Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a new type of slider mechanical automatic gate cutting mechanism. Background Art

[0002] In injection molding production, the traditional method of cutting the gate is to add an ejector plate ejection mechanism to the slider. When the mold is opened, the gate is broken by the spring force.

[0003] During continuous production, the spring is prone to elastic fatigue, resulting in the state that the ejector pin does not return after ejection, causing mold clamping collision. Moreover, the mold size will be very large, which is not suitable for actual production. Obviously, in this case, the slider ejector plate spring return mechanism increases the risk of mold clamping collision in mechanized production and increases the risk cost of mold repair. However, this new type of slider mechanical automatic gate cutting mechanism realizes mechanized slider reset by flexibly using the combination of upward and reverse sliders, improves the quality of sustainable and safe products, and realizes the innovation of mold technology. Summary of the Utility Model

[0004] Purpose of the Utility Model: The purpose of the utility model is to solve the problems that during continuous production, the spring is prone to elastic fatigue, resulting in the state that the ejector pin does not return, causing mold clamping collision and being not suitable for actual safe production.

[0005] Technical Solution: A new type of slider mechanical automatic gate cutting mechanism includes a large slider seat. The upper surface of the large slider seat is provided with a plurality of small slider seats. Small inclined pins are arranged inside each of the plurality of small slider seats. Two large inclined pins are arranged on the upper surface inside the large slider seat. The bottom ends of the two inclined pins both extend below the large slider seat.

[0006] Furthermore, a plurality of products are arranged on the front surface of the large slider seat. A sleeve is arranged on the lower surface of the products. Small slider ejector pins are arranged on the front surface of each of the plurality of small slider seats. Gate bodies are arranged above each of the plurality of products.

[0007] Furthermore, guide plates are arranged on the left and right sides of each of the plurality of small slider seats. Fixed bolts are threadedly connected to the outer side walls of the plurality of guide plates and the inside of the large slider seat.

[0008] Furthermore, gate pins are arranged between every two adjacent products.

[0009] Beneficial Effects: The slider mechanical automatic gate cutting mechanism of the utility model solves the problem of safe production of the slider mechanical automatic gate cutting, also solves the problems of unstable return and spring failure of the traditional slider ejector plate spring due to elastic fatigue, and also avoids the problems of the state that the ejector pin does not return after ejection, causing mold clamping collision and the risk cost of mold repair.

[0013] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0014] Embodiment 1

[0015] As Figure 1 - Figure 2 shown, a new type of slide block mechanical automatic gate-cutting mechanism is provided, including a large slide block seat 1. A plurality of small slide block seats 2 are arranged on the upper surface of the large slide block seat 1. Small angled pins 3 are arranged inside each of the plurality of small slide block seats 2. Two large angled pins 4 are arranged on the inner upper surface of the large slide block seat 1. The bottom ends of the two angled pins extend below the large slide block seat 1. A plurality of products 5 are arranged on the front surface of the large slide block seat 1. An ejector sleeve 6 is arranged on the lower surface of the product 5. Small slide block ejector pins 7 are arranged on the front surface of each of the plurality of small slide block seats 2. Sprue bodies 8 are arranged above each of the plurality of products 5. Sprue pins 11 are arranged between two adjacent products 5;

[0016] During mold opening, the small angled pin 3 first drives the small slide block ejector pin 7 to cut off the sprue body 8, then the large angled pin 4 drives the large slide block seat 1 and the small slide block seat 2 to separate from the product 5, and finally the sprue pin 11 and the ejector sleeve 6 eject the sprue body 8 and the product 5 out of the mold. The large slide block seat 1 has a delayed clearance during mold opening. The plurality of small angled pins 3 pull the small slide block seat 2 to move in the reverse direction, so as to realize the small slide block ejector pin 7 cutting off the sprue body 8. During mold closing, the large slide block seat 1 closes first. After reaching a certain distance, the small angled pin 3 pulls the small slide block seat 2 to return, and the small slide block ejector pin 7 retracts into the small slide block seat 2, thus playing a role in preventing the small slide block ejector pin 7 from hitting the mold.

[0017] As Figure 1 shown, guide plates 9 are arranged on the left and right sides of each of the plurality of small slide block seats 2. Fixing bolts 10 are threadedly connected to the outer side walls of the plurality of guide plates 9 and the inside of the large slide block seat 1;

[0018] During the long-term operation process, the entire mechanism will be subjected to external forces such as vibrations and impacts to varying degrees. The guide plate 9 and the large slide block seat 1 are firmly connected by fixing bolts 10, forming a relatively rigid overall structure, which can effectively resist these external forces, maintain the stability of the mechanism operation, and at the same time, the accuracy of the sliding of the small slide block seat 2 can be ensured by the arranged guide plate 9.

[0019] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
