Description

Technical Field

[0001] The utility model belongs to the technical field of code pullers, in particular to a hot nozzle code puller. Background Art

[0002] The hot nozzle puller is a tool specifically used to remove the hot nozzle assembly in the hot runner system. In the injection mold industry, the hot runner system is a key component that can efficiently distribute molten plastic to different parts of the mold. As the terminal part of the hot runner system, the hot nozzle is directly connected to the gate of the mold. Its installation and removal require specific tools to ensure the safety and efficiency of the operation.

[0003] Existing hot nozzle pullers have the following disadvantages: some existing pullers may be relatively complicated to operate, requiring users to spend more time and effort to use them correctly. If the design is improper, the puller may apply excessive force to the hot nozzle during use, causing damage to the equipment or injury to the operator. Some pullers may only be suitable for hot nozzles of specific types or sizes, limiting their wide application. Some pullers may be heavy or bulky, making them inconvenient to carry and use. For this reason, a hot nozzle puller is proposed. Utility Model Content

[0004] The utility model aims to provide a hot nozzle puller, aiming to solve the problems raised in the above background technology.

[0005] The utility model is implemented in this way: a hot nozzle puller, comprising:

[0006] A pull rod, the bottom of which is fixedly connected with a threaded portion;

[0007] A stopper is fixedly connected to one end of the pull rod and is used to limit the movement of the puller at a specific position;

[0008] An inertia hammer, slidably connected to the pull rod, is used to transmit the impact force;

[0009] A cross bar connected to the threaded portion at the bottom of the tie rod;

[0010] A threaded pull rod, threadedly connected to the cross bar;

[0011] The labor-saving rod is lengthened and fixed on the threaded rod;

[0012] Two symmetrically arranged pull cords are both arranged on the crossbar.

[0013] Furthermore, there is a certain interval between the inertia hammer and the stopper.

[0014] Furthermore, the inertia hammer is treated with an arc anti-slip treatment.

[0015] Furthermore, the threaded pull rod and the extended labor-saving rod form a "T"-shaped structure.

[0016] Furthermore, the main body and end portions of the pull cord are both in arc shape.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The hot nozzle puller allows intuitive control of force and direction, improving the accuracy and convenience of operation. The addition of a stopper limits the movement of the puller at a specific position, protecting the hot nozzle from excessive force and ensuring the safety of operation. The inertia hammer design provides additional impact force to assist in the pulling operation, while the arc anti-slip treatment increases the friction when in contact with the hot nozzle to prevent sliding. The arc-shaped puller design of the main part improves strength and stability, and the arc-shaped puller design at the end increases the contact area with the hot nozzle. At the same time, the quantitative design of the size and weight optimization makes it easier to carry and use. The symmetrically set puller can be adjusted left and right to adapt to hot nozzles of different sizes and types, increasing the versatility and practicality of the tool.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-3 As shown, a hot nozzle puller provided by an embodiment of the utility model includes:

[0026] The pull rod 03 has a threaded portion fixedly connected to the bottom of the pull rod 03; the user applies force to adjust the position of the hot nozzle by operating the pull rod 03. This design allows the user to intuitively control the force and direction, ensuring the accuracy and convenience of the operation.

[0027] The stopper 01 is fixedly connected to one end of the pull rod 03 and is used to limit the movement of the puller at a specific position. It physically limits the excessive movement of the puller, protects the hot nozzle from excessive force, ensures the safety of operation and prevents overload of the equipment.

[0028] The inertia hammer 02 is slidably connected to the pull rod 03. The inertia hammer 02 is used to transmit the impact force and strike the hot nozzle through the inertia force generated by its own mass to assist the pulling operation. The sliding connection between the hammer and the pull rod 03 allows the hammer to move relative to the pull rod 03 when subjected to axial force. This design allows the hammer to transmit the impact force more effectively during the pulling operation.

[0029] The crossbar 05 is connected to the threaded portion at the bottom of the pull rod 03; the crossbar 05 is a structural member connecting various components and provides stability and support.

[0030] The threaded rod 04 is threadedly connected to the crossbar 05; the nozzle can be pulled out by reversing the threaded rod 04. Due to the threaded design, the force will be more even when the operation is reversed, which helps to adjust the nozzle smoothly and accurately.

[0031] The labor-saving rod 07 is lengthened and fixedly arranged on the threaded rod 04; the user can operate it with one hand, which improves the convenience of use.

[0032] Two symmetrically arranged pullers 06 are both arranged on the crossbar 05, suitable for hot nozzles of various sizes. The puller 06 can be adjusted left and right relative to the crossbar 05 to adapt to hot nozzles of different sizes and types, increasing the versatility and practicality of the tool.

[0033] like Figure 1 As shown, as a preferred embodiment of the utility model, there is a certain interval between the inertia hammer 02 and the stopper 01. The interval design is to ensure that the inertia hammer 02 has enough moving space during operation and to protect the structure of the code puller from being damaged.

[0034] like Figure 1 As shown, as a preferred embodiment of the utility model, the inertia hammer 02 is treated with an arc anti-slip treatment to increase the friction when in contact with the hot nozzle to prevent sliding.

[0035] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, the threaded pull rod 04 and the lengthened labor-saving rod 07 form a "T"-shaped structure.

[0036] like Figure 2 and Figure 3 As shown in the figure, as a preferred embodiment of the utility model, the main body and the end of the puller 06 are both in arc shape. The design of the puller 06 with the main body in arc shape improves the strength and stability; the design of the puller 06 with the end in arc shape increases the contact area with the hot nozzle. The quantitative design means that the weight and size of the puller are optimized, making it easier to carry and use.

[0037] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
