Description

Technical Field

[0001] This utility model relates to the field of seat mold technology, and in particular to a 3D printed sand mold for casting the upper mold of a seat mold. Background Technology

[0002] In the production process of car seat molds, the upper mold has many undercuts and its shape is too complex, making CNC machining difficult and time-consuming. This requires a better process to solve this problem. Using 3D printing casting technology can easily produce complex upper molds and improve production efficiency.

[0003] However, during the casting process, the foam model needs to be connected to the sand mold below before covering it with the mixed sand required to make the sand mold. After solidification, the foam model is removed, and a cavity is formed between the formed mixed sand and the sand mold below, which can then be poured. However, when connecting the foam model to the sand mold below, due to the lack of certain limiting and fixing, the foam model and the sand mold below are prone to displacement during installation, which affects the casting quality.

[0004] To address these issues, we provide a 3D-printed sand mold for casting the upper mold of a seat mold. Utility Model Content

[0005] The purpose of this invention is to provide a 3D printed sand mold for upper mold casting of seat molds, which solves the problem of misalignment between the foam model and the sand mold below in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a 3D printed sand mold for casting the upper mold of a seat mold, including a 3D sand mold, wherein a foam model is provided on the top surface of the 3D sand mold;

[0008] A limiting mechanism is provided below the foam model. The limiting mechanism includes two limiting plates fixedly installed on the bottom surface of the foam model, and two limiting grooves are provided on the top surface of the 3D sand mold.

[0009] A stabilizing mechanism is provided above the 3D sand mold. The stabilizing mechanism includes an L-shaped strip fixedly installed on the bottom surface of the foam model, and an L-shaped groove is provided on the top surface of the 3D sand mold.

[0010] The present invention is further configured such that the outer walls of the two limiting plates are slidably connected to the inner walls of the two limiting grooves respectively.

[0011] The present invention is further configured such that arc-shaped plate one and arc-shaped plate two are fixedly installed on the two sides of the two limiting plates respectively, and the top surfaces of the two arc-shaped plates two and the top surfaces of the two arc-shaped plates one are fixedly connected to the bottom surface of the foam model.

[0013] The present invention is further configured such that four fixing blocks are fixedly installed on the bottom surface of the foam model, and an insertion block is fixedly installed on the bottom surface of each of the four fixing blocks. The top surface of the 3D sand mold is provided with four insertion slots, and the inner walls of the four insertion slots are slidably connected to the outer walls of the four insertion blocks and the outer walls of the four fixing blocks.

[0014] The present invention is further configured such that there are two L-shaped grooves and two L-shaped strips, and the inner walls of the two L-shaped grooves are slidably connected to the outer walls of the two L-shaped strips respectively.

[0015] The present invention is further configured such that a concave strip is fixedly installed on the bottom surface of the foam model, and a concave groove is opened on the top surface of the 3D sand mold, and the outer wall of the concave strip is slidably connected to the inner wall of the concave groove.

[0031] Limiting mechanism 2 is located below foam model 101. Limiting mechanism 2 includes two limiting plates 204 fixedly installed on the bottom surface of foam model 101. Two limiting grooves 201 are formed on the top surface of 3D sand mold 1. The outer walls of the two limiting plates 204 are slidably connected to the inner walls of the two limiting grooves 201. Arc-shaped plate one 205 and arc-shaped plate two 206 are fixedly installed on the two sides of the two limiting plates 204 respectively. The top surfaces of the two arc-shaped plates two 206 and the two arc-shaped plates one 205 are fixedly connected to the bottom surface of foam model 101. The two limiting grooves 204... The inner wall of the foam model 101 is provided with arc-shaped groove 1 202 and arc-shaped groove 203 respectively. The outer walls of the two arc-shaped plates 1 205 and the two arc-shaped plates 206 are slidably connected to the inner walls of the two arc-shaped grooves 1 202 and the two arc-shaped grooves 203 respectively. Four fixing blocks 207 are fixedly installed on the bottom surface of the foam model 101. Insertion blocks 208 are fixedly installed on the bottom surface of the four fixing blocks 207 respectively.

The inner walls of the four insertion grooves 209 are slidably connected to the outer walls of the four insertion blocks 208 and the outer walls of the four fixing blocks 207.

[0032] Specifically: When the foam model 101 is connected and installed with the 3D sand mold 1, the limiting plate 204, the arc plate one 205 and the arc plate two 206 fall into the limiting groove 201, the arc groove one 202 and the arc groove two 203. Since the upper opening of the arc groove one 202 and the arc groove two 203 is larger than the lower inner wall, the arc plate one 205 and the arc plate two 206 are corrected, thereby correcting the foam model 101, making it less likely for the foam model 101 to shift from the 3D sand mold 1. The insertion block 208, the fixing block 207 and the insertion groove 209 are set to further fix the foam model 101, thereby improving the casting quality. Specific Implementation Example 2

The inner walls of the two L-shaped grooves 301 are slidably connected to the outer walls of the two L-shaped strips 302, respectively. A concave strip 303 is fixedly installed on the bottom surface of the foam model 101. A concave groove 304 is provided, and the outer wall of the concave strip 303 is slidably connected to the inner wall of the concave groove 304. An installation strip 305 is fixedly installed on the bottom surface of the foam model 101. Two fixing holes 307 are opened on the bottom surface of the foam model 101.

Two round blocks 308 are fixedly installed on the top surface of the 3D sand mold 1.

[0035] Specifically: The L-shaped groove 301 and L-shaped strip 302 are provided, with the L-shaped groove 301 limiting and fixing the L-shaped strip 302; the concave strip 303 and concave groove 304 are provided, with the concave groove 304 limiting and fixing the concave strip 303; the mounting strip 305, mounting groove 306, fixing hole 307, and round block 308 are provided, with the mounting groove 306 limiting the mounting strip 305 and the round block 308 limiting the fixing hole 307, thereby limiting the 3D sand mold 1 and the foam model 101, making the connection between the 3D sand mold 1 and the foam model 101 more stable, less prone to displacement, and improving the casting quality.

[0036] The working principle of this utility model is as follows: When connecting and installing the foam model 101 with the 3D sand mold 1, the limiting plate 204, the arc plate one 205, and the arc plate two 206 fall into the limiting groove 201, the arc groove one 202, and the arc groove two 203. Since the upper opening of the arc groove one 202 and the arc groove two 203 is larger than the lower inner wall, the arc plate one 205 and the arc plate two 206 are corrected, thereby correcting the foam model 101, making it less likely for the foam model 101 to shift from the 3D sand mold 1. The insertion block 208, the fixing block 207, and the insertion groove 209 further secure the foam model. The mold 101 is fixed, thereby improving the casting quality. At the same time, the L-shaped groove 301 limits and fixes the L-shaped strip 302. The concave strip 303 and concave groove 304 are provided, and the concave groove 304 limits and fixes the concave strip 303. The mounting strip 305, mounting groove 306, fixing hole 307 and round block 308 are provided. The mounting groove 306 limits the mounting strip 305, and the round block 308 limits the fixing hole 307, thereby limiting the 3D sand mold 1 and the foam model 101, making the 3D sand mold 1 and the foam model 101 more firmly connected and less prone to displacement, thus improving the casting quality.
