Description

Technical Field

[0001] The utility model relates to the technical field of thermal conductivity testing of thermal insulation mortar, in particular to a thermal insulation mortar test block manufacturing device. Background Art

[0002] The thermal conductivity test of thermal insulation mortar generally requires two thermal insulation mortar test blocks, and the size of the thermal insulation mortar test block is 300*300*30CM. A plastic molding mold for making thermal insulation mortar test blocks currently sold on the market can produce test blocks that meet the requirements.

[0003] However, this structure has the following problems: 1. The plastic molding mold is simple, and the inner wall will be worn out after long-term use, which is not conducive to demolding; 2. The plastic molding mold is an integrated injection molding, and the contact area between the frame structure and the test block is large, which is not conducive to demolding; 3. Only one test block can be made at a time, and two sets of molding molds are required to mold two test blocks. When there are many types of test blocks, it is easy to cause confusion among test blocks from different batches. Utility Model Content

[0004] The utility model aims to provide a device for making thermal insulation mortar test blocks, which facilitates demoulding and reduces wear by changing the traditional one-piece injection molding mold into a split assembly structure. Through one mold with two cavities, two test blocks can be produced at the same time.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a thermal insulation mortar test block production device including a mold frame, the mold frame including two symmetrically arranged and mutually interlocked "J"-shaped frames, a longitudinal partition plate is clamped between the two "J"-shaped frames, and the top and bottom of the longitudinal partition plate are flush with the bottom and top of the mold frame; the longitudinal partition plate divides the space inside the mold frame into two molding cavities with the same length, width and height, and the two "J"-shaped frames are locked by a locking structure.

[0006] After adopting the above structure, a longitudinal partition plate is clamped by two "X"-shaped frames, and the molding mold is changed into a split assembly structure. When demolding, the locking structure is disassembled, the two "X"-shaped frames are separated, and the longitudinal partition plate is removed, so that the contact area between the test block and the molding mold becomes smaller, thereby facilitating demolding and avoiding internal wear of the molding mold caused by violent demolding; at the same time, the molding cavity is divided into two by the longitudinal partition plate, so that two test blocks can be produced in the same batch, avoiding confusion of test blocks from different batches.

[0007] In order to increase the number of test blocks produced and prevent bad test blocks from affecting the test accuracy, a transverse partition is provided inside the mold frame. The transverse partition is vertically arranged with the longitudinal partition, and the two partitions divide the space inside the mold frame into four molding cavities with the same length, width and height.

[0008] In order to facilitate installation and ensure the dimensional stability of each test block, the transverse partition plate and the longitudinal partition plate are plugged into each other; the transverse partition plate and the mold frame are plugged into each other.

[0009] In order to facilitate placement, a bottom plate is also included. The bottom plate is located at the bottom of the mold frame and forms a closed molding cavity with the mold frame.

[0010] In order to facilitate the movement and removal of the test block, handles are arranged on opposite sides of the mold frame.

[0011] In order to ensure the docking accuracy, positioning structures are provided on the convex edges on both sides of the two "J"-shaped frames.

[0012] For easy installation, the positioning structure includes positioning posts arranged on the convex edges on both sides of any one of the "X"-shaped frames, positioning holes cooperating with the positioning posts are arranged on the convex edges on both sides of the other "X"-shaped frame, and limiting holes for the positioning posts to pass through are also arranged on the longitudinal partition plate.

[0013] In order to prevent impurities from affecting the locking, the locking structure includes a rotating structure, which includes a knob and a cam block. The knob and the cam block are detachably connected via a connecting shaft, which is rotatably mounted on any one of the X-shaped frames. A through hole for the cam block to pass through is provided on the other X-shaped frame. When the knob is rotated, the cam block is stuck on the outside of the through hole.

[0014] In order to guide the locking and facilitate the locking, an arc surface convex toward the middle is provided on the side of the cam block located on one side of the knob.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model discloses a thermal insulation mortar test block production device which solves the technical problems in the prior art that the thermal insulation mortar test block mold is difficult to demould, resulting in serious wear of the mold, and it is impossible to produce two thermal insulation mortar test blocks at the same time, resulting in confusion of the test blocks. The utility model changes the traditional one-piece injection molding mold into a split assembly structure, thereby facilitating demoulding and reducing wear. Through one mold with two cavities, two test blocks can be produced at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientations of the thermal insulation mortar test block manufacturing device of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0025] Embodiment 1:

[0026] like Figure 1 and Figure 2 As shown together, a thermal insulation mortar test block manufacturing device includes a mold frame 2. In this embodiment, the mold frame 2 is made of metal and can be made of alloy steel, so that it is wear-resistant and its service life is increased. It also includes a bottom plate 1, which is located at the bottom of the mold frame 2. When the mold frame 2 is placed on the bottom plate 1, the bottom plate 1 and the mold frame 2 form a closed molding cavity. The bottom plate 1 can be detachably fixed to the bottom of the mold frame 2, or the mold frame 2 can be directly placed flat on the bottom plate 1. Whether the two are fixed or not is not limited in this embodiment. As long as the bottom plate 1 is placed on a plane and the mold frame 2 is placed on the bottom plate 1, the two form a molding cavity with a relatively sealed bottom.

