Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a mold for preventing nuts from falling off and a nut installation fixture. Background Technique

[0002] An injection mold is a tool for plastic molding. It processes and heats plastic billets through a certain technological process, and then under the action of a certain pressure, sprays out through a die head to form the required parts and products. Injection molds are widely used in modern industrial production because there are various processing forms of plastic products and there are also many types of molds.

[0003] In the existing injection mold forming process, some structural parts (such as copper nuts) are placed on the mold before mold closing, so that the structural parts are directly set on the injection molded parts during the injection process. However, during the mold closing process of the mold, the mold is prone to vibration, resulting in the falling off of the structural parts and reducing the qualified rate of injection molding. Summary of the Utility Model

[0004] To solve the technical problems in the background technique, the utility model proposes a mold for preventing nuts from falling off and a nut installation fixture.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A mold for preventing nuts from falling off, comprising an upper template, a lower template, and a runner push plate;

[0007] A cavity is formed between the upper template and the lower template. A plurality of nuts are placed on the upper template, and a shockproof block is movably arranged on the upper template. A contact rod is arranged on the runner push plate, and a pressing block is arranged on the lower module;

[0008] The upper template at least includes a mold closing state and a mold opening state. When the upper template is in the mold opening state, the shockproof block extends out of the upper template, and the contact rod abuts against the side of the shockproof block. When the upper template is in the mold closing state, the upper template is attached to the lower template, the pressing block abuts against the end of the shockproof block, and forces the shockproof block to be received into the upper template, and the contact rod is inserted into the pressing block.

[0009] Preferably, an installation groove is arranged on the upper template, the shockproof block is placed in the installation groove, and an elastic element is arranged in the installation groove. One end of the elastic element abuts against the installation groove, and the other end abuts against the shockproof block. Through the above improvement, the shockproof block partially extends out of the installation groove under the action of the elastic element, the contact rod abuts against and presses the shockproof block from the side, thereby greatly improving the stability of the upper template and avoiding vibration of the upper template during mold closing, resulting in nut falling off.

[0010] Preferably, a guide rod is inserted into the shock-absorbing block, and the lower part of the guide rod extends out. The elastic element is sleeved on the guide rod. Through the above improvement, the elastic element is sleeved on the guide rod, which improves the stability of the shock-absorbing block during the up and down sliding process.

[0011] Preferably, a limiting groove for inserting the abutting rod is formed on the extrusion block. Through the above improvement, after the mold is closed, the upper template and the lower template are attached, and the nut has been fixed by the upper template and the lower template. At this time, the vibration block is received into the upper template under the action of the extrusion block, so that the abutting rod can move towards the lower template until it is inserted into the limiting groove.

[0012] Preferably, a guide block is arranged on the upper template, and a guide groove for placing the abutting rod is formed on the guide block. Through the above improvement, during the sliding process of the abutting rod, it moves along the guide groove. The guide groove can guide and limit the abutting rod, improving the stability of the abutting rod during the sliding process.

[0013] Preferably, at least two shock-absorbing blocks are arranged on the upper template. The shock-absorbing blocks are arranged at the upper and lower ends of the upper template and are staggered. Through the above improvement, the shock-absorbing blocks are abutted from multiple positions and directions, further ensuring the stability of the upper template, preventing the nut from falling, and improving the injection molding qualification rate.

[0014] Preferably, a first extrusion inclined surface is formed on the extrusion block, and a second extrusion inclined surface is formed on the shock-absorbing block. The first extrusion inclined surface of the extrusion block moves along the second extrusion inclined surface and forces the shock-absorbing block to be received into the upper template. Through the above improvement, when the lower template and the upper template approach and close the mold, the extrusion block will move towards the shock-absorbing block. The first extrusion inclined surface on the extrusion block slides along the second extrusion inclined surface on the shock-absorbing block, gradually receiving the shock-absorbing block into the upper template. After the mold is closed, the abutting rod on the runner push plate lacks the restriction of the shock-absorbing block, enabling the runner push plate to approach the upper template for molding.

[0015] A nut installation jig includes a handheld part, a separation plate connected to the handheld part, and a mounting plate slidably arranged between the handheld part and the mounting plate;

[0016] A plurality of mounting columns are arranged on the mounting plate. A plurality of separation tubes for inserting the mounting columns are arranged on the mounting plate. The nut is sleeved on the mounting column, and the mounting column slides along the separation tube so that the nut abuts against the separation tube and forces the nut to be retained on the upper template.

[0017] Preferably, a connecting column is connected between the handheld part and the separating plate, and a return spring is sleeved on the connecting column. One end of the return spring abuts against the handheld part, and the other end abuts against the mounting plate, so that the mounting column always has a tendency to extend out of the separating tube. Through the above improvement, when it is necessary to separate the nut from the mounting tube, the mounting plate can be pulled upward to make the mounting column slide upward. The nut abuts against the separating tube and stays on the upper template, thus realizing the installation of nuts at multiple points at one time. After the installation is completed, the mounting plate extends out of the separating tube again under the action of the return spring, improving the efficiency of nut installation.

