Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to an open-type sleeve heater. Background Technology

[0002] To prevent molten plastic from solidifying inside the injection nozzle, existing injection molds typically use heating devices, primarily sleeve heaters and spring heating coils. Longer injection nozzles often have multiple sleeve heaters; when one heater fails and needs replacement, the others must be disassembled, leading to cumbersome and inefficient replacements. Another type uses a sleeve heater composed of two semicircles, which allows for replacement without disassembling other heaters, but this requires a retaining ring for secure fixing, making replacement somewhat complicated. Therefore, an open-type sleeve heater was designed, offering convenient replacement and significantly improving production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an open-type sleeve heater to address the shortcomings of the existing technology. This open-type sleeve heater has a novel design and simple structure. It is made of stainless steel, is resistant to high temperatures, and uses elastic wall connections, making it easy to replace and greatly improving production efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] An open-type sleeve heater includes a sleeve heater body. The sleeve heater body has a vertically arranged opening groove on its side end wall, and a vertically arranged connecting groove is provided on the side wall opposite to the opening groove. The sleeve heater bodies on both sides of the connecting groove are connected by an elastic wall in the connecting groove.

[0006] The body of the sleeve heater is made of stainless steel.

[0007] The upper part of the side wall surface around the casing heater body is provided with several heating wire wiring grooves.

[0008] The thickness of the elastic wall is 0.1-0.3 mm.

[0009] The beneficial effects of this utility model are as follows: The open-type sleeve heater of this utility model includes a sleeve heater body. The sleeve heater body has a vertically arranged open slot on its side wall, and a vertically arranged connecting slot is provided on the opposite side wall of the open slot. The sleeve heater bodies on both sides of the connecting slot are connected through an elastic wall within the connecting slot. This utility model utilizes the connection between the sleeve heater bodies on both sides of the connecting slot through the elastic wall within the connecting slot, allowing the sleeve heater body to be directly opened for replacement. Because the elastic wall is made of stainless steel, it has good elasticity and strong restoring properties, making replacement simple and efficient, thereby greatly improving production efficiency. Therefore, this utility model has the advantages of novel design, simple structure, stainless steel molding, high temperature resistance, easy replacement using elastic wall connection, and greatly improved production efficiency. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings, but the embodiments in the drawings do not constitute any limitation on the present invention.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] exist Figure 1 This includes: 1—Shell heater body; 11—Open slot 12—Connecting groove; 13—Elastic wall 14——Heating wire wiring channel. Detailed Implementation

[0013] The present invention will now be described in conjunction with specific embodiments.

[0014] like Figure 1 As shown, an open-type sleeve heater includes a sleeve heater body 1. The sleeve heater body 1 has a vertically arranged opening groove 11 on its side end wall, and a vertically arranged connecting groove 12 is provided on the side wall opposite to the opening groove 11. The sleeve heater bodies 1 on both sides of the connecting groove 12 are connected by an elastic wall 13 in the connecting groove 12.

[0015] As a preferred embodiment, the sleeve heater body 1 is made of stainless steel, which is resistant to high temperatures and has good elasticity.

[0016] Furthermore, several heating wire wiring grooves 14 are provided on the upper part of the side wall surface around the casing heater body 1.

[0017] In this preferred embodiment, the thickness of the elastic wall 13 is 0.1-0.3 mm.

[0018] To provide a further explanation, this utility model utilizes the connection between the sleeve heater bodies 1 on both sides of the connecting groove 12 via the elastic wall 13 within the connecting groove 12. This allows the sleeve heater bodies 1 to be directly opened for replacement. Since the elastic wall is made of stainless steel, it has good elasticity and strong reset properties, making replacement simple and efficient, thereby greatly improving production efficiency. Therefore, this utility model has the advantages of novel design, simple structure, stainless steel molding, high temperature resistance, connection using elastic walls, easy replacement, and greatly improved production efficiency.

[0019] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
