Description

Technical Field

[0001] This utility model relates to the field of mold spring block technology, specifically a front mold spring block assembly. Background Technology

[0002] In the production of injection molded products, if the molded part has shallow lateral undercuts on the inside or outside, a slanted ejector component is often required in the mold for smooth demolding. Slanted ejector components have a more significant advantage than side core pulls when handling injection molded parts with shallow lateral undercuts. They serve both molding and ejection functions and are a special type of component in the mold.

[0003] A front mold spring block mechanism for an intake manifold, disclosed in publication number CN105415602A, is used in conjunction with a rear mold for injection molding an intake manifold, forming an injection cavity between the front and rear molds. The spring block mechanism includes a spring block, a spring, a spring block limiting block I, and a spring block limiting block II. A forming insert is provided below the spring block mechanism. The spring block limiting block II is fixed to the front mold and has a protrusion II. A cavity is provided in the spring block limiting block I, and the spring is located within the cavity. A clearance travel groove is provided between the spring block limiting block I and the rear mold, located between protrusion I and protrusion II. The forming insert passes through the forming insert via a wedge and enters the groove I of the spring block limiting block I. When the injection molding machine opens the mold, the front mold insert can be demolded first under the action of the spring in the spring block mechanism.

[0004] While existing technologies have added springs to enable the front mold inserts to be ejected before injection molding, they cannot reasonably control the range of spring-off. Therefore, we propose a front mold spring block assembly. Utility Model Content

[0005] The purpose of this invention is to provide a front mold spring block assembly to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front mold spring block assembly, comprising two side plates, with spring blocks slidably mounted on the two side plate supports, a spring acting on the bottom of each spring block, a movable block disposed at the end of each spring block away from the spring, and second sliding grooves cooperating with the side plates disposed on both sides of the movable block; a second locking block is detachably mounted on one end of the spring block at the movable block, and a first locking block is disposed between the second locking block and the movable block.

[0007] Preferably, the side plate is provided with a guide protrusion on one side of the spring block, and the side of the spring block is provided with a first sliding groove that cooperates with the guide protrusion.

[0008] Preferably, one side of the guide protrusion is configured as a first inclined surface, the lower part of the other side of the guide protrusion is configured as a second inclined surface parallel to the first inclined surface, and the end of the guide protrusion located on the second inclined surface is configured as a vertical surface.

[0009] Preferably, the first slide is inclined, and the inclination angle of the first slide is the same as the inclination angle of the first inclined surface; the second slide is vertical, and the width of the second slide is greater than the width of the guide protrusion.

[0010] Preferably, both the first locking block and the second locking block have an L-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when the spring acts on the moving block, since the second slide groove of the moving block is vertically set and the width of the second slide groove is greater than the width of the guide protrusion, the range of spring opening will be limited, thereby ensuring the mold opening effect while controlling the stroke.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] Please see Figure 1-7 In this embodiment of the utility model, a front mold spring block assembly includes two side plates 1. Spring blocks 3 are slidably mounted on the two side plates 1. A spring 2 is installed at the bottom of the spring block 3 to act on the spring block 3. A movable block 4 is provided at the end of the spring block 3 away from the spring 2. Second sliding grooves 8 that cooperate with the side plates 1 are provided on both sides of the movable block 4. A second locking block 6 is detachably installed at one end of the spring block 3 located on the movable block 4. A first locking block 5 is provided between the second locking block 6 and the movable block 4. Both the first locking block 5 and the second locking block 6 are L-shaped structures. When the spring 2 acts on the movable block 4, since the second sliding groove 8 of the movable block 4 is vertically arranged and the width of the second sliding groove 8 is greater than the width of the guide protrusion 11, the range of spring opening is limited, thereby ensuring the mold opening effect while controlling the stroke.

[0023] The side plate 1 is provided with a guide protrusion 11 on one side of the spring block 3. The side of the spring block 3 is provided with a first sliding groove 7 that cooperates with the guide protrusion 11. The first sliding groove 7 and the side of the guide protrusion 11 fit together to ensure the stability of the stroke. One side of the guide protrusion 11 is provided with a first inclined surface 111. The lower part of the other side of the guide protrusion 11 is provided with a second inclined surface 112 that is parallel to the first inclined surface 111. One end of the guide protrusion 11 located on the second inclined surface 112 is provided with a vertical surface 113. The first sliding groove 7 is inclined, and the inclination angle of the first sliding groove 7 is the same as the inclination angle of the first inclined surface 111. The second sliding groove 8 is vertical, and the width of the second sliding groove 8 is greater than the width of the guide protrusion 11.

[0024] The working principle of this utility model is as follows: When the spring 2 acts on the moving block 4, since the second slide groove 8 of the moving block 4 is vertically set and the width of the second slide groove 8 is greater than the width of the guide protrusion 11, the range of the spring opening will be limited, thereby ensuring the mold opening effect while controlling the stroke.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
