Sliding block and core-pulling optimization structure

Abstract

The utility model relates to a sliding block and a core-pulling optimization structure. If an oil cylinder of an existing mold core-pulling structure loses efficacy or deviates, the risk of mold collision exists during mold opening. The rear mold structure comprises a plate A, a plate B and a rear mold core, and is characterized in that a product to be machined is arranged on the rear mold core, a rear mold elastic plate is arranged below the plate B, an inner drawer guide block is arranged in the center of the rear mold elastic plate, and a rear mold inner drawer and a sliding block are arranged on the two sides of the product; and when the rear mold elastic plate is bounced off, the rear mold inner drawer and the inner drawer guide block are driven to move synchronously. The die collision risk is avoided, the occupied space of the die is reduced, and the cost is saved.

Description

Technical Field

[0001] This utility model relates to the improvement of core-pulling mold structure, and particularly to a slider and optimized core-pulling structure. Background Technology

[0002] like Figure 1 and Figure 2 As shown, there is a type of product that requires core pulling in the mold at the center and both sides. An inclined ejector structure is set at the center of the product, and hydraulic cylinders are set on both sides of the product. The hydraulic cylinders drive the sliders to complete the core pulling. Since the internal core pulling space of the existing product is sufficient, this inclined ejector structure can achieve demolding.

[0003] The working process is as follows: before the mold opens, the hydraulic cylinder drives the slider to disengage, the angled ejector pushes out, the rear mold buckles to disengage, and the product is smoothly ejected from the mold. Because the ejector stroke is relatively long, the ejection is also longer. The mold is relatively large. When the mold opens and closes, the slider and angled ejector return to their original positions in a specific order. If the hydraulic cylinder fails or deviates, the risk of mold collision is high.

[0004] Therefore, the above-mentioned angled core-pulling structure has the following defects:

[0005] 1. High risk of mold collision (if the hydraulic cylinder fails or deviates, there is a risk of mold collision when opening the mold).

[0006] 2. Because the ejection distance of the inclined ejector is relatively long (the core pulling distance is relatively long), it will occupy more mold space, resulting in a waste of machine space. Summary of the Invention

[0007] To address the problems existing in the prior art, this utility model proposes an optimized slider and core-pulling structure to solve the risk of mold collision, reduce the space occupied by the mold, and save costs.

[0008] Therefore, the technical solution adopted by this utility model is: an optimized slider and core-pulling structure, including an A plate, a B plate and a rear mold core, characterized in that the product to be processed is set on the rear mold core, a rear mold spring plate is set below the B plate, an inner pull guide block is set at the center of the rear mold spring plate, and rear mold inner pulls and sliders are set on both sides of the product. When the rear mold spring plate opens, it drives the rear mold inner pulls and inner pull guide blocks to move synchronously.

[0009] Preferably, the device also includes a fastening assembly disposed on the sides of plates A and B, wherein the fastening assembly holds plates A and B in place before the rear mold spring plate fully pops open.

[0010] Preferably, the rear mold spring plate is connected to the slider with a bent pin, the slider with the bent pin is connected to the slider, and the inner side of the slider is connected to the rear mold inner drawer.

[0011] Preferably, the rear mold spring plate is connected to the inner guide block by screws, and the rear mold spring plate is connected to the slider bending pin by screws.

[0012] Preferably, the fastening assembly includes an A-plate fastening mechanism and a spring plate fastening mechanism.

[0013] This invention, without changing the spatial position of the existing mold product, changes the rear mold inclined top structure to an internal pulling structure, adds a spring plate to the rear mold, and uses the spring plate to disengage the slider, eliminating the hydraulic cylinder structure. This ensures that the rear mold internal pulling and the slider move synchronously while achieving demolding, avoiding the risk of mold collision. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 3-6 The slide block and core-pulling optimization structure shown includes an A plate, a B plate 2, and a rear mold core 1. The product to be processed 5 is set on the rear mold core 1. A rear mold spring plate 12 is set below the B plate. An inner pull guide block 4 is set at the center of the rear mold spring plate 12. The rear mold inner pull 3 and the slide block 7 are set on both sides of the product. When the rear mold spring plate 12 springs open, it drives the rear mold inner pull 3 and the inner pull guide block 4 to move synchronously.

[0023] Specifically, it also includes a fastening assembly located on the sides of plates A and B. Before the rear mold spring plate fully pops open, the fastening assembly holds plates A and B still.

[0024] Specifically, the rear mold spring plate 12 is connected to the slider bend pin 6, which is connected to the slider 7. The inner side of the slider 7 is connected to the rear mold inner drawer 3. When the rear mold spring plate 12 springs open, it drives the slider bend pin, which in turn drives the slider and the rear mold inner drawer to move outward.

[0025] Specifically, the rear mold spring plate 12 is connected to the inner guide block 4 by screws, and the rear mold spring plate 12 is connected to the slider bending pin 6 by screws.

[0026] Specifically, the fastening assembly includes A-plate fastening mechanism 8 and spring-loaded fastening mechanism 11. The two fastening mechanisms respectively hold A-plate and B-plate.

[0027] The working state of this utility model is as follows:

[0028] Figure 4 In the mold opening state: At this time, the A plate clamping machine 8 and the spring plate clamping machine 11 hold the A / B plates in place. The rear mold spring plate 12 pulls open first, driving the slider 7 and the inner guide block 4 to move simultaneously. The slider 7 and the rear mold inner guide block 3 open at the same time, and the mold is demolded by inverted clamping. Then the A / B plates are pulled open again, and the product is ejected normally, completing the injection molding.

[0029] Figure 5 In the mold closing state: the sequence of motion in this state is as follows: the rear mold spring plate does not move first (the second latch tongue 10 blocks the spring plate latch 11), the A / B plates close the mold first, after the A plate latch 8 pops open the first tongue 9, the spring plate then drives the slider and the inner pull to move simultaneously to complete the mold closing.

[0030] This invention, without changing the spatial position of the existing mold product, changes the rear mold inclined top structure to an internal pulling structure, adds a spring plate to the rear mold, and uses the spring plate to disengage the slider, eliminating the hydraulic cylinder structure. This ensures that the rear mold internal pulling and the slider move synchronously while achieving demolding, avoiding the risk of mold collision.

[0031] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
