Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a testing device, an injection mold for testing, and an inclined slide plate. Background Art

[0002] The opening and closing action of the slide of the existing preform injection mold (injection mold) is generally achieved by the cooperation of the slide plate and the roller (such as Figure 1 As shown). Reference may be made to the Chinese utility model patent application number CN202320677969.7 previously filed by the present applicant, which discloses a slide opening and closing control device and an injection mold. The device includes a slide assembly, a tie bar assembly, and a chute assembly. The slide assembly is connected to the tie bar assembly. Both ends of the tie bar assembly are connected to the chute assembly. The chute assembly is provided with a curved track 34 that extends from bottom to top toward the outside of the mold. The tie bar assembly cooperates with the curved track 34 on the chute assembly via a roller 23. The slide assembly moves along the curved track 34 via the roller 23 to achieve opening and closing.

[0003] Generally speaking, the curved track on the chute assembly, that is, the inclined chute track, is fixed. During the testing process of the injection mold, some preforms will be difficult to demold or cannot be demolded. It is necessary to redesign and process the inclined chute track on the inclined chute plate before testing. In order to ensure the guiding effect of the inclined chute track, a new inclined chute plate must be used each time the inclined chute track is processed. It may be necessary to repeat the above steps for trial and error many times before the inclined chute track is finally determined. This process of obtaining the optimal inclined chute track through multiple trials and errors will undoubtedly increase a lot of production costs and time costs. Utility Model Content

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. The present utility model is not limited to the following embodiments.

[0026] It should be noted that if there are directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0027] In addition, if the description of "first" or "second" etc. is involved in the embodiments of the present utility model, the description of "first" or "second" etc. is only for descriptive purposes and cannot be construed as indicating or implying its relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0028] As Figures 2 to 5 shown, this embodiment discloses a testing device, including a driving mechanism 1, a chute plate 2 and a connecting block 3. The chute plate 2 is installed on the driving mechanism 1. A chute 21 is provided on the chute plate 2. Preferably, the chute extends obliquely along a direction at an angle of 45° with the first direction. One end of the connecting block 3 is connected with a sliding member 4 that cooperates with the chute 21. The sliding member is a sliding part or a rolling part, preferably a bearing. When the driving mechanism 1 drives the chute plate 2 to move along the first direction, based on the cooperation between the chute 21 and the sliding member 4, the connecting block 3 is driven to move along the second direction through the sliding member 4.

[0029] Furthermore, the driving mechanism 1 is driven by a linear motor mechanism. The driving mechanism 1 includes a guide rail 12 and a linear motor 13. The guide rail 12 is arranged along the first direction. The linear motor 13 is slidably fitted on the guide rail 12. The chute plate 2 is installed on the linear motor 13. The driving mechanism 1 drives the chute plate 2 to move along the direction of the guide rail 12 through the linear motor 13. By installing this testing device on an injection molding die, it can drive the slide plate assembly 8 to simulate the mold opening and closing actions. After repeatedly opening and closing multiple times, the optimal mold opening and closing line of the slide plate assembly 8 can be selected. After fitting the mold opening and closing line, the most suitable inclined chute track 51 can be obtained, thereby machining the most suitable inclined chute plate, avoiding the waste of resources caused by repeatedly designing the inclined chute plate multiple times, reducing the production cost, and improving the production efficiency.

[0030] The selection of the optimal mold opening and closing scheme is mainly determined based on factors such as the quality and molding cycle of the products injection molded by the injection molding die. Those of ordinary skill in the art can determine the optimal injection molding scheme based on these factors, and then obtain the corresponding mold opening and closing scheme for this injection molding scheme.

[0031] In this embodiment, the driving mechanism 1 can also be driven by a servo motor mechanism. The driving mechanism 1 includes a servo motor and a screw slider module. The screw slider module is arranged along the first direction and is connected to the rotary driving end of the servo motor. The chute plate 2 is arranged on the slider of the screw slider module.

[0032] Not limited to the above embodiments, the driving mechanism 1 is driven by a servo motor mechanism. The driving mechanism 1 includes a servo motor and a gear-rack module. The rack of the gear-rack group is arranged in the first direction. The gear of the gear-rack group cooperates with the rack of the gear-rack group and is connected to the rotary driving end of the servo motor. The chute plate 2 is arranged on the rack of the gear-rack module.

[0033] It should be noted that if the driving mechanism 1 is a servo motor mechanism, since the screw-slider module and the gear-rack module are variable-speed and variable-direction mechanisms, and the servo motor controls the rotational speed, the moving value of the chute plate 2 needs to be obtained through calculation and conversion, which is not as intuitive and convenient as the linear motor mechanism.

[0034] In this embodiment, the testing device further includes a mounting base 11, and the driving mechanism is arranged on the mounting base 11. At the same time, the number of the testing devices can be reasonably set according to the size of the injection-blow mold, and the number and size of the components in the testing device can also be customized to adapt to different sizes of molds and meet the requirements of different opening and closing forces.

[0035] Furthermore, for the linear motor mechanism, multiple guide rails 12 can be spliced in sequence to meet different length requirements. Multiple linear motors 13 can be installed on one guide rail 12, and multiple chute plates 2, connecting blocks 3 and sliding parts 4 are provided to meet the requirements of different opening and closing forces.

[0036] Based on a testing device disclosed in the above embodiments, this embodiment further provides an injection-blow mold, which includes a top plate assembly 7. The top plate assembly 7 includes a top plate. Multiple groups of slide plate groups 8 are arranged on the top plate along the front and back in the second direction. The slide plate group 8 includes a first slide plate 81 and a second slide plate 82 both extending in the first direction. Among the multiple groups of slide plate groups 8, multiple first slide plates 81 are linked together, and multiple second slide plates � are linked together.

[0037] The testing devices as described above are respectively installed on the front and back sides along the second direction of the top plate in a mirror image manner. The connecting block 3 of the testing device on the front side of the top plate is connected to the first slide plate 81 of the foremost slide plate group 8, and the connecting block of the testing device on the back side of the top plate is connected to the second slide plate 82 of the rearmost slide plate group 8.

[0038] Furthermore, the injection-blow mold further includes a limit trigger 6. The first contacts of the limit trigger 6 are respectively installed on the front and back sides along the second direction of the top plate, and the second contacts of the limit trigger 6 are respectively installed on the chute plates 2 of the testing device.

[0039] In the embodiments of the present utility model, the first direction and the second direction are preferably perpendicular to each other. After the testing device is combined with the injection-blow molding die, the extending direction of the slide plate is the first direction, and the arranging direction of the slide plate group on the top plate is the second direction. In other embodiments, the first direction and the second direction may have an angle other than 90°. The arranging direction of the slide plate group on the top plate is the second direction, and the extending direction of the slide plate is perpendicular to the second direction. The moving direction of the top plate is perpendicular to the plane where the slide plate group is arranged on the top plate, that is, perpendicular to both the first direction and the second direction.

[0040] An inclined chute plate comprises an inclined chute plate body 5 and an inclined chute 51 arranged on the inclined chute plate body 5, and the track of the inclined chute 51 is obtained through simulation testing of the above-mentioned injection-blow molding die.
