Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and more specifically, to an inclined guide column slider structure and an injection mold. Background Art

[0002] Injection molding is a common way to manufacture workpieces. The injection molding material is melted and injected into the injection mold to form. The injection mold includes a lower mold body, an upper mold body and an injection slider. The upper mold body is moved downward and buckled on the lower mold body to complete the mold closing. The injection molding material is melted and injected between the lower mold body and the upper mold body. After the injection molding material solidifies, the upper mold body is moved upward and away from the lower mold body to complete the mold opening. The injection slider is an important part in the mold. Its function is to realize the parts that need to move or the sliding closing function during the forming process by sliding close to and away from the lower mold body. Such as driving the lateral core pulling movement, etc.

[0003] The commonly used driving method for the slider is the inclined guide column slider structure, such as Figure 6 As shown, the inclined guide pin 1 is fixedly connected to the upper mold body, and the inclined guide pin 1 is slidably inserted into the inclined guide hole set on the slider 2. When the mold is closed, the inclined guide pin 1 moves downward with the upper mold body, and the inclined guide pin 1 slides along the inclined guide hole to drive the slider 2 to slide inward. When the mold is opened, the inclined guide pin 1 moves upward with the upper mold body, and the inclined guide pin 1 slides along the inclined guide hole to drive the slider 2 to slide outward. However, this method can only be applied when the sliders slide synchronously during mold opening and mold closing.

[0004] Sometimes it is necessary to slide the slider inwards before closing the mold to press against the internal insert to ensure the stability of the insert. In this case, the slider must be slid inwards before closing the mold and the slider slides outwards synchronously when opening the mold. For this situation, the existing inclined guide column slider structure is not applicable. Utility Model Content

[0005] In order to overcome the problems existing in the related art to a certain extent, the purpose of the present application is to provide an inclined guide post slider structure and an injection mold, which can solve the problem that the existing inclined guide post slider structure cannot be applied to the situation where the slider needs to be slid inward before mold closing and the slider simultaneously slides outward when the mold is opened. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided in the present application are described in detail below.

[0006] The present application provides an inclined guide column slider structure, comprising:

[0007] An inclined guide column, wherein a first end of the inclined guide column is connected to the upper mold body, and a second end of the inclined guide column is inclined downward away from the upper mold body;

[0008] A slider is slidably arranged on the base, the slider can slide close to or away from the lower mold body, a through slot is formed through the slider, and the inclined guide column can extend into the through slot;

[0014] Optionally, a mounting groove is provided on the outer wall of the sliding block, and the baffle is installed in the mounting groove.

[0015] Optionally, the elastic member is a spring, a first mounting hole is provided on the baffle, and the first end of the elastic member is inserted into the first mounting hole.

[0016] Optionally, a second mounting hole is provided on the inner end surface of the telescopic column, and the second end of the elastic member is inserted into the second mounting hole.

[0017] The present application also provides an injection mold, comprising any of the inclined guide column slider structures described above.

[0018] The technical solution provided by this application may have the following beneficial effects:

[0019] The present application provides a structure of an inclined guide column slider, wherein the first end of the inclined guide column is connected to the upper mold body, and the second end of the inclined guide column is away from the upper mold body and tilted downward. The slider can slide close to and away from the lower mold body. A through groove is provided on the slider, and a sliding hole is provided on the side wall of the through groove. The telescopic column is slidably inserted into the sliding hole, and the inner end of the telescopic column is connected to the bottom of the sliding hole through an elastic member. An inclined surface is provided on the side of the outer end of the telescopic column away from the lower mold body. During the mold closing process, the upper mold body descends and drives the inclined guide column to descend together and enter the through groove. At this time, the side of the inclined guide column close to the lower mold body is against the inclined surface of the outer end of the telescopic column. As the upper mold body continues to descend, the side of the inclined guide column close to the lower mold body slides along the inclined surface, thereby squeezing the telescopic column to slide toward the bottom of the sliding hole. After the inclined guide column leaves the inclined surface, it continues to descend to complete the mold closing. At this time, the inclined guide column completely leaves the outer end of the telescopic column. Under the rebound effect of the elastic member, the inclined guide column is pushed back to its original position. After the injection molding is completed, the mold is opened. During the mold opening process, the upper mold body rises and drives the inclined guide pillar to rise together. The inclined guide pillar abuts against the side of the telescopic column side wall close to the lower mold body. As the upper mold body continues to rise, the side of the telescopic column side wall close to the lower mold body slides along the side wall of the inclined guide pillar, thereby driving the slider to slide away from the lower mold body. In this way, the slider slides inward before the mold is closed, and the slider slides outward synchronously when the mold is opened.

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0032] refer to Figure 1-5 The present embodiment provides an inclined guide column and slider structure, including an inclined guide column 1, a slider 2, and a telescopic column 3. The first end of the inclined guide column 1 is connected to the upper mold body, and the second end of the inclined guide column 1 is away from the upper mold body and tilted downward. When the mold is opened, the upper mold body rises and drives the inclined guide column 1 to rise together. When the mold is closed, the upper mold body descends and drives the inclined guide column 1 to descend together.

[0033] A slide rail is provided on the slider 2, and a slide groove is provided on the base outside the lower mold body. The slider 2 is slidably provided on the base outside the lower mold body, so that the slider 2 can slide close to and away from the lower mold body. An insert can be provided on the slider 2 to be inserted into the lower mold body. When the slider 2 slides close to the lower mold body, the insert presses against the insert to stabilize the insert, and when the slider 2 slides away from the lower mold body, the insert leaves the insert, and the insert can be taken out.

