Description

Technical Field

[0001] The utility model relates to a base frame, in particular to a wax piece base frame assembly. Background Art

[0002] Investment casting mainly consists of mold manufacturing, wax model manufacturing, shell mold manufacturing and subsequent drying, baking, pouring, solidification and other processes. The wax model is used to form the shape of the casting cavity. To obtain castings with high dimensional accuracy and surface finish, the wax model itself should have high dimensional accuracy and surface finish. The temperature of the wax model after it comes out of the furnace is high, and the wax model needs to be cooled.

[0003] At present, the wax model base is usually inserted into the groove on the wax model, and then the wax model base and the wax model are placed in water for cooling. However, the existing wax model cooling method has the following problems:

[0004] 1. When the wax model base is inserted into the wax model groove, it is easy to squeeze the wax model groove and cause the wax model to crack;

[0005] 2. Cooling in water can easily lead to unstable shrinkage of the wax model, affecting the dimensional accuracy of the wax model;

[0006] 3. After cooling, the wax model shrinks, causing the wax model base and the wax model to be too tight, which can easily cause the wax model to deform when pulling out the wax model base, and will cause swelling and pain in the operator's hands.

[0007] It can be seen that the current wax mold cooling method easily leads to reduced dimensional accuracy of the wax mold, as well as difficulty in mold insertion and removal. Utility Model Content

[0008] Based on this, it is necessary to provide a wax mold base assembly to address the above problems, so as to reduce the difficulty of inserting and removing the mold and ensure the dimensional accuracy of the wax mold.

[0009] The utility model provides a wax model base frame assembly, comprising a base, a support member and a plurality of base plates, wherein the support member is vertically fixedly connected to the base;

[0010] A plurality of slots adapted to the substrate are arranged on both sides of the support; one end of the substrate is detachably connected to the slot, and the other end of the substrate is inserted into the groove of the wax mold, and the thickness of the substrate is smaller than the width of the groove.

[0011] In one embodiment, the depth of the slot is equal to the thickness of the support member.

[0012] In one embodiment, the main body of the wax mold is below the substrate.

[0013] In one embodiment, the base, the support member and the substrate are all made of aluminum alloy.

[0014] In one embodiment, the support member is vertically plugged into the base.

[0015] In one embodiment, the thickness of the contact portion of the support member that contacts the base is smaller than the thickness of the portion of the support member that does not contact the base.

[0016] In one embodiment, the other end of the substrate is semicircular.

[0017] In one embodiment, the spacing between adjacent slots on the same side of the support member is greater than the spacing between adjacent slots on both sides of the support member.

[0018] In one embodiment, a smooth guiding surface is provided on the edge of the substrate.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The thickness of the substrate is smaller than the width of the wax mold groove, making it easy to insert the substrate into the wax mold groove, reducing the difficulty of inserting the mold and avoiding deformation of the wax mold;

[0021] 2. Use the base frame to naturally cool the wax model with air to ensure the wax model size shrinkage is stable and the wax model size accuracy is guaranteed;

[0022] 3. During natural cooling, the wax model's own weight is used to expand the groove opening to make it easier to insert the mold. At the same time, the expanded size offsets the shrinkage size of the wax model during cooling, making it easy to remove the wax model from the substrate after cooling, effectively avoiding deformation of the wax model caused by mold removal, reducing the difficulty of mold removal and ensuring the dimensional accuracy of the wax model.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] See also Figure 1 and Figure 2 , a wax model base frame assembly provided by an embodiment of the utility model comprises a base 1, a support member 2 and a plurality of base plates 3, wherein the support member 2 is vertically fixedly connected to the base 1;

[0032] Multiple card slots 21 adapted to the substrate 3 are provided on both sides of the support member 2; one end of the substrate 3 is detachably connected to the card slot 21, and the other end of the substrate 3 is inserted into the groove 41 of the wax mold 4, and the thickness of the substrate 3 is smaller than the width of the groove 41.

