Technical Field

[0001] This utility model belongs to the field of mold design technology, and in particular relates to the injection molding production mold for the lower trim strip of the rear bumper of automobiles. Background Technology

[0002] The injection molding mold for the lower trim strip of a car's rear bumper is a mold used to produce the trim strip below the rear bumper of a car. This trim strip is usually used to enhance the aesthetics of the car's appearance and has both decorative and protective functions.

[0003] The injection molding production mold for the lower trim strip of the rear bumper of a car usually requires the upper mold and the lower mold to be combined for injection molding. At this time, there may be gaps at the connection between the two molds, which can cause external air, impurities or moisture to enter the mold cavity. Therefore, we have proposed an injection molding production mold for the lower trim strip of the rear bumper of a car. Utility Model Content

[0004] The purpose of this utility model is to provide an injection molding production mold for the lower trim strip of a car rear bumper. By pushing the sealing strip with the lower mold, the sealing strip causes the slide to squeeze the spring. Then, the rebound of the spring causes the sealing strip to fit tightly against the connection, thus solving the problem of good sealing at the connection between the upper mold and the lower mold.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an injection molding production mold for a rear bumper trim strip of an automobile, including a support frame, a lower mold slidably connected to the outer surface of the support frame, an upper mold slidably connected to the top of the lower mold, a sealing mechanism provided on the support frame, and a locking mechanism provided on the lower mold;

[0007] The sealing mechanism includes a top cover, with a bolt threaded onto the inner wall of the top cover; an injection port is provided inside the upper mold, with a plug inserted into the inner wall of the injection port; a connecting frame is fixedly connected to the outer surface of the support frame; a slide bar is slidably connected to the inner wall of the connecting frame; a sealing strip is fixedly connected to one side of the slide bar that is close to each other; a slide groove is provided inside the slide bar; a limit rod is slidably connected to the inner wall of the slide groove; and a spring is fixedly connected to the inner wall of the connecting frame.

[0008] Furthermore, the bottom of the top cover is slidably connected to the top of the support frame, the bottom of the top cover is in contact with the top of the upper mold, a total of several bolts are provided, the outer surface of the bolt is threaded to the inner wall of the support frame, the top of the block is fixedly connected to the bottom of the top cover, and two connecting frames are provided.

[0009] Furthermore, the outer surface of the sealing strip contacts the outer surface of the upper mold, two slide grooves are provided in total, the end of the limiting rod away from the sealing strip is fixedly connected to the inner wall of the connecting frame, two springs are provided in total, the end of spring one near the lower mold is fixedly connected to the outer surface of the slide strip, and the inner side of spring one is sleeved with the outer surface of the limiting rod.

[0010] Furthermore, the locking mechanism includes a connecting block fixedly connected to the outer surface of the upper mold, and two connecting blocks are provided in total. A fixing block is slidably connected to the outer surface of the connecting block, and a plurality of fixing blocks are provided in total.

[0011] Furthermore, the outer surface of the fixing block is slidably connected to the outer surface of the upper mold, and the inner wall of the fixing block is threaded with a second bolt, the outer surface of the second bolt being threadedly connected to the inner wall of the connecting block.

[0012] Furthermore, a positioning frame is fixedly connected to the bottom of the fixing block, the outer surface of the positioning frame is fixedly connected to the outer surface of the lower mold, and a slot is opened inside the connecting block, with a card block inserted into the inner wall of the slot.

[0013] Furthermore, the positioning frame has a second sliding groove inside, and there are two sliding grooves in total.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a sealing strip. The lower mold pushes the sealing strip away from the upper mold, causing the sealing strip to slide within the connecting frame. Simultaneously, the sliding strip slides on the limiting rod via the sliding groove, compressing the spring. By tightly fitting the sealing strip at the connection between the lower and upper molds, a good seal is achieved between the two molds, effectively preventing external air, impurities, or moisture from entering the mold cavity and avoiding defects such as bubbles and pores during injection molding.

