Abstract
Description
Technical Field
[0001] The present invention relates to a method of using vacuum suction to complete pouring a solution into a mold to cast jewelry and other utensils, and is mainly used in the field of equipment application technology of goldsmith shops and jewelry processing factories, and specifically is a suction rope device used in the process of casting reverse molded products including but not limited to jewelry, tea sets, Buddha statues, etc. Background Art
[0002] At present, there are three main ways for goldsmiths and jewelry factories to use molds (molds mainly include but are not limited to plaster molds) for jewelry reverse casting: 1. Oil mud compression molding method, put the material on the mold and melt it with a torch, and then use the oil mud to press the molten metal liquid into the mold; 2. Centrifugal casting method, put the material into a special crucible and melt it with a torch, then start the machine to rotate rapidly and throw the molten material liquid into the mold; 3. Vacuum suction rope casting method, the suction rope casting device is divided into a small suction rope machine and a large fully automatic integrated casting suction rope machine. The small suction rope machine is to put the mold into the suction rope device Place it on top or inside (the suction cable device is normally placed in two ways. The small mold is normally placed on the reserved hole of the suction cable device, and the reserved hole of the suction cable device is used to generate suction on the bottom of the mold. The large mold is normally placed inside the suction cable device, and suction is generated from the side and bottom of the mold, thereby sucking the molten material into the mold to complete the casting), put the material into a crucible or quartz bowl, melt it with a fire gun or a high-frequency machine, turn on the vacuum machine to absorb the vacuum, and then pour the molten material into the mold; the large-scale fully automatic integrated casting suction cable machine is a device similar to that described in patent number 202320039607. For on-site casting in goldsmith shops, the oil mud pressing method, centrifugal casting method and small suction cable devices are normally used for processing a small number of jewelry for scattered customers. For one-time production of multiple jewelry, jewelry processing factories normally use integrated vacuum suction cable devices similar to those described in patent number 202320039607 for casting. The above three casting methods require a preheating treatment of the mold before pressing, throwing in, and sucking the molten liquid. The preheating treatment uses a torch to directly heat the mold or uses a heating furnace to heat the mold to 650 to 750 degrees or the required temperature. After the mold is preheated, it is necessary to wait for the material to melt. During this waiting time, the mold temperature drops, and the specific mold temperature cannot be controlled. When operated by a single person, the mold must be preheated and the material must be melted and poured into the solution. The cumbersome operation requires the operator to be very skilled and the mold temperature is often insufficient or too high, resulting in defects such as broken wires and bubbles after the product is cast. Summary of the invention
[0003] In order to overcome the high cost of fully automatic vacuum casting machines and the inconvenience of casting small scattered jewelry; using the oil mud die pressing method, centrifuge casting method, and small suction cable casting method, the mold must be preheated before pouring the material solution into the mold. The mold preheating and material smelting need to be carried out step by step. The operation gap causes the mold temperature to be uncontrollable, which makes the molded product prone to defects such as broken wires and pores. The present invention provides a heating suction cable device composed of a metal insulation barrel, a temperature power controller, a heating coil, a fixing plate, and a heat-resistant gasket.
[0004] The technical solution adopted by the present invention to solve its technical problems is: a suction rope device using vacuum suction and heating, including a nut and a mold support plate to fix and press the mold and the mold heat-resistant gasket onto the barrel cover, and then use the nut and the heating ring support plate to place the heating ring at a position corresponding to the mold, and use a temperature power controller to set and control the temperature to be preheated to heat the mold.
[0005] The beneficial effects of the present invention are: a suction rope device that utilizes vacuum suction and heating can continuously heat the mold and control the precise temperature, thereby improving the success rate of casting products. In addition, the device of the present invention has a simple structure and reduces the user's equipment cost; it eliminates the tedious operation of preheating the mold with a blast gun or a heating furnace, the inability to monitor the temperature of the mold after it is placed on the suction rope device, and the three major factors that cause the mold temperature to drop while waiting for the material to melt, which cause defects in the cast product.

It is obvious that the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

If the vacuum machines are installed together to form a new device, it also belongs to another embodiment of the present invention). In this way, the assembly of each component before work is completed; after connecting to the external power supply through the temperature power controller 3 and setting the preheating temperature, the vacuum machine is turned on to absorb the vacuum after reaching the required temperature, and then the molten material is poured into the molten material through the feed hole 8 to complete the casting.
[0014] In this embodiment, the heating coil 16 is a ceramic heating coil, which can be disassembled and is not fixed on the metal insulation barrel 1. If other heating forms are used, such as far-infrared carbon fiber quartz heating tubes, heating wires, or the heating coil is fixed on the metal insulation barrel 1 by adding a variable frequency heating device, they all belong to other embodiments of the present invention; if the heating coil 16 is integrated with a temperature probe so that the temperature probe interface 5 on the metal insulation barrel 1 can be omitted, it also belongs to other embodiments of the present invention. The above-described situations all belong to other embodiments obtained without creative work, and all belong to the scope of protection of this disclosure.