[0033] In this embodiment, after the wax mold 4 is taken out of the furnace, the groove 41 of the wax mold 4 is placed on the other end of the substrate 3 on the support 2, or one end of the substrate 3 is inserted into the groove 41 of the wax mold 4, and then the other end of the substrate 3 is inserted into the slot 21, so that the wax mold 4 is naturally cooled on the wax mold base assembly. In this embodiment, a substrate with a thickness less than the width of the wax mold groove 41 is used to easily insert the wax mold groove 41, reduce the difficulty of mold insertion and avoid deformation of the wax mold, and use air natural cooling to ensure that the size shrinkage of the wax mold is stable, thereby ensuring the size accuracy of the wax mold.

[0034] Alternatively, if Figure 3As shown, the depth of the slot 21 is the thickness of the support member 2. The slot 21 runs through the slot 2 from one side to the other side, and the insertion depth of the substrate 3 can be adjusted according to the weight of the wax mold 4, thereby ensuring the stability of the base frame.

[0035] Alternatively, if Figure 1 As shown, the main body 42 of the wax mold 4 is below the substrate 3. The groove 41 of the wax mold 4 is directly placed on the other end of the substrate 3 on the support 2, so that the wax mold 4 can expand the width of the groove 41 by its own weight, thereby making it easier to insert the mold.

[0036] Optionally, the base 1, the support 2 and the base plate 3 are all made of aluminum alloy to improve the overall stability of the wax model base assembly.

[0037] Alternatively, if Figure 4 As shown, the support member 2 is vertically plugged into the base 1 to facilitate disassembly of the support member 2 and the base 1, thereby facilitating replacement of different support members 2 or bases 1 to meet the cooling requirements of wax models of various specifications.

[0038] Alternatively, if Figure 4 As shown, the thickness of the contact portion 22 of the support member 2 that contacts the base 1 is smaller than the thickness of the portion 23 of the support member 2 that does not contact the base 1 , so as to form a mortise and tenon structure and improve the supporting stability of the support member 2 .

[0039] Alternatively, if Figure 5 As shown, the other end of the substrate 3 is a semicircle 31, so as to utilize the arc guiding characteristics of the semicircle to make it easier to insert the substrate 3 into the groove 41 of the wax mold 4, thereby reducing the difficulty of mold insertion.

[0040] Alternatively, if Figure 5 As shown, the edge of the substrate 3 is provided with a smooth guiding surface 32, so that the smooth guiding surface can guide the two inner sides of the groove 41, so that the substrate 3 can be more easily inserted into the groove 41 of the wax mold 4, reducing the difficulty of mold insertion.

[0041] Alternatively, if Figure 1 The spacing between adjacent slots 21 on the same side of the support member 2 is greater than the spacing between adjacent slots 21 on both sides of the support member 2, so as to improve the space utilization of the support member 2 while ensuring that the wax models on the same side do not affect each other, thereby meeting the cooling requirements of the industrial production of wax models.

[0042] Working process of wax model base assembly: Figures 1 to 5As shown, the support member 2 is vertically plugged into the base 1, and multiple substrates 3 are inserted into the slots 21 of the support member 2; when the wax mold 4 is out of the furnace, the groove 41 of the wax mold 4 is moved along the semicircular 32 and the smooth guide surface 33 of the substrate 3, toward the direction close to the support member 2, so that the groove 41 of the wax mold 4 is sleeved on one end of the substrate 3, and the depth of the substrate 3 in the slot 21 is adjusted according to the weight of the wax mold 4, and the mold insertion is completed, and the wax mold 4 is allowed to cool naturally in the air. After the wax mold 4 is cooled, the wax mold 4 is moved away from the support member 2 to remove the wax mold 4 from the substrate, and the mold removal is completed. The difficulty of mold insertion and mold removal is reduced, and the size shrinkage of the wax mold is guaranteed to be stable, and the deformation of the wax mold is avoided, thereby ensuring the size accuracy of the wax mold.
