 4 and then enters the internal flow channel of the solenoid valve. The inner wall of the connecting section 2 is provided with a rib structure 5 that surrounds the connection section 2. The surface of the rib structure 5 is curved. The rib structure 5 can improve the mechanical strength of the connecting section 2 after molding, and its curved surface structure will not generate resistance during demolding, thereby achieving rapid demolding.

[0017] As a preferred example, the filter section 3 is provided with four connecting posts 6 and hollow sections 7 disposed between the connecting posts 6, the hollow sections 7 being provided with filter mesh holes 4. The function of the connecting posts 6 is to improve the overall strength of the filter section 3 and prevent deformation and damage under repeated impact from the medium.

[0018] As a preferred example, the perforated portion 7 is provided with a plurality of weft ribs 8 and a plurality of warp ribs 9 for forming the filter mesh 4, with the warp ribs 9 located inside the weft ribs 8. The warp ribs 9 and the weft ribs 8 are arranged at 90° to form the filter mesh 4.

[0019] As a preferred example, the height W1 of the rib structure 5 is 1 / 5 of the wall thickness W2 of the filter section 3.

[0020] When demolding the solenoid valve filter of this utility model, the part of the rib structure 5 closest to the filter part 3 is demolded first, followed by the highest point of the rib structure 5, and finally the part of the rib structure 5 away from the filter part 3.

[0021] In this invention, during injection molding, suitable plastic particles are selected based on the working conditions of the plastic part. Considerations include, but are not limited to, particle flowability, tensile strain, and fracture strain. The plastic raw material is added to the injection molding machine barrel, heated and melted, and then injected into the space formed by the mold cavity and core under the push of the injection molding machine screw. Since the mold has been preheated to a suitable temperature, the plastic melt rapidly cools and solidifies within the cavity, forming a plastic part with an arc-shaped rib structure 5. The mold opens, and the upper and lower molds separate. The ejection mechanism begins to work, ejecting the plastic part from the core. After demolding, the plastic part cools and solidifies, and the product appearance is observed.

[0022] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0023] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
