Description

Technical Field

[0001] This utility model relates to the field of injection molding tooling technology, specifically a tooling for slide injection molding. Background Technology

[0002] The slide of a CNC hub lathe moves along the Z-axis on the bed. To accommodate heavy-load, high-power cutting, improve rigidity and wear resistance, and reduce noise and vibration during operation, its sliding surface is injection molded. This results in a low coefficient of friction and a long service life. Previously, without tooling, injection molding of the slide required placing it on a pre-machined bed and using the bed guideways as a reference. This could only be done after the bed was completed, impacting machining schedules and production coordination. Utility Model Content

[0003] The purpose of this invention is to provide a tooling for slide injection molding. This tooling has a simple and reasonable structure, and can perform guide rail injection molding on the slide at any time according to the production schedule. It is highly adaptable, can meet the injection molding requirements of the slide, and improves production efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a tooling for slide injection molding, the structure of which includes a base, a first guide rail, a second guide rail, a pressure plate and a baffle. The first guide rail and the second guide rail are respectively provided on the top wall of the base. The first guide rail and the second guide rail are respectively provided with positioning bosses that are connected to the slide. The corresponding sides of the first guide rail and the second guide rail are respectively provided with baffles. The baffles are movably connected to the side walls of the slide. The pressure plate is provided in the upper part between the first guide rail and the second guide rail. The two ends of the pressure plate are respectively connected to the base by screws.

[0005] Furthermore, the side wall of the second guide rail is provided with a wedge, the straight surface of which is in contact with the side of the second guide rail, and the inclined surface is in contact with the slide plate, and the length is consistent with the length of the two guide rails.

[0006] Furthermore, the top of the first guide rail, the top of the second guide rail, and the side of the guide rail are respectively provided with positioning bosses that are engaged with the injection molding reference surface of the slide guide rail.

[0007] Furthermore, the first guide rail and the second guide rail are respectively fixed to the base by internal threaded tapered pins and internal hexagonal cylindrical head threads.

[0008] Furthermore, the top wall of the slide plate is provided with two injection holes, through which injection molding material is injected by an injection molding machine.

[0009] Furthermore, the top wall of the slide plate is provided with four threaded holes at both ends of guide rail one and guide rail two, and the threaded holes are fitted with nuts.

[0010] The beneficial effects of this utility model are:

[0011] The injection molding fixture of this utility model uses two guide rails with corresponding cross-sectional dimensions fixed on the base according to the position of the bed guide rail as the reference surface for injection molding. It does not require waiting for the bed to be completed before injection molding can be carried out. Injection molding can be carried out at any time according to the production schedule and arrangement, which is highly adaptable. By inserting a wedge on one side of the guide rail, and the slope of the wedge is consistent with the slope of the slide, the sealing of the injection molding is improved.

[0012] Four threaded holes are provided on the top wall of the slide plate and at both ends of the two guide rails. The threaded holes are connected to the injection area. When the injection material emerges from the threaded holes, it means that the material has fully covered the part to be injected, and the injection can be stopped. The nut can be tightened here to prevent over-injection and waste of injection material. Attached Figure Description

[0019] The following is a detailed description of a tooling for slide injection molding according to the present invention, with reference to the accompanying drawings.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a tooling for slide injection molding, including a slide 10 for injection molding, a base 1, a first guide rail 2, a second guide rail 3, a pressure plate 5, and a baffle 6. The first guide rail 2 and the second guide rail 3 are respectively located on the top wall of the base 1. Baffles 6 are respectively provided on opposite sides of the first guide rail 2 and the second guide rail 3. The baffles 6 are movably connected to the side walls of the slide 10. The two baffles 6 are fixed to both ends of the slide by hexagonal head screws, thus sealing the injection space. The pressure plate 5 is located on the upper part of the slide between the first guide rail 2 and the second guide rail 3. Both ends of the pressure plate 5 are connected to the base 1 by screws 29. By setting the pressure plate 5, a certain pressure is applied to the slide after injection molding, ensuring a tight and firm injection layer. A wedge 4 is provided on the side wall of the second guide rail 3. The wedge 4 is inserted from the large end of the baffle 6, and the wedge is squeezed between the inclined surface of the slide and the guide rail surface, thus providing a sealing effect.

[0021] The guide rail 12 and guide rail 23 are respectively fixed to the base 1 by screw 18 and internal threaded conical pin. The top and side of the guide rail 12 and guide rail 23 are respectively provided with positioning bosses that engage with the injection reference surface of the slide 10 guide rail. During injection molding, the injection reference surface of the slide is in close contact with the positioning bosses of the two guide rails. The roughness and flatness of the positioning bosses are required to ensure the accuracy of injection molding.

[0022] The top wall of the slide plate 10 is provided with injection holes 11. There can be one or more injection holes 11, and the number of holes can vary depending on the injection requirements. This fixture is provided with one hole at the corresponding position in the middle of the two guide rails.

[0023] The top wall of the slide plate 10 is provided with threaded holes 12 at both ends corresponding to the guide rail 2 and the guide rail 3, and the threaded holes 12 are fitted with nuts. When the injection material emerges from the threaded holes, it means that the material has completely covered the part to be injected, and the injection can be stopped. At this point, the nuts can be tightened to prevent over-injection and waste of injection material.

[0024] The slide plate 10 is fixedly installed on the tooling via two guide rails on the base 1. Then, baffles 6 are installed at both ends of the slide plate. The wedge 4 is inserted through the large opening between the baffle 6 and the guide rail. At this time, the injection space is sealed by the baffles and the wedge. Then, the material is injected through the injection hole 11 at the top of the slide plate 10. When the injection material emerges from the threaded hole 12 at the top of the slide plate, it means that the material has completely covered the part to be injected. Stop the injection and tighten the nut. After the injection is completed, the pressure plate 5 is fixed to the base 1 with hexagon socket head cap screws and pressed tightly against the top of the slide plate.

[0025] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.

[0026] Apart from the technical features described in the specification, all other technical features are known to those skilled in the art.
