[0022] It is understandable that, referring to Figures 1 to 3 ,as well as Figure 8 The injection molding material property testing mold of the present invention comprises a molding mechanism 100 and an adjusting mechanism 200. The molding mechanism 100 comprises a front mold core 110 and a rear mold core 120. The front mold core 110 can abut against the rear mold core 120. The rear mold core 120 is slidably connected with an adjusting block 121. The adjusting block 121 can move toward or away from the front mold core 110. The front mold core 110, the rear mold core 120 and the adjusting block 121 surround a mold cavity 130. The mold cavity 130 is used to mold a test piece 310. The adjusting mechanism 200 comprises a mold cavity 130. It includes a backing plate 210, a threaded sleeve 220, a screw 230 and a slider 240. The backing plate 210 is arranged on the side of the rear mold core 120 away from the front mold core 110. The threaded sleeve 220 is fixedly connected to the backing plate 210. The screw 230 and the threaded sleeve 220 are threadedly connected. The slider 240 is slidably connected to the backing plate 210. The screw 230 is connected to the slider 240. The slider 240 is inclinedly provided with a guide groove 241. The adjustment block 121 is fixedly connected to the guide block 122, and the guide block 122 is slidably connected to the guide groove 241.

[0023] The front mold core 110 can abut against the rear mold core 120 , and the adjustment block 121 is slidably connected to the rear mold core 120 . The front mold core 110 , the rear mold core 120 and the adjustment block 121 cooperate to form a mold cavity 130 , so that the test piece 310 can be formed in the mold cavity 130 . The pad 210 is arranged on the side of the rear mold core 120 away from the front mold core 110, the threaded sleeve 220 is fixedly connected to the pad 210, the slider 240 is slidably connected to the pad 210, the screw 230 is inserted into the threaded sleeve 220, and the screw 230 and the threaded sleeve 220 are threadedly connected, the guide block 122 is fixedly connected to the adjusting block 121, and the guide block 122 is slidably connected to the guide groove 241. By setting the guide groove 241 as an inclined arrangement, the screw 230 is driven to rotate in the threaded sleeve 220 so that the screw 230 can move axially, so that the screw 230 can drive the slider 240 to slide on the pad 210, so that the slider 240 can drive the adjusting block 121 to slide in the rear mold core 120, so that the size of the mold cavity 130 can be conveniently adjusted, the thickness of the test piece 310 can be flexibly adjusted, and the parameters of the injection molding material can be obtained, thereby avoiding repeated mold trials during mold development, reducing development costs, and improving production efficiency.

[0024] It should be noted that the cross-sectional shape of the slider 240 is a triangle, and the screw 230 and the slider 240 are rotatably connected, so that when the driving screw 230 rotates in the threaded sleeve 220, the screw 230 can move along the axial direction of the threaded sleeve 220, so that the screw 230 can drive the slider 240 to slide on the pad 210, and the guide block 122 is slidably connected to the guide groove 241, so that the slider 240 can push the adjustment block 121 to slide in the rear mold core 120 to adjust the distance between the front mold core 110 and the adjustment block 121, so that the thickness of the mold cavity 130 can be easily adjusted, and the injection thickness of the test piece 310 can be quickly adjusted, so as to facilitate the acquisition of parameters such as the shrinkage rate, deformation trend, and shrinkage mark of the injection molding material, instead of repeated mold trials, speeding up the development efficiency of the mold and reducing the development cost.

[0025] It is understandable that, referring to Figure 2 , Figure 3 and Figure 8The adjustment mechanism 200 also includes a stop sleeve 250 and a locking block 260. The stop sleeve 250 is sleeved on the screw 230, and the stop sleeve 250 is rotatably connected to the backing plate 210. The stop sleeve 250 is circumferentially provided with a plurality of first tooth blocks 251. The backing plate 210 is threadedly connected with a locking screw 211. The locking block 260 is slidably connected to the locking screw 211. The locking block 260 is circumferentially provided with a plurality of second tooth blocks 261. The first tooth block 251 can engage with the second tooth block 261. The anti-rotation sleeve 250 is sleeved on the screw 230 and is rotatably connected to the pad 210, and a plurality of first tooth blocks 251 are arranged along the circumference so that the anti-rotation sleeve 250 can rotate synchronously with the screw 230. A locking screw 211 is threadedly connected to the pad 210, and the locking block 260 is slidably connected to the locking screw 211 and a plurality of second tooth blocks 261 are arranged along the circumference. The locking block 260 can slide along the axial direction of the locking screw 211 so that the second tooth block 261 can engage or disengage with the first tooth block 251, thereby facilitating locking or unlocking the position of the screw 230, thereby improving the position stability of the slider 240, avoiding the position shaking of the adjustment block 121, and improving the molding stability of the test piece 310.

