Description

Technical Field

[0001] This utility model relates to the field of bottle processing technology, and more specifically, to an auxiliary structure for protecting the movement of a preform mold slider. Background Technology

[0002] In the machining process of preform molds, the slider plate typically reciprocates along the base guide rail to open and close the mold. In existing technologies, the slider plate tends to shift downwards due to its own weight, leading to the following problems over long-term operation: the slider's downward movement causes uneven stress on the mold teeth, accelerating taper wear and affecting product molding accuracy; the contact surface between the guide rail and the slider plate is subjected to excessive pressure over a long period, easily leading to wear or deformation of the mating surfaces. Traditional solutions often rely on reinforcing materials or complex buffer structures, but these are costly and inconvenient to maintain. Utility Model Content

[0003] The present invention provides an auxiliary structure for protecting the sliding block of an injection mold. It has a simple structure, low cost, and can stably support the sliding block, thus solving the problem of sagging.

[0004] To alleviate the above problems, the technical solution adopted by this utility model is as follows: A protective auxiliary structure for the sliding block movement of an injection mold includes a base, a sliding block, and a copper pad. The base is provided with a guide rail, the sliding block is slidably assembled on the guide rail, and the sliding block is rigidly connected to the copper pad. The base has an installation groove, in which a limit block is fixedly installed. The lower surface of the copper pad contacts and is supported by the upper surface of the limit block.

[0005] Preferably, the limiting block is fixedly installed on the base by bolts.

[0006] Preferably, the limiting block has a convex-shaped structure, with its lower, larger portion engaging with the mounting groove and supporting the lower surface of the copper pad, while its upper, smaller portion is fitted with the notch.

[0007] Compared with the prior art, the beneficial effects of this utility model are: 1) The limiting block directly supports the copper pad, shares the weight of the slider plate, avoids displacement deviation caused by its own weight, and ensures stable accuracy of the tooth taper. 2) Reduce the vertical pressure of the slider plate on the working surface of the guide rail, reduce the wear rate of the sliding mating surface, and extend the service life of the guide rail and slider plate; 3) Reduce downtime for maintenance due to loss of precision or damage to components, and significantly extend the continuous production cycle of molds; 4) The limit block is fixed by the mounting slot, which eliminates the need for complex drive or adjustment mechanisms, resulting in low manufacturing costs and easy maintenance.

[0008] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0009] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0011] 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 some embodiments of this utility model, but not all embodiments.

[0012] Please refer to Figure 1 and Figure 2 This embodiment provides an auxiliary structure for protecting the sliding block of an injection mold, including a base 1, a sliding block 2, and a copper pad 4. The base 1 is provided with a guide rail, the sliding block 2 is slidably mounted on the guide rail, and the sliding block 2 is rigidly connected to the copper pad 4. The base 1 is provided with an installation groove 5, and a limit block 3 is installed in the installation groove 5. The limit block 3 is fixedly installed on the base 1 by bolts. The lower surface of the copper pad 4 contacts and is supported by the upper surface of the limit block 3.

[0013] This structure utilizes the contact support relationship between the copper pad 4 and the limiting block 3 to transfer part of the weight of the slider plate 2 to the limiting block 3, rather than having it entirely borne by the working surface of the guide rail.

[0014] In this embodiment, the limiting block 3 is Figure 3 The convex-shaped structure shown is as follows: Figure 1As shown, its lower, larger portion is engaged with the mounting groove 5 and supports the lower surface of the copper pad 4, while its upper, smaller portion is fitted with the notch 6 with a clearance fit. The engagement of the lower, larger portion with the mounting groove 5 achieves self-locking, while the clearance fit between the upper, smaller portion and the notch 6 provides a margin of movement.

[0015] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
