Description

Technical Field

[0001] The utility model relates to a dewaxing transfer vehicle. Background Art

[0002] The lost wax casting method is to make wax into the shape of the desired mold, then pour high-temperature resistant fine mud onto the surface of the wax mold, and sprinkle fine sand on the surface of the mud. This is repeated many times to form a complete mold shell. After drying, it is heated to melt the wax and form a mold cavity for casting.

[0003] During mold dewaxing, multiple molds need to be transported to the dewaxing machine via a transfer vehicle for heating and melting. Traditional transfer vehicles can only deliver the molds to the dewaxing machine's feed port, where workers then transfer the molds one by one from the transfer vehicle to the dewaxing machine. This wastes time and manpower, resulting in low work efficiency. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] like Figures 1 to 5 As shown, this embodiment provides a dewaxing transfer vehicle, comprising a mobile cart 1, a loading platform 2 of the mobile cart having wheel rails 3 symmetrically fixed thereon extending forward and backward, a transfer frame 5 with moving wheels 4 at the bottom being provided on the wheel rails, a grid-type storage platform being fixed on the transfer frame, and a filter screen 6 fixed to the transfer frame being provided directly below the storage platform; the wheel rails are both first angle irons placed with their openings facing downwards.

[0025] 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.

[0026] In the embodiment of the present invention, the transfer frame is rectangular in shape, and the storage platform is fixedly arranged horizontally inside the transfer frame. The storage platform is composed of a plurality of transverse support plates 12 spaced apart in the front and back directions.

[0027] In an embodiment of the present invention, the filter screen is fixed horizontally inside the transfer frame.

[0028] In an embodiment of the present invention, 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.

[0029] In an embodiment of the present invention, the movable wheel has a wheel groove on its circumference for the top tip of the first angle iron to be embedded.

[0030] In an embodiment of the present invention, a positioning pin assembly is provided between the transfer frame and the mobile cart.

[0031] In an embodiment of the present utility model, the positioning pin assembly includes an upper sleeve 13 axially and vertically fixed to the middle of the rear outer end of the transfer frame, and a lower sleeve 14 axially and vertically fixed to the middle 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.

[0032] When the transfer frame on the mobile cart needs to be temporarily positioned, the latches can be inserted into the upper and lower sleeves to temporarily limit the forward and backward movement of the transfer frame on the mobile cart, facilitating the stability of the transfer frame during the movement of the mobile cart. However, the latches must be removed before pushing the transfer frame into the dewaxing machine.

[0033] In an embodiment of the present invention, the dewaxing transfer vehicle is used to transfer the dewaxing of the mold shells by a mobile cart. The transfer frame is placed on the loading platform of the mobile cart and can be moved back and forth on the wheel rails by the mobile wheels. When in use, multiple mold shells (the dewaxing ports of the mold shells are facing downwards) are placed on the storage platform of the transfer frame. When placed, the dewaxing ports of the mold shells are located on the gaps between adjacent transverse support plates to facilitate the downward flow of the wax liquid. The transfer frame is located on the loading platform of the mobile cart. When the mobile cart carries the transfer frame and the mold shells thereon to the feed port of the dewaxing machine, the entire transfer frame together with the multiple mold shells can be pushed into the interior of the dewaxing machine. During dewaxing, the wax melts out and flows along the grid-type storage platform and the filter net to the bottom of the dewaxing machine for collection. After the dewaxing is completed, the entire transfer frame together with the multiple mold shells is pushed out, thereby improving work efficiency.

[0034] In an embodiment of the present invention, the feed port of the dewaxing machine is located on the side of the dewaxing machine, and a switch door is provided on the feed port. The interior of the dewaxing machine is provided with a chamber for accommodating the transfer frame. The bottom of the chamber is at the same height as the loading table on the mobile cart, which facilitates the pushing in of the transfer frame.

[0035] In an embodiment of the present invention, a second angle iron 8 with its opening facing downward is fixed to the front end of the first angle iron. The two outer walls of the second angle iron are tightly attached to the two inner walls of the first angle iron, and the front end of the second angle iron is located in front of the front end of the first angle iron.

[0036] In an embodiment of the present invention, the front end of the second angle iron is provided with a chamfer, so that the second angle iron can be inserted into the angle iron connecting track 9 on the bottom of the internal chamber of the dewaxing machine, thereby facilitating the docking of the first angle iron and the connecting track.

[0037] In this embodiment of the utility model, the bottom of the chamber is symmetrically fixed with connecting rails extending forward and backward. The connecting rails are also made of angle irons and have the same specifications as the first angle irons. Before pushing the transfer frame into the dewaxing machine, the mobile cart is first pushed so that the second angle iron at its front end is aligned with the end of the connecting rail and embedded, thereby achieving docking between the first angle iron and the connecting rail, and facilitating the transfer frame to be pushed from the first angle iron to the connecting rail.

[0038] 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.
