Description

Technical Field

[0001] This application relates to the field of molds, and more particularly to a mold for a bathroom wall panel connector. Background Technology

[0002] Injection molds are the core tools for producing plastic products. They inject molten plastic into the mold cavity under high pressure, and after cooling and solidification, a precisely shaped product is obtained. In the field of integrated bathroom manufacturing, wall panel connectors, as key functional components, must meet the requirements of high dimensional accuracy, high-strength joint surfaces, and complex thin-walled structures.

[0003] Traditional molds consist of an upper mold assembly and a lower mold assembly, and rely on double-sided inclined guide pillars and a slider structure to demold the product. However, traditional molds are relatively large, which means that the molding machine also needs to be large in tonnage, resulting in drawbacks such as high energy consumption and large footprint for the production of small products. Utility Model Content

[0004] To reduce mold size, this application provides a mold for bathroom wall panel connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bathroom wall panel connector mold includes an upper mold assembly and a lower mold assembly. The upper mold assembly, facing the lower mold assembly, includes a fixed plate, a fixed template, and a fixed mold core plate. The fixed plate has an injection port. The lower mold assembly, facing the upper mold assembly, includes a base, an ejector mechanism, a movable template, and a movable mold core plate. The movable mold core plate has a plastic groove on the side facing the fixed mold core plate. When the mold is closed, the fixed mold core plate and the plastic groove form a plastic cavity for product molding. A slidable ejector assembly is slidably connected inside the fixed mold core plate. The upper mold assembly has a fixed mold spring that abuts against one end of the slid ejector assembly. When the mold is closed, the other end of the slid ejector assembly is located inside the plastic groove and forms the sidewall of the plastic cavity. When the mold is separated, the fixed mold spring drives the slid ejector assembly to move in the form of abutting against the movable mold core plate. During this movement, the end of the slid ejector assembly on the movable mold core plate gradually slides away from the plastic groove until it detaches from the product and separates from the movable mold core plate.

[0007] By adopting the above technical solution, during mold parting, the fixed mold spring releases its compressed elastic force, providing driving force to the inclined ejector assembly. This ensures that the inclined ejector assembly remains in contact with the gradually moving moving mold core plate during the initial stage of mold parting. During this process, the end of the inclined ejector on the moving mold core plate gradually slides away from the plastic groove until it detaches from the product and separates from the moving mold core plate in the later stages of mold parting. Through the cooperation of the spring and the inclined ejector assembly, compared to the traditional inclined guide pillar and slider structure, the mold size can be effectively reduced.

[0008] Optionally, a limiting groove is provided on the side of the fixed template facing the fixed mold core plate, and the inclined top assembly includes a limiting block located in the limiting groove and in contact with the fixed mold spring, the limiting block being slidably connected in the limiting groove.

[0009] By adopting the above technical solution, the setting of the limiting block ensures a good contact area between the fixed mold spring and the inclined ejector assembly, thereby stably releasing the elastic force of the fixed mold spring. The limiting groove, while limiting the limiting block, also provides corresponding space for its movement.

[0010] Optionally, the inclined top assembly further includes an inclined guide post connected to the limiting block. The inclined guide post is inclinedly inserted into the fixed model core plate, and a side core plate is provided on the side of the inclined guide post facing the moving model core plate.

[0011] By adopting the above technical solution, the force received by the limiting block is transmitted to the inclined guide post through the connection between the limiting block and the inclined guide post, causing the inclined guide post to slide along its inclined direction; through the design of the inclined guide post obliquely passing through the template and being integrally connected with the side core plate, the force received by the inclined guide post is decomposed into horizontal and vertical forces, so that the side core plate can be smoothly separated from the product and will not bring the product out of the plastic tank.

[0012] Optionally, the plastic cavity is configured as multiple, and the multiple plastic cavities are divided into several groups of different models.

[0013] By adopting the above technical solution, and by setting up multiple plastic cavities and dividing them into different groups, the mold can simultaneously inject and mold multiple products of different specifications and models.

[0014] Optionally, the moving model core plate has flow channels, which include a main channel and multiple branch channels that are interconnected. The multiple branch channels are connected to the plastic cavity. The moving model core plate is provided with multiple flow-stopping components that can block the connection between the corresponding branch channels and the plastic cavity.

[0015] By adopting the above technical solution, the connection between the corresponding branch channel and the plastic cavity can be opened or cut off by the flow-stopping component, so that the mold can dynamically allocate production capacity according to the demand and control production costs.

[0016] Optionally, the moving mold core plate has a rotating groove at the support channel, and the flow-stopping component includes a flow-stopping column connected in the rotating groove. The upper end face of the flow-stopping column has a flow groove that communicates with the support channel. When the mold is closed, the upper end face of the flow-stopping column abuts against the fixed mold core plate. The connection between the flow groove and the support channel can be adjusted by rotating the flow-stopping column.

[0017] By adopting the above technical solution, the connection between the flow channel and the branch channel can be adjusted by rotating the stop column. Its structure is simple and easy to operate.

[0018] Optionally, the upper end face of the flow-stopping column has two anti-rotation grooves, and the moving model core plate is provided with an anti-rotation screw threadedly connected to it. The anti-rotation screw cooperates with the anti-rotation groove to fix the flow-stopping column.

[0019] By adopting the above technical solution, the anti-rotation screw and the anti-rotation groove can be used to fix the flow-stopping column, which has a simple structure and is easy to operate.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By incorporating a fixed mold spring within the fixed mold platen and designing a linked inclined ejector assembly, the flexible elastic force released by the fixed mold spring directly drives the inclined ejector assembly to slide within the fixed mold core plate, completing the demolding action. Compared to the traditional slider mechanism that relies on a slider and inclined guide pillar for drive in molds, this significantly simplifies the mold structure, eliminates the lateral slider mechanism itself and its required installation space, thereby directly and effectively reducing the overall size and complexity of the mold, and lowering manufacturing costs and maintenance difficulty.

[0022] 2. The mold achieves dynamic capacity allocation by incorporating multiple grouped cavities supporting the simultaneous manufacturing of different product models and an adjustable runner system. The flow-stopping assembly allows operators to quickly open or close specific runners by rotation, selectively activating cavities according to order requirements. This not only improves production efficiency but also enables the molding of multiple product specifications in a single operation, reducing production costs. Attached Figure Description
