Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically to a molding mold for rubber-wrapped hardware. Background Art

[0002] The molding molds for rubber-coated hardware are mainly used to produce composite components that tightly wrap rubber materials on the outer layer of hardware. They are often used in handle products that require shockproofing, insulation, or enhanced grip comfort. Such molds need to precisely match the shape and size of the hardware, and pour rubber material to evenly wrap it and firmly bond it to the hardware.

[0003] Existing rubber-coated hardware molding molds are usually divided into upper molds and lower molds. When in use, the hardware is placed inside the mold, and the rubber material is injected into the mold cavity to make it tightly connected with the hardware. Through carefully designed and manufactured rubber-coated hardware molding molds, high-quality rubber-coated hardware products can be produced efficiently and stably.

[0004] In actual use of the prior art, since the hardware is easily offset or moved due to external force when wrapped with rubber through mold injection molding, the rubber wrapped on the hardware may be offset and misaligned, affecting the appearance and function of the product. Therefore, a molding mold for rubber-wrapped hardware is proposed. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the utility model provides a forming mold for rubber-wrapped hardware, which drives the connecting plate and the upper mold to move downward through an electric push rod to be tightly connected with the lower mold and clamp the hardware in the middle. At this time, the two arc-shaped clamping plates are pressed against the outer surface of the hardware and squeeze the spring. The spring is compressed to generate a resistance force that drives the arc-shaped clamping plates to fix and clamp the hardware, and the friction between the hardware and the rubber pad is increased by the rubber pad to prevent the hardware from being offset or moved due to external force, resulting in the rubber wrapped on the hardware being offset and misaligned, affecting the appearance and function of the product, and improving the stability during processing.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A forming mold for rubber-wrapped hardware comprises a workbench, the upper surface of the workbench is fixedly connected to a lower mold, the upper surface of the lower mold is movably connected to an upper mold, the outer surface of the lower mold is provided with a fixing mechanism, and the lower surface of the workbench is provided with a vibration mechanism; the fixing mechanism comprises a positioning rod fixedly connected to the lower surface of the lower mold, both sides of the lower mold and the upper mold are fixedly connected to fixing plates, a moving rod is inserted through the inner cavity of the fixing plate, one end of the moving rod is fixedly connected to an arc-shaped clamping plate, an electric push rod is fixedly connected to the upper surface of the workbench, and the upper end of the electric push rod is fixedly connected to a connecting plate; the vibration mechanism comprises a motor fixedly connected to the lower surface of the workbench, the output shaft end of the motor is fixedly connected to a cam, a spherical impact rod is inserted through the inner cavity of the workbench, and the lower end of the spherical impact rod is fixedly connected to a connecting sleeve.

[0010] Furthermore, the lower surface of the workbench is fixedly connected with support legs, and the upper mold is fixedly connected to the connecting plate.

[0011] Furthermore, a rubber pad is fixedly connected to the inner wall of the arc-shaped clamping plate, and hardware is interspersed inside the upper mold and the lower mold, and the rubber pad abuts against the outer surface of the hardware.

[0012] Furthermore, a spring is sleeved on the outer surface of the moving rod, and two ends of the spring are respectively fixedly connected to the fixing plate and the arc-shaped clamping plate.

[0013] Furthermore, the upper surface of the lower mold is provided with a positioning hole, and the outer surface of the positioning rod is movably connected to the inner cavity of the positioning hole.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This solution uses an electric push rod to drive the connecting plate and the upper mold to move downward and tightly connect with the lower mold and clamp the hardware in the middle. At this time, the two arc-shaped clamping plates press against the outer surface of the hardware and squeeze the spring. The spring is compressed and generates a resistance force to drive the arc-shaped clamping plates to fix and clamp the hardware. The friction between the hardware and the rubber pad is increased by the rubber pad to prevent the hardware from shifting or moving due to external force, causing the rubber wrapped on the hardware to shift and misalign, affecting the appearance and function of the product, and improving the stability during processing.

