Problems solved by technology

[0003] When the hard rubber product is placed in the overmolding mold for injection molding, the hard rubber product cannot be kept in the center of the mold (up, down, left, and right) under the impact of the injection pressure, resulting in uneven distribution of the soft rubber on the outside. The difference in wall thickness is too much, and even glue leakage occurs, which affects the appearance and use

Embodiment 1

[0019] See figure 1 and figure 2 , the present invention includes a fixed clamp block 1, a movable clamp block 2 and a drive rack 3; the fixed clamp block 1 and the drive rack 3 are fixedly arranged on the movable mold 4; the fixed mold 5 is provided with a drive tooth The notch 51 where the bar 3 is inserted is connected to the installation groove 52 for installing the movable clamp block 2, and the notch 51 communicates with the installation groove 52; the movable clamp block 2 is rotatably arranged in the installation groove 52; Part 21 and transmission tooth part 22.

[0020] One end of the clamping part 21 close to the notch 51 is connected side by side with the transmission tooth part 22 to form a whole, and the other end of the clamping part 21 and the fixed clamping block 1 form a positioning clamping part for positioning and clamping the workpiece.

[0021] Said transmission tooth portion 22 is fan-shaped; the arc edge of said transmission tooth portion 22 is provi...

Embodiment 2

[0025] See image 3 In the present invention, the clamping part 21 is rotatably arranged in the installation groove 52; one end of the clamping part 21 close to the notch 51 is provided with a transmission tooth part 22, and the other end of the clamping part 21 forms a positioning clamp with the fixed clamping block 1 tight part. Other technical features are the same as those in Embodiment 1.

Abstract

The invention relates to a locating device of a handle rubber coating mold. The locating device comprises a fixed clamping block, a movable clamping block and a driving rack. The fixed clamping block and the driving rack are both fixedly arranged on a moving mold. The moving mold is provided with a notch for allowing the driving rack to be inserted and a mounting groove for allowing the movable clamping block to be mounted, and the notch communicates with the mounting groove. The movable clamping block is rotationally arranged in the mounting groove. The movable clamping block comprises a clamping part and a transmission tooth part. The driving rack is matched with the transmission tooth part. The clamping part and the fixed clamping block are matched to form a locating and clamping part for locating and clamping a workpiece. According to the locating device, the workpiece in a rubber coating cavity can be effectively located, the problem that the workpiece deviates under the action of injection molding pressure is avoided, and therefore rubber coating quality is improved.

Description

technical field [0001] The invention relates to the field of rubber overmolding, in particular to a positioning device for a handle overmolding. Background technique [0002] Ordinary plastic products have a hard surface after cooling. In order to improve the hand feeling and prevent slipping, many functional plastic products on the market now wrap a layer of elastomer soft rubber on the outside of the hard rubber. The production process of this kind of soft rubber products needs to inject hard rubber products first, and then put the hard rubber products into the overmolding mold for injection molding, so as to form a layer of elastomer soft rubber on the hard rubber products. [0003] When the hard rubber product is placed in the overmolding mold for injection molding, the hard rubber product cannot be kept in the center of the mold (up, down, left, and right) under the impact of the injection pressure, resulting in uneven distribution of the soft rubber on the outside. Th...
