Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a plastic bottle cap injection mold. Background Technology

[0002] Plastic bottle cap injection molds are specialized equipment used to produce plastic bottle caps. Injection molds are key to manufacturing various plastic products. By injecting molten plastic slurry into the mold cavity, and then demolding it after cooling, products of the desired shape and size are obtained.

[0003] According to the utility model patent with patent authorization announcement number CN212826574U, a plastic bottle cap injection mold includes a flow guide cavity and an anti-slip pad. The top of the anti-slip pad is fixedly connected to a sealing structure. The top of the anti-slip pad is provided with a lower mold. The top of the lower mold is movably connected to an upper mold. An injection port is provided at the middle position of the top of the upper mold.

[0004] However, the unstable placement of plastic bottle cap injection molds during use can easily lead to uneven molding of the workpiece, and plastic bottle cap injection molds are easy to demold during use. Summary of the Invention

[0005] The purpose of this utility model is to provide a plastic bottle cap injection mold that solves the problem that unstable placement of the plastic bottle cap injection mold during use can easily lead to uneven workpiece molding, and that the plastic bottle cap injection mold is easy to demold during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic bottle cap injection mold, comprising a mold, wherein two ejector rods are slidably connected inside the mold and are symmetrically distributed on the mold, wherein a top plate is fixedly connected to the lower end of the ejector rod, a spring is provided on the outer side of the ejector rod, and an adjustment mechanism is provided on the mold.

[0007] Preferably, one end of the spring contacts the mold, and the other end of the spring contacts the top plate. Through the design of the spring, the ejector rod can be driven to reset.

[0008] Preferably, a guide rod is fixedly connected to the upper end of the top plate, and the guide rod is slidably connected to the mold. Through the design of the guide rod, the top plate can be guided.

[0009] Preferably, the adjusting mechanism includes a threaded rod, which is slidably connected inside the mold. A support base is fixedly connected to the lower end of the threaded rod, and a connecting rod is fixedly connected to the upper end of the support base. A connecting plate is fixedly connected to the upper end of the connecting rod. A limit block is rotatably connected inside the mold, and the limit block is movably connected to the threaded rod. A limit sleeve is fixedly connected to the lower end of the limit block. By rotating the limit sleeve, the limit sleeve and the threaded rod undergo threaded movement, causing the threaded rod to move within the limit sleeve. This allows the threaded rod to move the support base, thereby adjusting the position of the support base and adjusting the support point of the mold, thus ensuring the mold remains stable.

[0010] Preferably, the connecting plate is slidably connected to the mold and fixedly connected to the threaded rod. The design of the connecting plate can guide the threaded rod.

[0011] Preferably, a protrusion is fixedly connected to the outer side of the limiting block, and the protrusion is rotatably connected to the mold. Through the design of the protrusion, the limiting block can play a limiting role.

[0012] Preferably, the limiting sleeve contacts the mold, and the limiting sleeve is connected to the threaded rod by a thread. Through the design of the limiting sleeve, the support point of the mold can be adjusted.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a limiting sleeve, a threaded rod, and a support base, allows the limiting sleeve and the threaded rod to move threadedly when rotated, so that the position of the support base can be adjusted. This, in turn, adjusts the support point of the mold, thereby ensuring the stability of the mold placement. This solves the problem that unstable placement of plastic bottle cap injection molds during use can easily lead to uneven workpiece molding.

[0015] 2. This utility model, by setting up components such as a top rod, a top plate, and a spring, allows the top plate to be moved so that it drives the top rod to lift the workpiece formed in the mold, thus facilitating demolding and solving the problem of easy demolding when using plastic bottle cap injection molds.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A plastic bottle cap injection mold includes a mold 1. Two ejector rods 2 are slidably connected inside the mold 1 and are symmetrically distributed on the mold 1. A top plate 21 is fixedly connected to the lower end of each ejector rod 2. A spring 22 is provided on the outer side of each ejector rod 2. One end of the spring 22 contacts the mold 1, and the other end contacts the top plate 21. The spring 22 can drive the ejector rod 2 to reset. A guide rod 23 is fixedly connected to the upper end of the top plate 21 and is slidably connected to the mold 1. The guide rod 23 guides the top plate 21. An adjustment mechanism 3 is provided on the mold 1.

[0024] Please see Figure 2-5 The adjusting mechanism 3 includes a threaded rod 31. The threaded rod 31 is slidably connected inside the mold 1. The lower end of the threaded rod 31 is fixedly connected to a support base 32. The upper end of the support base 32 is fixedly connected to a connecting rod 33. The upper end of the connecting rod 33 is fixedly connected to a connecting plate 34. The connecting plate 34 is slidably connected to the mold 1 and fixedly connected to the threaded rod 31. Through the design of the connecting plate 34, the threaded rod 31 can be guided. The mold 1 is rotatably connected to a limit block 35. The limit block 35 is movably connected to the threaded rod 31.

[0025] Please see Figure 2-5A protrusion 36 is fixedly connected to the outer side of the limiting block 35. The protrusion 36 is rotatably connected to the mold 1. The protrusion 36 can limit the limiting block 35. A limiting sleeve 37 is fixedly connected to the lower end of the limiting block 35. The limiting sleeve 37 contacts the mold 1. The limiting sleeve 37 is threadedly connected to the threaded rod 31. The limiting sleeve 37 can adjust the support point of the mold 1. By rotating the limiting sleeve 37, the limiting sleeve 37 and the threaded rod 31 will move threadedly, so that the threaded rod 31 can move within the limiting sleeve 37. This will cause the threaded rod 31 to drive the support base 32 to move, thereby adjusting the position of the support base 32 and adjusting the support point of the mold 1, thus keeping the mold 1 stable.

[0026] Please see Figure 2-5 ,

[0027] The specific implementation process of this utility model is as follows: When in use, by rotating the limiting sleeve 37, the limiting sleeve 37 and the threaded rod 31 will undergo threaded movement, thereby causing the threaded rod 31 to move within the limiting sleeve 37. This allows the threaded rod 31 to drive the support base 32 to move, thereby adjusting the position of the support base 32 and adjusting the support point of the mold 1, thus ensuring the stability of the mold 1.

[0028] By moving the top plate 21 closer to the mold 1, the top plate 21 drives the ejector rod 2 to move, causing the top plate 21 to compress the spring 22 and the ejector rod 2 to slide inside the mold 1. This allows the ejector rod 2 to lift the workpiece formed inside the mold 1, making it easier to demold the mold 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
