Description

Technical Field

[0001] This utility model relates to the field of thermomechanical analyzers, and in particular to a thermomechanical analyzer for injection molded products. Background Technology

[0002] A thermomechanical analyzer is an instrument used to measure the relationship between the deformation of a material and functions such as temperature and time under programmed temperature and non-vibrational load. A thermomechanical analyzer typically consists of a frame, pressure head, loading device, heating device, cooling device, and deformation measuring device.

[0003] When measuring injection molded products, the product is usually placed inside a housing, heated by a heating device, and then a loading device drives a pressure head to apply pressure to the product, thereby detecting the deformation of the product.

[0004] However, the injection molded product is heated inside the shell and pressurized by the indenter. This can cause the pressurized end of the injection molded part to stick to the indenter and the shell, which will affect the use of the thermomechanical analyzer and thus have certain defects. Utility Model Content

[0005] The purpose of this invention is to provide a thermomechanical analyzer for injection molded products to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermomechanical analyzer for injection molded products, comprising:

[0007] Support platform;

[0038] 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.

[0039] This utility model provides, for example Figure 1-3 The image shows a thermomechanical analyzer for injection molded products.

[0040] Example 1

[0041] The system includes a support platform 1, a support housing 2, a heating plate 3, a fixed bracket 4, a pressure rod 7, a mounting housing 5, and a support assembly 6. The support housing 2 is mounted on top of the support platform 1. The heating plate 3 is installed inside the support housing 2 and is used to heat the injection molded parts stored inside the support housing 2, thereby allowing the injection molded parts to be tested at a certain temperature. The fixed bracket 4 is fixedly mounted on top of the support platform 1. The outer wall of the pressure rod 7 is slidably sleeved with the support housing 2. The mounting housing 5 is fixedly mounted on the fixed bracket 4. The mounting housing 5 contains a cylinder that drives the pressure rod 7 to move, thereby causing the pressure rod 7 to descend. This allows the pressure rod 7 to pressurize the injection molded part inside the bearing housing 2. The bearing assembly 6 is located inside the bearing housing 2 and includes a first end cap 61 and a second end cap 62. The first end cap 61 and the second end cap 62 are symmetrically arranged inside the bearing housing 2. The first end cap 61 and the second end cap 62 are respectively sleeved on the ends of the injection molded part. Thus, the pressure rod 7 squeezes the first end cap 61, creating a squeezing force between the first end cap 61 and the second end cap 62, thereby squeezing the injection molded part by the first end cap 61 and the second end cap 62, and preventing the injection molded part from sticking to the pressure rod 7 and the bearing housing 2.

[0042] Furthermore, the bearing assembly 6 also includes a guide rod 63, a connecting block 64, and a locking assembly 65. The guide rod 63 is fixedly connected to the inside of the bearing housing 2. The top of the connecting block 64 has a through hole that matches the guide rod 63. The sides of the first end cap 61 and the second end cap 62 are both provided with connecting grooves. One side of the outer wall of the connecting block 64 is slidably engaged with the inner cavity of the connecting groove. The locking assembly 65 is disposed between the connecting block 64 and the second end cap 62. Under the action of the locking assembly 65, the connecting block 64 and the guide rod 63 can guide the first end cap 61 and the second end cap 62, thereby ensuring the stability of the first end cap 61 and the second end cap 62 in the extrusion of the injection molded part inside the bearing housing 2.

[0043] Example 2

[0044] Based on Embodiment 1, the locking component 65 includes a slot, a connecting rod 651, a limiting strip 652, and a handle 654. The slot is formed on the side of the first end cap 61 and the second end cap 62, and the inner cavity of the slot is connected to the inner cavity of the connecting groove. The connecting rod 651 is installed on the connecting block 64, and the outer wall of the connecting rod 651 is slidably sleeved inside the slot. The limiting strip 652 is fixedly connected to the top of the connecting rod 651 and is offset from the slot. The handle 654 is fixedly connected to the top of the limiting strip 652, and the limiting strip 652 matches the slot. Thus, when the handle 654 corresponds to the slot, the first end cap 61 or the second end cap 62 can be separated from the connecting block 64 and the limiting strip 652, so as to facilitate the disassembly and cleaning of the first end cap 61 and the second end cap 62.

[0045] Furthermore, the locking assembly 65 also includes a limiting rod 653 and a limiting groove. The limiting rod 653 is fixedly connected to the side of the limiting strip 652 facing the second end cover 62. The limiting groove is opened on the opposite side of the first end cover 61 and the second end cover 62. The outer wall of the limiting rod 653 is slidably engaged with the inner cavity of the limiting groove. The limiting rod 653 can improve the stability of the limiting strip 652 engaged with the first end cover 61 or the second end cover 62.

[0046] Furthermore, the locking assembly 65 also includes a mounting hole, a fixing collar 655, a limiting block 656, and a limiting spring 657. The mounting hole is opened on the top of the connecting block 64. The fixing collar 655 is fixedly sleeved on one end of the inner cavity of the mounting hole. The limiting block 656 is fixedly connected to the end of the connecting rod 651. The limiting spring 657 is slidably sleeved on the outside of the connecting rod 651. The limiting spring 657 is located between the fixing collar 655 and the limiting block 656. The limiting spring 657 provides an elastic force to the connecting rod 651 through the limiting block 656, thereby ensuring the stability of the bottom limiting rod 653 of the limiting strip 652 engaging with the limiting groove.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
