Description

Technical Field

[0001] The utility model relates to the technical field of the prior reset mechanism of large slide blocks of molds, in particular to the prior reset mechanism of four-sided large slide blocks with small sprue gating for the frame of financial equipment. Background Technique

[0002] When the plastic frame of financial equipment is cast and injection molded using a mold, it is often the case that the reset of the slide block on the mold precedes the reset of the ejector pin, resulting in a collision between the slide block and the ejector pin or lifter, causing damage to the mold or product quality problems. Therefore, a multi-sided large slide block prior reset mechanism is generally installed on both sides of the mold. The large slide block prior reset mechanism ensures that when the mold is opened or closed, the large slide block can first return to its initial position, thus avoiding collisions with other components, protecting the structure of the mold. At the same time, the large slide block prior reset mechanism ensures that the product can safely and completely be separated from the mold, ensuring the appearance and dimensional accuracy of the product.

[0003] When using the same mold to cast frames with different shapes or structures, not only the injection mold cavities on the injection plate need to be adjusted, but also the reset moving distance of the large slide block prior reset mechanism needs to be adjusted. Because the shape, structure, and functional requirements of the product determine the number and position of the slide blocks in the mold. In order to meet the specific structure of the product, some slide blocks need to move a longer distance to ensure the complete demolding or molding of the product. However, currently, most reset mechanisms drive the transmission block to rotate by the downward movement of the movable plate, and the rotation of the transmission block makes the fixed block drive the bottom mold panel of the mold to be reset first. This kind of large slide block prior reset mechanism is not easy to adjust the appropriate reset moving distance according to the injection needs of the product, resulting in that one kind of large slide block reset mechanism cannot be applied to the processing of different frames. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a prior reset mechanism of four-sided large slide blocks with small sprue gating for the frame of financial equipment to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] The prior reset mechanism of four-sided large slide blocks with small sprue gating for the frame of financial equipment includes a mold body. The mold body includes a moving mold base. A cavity seat is arranged below the moving mold base. A bottom mold base is arranged at the bottom of the cavity seat. A bottom mold panel is attached to the top surface of the bottom mold base. Positioning blocks are fixedly arranged on both opposite sides at the two ends of the cavity seat. Fixed blocks are fixedly arranged on both opposite sides at the two ends of the bottom mold panel. An activity plate is slidably inserted between adjacent positioning blocks and fixed blocks. The top end of the activity plate is fixedly connected to the moving mold base. A transmission mechanism is arranged between the fixed block and the activity plate. The transmission mechanism includes a connecting shaft fixedly connected to the cavity seat. Transmission block one, transmission block two, transmission block three, and transmission block four are rotatably sleeved on the outer side of the connecting shaft along its length direction.

[0007] Furthermore, a reset spring is fixed between the mold cavity base and the bottom mold panel, and the bottom mold panel is slidably connected to the bottom mold base.

[0008] Furthermore, screw holes are provided at the tops of the positioning block, the fixed block and the movable plate, and the positioning block, the fixed block and the movable plate are detachably and fixedly connected to the mold body by screws.

[0009] Furthermore, the distance between the positioning block and the fixed block is greater than the thickness of the movable plate, and one side of the movable plate is slidably abutted against the positioning block.

[0010] Furthermore, the width of the first transmission block is smaller than the width of the second transmission block, the width of the second transmission block is smaller than the width of the third transmission block, and the width of the third transmission block is smaller than the width of the fourth transmission block.

[0011] Furthermore, one end of the connecting shaft is provided with a thread, and a nut is screwed on the outside of the thread. The bottom ends of the movable plate, the first transmission block, the second transmission block, the third transmission block and the fourth transmission block are all arranged as arc-shaped surfaces.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The movable mold base drives the movable plate to move downward. The bottom end of the movable plate abuts against the first transmission block, and the first transmission block rotates around the connecting shaft towards the fixed block, thereby pushing the fixed block downward by the first transmission block, so that the fixed block drives the bottom mold panel to move downward along the mold cavity base. It realizes that the bottom mold panel can move downward first during the downward movement of the movable mold base for mold closing, avoiding the collision between the mold components on the top of the bottom mold panel and other components, and protecting the structure of the mold.

[0014] 2. By rotatably sleeving a plurality of transmission blocks (including the first transmission block, the second transmission block, the third transmission block and the fourth transmission block) on the connecting shaft, and from the first transmission block to the fourth transmission block, the width of the transmission block gradually increases. According to the distance requirement for the reset downward movement of the fixed block, the transmission blocks at different positions can be rotated above the fixed block, and then the fixed block can drive the bottom mold panel to move downward by different distances under the downward push of the movable plate, realizing the adjustment of the appropriate reset movement distance according to the injection molding needs of the product. A large travel position reset mechanism can be applied to different frame processing. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Example 1, please refer to Figures 1-4 , in the embodiment of the present utility model, a fine gate ingate four-side large slide core pre-ejection mechanism for a financial equipment frame includes a mold body 100. The mold body 100 includes a moving die base 110. A cavity seat 120 is arranged below the moving die base 110. A bottom die base 130 is arranged at the bottom of the cavity seat 120. A bottom die panel 140 is attached to the top surface of the bottom die base 130. Positioning blocks 121 are fixedly arranged on both opposite sides of the cavity seat 120. Fixing blocks 141 are fixedly arranged on both opposite sides of the bottom die panel 140. A movable plate 200 is slidably inserted between adjacent positioning blocks 121 and fixing blocks 141. The top end of the movable plate 200 is fixedly connected to the moving die base 110. A transmission mechanism 300 is arranged between the fixing block 141 and the movable plate 200. The transmission mechanism 300 includes a connecting shaft 310 fixedly connected to the cavity seat 120. A driving block one 320, a driving block two 330, a driving block three 340, and a driving block four 350 are rotatably sleeved on the outer side of the connecting shaft 310 along its length direction.