[0026] Among them, the pad 210 is provided with a slide groove, and the locking screw 211 is threadedly connected to the slide groove. The shape of the slide groove matches the shape of the locking block 260. The locking block 260 is set to slide on the locking screw 211 so that the locking block 260 can slide into or out of the slide groove. When the locking block 260 is located in the slide groove, the position of the locking block 260 in the locking screw 211 can be fixed to prevent the locking block 260 from rotating in the locking screw 211, and the first tooth block 251 and the second tooth block 261 can be engaged, so as to facilitate the position of the locking screw 211 and prevent the slider 240 from retreating due to the injection pressure, so that the size of the mold cavity 130 is accurate, the molding stability of the test piece 310 is improved, and the testing efficiency and the success rate of mold development are improved.

[0027] In addition, when the screw rod 230 and the anti-rotation sleeve 250 rotate synchronously, the screw rod 230 can slide along the axial direction of the anti-rotation sleeve 250 , so that the screw rod 230 can drive the slider 240 to slide on the pad 210 .

[0028] Specifically, refer to Figure 2 and Figure 3, the side wall of the screw 230 is provided with at least one plane 231, and the plane 231 matches the inner side wall of the anti-rotation sleeve 250. By setting the plane 231 to match the inner side wall of the anti-rotation sleeve 250, the screw 230 can rotate smoothly and synchronously with the anti-rotation sleeve 250, and the screw 230 can slide along the axial direction of the anti-rotation sleeve 250, thereby improving the movement stability of the screw 230. By setting the plane 231, the contact area between the screw 230 and the anti-rotation sleeve 250 can be increased, and the plane 231 matches the inner side wall of the anti-rotation sleeve 250, so that the screw 230 can rotate more smoothly when subjected to a rotational force, reducing the self-rotation deviation phenomenon caused by uneven friction or unbalanced force, improving the overall stability and reliability of the adjustment mechanism 200, and realizing precise adjustment of the size of the mold cavity 130.

[0029] It should be noted that the number of the planes 231 is set to be multiple, and the multiple planes 231 are evenly arranged along the circumference of the screw 230, so that the screw 230 can be stably stressed when rotating, reducing the wear of the screw 230 and extending the service life.

[0030] Specifically, refer to Figure 2 and Figure 3 The backing plate 210 is fixedly connected with a fixing block 212, and the first tooth block 251 is located between the backing plate 210 and the fixing block 212. By fixing the fixing block 212 on the backing plate 210 and arranging the first tooth block 251 between the backing plate 210 and the fixing block 212, the connection stability between the anti-rotation sleeve 250 and the backing plate 210 is enhanced, so that the position of the anti-rotation sleeve 250 can be kept stable, the position deviation of the anti-rotation sleeve 250 is avoided, and the anti-rotation sleeve 250 is prevented from being loosened or deviated in the axial direction due to uneven force or vibration during rotation and adjustment, so that the first tooth block 251 and the second tooth block 261 can be stably engaged or separated, thereby improving the reliability of the adjustment mechanism 200.

[0031] It is understandable that, referring to Figure 2 and Figure 3 The shape of the guide block 122 is set to be T-shaped, and the guide block 122 matches the shape of the guide groove 241. By setting the shape of the guide block 122 to be T-shaped and matching the shape of the guide groove 241, the stability and guidance of the guide block 122 in the guide groove 241 are enhanced. The T-shaped guide block 122 has a larger contact area, which can improve the sliding stability of the guide block 122 on the slider 240, and is not prone to offset or jamming, thereby improving the accuracy and reliability of the adjustment mechanism 200 when adjusting the size of the mold cavity 130, and helping to improve the stability and durability of the mold during use.

[0032] It is understandable that, referring to Figure 3 , Figure 6 and Figure 8A plurality of exhaust grooves 123 are provided on one side of the rear mold core 120 close to the front mold core 110, the depths of the plurality of exhaust grooves 123 gradually increase, and the plurality of exhaust grooves 123 are all connected to the mold cavity 130. The rear mold core 120 is provided with a plurality of exhaust grooves 123, and by setting the depths of the plurality of exhaust grooves 123 to gradually increase, it is convenient to test which depth of the exhaust grooves 123 is suitable for the injection molding material, which is convenient for mold development and improves efficiency.

[0033] It should be noted that the multiple exhaust grooves 123 are all connected to the mold cavity 130. When the injection molding material is molded into the test piece 310 in the mold cavity 130, the gas can be discharged from the exhaust grooves 123. When the depth of the exhaust grooves 123 is too small, it is easy to cause poor exhaust, resulting in molding defects of the test piece 310; when the depth of the exhaust grooves 123 is too large, it is easy to cause the injection molding material to overflow, affecting the molding size. By setting the depth of the multiple exhaust grooves 123 to gradually increase, it is convenient to test which depth of the exhaust grooves 123 is suitable for the injection molding material, so that the parameters of the injection molding material can be easily obtained, and the development efficiency of the mold can be accelerated.