[0018] Preferably, positioning columns are further arranged on the separating plate, and positioning holes for the positioning columns to be inserted are formed on the upper template. Through the above improvement, the accuracy of nut installation is improved.

[0019] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0020] By arranging shock-proof blocks on the upper template, abutting rods on the runner push plate, and extrusion blocks on the lower module, before the mold closing is completed, the shock-proof blocks extend out of the upper template, and the abutting rods abut against the side of the shock-proof blocks, thus ensuring that the upper template will not vibrate. And when the mold closing is completed, the upper template and the lower template are attached. At this time, the nut cannot be separated. The extrusion block abuts against the end of the shock-proof block and forces the shock-proof block to be received into the upper template, so that the runner push plate can move toward the upper template, and the abutting rod is inserted into the extrusion block, thus ensuring the stability of the upper template during the injection molding process, avoiding the dropping of the nut, and improving the qualified rate and quality of the molding.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this text to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than for defining any directional or sequential limitations.

[0032] Embodiment 1

[0033] As Figures 1-6 shown, a mold for preventing the nut 5 from falling includes an upper template 1, a lower template 2, and a runner push plate 3;

[0034] Specifically, a cavity 4 is formed between the upper template 1 and the lower template 2. A plurality of nuts 5 are placed on the upper template 1, and a shock-absorbing block 6 is movably arranged on the upper template 1. An abutting rod 7 is arranged on the runner push plate 3, and an extrusion block 8 is arranged on the lower module.

[0035] Furthermore, the upper template 1 includes at least a mold closing state and a mold opening state. When the upper template 1 is in the mold opening state, the shock-absorbing block 6 extends out of the upper template 1, and the abutting rod 7 abuts against the side of the shock-absorbing block 6. When the upper template 1 is in the mold closing state, the upper template 1 is attached to the lower template 2, the extrusion block 8 abuts against the end of the shock-absorbing block 6, and forces the shock-absorbing block 6 to be received in the upper template 1, and the abutting rod 7 is inserted into the extrusion block 8.

[0036] By setting the shock-absorbing block 6 on the upper template 1, the abutting rod 7 on the runner push plate 3, and the extrusion block 8 on the lower module, before the mold closing is completed, the shock-absorbing block 6 extends out of the upper template 1, and the abutting rod 7 abuts against the side of the shock-absorbing block 6, thus ensuring that the upper template 1 will not vibrate. And when the mold closing is completed, the upper template 1 fits with the lower template 2. At this time, the nut 5 cannot be separated. The extrusion block 8 abuts against the end of the shock-absorbing block 6 and forces the shock-absorbing block 6 to be received into the upper template 1. Subsequently, the runner push plate 3 can move towards the upper template 1, so that the abutting rod 7 is inserted into the extrusion block 8, and the injection molding work is carried out, thus ensuring the stability of the upper template 1 during the injection molding process, avoiding the dropping of the nut 5, and improving the qualified rate and quality of the molding.

[0037] As Figures 1-6 shown, for a further explanation of the installation of the shock-absorbing block 6 in this embodiment, wherein, an installation groove 101 is provided on the upper template 1, the shock-absorbing block 6 is placed in the installation groove 101, and an elastic element 102 is provided in the installation groove 101. One end of the elastic element 102 abuts against the installation groove 101, and the other end abuts against the shock-absorbing block 6.

[0038] Before the mold closing is completed, the shock-absorbing block 6 partially extends out of the installation groove 101 under the action of the elastic element 102, the abutting rod 7 abuts against it from the side and squeezes the shock-absorbing block 6, thus greatly improving the stability of the upper template 1 and avoiding the vibration of the upper template 1 during the mold closing process, which may cause the nut 5 to drop.

[0039] Specifically, a first extrusion inclined surface 105 is formed on the extrusion block 8, and a second extrusion inclined surface 106 is formed on the shock-absorbing block 6. The first extrusion inclined surface 105 of the extrusion block 8 moves along the second extrusion inclined surface 106 and forces the shock-absorbing block 6 to be received into the upper template 1.

[0040] When the lower template 2 and the upper template 1 approach for mold closing, the extrusion block 8 will move towards the shock-absorbing block 6. The first extrusion inclined surface 105 on the extrusion block 8 slides along the second extrusion inclined surface 106 on the shock-absorbing block 6, so that the shock-absorbing block 6 is gradually received into the upper template 1. After the mold closing is completed, the abutting rod 7 on the runner push plate 3 lacks the restriction of the shock-absorbing block 6, so that the runner push plate 3 can move closer to the upper template 1 for molding

[0041] As a further improvement, a guide rod 104 is inserted into the shock-absorbing block 6, and the lower part of the guide rod 104 extends out. The elastic element 102 is sleeved on the guide rod 104. The elastic element 102 is sleeved on the guide rod 104, which improves the stability of the shock-absorbing block 6 during the up and down sliding process.