[0018] (2) This solution uses a motor to drive the cam to rotate and continuously push the connecting sleeve and the spherical impact rod to perform continuous up and down reciprocating motion with the cooperation of the connecting spring. When the spherical impact rod performs continuous up and down reciprocating motion, it will continuously impact the bottom of the lower mold to cause it to vibrate continuously, thereby eliminating the bubbles trapped in the rubber material inside the lower mold and the upper mold, ensuring the density and quality of the rubber product.

[0032] Specifically, the lower surface of the workbench 1 is fixedly connected with the support legs 101, the upper mold 103 is fixedly connected with the connecting plate 211, the inner wall of the arc-shaped clamping plate 207 is fixedly connected with the rubber pad 208, the upper mold 103 and the lower mold 102 are interspersed with the hardware 202, the rubber pad 208 is in contact with the outer surface of the hardware 202, the outer surface of the moving rod 206 is sleeved with a spring 209, and the two ends of the spring 209 are respectively fixedly connected with the fixed plate 205 and the arc-shaped clamping plate 207, and the upper surface of the lower mold 102 is opened with a positioning hole 204, and the outer surface of the positioning rod 203 is movably connected with the inner cavity of the positioning hole 204;

[0033] Furthermore, the hardware 202 to be processed is placed above the arc-shaped clamping plates 207 on both sides of the lower mold 102, and then the electric push rod 210 is started to drive the connecting plate 211 and the upper mold 103 to move downward and tightly connect with the lower mold 102 and clamp the hardware 202 in the middle. At this time, the two arc-shaped clamping plates 207 are pressed against the outer surface of the hardware 202 and squeeze the spring 209. The spring 209 is compressed to generate a resistance force to drive the arc-shaped clamping plates 207 to fix and clamp the hardware 202, and the friction between the hardware 202 is increased by the rubber pad 208 to prevent the hardware from being offset or moved due to external force.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 , which is the second embodiment of the utility model, and is based on the previous embodiment. A vibration mechanism 3 is provided on the lower surface of the workbench 1, including a motor 301 fixedly connected to the lower surface of the workbench 1, a cam 302 is fixedly connected to the output shaft end of the motor 301, a spherical impact rod 303 is inserted into the inner cavity of the workbench 1, and a connecting sleeve 304 is fixedly connected to the lower end of the spherical impact rod 303;

[0036] Specifically, the outer surface of the cam 302 abuts against the inner wall of the connecting sleeve 304, the upper surface of the connecting sleeve 304 is fixedly connected with a connecting spring 305, and the upper end of the connecting spring 305 is fixedly connected to the upper surface of the workbench 1;

When performing continuous up and down reciprocating motion, the spherical impact rod 303 will continuously impact the bottom of the lower mold 103 to cause it to vibrate continuously, thereby eliminating the bubbles trapped in the rubber material inside the lower mold 102 and the upper mold 103.

At this time, the two arc-shaped clamping plates 207 are pressed against the outer surface of the hardware 202 and squeeze the spring 209. The compression of the spring 209 will generate a resistance force to drive the arc-shaped clamping plates 207 to fix and clamp the hardware 202, and increase the friction between the hardware 202 through the rubber pad 208 to prevent the hardware from being offset or moved due to external force, resulting in the rubber wrapped on the hardware.

When the upper mold 103 moves downward, it will drive the positioning rod 203 to insert into the positioning hole 204, so as to ensure that the upper mold 103 and the lower mold 102 are accurately aligned to avoid deviation affecting the molding result. Then, the melted rubber material is injected into the upper mold 103 and the lower mold 102 through the injection port 201, so that it is wrapped on the outer surface of the hardware 202 according to a specific mold shape. Then the operator starts the motor 301 to drive the cam 302 to rotate and continuously push the connecting sleeve 304 and the spherical impact rod 303 to perform continuous up and down reciprocating motion with the cooperation of the connecting spring 305. The spherical impact rod 303 will continuously impact the bottom of the lower mold 103 during the continuous up and down reciprocating motion to cause it to vibrate continuously, thereby eliminating the bubbles entrained in the rubber material inside the lower mold 102 and the upper mold 103, and ensuring the density and quality of the rubber product.
