[0002] In the prior art, many injection molded workpieces are installed using snap-on mounting methods, such as Figure 1 As shown, the workpiece 100 has two relatively arranged buckles 101. During the injection molding process, each buckle 101 needs to be injection molded separately, which requires the linkage of multiple mold cores. The overall structure of the mold is more complicated, which is not only difficult to achieve linkage in a small space, but also has a high application cost. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a part clip inclined ejection slider mechanism which can realize synchronous demoulding and core pulling of two mold cores, has a simple and reliable linkage relationship, and has low mold cost, in view of the shortcomings of the existing technology.
[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions.
[0005] A part snap-on inclined ejection slider mechanism comprises a support, a slider and two mold cores, the support is provided with a slide, the slider is arranged in the slide and the two slide together, a trapezoidal guide head is formed at the front end of the slider, the width of the trapezoidal guide head gradually increases from front to back, the front end of the slider is provided with two slide grooves distributed in an "eight" shape, the two slide grooves are symmetrically arranged on the left and right sides of the trapezoidal guide head, two mold cores are respectively arranged in the two slide grooves, and the mold cores slide together with the slide grooves, a forming end is formed on the outer side of the front end of the mold core, the rear end of the mold core abuts and cooperates with the support, and the mold core can slide left and right relative to the support.
[0006] Preferably, a push block protruding outward is formed at the rear end of the mold core, and two stop blocks are fixed to the top of the support, with the rear end of the push block abutting and fitting with the front end of the stop block.
[0007] Preferably, a limiting notch of a preset length is provided on the outer side of the mold core, and a limiting block is formed on the outer edge of the slide groove. The limiting block is clamped in the limiting notch and the two are slidably matched.

Then, the mold is closed and injection is performed. After the workpiece is injection molded, the preset driving mechanism drives the slider to slide backward. Based on the abutment and matching relationship between the rear end of the mold core and the support, the trapezoidal guide head retreats relative to the two mold cores.

Compared with the existing technology, the utility model can not only realize the synchronous demoulding and core pulling of the two mold cores, but also has a simple and reliable linkage relationship. There is no need to set a separate linkage mechanism for each clip, which can effectively save mold costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0017] The utility model discloses a parts buckle inclined ejection slider mechanism, combined with Figures 1 to 4As shown, it includes a support 1, a slider 2 and two core molds 3. The support 1 is provided with a slide 10, the slider 2 is arranged in the slide 10 and the two are slidably matched. A trapezoidal guide head 20 is formed at the front end of the slider 2, and the width of the trapezoidal guide head 20 gradually increases from front to back. The front end of the slider 2 is provided with two slide grooves 21 distributed in an "eight" shape, and the two slide grooves 21 are symmetrically arranged on the left and right sides of the trapezoidal guide head 20. Two core molds 3 are respectively arranged in the two slide grooves 21, and the core mold 3 is slidably matched with the slide grooves 21. A forming end head 30 is formed on the outer side of the front end of the core mold 3, and the rear end of the core mold 3 is in abutment with the support 1, and the core mold 3 can slide left and right relative to the support 1.
[0018] When the slider 2 is pushed forward, the two mold cores 3 are moved to the left and right sides, and the molding end 30 is slidably matched with the two mold cores 3 and driven to slide to the left and right sides, until the molding end 30 outside the front end of the mold core 3 enters the specified position in the mold cavity, and then the mold is closed and injection molding is performed. After the workpiece 100 is injection molded, the slider 2 is driven by the preset driving mechanism to slide backward. Based on the abutting and matching relationship between the rear end of the mold core 3 and the support 1, the trapezoidal guide head 20 retreats relative to the two mold cores 3. Under the action of external force or the matching relationship between the two mold cores 3 and the slider 2, the two mold cores 3 can be relatively close to each other, thereby separating the molding end 30 from the buckle 101 on the workpiece 100, completing the inclined top demolding function. Compared with the existing technology, the utility model can realize the synchronous demoulding and core pulling of two mold cores, and the linkage relationship is simple and reliable. There is no need to set up a separate linkage mechanism for each buckle, which can effectively save mold costs.
[0019] Regarding the preferred abutment and matching relationship between the mold core 3 and the support 1, Figure 3 and Figure 4 As shown, in this embodiment, the rear end of the mold core 3 is formed with an outwardly protruding push block 31, and two stop blocks 11 are fixed to the top of the support 1. The rear ends of the push blocks 31 abut against the front ends of the stop blocks 11. The stop blocks 11 and the support 1 are detachable and easy to assemble. In actual applications, the stop blocks 11 can also be integrally formed with the support 1.
[0020] As a preferred method, combining Figure 3 and Figure 4As shown, the outer side of the mold core 3 is provided with a limit slot 32 of a preset length, and the outer edge of the slide groove 21 forms a limit block 22, which is clamped in the limit slot 32 and the two slide together. In the above structure, the limit block 22 is slidably arranged in the limit slot 32. When the slider 2 slides backward and performs the demolding action, the limit block 22 applies a thrust to the inner wall of the limit slot 32, and the two mold cores 3 are driven relatively close by the two limit blocks 22, and the two molding ends 30 are synchronously separated from the two buckles 101 on the workpiece 100. Based on the above structure, this embodiment does not need to set up an additional mechanism to drive the mold core 3 relatively close, so the linkage relationship is more compact and simplified.
[0021] To make the top of the mold flat, in this example, see Figure 2 The top of the limit block 22, the top of the mold core 3 and the top of the trapezoidal guide head 20 are flush with each other.
[0022] In the process of mold closing and demoulding, the slider 2 is driven to slide backward by a preset driving mechanism in this embodiment. The preset driving mechanism may be an inclined rod mechanism, such as Figure 3 and Figure 4 As shown, the driving mechanism in this embodiment includes an oblique driving block 4, and the slider 2 is provided with an oblique sliding groove 23 running through the top and bottom sides. The oblique driving block 4 is arranged above the slider 2, and the oblique driving block 4 can be inserted into the oblique sliding groove 23 and the two are slidably matched.
[0023] In order to respectively confine the two mold cores 3 in the two chute grooves 21 , in this embodiment, a limiting pressure block 5 is fixed on the top of the trapezoidal guide head 20 , and the limiting pressure block 5 covers the top of the chute groove 21 .
[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
