With the above structure, this utility model eliminates the ejector plate and ejector pin, and places the inclined ejector seat externally, which not only simplifies the structure of the slider but also significantly reduces the volume of the slider.

Description

Technical Field

[0001] This utility model relates to an injection mold, and more particularly to a slider with an inclined ejector structure. Background Technology

[0002] In injection molded products, snap-hole structures are often encountered. Therefore, after injection molding, the snap-hole is usually removed first, and then the mold is demolded.

[0003] The old tripping structure (such as) Figure 1 As shown, a pin plate 73 and a control mechanism for moving the pin plate 73 are designed within the slider 3. The pin plate 73, in conjunction with the pin 74, prevents the product from sticking to the slider 3 when it moves. A slanted ejector seat is mounted on the pin plate 73 and fixed thereto. A slanted ejector rod is located within the slider 3, which has a slanted hole. The slanted ejector rod is connected to the slanted ejector seat via a guide structure and slides within the slanted hole. One end of the slanted ejector rod has a forming block located outside the slider 3 to participate in the forming of the buckle hole. This structure enables the pin plate 73 to remain stationary under the control mechanism during the initial retraction phase of the slider 3, thus preventing the slanted ejector seat and slanted ejector rod from retracting. This allows the slanted ejector rod to move downwards and disengage. After the slider retracts a certain distance, the pin plate 73, the slanted ejector, and the slider retract synchronously to their limit positions under the control mechanism.

[0004] Traditional solutions require a large amount of internal space for the slider, which not only increases the ejector plate 73, but also makes the slider structure more complex. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a slider with an inclined top structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A slider with an inclined top structure includes a rear template and a slider disposed in the rear template. The structure further includes an inclined top rod and an inclined top seat that can slide on the rear template. The slider has an inclined hole, and the inclined top rod slides into the inclined hole. One end of the inclined top rod has a forming block, and the other end of the inclined top rod slides into the inclined top seat via a guide structure. A control structure is provided between the rear template and the slider to control the movement of the inclined top seat. When the slider moves, the inclined top rod is pressed by the inclined hole, causing the forming block to disengage from the snap-hole of the product. The control structure restricts the movement of the inclined top seat before the forming block disengages from the snap-hole, and releases the restriction on the inclined top seat after the forming block disengages from the snap-hole, allowing the inclined top seat to move with the slider.

[0008] The guiding structure includes a guide block and a seat groove disposed on the inclined top seat. The guide block and the seat groove are slidably engaged, and the other end of the inclined top rod is fixed to the guide block.

[0009] The control structure includes a release groove on the slider, a slot on the rear template, a hole on the slanted ejector, and a movable block in the hole. When the mold is closed, one end of the movable block can be locked in the slot, thereby fixing the slanted ejector to the rear template. After the slider moves a certain distance, the movable block can disengage from the slot and engage in the release groove, thereby allowing the slanted ejector to move together with the slider.

[0010] Both ends of the movable card block are V-shaped, and the card slot is a corresponding V-shaped slot.

[0011] The bottom surface of the slider is provided with a wear-resistant block one, the release groove is provided on the wear-resistant block one, the rear template is provided with a wear-resistant block two, and the slot is provided on the wear-resistant block two.

[0012] The inclined top seat includes a sliding plate and a guide seat with the sliding plate vertically mounted, and the seat groove is vertically mounted inside the guide seat.

[0013] The rear template is equipped with a cylinder mounting plate, and the hydraulic cylinder is fixed on the cylinder mounting plate.

[0014] The beneficial effects of this utility model are as follows: This utility model includes a rear template, a rear inner mold disposed in the rear template, and a slider. The rear template is provided with a hydraulic cylinder connected to the slider. It also includes an inclined ejector rod and an inclined ejector seat that can slide on the rear template. The slider is provided with an inclined hole. The inclined ejector rod slides in conjunction with the inclined hole. One end of the inclined ejector rod is provided with a forming block. The other end of the inclined ejector rod slides in conjunction with the inclined ejector seat through a guide structure. A control structure that can control the movement of the inclined ejector seat is provided between the rear template and the slider.

[0015] With the above structure, this utility model eliminates the ejector plate and ejector pin, and places the inclined ejector seat externally, which not only simplifies the structure of the slider, but also greatly reduces the volume of the slider. Attached Figure Description

[0027] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0028] Reference Figures 2 to 4This utility model discloses a slider inclined top structure, including a rear template 1, a rear inner mold 2 disposed in the rear template 1, and a slider 3. The rear template 1 is provided with a hydraulic cylinder 4 connected to the slider 3. The slider 3 moves along the rear template 1 by being driven by the hydraulic cylinder 4. Of course, for ease of manufacturing, the rear template 1 is provided with a hydraulic cylinder hanging plate 5, and the hydraulic cylinder 4 is fixed on the hydraulic cylinder hanging plate 5.

