Description

Technical Field

[0001] This utility model relates to the field of wax injection equipment technology, and in particular to a wax injection molding device. Background Technology

[0002] In the investment casting industry, the traditional wax pattern preparation process is achieved through wax injection machines. These wax injection machines are fixed and do not move. However, due to the short wax injection time and the long auxiliary time, the utilization rate of the wax injection device is low, and the working efficiency of each wax injection machine is also very low. There is a need in the market for a wax injection machine with high utilization and high efficiency.

[0003] Currently, wax injection machines cannot use a single wax injection device to achieve both side injection and top injection methods. They also cannot automatically adjust the position of the wax injection device after the wax injection position of the mold changes. Furthermore, a single wax injection machine cannot store two or more different wax materials at the same time, nor can it select different wax storage tanks to supply wax materials to the corresponding wax injection cylinder according to wax injection needs. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a wax injection molding device, which aims to improve the situation where a single wax injection device cannot achieve both side injection and top injection methods. It also enables automatic adjustment of the wax injection device position after the wax injection position of the mold changes, and addresses the issue that a single wax injection machine cannot simultaneously store two or more different wax materials. According to the wax injection needs, different wax storage tanks are selected to supply wax materials to the corresponding wax injection cylinder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wax injection molding device, comprising a base and a support, a bearing column fixedly connected to the front of the support, a gear rollingly connected to the bearing column, a rack meshing with the side of the gear, one side of the rack fixedly connected to a lifting rod, a horizontal plate fixedly connected to the side of the lifting rod away from the gear, and a wax injection gun fixedly connected to one end of the horizontal plate.

[0006] The back of the bracket is connected to a load-bearing frame by bolts and threads. A constant temperature chamber is installed above the load-bearing frame. The constant temperature chamber is flexibly connected to the wax injection gun through a conduit.

[0007] As a further description of the above technical solution:

[0008] The base is provided with a slide rail, and a slider is slidably connected to the slide rail. A diagonal rod is threadedly connected to the slider by bolts. The diagonal rod is threadedly connected to the bracket. A conveyor belt is fixedly connected to the bottom of the bracket, and the two sides are fixed to the slider.

[0009] As a further description of the above technical solution:

[0010] The top of the wax injection gun is equipped with a top injection head, a side injection head, and a nut. The injection head is equipped with an injection nozzle, and an adjuster is located next to the injection nozzle.

[0011] As a further description of the above technical solution:

[0012] The conduit has a threaded elastic structure and is made of corrosion-resistant material.

[0013] As a further description of the above technical solution:

[0014] A switch is provided on the side of the base, and a support leg is fixedly connected to the bottom of the base.

[0015] As a further description of the above technical solution:

[0016] The bracket has fixing frames on both sides, and motors are mounted on the fixing frames.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the wax injection machine is movable. Because the wax injection time is short and other auxiliary times are short, the wax injection device has a high utilization rate and the working efficiency of each wax injection machine is also very high.

[0019] 2. In this utility model, the problem of not being able to use a single wax injection device to achieve both side injection and top injection wax injection is solved. It achieves automatic adjustment of the position of the wax injection device after the wax injection position of the mold changes, and addresses the limitation of a single wax injection machine being unable to store two or more different wax materials at the same time. It also improves the ability to select different wax storage tanks to supply wax materials to the corresponding wax injection cylinder according to wax injection needs. Attached Figure Description
