Description

Technical Field

[0001] The utility model belongs to the field of molds for vulcanizers, and in particular relates to a multi-layer mold with a connection structure. Background Art

[0002] A vulcanizer is a type of molding machine, typically used for molding materials such as rubber and plastic. During the vulcanization process, the wound product is placed in the vulcanizer, where it is heated, pressurized, and inflated to create a tight fit between the product and the mold.

[0003] The existing vulcanizer mold structure is generally divided into three layers, namely the lower, middle and upper molds from bottom to top. The lower layer is used for heating or gas flow, the middle layer is generally used to support the product, and the upper layer is used to crimp the middle layer template. Although the traditional mold structure can perform basic vulcanization operations on the product, in actual use, we found that due to the influence of factors such as vulcanization molding heating and gas flow, this multi-layer mold is prone to deviation during use. Therefore, we have introduced a multi-layer mold with a connection structure to solve the above problem. Utility Model Content

[0004] In response to one or more of the above-mentioned defects or improvement needs of the prior art, the utility model provides a multi-layer mold with a connection structure, which enables the upper, middle and lower layer templates to remain stable after stacking by setting a connection limiting structure between the middle layer template and the lower layer template, and between the middle layer template and the upper layer template, while ensuring the sealing inside the cavity. Moreover, this structure can be adapted to different mold structures as an independent setting, and has good use value and application prospects.

[0005] To achieve the above-mentioned object, the present invention provides a multi-layer mold with a connection structure, which includes a lower template, a middle template, and an upper template arranged in sequence along the vertical direction; a vulcanization molding chamber for accommodating the product is formed between the middle template and the lower template;

[0009] A vertical displacement module is provided on the side of the movable plate away from the center of the lower template, and a connecting frame is provided at the telescopic end of the vertical displacement module. A second pressing plate is provided on the side of the connecting frame close to the upper template, which is used to press the top of the upper template after lateral movement.

[0010] As a further improvement of the present invention, the connection limiting structure also includes a movable rod, which is arranged on the side of the movable plate close to the center of the lower layer template. One end of the movable rod is connected to a push plate, and the other end of the push plate is provided with a sliding rod. The sliding rod slides horizontally through the middle layer template for plugging and fixing the middle layer template.

[0011] As a further improvement of the present invention, a limiting block is provided at one end of the sliding rod away from the push plate; corresponding to the limiting block, limiting grooves are provided on the lower template and the middle template, and the limiting block can move in the two limiting grooves driven by the sliding rod to achieve locking of the middle template and the lower template.

[0034] Preferably, if Figure 1 As shown in FIG, the middle template 200 in the multi-layer mold structure is embedded in the lower template 100, and the upper template 300 is placed on the middle template 200. A vent hole 101 is opened in the lower template 100, and a gas valve is provided corresponding to the vent hole 101 to control the inflow and outflow of gas. A hydraulic rod 500 is provided corresponding to the upper template 300 to drive the upper template 300 in vertical movement.

At this time, the operator can control the movement of the lateral displacement module 401 to press the first pressure plate 407 onto the middle template 200. Since the middle template 200 is integrally embedded in the lower template 100, the two can maintain stability after the first pressure plate 407 is pressed. The operator can then control the movement of the upper template 100 to press it onto the middle template 200, and at the same time control the second pressure plate 411 to perform a secondary limit on the upper template 300 to improve the stability of the overall structure.

[0036] More specifically, Figure 2 As shown in , the connection and limiting structure 400 in the preferred embodiment of the present invention further includes a movable rod 403, which is arranged on the side of the movable plate 402 near the center of the lower template 100.
