Description

Technical Field

[0001] The utility model relates to the technical field of injection molding assembly tooling, in particular to a string assembly platform for a mold clamping device of an injection molding machine. Background Art

[0002] Injection molding machines, also known as injection molding machines or injection machines, are also called beer machines in many factories, and injection molded products are correspondingly called beer parts. The injection molding machine is mainly used to use thermoplastics or thermosetting plastics to make plastic products of various shapes using plastic molding molds.

[0003] The working principle of an injection molding machine is similar to that of a syringe. Using the thrust of a screw or plunger, the plasticized, molten plastic (i.e., a viscous, fluid state) is injected into a closed mold cavity. After solidification and finalization, the finished product is obtained. Each injection molding machine's production process is a cycle, consisting of the following steps: dosing, melt plasticization, pressure injection, mold filling and cooling, and mold opening and part removal.

[0004] Accordingly, the core structure of an injection molding machine usually includes the injection unit, mold clamping unit, hydraulic system, and electrical control system. The injection unit and mold clamping unit are the key components of the injection molding machine. The injection unit is responsible for injecting molten plastic into the mold, while the mold clamping unit is responsible for opening and closing the mold.

[0005] The mold-closing assembly platform for injection molding machines is an essential piece of equipment in the assembly process. It's primarily used to support and secure the mold, ensuring a smooth mold-closing process. Specifically, it firmly supports the mold, preventing it from moving or deforming during the injection process. Furthermore, through precise design and manufacturing, this type of assembly platform ensures accurate mold alignment during installation, guaranteeing the dimensional accuracy of the molded product.

[0006] Based on this, Chinese patent CN216182326U discloses an injection mold assembly platform, which includes: a bracket, a plurality of parallel and spaced track beams fixedly arranged on the upper end surface of the bracket along the longitudinal direction; a platform plate, the platform plate is arranged above the track beam and has at least three cavities; a trolley, the trolley is arranged in the cavity and is connected to the upper end surface of the track beam in a sliding manner; a slewing bearing, the slewing bearing is fixedly arranged on the top of the trolley; a bearing plate, the bearing plate is fixedly arranged on the top of the slewing bearing. By setting the slewing bearing, the template can be rotated. No matter where the template is placed on the bearing plate, it can be rotated so that the three templates can be adjusted to a parallel state; by moving the trolley on the track beam, the three templates are adjusted to the same axis position, ensuring that the through holes are concentric and the positioning is accurate, so as to ensure that the injection molding machine can operate normally and effectively in terms of mold closing.

[0007] However, the injection mold assembly platform disclosed above still has the technical problem of being unable to conveniently adjust the spacing between assembly modules. Specifically, in the existing technical solution of the injection mold assembly platform for stringing together three templates, the injection mold assembly platform has a relatively slow assembly speed when assembling each template component. This is because, in the existing design solution, workers need a longer time to assemble the required mold clamping device. The core technical problem is that factors such as fixed pin hole positioning dimensions and assembly height will have an adverse effect on the mold clamping device of the injection molding machine for large mold assembly. At this time, it is often necessary to use a fixed model string assembly platform for adaptation to ensure the accuracy and stability of the workers during installation, which affects the speed of assembly and reduces the versatility of the tooling. Utility Model Content

[0008] Based on this, it is necessary to provide an injection molding machine mold clamping device serial assembly platform to address the technical issues of how to improve the assembly convenience and tooling versatility of the injection molding machine mold clamping device.

[0009] A serial assembly platform for a mold clamping device of an injection molding machine comprises: a support frame, a head plate positioning pad structure, a tail plate positioning pad structure, a transmission line rail structure and an adjustable pad structure; the head plate positioning pad structure and the tail plate positioning pad structure are respectively arranged on both end sides of the support frame relative to each other; the transmission line rail structure is arranged on the support frame between the head plate positioning pad structure and the tail plate positioning pad structure, and the adjustable pad structure is movably connected to the transmission line rail structure.

[0010] Furthermore, the support stand has a base, a guide matching structure and a support positioning structure; a plurality of the guide matching structures are evenly arranged on both end sides of the base, and a plurality of the support positioning structures are evenly distributed on the side faces of the base.

[0011] Furthermore, the head plate positioning pad structure has a first head plate positioning block, a second head plate positioning block and several head plate positioning parts; the first head plate positioning block and the second head plate positioning block are relatively spaced apart and arranged on the same end side of the base; the first head plate positioning block or the second head plate positioning block is distributed with several of the head plate positioning parts.

[0012] Furthermore, the tailgate positioning pad structure comprises a tailgate positioning block and a plurality of tailgate positioning structures.

[0013] Furthermore, the two tail plate positioning blocks are relatively arranged on one end side of the base, and each tail plate positioning block is paired with the first head plate positioning block or the second head plate positioning block; and a plurality of tail plate positioning structures are evenly distributed on each tail plate positioning block.

[0014] Furthermore, the two groups of transmission linear rail structures are arranged relatively parallel to each other on the support frame, and each group of transmission linear rail structures is movably connected to one of the adjustable pad structures.

[0015] Furthermore, each group of the transmission linear rail structures is provided with a linear rail unit and a plurality of transmission positioning structures; the two linear rail units are arranged relatively parallel on the base, and the plurality of transmission positioning structures are evenly spaced between the two linear rail units, and each transmission positioning structure is correspondingly arranged in the base.

This allows for the positioning of the mold's movable platen within the fixture, in conjunction with locating pins and other components. The relative placement of the two sets of movable platen spacer units 501 allows the spacer to carry a maximum load of 3000kg. Furthermore, additional spacers can be used to position the movable platens of various injection molding machine models with hole center distances between 730mm and 1000mm.

[0038] Specifically, when the movable plate needs to be assembled, it can move between the head plate positioning pad structure 2 and the tail plate positioning pad structure 3. The movable plate pad unit 501 can be driven to make the sliding connection block 503 provided thereunder move back and forth along the limit of the linear rail unit 401 until it reaches the required position.
