Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to an anti-retraction mold structure of a slide block driven by an oil cylinder. Background Art

[0002] The mold is a tool used to make molded products. Different shapes of molds are used to make products of different shapes, such as Figure 1 The steam engine casing shown in the figure has a large overall size. A V-shaped channel is opened on the side of the steam engine casing. In order to form the V-shaped channel, a slider needs to be installed slidably on the side during mold closing and injection molding. The movement of the slider is traditionally controlled by a hydraulic cylinder arranged on the side. Due to the large overall size of the steam engine casing, multiple hot injection nozzles are used to inject glue in order to improve the molding efficiency. When the injection pressure is too high, the oil cylinder cannot supply oil at the same time and loses pressure, causing the slider to retreat, thereby affecting the product quality, generating burrs around the circle, and increasing the cost of manual rework.

[0032] Example

[0033] like Figure 1 The steam engine housing 70 shown has a large overall size, and a V-shaped channel 701 is opened on the side of the steam engine housing 70.

[0034] Reference Figure 2-6 As shown, the utility model discloses a slide block anti-retraction mold structure driven by an oil cylinder 311, comprising a panel 10, a nozzle plate 20, an upper movable mold 30, a lower fixed mold 40, an ejector plate 50 and a bottom plate 60 from top to bottom, the upper movable mold 30 is provided with a molding groove, a molding block 301 is embedded in the molding groove, and an annular protrusion 401 is embedded on the lower fixed mold 40. Specifically, when the mold is closed, the upper movable mold 30 and the lower fixed mold 40 are closed, and the protrusion 401 is placed between the inner side wall of the molding groove and the molding block 301, which is used to form the main body of the steam engine housing 70. When the mold is opened, the upper movable mold 30 drives the molding block 301 to leave the annular protrusion 401, and the product falls on the protrusion 401. Furthermore, the lower fixed mold 40 is provided with a push block 402 around the protruding portion 401, and a push rod is installed on the ejector plate 50, the push rod is upwardly connected to the push block 402, and the ejector plate 50 pushes the product upward from the protruding portion 401 through the push block 402 to realize product demoulding.

[0035] Reference Figure 3-8As shown, a side forming mechanism 31 is arranged on the side of the upper movable mold 30, and the side forming mechanism 31 includes a side slider 313 and a cylinder 311. A V-shaped through hole 302 connected to the forming groove is opened on the side of the upper movable mold 30, and the side slider 313 can be slidably placed in the V-shaped through hole 302. The side slider 313 is opened with an inclined T-shaped groove, and the cylinder 311 is vertically embedded in the side of the panel 10 and the hot nozzle plate 20. The piston rod of the cylinder 311 faces downward and is provided with an inclined guide block, and the inclined guide block 312 is placed in the T-shaped groove. A positioning groove 314 is opened below the T-shaped groove of the upper movable mold 30, and the up and down movement of the inclined guide block 312 drives the side slider 313 to move along the V-shaped through hole 302. Specifically, during mold closing and injection molding, the upper movable mold 30 and the lower fixed mold 40 are closed, and the control cylinder 311 is extended downward to push the oblique guide block 312 to move downward. The oblique guide block 312 is placed in the inclined T-slot. When the oblique guide block 312 moves downward along the inclined T-slot, it pushes the side slide block 313 toward the molding block 301. When the side slide block 313 is close to the side of the molding block 301, the lower end of the oblique guide block 312 is placed in the positioning groove 314. In this way, when multiple hot nozzles are injected at the same time, the pressure in the cavity cannot push the side slide block 313 to retreat. Compared with the traditional method of directly supporting the side slide block 313 with the cylinder 311 perpendicular to the end face, the utility model can prevent the side slide block 313 from retreating after the cylinder 311 cannot supply oil and loses pressure, which can avoid burrs around the product and reduce the cost of manual rework.

[0036] Reference Figure 3-8 As shown, a baffle is installed on the side of the upper movable mold 30, and a vertical strip hole is opened on the baffle. Limit sensors 315 are installed at the upper and lower ends of the strip hole of the baffle. The inclined guide block 312 is provided with a limit rod 3121, and the limit rod 3121 extends out of the strip hole. The upper limit sensor 315 is used to limit the upper limit position of the inclined guide block 312 moving upward, and the lower limit sensor 315 is used to limit the lower limit position of the inclined guide block 312, and the corresponding side slider 313 leaves or is close to the molding block 301.

[0037] Reference Figure 3-8 As shown, a cushion block 3141 is arranged in the positioning groove 314. The cushion block 3141 is installed in the positioning groove 314, and the thickness of the cushion block 3141 can be processed separately to adjust the matching with the oblique guide block 312 so that there is no gap between the oblique guide block 312 and the cushion block 3141. The cushion block 3141 pushes the oblique guide block 312 to limit the retreat of the side slide block 313. Furthermore, an inverted T-shaped guide groove is opened on the oblique guide block 312, and the piston rod of the oil cylinder 311 is installed on the round table, and the round table moves along the guide groove. Through the cooperation of the round table and the guide groove, it is convenient to install and remove the piston rod of the oil cylinder 311 on the oblique guide block 312, thereby improving production efficiency.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