[0022] Specifically, a first driving block 320, a second driving block 330, a third driving block 340, and a fourth driving block 350 are rotatably sleeved on the connecting shaft 310. From the first driving block 320 to the fourth driving block 350, the width of the driving block gradually increases. By rotating the driving blocks at different positions above the fixed block 141 and then under the downward push of the movable plate 200, the fixed block 141 can drive the bottom die panel 140 to move downward by different distances, achieving the adjustment of the appropriate reset moving distance according to the injection molding requirements of the product. A large die slide reset mechanism can be applied to different frame processing, expanding the application range of the large die slide pre-reset mechanism.

[0023] As Figure 1 shown, in this embodiment, a reset spring 142 is fixed between the cavity base 120 and the bottom die panel 140, and the bottom die panel 140 is slidably connected to the bottom die base 130.

[0024] In this embodiment, in the initial state, the moving die base 110 is located above the cavity base 120, and the bottom die panel 140 is located inside the cavity base 120. At this time, the reset spring 142 is in a natural state. When the movable plate 200 drives the driving block to move downward, the driving block rotates to drive the fixed block 141 and the bottom die panel 140 to move downward. At this time, the reset spring 142 is in a compressed state. The compression elastic force of the reset spring 142 enables the bottom die panel 140 to automatically return to the initial position when the movable plate 200 moves upward later.

[0025] As Figure 2 shown, in this embodiment, screw holes are provided at the tops of the positioning block 121, the fixed block 141, and the movable plate 200. The positioning block 121, the fixed block 141, and the movable plate 200 are detachably and fixedly connected to the mold body 100 by screws. The screw holes facilitate the detachable installation and fixation of the positioning block 121, the fixed block 141, and the movable plate 200 to the mold body 100 using screws.

[0026] As Figure 2 and Figure 4 shown, in this embodiment, the distance between the positioning block 121 and the fixed block 141 is greater than the thickness of the movable plate 200. One side of the movable plate 200 is slidably abutted against the positioning block 121, so that the movable plate 200 can move stably between the positioning block 121 and the fixed block 141.

[0027] As Figure 3 shown, in this embodiment, the width of the first driving block 320 is smaller than the width of the second driving block 330, the width of the second driving block 330 is smaller than the width of the third driving block 340, and the width of the third driving block 340 is smaller than the width of the fourth driving block 350.

[0028] In this embodiment, the transmission blocks of different widths are rotated to the top of the fixed block 141, and then the fixed block 141 and the bottom mold panel 140 are moved down by different distances as the movable plate 200 moves down. Figure 4 The movable plate 200 brings the transmission block three 340 to push the fixed block 141, and the fixed block 141 moves down to the height of position b. The movable plate 200 brings the transmission block one 320 to push the fixed block 141, and the fixed block 141 moves down to the height of position a. The height of position b is lower than the height of position a, so the transmission block with a larger width can cause the reset mechanism in the present application to move downward a greater distance.

[0029] Embodiment 2, based on embodiment 1, is to enable a movable plate 200 to rotate with a plurality of transmission blocks at different positions.

[0030] like Figure 3 As shown, in this embodiment, a thread is provided at one end of the connecting shaft 310, and a nut 311 is screwed into the outer side of the thread, and the bottom ends of the movable plate 200, transmission block 1 320, transmission block 2 330, transmission block 3 340 and transmission block 4 350 are all arranged to be arc-shaped surfaces, and the distance between transmission block 1 320 and transmission block 4 350 is the same as the width of the movable plate 200.

[0031] Specifically, as needed, standby transmission blocks of different widths can be sleeved on the connecting shaft 310. When the transmission block is needed, it only needs to be rotated around the connecting shaft 310 to the upper position of the fixed block 141, wherein the distance between the transmission block 1 320 and the transmission block 4 350 is the same as the width of the movable plate 200, so that the width of the movable plate 200 satisfies that the transmission blocks in different positions can be moved downward by the movable plate 200 after rotating to the upper part of the fixed block 141, and then the fixed block 141 is driven downward by the transmission block, and the bottom ends of the movable plate 200, the transmission block 1 320, the transmission block 2 330, the transmission block 340 and the transmission block 4 350 are all arranged to be arc-shaped surfaces, so that the bottom end of the movable plate 200 can push the transmission block smoothly.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0033] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
