Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and specifically relates to a template deformation test tooling. Background Art

[0002] In the injection molding machine, the injection machine template needs to clamp the mold during the product production process and needs to withstand a large clamping force. The structural strength, stress level and deformation amount have a key impact on the production of products.

[0003] At present, the strength calculation and deformation calculation of the template are mainly realized through the analysis of finite element software. The results tend to be theoretical values. During actual operation, there will be differences due to factors such as assembly errors and casting quality levels, resulting in a situation where the template theoretically meets the requirements but actually fails to meet the usage requirements. Content of the Utility Model

[0004] In order to solve the technical problems in the background art, the utility model discloses a template deformation test tooling.

[0005] The utility model provides a template deformation test tooling, which is installed between a fixed template and a moving template. The moving template and the fixed template are in a plate shape, and their strength and deformation meet the usage requirements after finite element analysis; the moving template and the fixed template are connected into a whole through fasteners;

[0006] It includes a plate frame, a push plate, a middle displacement sensor and an end displacement sensor;

[0007] The plate frame is fixedly installed on the moving template;

[0008] The push plate is installed between the plate frame and the fixed template and is fixed to the plate frame;

[0009] By closing or opening the mold, the push plate is made to abut against or move away from the fixed template;

[0010] The size of the push plate is the same as the smallest mold used in the injection molding machine; the material of the push plate is carbon tool steel;

[0011] The detection end of the middle displacement sensor abuts against the central position of the fixed template;

[0012] The detection end of the end displacement sensor abuts against the edge position of the fixed template;

[0013] By calculating the numerical difference between the middle displacement sensor and the end displacement sensor, the deformation amount of the fixed template is obtained.

[0014] The beneficial effects of the present utility model are as follows: 1. The size setting of the push plate enables the maximum pressure to be exerted on the fixed template. Therefore, when the deformation of the fixed template in the present utility model meets the usage requirements, this fixed template can meet all models of this injection molding machine; 2. The material selection of the push plate is harder, making the deformation of the fixed template more accurate during testing; 3. The push plate is installed between the plate frame and the moving template, and the detection ends of the middle displacement sensor and the end displacement sensor abut against the moving template, enabling the detection of the deformation of the moving template; 4. The present utility model has universality. By matching push plates of different sizes, template testing for different clamping models can be achieved, which can improve efficiency and reduce costs.

[0015] Further, the plate frame includes two end plates arranged in parallel; a plurality of symmetrically arranged support columns are connected between the end plates; one of the end plates is connected to the fixed template, and the other end plate is connected to the push plate.

[0016] Due to the situation where the deformation amounts at both ends of the moving template are different, if only one end displacement sensor is used, it will cause deviation in the test results. Based on this, a further improvement is that two end displacement sensors are provided and are symmetrically arranged relative to the middle displacement sensor.

[0017] Further, the middle displacement sensor and the end displacement sensor are arranged collinearly. The relative deformation amount of the fixed template in the horizontal direction can be measured.

[0018] Further, the middle displacement sensor and the end displacement sensor are arranged vertically. The relative deformation amount of the fixed template in the vertical direction can be measured.

[0019] Further, the bases of the middle displacement sensor and the end displacement sensor have magnetism and are installed on a vertically arranged vertical beam by magnetic adsorption. In this way, the position of the displacement sensor can be adjusted, and the applicable range is wider.

[0020] If the strength of the vertical beam is low, when replacing the displacement sensor, the vertical beam will deform under the action of magnetic adsorption. As a result, when changing the position of the displacement sensor, the position of the displacement sensor still needs to be adjusted, leading to reduced efficiency. Based on this, a further improvement is that the vertical beam is an H-shaped steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0026] As Figure 1 and Figure 2 shown, the present utility model discloses a template deformation test tooling, which is installed between a plate-shaped movable template 2 and a fixed template 1, and includes a plate frame 6 and a push plate 3. The material of the push plate 3 is carbon tool steel, and its hardness is greater than that of the movable template 2 and the fixed template 1. When the injection molding machine is at the maximum load, the deformation of the push plate 3 can be ignored. The plate frame 6 includes two first end plates 61 and second end plates 62 arranged in parallel; a plurality of symmetrically arranged support columns 63 are connected between the first end plate 61 and the second end plate 62. In this embodiment, the number of support columns 62 is four. The first end plate 61 is fixedly connected to the movable template 2 by bolts, and the push plate 3 is arranged between the second end plate 62 and the fixed template 1. The size of the push plate 3 is the same as the smallest mold used by the injection molding machine.

[0027] A vertically arranged vertical beam 7 is also installed on the frame of the injection molding machine. A middle displacement sensor 4 is installed on the vertical beam 7, and its detection end abuts against the center position of the fixed template; symmetrically arranged end displacement sensors 5 are installed on both sides of the middle displacement sensor 4, and their detection ends abut against the edge position of the fixed template. The bases of the middle displacement sensor 4 and the end displacement sensors 5 have magnetism and are installed on a vertically arranged vertical beam 7 by magnetic adsorption. In this way, the position of the displacement sensor can be adjusted, and the applicable range is wider. The vertical beam 7 can be, but is not limited to, an H-shaped steel, and can also be a channel steel, an I-shaped steel, etc., as long as its strength meets the requirement that when the position of the displacement sensor is changed, the vertical beam 7 will not deform. In this way, after the position of the displacement sensor is changed, it is not necessary to perform position calibration again. Among them, the middle displacement sensor 4 and the end displacement sensors 5 are arranged collinearly, and the middle displacement sensor 4 and the end displacement sensors 5 are arranged vertically. In this way, the relative deformation amounts of the fixed template 1 in the horizontal direction and the vertical direction can be measured, and the test structure accuracy is higher.

[0028] By calculating the numerical difference between the middle displacement sensor 4 and the end displacement sensors 5, the deformation amount of the fixed template 1 is obtained.

[0029] The beneficial effects of the present utility model are as follows: 1. The size setting of the push plate 3 enables the fixed template 1 to receive the maximum pressure. Therefore, when the deformation of the fixed template 1 in the present utility model meets the usage requirements, this fixed template 1 can meet all models of this injection molding machine; 2. The material setting of the push plate 3 has a higher hardness, making the deformation of the fixed template 1 more accurate during testing; 3. The push plate 3 is installed between the plate frame 6 and the moving template 2, and the detection ends of the middle displacement sensor 4 and the end displacement sensor 5 abut against the moving template 2, enabling the detection of the deformation of the moving template 2; 4. The present utility model has universality. By matching push plates 3 of different sizes, template tests for different mold clamping models can be achieved, which can improve efficiency and reduce costs.

[0030] Inspired by the above ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