[0017] 2. This utility model incorporates a locking block. By aligning the connecting block on the upper mold with the two fixing blocks on the lower mold and pushing the upper mold downwards, the connecting block pushes the locking block, causing the locking block to move the moving rod away from each other. Simultaneously, the locking block also compresses the spring. By inserting the locking block into the slot, the upper mold can be positioned first and then fixed, which helps ensure that the various parts of the mold can be accurately aligned, reducing the problem of inaccurate dimensions or mold mismatch caused by installation errors.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, this utility model is an injection molding production mold for a car rear bumper trim strip, including a support frame 101, a lower mold 102 slidably connected to the outer surface of the support frame 101, an upper mold 103 slidably connected to the top of the lower mold 102, a sealing mechanism 2 provided on the support frame 101, and a locking mechanism 3 provided on the lower mold 102. This device seals the lower mold 102 and the upper mold 103 through the sealing mechanism 2, and then locks the lower mold 102 and the upper mold 103 together through the locking mechanism 3 to prevent defects such as bubbles and pores from occurring during the injection molding process.

[0030] The sealing mechanism 2 includes a top cover 201, with a bolt 202 threadedly connected to the inner wall of the top cover 201. An injection port 204 is provided inside the upper mold 103, and a plug 203 is inserted into the inner wall of the injection port 204. The bolt 202 can be tightened into the top cover 201 and the support frame 101. At this time, the top cover 201 fixes the position of the upper mold 103, preventing the upper mold 103 from moving within the device during injection molding. A connecting frame 205 is fixedly connected to the outer surface of the support frame 101, and a sliding strip 206 is slidably connected to the inner wall of the connecting frame 205. A sealing strip 20 is fixedly connected to one side of the sliding strips 206 that is close to each other. 7. A groove 208 is provided inside the slide bar 206. The sealing strip 207 seals the connection between the lower mold 102 and the upper mold 103 to prevent air from entering the injection cavity through the gap at the connection and affecting the injection molding result. A limit rod 209 is slidably connected to the inner wall of the groove 208. A spring 210 is fixedly connected to the inner wall of the connecting frame 205. The bottom of the top cover 201 is slidably connected to the top of the support frame 101. The bottom of the top cover 201 contacts the top of the upper mold 103. When the sealing strip 207 is squeezed, it will drive the slide bar 206 to slide in the connecting frame 205. At this time, the slide bar 206 squeezes the spring 210. The spring 210 is pressed, and its rebound can tightly fit the sealing strip 207 against the connection. Several bolts 202 are provided, and the outer surface of the bolts 202 is threaded to the inner wall of the support frame 101. The top of the plug 203 is fixedly connected to the bottom of the top cover 201. Two connecting frames 205 are provided. The plug 203 can be inserted into the injection port 204, so that the injection port 204 can be sealed after injection, further preventing air from entering. The outer surface of the sealing strip 207 is in contact with the outer surface of the upper mold 103. Two slides 208 are provided. The end of the limit rod 209 away from the sealing strip 207 is connected to the connecting frame. The inner wall of the 205 is fixedly connected, and the limiting rod 209 restricts the movement of the slide bar 206, so that the slide bar 206 can only slide along the limiting rod 209, preventing the slide bar 206 from detaching from the connecting frame 205. There are two springs 210. The end of the spring 210 near the lower mold 102 is fixedly connected to the outer surface of the slide bar 206. The inner side of the spring 210 is sleeved with the outer surface of the limiting rod 209. The limiting rod 209 restricts the movement trajectory of the spring 210, preventing the spring 210 from tilting or deviating during movement, and ensuring that the sealing strip 207 can stably seal the connection.

