[0007] A template 100 is provided with a clamping groove 110 extending in the transverse and / or longitudinal direction;

[0008] The sand box 200 includes a box body 210, a fixing frame 220, and a partition 230. The box body 210 is disposed on the mold plate 100, and the fixing frame 220 is sleeved on the outside of the box body 210. The fixing frame 220 can be detachably connected to the clamping groove 110 on the mold plate 100 by fasteners. The partition 230 is adjustablely disposed inside the box body 210 to divide the internal space of the box body 210.

[0009] Furthermore, the template 100 is also provided with a positioning pin hole 120 for positioning the housing 210.

[0010] Furthermore, a cross groove is formed on the surface of the template 100, which divides the template 100 into four equal parts and is used to position the partition 230.

[0011] Furthermore, the surface of the housing 210 is provided with first pin holes spaced circumferentially; the end face of the partition 230 is provided with a second pin hole, which can cooperate with the first pin hole to insert a pin rod, thereby fixing the partition 230 to the inside of the housing 210.

[0012] Furthermore, the partition 230 includes a transverse partition 231 and a longitudinal partition 232. The transverse partition 231 and the longitudinal partition 232 are provided with slots spaced apart along their respective length directions on their sides. The transverse partition 231 and the longitudinal partition 232 are interlocked through the slots on their respective sides.

[0013] Furthermore, the bottom side of the fixing frame 220 is provided with an outwardly extending edge, and a slot is provided on the edge. The slot can be connected and fixed by fasteners in conjunction with the clamping groove 110.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model provides a combined molding sand box. By adding an inner partition inside the sand box, the internal space of the sand box is divided. According to different casting sizes, the effective space size inside the molding sand box can be flexibly and conveniently adjusted by adjusting the position of the partition inside the sand box. The parting pattern is clamped and fixed based on the clamping groove on the molding plate. The parting pattern and the molding plate have a wider matching degree, which can meet the requirements of the molding sand box corresponding to the parting pattern and effectively control the amount of molding sand.

[0016] This utility model provides a combined template sandbox that allows for the simultaneous matching and application of "combined templates" and "combined sandboxes," avoiding the high manufacturing costs of "dedicated templates" and "dedicated sandboxes." Furthermore, it enables "one template for multiple molds" and "one template for multiple varieties," and the sandbox template can be reused repeatedly. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1 to 8 This embodiment provides a combined template sand box, including: template 100 and sand box 200.

[0030] The template 100 is provided with a plurality of clamping grooves 110 extending in the transverse and longitudinal directions. The clamping grooves 110 can be used to fix the parting pattern and the sand box 200. The template 100 is also provided with positioning pin holes 120 for the installation and positioning of the sand box 200.

[0031] The sand box 200 includes a box body 210, a fixing frame 220, and a partition 230. The box body 210 is mounted on the template 100 and can be installed and positioned through the positioning pin holes 120 on the template 100. The fixing frame 220 is sleeved on the outside of the box body 210. The bottom side of the fixing frame 220 is provided with an outwardly extending edge 221. The edge 221 is provided with a slot 222. The slot 222 can be connected and fixed with the clamping groove 110 by bolts or other fasteners, so that the fixing frame 220 and the template 100 can be detachably connected. The partition 230 is adjustablely disposed inside the box body 210 to divide the internal space of the box body 210.

[0032] In this embodiment, in order to flexibly and conveniently divide the internal space of the box 210, the partition 230 includes a horizontal partition 231 and a vertical partition 232. The top edge of the horizontal partition 231 is provided with a first slot 2311 spaced apart along its length, and the bottom edge of the vertical partition 232 is provided with a second slot 2321 spaced apart along its length. The horizontal partition 231 and the vertical partition 232 are interlocked by the first slot 2311 and the second slot 2321 on their respective sides. By selecting different first slots 2311 and second slots 2321, the relative positions of the horizontal partition 231 and the vertical partition 232 can be changed, and the internal space of the box 210 can be divided into spaces of different sizes. In addition, the number of the horizontal partition 231 and the vertical partition 232 can be designed according to actual needs to meet the requirements of different space divisions.

[0033] The side wall surface of the housing 210 is provided with first pin holes 211 spaced circumferentially; the end faces of the transverse partition 231 and the longitudinal partition 232 are provided with second pin holes 233, which can cooperate with the first pin holes 211 to insert pins and fix the transverse partition 231 and the longitudinal partition 232 to the inside of the housing 210.

[0034] In this embodiment, a cross groove 130 is also provided on the surface of the mold plate 100. The cross groove divides the mold plate 100 into four equal parts. When the sand box space required for the parting pattern is exactly one-quarter of the mold plate 100, the transverse partition 231 and the longitudinal partition 232 can be positioned by the cross groove 130.

[0035] This embodiment provides a method for using a combined plate sandbox:

[0036] Step 1: Based on the sand box size required for the production of the prototype, the internal space of the box 210 is divided into the required sand box size by adjusting the positions of the transverse partition 231 and the longitudinal partition 232 inside the box body 210.

[0037] Step 2: Install the parting pattern to be tested in the sand box space divided inside the box 210, and fix the parting pattern with bolts and other fasteners.

[0038] Step 3: Insert the pins into the first pin hole 211 and the second pin hole 233, and place the transverse partition 231 and the longitudinal partition 232 inside the housing 210.

[0039] Step 4: Pour the self-hardening resin sand into the space divided by the box 210, wait 30 minutes for the sand to solidify, then pull out the pins used to fix the transverse partition 231 and the longitudinal partition 232, and demold the sand mold, repeating the above steps.