[0029] It also includes a slanted ejector rod 6 and a slanted ejector seat 7 that can slide on the rear mold plate 1. The slider 3 is provided with a slanted hole 8, and the slanted ejector rod 6 slides in conjunction with the slanted hole 8. One end of the slanted ejector rod 6 is provided with a forming block 9, and the surface of the forming block 9 forms part of the forming cavity wall. Of course, the forming cavity wall also includes the corresponding surfaces of the slider 3 and the rear inner mold 2. The forming block 9 is used to form a snap-fit ​​hole, which is a vertical hole. Therefore, the forming block 9 needs to move downward when it is released. The downward direction in this application is opposite to the moving direction of the front mold plate when the mold is opened. The slanted hole 8 forms an acute angle with the moving direction of the front mold plate. Therefore, when the slider 3 moves, the slanted hole 8 will squeeze the slanted ejector rod 6 to move. The moving direction of the slanted ejector rod 6 can be decomposed into a downward direction and a horizontal direction.

[0030] The other end of the inclined top rod 6 is slidably engaged with the inclined top seat 7 through a guide structure, and a control structure capable of controlling the movement of the inclined top seat 7 is provided between the rear template 1 and the slider 3.

[0031] The principle of this structure is as follows: When the mold opens, the front template (not shown in the figure) moves first. After it moves to completely separate from the rear template 1, the hydraulic cylinder 4 is activated, driving the slider 3 to move within the rear template 1. When the slider 3 moves, it can squeeze the inclined ejector rod 6 through the inclined hole 8, thereby causing the molding block 9 to disengage from the product's snap hole. The control structure can restrict the movement of the inclined ejector seat 7 before the molding block 9 disengages from the product's snap hole. Because the inclined ejector seat 7 is fixed due to the restriction of the control structure, the horizontal movement of the inclined ejector rod 6 is restricted by the inclined ejector seat 7. Therefore, the inclined ejector rod 6 can only move downwards. Of course, the other end of the inclined ejector rod 6 is also guided downwards by the guide structure, thereby causing the molding block 9 to disengage. After disengagement, in order to avoid hindering the product from being ejected, the control structure releases the restriction on the inclined ejector seat 7, and the slider 3 continues to move. Due to the stroke limitation of the guide structure, the inclined ejector rod 6 will not move downwards at this time, but can only move horizontally, thereby causing the inclined ejector seat 7 to move horizontally together until the end of the horizontal stroke. Only then can the product be ejected from the mold.

[0032] This structure eliminates the ejector plate and ejector pins, redesigns the control structure, and places the angled ejector seat 7 externally. This not only simplifies the structure of the slider 3 but also significantly reduces its volume. Since the material of the injection-molded product is not prone to sticking to the slider 3, eliminating the ejector plate and ejector pins does not affect product demolding.

[0033] As shown in the figure, the guiding structure includes a guide block 10 and a seat slide groove 11 disposed on the inclined top seat 7. The guide block 10 and the seat slide groove 11 are slidably engaged. The other end of the inclined top rod 6 is fixed to the guide block 10. The seat slide groove 11 is preferably a T-shaped groove.

[0034] As shown in the figure, the control structure includes a release groove 12 on the slider 3, a slot 13 on the rear template 1, a slot 14 on the inclined ejector 7, and a movable block 15 located in the slot 14. When the mold is closed, one end of the movable block 15 can be locked in the slot 13, thereby fixing the inclined ejector 7 to the rear template 1. After the slider 3 moves a certain distance, the release groove 12 above the movable block 15 provides space for the movable block 15 to rise. Therefore, the inclined ejector 7 squeezes the movable block 15. Both ends of the movable block 15 are V-shaped ends, and the slot 13 is a corresponding V-shaped groove. Therefore, the movable block 15 can rise along the V-shaped groove and its end is inserted into the release groove 12 until it is disengaged from the slot 13, so that the inclined ejector 7 can move together with the slider 3 until it moves to the predetermined position. Of course, as a preferred structure, the rear template 1 has positioning glass beads 16, and the inclined ejector seat 7 has two positioning grooves. When the mold is closed, the positioning glass beads 16 can be inserted into one positioning groove, thereby realizing the positioning of the inclined ejector seat 7 when the mold is closed. When the inclined ejector seat 7 moves to the predetermined position, the positioning glass beads 16 can be inserted into the other positioning groove. The positioning glass beads 16 are external components, so their specific structure will not be described in detail.

[0035] To extend the service life, the bottom surface of the slider 3 is provided with a wear-resistant block 17, the release groove 12 is provided on the wear-resistant block 17, the rear template 1 is provided with a wear-resistant block 18, and the slot 13 is provided on the wear-resistant block 18.

[0036] As shown in the figure, the inclined top seat 7 includes a sliding plate 71 and a guide seat 72 with the vertical sliding plate 71. The seat groove 11 is vertically arranged in the guide seat 72. The rear template 1 has a rear mold groove 19, which is a T-shaped groove. The sliding plate 71 slides with the T-shaped groove to realize the movement of the inclined top seat 7.

[0037] The above provides a detailed description of a slider inclined top structure provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