[0031] The locking mechanism 3 includes two connecting blocks 301 fixedly connected to the outer surface of the upper mold 103. Several fixing blocks 302 are slidably connected to the outer surface of each connecting block 301. The connecting blocks 301, which can slide between the fixing blocks 302, restrict the movement trajectory of the upper mold 103, preventing improper engagement between the upper mold 103 and the lower mold 102, and ensuring that the sealing strip 207 can function as a seal. The outer surface of the fixing block 302 is slidably connected to the outer surface of the upper mold 103. Bolts 303 are threadedly connected to the inner wall of the fixing block 302. The surface is threaded to the inner wall of the connecting block 301, and the bolt 303 can be tightened into the connecting block 301 and the fixing block 302. At this time, the bolt 303 fixes the connecting block 301, thus completing the fixation of the upper mold 103. The bottom of the fixing block 302 is fixedly connected to the positioning frame 304, and the outer surface of the positioning frame 304 is fixedly connected to the outer surface of the lower mold 102. The connecting block 301 has a slot 305 inside, and a locking block 306 is inserted into the inner wall of the slot 305. The locking block 306 will be locked in the slot 305. At this time, the locking block 306 performs preliminary positioning of the upper mold 103, which facilitates the subsequent fixation of the upper mold 103.

[0032] The positioning frame 304 has two sliding grooves 307 inside. A moving rod 308 is slidably connected to the inner wall of the sliding groove 307. The end of the moving rod 308 near the lower mold 102 is fixedly connected to the outer surface of the locking block 306. The moving rod 308 restricts the movement trajectory of the locking block 306, so that the locking block 306 can only move along the path of the moving rod 308, preventing the locking block 306 from detaching from the device. A spring 309 is fixedly connected to the outer surface of the locking block 306. Two springs 309 are provided. The end of the spring 309 away from the locking block 306 is fixedly connected to the inner wall of the positioning frame 304. The inner side of the spring 309 is sleeved with the outer surface of the moving rod 308. The moving rod 308 restricts the movement trajectory of the spring 309, preventing the spring 309 from tilting or shifting during movement, ensuring that the locking block 306 can be locked in the locking groove 305.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, firstly, the lower mold 102 is placed between the two sealing strips 207. At this time, the lower mold 102 will push the sealing strips 207 in a direction away from each other. The sealing strips 207 will then drive the slide bar 206 to slide within the connecting frame 205. Simultaneously, the slide bar 206 will also slide on the limiting rod 209 through the sliding groove 208. At this time, the slide bar 206 will also compress the spring 210, giving the spring 210 a certain rebound ability, thus achieving a good seal between the two molds. This effectively prevents external air, impurities, or moisture from entering the mold cavity, avoiding defects such as bubbles and pores during injection molding. Then, the connecting block 301 on the upper mold 103 is aligned with the two fixing blocks 302 on the lower mold 102, and the upper mold 103 is pushed downwards. At this time, the connecting block 301 will push the locking block 306, causing the locking block 306 to drive the moving rod 308 to move away from each other. Simultaneously, the locking block 306 will also compress the spring 210, giving the spring 210 a certain rebound ability. This achieves a good seal between the two molds, effectively preventing external air, impurities, or moisture from entering the mold cavity and avoiding defects such as bubbles and pores during injection molding. Then, the connecting block 301 on the upper mold 103 is aligned with the two fixing blocks 302 on the lower mold 102, and the upper mold 103 is pushed downwards. At this time, the connecting block 301 will push the locking block 306, causing the locking block 306 to drive the moving rod 308 to move away from each other. When spring 2 (309) compresses, and the upper mold 103 contacts the lower mold 102, spring 2 (309) will rebound, locking the locking block 306 into the slot 305 on the connecting block 301. At this time, the upper mold 103 is initially positioned, achieving the goal of positioning the upper mold 103 before fixing it. This helps ensure that the various parts of the mold can be accurately aligned, reducing dimensional inaccuracies or mold mismatch problems caused by installation errors. Then, bolt 2 (303) is tightened onto the connecting block 301. 01 and the fixing block 302 are used to fix the upper mold 103. At this time, the sealing strip 207 will be tightly attached to the connection between the lower mold 102 and the upper mold 103 to seal. Then, the injection material is injected between the lower mold 102 and the upper mold 103 through the injection port 204. Then, the top cover 201 is placed on the support frame 101. At this time, the plug 203 will be inserted into the injection port 204. Then, the bolt 202 is tightened in the top cover 201 and the support frame 101 to fix the top cover 201.
