The die structure is simplified, the die size is reduced, and the die cost and the production and operation cost are reduced.

Description

Technical Field

[0001] This utility model relates to a demolding structure for water chamber product connectors, and in particular to a left-right opposing slider core-pulling structure. Background Technology

[0002] For water-chamber type products, double-angled pipe connections are common, forming a pipe groove at the pipe opening, thus requiring structural demolding. Currently, the demolding structure used for this type of pipe fitting is an upper and lower core-pulling structure, such as... Figure 1 and Figure 2 As shown, it includes a spring plate 1, a fastening structure, a spring 3, and a pull rod 4; a front mold core puller and a rear mold core puller are respectively set on the upper and lower parts of the product, and a slider is set on the axial direction of the product. The slider is controlled by the shovel to move.

[0003] Before the mold is opened, the AB plate is kept still by the buckling mechanism 2. The spring plate 1 starts to move under the action of the spring 3, which drives the front mold core pulling 5 to start demolding. The pull rod 4 is in place, the front mold is demolded, the buckling mechanism 2 is opened, the slider 9 starts to move, which drives the scraper 8 to start pulling the core, and the rear mold core pulling 7 starts to demold, realizing the smooth demolding of the tube opening.

[0004] The drawback of this mold is its increased complexity, which raises mold costs, increases the difficulty of mold matching, and leads to a sharp increase in production and operating costs. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model proposes a left-right opposing slider core-pulling structure, which simplifies the mold structure, reduces the mold size, and lowers mold cost and production and operation costs.

[0006] Therefore, the technical solution adopted by this utility model is: a left and right opposing slider core-pulling structure, including opposing sliders, characterized in that the opposing sliders include a left slider and a right slider provided on the side of the product, the left slider and the right slider are symmetrically arranged and matched with the product's pipe slot structure, and also include a large slider for opening the mold at the center of the pipe opening.

[0007] Preferably, the left and right sliders are driven by the inclined guide post to perform lateral displacement.

[0008] Preferably, the large slider is driven by a bent pin to perform the overall mold opening action.

[0009] Preferably, the left and right sliders are mounted on the large slider.

[0010] This invention employs a left-right opposing slider structure to replace the top-bottom core-pulling structure for demolding, eliminating the need for spring plates and locking mechanisms. Instead, it uses inclined guide pillars to drive the left and right sliders, simplifying the mold structure, reducing mold size, and lowering mold and production operating costs. This invention can shorten the production cycle, simplify mold assembly, and improve product quality. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 3-4 The left and right opposing slider core-pulling structure shown includes opposing sliders, including a left slider 12 and a right slider 10 located on the side of the product 6. The left and right sliders are symmetrically arranged and match the product's pipe slot structure. It also includes a large slider 13 for opening the mold at the center of the pipe opening. The upper part of the large slider is positioned to match the pipe opening for core pulling.

[0019] Specifically, the left slider 12 and the right slider 10 are driven by the inclined guide post 11 to perform lateral displacement.

[0020] Specifically, the large slider 13 is driven by the bent pin 14 to perform the overall mold opening action. In the initial state, the core-pulling slider 13 remains stationary under the action of the bent pin 14.

[0021] Specifically, the left slider 12 and the right slider 10 are mounted on the large slider 13. This ensures that the various sliders are tightly connected to each other, resulting in a more compact structure.

[0022] The mold opening process of this utility model is as follows: When the mold opens, the inclined guide post 11 moves upward, and the left and right sliders begin to move outward respectively under the drive of the inclined guide post. The large slider 13 remains stationary under the action of the bent pin 14, the left slider 12 and the right slider 10 are completely demolded, and the large slider 13 begins to move under the drive of the bent pin 14, realizing the overall mold opening.

[0023] The mold closing process is as follows: the upper and lower molds close, the bent pin 14 moves, and the bent pin 14 drives the large slider 13 to start moving, and the slider is in place. The inclined guide post 11 drives the left slider 12 and the right slider 10 to start resetting, completing the mold closing.

[0024] This invention employs a left-right opposing sliding block structure to replace the top-bottom core-pulling structure for demolding, eliminating the need for spring plates and locking mechanisms, thus simplifying the mold structure, reducing mold size, and lowering mold and production operating costs. It can shorten the production cycle, simplify mold assembly, and improve product quality.

[0025] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