[0034] A through slot 5 is provided on the slider 2, and the through slot 5 passes through the top and bottom surfaces of the slider 2 respectively. When the upper mold body is closed, the upper mold body descends and drives the inclined guide column 1 to descend together and enter the through slot 5. A sliding hole 4 is provided on the side wall of the through slot 5, and the telescopic column 3 is slidably inserted into the sliding hole 4. The inner end of the telescopic column 3 is connected to the bottom of the sliding hole 4 through an elastic member 9. When the telescopic column 3 slides toward the bottom of the sliding hole 4, the elastic member 9 is compressed, and the elastic member 9 rebounds to push the telescopic column 3 to slide away from the bottom of the sliding hole 4. A slope 8 is provided on the side of the outer end of the telescopic column 3 away from the lower mold body.

[0035] After the insert is placed in the lower mold body, slide the slider 2 close to the lower mold body, and the plug on the slider 2 is inserted into the lower mold body and pressed against the insert to stabilize the insert. At this time, the mold is closed. During the mold closing process, the upper mold body descends and drives the inclined guide pillar 1 to descend together and enter the through groove 5. At this time, the side of the inclined guide pillar 1 close to the lower mold body is against the inclined surface 8 at the outer end of the telescopic column 3. As the upper mold body continues to descend, the side of the inclined guide pillar 1 close to the lower mold body slides along the inclined surface 8, thereby squeezing the telescopic column 3 and making it slide to the bottom of the sliding hole 4. After the inclined guide pillar 1 leaves the inclined surface 8, it continues to descend to complete the mold closing. At this time, the inclined guide pillar 1 completely leaves the outer end of the telescopic column 3. Under the rebound effect of the elastic member 9, the telescopic column 3 is pushed back to its original position.

[0036] After the injection molding is completed, the mold is opened. During the mold opening process, the upper mold body rises and drives the inclined guide column 1 to rise together. The inclined guide column 1 rests on the side wall of the telescopic column 3 close to the lower mold body. As the upper mold body continues to rise, the side wall of the telescopic column 3 close to the lower mold body slides along the side wall of the inclined guide column 1, thereby driving the slider 2 to slide away from the lower mold body.

[0037] With this arrangement, the slider is slid inwards before the mold is closed, and the slider is slid outwards synchronously when the mold is opened.

[0038] As an optional embodiment, a sliding hole 4 is provided on the side walls on both sides of the through slot 5, and a telescopic column 3 is slidably arranged in each sliding hole 4. The two telescopic columns 3 are coaxially arranged. During the mold closing process, the upper mold body descends and drives the inclined guide column 1 to descend together and enter the through slot 5. At this time, the side of the inclined guide column 1 close to the lower mold body respectively abuts against the inclined surface 8 at the outer ends of the two telescopic columns 3. As the upper mold body continues to descend, the side of the inclined guide column 1 close to the lower mold body slides along the inclined surface 8 at the outer ends of the two telescopic columns 3, thereby squeezing the telescopic columns 3 respectively. The two telescopic columns 3 are caused to move away from each other and slide toward the bottom of the sliding hole 4. After the inclined guide column 1 leaves the inclined surface 8, it continues to descend to complete the mold closing. At this time, the inclined guide column 1 completely leaves the outer ends of the two telescopic columns 3. Under the rebound action of the elastic member 9, the two telescopic columns 3 are pushed back to their original positions respectively.

[0039] During the mold opening process, the upper mold body rises and drives the inclined guide column 1 to rise together. The inclined guide column 1 rests on the side wall of the two telescopic columns 3 close to the lower mold body. As the upper mold body continues to rise, the side wall of the two telescopic columns 3 close to the lower mold body slides along the side wall of the inclined guide column 1, thereby driving the slider 2 to slide away from the lower mold body.

[0040] In some embodiments, a slot 6 is provided on the side of the inclined guide pillar 1 away from the lower mold body. During the mold opening process, the upper mold body rises and drives the inclined guide pillar 1 to rise together, until the side of the outer end of the telescopic column 3 close to the lower mold body is stuck in the slot 6. As the upper mold body continues to rise, the side of the outer end of the telescopic column 3 close to the lower mold body slides along the slot 6, thereby driving the slider 2 to slide away from the lower mold body.

[0041] As an optional embodiment, it further includes: a baffle 7. The sliding hole 4 penetrates the outer wall of the slider 2. The baffle 7 is fixedly connected to the outer wall of the slider 2, so that the baffle 7 closes the sliding hole 4 to form the bottom of the sliding hole 4. The first end of the elastic member 9 is connected to the baffle 7, and the second end of the elastic member 9 is connected to the inner end of the telescopic column 3. The installation is more convenient.

[0042] Furthermore, a mounting groove is provided on the outer wall of the sliding block 2. After the baffle plate 7 is installed in the mounting groove, the baffle plate 7 is located in the mounting groove to reduce interference.

[0043] The elastic member 9 is a spring, a first mounting hole is provided on the baffle 7, and the first end of the elastic member 9 is fixedly inserted in the first mounting hole to complete the connection. A second mounting hole is provided on the inner end surface of the telescopic column 3, and the second end of the elastic member 9 is fixedly inserted in the second mounting hole to complete the connection.

[0044] The present application also provides an injection mold, including the inclined guide column slider structure in the above embodiment.
