Abstract

A spring-loaded ejector mold structure effectively solves the problem of difficult ejection of undercuts, which affects product quality. It includes a spring-loaded panel, with spring-loaded one and spring-loaded two fixed at the lower end of the spring-loaded panel. The cross-section of spring-loaded one and spring-loaded two is a semi-circular ring structure. Spring-loaded one and spring-loaded two are combined to form a cylinder. A straight ejector core is slidably connected inside the cylinder. A spring-loaded base plate is fixed at the upper end of the spring-loaded panel. The straight ejector core slides up and down inside the spring-loaded panel and the spring-loaded base plate. A limiting platform located above the spring-loaded base plate is fixed at the upper end of the straight ejector core. The limiting platform is fitted with an insert pressure block.

Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a spring-loaded release buckle mold structure. Background Technology

[0002] When demolding numerous plastic parts during injection molding, the issue of undercuts often arises. Undercuts are structural elements that "reversely wrap" around the mold, preventing the product from being easily demolded in one direction. Some plastic parts require multiple undercuts, with these structures located on the front and sides of the product. The complex undercut structure negatively impacts demolding quality. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a spring-loaded ejector mold structure that effectively solves the problem of difficult ejection of the undercut and the impact on product quality.

[0004] The technical solution to the technical problem is as follows: it includes a top panel, with a top panel 1 and a top panel 2 fixed at the lower end of the top panel. The cross-sections of the top panel 1 and the top panel 2 are both semi-circular ring structures. The top panel 1 and the top panel 2 are combined to form a cylinder. A straight core is slidably connected inside the cylinder. A bottom plate is fixed at the upper end of the top panel. The straight core slides up and down inside the top panel and the bottom plate. A limiting platform located above the bottom plate is fixed at the upper end of the straight core. An insert pressure block that cooperates with the limiting platform is installed on the bottom plate.

[0005] Preferably, the lower end of the straight core, spring tip one, and spring tip two form an inverted injection cavity.

[0006] Preferably, a plurality of springs are installed at the upper end of the spring top panel, and the springs pass upward through the spring top bottom plate.

[0007] This invention has the following advantages over traditional equipment: it has a clever structure and is easy to operate. The insert pressure block can limit the straight ejector core. When demolding is required, the insert pressure block is pulled out, and the straight ejector core moves upward out of the product. This frees up space for the undercut deformation, making it easy for the undercut to be forcibly demolded from between the spring ejector one and the spring ejector two. The product is made of plastic and has a certain degree of elasticity, which does not affect the undercut and product quality. It is safe, reliable, durable, and low in cost.

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 A spring-loaded release mold structure is provided, including a spring-loaded panel 1. Spring-loaded first 2 and spring-loaded second 3 are fixed at the lower end of the spring-loaded panel 1. The cross-section of spring-loaded first 2 and spring-loaded second 3 is a semi-circular ring structure. Spring-loaded first 2 and spring-loaded second 3 are combined to form a cylinder. A straight ejector core 4 is slidably connected inside the cylinder. A spring-loaded bottom plate 5 is fixed at the upper end of the spring-loaded panel 1. The straight ejector core 4 slides up and down inside the spring-loaded panel 1 and the spring-loaded bottom plate 5. A limiting platform 6 located above the spring-loaded bottom plate 5 is fixed at the upper end of the straight ejector core 4. An insert pressure block 7 that cooperates with the limiting platform 6 is installed on the spring-loaded bottom plate 5.

[0014] The lower end of the straight core 4, spring tip 2, and spring tip 3 form an inverted injection cavity 8.

[0015] To facilitate product demolding, multiple springs 9 are installed on the upper end of the spring top panel 1, and the springs 9 pass upward through the spring top bottom plate 5.

[0016] In use, after injection molding, an undercut is formed in the injection cavity 8. The mold is opened first, and under the action of the spring 9, the ejector plate 1, ejector base plate 5, ejector 1 2, ejector 2 3, straight ejector core 4 and insert pressure block 7 together push the product out first. Then the insert pressure block 7 is pulled out from the ejector base plate 5, and the insert pressure block 7 is released from the limiting platform 6. The limiting platform 6 is unrestrained, and the straight ejector core 4 moves upward in the cylinder. When the lower end of the straight ejector core 4 is completely separated from the undercut, the straight ejector core 4 stops moving. At this time, the straight ejector core 4 is withdrawn from the product, giving the product space for forced demolding. The product is made of plastic. The product drives the undercut away from ejector 1 2 and ejector 2 3. The undercut can deform in the cylinder, thus the undercut can be forcibly demolded without affecting the product quality, further improving the demolding quality of the product.

[0017] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