[0034] Specifically, refer to Figure 3 ,as well as Figures 6 to 8 A plurality of overflow value grooves 111 are provided on one side of the front mold core 110 close to the rear mold core 120, and the plurality of overflow value grooves 111 are all located in the mold cavity 130, and the overflow value grooves 111 correspond one to one with the exhaust grooves 123. The front mold core 110 is provided with a plurality of overflow value grooves 111, and the overflow value grooves 111 correspond one to one with the exhaust grooves 123, so that the positions of the corresponding exhaust grooves 123 can be displayed on the test piece 310, and the characteristics of the injection molding material can be intuitively tested according to the actual molding quality of the test piece 310, thereby improving the convenience of the test.

[0035] It should be noted that the shape of the overflow value groove 111 corresponds to the depth information of the exhaust groove 123, so that the depth information of the corresponding exhaust groove 123 can be intuitively displayed after the test piece 310 is formed, thereby facilitating the test personnel to quickly obtain the characteristics of the injection molding material and improving the efficiency of the test.

[0036] It is understandable that, referring to Figure 4 and Figure 5The adjustment mechanism 200 also includes a positioning assembly 270, which includes a shell 271, a positioning ball 272 and a spring 273. The shell 271 is threadedly connected to the slider 240, and the positioning ball 272 is slidably connected to the shell 271. The two ends of the spring 273 respectively abut the shell 271 and the positioning ball 272. The spring 273 is used to drive the positioning ball 272 to extend out of the guide groove 241. The guide block 122 is provided with a positioning groove 124, and the positioning ball 272 can be stuck in the positioning groove 124. The shell 271 is threadedly connected to the slider 240, and the positioning ball 272 is slidably connected in the shell 271. One end of the spring 273 abuts against the shell 271, and the other end abuts against the positioning ball 272. The spring 273 can drive the positioning ball 272 to extend out of the shell 271, so that the positioning ball 272 can protrude from the guide groove 241. The guide block 122 is provided with a positioning groove 124. The positioning ball 272 can be inserted into the positioning groove 124, so that the guide block 122 can be smoothly positioned in the guide groove 241, thereby improving the convenience of testing.

[0037] It should be noted that when the positioning ball 272 is inserted into the positioning groove 124, the slider 240 is located at the initial position, which can facilitate the determination of the position of the slider 240 without disassembling the mold; when the screw 230 drives the slider 240 to slide on the pad 210, the guide block 122 can press the positioning ball 272 into the housing 271, so that the guide block 122 can slide smoothly in the guide groove 241. By setting the positioning ball 272 and the positioning groove 124 to cooperate, it is convenient to refer to the position of the slider 240, so that the test process of the test piece 310 can be conveniently adjusted, and the convenience of use is improved. Moreover, by setting the positioning ball 272 to be able to be inserted into the positioning groove 124, the rotation feel of the screw 230 can be improved, and the user experience can be improved.

[0038] It is understandable that, referring to Figure 1 , Figure 2 and Figure 8 The molding mechanism 100 further includes an ejection assembly 150, which includes a movable plate 151 and a plurality of ejector rods 152. The plurality of ejector rods 152 are fixedly connected to the movable plate 151. The movable plate 151 can move toward the direction close to the rear mold core 120 so that the ejector rods 152 can extend into the mold cavity 130. The plurality of ejector rods 152 are driven to move synchronously by the movable plate 151, so that the ejector rods 152 can extend into the rear mold core 120, and the test piece 310 can be uniformly and quickly ejected from the mold cavity 130 after cooling and solidification, thereby avoiding deformation or damage of the test piece 310, improving the test quality and efficiency, and the plurality of ejector rods 152 are arranged at intervals, so that the test piece 310 can be stably stressed, which is convenient for demolding the test piece 310 and improving efficiency.

[0039] It should be noted that when the test piece 310 is ejected from the mold, the injection molding machine can drive the front mold core 110 and the rear mold core 120 to separate, and then the injection molding machine drives the movable plate 151 to move toward the direction close to the rear mold core 120, so that the ejector rod 152 can drive the test piece 310 to be ejected from the mold cavity 130, thereby improving the ejection efficiency.

[0040] It is understandable that, referring to Figure 2 and Figure 8 The front mold core 110 and the rear mold core 120 are both provided with cooling pipes 140, which are arranged around the mold cavity 130 and are used to pass cooling water. The cooling pipes 140 are arranged around the mold cavity 130, and by passing cooling water into the cooling pipes 140, the cooling water can more evenly take away the heat generated during the injection molding process, accelerate the cooling and curing process of the test piece 310, shorten the test cycle, and improve the test efficiency.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
