Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and particularly relates to a front template of a horizontal two-platen turntable two-color injection molding machine. Background Art

[0002] An injection molding machine, also known as an injection molding press or an injection machine, is the main molding equipment for making various shaped plastic products by using a plastic molding die for thermoplastic or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. The front template of a horizontal two-platen turntable two-color injection molding machine is one of the core components of the injection molding machine, and its functions include installing the mold, connecting the injection unit and driving the moving template to move, etc.

[0003] The authorized patent with the application number: CN202122515330.2 is known. It discloses a front template of an injection molding machine that is convenient for installing and fixing the mold. Its background art proposes the problem that "since the injection molding machine is a large-scale machine, it is extremely inconvenient for workers to operate, and there are certain risks. For the installation of one mold, it takes at least 30 minutes for two technicians at the fastest, which is time-consuming. At the same time, the same amount of time is required for mold removal, thus reducing the work efficiency of the factory. At the same time, the intensity of mold removal and installation is relatively high, greatly increasing the work intensity of technicians". For this reason, the technical solution of this scheme to solve this problem is "including a base, an injection cavity, a front template, an auxiliary entry component, and a clamping and fixing component. The injection cavity is fixed at the upper end of the base. A guide rail is fixed inside the injection cavity, and the guide rail extends along the length direction of the injection cavity. The front template is slidably connected to the outside of the guide rail. One end of the front template is connected with a mold clamping mechanism, and the auxiliary entry component is arranged at the end far from the mold clamping mechanism. The clamping and fixing component is detachably connected to both sides of the front template", etc.

[0004] However, in the implementation of the related technology, it is found that the existing technical solutions have the following problems: during the high-speed mold opening and closing process, the front template will bear huge pressure, and the structural strength of the existing front template of the injection molding machine is poor, making it difficult to provide sufficient service strength. At the same time, in order to meet the requirements of different specifications of mold sizes, the mold positioning holes of the front template should be diversified, while the structure of the existing mold positioning holes of the front template is relatively simple and single, making it difficult to meet the needs of different types of molds, thus reducing the use effect and applicability of the front template.

[0017] Preferably, a moving oil cylinder mounting plate is fixedly installed on the front side of the front template body.

[0018] Preferably, two manipulator mounting plates are symmetrically and fixedly installed at the top of the front template body.

[0038] The technical solution provided by this embodiment is: when in use, by setting the first reinforcing rib 3 and the second reinforcing rib 4, the structural strength of the front template body 1 in the left-right and up-down directions can be enhanced. At the same time, under the action of the reinforcing bars 6, it is convenient to increase the structural stability at the four corners of the front template body 1, so that it has a good supporting effect, can disperse the concentrated stress received by the front template body 1, make it evenly stressed, improve the overall anti-deformation ability of the front template body 1, and with the cooperation of the weight-reducing groove, the front template body 1 can achieve the effect of reducing weight and saving costs while also providing sufficient strength, which is beneficial to improving the structural rigidity and strength of the front template body 1. At the same time, by setting the mold middle positioning hole 8, it is convenient to assemble and apply to a single injection station. The two mold side positioning holes 7 can jointly apply to a double injection station. By changing the hole distance size of the two platen positioning rings 9 according to requirements, the mold center distance between the two mold side positioning holes 7 can be changed, making the mold positioning holes diverse, so that the front template body 1 can adapt to the installation requirements of a single injection station and multi-size double injection stations.
