Description

Technical Field

[0001] The utility model relates to a shell dewaxing material feeding and discharging structure. Background Art

[0002] The lost wax casting method involves shaping wax into the desired mold shape. A fine, heat-resistant slurry is then poured onto the wax surface, and fine sand is sprinkled on top. This process is repeated repeatedly to form a complete mold shell. After drying, the shell is heated to melt the wax, forming a cavity for casting. During the dewaxing process, multiple shells must be transported to a dewaxing furnace via a transfer vehicle for heating and melting the wax. Traditional transfer vehicles can only deliver the shells to the furnace's feed port, where staff must transfer the shells individually from the transfer vehicle to the furnace. This wastes time and labor, resulting in low efficiency.

[0003] Based on this, in order to improve work efficiency, this case has set up a transfer frame that can be pushed into the dewaxing furnace as a whole through technical transformation. In the process of pushing the transfer frame into the dewaxing furnace, corresponding wheel rails need to be set on both the dewaxing furnace and the mobile cart. However, there is a problem that the connection between the wheel rails of the mobile cart and the wheel rails of the dewaxing furnace is not accurate or difficult to connect, which in turn affects the pushing of the transfer frame.

[0033] The dewaxing furnace includes a heating furnace body, and a second wheel rail 9 extending forward and backward is fixedly provided on the bottom of the heating furnace body in a symmetrical manner. The second wheel rail is a third angle iron with an opening facing downward, and the end cross-sectional size of the third angle iron is the same as the end cross-sectional size of the first angle iron, so as to facilitate a one-to-one connection between the second wheel rail and the first wheel rail.

[0034] In an embodiment of the present invention, a grid-type storage platform is fixedly provided on the transfer frame, and a first filter 6 fixed on the transfer frame is provided directly below the storage platform.

[0035] In the embodiment of the present invention, universal wheels 10 with brakes are installed at the upper left corner, lower left corner, upper right corner and lower right corner of the bottom of the loading platform of the mobile cart, and a cart handrail 11 is fixed to the rear end of the loading platform.

[0036] In an embodiment of the present invention, the transfer frame is rectangular in shape, the storage platform is horizontally fixed inside the transfer frame, and the storage platform is composed of a number of transverse support plates 12 spaced apart in the front and back; the first filter is horizontally fixed inside the transfer frame; there are four moving wheels, which are respectively installed at the upper left corner, lower left corner, upper right corner, and lower right corner of the bottom of the transfer frame.

[0037] In an embodiment of the present invention, the movable wheels are provided with wheel grooves on their circumferences to facilitate cooperation with the first and second wheel rails.

[0038] In an embodiment of the present utility model, a positioning pin assembly is provided between the transfer frame and the mobile cart; the positioning pin assembly includes an upper sleeve 13 axially and vertically fixed to the middle part of the rear outer end of the transfer frame, and a lower sleeve 14 axially and vertically fixed to the middle part of the rear outer end of the loading platform. The upper and lower sleeves are coaxial and have a vertical pin 15 inserted inside. A limiting handle 7 is vertically fixed to the top of the pin.

[0039] In an embodiment of the present invention, a chamfer is provided at the front end of the second angle iron.

[0040] In the embodiment of the present invention, an inlet and outlet port is provided on the front side of the heating furnace body, and a switch door panel 18 is hinged on the inlet and outlet port.

[0041] In the embodiment of the present invention, a wax collecting groove 19 is provided between the two second wheel rails at the bottom of the heating furnace body, and a second filter screen 20 is horizontally provided on the wax collecting groove.

[0042] In the embodiment of the present invention, the wax collecting groove is high on all sides and low in the middle, and a wax discharge port 21 is provided at the lowest position.

[0043] In the embodiment of the present utility model, the working principle of the shell dewaxing feeding and discharging structure is as follows:

[0044] The transfer frame is placed on the loading platform of the mobile cart and can be moved back and forth on the first wheel track via its wheels. During use, multiple mold shells (with the dewaxing ports facing downward) are placed on the transfer frame's storage platform, with the dewaxing ports positioned in the gaps between adjacent transverse support plates to facilitate the downward flow of wax. The transfer frame is located on the loading platform of the mobile cart. When the transfer frame needs to be temporarily positioned on the mobile cart, latches inserted into the upper and lower sleeves can temporarily restrict its forward and backward movement on the mobile cart, facilitating its stability during movement.

[0045] When the mobile cart carrying the transfer frame and the mold shells on it moves to the entrance and exit of the dewaxing furnace, the entrance and exit door panel opens. Before the first wheel rail is connected to the second wheel rail, the mobile cart is operated to insert the front end of the smaller second angle iron into the interior of the third angle iron, which serves as a guide for the wheel-rail connection and facilitates the quick and accurate connection between the first and second wheel rails. The latch is then unplugged, and the entire transfer frame, along with the multiple mold shells on it, is pushed into the interior of the dewaxing furnace along the first and second wheel rails. After the transfer frame is pushed into place, the latch is reinserted into the upper sleeve, and the bottom of the latch is inserted into any mesh on the second filter screen to temporarily position the transfer frame. The mobile cart is then pushed away and the door panel is closed. The heat inside the dewaxing furnace dissolves the wax liquid, which then flows down through the filter screen and roughly filters into the wax collection groove. The wax outlet is connected to a pipe to drain the wax liquid. After dewaxing is completed, open the switch door panel and operate the mobile cart again to connect the first and second wheel rails, and then the entire transfer frame together with the multiple mold shells on it are pushed out of the dewaxing furnace along the second and first wheel rails, which improves work efficiency.

[0046] In the embodiment of the present invention, the second filter screen has a certain thickness and a relatively strong overall rigidity, and the mesh holes thereon can be used as the bottom end of the pin for insertion.

[0047] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
