Mould shell dewaxing box

Technical Field

The utility model relates to an investment casting's precision casting equipment technical field, concretely relates to mould shell dewaxing case.

Background

Investment casting, also known as lost wax casting, is a common practice in precision casting. Usually, wax liquid is selected to manufacture a wax mould, refractory coating is repeatedly coated and hung on the wax mould, refractory sand is scattered, the wax mould is hardened and dried, and then the mould shell is dewaxed (namely, the wax inside is melted away at high temperature); thereafter, a shell mold having sufficient strength without residual wax is obtained by firing to pour the molten metal, thereby obtaining a casting with high accuracy.

Dewaxing of a formwork typically occurs in a dewaxing kettle. When dewaxing, the door of the dewaxing kettle needs to be opened manually, the carrier vehicle is taken out, the formwork shell is placed on the carrier vehicle, and finally the carrier vehicle is pushed into the dewaxing kettle manually and the door is closed. The dewaxing process needs more manual operation steps; in addition, when the formwork is large in size and heavy in weight and the number of the formworks needing to be demolded at a time is large, an operator needs to spend a large amount of effort to push the transport vehicle in. In addition, the waste wax material produced in the dewaxing process is directly thrown away after the dewaxing of the common dewaxing kettle, and the waste material cannot be collected, so that the waste of raw materials is caused.

The specific implementation mode is as follows:

in order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:

referring to fig. 1 to 3, the mold shell dewaxing box comprises a box body 1 connected with a steam generating device, wherein the box body 1 dewaxes a wax mold in the mold shell by hot steam. The box door 11 of the box body 1 is connected with a conveying plate 2 which pushes the mould shell into the box body 1, and the outer side of the box door 11 is provided with a driving device 3 which controls the box door 11 to move forwards or backwards. The door 11 and the transport plate 2 are connected to each other, and the driving device 3 controls the door 11 to move forward or backward. The box body 1 is provided with a supporting frame 4 for installing the driving device 3 at the outer side of the box door 11. The driving device 3 comprises a motor 31 arranged outside the door 11 and two driving wheels 32 arranged at the bottom of the door 11, wherein the motor 31 is connected with the driving wheels 32 through a chain transmission assembly. The box body 1 is provided with a driving wheel guide rail 33 corresponding to the driving wheel 32 at the outer side of the box door 11. The bottom of the other side of the transport plate 2 opposite to the door 11 is provided with a driven wheel 34, and a driven wheel guide rail 35 corresponding to the driven wheel 34 is arranged in the box body 1. The chain transmission assembly comprises a transmission chain 36, a transmission gear 37 and a transmission rod 38, wherein the transmission chain 36 is connected with the motor 31, the two driving wheels 32 are arranged at two ends of the transmission rod 38, and the transmission gear 37 is sleeved on the transmission rod 38 and movably connected with the transmission chain 36. The motor 31 rotates clockwise or counterclockwise by controlling the transmission chain 36, and the transmission chain 36 drives the transmission gear 37 to rotate. Because the transmission gear 37 is fixedly connected with the transmission rod 38, the transmission rod 38 drives the two driving wheels 32 to reciprocate back and forth on the driving wheel guide rail 33, and simultaneously the driving wheels 32 drive the driven wheels 34 to reciprocate back and forth on the driven wheel guide rail 35, so that the automation of the forward movement or the backward movement of the conveying plate 2 is realized, the manual operation is reduced, the time and the labor are saved, and the production cost of an enterprise is reduced.
