Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a clamping structure. Background Art

[0002] Injection molds are essential tools for producing plastic products. They give plastic products shape and specifications by providing precise structural patterns for plastic injection. Injection molding is a commonly used method for mass production of plastics. The operation process is to heat and melt the plastic raw materials, and then use the injection molding machine to push them into the pre-designed mold cavity under high pressure. Then, the mold surface of the inner wall of the mold is used to solidify the plastic into the required shape.

[0003] However, in actual use of the above-mentioned equipment, the existing injection mold clamping method mainly achieves the purpose of clamping by setting multiple bolt connectors on the mold surface and fixing the mold segments together at multiple points with bolts. It is necessary to loosen and tighten the bolts multiple times, which is troublesome to operate and reduces the efficiency of the mold clamping work. In view of this, we propose an injection mold with a clamping structure. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: an injection mold with a clamping structure, comprising a mounting plate, a side wall of the mounting plate is fixedly connected to a mounting frame, a top end surface of the mounting plate is provided with a clamping assembly, and the clamping assembly includes:

[0006] Right mold, the top end surface of the mounting plate is fixedly connected with an electric push rod, the output end of the electric push rod is fixedly connected with one end of a connecting rod, the other end of the connecting rod is fixedly connected with a mounting block 1, and the end of the mounting block 1 away from the connecting rod is fixedly connected with the right mold;

[0008] A limit rod, the left side of the second mounting block is fixedly connected to the limit rod, and the side wall of the limit rod is sleeved with the first mounting block;

[0009] An abutment rod, the inner wall of the mounting frame is fixedly connected with the abutment rod, and one end of the abutment rod away from the mounting frame is fixedly connected with a contact block;

[0010] The inner bottom of the mounting frame is fixedly connected with a mounting platform, and the top end surface of the mounting platform is fixedly connected with a convex point.

[0011] Preferably, the inner bottom of the mounting frame is fixedly connected with a guide rail, the guide rail is movably connected with a sliding rod, and one end of the sliding rod away from the guide rail is fixedly connected to the bottom end surface of the second mounting block.

[0012] Preferably, the number of the protrusions is arranged in several groups, and the protrusions in the several groups are fixedly connected to the top end surface of the mounting platform at equal intervals. When the hemisphere passes over the protrusions, the second mounting block and the left mold are vibrated.

[0013] Preferably, one end of the spring abuts against the inner wall of the mounting frame, and the other end of the spring abuts against the left end surface of the second mounting block, and the elasticity of the spring pushes the second mounting block and the left mold to reset.

[0014] Preferably, a feed inlet is provided on the top end surface of the right mold, and a feed inlet is provided on the top end surface of the left mold, and molten plastic can be injected into the right mold and the left mold through the feed inlets.

[0015] Preferably, a sliding rod is fixedly connected to the bottom end surface of the mounting block 1, and the sliding rod is slidably connected to the guide rail.

[0016] Compared with the prior art, the utility model provides an injection mold with a clamping structure, which has the following beneficial effects:

[0017] 1. The injection mold with a clamping structure is provided with an electric push rod, a connecting rod, a mounting block 1, a right mold, a limiting rod, a mounting block 2, a left mold, a feed port, a spring, a telescopic rod, a contact rod, a mounting platform, a convex point, a hemisphere and a contact block. The electric push rod pushes the right mold and the left mold to be pressed tightly, and no bolt connector is required to fix the mold sections, which reduces the trouble during installation and disassembly and improves the efficiency of the mold pressing work. When the plastic is cooled and formed, the electric push rod pulls the connecting rod and the right mold to move to the right, and the spring pushes the mounting block 2 and the left mold to reset through elastic deformation. When the hemisphere passes over the convex point, it causes the vibration of the mounting block 2 and the left mold, thereby causing the plastic and the mold to form a separation trend, which is convenient for the demolding of the plastic.

[0018] 2. The injection mold with a clamping structure supports the right mold and the left mold by setting guide rails and sliding rods, providing additional support for the clamping assembly to prevent the clamping assembly from moving sideways or tilting during clamping work, ensuring uniform distribution of clamping force, thereby improving the clamping effect and working accuracy of the mold.

[0026] The electric push rod 3 pushes the connecting rod 4 to move to the left, further making the mounting block 1 5 and the right mold 6 move to the left, so that the right mold 6 fits with the left mold 9. The electric push rod 3 continues to push the right mold 6 and the left mold 9 to move to the right, so that the mounting block 2 8 abuts against the contact block 19, further compressing the spring 11, and the right mold 6 and the left mold 9 are tightly pressed.

At this time, the molten plastic is introduced into the right mold 6 and the left mold 9 through the feed port 10. When the plastic is cooled and formed, the electric push rod 3 pulls the connecting rod 4 and the right mold 6 Moving to the right, the spring 11 pushes the mounting block 2 8 and the left mold 9 to reset through elastic deformation. When the hemisphere 16 passes over the convex point 15, it causes the mounting block 2 8 and the left mold 9 to vibrate, thereby causing the plastic and the mold to separate, which facilitates the demoulding of the plastic. Furthermore, the right mold 6 and the left mold 9 are supported by the sliding rod 18, providing additional support for the clamping assembly to prevent the clamping assembly from moving sideways or tilting during the clamping work, ensuring the uniform distribution of the clamping force, thereby improving the clamping effect and working accuracy of the mold.