[0027] The mold frame 2 includes two symmetrically arranged and interlocked "X"-shaped frames 21, a longitudinal partition plate 22 is sandwiched between the two "X"-shaped frames 21, and the top and bottom of the longitudinal partition plate 22 are flush with the bottom and top of the mold frame 2; the longitudinal partition plate 22 divides the space inside the mold frame 2 into two molding cavities with the same length, width and height, and the two "X"-shaped frames 21 are locked by a locking structure 3.

[0028] The locking structure 3 can be a through hole 211 opened on the convex edge of both sides of the cross-shaped frame 21, by screwing a bolt into the through hole 211, tightening a nut at the end of the bolt, and locking the two cross-shaped frames 21 by the nut and the bolt, while avoiding interference, so an avoidance hole for the bolt to pass is also provided on the longitudinal partition plate 22. Because the thread structure is relatively precise, it is very easy to apply mortar on the construction site, making it difficult to unscrew.

[0029] Therefore, the locking structure 3 in this embodiment includes a rotating structure 31, and the rotating structure 31 includes a knob 311 and a cam block 312. The knob 311 and the cam block 312 are detachably connected via a connecting shaft 313. A rotating hole 32 is provided on any one of the "X"-shaped frames 21, and the connecting shaft 313 is rotatably installed in the rotating hole 32. A through hole 211 is provided on the other "X"-shaped frame 21 for the cam block 312 to pass through. In this embodiment, the cam block 312 is preferably a "X"-shaped block, and its minimum width is consistent with the connecting shaft 313. When the knob 311 is rotated, the cam block 312 is stuck on the outside of the through hole 211, thereby achieving locking. Of course, in order to avoid interference with the longitudinal partition plate 22, an intermediate hole 221 is also provided on the longitudinal partition plate 22 for the cam block 312 to pass through. The structure of the intermediate hole 221 is consistent with that of the through hole 211.

[0030] In order to reduce the difficulty of rotation, the side surface of the cam block 312 located on the side of the knob 311 is provided with an arc surface convex toward the middle. When rotation occurs, it is easier to tighten under the guidance of the arc surface.

[0031] In order to increase the docking accuracy between the two "J"-shaped frames 21, positioning structures 4 are provided on the convex edges on both sides of the two "J"-shaped frames 21. The positioning structure 4 includes positioning posts 41 provided on the convex edges on both sides of any "J"-shaped frame 21, positioning holes 42 cooperating with the positioning posts 41 are provided on the convex edges on both sides of the other "J"-shaped frame 21, and limiting holes 43 for the positioning posts 41 to pass through are also provided on the longitudinal partition plate 22.

[0032] In order to facilitate the movement and removal of the test block, handles 24 are provided on opposite sides of the mold frame 2 .

[0033] During installation: install the rotating structure 31 in the rotating hole 32 in advance, and then pass the positioning columns 41 of the two "X"-shaped frames 21 through the limiting holes 43 and the positioning holes 42 of the longitudinal partition plate 22 in turn. During the passing process, adjust the cam block 312 to pass through the middle hole 221 and the through hole 211 in turn. After the docking is completed, rotate the knob 311 to drive the cam block 312 to rotate, and the cam block 312 is stuck on the outside of the through hole 211, thereby realizing the locking of the two "X"-shaped frames 21.

[0034] Embodiment 2:

[0035] like Figure 3 and Figure 4As shown together, in order to increase the number of test blocks produced and prevent bad test blocks from affecting the test accuracy, a transverse partition plate 23 is provided inside the mold frame 2 in this embodiment. The transverse partition plate 23 is vertically arranged with the longitudinal partition plate 22, and the two divide the space inside the mold frame 2 into four molding cavities with the same length, width and height.

[0036] The transverse partition plate 23 and the longitudinal partition plate 22 are plugged into each other; the transverse partition plate 23 and the mold frame 2 are plugged into each other.

[0037] In order to facilitate the installation of the transverse partition plate 23, a buckle groove is provided between the transverse partition plate 23 and the longitudinal partition plate 22. The buckle groove can be a single-sided buckle groove 231 (such as Figure 3 and Figure 4 As shown in FIG. 2 , only a single-sided buckle groove 231 is provided on the transverse partition plate 23. However, this structure will inevitably lead to a bulge on the top thereof. When manufacturing, the volume of the bulge can be minimized to avoid uneven corners of the manufactured test block.

[0038] like Figure 5 As shown, a plug-in method can also be adopted, that is, relative buckle grooves are provided at relative positions on the transverse partition plate 23 and the longitudinal partition plate 22, and on the transverse partition plate 23 and the mold frame 2, and the flatness of the top and bottom is achieved by plugging the two relative buckle grooves.

[0039] When the transverse partition plate 23 is buckled onto the mold frame 2 and the longitudinal partition plate 22 , its bottom is flush with the bottom of the mold frame 2 .

[0040] The utility model discloses a thermal insulation mortar test block production device which solves the technical problems in the prior art that the thermal insulation mortar test block mold is difficult to demould, resulting in serious wear of the mold, and it is impossible to produce two thermal insulation mortar test blocks at the same time, resulting in confusion of the test blocks. The utility model changes the traditional one-piece injection molding mold into a split assembly structure, thereby facilitating demoulding and reducing wear. Through one mold with two cavities, two test blocks can be produced at the same time.

[0041] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