[0042] As Figures 1-6As shown in the figure, a further explanation of the implementation of the abutting rod 7 in this embodiment. Among them, a guiding block 109 is provided on the upper template 1, and a guiding groove 110 for inserting the abutting rod 7 is formed on the guiding block 109. During the sliding process of the abutting rod 7, it moves along the guiding groove 110. The guiding groove 110 can guide and limit the abutting rod 7, improving the stability of the abutting rod 7 during the sliding process.

[0043] Furthermore, an installation convex portion 107 is formed on the abutting rod 7, and a positioning installation groove 108 for inserting the installation convex portion 107 is formed on the runner push plate 3, ensuring the reliability and stability of the installation of the abutting rod 7.

[0044] In addition, a limiting groove 103 for inserting the abutting rod 7 is formed on the extrusion block 8. After the mold is closed, the upper template 1 and the lower template 2 are fitted together, and the nut 5 has been fixed by the upper template 1 and the lower template 2. At this time, the vibration block is received into the upper template 1 under the action of the extrusion block 8, so that the abutting rod 7 can move towards the lower template 2 until it is inserted into the limiting groove 103.

[0045] Preferably, at least two shock-absorbing blocks 6 are provided on the upper template 1. The shock-absorbing blocks 6 are arranged at the upper and lower ends of the upper template 1 and are staggered. The shock-absorbing blocks 6 are abutted from multiple positions and directions, further ensuring the stability of the upper template 1, preventing the nut 5 from falling, and improving the injection molding qualification rate.

[0046] During the entire molding process, first place the nut 5 on the upper template 1. At this time, the shock-absorbing blocks 6 protrude from the upper template 1, and the abutting rod 7 on the runner push plate 3 abuts the shock-absorbing blocks 6 from the side, thus improving the upper template 1 from vibrating and preventing the nut 5 from falling. As the upper template 1 and the lower template 2 are fitted together for mold closing, the extrusion block 8 on the lower template 2 abuts against the end of the shock-absorbing block 6 and forces the shock-absorbing block 6 to be received into the upper template 1. Since the shock-absorbing block 6 is received into the upper template 1 and cannot block the movement of the abutting rod 7, the runner push plate 3 can move towards the upper template 1, and the abutting rod 7 is inserted into the extrusion block 8. The runner push plate 3 is fitted to the upper template 1, thereby performing the injection molding work. And during the entire injection molding process, it is ensured that the upper template 1 does not vibrate and cause the nut 5 to fall, greatly improving the molding qualification rate and quality.

[0047] Embodiment Two

[0048] As Figure 3 、 Figure 7 、 Figure 8 shown, a nut 5 installation jig includes a handheld portion 201, a separation plate 202 connected to the handheld portion 201, and an installation plate 203 slidably disposed between the handheld portion 201 and the installation plate 203.

[0049] Specifically, a plurality of mounting posts 204 are provided on the mounting plate 203, and a plurality of separation tubes 205 for the mounting posts 204 to be inserted into are provided on the mounting plate 203. The nut 5 is sleeved on the mounting post 204, and the mounting post 204 slides along the separation tube 205 so that the nut 5 abuts against the separation tube 205 and forces the nut 5 to be retained on the upper template 1.

[0050] During the installation process of the nut 5, first place a plurality of nuts 5 on the mounting posts 204 respectively, then insert the mounting posts 204 into the designated positions on the upper template 1, and then pull the mounting plate 203. The mounting posts 204 slide along the separation tubes 205 so that the nuts 5 abut against the separation tubes 205 and force the nuts 5 to be retained on the upper template 1, thereby realizing the installation of a plurality of nuts 5 at multiple points at one time and greatly improving the convenience of nut 5 installation.

[0051] Furthermore, a connecting post 206 is connected between the hand-held part 201 and the separation plate 202, and a return spring 207 is sleeved on the connecting post 206. One end of the return spring 207 abuts against the hand-held part 201, and the other end abuts against the mounting plate 203 so that the mounting post 204 always has a tendency to extend out of the separation tube 205.

[0052] When it is necessary to separate the nut 5 from the mounting tube, the mounting plate 203 can be pulled upward to make the mounting post 204 slide upward. The nut 5 abuts against the separation tube 205 and is retained on the upper template 1, thereby realizing the installation of a plurality of nuts 5 at multiple points at one time. After the installation is completed, the mounting plate 203 extends out of the separation tube 205 again under the action of the return spring 207, improving the installation efficiency of the nut 5.

[0053] Preferably, a positioning post 208 is further provided on the separation plate 202, and a positioning hole 209 for the positioning post 208 to be inserted into is formed on the upper template 1, improving the accuracy and convenience of nut 5 installation.

[0054] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
